What is the general reason why a LCD screen does not light up or display during use? If this problem occurs, we can investigate it from several aspects:
1. First, check the power supply fault of the LCD display screen
2、Secondly, there was an error in the LCD screen software initialization program.
3. Check the backlight of the LCD screen again to see if the light is burnt out by high current and if the resistance is false soldered. 4. Does the power supply meet the basic requirements of the LCD display module? If it is too high, it will burn out the LCD screen.
