Talking about the anti - fatigue performance of RGB Color LED Display Modules products
    RGB Color LED Display Modules The anti-fatigue properties of the product depend on the production process. Poor anti-fatigue performance of the module made by the three  anti-treatment processes is difficult to ensure that the protective  surface of the circuit board will crack when the temperature and  humidity change.
    So the production process is also a key factor in determining the life of the RGB Color LED Display Modules. Display  production involved in the production process are: components storage  and pretreatment process, furnace welding process, three anti-treatment  process, waterproof sealing process. The effectiveness of the process and material selection and matching,  parameter control and the quality of the operator, the accumulation of  experience is very important, so a factory with many years of experience  in the production process will be more effective control.
 RGB Color LED Display Modules is a digital flat panel display, it has two ways to deal with video signals:
    The first: multimedia method, commonly referred to as a synchronous screen method. This method is to use ordinary multimedia card to capture TV signals, and mediation, filtering and tone separation. And then the video signal by A / D conversion, the MPEG encoding compression, in order to store. When we play it, it needs to be unpacked and then played directly on the computer monitor.
    Transmission  of large-screen signal is through a dedicated interface card from the  computer's DVI interface or graphics card obtained in the interface card  but also some processing. At  this time, the big screen is actually equivalent to the computer  monitor or part of it, usually called the window, you can achieve one by  one corresponding to the synchronous display. Since the computer monitor is scanned horizontally, the display  format of the large screen will be in the format of the monitor if the  transmission signal is not processed.
    The second: the use of special large-screen signal processor. It  is the interlaced scanning of the TV signal, processed into progressive  scan signal, and then in the RGB Color LED Display Modules on the play.  And  high-performance processing can handle up to 10 bits or more, in the  scan to do when the interpolation operation, motion prediction and  compensation, as well as scanning and so on. Now  large-scale RGB Color LED Display Modules also use this method, and  more image signal processing, trying to upgrade the signal to the  broadcast level, of course, the effect is better. Computer images have to go through this processor, and then transfer to the big screen display.
How to identify the RGB Color LED Display Modules brightness:
 1, DIY hand-made to facilitate the connection of light-emitting diodes 3V DC power supply, the best use of battery production. You  can use two button batteries, installed in a small plastic tube and  leads to two probes as positive and negative output, the end of the  shrapnel made directly with a switch, the use of positive and negative  probe corresponding to the contact with the light Negative pin, hold the end of the switch, the luminous tube was light.
 2,  followed by photoresistor and digital multimeter into a simple metering  device, the photosensitive resistor leads to two thin wires, directly  connected to the digital multimeter on the two test pen, multimeter  stalls on the 20K position (depending on the photosensitive resistor, Try to make the reading accurate), note that the measured value is  actually the resistance of the photosensitive resistor, so the more  light the smaller the value.
 3,  take a RGB Color LED Display ModulesLED light-emitting diode, with the  above 3V DC light, light head and close to the photosensitive resistor  connected to the photosensitive surface, this time, multimeter readings,  in order to distinguish LED Luminous brightness.
