Infrared touch screen technology principle:
Infrared touch screen is a highly integrated electronic line integrated product. The infrared touch screen contains a complete integrated control circuit, a set of high-precision, anti-interference infrared transmitting tubes and a set of infrared receiving tubes, which are installed in two opposite directions on a highly integrated circuit board, forming an invisible of infrared light. The infrared radiation array densely distributed in the Y direction is used to detect the user's own mode. In the infrared touch screen, a circuit board is installed in front of the display. The external circuit board arranges red line transmitting tubes and infrared receiving tubes on the four sides of the screen, corresponding one to one to form a cross infrared matrix. When the user touches the screen, the finger will block the direction of the external system passing through the position. The change in the light signal causes the electrical signal output by the photoelectric detection circuit to change. By processing the electrical signal, the position of the touch point on the screen can be located. , any touch object that is opaque to infrared light can block infrared rays to achieve touch positioning.
