Patent ID: 7804493

Claim:
A display device, comprising: a plurality of pixels for generating a display image; a plurality of light sensors, wherein each light sensor is positioned near at least one pixel, and wherein each light sensor is configured to sense light; and a processor coupled to the light sensors configured to determine information associated with an object near the display device based on the light sensed by the light sensors, wherein the processor determines information associated with the light sensed by the light sensors by compensating for the effect of light emitted by the plurality of pixels, wherein the effect of the light emitted by the plurality of pixels is a lower light level being detected in a portion of the plurality of light sensors as compared with others of the plurality of light sensors; wherein the compensation is determined by subtracting the effect of the light emitted by the plurality of pixels; and wherein the effect of the light emitted by the plurality of pixels is a lower light level being detected in a portion of the plurality of light sensors as compared with others of the plurality of light sensors.
