How do touchscreens work Types of touchscreens compared ~ When you touch the screen you interrupt the sound beams and absorb some of their energy The screens microchip controller figures out from this where exactly you touched the screen A surfaceacoustic wave screen is a bit like an infrared screen but your finger interrupts highfrequency sound beams rippling over the surface instead of invisible light beams
