Infrared touch screen is the latest technology and it supports the most reliable touch technology. Our infrared touch screen consists of a touch frame which is installed in front of the display. The frame is integrated with a printed circuit board which contains a line of IR-LEDs and photo transistors hidden behind the bezel of the touch frame. The bezel shields the parts from the operation environment while allowing the IR beams to pass through.When touch is applied, the screen enters the gird by a stylus which can interrupt the IR light beams. The Photo transistors from X & Y axes detect the IR light beams which have been interrupted and transmit exact signals that identify the X & Y axes coordinates to the host. n
