The infrared touch screen used in the touch all-in-one machine uses the infrared matrix densely distributed in the X and Y directions to detect and locate the user's touch. The infrared touch screen is equipped with a circuit board outer frame in front of the display, and the circuit board is arranged with infrared emitting tubes and infrared receiving tubes on the four sides of the screen, corresponding to one by one into a horizontal and vertical cross infrared matrix.
When the user touches the screen, the finger will block the two vertical and horizontal infrared whiteboard lines passing through the position, so the position of the touch point on the screen can be judged. Infrared 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, which are installed in two opposite directions on a highly integrated circuit board to form an invisible infrared. Raster.
The intelligent control system embedded in the control circuit continuously pulses the diode to form an infrared polarized beam grid. When a touching object such as a finger enters the grating, the light beam is blocked. The intelligent control system will detect the change in light loss and transmit a signal to the control system to confirm the X-axis and Y-axis coordinate values.
