The infrared touch screen is a highly integrated electronic circuit product. The infrared screen contains a complete integrated control circuit, a high-precision, anti-interference infrared transmitting tube and a set of infrared receiving tubes, which are installed on a highly integrated circuit board. The two opposite directions form an invisible infrared grating. The dense infrared array in the X and Y directions is used to detect and locate the user's touch. The infrared touch screen installs a circuit board frame in front of the display. The circuit board Infrared transmitting tubes and infrared receiving tubes are arranged on the four sides of the screen, corresponding to a yellow and vertical infrared matrix. When the user fills in the screen, his fingers will block the infrared rays passing through the transverse direction of the changed position, and the light signal will change. Causes the electrical signal output by the photoelectric detection circuit to change. By processing the electrical signal, the point can be positioned at the desired position. Any object that is opaque to infrared light can interrupt the infrared ray to achieve touch positioning.
