IR touch frame

A matrix of Infrared (IR) LEDs and photo diodes are used to create a two dimensional grid over the display to detect where infrared light is blocked and thus where touchpoints are. Toponetech' s available in both standard and custom industrial infrared touch screen sizes, Toponetech’s projected custom infrared touch screen forms, fit or function replacements for 3M™ and Elo™ touch sensors.

IR touch screen frame technology may not be new, but it remains a favorite. It tends to be employed in large-format displays and some kiosks and point-of-sale (POS) terminals. The custom touch screen display has a long life, furthering its popularity in the digital signage and interactive display markets.

Infrared touch technology requires a perimeter to be placed around the infrared touch screen. The perimeter consists of infrared LEDs placed on two sides of the IR touch frame and phototransistors placed on the opposing two sides. The two sides then work in pairs; the signal from the LED transistor is read by its opposing phototransistor. When that signal is interrupted, it indicates a blocked infrared beam, which, in turn, indicates a touch point. While most infrared custom touch screen display doesn’t require a touchscreen, a glass overlay usually is recommended in order to protect the underlying display.

1. Better performance for big infrared touch screen. Have good support on equipments sizes from 32” to 84”.

2.No restriction of touch medium No touch pressure required. Except for transparent medium, PIT supports all other touch mediums. Custom touch screen display with no touch pressure required. 

3. High image clarity. No transducers on the surface of the IR touch frame, keep the image details maximumly.

4. Excellent protection performance. Protection performance enhancements are optional: Waterproof, Anti-vandal.
