panel display board.If infrared is used for a short distance, the degree of blocking can also be detected according to the attenuation of the received signal. This is the so-called simulation method. The simulation method uses a dense array of receiver tubes at the receiver and can also be used for contrast imaging. Pulse mode can be adopted, that is, the infrared transmitting tube transmits a signal of a fixed frequency, and the receiver only detects this frequency. The pulse mode has very strong anti-interference ability. The pulse method can also be used for digital communication if the signal is modulated at the operating frequency. This is the famous infrared communication. The remote control of household appliances, the infrared communication of computers, and even the fastest fiber-optic communication today. Infrared communication has no effect on the human body, and has a short transmission distance without space pollution. This chapter is designed to touch the screen, not to dazzle others, but from the prosperity of this family, we can also see that the infrared touch screen has a bright future.
