  •      Infrared Touch Screen Technology consists of infrared emitting and receiving sensing elements mounted on the outer frame of the touch screen. On the surface of the screen, an infrared detecting net is formed. Any touch object can change the infrared rays on the contacts to realize touch screen operation. 
  •  
  •      When there is a touch, the finger or other object will block the horizontal and vertical infrared rays passing through the position. When the touch screen scans and finds that there is an infrared light blocked, the red light is on, indicating that the infrared light is blocked, there may be a touch, and immediately change to another The coordinates are re-scanned. If another axis is found, there is also an infrared block. The yellow light is on, indicating that the touch is detected, and the position of the two infrared detectors that are blocked is reported to the host, and the position of the touch point on the screen is determined through calculation.
