Apple: Pixels as Touch Sensors for Brighter, Thinner Screens
Pretty neat Apple patent, Apple: pixels as touch sensors for brighter, thinner screens. "Apple's idea takes advantage of the faster switching of poly-Si to drive the pixels one instant, and use the capacitive properties of the individual pixels as touch sensors the next. The switching happens fast enough to give a clear, bright display, as well as responsive touch sensing. The elimination of the separate touch-sensing layer also makes for a thinner, lighter, brighter, and simpler touchscreen unit."
