Patent ID: 8026879

Claim:
A display device, comprising: a plurality of light emitting diodes (LEDs) forming a display of the display device; a driving circuit coupled to each of the LEDs, the driving circuit configured to drive each LED to emit light; and a sensing circuit coupled to each of the LEDs, the sensing circuit configured to sense an electrical signal from each LED when that LED is operated in a sense mode, wherein the plurality of LEDs includes first and second LEDs, and each of the first and second LEDs is electrically connected to the driving circuit and the sensing circuit, wherein the sensing circuit is configured to sense an amount of light incident on the first LED by receiving an electrical signal from the first LED, and the driving circuit is configured to drive the first LED in response to the amount of light incident on the first LED, and wherein the sensing circuit is configured to sense an amount of light incident on the second LED by receiving an electric signal from the second LED, and the driving circuit is configured to drive the second LED in response to the amount of light incident on the second LED.
