2. What causes LCD display flash screen: The high frequency of the LCD screen itself leads to the flash screen.


The high frequency of LCD display leads to flash screen. In general, there are few problems of device flash screen caused by high frequency in real life. People's naked eyes have no flickering sensation for pictures over 60 hz, and the design standard of general LCD display is basically maintained on this data, so under normal circumstances, there will be no excessive frequency, but at the same time, the screen itself can not be ruled out. After testing by relevant instruments, it is really the fault of the screen itself. In addition to replacing the new monochrome LCD screen, the software related to the device is designed. The best way is to increase the OSC frequency of IC and see the flicker of LCD screen. Of course, if the LCD display has separate row and column drivers, it can also be adjusted by setting the driver chip to solve the problem of flash screen.

It is very common that the LCD display screen flickers when the frequency of the light source is close to that of the light source. Because of the different frequencies of the different light sources, it is also common for the LCD display screen to flicker when the frequency of the light source is close to that of the artificial light source. The best way to do this is to use an artificial light source or an LCD display device to avoid the occurrence of the flicker screen.
