IR 42 Inch Touch Screen Panel; Infrared Touch Screen Working Principle: Infrared Touch Screen panel is a touch frame which is usually installed in front of the 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 the touch frame. Each of IR-LEDs and photo transistors is set on the opposite sides to create a grid of invisible infrared light.

• IR 42 Inch Touch Screen Panel; Infrared Touch Screen Working Principle: Infrared Touch Screen panel is a touch frame which is usually installed in front of the 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 the touch 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 environment while allowing the IR beams to pass through. The Infrared Touch Screen controller sequentially pulses LEDs to create a grid of IR light beams. When a user touches the screen, enters the grid by a stylus which can interrupt the IR light beams, the photo transistors from X and Y axes detect the IR light beams
• which have been interrupted and transmit exact signals that identify the X and Y axes coordinates to the host. 1.
