Infrared Touch Panel Working Principal
IR Touch Screen is a touch frame which is usually installed in front ofthe display screen. The frame is integrated with printed circuit board which contains a line of IR-LEDs and photo transistors hidden behind the bezel of thetouch frame. Each of IR-LEDs and photo transistors is set on the opposite sides to create a grid of invisible infrared light. The bezel shields the parts from the operation
