What is this technology?
CarrollTouch infrared technology is the survivor of harsh applications. It's the only technology that does not rely on an overlay or substrate to register a touch, so it's impossible to physically "wear out" the touchscreen. CarrollTouch technology combines superior optical performance with excellent gasket-sealing capabilities, so it's an excellent choice for harsh industrial and outdoor kiosk applications. Touched with a finger, gloved hand, fingernail, or stylus, it delivers a fast, accurate response every time. CarrollTouch infrared technology is available for flat panel solutions.

  How does this technology work?
The CarrollTouch infrared(IR) technology uses a small frame around the display with LEDs and photoreceptors on opposite sides, hidden behind an IR-transparent bezel.

The Controller sequentially pulses the LEDs to create a grid of IR beams. A touch obstructs one or more the beams which identifies the X and Y coordinates.
