touch screen monitor multiple displays.The infrared touch screen uses a dense infrared matrix in the X and Y directions to detect and locate the user's touch. The infrared touch screen is equipped with a circuit board frame on the front of the display. The circuit board arranges infrared transmitting tubes and infrared receiving tubes on the four sides of the screen, which correspond to the infrared matrix that crosses vertically. When the user touches the screen, the finger blocks the two infrared rays passing through the position, so that the position of the touch point on the screen can be determined. The external touch screen is a highly integrated electronic circuit integration 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. The two opposite directions installed on the highly integrated circuit board form an invisible infrared Raster. The intelligent control system embedded in the control circuit continuously pulses the diode to form an infrared polarization beam grid. When a touch object such as a finger enters the grating, the light beam is blocked. The intelligent control system will detect the change in the loss of light and transmit a signal to the control system to confirm the X-axis and Y-axis coordinate values.
