Infrared touch screen
10.4" - 19" | CarrollTouch Elo TouchSystems

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.

Advantages

Because there is no overlay covering the display, the transmissivity of infrared touch systems is 100%.
There are no limitations on the type of material the stylus is made from.
Since the opto-electronics determining the touch location are fixed in one place, infrared touch systems are not subject to sensor drift. They need only to be aligned with the corresponding display.
Non-invasive scanning infrared touch systems can be easily attached to a display without disassembly
Scanning infrared touch systems can be sealed to NEMA 4 requirements, preventing water and dirt from penetrating the display electronics
