IR touchscreen 15″ or 21.5″

Brief Description:

General Touch’s IR touchscreens is a touch frame which is usually installed in front of the display screen. The infrared touch technology depends on the interruption of an infrared light grid. The frame is integrated with a PCB board which contains a row of infrared LEDs and photoreceptor on opposite side. Each of the infrared LED has a corresponding photo transistor set on the opposite end, creating a grid of invisible infrared light beams.

The bezel shields the electronics from the operating environment while allowing the IR beams to pass through. The controller sequentially pulses the LEDs to create a grid of IR light beams, A touch obstructs one or more of the beams which can identifies the X and Y coordinates.

This type of product have many benefits, such as unlimited stylus, high clarity and light transmission, no touch pressure required,  Reliable and durable without drift-off. It can be used in gaming machines, kiosk and banking machines.
