Patent ID: 8847935

Claim:
A display device comprising: a screen unit; a drive unit; a signal processing unit; and a selector, wherein the screen unit includes rows of scanning lines, columns of signal lines, pixel circuits forming a matrix, and a plurality of light sensors, the drive unit includes a scanner supplying a control signal to the scanning lines and a driver supplying a video signal to the signal lines, the pixel circuits are sectioned into plural pixel regions each having plural pixel circuits and a boundary, the pixel circuit emits light in accordance with the video signal, each of the plurality of light sensors resides within the boundary of a respective one of the plural pixel regions and outputs a luminance signal in accordance with the light emission, the selector supplies plural luminance signals to the signal processing unit by switching the signals, and the signal processing unit corrects the video signal in accordance with the luminance signals and supplies the video signal to the driver, wherein the plurality of light sensors arranged to correspond to the plural pixel regions are grouped into blocks by a given number of the plurality of light sensors, the signal processing unit processes the luminance signals by each block, wherein the display device further comprises a converter converting analog luminance signals outputted from the plurality of light sensors into digital luminance signals and supplying the signals into the signal processing unit, and wherein the converter is arranged to correspond to each block.
