[LED Technology Broadcasting] Five Technology Highlights of LED Display Screen

Technology 1: how to automatically switch on and off the LED display screen at fixed time

1 BIOS setting fixed-point automatic power on every day

Step 1: start the LED display server computer, press del, enter BIOS, and then select "power management features"

, enter. Find the item "restore on AC / power loss" in the power window, press enter, and then set its value to "power on" through the direction key;

Step 2: select "resume onrtc alarm" and press enter, and then set its value to "enable" through the direction key; Step 3: select RTC

"Alarmdate" press enter, and then set its value to "every day", indicating that the same operation is performed every day. According to the same method, respectively "RTC alarm"

"Second" is set to "07", "55" and "00", which means that the startup time is "7:55:00" in the morning. After all settings are set, press F10 to save and restart.

Because the BIOS of different motherboards is different, the settings of some motherboards may be a little different from those above, but just remember to find "wake up" or "resume by" in power management

The word "alarm" is OK, because this is the option to set the timed startup.

2 With the help of shortcuts, the display information file is automatically run after startup

Step 1: associate the display file with the display program. For example, the display file is "common. Led", and the program to open it is "led. Exe". Just click "common. L e" with the right mouse button

D "icon, click" attribute ", click" change "button in the" general "option, find the program" led.exe ", and click" OK ";

Step 2: generate a shortcut to the display file. Right click the "common. Led" icon and click "create shortcut" to display a "shortcut to"

Click "common. Led" icon, then click "start", "run" and "Browse" in the lower left corner of the computer display screen, find the "shortcut to common. Led" file and confirm it, and copy the ""... Shortcut in the "open" column

To the common. Led. LNK ''. Note: if you click "OK", you can directly open the display file "common. Led";

Step 3: set the startup item in the super rabbit. Download the super rabbit software on the Internet and install it into the LED display server computer. Open the "magic settings - create your own system" in the "rabbit tool", right-click in the "startup program", select "new project", and paste it in the "command line"

D: Led shortcut to "common. Led. LNK", the title is set by yourself.

After this setting, the startup will automatically run the display file "common. Led", which has the same effect as manually opening "common. Led".

Technology 2: how to detect the quality of LED display pixels from the unit board

"Pixel" is a unit used to calculate digital images. Like photographic photos, digital images also have continuous shades. If we enlarge the image several times, we will find that these continuous tones are actually composed of many small square points with similar colors. These small square points are the smallest unit "pixel" of the image. This smallest graphic unit can be displayed on the screen, usually a single dye point.

According to the color principle, we know that red (R), green (g) and blue (b) are called three primary colors. These three colors can be combined to obtain any color from black to white. In the classification of LED display screen, there are monochrome display screen, two-color display screen and full-color display screen. Monochrome is relatively simple. You only need to select any one of the three primary colors to realize monochrome display. In practical application, there are many red LED lamps. In this way, a red LED is a pixel.

The two-color display screen is similar to the monochrome display screen. As long as any two of the three primary colors are selected, the two-color display can be realized. In practical application, red and green are often selected. When red and green are on at the same time, yellow can be realized. Therefore, the two-color display can realize three colors: red, green and yellow.

How to Quickly Solve the Heat Dissipation Problem of LED Display Screen
How to Quickly Solve the Heat Dissipation Problem of LED Display Screen
?1. The fatal bane of electronic products is that the temperature is too high, because high temperature will lead to a series of problems such as reduced reliability, unstable performance and shortened service life of electronic products. The display screen is also afraid of high temperature, so engineers have taken various methods to solve the heat dissipation problem in order to control the temperature of electronic parts inside the display screen and make it not exceed the specified higher allowable temperature under the working environment conditions of the display screen.2. In fact, when selecting the heat dissipation mode, we should consider the following issues: heat flux density, volume power density, total power consumption, surface area, volume, working environment conditions (temperature, humidity, air pressure, dust, etc.) of the display screen.3. According to the principle of heat conduction, there are natural cooling, forced air cooling and direct liquid cooling; Evaporation cooling; Thermoelectric cooling; Heat pipe heat transfer and other heat dissipation methods.Common heat dissipation methods of display1. It is a common method to use a long-life and high-energy fan to strengthen heat dissipation inside the lamp shell. This method has low cost and good effect.2. Aluminum cooling fins are used, which is a common heat dissipation method. Aluminum cooling fins are used as part of the shell to increase the heat dissipation area.3. Aerodynamics, using the shell shape to produce convective air, which is a low-cost method to strengthen heat dissipation.4. Surface radiation heat dissipation treatment: the surface of the lamp shell is treated with radiation heat dissipation. The simpler thing is to apply radiation heat dissipation paint, which can bring the heat away from the surface of the lamp shell by radiation.5. The purpose of heat conduction and heat dissipation is to reduce the working temperature of the high-definition display chip. Due to the large difference between the expansion coefficient of the chip and the expansion coefficient of our common metal heat conduction and heat dissipation materials, the chip cannot be directly welded to avoid the high and low temperature thermal stress damaging the display chip.6. The heat conduction tube is used for heat dissipation, and the heat is guided from the display chip to the shell heat dissipation fin by using the heat conduction tube technology.7. The heat conducting plastic shell is made of heat conducting plastic material during injection molding of the plastic shell, so as to increase the heat conduction and heat dissipation capacity of the plastic shell.Advantages and applications of digital displayDigital display is a display that receives and processes digital signals.

How to Choose a Led Display Screen for Your Premies to Attract Customer
How to Choose a Led Display Screen for Your Premies to Attract Customer
Before we dive into this topic today, let me tell you the professional definition from wikipedia.orgA LED display is a flat panel display that uses an array of light-emitting diodes as pixels for a video display. Their brightness allows them to be used outdoors where they are visible in the sun for store signs and billboards. In recent years, they have also become commonly used in destination signs on public transport vehicles, as well as variable-message signs on highways. LED displays are capable of providing general illumination in addition to visual display, as when used for stage lighting or other decorative (as opposed to informational) purposes. LED displays can offer higher contrast ratios than a projector and are thus an alternative to traditional projection screens, and they can be used for large, uninterrupted (without a visible grid arising from the bezels of individual displays) video walls. microLED displays are LED displays with smaller LEDs, which poses significant development challenges.Due to the growing demand of modern digital display, Led display screen (also called Led video wall) is widely used on various places, How to choose a suitable led display screen is always a headache for our clients, because there are a large number of type in the market. hence we conclude few way to help our clients to find the suitable screen according to their requirement based on the feature of each type of led display screens. These features that decide which screen to use including the following: installation place, Ambient brightness, content to display, capacity of content, Viewing distance, Display proportion, below we will have a discussion for some of the point,Led displays mainly used for advertising, broadcasting, we need to consider the place to install the led screen, based on the place, we can divide the screen to indoor, outdoor, semi-outdoor. Indoor display screen screens likewise offer smooth screens that are optimal for ambient illumination as well as shorter watching distances. LED video wall surfaces make the interior setting extra interesting by supplying an incredible viewing experience- in retail stores, corporate entrance halls, and so on . Besides normal indoor as well as exterior display screen screens, there are also semi-outdoor screens. These are seen in open halls, under eaves, sometimes below sun roofings and even under an outdoor canopy.However, despite providing the very same ultra-high brightness as outside LED screens, these semi-outdoor screens are not immune to negative weather. Distinctions in between indoor as well as exterior LEDsOutdoor LED displays are mainly utilized at places where a mega program gets on- for brand name ads, as an example, as they can provide full colour as well as really high brightness. Interior LED displays, on the other hand, can not attend to the requirements of mega exterior screen jobs but are excellent for interior applications. They supply far better spectrophotometric colour. Besides this, they also offer high colour saturation.The elements that separate outside as well as indoor LED display screens are checked out in this write-up. Brightness This is certainly one of the striking distinctions between indoor as well as outdoor LED display screen screens. Bright sunshine can make it illegible boring or less brilliant LED indications. Thus, to provide ultra-high illumination, outside LED display screen screens are power-packed with numerous bright LEDs in one pixel. Since interior signs are not seen under the severe glare of the sunlight, they require to be much less intense, by default.Outside display screens use several times more brightness than indoor LED displays. Brightness is measured by systems called nits or candelas per square metre. The greater the luminance level, the higher the degree of illumination. Durability to exterior weather Exterior LED screen screens must be very leak-proof, water resistant, dust-proof, legible in sunshine, anti-lightning and resistant to high temperatures. Indoor LED screen screens do not require to supply the exact same resistance to the outdoors environment as well as thus do not included such features.The outdoor LED displays normally have IP65 water-proof levels while interior displays have IP20 waterproof degrees. Display resolution Outdoor LED screen display screens will certainly be generally viewed from more distances as contrasted to their interior equivalents, thus they have a lower resolution. Given that the range between the audience and an indoor LED screen is much shorter, usually, the resolution for interior LED display screens requires to be high. The greater the resolution the better the picture quality. The pixel pitch, which defines the density of the pixels on an LED display screen, is an additional differentiating variable between indoor and also exterior screen screens.Outdoor display screens have a bigger pixel pitch and a reduced resolution, whereas indoor display screens that need a high resolution for close watching have a smaller sized pixel pitch. Points to keep in mind while selecting LED moving display screens Interior LED screen displays can be created in a number of ways, depending upon the arrangement as well as building demands. This is because they do not call for a cupboard for setup. On the other hand, outside LED indications can not be put together panel by panel on the website. The entire installation is based upon the style (as a sign or billboard), or is put on a structure.The sort of LED screen picked should depend on whether it will certainly be positioned indoors or outdoors. After that consider the dimension of the positioning location or installment site, check if there is a remote demand by means of a PC, and also find out the minimum or least viewing distance. The default design of interior LED display screens is for very easy and also quick combination with several input sources as well as third-party gamers. Nevertheless, exterior LED screen displays need a sturdy regulator or controller for playback functions. They are typically managed through a copyrighted software suite, which additionally provides remote access in addition to indicator diagnostics.Screens with higher illumination are costly and also eat more electrical power. Therefore, it is very important to pick a screen with the right illumination for your needs, to ensure that you do not pay even more for something that is not essential. Non-weatherproof interior LED screens utilize LEDs with reduced light outcome, yet water-resistant outside LED screens need to make use of brighter LEDs.what products we are providing in this category1), Indoor single and dual display board, these kind of screen installed at indoor places, such as service counter at banks, postal offices,and government offices ,we can use products like model F3.75 and F5.0 indoor single and dual color screens.2), Indoor full color led displays, these kind of screen also installed at indoor places, such as shopping center, cinema, showroom, in order to play all kind of advertising video and photos, we can use indoor Q2.5IS, Q3IS , Q4IS etc3),outdoor led display screen, these kind of screen used at outdoor places, it consist of high brightness, high IP(ingress protection) grade, high display performance, which makes it the prior choice for outdoor display, mainly used at outside of shopping center, stadiums, commercial buildings, such as our outdoor Q5OS, Q6OS, Q8OS4), As the technology growing up, new type and design of led display screen are invented to the market, such as indoor and outdoor led video floor, indoor and outdoor transparent screen, flexible led screen, etcs,Based on the places of usage, different brightness should be chooses. CD is a numeric unit to metricThe purpose of installing the video wall will decide to choice the resolution.1), subtitles, depends on the size of text to decide the resolution. What content to play should be consider before select the led video wall, the single slide content is limit even though the total content can be expanded. Viewing distance also should be considered, if the audience are looking at a close distance, we should choose a small pitch screen, if the audience look at a far distance, we can choose a bigger size, but bigger pitch video wall.For example , a customer bought a Q10 screen: width is 9.6m, height is 5.76m, please tell the minimum viewing distance, best viewing distance, and farest viewing distance. Since we know the pixel pitch is 10mm, so,The best viewing distance is : 10*3=30mIn order to reach the best display performance, normally we use width:height proportion of 4:3, or 16:9, or nearest proportion. For example a customer has a 70sqm screen, and he want to install it according to 16:9 proportion , there is a formula to calculate:The above content is our many years experience in led screen field , today, I am sharing with you, so that you can help your customer to select the best led screen for customer,.Given current technology, could TV display screens double as video camera sensors?NoScreens these days are sheets of LED lights so that might work as a solar panel but not as a camera. At best you might measure ambient light levels perhaps but no camera. That said TV these days are coming out with built in cameras and microphones and will get worse as time goes by. Things like Google Assistant and Alexa will come built into a lot of household devices
How to Realize the Intelligent Configuration Design of LED Display Screen in Installation and Debugg
How to Realize the Intelligent Configuration Design of LED Display Screen in Installation and Debugg
introductionIn recent years, with the rapid development of LED industry, there are many display models and specifications, and a hundred flowers bloom, which not only gives users more choices, but also makes the display effect of LED display more colorful. However, too many models and specifications bring some problems in engineering application. Due to many manufacturers and no unified standards, the installation and commissioning of LED display screen has become a very heavy work. In addition, the installation and commissioning involves more than 20 parameters, and the requirements are very high. Generally, only professional technicians can complete it. In fact, most of the installation and commissioning are repetitive work, which makes many professional and technical personnel fall into the on-site commissioning of various projects, resulting in a great waste of manpower. Therefore, some people put forward that it is possible to debug and form data files ahead of time, professional technicians do not need to go to the scene, and the general engineers can finish debugging at the scene downloading, so LED intelligent configuration technology arises at the historic moment. After market research, some LED control software has also realized the function of intelligent configuration, but the effect is not ideal, such as too many steps, non intuitive, complex and so on. Based on this, after research, this paper proposes an intelligent configuration method, which allows users to make choices only through the "next step", automatically complete the intelligent configuration in at least seven steps, debug successfully, and generate data files for storage and download.1. Main functional requirements analysis and model constructionDue to different manufacturers, the number of parameter items of their display screen is also different, but basically each display screen has more than 20 items. After analysis and classification, it can be divided into core parameters, basic parameters and auxiliary parameters.(1) Core parametersThe core parameters are necessary for the display screen. If the setting is incorrect, it will not be displayed if it is light, and it will burn the screen if it is heavy. The core parameters include 8 items: cascade direction, OE polarity, data polarity, display type, color, scanning mode, point sequence and line sequence.(2) Basic parametersBasic parameters are the basic parameters of the display screen. If they are not set correctly, they cannot communicate, do not display or display abnormally. The basic parameters include 12 items: display width, display height, control card address, baud rate, IP address, port number, MAC address, subnet mask, gateway, display refresh frequency, shift clock frequency and line blanking time.(3) Auxiliary parametersAuxiliary parameters are parameters set for better display and control, including control card name, communication display mark, brightness and on-off screen time.To sum up, a display screen needs to be correctly configured with more than 20 parameters to light up, which is cumbersome and complex. If the setting is incorrect, it will not be displayed at first, or it will burn down the display screen, resulting in significant economic losses and construction delay. This is because the price of general display screen is more than 1000 yuan, some even more than one million yuan. Therefore, for the sake of prudence and prudence, it is understandable that some LED control software has complex design and inconvenient use. In order to overcome the shortcomings of the existing software, reduce the use threshold and complete the hardware debugging of the display screen in a relaxed and natural process, after research, this paper constructs a complete display screen parameter configuration model and intelligent configuration model, as shown in Figure 1 and Figure 2.In Figure 1, for the configuration of basic parameters and auxiliary parameters, input boxes and selection boxes are provided. After user input and selection, it can be set directly by connecting the display screen. For the core parameters, three methods can be used: professional quick query, intelligent configuration and external file configuration.(1) Professional quick checkThe parameters of common and commonly used display screens are generally fixed. At this time, they can be sorted into files or tables in advance, and the configuration can be loaded during debugging.(2) Intelligent configurationFor the uncommon or uncertain display screen, its parameters are unknown. At this time, intelligent configuration can be adopted to determine its configuration parameters, and then save them for future use.(3) External file configurationImport an external file built by intelligent configuration or other methods into the configuration.Among the three configuration methods of core parameters, intelligent configuration is the focus of this paper. Its main processes and functions are as follows:(1) Start intelligent configuration;(2) Through the wizard, let the user and the display screen make human-computer interaction selection, start the intelligent configuration operation, and complete the determination of core parameters by filling in initial parameters, determining OE polarity / data polarity, determining color, determining scanning mode, determining point sequence, determining line sequence, generating configuration parameters, etc;(3) Return intelligent configuration parameters;(4) Connect the display screen and set parameters;(5) If it is correct, perform the output parameter operation;(6) Select an external file and save it for later download. At this point, the intelligent configuration of the display screen is completed.2 design and implementation of key functions2.1 fill in initial parametersThe whole intelligent setting process is operated for the display module. For the display screen, it is exactly to observe the first display module entering from the signal cascade direction. That is, if the signal cascade direction is from left to right, the first display module refers to the display module in the upper left corner of the display screen. If the signal cascade direction is from right to left, the first display module refers to the display module in the upper right corner of the display screen. In order to facilitate observation, only one display module is used for general intelligent setting, and confirm that the display module is good and fault-free (including lines or points without abnormal display).After selecting the display module, fill in the parameters such as signal cascade direction, number of module width points, number of module height points and display type, and then click next to start intelligent configuration.2.2 determining OE polarity and data polarityOE polarity and data polarity are extremely important parameters of the display screen, in which OE polarity determines whether the display screen is on, and data polarity determines whether the display is correct. If the OE polarity is incorrect, the display will not be lit, no matter what the data polarity is; If the data polarity is incorrect, the display is abnormal and is all on. Therefore, the primary task of intelligent configuration is to judge OE polarity and data polarity. The display module displays three options: "full bright", "full black / dark bright" and "other displays or irregular changes". If "other displays or irregular changes" is selected, it indicates that there is a problem with the hardware configuration. The intelligent configuration needs to be carried out after the hardware configuration is corrected. In the specific design, 0 represents the high level and 1 represents the low level. The values of OE polarity and data polarity are determined by sending the high and low levels in turn and the user selects on or off. In this way, there are four combinations of OE polarity and data polarity. Therefore, it takes only four steps to correctly judge the OE polarity and data polarity. As long as the corresponding values of OE polarity and data polarity are sent in turn, and then the user's selection at each step is recorded, the values of OE polarity and data polarity can be judged.2.3 color determinationGray free display screen is divided into monochrome, two-color and full-color, of which monochrome generally corresponds to red; Two colors are generally red and green; Full color is generally red, green and blue. For monochrome screen, this step can be omitted; For the two-color screen, send the red command. According to the displayed color, you can judge whether it is normal display or red and green reverse color; For the full-color screen, send red and green colors respectively. According to the displayed color, you can judge whether it is normal display or red green reverse color, red blue reverse color or green blue reverse color.2.4 determine scanning modeFor the scanning mode, the judgment formula is: module height / number of lit lines = scanning mode. In design, send the command to judge the scanning mode. According to the number of lines selected by the user, the scanning mode can be calculated by formula. Since the scanning mode is uncertain, the data output shall be carried out according to the high denominator scanning mode determined in the early stage, and the number of bright lines is capped as the module height parameter.2.5 determining the order of pointsIn fact, the LED display screen is displayed in the order of one point by one point, but it uses the delay characteristics of human vision to realize the effect of full screen image display update by quickly sending the images of all points on the full screen at one time. Therefore, the order of points must be determined before sending.In order to obtain the point sequence, you can send a point at an interval of one second, and then record its position. The specific implementation method is as follows:(1) Send dot command; (2) One LED pixel on the display module will be lit every second. Carefully observe the lighting sequence of these pixel points. After confirming the lighting sequence, you can click the grid on the corresponding position of the simulation display module diagram (each grid of the simulation diagram corresponds to a pixel of the display module) according to the lighting sequence; (3) Click "next" after dotting, and the system will automatically record the dotting sequence.In order to better help users determine the order of points, the system also provides functions such as re management, fallback, reset and deduction.2.6 determining line orderIn addition to the order of highlights, determine the line order of highlights. In order to obtain the row order, you can send a row every second, send a point for each row, and then record its position. The specific implementation method is as follows: after sending the line display command, observe the lighting sequence of the LED lights on the display driving board, and trace the corresponding sequence points at the relative position of the line sequence. When finished, click next to record the line sequence automatically.For the display screen with common specifications, the line sequence can be determined through the section "2.5 determining the point sequence". This step can be omitted. At the same time, in order to better help the user determine the line sequence, the system also provides the functions of re entering the line sequence, fallback, reset and so on.2.7 download parameters and complete intelligent configurationAfter the above parameters are determined, reorganize the sequence and format according to the display data configuration format, and then download to the display configuration, and then observe whether it is correct. If it is correct, the intelligent configuration is completed. In addition, if necessary, it can be saved to a file for later use; If it is not correct, analyze the reason, and then conduct intelligent configuration again.3 conclusionIn this paper, a method of intelligent configuration of LED display screen is realized by means of wizard, user selection state and automatic judgment. It is applied in LED navigator software and has been highly praised by users. Practice has proved that this method can help users quickly configure and light up the display screen, reduce the threshold of display screen installation and commissioning, and liberate professional technicians from engineering installation. In the future, technicians do not need to go to the site, and ordinary engineers can complete the corresponding work. They only need to download the corresponding data files without repeated debugging.
With the Rapid Development of LED, the Supporting Equipment of LED Display Screen Needs to Be Upgrad
With the Rapid Development of LED, the Supporting Equipment of LED Display Screen Needs to Be Upgrad
Manufacturing industry has always been known as the "mother of industry". Looking at the development of the global LED display industry, China is also a well deserved LED display manufacturing country. Even in these years of development, China's LED display screen is rewriting the world led display screen industry pattern. In this process, not only the application end products bear the brunt, but also the supporting products of the display screen play a very important role. As we all know, China's LED display industry started relatively late, and has made remarkable achievements in catching up in recent years. Moreover, with the gradual release of national favorable policies and market potential, led supporting equipment has also accelerated the upgrading and optimization of the industry.At present, the supply chain of supporting products of LED display screen in China is very extensive and complete. There is a systematic industrial chain from box to screw. And there are some enterprises with innovative consciousness and strong application R & D ability. However, generally speaking, the total number of LED supporting enterprises in China is not large. The development and broad market of LED display screen in recent years are gradually attracting more supporting manufacturers to join the industrial chain of LED display screen. The competition in the market is gradually increasing. At the same time, it also enhances the competitive awareness of enterprises, strengthens the close cooperation with LED display manufacturers in product R & D, and provides LED display manufacturers with more technical content and more competitive products. It promotes the development of the whole LED display screen in technology and product innovation. With the development of supporting enterprise technology and the improvement of quality, it also provides a strong backing for LED display screen and jointly promotes the progress of the industry.With the gradual expansion of the application scenario of LED display screen, the product demand of customers has also changed. When choosing products, they tend to meet their diversified and personalized needs. Among them, LED display box occupies an important position in the whole supporting equipment. LED display box materials are widely used, generally iron box, high-end can use die-casting aluminum, stainless steel, carbon fiber, magnesium alloy and nano polymer materials. The box plays an important role in the application of the whole display terminal. Protect the electronic components inside from the interference of the external environment, and have a good protective effect on the protection of components. At the same time, because it works in a high temperature environment, good box material selection can reduce the impact of service temperature on components in the process. Since the display screen is composed of multiple boxes spliced, the selection of box material will also affect the flatness of LED display screen, so the role of box in the display screen is also obvious.In recent years, with the development of display technology, the requirements of LED display manufacturers for box are also gradually improved. LED display supporting manufacturers have also launched carbon fiber LED display box, magnesium alloy LED display box, nano polymer LED display box, etc. through their own technical R & D and innovation. From the original iron box, to the die-casting aluminum box and the current carbon fiber box, the innovation and progress of LED display screen are inseparable from the efforts of manufacturers as supporting products.In the whole production cost of LED display screen, the cost of frame is about 3% 5%. Although the proportion is not high, it largely determines the appearance and grade of LED display screen. Therefore, as a manufacturer of LED display frame, if it doesn't make great efforts in product R & D, it can't show high-grade effect. Industrial aluminum profile is a common material in social production. It is widely used in aviation, construction, condenser, automobile parts and LED application products. LED display aluminum profile has a wide range of applications, and its market share has reached a high share. It has become an important new material for the frame of LED advertising display screen. This is also bringing new business opportunities to the development of LED display supporting equipment manufacturers. GEKO gold frameThe surface of the traditional LED display frame is a conventional black electrostatic powder spraying process. Through the R & D and process improvement of LED display frame enterprises in recent years, electrophoretic silver and electrophoretic gold frames have been introduced in the market, which changes the situation that the LED display frame used only black in the past. It has formed differentiation in appearance, improved the grade of products, and received good feedback from end users. In addition to color, there are also many innovations in product structure. For example, a number of products newly developed by Jike application have won national patents, widely praised by the market, and have made good achievements in the field of LED display supporting products.In the field of LED display matching, connector is a small and precise device, and its quality is the focus of LED display matching equipment manufacturers. There is no absolute advantage in the connector industry at this stage. Connectors can also achieve high-end adaptation in some subdivided fields. Due to the different needs of each customer, the LED display supporting production enterprises have developed private customized products by using the company's professional R & D team according to the market demand. Through the R & D and production of supporting enterprises, it can save about 5% of the cost for display enterprises in the current competitive market. Moreover, through technological innovation, these connectors realize board to board link, which greatly facilitates the disassembly and assembly process of LED display. In recent years, led rental display screen has sprung up. These technological innovations have effectively solved the problems of inconvenient installation and difficult maintenance. This is also the future development direction of the connector.The above conclusion is that the LED industry is developing rapidly, and there are countless large and small LED display manufacturers in China. This situation of oversupply gradually highlights the cruel face of industry competition. The fall of some LED manufacturers in recent years indicates that the LED industry will face a major reshuffle again. Of course, if we want to improve efficiency in production speed, we must have technology as a strong backing. The future development trend of LED supporting field will be more and more convenient.When the market competition situation is not optimistic, win the market of product R & D and innovation peers with speed, such as battlefield and the law of the jungle. The success of an enterprise, in addition to having a correct development direction, must have a certain core competitiveness. In order to maintain competitiveness and occupy market share in the same industry, enterprises must constantly develop new products and quickly push them to the market to meet the changing market demand. If new products cannot successfully occupy the market, enterprises will lose market share and eventually lose profitability and competitive advantage.

How to Judge the Quality of Huge LED Display Screen, Three Key Words and Technical Indicators
How to Judge the Quality of Huge LED Display Screen, Three Key Words and Technical Indicators
The epidemic in the United States is still "burning", and there is no slowing trend at all. However, in order to restart the U.S. economy, the U.S. NBA professional basketball game opened again in the early morning of July 23. On the first day, eight basketball teams from the United States participated. Due to the epidemic, the basketball game has been postponed for a long time, and some star players have all arrived. This is an empty game. In order to create a lively atmosphere for the audience, the careful staff also arranged a number of huge LED display screens on the stadium to let the photos of the fans appear on the display screen, so as to make it easier for the on-site players to participate in the game.After watching the whole NBA warm-up game, there are really few highlights. On the contrary, I feel that an NBA game is not as good as China's CBA game. First of all, players may not play basketball for a long time, and the state of the court game is very general. The court layout can be described as poor. The court space is relatively small, which is very different from the regular NBA home court. In addition, the biggest hard injury to the layout of the whole stadium is the huge LED display screen.In order to create an atmosphere for players to play in the stadium, the staff set up a huge LED display screen at the edge of the stadium. When players play, the huge LED display will beat the slogan of NBA semi-finals, and there will be pictures of fans applauding and cheering. This is cloud refueling. Players complete a layup. It is strange that the huge LED display screen of the stadium plays the cheering scenes of other teams, which is really embarrassing. We can see the importance of a high-quality huge LED display screen.The use of the huge LED display screen of Riad smart display improves the on-site experience of the fans, and the use of the new scoreboard can easily improve the level of the venue. At the same time, the LED display screen has many functions, such as wonderful moment capture, strange lens playback, real-time live broadcast synchronization, competition information broadcasting, timing and integral statistics, advertising broadcasting, etc. coupled with perfect picture quality and sound equipment, it makes the scene more competitive atmosphere and shocking.Nowadays, events have been held more and more frequently in large and small stadiums, and the quality of LED display screens installed in related stadiums is particularly important. To judge the quality of huge LED display screen, we need to look at the technical indicators of three major keywords. They are flatness, viewing sight distance and high pixel.1. The flatness of LED display screen, local unevenness of the screen body, dead angle in viewing angle, or stretching and fracture of the screen. The simple method is to place the side of the long steel ruler at any position on the screen of the display screen, and measure the gap between the side of the steel ruler and the screen of the display screen with a feeler gauge.2. Viewing sight distance: the gymnasium should pay attention to the installation of LED display screen. The distance between spectators and display screen in the venue should meet the sight distance of most spectators. The sight distance of LED display screen is about the distance that the audience can see the characters of LED display screen clearly under normal conditions.3. With high pixels, the pixel out of control rate of the display screen of domestic and foreign stadiums (indoor and outdoor stadiums, large and small comprehensive stadiums) shall not be greater than two thousandths, and shall be distributed discretely. In order to eliminate picture particles, avoid moire lines during shooting and make the broadcast picture clearer, high pixels of LED display screen are required.fqj
Explanation of Common Terms of LED Display Screen
Explanation of Common Terms of LED Display Screen
1. LED brightnessThe brightness of LED is generally expressed by luminous intensity, and the unit is candela CD; 1000ucd (micro candela) = 1 MCD (millicandela), 1000mcd = 1 CD. The light intensity of a single LED for indoor use is generally 500ucd-50 MCD, while the light intensity of a single LED for outdoor use is generally 100 mcd-1000 MCD, or even more than 1000 MCD.2. LED pixel moduleThe LEDs are arranged into a matrix or pen segment and prefabricated into standard size modules. 8 * 8 pixel module and 8-character 7-segment digital module are commonly used for indoor display screen. The outdoor display pixel module has 4 * 4, 8 * 8, 8 * 16 pixels and other specifications. The pixel module for outdoor display screen is also called collecting tube bundle module because each pixel is composed of more than two LED tube bundles.3. Pixel and pixel diameterEach LED light emitting unit (point) in the LED display screen that can be individually controlled is called a pixel (or pixel). Pixel diameter refers to the diameter of each pixel, in millimeters. For indoor display screen, generally one is a single LED with a circular shape. There are 3.0, 3.75, 5.0, 8.0 and so on, among which 3.75 and 5.0 are the most common. In the outdoor environment, in order to improve the brightness and increase the sight distance, one pixel contains more than two cluster LEDs; Since more than two cluster LEDs are generally not circular, the pixel diameter of solid outdoor display screen is generally expressed by the average distance between two pixels: 10, 11.5, 16, 22, 25.4. Point spacing, pixel density and information capacityCenter distance or dot pitch of two pixels of LED display screen; The number of pixels per unit area is called pixel density; The amount of display content per unit area is called information capacity. The essence of the three is to describe the same concept: the point spacing reflects the pixel density from the distance between two pixels, and the point spacing and pixel density are the physical properties of the display screen; Information capacity is the unit of information carrying capacity of pixel density. The smaller the point spacing, the higher the pixel density, the more information capacity, and the closer the distance suitable for viewing. The larger the point spacing, the lower the pixel density, the less the information capacity, and the farther the distance suitable for viewing.5. ResolutionThe number of rows and rows of LED display pixels is called the resolution of LED display. Resolution is the total number of pixels of a display screen, which determines the information capacity of a display screen.6. LED panelThe LED pixel modules are assembled and arranged into a matrix according to the actual size, and equipped with special display driving circuit, DC regulated power supply, software, frame and external decoration to form an LED display screen.7. GrayscaleGrayscale refers to the degree of light and shade change of pixels. The grayscale of a primary color generally has 8 levels to 1024 levels. For example, if the gray level of each primary color is 256, the display color of the dual primary color screen is 256 256 = 64K color, also known as 256 color display screen.8. BicolorNowadays, most color LED displays are dual primary color screens, that is, each pixel has two LED tube cores: one is red tube core and the other is green tube core. When the red light tube core is on, the pixel is red, when the green light tube core is on, the pixel is green, and when the red and green tube cores are on at the same time, the pixel is yellow. Red and green are called primary colors.9. Full colorRed green double primary color plus blue primary color, three primary colors constitute full color. Because the blue tube and pure green tube core constituting full-color are more expensive, there are relatively few full-color screens at present.
As for the Size of LED Display Screen, Can It Be Enlarged at Will
As for the Size of LED Display Screen, Can It Be Enlarged at Will
prefaceThe LED display box has self-determined size, high structural strength, good flatness and easy splicing. Generally speaking, the size of Maipu Guangcai LED electronic screen will not be limited. So, can the size of LED electronic display really be enlarged at will? In fact, it can not be tolerated. We can explain it from the following aspects.01. Price and cost of LED displayAs for the price of electronic screen, the price of LED screen was maintained at 351 square meters several years ago. With the more extensive use in the past two years, the price is now almost maintained at 7000 or 8000 per square meter. Of course, this includes its steel structure, accessories, control card, computer, and so on! Generally speaking, it can be infinitely enlarged, but because of this price, most users can't afford it.02. Visual viewing effectThe farther the display is viewed, the larger the screen must be. Similarly, the closer the viewing distance, the smaller the screen must be. For example: our common indoor LED display screen, under normal circumstances, the viewing distance is a few meters. If it is far, it is at most 20 or 30 meters. Therefore, the area of indoor screen will not be too large, and most of them will be kept within 60 square meters. For the LED outdoor display screen, the viewing distance will be relatively far, generally from more than ten meters, so the area of Maipu brilliant display screen will be relatively large, usually within 10-100 square meters.03. Installation location and environmentThere is no doubt that the indoor environmental space location is relatively limited. For those outside the room, if there is not enough space and position to support, any screen of the display screen will be subject to relatively large nature, so the screen can be enlarged at will here.04. After sales serviceOf course, there is also a major problem that can not be ignored, that is, when the Maipu brilliant LED electronic display is enlarged at will, the after-sales service will become more and more difficult. Once a problem occurs, the relevant maintenance and troubleshooting is quite troublesome, which is a huge test in terms of manpower, money and time.fqj
How Can the Heat Dissipation of LED Display Screen Be Improved
How Can the Heat Dissipation of LED Display Screen Be Improved
In practical application, improving the heat dissipation of LED display screen can not only effectively improve the efficiency of heat dissipation of LED display screen, but also save power, which is more conducive to improving the service life of LED display screen.1. It is a common method to use a long-life and high-efficiency fan to strengthen heat dissipation inside the lamp shell. This method has low cost and good effect.2. Aluminum cooling fins are the most common way of heat dissipation. Aluminum cooling fins are used as part of the shell to increase the heat dissipation area.3. Aerodynamics, using the shape of the lamp shell to produce convective air, which is the lowest cost method to strengthen heat dissipation.4. Surface radiation heat dissipation treatment: the surface of the lamp shell is treated with radiation heat dissipation. The simpler thing is to apply radiation heat dissipation paint, which can bring the heat away from the surface of the lamp shell by radiation.5. Integration of heat conduction and heat dissipation -- the application of high heat conduction ceramics. The purpose of heat dissipation of lamp shell is to reduce the working temperature of LED HD display chip. Because the expansion coefficient of LED chip is very different from that of our common metal heat conduction and heat dissipation materials, the LED chip cannot be directly welded to avoid high and low temperature thermal stress damaging the chip of LED display.6. The heat conduction tube is used for heat dissipation, and the heat is guided from the LED display chip to the shell heat dissipation fin by using the heat conduction tube technology.7. The thermal conductive plastic shell is filled with thermal conductive materials during injection molding of the plastic shell, so as to increase the thermal conductivity and heat dissipation capacity of the plastic shell.It can be seen that the maturity and progress of LED display heat dissipation technology will be conducive to its concept of saving and environmental protection. LED electronic display manufacturers have a variety of methods to improve the heat dissipation of LED display in the production of LED display. There will be different considerations according to the power and place of use.
