Image Signal Processing of LED Display Screen
Image Signal Processing of LED Display Screen
There are generally two methods for processing image signals on LED display screen:One method is to use a special large screen signal processor to process the interlaced TV signal into progressive signal, and then play it on the large screen. The high-performance processor can process more than 10 bits. When doing scanning transformation, interpolation operation, motion prediction and compensation, scanning transformation and so on should be carried out. Now high-order large LED screens also use this method, and carry out more image signal processing, trying to improve the signal to the broadcast level, of course, the effect is also better. Computer images are also processed by this processor and then sent to the large screen for display. Processing technology is still developing, and many new algorithms have been proposed. This method is widely used in large-size back projection TV and plasma large screen TV, and the effect is much better than that of ordinary TV. In this case, the output signal is usually described according to the transformed signal format, which is more accurate.Another method is the multimedia method, commonly known as the synchronous screen method. This method uses an ordinary multimedia card to capture TV signals, demodulate, filter and separate timbre. After a / D conversion, the image signal is encoded and compressed by MPEG for storage. Decompress it when playing and watch it directly on the computer monitor. The signal sent to the large screen is obtained from the DVI interface or graphics card of the computer through a special interface card, and some processing needs to be carried out on the interface card. At this time, the large screen is actually equivalent to the monitor of the computer or a part of it, usually called window, which can realize one-to-one synchronous display. Because the computer monitor scans line by line, if the frame and line extraction processing is not carried out for the display signal, the display format of the large screen is the format of the monitor.For example, VGA format is a progressive scanning format with 640x480 pixels, and its scanning update rate is 75Hz. However, the 75Hz progressive scanning signal here is not the improvement of the image source itself, and the image quality has not been improved. In fact, it is worse than the standard of 50Hz interlaced scanning, similar to the effect of DVD or VCD, which is often confused. As for some screens, the screen is changed. For example, the even screen information is discarded and only the odd screen information is sent to display. Of course, the effect is worse. Incidentally, the situation of non video programs is relatively simple. Although some game animations also require good continuity, for animations played on the large screen, the picture update rate of more than 10Hz is acceptable.For the display screen controlled by the embedded controller or single chip microcomputer, the program is generated by the controller. Limited by the processing capacity of the controller, the speed of providing the picture is not fast enough, which will cause the picture discontinuity. The most typical phenomenon is that the bar screen controlled by single chip microcomputer is not smooth but jumping when the text moves left or right. Both experience and calculation show that if a bar screen composed of 10 16xi6 dot matrix Chinese characters wants to move the whole picture to the left at the speed of 5 seconds, its frame rate must reach more than 15Hz in order to move smoothly and coherently.
EMC Design and Improvement of LED Display Screen
EMC Design and Improvement of LED Display Screen
2012-2015 is the three years of rapid development of high-density LED display. It is predicted that the development of high-density LED products will go through three stages. The first stage is to enter the professional indoor large screen display market. In the second stage, it will enter the field of business conference and education and gradually replace the projector. The third stage is to enter the high-end home TV market. Limited by the technology of LCD TV, there is no technology in the field of large screen high-end household TV with more than 110 inches, and the projection technology is difficult to meet the requirements of high-end users for viewing effect. Therefore, small spacing LED display technology is expected to achieve brilliant results in this field in the future.Considering that the high-density LED display will gradually transition from the professional indoor field to the public indoor, and people's increasing demand for their own health and safety, the EMC design and certification related to health and safety is becoming more and more important. The EMC design and improvement of LED display can not be delayed.As we all know, LED is a low-voltage driven semiconductor light source. In the past, the AC-DC conversion and transmission of outdoor display screen were completed outdoors, which is far away from the crowd. When the high-density LED display screen gradually enters the indoor, we have to consider the accumulation of electromagnetic radiation in the limited space in this process.In order to deeply study the EMC of LED display, p2.5 display module of an LED display manufacturer is selected for relevant tests to verify our analysis and find the most effective design and improvement method for LED display EMC.According to IEC and CISPR standards, the sample test items are divided into EMI and EMS.The test results are as follows:(1) Test standard: en55022:2010 AC: 2011 / cispr22 (2008-09), en61000-6-3:2007 / a1:2011 / AC: 2012, test result: conducted interference.(2) Test standard: en55022:2010 AC: 2011 / cispr22 (2008-09), en61000-6-3:2007 / a1:2011 / AC: 2012, test result: emission interference.(3) Test standard: en61000-3-2:2006 / a2:2009, test result: harmonic interference.(4) Test standard: en61000-3-3:2013, test results: voltage fluctuation, flicker interference.(5) Test standard: en 61000-4-2:2009, test result: electrostatic discharge protection.(6) Test standard: en 61000-4-3:2006 a2:2010, test result: RF electromagnetic field protection.(7) Test standard: en 61000-4-4:2004 a1:2010, test result: transient pulse protection.(8) Test standard: en 61000-4-5:2006, test result: surge voltage protection.(9) Test standard: en 61000-4-6:2009, test result: conducted interference protection.(10) Test standard: en 61000-4-8:2010, test result: power frequency magnetic field protection.Because the LED display product itself adopts high-end switching power supply, is equipped with transient voltage suppressor and routing specification, it can be obtained from the test results that all tests except emission have passed smoothly. Therefore, emission has become a key problem to be overcome for LED display products to pass EMC certification. According to the previous measurement data, the switching power supply, control card and internal signal transmission of LED display screen will produce varying degrees of electromagnetic radiation. In addition, the working principle of LED display is to achieve high gray and high refresh by adjusting the parameters of current pulse on the LED. Therefore, the higher the refresh rate of the display, the higher the signal frequency on the system card, and the stronger the radiation interference. This is the inevitable result of the high-quality application of the display and one of the main electromagnetic disturbance sources of the display.The input and output lines of various signal cables and power input and output lines inside the display screen are densely distributed. The electromagnetic radiation generated by the switching power supply and the crystal oscillator on the control card will be coupled with each other among the internal cables to form a radiation channel, and finally transmitted to form conducted interference. This part of radiation is the most easily ignored part, but it is an important part of radiation emission, Therefore, the following measures can be taken for experiments.1 shieldingThrough the test, it is found that the signal connection flat cable between the module and the system adapter board is the key rectification object. At first, the spikes were suppressed by adding magnetic rings (see Fig. 1 and Fig. 2), but the effect was not obvious.It is really found that the length of the flat cable is significantly improved. When the system adapter board is used to load one module, the module output is cascaded with another module, and the noise value is only increased by 0.5 to 1dB. The system adapter board adds channels, that is, after carrying one more module, the noise value increases by 6 to 8dB. When the channel is increased, the length of the flat cable is 1.3 times that of the cascade, and the noise value is increased by more than 8 times. In addition, through data comparison, it is found that adding a magnetic ring at the power line has obvious noise suppression effect (see Fig. 1 and Fig. 3).2 filteringDuring the field test, a 3300uf electrolytic capacitor is added at the module power supply VH2. It is found that it has obvious inhibitory effect on radiation, especially on burr and energy spectrum in the range of 30MHz to 1000MHz (see Fig. 4 and Fig. 5). The larger the capacitance, the more obvious the inhibition effect on the burr peak, and the smoother the filtered curve. Of course, the selection of capacitance value needs to be determined according to the actual design requirements.3 formation shieldingWhen the adapter board is changed from the original 2-layer board to 4-layer board, that is, the grounding layers of the top layer and the bottom layer are added, which can also protect the circuit radiation.When two layers of grounding are added to the LED array driving board, the original 4-layer board is changed into 6-layer board, which can better prevent radiation. When the whole side of copper foil is attached around the adapter plate and fastened with the metal box with screws to form a shell ground, so as to shield the signal (Fig. 6).4 reduce the power supply voltage of the productBecause the value of conduction and radiation is directly proportional to DV / dt or di / DT, the higher the voltage, the greater the value of conduction and radiation. The power supply voltage of the sample is 4.6V. When the voltage is adjusted to 4.2V, it can be seen from the experimental data that the spike burr can also be improved (Fig. 7 and Fig. 8).5. Optimize product structureConsidering that the radiation is related to the maximum aperture size, the shielding effect can be greatly improved when the spacing of circular holes is much larger than the diameter of circular holes. Therefore, the heat dissipation joint of the rear cover was originally a long elliptical hole and then changed to a circular hole with a diameter of 4mm.6. Improve product processThe back cover of the original sample is an ordinary plastic part, which is improved to add a coating in the back cover. At the same time, it adopts plastic silver copper conductive paint, which is connected with the whole box through screws, so that the diagonal resistance measurement of the spraying surface is not greater than 20 ohms. Through such process improvement, it can also better protect the radiation.7 octaveBecause the gclck signal of LED display screen affects the refresh rate of the display screen, we can reduce it by changing the value of gclck. However, from the actual experiment, we find that the frequency doubling value has little effect. This improvement is not desirable in reality.8 conclusion

Small LED spacing is a general term for the distance between LED display lamp and lamp below p2.5. The smaller the spacing, the better the display, and the accompanying configuration will be higher. At present, led small spacing production technology is relatively perfect and popular, so there are many manufacturers of LED small spacing display screen for consideration.There are many manufacturers of LED small spacing display screens in Shenzhen. Similarly, there are many models of LED small spacing. Common models include: 0.9, 1.25, 1.56, 1.875, 2.0, 2.5... In addition to these common models, there are also some rare models that need bid control due to bidding.What are the characteristics of small LED spacing? Talking about this, we need to understand that as a branch of the display industry and the overlord of outdoor display, the highlight of LED display is that it can be displayed in height and continuity. Secondly, it also has great advantages in color and brightness. In the development of LED display screen, in addition to inheriting these main features, reducing the spacing and realizing more and more precise display, and slowly approaching the liquid crystal display is also the development trend of LED display screen, and the small spacing of LED is the result: high-precision display is realized, the display is more colorful and the performance is more powerful. You may not know it very well, but when it comes to LCD TV, it will certainly be familiar. When watching LCD TV, whether it is viewed from a close distance or from a remote place, we can't see that the display screen has a sense of granularity and won't feel uncomfortable. However, the LED display screen is different. Because it is composed of LED light beads, the distance between the light beads is too large, When viewing from a distance, the sense of granularity is very strong, and the smaller the distance, the sense of granularity will slowly disappear, while the p0.9 LED display screen can't see the sense of granularity when viewing within 2m.Generally speaking, the characteristics of small LED spacing are: good display, good color and high-intensity work. Of course, such functions as asynchronous control, multi screen display and multi rotation effect can be matched during configuration.Led small spacing as a more exquisite display, whether indoor or outdoor, the display is more outstanding. Moreover, due to the popularity of SMD technology, the price of LED small spacing is also very favorable.lw
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. In various electronic control equipment, digital display has become an indispensable and important link.

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

Unlock the 'Adapt Display' Screen Mode on Samsung Galaxy Devices for More Accurate ColorsAMOLED display panels like the one found in most Samsung Galaxy devices, including the Galaxy S6 models, are known for their deep blacks and vivid colors. The downside here is that the colors tend to be over-saturated and not very realistic. Samsung countered this issue by offering a "Screen mode" settings menu that you can use to adjust your display calibration. Of the four standard options that you will find in this menu, the "Basic" setting offers the most realistic color palette, but whites tend to be a bit yellow with this enabled. On the bright side, there's another option that has accurate colors and pure, crisp whites-but it was hidden from the default settings menu. Luckily, this hidden menu is incredibly easy to access, so your Galaxy device can have accurate colors in no time. Please enable JavaScript to watch this video. To access the hidden display calibration menu, you will need a launcher that is capable of creating activity shortcuts. (If you would rather not install a third-party launcher, an alternative method is shown near the end of this guide using the app More Shortcuts.) Head to the Google Play Store, then search for and install Nova Launcher. Once Nova is installed, press your device's home button, then select "Nova Launcher" from the list and press "Always." Next, long-press any empty space on your home screen, then select "Widgets" from the menu. From here, long-press the "Activities" icon, then drag it and drop it onto your home screen. At this point, a menu will pop up asking you to assign an activity to this shortcut. Scroll through the list and select "Settings," then tap the "ModePreviewTablet" activity to finish creating your shortcut. Next, simply tap the shortcut you just created to access the hidden display calibration menu. From here, deselect "Adapt display," then reselect it and press "OK." The new, more accurate display mode will be activated immediately, and to clarify, this is different than the "Adaptive display" mode that is already available in the regular settings menu. If you would rather not load up Nova to activate this hidden setting, you can access it using the More Shortcuts app from developer ChYK, which is a great app that we've covered in the past. Once installed, open More Shortcuts and select "Activity," then head to Settings and select "ModePreviewTablet." From there, simply deselect "Adapt display" and reselect it. With "Adapt display" mode activated, you should notice that the screen colors are a lot more accurate, and the whites do not have any yellowish tint. The mode will be disabled if you reboot your phone, but you can easily enable it again with the shortcut on your home screen or using More Shortcuts. How do you like your new display calibration setting? Let us know in the comment section below, or drop us a line on Android Hacks' Facebook or Twitter, or Gadget Hacks' Facebook, Google, or Twitter.
