Abstract
A display for providing information relating to an object relative to the display is disclosed. The display includes a plurality of pixels, and a plurality of light sensors. An individual light sensor of the plurality of light sensors is provided near an individual pixel of the plurality of pixels. An individual light sensor of the plurality of light sensors is configured to detect light. The information relating to the object relative to the display may be provided by correlating the amount of detected light from the plurality of light sensors to the information relating to the object.
Claims49
