1. Control system
Control IC: Due to the fact that LED display screen manufacturers do not have the design, development, testing, and production capabilities for LED display screen control systems and control ICs. The produced display screen cannot be guaranteed, the only thing that can be done is to adjust various parameters.
Therefore, when the color deviation of the LED display module is caused by LED lights and production processes, the module can only be repaired or replaced. When it is a power supply issue, it is necessary to replace the power light, etc. If it is a problem with the control system and IC, we can only request the manufacturer to repair or solve it.
2. Production process
After the LED module has undergone peak soldering and the LED position has been fixed, it should not be moved again. But many companies, due to the lack of protective conditions, often collide and bend LED lights during testing, repair, welding, aging, and transfer processes. Then, before gluing, perform the so-called whole line, which can easily cause the lights on the LED screen to tilt irregularly, leading to module color deviation.
3. The problem with LED lights
Factors such as inconsistent chip parameters, defects in packaging adhesive materials, positional errors during crystal solidification, and errors during spectral separation can affect the emission wavelength, brightness, and angle of LED lights in the same batch. So, there is a very important process in producing LED electronic displays: mixing lights. Mix all LED lights of the same color evenly before inserting them onto the PCB. The advantage of doing so is that it can avoid local color deviation of the LED module.
4. Power supply issues
When designing LED display screens, it is difficult to have a clear idea of what materials to use (including the selection and amount of power supply), which may lead to problems with the power supply system and result in uneven power supply for LED modules.
