Since the advent of SCM in the 1970s, it has attracted people's attention and attention with extremely high performance price ratio, so it has been widely used and developed rapidly. The characteristics of single chip microcomputer are small volume, high integration, light weight, strong anti-interference ability, low environmental requirements, low price, high reliability, good flexibility and easy development. Because SCM has so many advantages, so its wide application field, almost to the point of penetration. In our country, SCM has been widely used in industrial automation control, automatic detection, intelligent instruments, intelligent household appliances, aerospace systems, national defense and military, sophisticated weapons, etc/

If the display card is broken or the display data line is in poor contact. That leaves the driver board and lamp aging. Take the display apart and pull out the screen cable to know whether the driver board is faulty or the lamp aging.
