In comparison, IR touchscreens don’t use an electrostatic charge to detect touch commands. Instead, they use a combination of light-emitting diodes (LEDs) and sensors to detect touch commands. IR touchscreens are designed with LEDs that emit light to corresponding sensors across the surface of the display. If you touch the display, you’ll disrupt the LED light in that area, which the device uses to detect your touch command."

Okay you were much faster than my initial google search results! I was going through articles to find out how these relate to ebook devices.
Thank so much for the explanation.
