I.R Touch Display

Infrared touch technology (also known as I.R) is the most widely used touch screen in commercial applications and has been the industry standard for decades. Using I.R technology means that no actual contact with the screen is required so less damage is incurred over time. It works by embedding LED lights and sensors into the bezel of a monitor above the glass. These LED’s beam a signal across to the corresponding sensor on the other side forming an invisible grid. When the grid is broken by a finger, or other solid object, the sensors can detect the touch point. A bezel will always be required when I.R is used due to the way it works. There is no chance of edge-to-edge glass being used with IR. However unlike PCAP, IR technology can scale to very large sizes with no drop in quality.
