Patent ID: 7825894

Claim:
A display device for displaying images in response to image and control signals, comprising: a display surface through which input light is applied from an external object; a color filter having color pixels that are arranged to form a planar surface substantially parallel with the display surface; and a substrate having plurality of pixel portions respectively including a first switching member, and at least one light sensing portion disposed to face corresponding one of the color pixels, the at least one light sensing portion sensing light provided through the corresponding color pixel, wherein the corresponding color pixel is a red color pixel so that red light is provided to the at least one light sensing portion through the red color pixel, wherein the at least one light sensing portion includes: a second switching member controlled by the light provided through the corresponding color pixel, the second switching member generating a first signal in response to the light; a first sensing line electrically connected to the second switching member; and a third switching member controlled by a second signal provided via a gate line, the third switching member transferring the first signal from the second switching member to a second sensing line in response to the second signal.
