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.
Siemens Mp370 Touch Screen Replacement Experience
Siemens Mp370 Touch Screen Replacement Experience
In the afternoon of October 3, 2015, I received a phone call from the company's workshop saying that the paste making touch screen was black and could not be operated. Feel the scene, first use a multimeter to measure the power supply 24VDC, and confirm that the voltage of 23.7vdc is within the normal range. It is indeed the fault of the screen film, and the screen needs to be replaced.I arranged the workshop staff to go to the warehouse to find a mp370 screen with the same model but with a newer order number and version number to replace, install, connect, power on and prepare to download the program.I first found the last modified project file. The file version is winccflexible 2008 SP2. My laptop is already winccflexiable2008sp4. Opening the project file normally only prompts that it needs to be upgraded. Back up the old project file, and then select Yes to open the project file normally. Check each page respectively to confirm that it is consistent with the screen of on-site work.According to previous experience, first enter the touch screen control panel, check the s7transfer page setting parameters, select remote control, set the Ethernet IP address and return to the transmission state; Then adjust my notebook IP address to ensure that IP is different from the network segment, and Ping touchscreen IP address to ensure smooth lines.Select the project file, select menu transmission, check overwrite user management, check IP parameters, click download, the software compilation is completed and the download starts. After waiting about 20 seconds, a prompt "unable to connect the device, please check the line or parameter settings" pops up. This pop-up message does need to be checked if there are no previous preparations, but I don't need to check it now because it has been confirmed that the communication is normal and the device cannot be connected. It is estimated that the OS version is too different from the software in the computer.Select the project file, select OS update, and then a page will pop up to display the two connected computers. There is a lightning symbol on the middle connection, which is constantly moving back and forth. The text above indicates that it is "connecting". After a few seconds, it indicates that it is connected. Then the middle connection bulges a small packet and moves back and forth, and the text above indicates that it is "transmitting... *. Img"; At this time, look at the touch screen and start displaying file names one after another, indicating that OS system files are being updated at this time.After waiting for about ten minutes, the touch screen will restart automatically. After restarting, it will automatically enter the transmission page. At this time, the project file should be able to be downloaded. Select the project file, then select menu transmission, repeat the above transmission operation, and the same transmission page of OS update will pop up. Two computers have a connection, and the lightning in the middle will string back and forth for several times, and it will become a small drum bag and start transmitting the project file. After about 10 seconds, the project transmission is completed, and the touch screen will automatically enter the operation page.Click to open the page and find that the page display and operation are basically normal, that is, click the button and enter the text box, not on time, but oblique, indicating that the new screen needs to be corrected, and then start the fantasy journey of correcting the screen.
For the Size of LED Display Screen, Can Its Size Be Enlarged at Will
For the Size of LED Display Screen, Can Its Size Be Enlarged at Will
The 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

Process Analysis of LED Video Processor Processing the Display Effect of LED Display Screen
Process Analysis of LED Video Processor Processing the Display Effect of LED Display Screen
Video processor is the witness and landmark equipment for the birth, growth and maturity of full-color LED display. Today, led special video processing equipment is also gradually maturing in this process. The quality of LED video processor directly affects the display effect of LED display.In general, LED video processor is a special video processor for LED. The task it needs to complete, in short, is to convert the image signal from the outside (such as Blu ray DVD, computer, HD playback box, etc.) into the signal acceptable to the LED display screen. In this process, the LED video processor generally needs to complete the following processing processes:1 Resolution specification conversion: Generally speaking, the signal resolution provided by image signal sources (such as Blu ray DVD, computer, HD playback box, etc.) has fixed specifications (refer to VESA, ITU, SMPTE and other standards), while the modular splicing display of LED display makes its resolution almost arbitrary. The video processor converts various signal resolutions into the actual physical display resolution of LED display screen.2 Color space conversion: the color gamut of LED display is very wide, while the color space of most image signals is relatively small (such as NTSC). In order to make the LED display have excellent image display effect, color space conversion must be carried out.3 Bit depth improvement: at present, the gray level of LED display has been increased to 16 bits and 17 bits, but most of the input signal sources are only 8 bits. Therefore, following the arrival of the era of high-definition display, the application of 10 bit or even 12 bit processing technology in video processor has become a general trend.4 Zoom: in the process of resolution specification conversion, the image needs to be scaled. Whether the resolution is increased or decreased, the complete image can be displayed on the screen.
Apple Will Develop Display Screen and Develop the next Generation Microled on a Large Scale
Apple Will Develop Display Screen and Develop the next Generation Microled on a Large Scale
IPhone x is Apple's first mobile phone with OLED screen, and the screen of this mobile phone is provided by Apple's competitor Samsung, but this situation may change in the future.San Francisco - March 19, according to a reporter's report, Apple will independently design and produce its device display for the first time, and use the secret facilities near the California headquarters to produce a small number of screens for testing purposes.Apple hopes on the microled screen, which is different from OLED. The luminous compounds it uses are expected to make future devices thinner, clearer and more energy-saving. Apple is currently investing in the development of the next generation of microled displays.However, the production of microled screen is much more difficult than OLED. People familiar with the matter said that Apple almost gave up the project about a year ago, but the engineers made progress later, and the project was further developed. However, consumers may have to wait a few more years to see the research and development results.People familiar with the matter said that the scale of Apple's California factory can not meet the requirements of mass production, but the company hopes to prevent partners from obtaining this technology in the short term, and keep everything confidential in the development stage.The screen suppliers of iPhone come from manufacturers such as Samsung, Japan display and LG display. Apple's independent research and development of display components may turn these partners into competitors. However, mastering microled technology will also make apple stand out in the increasingly mature smartphone market.These insiders, who asked to remain anonymous because of the discussion of internal planning, said Apple was investing heavily in the development of the next generation of microled displays. The light-emitting compounds used by microleds are different from the current OLED displays, which is expected to make future devices thinner, clearer and more energy-saving.People familiar with the matter said that the production difficulty of this screen is much higher than the OLED display currently used. The company almost gave up the project about a year ago, but engineers made progress later. The technology has entered the later stage, but consumers may need to wait a few more years to see the results.This ambitious undertaking is the latest example of Apple's internalization of key component design. For several years, Apple has been independently developing chips to power mobile devices. In the long run, the R & D of display may hurt a series of current suppliers, such as display manufacturers Samsung, Japan display, sharp and LG display, and human-computer interface solution provider Synaptics. It could also hurt universal display Corp., a leading OLED technology developer.Mastering microled technology will help Apple stand out in the increasingly mature smartphone market and surpass rivals such as Samsung, which claims to have an excellent display screen. Ray soneira, who runs display mate technologies, a screen testing company, said that internal screen design was a "golden opportunity" for apple. "Everyone can buy an OLED or LCD screen," he said. "But apple can have microleds."None of this is easy. Mass production of new screens requires new production equipment. By the time this technology is ready, there may be other alternative technologies. Apple may encounter insurmountable obstacles and abandon or postpone the project. In addition, the investment in this project is also very high.Eventually, Apple may outsource the production of the new screen to minimize the risk of production chaos to its profits. A person familiar with the matter said that the scale of the California plant could not meet the mass production requirements, but the company would hope to prevent partners from obtaining the patented technology for as long as possible. "We invested a lot of money in the factory," the person said. "The scale of the factory is large enough to complete the engineering design. In the development stage, we should keep everything confidential."
What Is an OLED Display? This Article Teaches You to Understand the Difference Between LED Backlight
What Is an OLED Display? This Article Teaches You to Understand the Difference Between LED Backlight
LED backlight refers to the use of LED (light emitting diode) as the backlight of LCD, while LED backlight display is only the backlight source of LCD, which is transferred from traditional CCFL cold light tube (similar to fluorescent lamp) to LED (light emitting diode). The imaging principle of liquid crystal can be simply understood as that when the external voltage is applied to deflect the liquid crystal molecules, it will block the transmittance of the light emitted by the backlight like a gate, and then project the light into the color filters of different colors to form an image.The transition of backlight module from CCFL to LED can bring many benefits, which can make the brightness of the display screen more uniform, the product power consumption is lower, and the shape can be lighter and fashionable. However, w-led (white LED) backlight is widely used in the market. In fact, this backlight only replaces the luminous components, and the improvement of display effect is very weak or even not improved. Rgb-led (three color LED), which has significantly improved the display effect of LCD products, has significantly improved the display effect, but at the same time, the production cost is high, so it is applied to high-priced LCD TVs. At present, the LED display mentioned by businessmen refers to the display products with white LED backlight. The difference between it and ordinary LCD is the change of backlight.LED display screen integrates microelectronics technology, computer technology and information processing. It has become the most advantageous public display media with its advantages of bright color, wide dynamic range, high brightness, long service life, stable and reliable operation. At present, LED display screen has been widely used in large squares, commercial advertisements, stadiums, information dissemination, news release, securities trading, etc, It can meet the needs of different environments.LED display is a display mode by controlling semiconductor light-emitting diodes. Its general appearance is composed of many usually red light-emitting diodes, which display characters by turning on and off the lights. A display screen used to display text, graphics, images, animation, market, video, video signals and other information.OLED display is considered as the emerging application technology of the next generation of flat panel display because of its excellent characteristics such as self illumination, no backlight, high contrast, thin thickness, wide viewing angle, fast response speed, flexible panel, wide temperature range, simple structure and process.OLED is the abbreviation of organic light emitting diode, which is translated as organic light emitting diode or organic light emitting display. In fact, this luminescence principle was discovered as early as 1936, but it was not until Kodak launched OLED double-layer device in 1987 that OLED attracted people's attention as a commercializable and excellent flat panel display technology. At present, more than 100 research units and enterprises around the world have invested in the R & D and production of OLEDs, including display giants in the current market, such as Samsung, LG, Philips, Sony and so on. On the whole, the industrialization of OLED has begun, in which monochrome, multicolor and color devices have reached the level of mass production, and large-size full-color devices are still in the research and development stage, but the production capacity is still low.Many netizens are easy to associate OLED with the LED backlight hyped by current manufacturers. In fact, OLED and LED backlight are completely different display technologies. OLED emits light by driving the organic film itself through current. The light can be monochrome such as red, green, blue and white, and can also achieve full-color effect. Therefore, OLED is a new luminous principle different from CRT, led and liquid crystal technology.The LED display screen is composed of LED dot matrix and ledpc panel. The text, picture, animation and video can be displayed by turning on and off the red, blue, white and green LED lights. The content can be changed at any time. All components are display devices with modular structure. The traditional LED display screen is usually composed of display module, control system and power supply system. The display module is composed of a dot matrix composed of LED lamps, which is responsible for luminous display; By controlling the lighting of the corresponding area, the control system can make the screen display text, pictures, videos and other contents. Monochrome and two-color screens are mainly used to play text. The full-color LED display can not only play text, pictures, animation, but also play video and other formats.At present, it is widely used in every corner of the world because of its wide audience area, simple operation, long service life, energy conservation and environmental protection. In general, LED display, LED backlight and OLED are three completely different imaging technologies.
Common Faults and Troubleshooting of LED Display Screen
Common Faults and Troubleshooting of LED Display Screen
Unit board fault:A. The whole board is not bright1. Check whether the power supply is connected to the signal line.2. Check whether the test card can identify the interface. If the red light of the test card flashes, it will not be identified. Check whether the lamp board is connected with the power supply and ground of the test card, or there is a short circuit between the signal and ground of the lamp board interface, so that the interface cannot be identified. (smart test card)3. Detect whether 74hc245 has faulty welding or short circuit, and whether the corresponding enable (EN) signal input and output pin on 245 has faulty welding or short circuit to other lines.Note: mainly check the power supply and enable (EN) signal.B.

Detect whether the STB latch output terminal corresponding to 245 is connected with the latch terminal of the drive IC or whether the signal is short circuited to other lines.1. The display is confused and the output is abnormal1. Detect whether the clock CLK latch STB signal is short circuited.2. Detect whether the clock CLK of 245 has input and output.3. Check whether the clock signal is short circuited to other lines.Note: it mainly detects clock and latch signals.J. Display out of color1. Detect whether the data terminal of the color of 245 has input and output.2. Detect whether the data signal of this color is short circuited to other lines.3. Check whether there is open circuit, short circuit and faulty soldering at the cascade data port between the driving IC of this color.Note: it is easy to find the problem by using the voltage detection method to detect whether the voltage of the data port is different from the normal one and determine the fault area.K. There is a problem with the output1. Check whether the line from the output interface to the signal output IC is connected or short circuited.2. Check whether the clock latch signal of the output port is normal.3. Check whether the cascade output data port between the last drive IC is connected with the data port of the output interface or short circuited.4. Whether the output signals are short circuited to each other or to the ground.5. Check whether the output cable is in good condition.Full screen fault:The whole screen does not light up (black screen)1. Check whether the power supply is powered on.2. Check whether the communication line is connected and whether there is a wrong connection. (step by step screen)3. The synchronization screen detects whether the communication green light of the sending card and the receiving card flashes.4. Whether the computer monitor is protected, or whether the display area is black or pure blue. (step by step screen)The whole unit board is not lit (black screen)1. If several consecutive boards are not lit in the transverse direction, check whether the cable connection between the normal unit board and the abnormal unit board is connected; Or whether the chip 245 is normal.2.

???...My Laptop Display Screen Needs Cleaning...???
there are products available at computer stores, but they mostly are composed of alcohol and other agents, you can safely use Windex and a soft clothes to wipe the screen depending if its glossy or matt, be careful to not scratch the surface with a hard or coarse clothe. spray on the cloth and then wipe, if there are sticky smudge then try to get more windex on it but becaureful you dont get any inside the screen bezel.1. Suggest a mobile with bluetooth and big display screen?I prefer the itouch from apple.But the stereo sucks.Anyway the effects are cool too.You should have one2. Why is my monitor display screen too wide?Since you did not post what OS you are using, here are the instructions for windows XP. I think is similar for Vista and 7. First right-click on the desktop and then left click on Properties from the menu that appears. click on the settings tab at the top right of the box. Slide bar to change resolution. I think it's under personalize on Vista and 7.3. Where can I get a display screen with 30 Hz or less refresh rate? [closed]The information you are referring to is outdated. Flickering, banding, and other artifacts caused by refresh rate issues is primarily seen on CRT monitors -- LCDs are largely unaffected.If you want to reproduce this issue intentionally for the purposes of an experiment, you will probably need to find an old CRT monitor. The effects created by a monitor of this type cannot be reproduced accurately on an LCD4. My iMacs Display Screen Fell downYou have two distinct problems with your iMac that you are unfortunately conflating with the most obvious damage - the broken display. The display is most likely broken and will need to be replaced. I can be tested, but not in a typical home or office environment. The cable connectors on the logic board may be damaged as a fall like that will literally rip them off the board. A visual inspection should be enough to verify if they are good or notThe fan spin is likely because you replaced your hard disk with a non-Apple one that does not have a temp sensor. A missing sensor will cause the fans to spin at full speedThe slow performance is likely due to the erroneous temp readings (from the missing sensor) and the Mac thermal throttling in response. To fix the fan and speed issue, you simply need an inline temp sensor to send the correct data to the SMC. However, the screen is quite expensive and you should get a quote on a replacement prior to doing this - it may be much more cost effective purchase a replacement iMac of the same vintage and sell that one for "parts."Also, if you are going to replace a HDD and go through all the trouble on an iMac, you should spring for an SSD. The performance gains are well worth it5. My 1st generation iPod display screen is partially blank. Why?Try resetting it be shifting the hold button back and forth once and then holding the center and play button6. Why do people have to literally poke the display screen with their oily finger, can't they just glide over without touching it?I tried and it does not appear that way, no. The touch screen does not respond to gliding your finger near the screen, you have to touch it.Unless you are referring to a non-touch screen phone or computer where someone is just pointing and then touches the screen. I imagine that's because they misjudged the distance, or because they did not realize how oily their skin is7. Maytag Gemini Oven, the LOC on the bottom oven is on and the display screen shows F9-5, a?Maytag Oven F98. Where do I find a camera I can connect to a PC/Mac to display the screen of a cell phone?There is currently no adaptor on the market that can instigate your cell format through and into your Mac. It would take alot more than an adaptor to do such a thing. Yes you can go from your Digital camera to your Mac. But you can not go from your cell to your digital camera
