Problems solved by technology

[0003] The defects of the above-mentioned technical scheme are: 1. The above-mentioned technical scheme is provided with a controller between the computer wiring and the display wiring, and realizes the time-limited use of the display by cutting off or connecting the computer signal. Teenagers who lack self-control ability only need to replace it again. A computer signal line without a controller can avoid time-limited control; 2. The above-mentioned technical solution does not include a communication module or a communication device, and cannot realize the linkage control of multiple screen display appliances. Teenagers can make full use of different screen display appliances to control the time difference. Continuous viewing, so that it is impossible to effectively limit the viewing behavior of young people, and it is impossible to effectively protect the eyesight of young people; 3. The above-mentioned scheme cannot realize the control of people's viewing distance
