Infrared (IR): Infrared touch screen technology is based on "legacy" technology. Infrared technology relies on the interruption of an infrared light grid in front of the display screen. IR touch screens provide good clarity, because they don't have the layers of plastic overlay. They allow the use of gloved hands or other triggering apparatus. In addition, they can meet ratings for NEMA 12/4 and Class I/II, Division 1/2 with purging.
In an infrared screen, miniature transmitters are located across two no opposing sides of the mounting bezel. The transmitters emit IR light beams from top to bottom and right to left with receivers located on the opposite sides to form a grid pattern across the screen. When an object, such as a finger or stylus, interrupts the beams, the x- and y-coordinates are detected.
Infrared touch screens are often used in manufacturing and medical applications because they can be completely sealed and operated using any number of hard or soft materials.
