Production process: After the module of the Best outdoor advertising LED screen in china has been wave soldered, the LED position has been fixed, and it should not be moved at this time. If the LED light is bumped during testing, repair, soldering, aging, and transfer. Even if the so-called LED light sorting is performed before the Best outdoor advertising LED screen is filled with glue, it is very easy to cause the lights on the LED screen to stagger irregularly, resulting in the color cast of the module.

Power supply problem: When designing the Best outdoor advertising LED screens, if a wrong judgment is made about what material to use (including the selection and amount of power supply), it is easy to cause problems in the power supply system of the LED screen, resulting in the color cast of the LED module phenomenon, etc. 
Control system and control chip: If the manufacturer of the Best outdoor advertising LED screen in china does not have the design, development, testing, and production capabilities of the LED display control system and control chip, then the quality of the produced display screen cannot be guaranteed. Once there is a problem with the control system and chip, it will not only adversely affect the color rendering of the module of the Best outdoor advertising LED screen in china, but also affect the overall performance of the display.
