Apple has won a patent (number 8207946) from the U.S. Patent & Trademark Office for a light sensitive display. It relates to touch sensitive displays.
Here's Apple's background on the invention: "Touch sensitive screens ('touch screens') are devices that typically mount over a display such as a cathode ray tube. With a touch screen, a user can select from options displayed on the display's viewing surface by touching the surface adjacent to the desired option, or, in some designs, touching the option directly. Common techniques employed in these devices for detecting the location of a touch include mechanical buttons, crossed beams of infrared light, acoustic surface waves, capacitance sensing, and resistive materials."
