An electronic display apparatus includes a substrate, pixels and light
sensing parts. The substrate includes a display region and a peripheral
region adjacent the display region, and the substrate includes a
plurality of gate lines extended in a first direction and a plurality of
data lines extended in a second direction that is substantially
perpendicular to the first direction. The pixels defined by each of the
data and gate lines are formed in the display region to display an image.
The light sensing part is formed in the peripheral region, and the light
sensing part senses an intensity of an ambient light. The light sensing
part that senses an intensity of an ambient light is formed on the array
substrate, so that a luminance of the display apparatus may be adjusted
in accordance with the intensity of the ambient light.
