1. The control system is poor, the gray level is not high, and the scanning frequency is low 3. There is color difference in the mask, the brightness of the lamp is inconsistent, and the amount of waterproof glue will also affect the quality of the mask
if the above conditions appear on the LED display screen, it indicates that the quality of the connector used in the display screen is not up to standard. After checking and eliminating the cause of the fault, replace the relevant plug-in or the LED display screen. The LED electronic screen is composed of red, green and blue. The color difference you said may be a color deviation. You can test the single red, single green and single blue to know which color deviation it is. Basically, the three colors are controlled by the three white balance resistors on the unit board. You can see if the resistance value is the same as other modules, If not, it may be that two batches of modules are mixed for you, such as white balance resistor. It depends on whether the IC chips are the same. If they are all the same, it may be that the LEDs used are not of the same batch, so they are mixed for you
