Patent ID: 7800602

Claim:
A light-sensitive display device comprising: a substrate having a light-sensitive region and a peripheral switch region; a scan line formed on the substrate; a read-out line formed on the substrate, the read-out line extending in a direction substantially perpendicular to the direction in which the scan line extends; a photosensitive switch located in the light-sensitive region and having a first end, a second end, and a control end, wherein the first end is electrically coupled to the scan line, the second end is directly electrically coupled to the read-out line, and the control end is directly electrically connected to the second end such that the photosensitive switch applies a light sensing signal to the read-out line in response to incident light when a bias voltage (V DD ) is applied to the first end; and a peripheral switch electrically connected to the scan line in the peripheral switch region.
