On the Reasons for the Popularity of Small Spacing LED Display Screen

In recent years, the small spacing LED display screen in Zhengzhou, Henan Province has stood out among many display screens and occupied most of the LED screen market. Small spacing, as the name suggests, is that the point spacing of the screen is small and the resolution per unit area is high. The biggest competitiveness of indoor high-density LED display is that the display is completely seamless and the display color is natural and real. Usually, the distance between light beads is less than 2mm, so this display can display higher definition graphics, images and video, as well as more video and image images.

On the Reasons for the Popularity of Small Spacing LED Display Screen 1

So why are small pitch displays so popular? What's the secret of it? Today, let's learn what's great about the small spacing LED display.1. Ultra high definition, perfect picture quality, seamless splicing, exclusive visual feastThe splicing large screen display technology can not avoid the influence of the physical frame when meeting the needs of customers to the greatest extent. Even the ultra narrow side did professional LCD screen still has very obvious splicing seams. Only the LED display screen makes the splicing seams meet the seamless requirements, and the advantages of high-density and small spacing led seamless splicing are highlighted.

2. High brightness intelligent adjustableThe LED screen has high brightness. In order to meet the comfortable viewing effect for the viewer in strong light environment and dark light environment and avoid visual fatigue, it can cooperate with the light sensing system to adjust the brightness.3. High gray level for better color performance

Even under low brightness, the gray scale performance of the display screen is almost perfect, and the level and brightness of the display screen are higher than those of the traditional display screen. It can also show more image details without information loss.4. High contrast, faster response speed and high refresh frequencyThe number of times the electron beam repeatedly scans the image on the screen. The higher the scanning times, the higher the refresh rate, and the better the stability of the displayed image. The lower the refresh rate, the more severe the image flicker and jitter, and the faster the eyes get tired. Under high refresh, the LED small spacing screen has stable captured picture, no corrugated black screen, clear image edge and accurate restoration of the real information of the image

Technical Principle Analysis of Small Spacing LED Display Screen
Technical Principle Analysis of Small Spacing LED Display Screen
Small spacing LED display refers to indoor LED display with LED point spacing of p2.5 and below, mainly including p2.5, p2.083, p1.923, p1.8, p1.667, P1.5 and other LED display products. With the improvement of LED display manufacturing technology, the resolution of traditional LED display has been greatly improved.Today, we tend to take LED video display for granted. So do we know how the LED screen works? What is the principle of HD small spacing LED display? In fact, they become the common characteristics of our towns and us, mainly focusing on their external quality parameters.Five core technologies of small spacing LED display1. Reduce the dead light rate of the display lamp and ensure the stability of the screenThe dead light rate of the traditional LED display screen is one in tens of thousands in the industry standard, but the small LED display screen with small spacing can not be done temporarily. If there is one dead light in 10000 square meters according to the previous standards, the display screen can hardly be seen. Therefore, the dead light rate of small spacing LED display screen must be controlled at 1 / 100000 or even 1 / million in order to meet the needs of long-term use. Otherwise, if there are a large number of dead lights for a period of time, users can't accept it.2. Achieve low brightness and high grayMany people know that human body induction lamp is different from outdoor display, which requires high brightness, high refresh rate and energy saving. Indoor display needs to reduce the brightness. Experiments show that from the perspective of human eye sensitivity, the brightness of LED (active light source) is twice that of passive light source. In terms of specific data, the best brightness for small spacing led to enter the room is 200-400cd / m2. However, the gray loss caused by reducing brightness needs to be completed through technical supplement. At an exhibition of lianchengfa in 2016, the large screen display performance network released the test samples of small spacing led and gave the test methods and standards. The test shows that at present, only a few LED display manufacturers can achieve low brightness and high gray at the same time, and most manufacturers need to improve to a certain extent.3. Standard resolution of signal sourceUnlike the outdoor display, the outdoor advertising chamber of Commerce selects the content and display suitable for playback according to the resolution of the display screen. The indoor display signal source has certain standards. As a manufacturer of LED display screen, it is not required that the signal source connected to the indoor must adapt to the resolution of the display screen, but to adapt to the needs of the indoor signal source and design and ensure the corresponding resolution, So as to meet the needs of users as much as possible. Fortunately, after more than a year of understanding of indoor LED display products and customer needs, lianchengfa has completed this transformation and greatly met the needs of the majority of users.4. Support system access, display and control of multi signal and complex signalCompared with the outdoor display signal, the display signal of small spacing Lede display is characterized by multi signal access and complex signal access, such as multi place video conference, which requires remote access signal, local access signal and multi person access. The experiment shows that the simple implementation of multi signal access through excessive screen cutting scheme will reduce the signal standard. Therefore, how to solve the problem of multi signal and complex signal access also needs the technical support of small spacing led.5. Realize seamless joint and high-speed correctionThe biggest advantage of small spacing LED display is seamless, but it requires high splicing. For liquid crystal, as long as the seam is uniform, there is no problem, and the seam is not obvious. However, the small LED spacing can not be like this. If the modules are too tight, there will be bright lines. When the modules leave, there will be dark lines. So it's not easy to splice well. Therefore, the process and correction technology of the box and the guarantee and good combination of efficiency need to be guaranteed.Scanning mode of small spacing LED displayDynamic scanning: dynamic scanning implements "point to column" control from the output of driving IC to pixel points. Dynamic scanning requires control circuit, and the cost is lower than static scanning, but the display effect is poor and the brightness loss is large.Static scanning: static scanning implements "point-to-point" control from the output of driving IC to pixel points. Static scanning does not need control circuit, and the cost is higher than dynamic scanning, but it has the advantages of good display effect, good stability, small brightness loss and so on.With the development of LED technology, the brightness of LED electronic display screen is also increasing, and the size is becoming smaller and smaller, which shows that more LED small spacing electronic display screens will become the general trend.However, the improvement of brightness and pixel density of LED small spacing display also brings new and higher requirements to the control and drive of LED small spacing display. As far as the general indoor screen is concerned, the current common control methods adopt the row column split control mode, which is commonly referred to as the scanning mode. At present, the driving modes of LED small spacing display screen include static scanning and dynamic scanning. The static scanning is divided into static real pixels and static virtual, and the dynamic scanning is also divided into dynamic real image and dynamic virtual;In the LED small spacing display screen, the ratio of the number of rows lit at the same time to the number of rows in the whole area is called scanning mode. The scanning is also divided into several driving modes, such as 1 / 2 scanning, 1 / 4 scanning, 1 / 8 scanning and 1 / 16 scanning. In other words, if the driving mode of the display screen is different, the setting of the receiving card is also different. If the receiving card was originally used on the 1 / 4 scanning screen and is now used on the static screen, the display on the display screen will be bright every four lines. Generally, the receiving card can be set. After connecting the sending card, display screen, computer and other main devices, you can enter the relevant software on the computer for setting. Here we will first introduce the scanning mode and principle of LED small spacing display screen.Display principle of HD small spacing LED screenLED screen display resolution (so-called spatial resolution), which is closely related to the distance or pitch between pixels in LED video display;Maximum brightness of LED screen: the dynamic brightness range is understood as the number of brightness levels of the screen that can be supported (sometimes referred to as radiation or energy resolution);LED screen frame rate usually measures the frequency of frame change per second (FPS) (sometimes referred to as time resolution) of new data display that a video source can feed the whole frame;The number of LED screen refresh rate (in Hertz) is to draw data in the second display hardware, or refresh frame (also known as time resolution);Spectral resolution of LED screen: color images distinguish light of different spectra. Multispectral images solve even better than the need for different wavelengths of spectrum or copied colors. This word determines how many spectral components create an image; Color uniformity throughout the screen; Possibility of white balance and fine adjustment;Linear brightness sense of LED screen - subjective image quality, which determines the human eye to distinguish the dark and bright parts of the screen with adjacent brightness levels;LED screen image comparison; Image quality depends on the viewing angle. In addition to image quality, it is important to consider some key operating parameters of LED video display.The principle of high-definition small spacing LED display is briefly described; Mature software and integrated control system enable the system to expand and build led and LCD video display network and remote control through the Internet and built-in information security subsystem; The level of electromagnetic radiation is in the form of electromagnetic interference (EMI) from the screen.
The First Sill of Small Spacing LED Display Screen Entering the Room: "low Light and High Gray"
The First Sill of Small Spacing LED Display Screen Entering the Room: "low Light and High Gray"
Indoor small spacing LED is an emerging market, which is bound to face the lack of current industry standards, which causes many manufacturers to blindly launch products that do not meet the actual requirements. The market will follow the law of survival of the fittest, and users will be able to make the right choice. Low brightness and high gray is undoubtedly the first threshold for small spacing LED display to enter the room."Low brightness and high gray" is the threshold for LED entryIn the field of indoor display, most of the traditional LED displays are used for advertising display or information display. With the gradual maturity of small spacing LED display products, the application field of LED display expands rapidly. The commercial display, conference display, command and control, dispatching and monitoring covered by indoor display may become the market of small spacing led. This market may have a scale of tens of billions of dollars a year in the future.Facing the temptation of the market, LED display manufacturers swarmed in. Major LED display listed companies have successively released their small spacing LED products: Large-size "LED TV" of lyade, "led super TV" of Zhouming technology, LianJian photoelectric micro dense LED display "and so on. Although they have different names, they are essentially small spacing LED display screens. In addition to these listed companies, there are many companies optimistic about the indoor small spacing LED market and ready to test the water in the industry.Figure: 144 inch LED TV launched by RiadHowever, does the current specification of small spacing LED display meet the needs of indoor applications? Simply move the LED display directly from the outside to the inside? Great changes have taken place in the application environment of the products. The hot headed LED screen manufacturers need to think about whether the design of the LED display product itself also needs to be changed according to the application environment?Therefore, if a small spacing LED display with a nominal brightness greater than 1200 CD / is directly applied to the indoor environment, there are only two results: either high brightness damages the user's eyes, or reducing the brightness while losing the gray level and image quality, which are not the desired results of the user.To solve this problem, it is necessary for our display manufacturers to upgrade the current small spacing display screen and develop a small spacing LED display screen with "low brightness and high gray". The so-called low brightness and high gray is specifically explained as follows: when the brightness range of small spacing LED display screen is in the range of 100 CD / - 300 CD / , the gray level of the display screen is not lost, or the degree of gray level loss is within the range that is difficult to be perceived by human eyes.The characteristics of low brightness and high brightness of LED display screen are related to the chip, drive, control and other links of display screen. Therefore, display manufacturers need to devote themselves to research and development in order to make a display truly suitable for indoor environment applications. We are also pleased to find that small spacing LED displays with low brightness and high gray have appeared in the market. Among the products we tested, there are small spacing products with excellent performance. When the brightness reaches 100cd / or even below, the gray loss is difficult to distinguish with the naked eye, and the image quality restoration is very good.Therefore, low brightness and high gray is a threshold that led display manufacturers must cross to enter indoor display applications. Low brightness and high gray will be one of the key factors to distinguish the high and low quality of LED display with small spacing. For products with small spacing, the competition of LED display screen will no longer compare whose brightness is high, but whose brightness is low. Compared with whose display screen can reduce the brightness without losing gray and image quality. In other words, only the small spacing LED display with low brightness and high gray is a good product that meets the requirements of users and has competitive strength.Indoor small spacing LED is an emerging market, which is bound to face the lack of current industry standards, which causes many manufacturers to blindly launch products that do not meet the actual requirements. The market will follow the law of survival of the fittest, and users will be able to make the right choice. Low brightness and high gray is undoubtedly the first threshold for small spacing LED display to enter the room.One of the most significant differences between indoor and outdoor applications is the change of ambient light. When the LED display is used outdoors, the intensity of sunlight during the day is very high. Therefore, the brightness of the outdoor LED display needs to be highlighted, re lit and super bright! The higher the brightness of the display, the higher the technical specifications of the display.However, after the small spacing LED display screen enters the room, the application conditions have changed greatly: first, the brightness of the indoor environment is greatly reduced; Secondly, compared with the traditional users of LED display screen, small spacing LED products also quickly and greatly shorten the viewing distance between the display screen and users; Another notable feature is that users in indoor conference, command and control and monitoring rooms will continuously pay attention to the screen for a long time.Under the indoor dark environment, human eyes look at the high brightness small spacing LED display screen for a short distance and a long time. The unique high brightness of LED often makes people feel dazzling, and even causes eye pain, tears and reduced vision. Therefore, the brightness of LED display screen is too high, which will bring visual fatigue to users of indoor applications, and even cause irreparable eye damage! It can be said that the brightness of small spacing LED display screen is definitely not the higher the better. Its brightness must be reduced.

What They Don't Tell You About IPhone Screen Replacement
What They Don't Tell You About IPhone Screen Replacement
So you've watched the videos and looked at the photos of iPhone 3G disassembly and now you are ready for action. The glass screen is cracked and/or the LCD is broken and you have no intention of spending days without your device and paying Apple $200 or more. Although the do-it-yourself attitude is noble, it could cost you even more money if you are not careful. The tutorials above are a good start, but more details can only help. Take these tips to heart if you are going to fix the screen yourself.First and foremost do not ever buy the glass alone (typically $20). It's useless. The digitizer can not be detached from the front glass. The next best option is the front glass and digitizer together (around $60). The LCD is mounted with screws behind the digitizer and runs $80-90. Remember, you perform this repair at your own risk, and will render any remaining warranty invalid.1) Removal of all screws requires a 1.4 mm phillips screwdriver. Be sure the work area is free of dust and debris. One speck of dirt between the glass and LCD will annoy you forever.2) Use a plastic case opener or prying tool.You must push down on and stretch the black rubber seal that goes between the silver bezel and the glass. Best to damage it in only one spot directly above one of the screw holes near the home button. Razor blades or screwdrivers will not easily fit between the bezel and glass or exert pressure in the right place. It takes some depth to get under the glass and black plastic home button frame to lift it up. The glass can easily be cracked (or cracked worse) with the wrong tools or pressure.This could also result in glass particles flying directly into your eye.3) When removing the ribbon cables be sure that cable number 4 does not accidentally come off.4) Removal of the LCD from the front glass assembly requires care. Do not use the case opener tool to pry the LCD out of the metal frame after all 6 screws are removed. If necessary pull up with the tool on the metal backing of the LCD to lift it free. The easiest way to crack your LCD screen is to pry between the LCD and the front glass!5) When prying the black plastic home button frame from the front glass exert pressure from the inside of the frame to prevent further damage to the black rubber seal surrounding the glass. The plastic frame is attached to the glass and digitizer with adhesive. Be patient.The plastic frame is extremely fragile and can easily be broken along the corners or sides where it's thin.6) After the parts are disassembled remove all of the packaging materials and stickers from the new parts. Again be sure that all parts are dust, dirt and fingerprint free.7) Before you begin to reassemble the phone make sure the ribbon cable coming out of the new digitizer is oriented properly. It must be folded down into the body of the phone. There is another small black ribbon on the digitizer that can easily slip up into the SIM card tray slot. Make sure this ribbon is also folded downward into the unit as you reassemble.8) Some suggest double-stick tape to attach the new glass front piece to the black plastic home button frame.A few dabs of rubber cement will work well if you are patient enough to hold the assembly together while the glue dries.9) Take care when reattaching the ribbon cables. They are extremely delicate. Do not destroy your motherboard.10) Another fraction of a drop of glue on the screws will help to keep them from working lose. Mobile devices are subject to a lot of vibration and stress. The blue material on the screw threads served this purpose until the screw was removed.My 18 month old iPhone 3GS won't turn on. I had the screen replaced in apple store on tuesday and was advised?Take it back to the apple store I am guessing it isnt connected any more we got a new screen too and it did that get ask them to fix it cause they screwed up

Discussion on the Solution of Air Tightness Detection of Electric Bicycle Display Screen
Discussion on the Solution of Air Tightness Detection of Electric Bicycle Display Screen
Electric bicycle display screen is also called electric bicycle instrument panel. The display screen of electric bicycle generally displays the current battery power or battery voltage, vehicle speed, driving mileage and time, fault information, etc. you can see the operation of electric bicycle at any time. The internal circuit of electric bicycle display screen belongs to electronic products, and electric bicycles are generally used outdoors, often driving in the rain or parking outdoors.Therefore, the display screen of electric bicycle must have waterproof performance higher than IP67 waterproof and dustproof grade, so as to ensure that the display screen of electric bicycle can operate normally in any environment. Therefore, the manufacturer will test the air tightness of the instrument before leaving the factory. What is the solution for the air tightness test of the display screen of electric bicycle.The traditional detection method adopts the water detection method (bubble detection method), the result is very intuitive, but the detection accuracy and efficiency are low, and there are many electronic components in the electric vehicle instrument. If water enters the instrument, it will directly damage the internal electronic components, so the water detection method is rarely used. For electronic products, dry compressed air (which will not cause secondary damage to the product) is widely used as the detection medium to detect the air tightness of the display screen of electric bicycle. The detection instrument used in the air tightness detection solution of electric bicycle display screen is air tightness detector.According to the product shape, goer technology has made a profiling mold according to the product shape, and placed the product in the air tightness detection mold of the electric bicycle display screen.

How to Set the LED Display Screen to Play Regularly and Switch on and Off
How to Set the LED Display Screen to Play Regularly and Switch on and Off
Large LED display screen is a common information display window for organs, enterprises and institutions, which plays a more and more important role in life. How to realize the LED display screen timing play and on-off? To this end, Maipu Guangcai has something to say: we all know that if the display all day depends on people to turn on and off the computer regularly, it will be very tired and delay time, so it is very necessary to turn on and off the machine automatically and play it automatically.How to play LED display regularly:To control the playback time of the LED display screen, you need to use the "regular sending" function in the installed software. Maipu Guangcai prompts you here: first edit the display file, and then specify the sending file corresponding to the sending time. Due to different control card software, different functions and different use methods; If your software can't achieve this function, you can consider using the secondary development function of the control card to write your own timing sending software.How to automatically switch on and off the LED display at fixed time:1 BIOS setting fixed-point automatic power on every dayStep 1: start the L E D display server computer, press del to enter BIOS, then select "power management features" and 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 alarm date", press enter, and then set its value to "every day", indicating that the same operation is carried out every day. In the same way, set "RTC alarm hours", "rtcala RM Mi nut e" and "RTM alarm second" 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 mainboards is different, the settings of some mainboards may be a little different from those above, but just remember to find the words "wake up" or "resume by alarm" in power management, because this is the option to set timed power on.2 With the help of shortcuts, the display information file is automatically run after startupStep 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 right-click the "common. L e d" icon, click "properties", click the "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, click "create shortcut", and a "shortcut to common. Led" icon will appear. 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, and copy the "... Shortcut to common. Led. LNK" in the "open" column 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", paste "D: LED shortcut to common. Led. LNK" in the "command line", and set the title yourself.After this setting, the startup will automatically run the display file "common. Led", which has the same effect as manually opening "common. Led".fqj
