Claim:
1. A display, comprising: an array of pixels including at least a first pixel in a first region of the display and a second pixel in a second region of the display; a plurality of photodetectors that detect ambient light including at least a first photodetector in the first region of the display and a second photodetector in the second region of the display, wherein the first photodetector generates a first ambient light signal in response to ambient light incident on the first region of the display and the second photodetector generates a second ambient light signal in response to ambient light incident on the second region of the display; and a controller that determines control signals for the pixels to compensate for differences in ambient light across the display, wherein the control signals include at least a first control signal that provides a first compensation to the first pixel based on the first ambient light signal and a second control signal that provides a second compensation to the second pixel based on the second ambient light signal, wherein the first compensation is different than the second compensation, and wherein the first and second photodetectors are each disposed between a respective pair of pixels in the array of pixels.
