CarrollTouch Infrared Touch 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.

Elo’sCarrollTouch infrared touchscreensprovide optical sensor technology for applications in harsh or glass-free environments. The next-generation design features a low-
profile 4.5 mm bezel with nearly pixel-level touch resolution and no parallax, and operates in extreme temperature, shock and vibration, and lighting conditions. The display is
protected by a choice of glass or acrylic overlays optimized for optical clarity, security, or safety. With their optical sensors, the CarrollTouch touchscreens provide stable, drift-free
operation, and deliver an extremely sensitive, accurate touch response. CarrollTouch touchscreens are the ideal choice in many industrial automation, transportation, and in-vehicle applications, POS terminals, and medical equipment.
