LCD screen itself has problems. If it is indeed the screen itself that is at fault after testing with relevant instruments, in addition to replacing a new LCD screen, the device-related software should be debugged and optimized so that the screen can work with the motherboard's CPU. The best way is to increase the OSC frequency of the IC and see how the LCD screen flickers. Of course, if the TFT LCD screen has separate row and column drivers, you can also adjust it by setting the driver chip.

Some customers are still not very clear about the resolution of the display screen. We will explain it here. The resolution of the LCD screen refers to the number of pixels of the LCD screen, that is, the number of dot matrix, which is usually the number of pixels in the horizontal direction multiplied by the number of pixels in the vertical direction. Under the same LCD screen size, the higher the resolution dot matrix, the clearer and more delicate the display image effect is.
