Color distortion is another common problem with LED displays. You may find that the colors displayed on the screen deviate from the actual colors, or the colors are too bright or dull.

There are several main reasons for color distortion. 

One is the signal transmission problem. If the signal is interfered during transmission, or the transmission line is of poor quality, it may lead to the loss or distortion of color information, resulting in color distortion.

 The second is the calibration problem of the display. If the display is not properly calibrated, or the calibration parameters are not set properly, it can also lead to color distortion.

Third, the influence of environmental factors. For example, the light intensity, temperature, humidity and other factors of the surrounding environment may have an impact on the color performance of the display.

To solve the problem of color distortion, first ensure the stability of signal transmission. Choose a good quality transmission line to avoid signal interference. At the same time, the display should be calibrated regularly, and the calibration parameters should be adjusted according to the actual use of the environment and demand, in order to obtain the best color performance. In addition, pay attention to control the surrounding environmental factors, try to avoid using the display in harsh environments such as bright light, high temperature, high humidity and so on.
