Patent ID: 8487911

Claim:
An image display apparatus with image entry function comprising: a plurality of pixel circuits disposed in a display region, each of said plurality of pixel circuits comprising a first pixel and a second pixel, each said first pixel containing a first photo sensor for receiving light irradiated from the observation side of the screen, and each said second pixel containing a second photo sensor continuously shielded from external light; a gate line extending in a first direction and connecting alternately to some of the first pixels and some of the second pixels; a plurality of first data lines extending in a second direction intersecting the first direction, each of the plurality of first data lines connects to some of the first pixels and disconnects to the second pixels; a plurality of second data lines extending in the second direction, each of the plurality of second data lines connects to some of the second pixels and disconnects to the first pixels, the plurality of the first data lines and the plurality of the second data lines are disposed alternately in the first direction; a sensor read line extending in the first direction and connecting alternately to some of the first pixels and some of the second pixels in a display region; a gate driver for applying a pixel select signal to the gate line; a data driver for supplying display data by way of the data line to the pixel selected by the pixel select signal; a sensor driver connected to the sensor read line; a first sensor signal processor circuit connecting to the plurality of first data lines and the plurality of second data lines; a plurality of first signal lines extending in the first direction, each of the plurality of first signal lines connecting to some of the first pixels and disconnecting to the second pixel; a plurality of second signal lines extending in the first direction, each of the plurality of second signal lines connecting to some of the second pixels and disconnecting to the first pixel; and a second sensor signal processor circuit connecting to the plurality of first signal lines and the plurality of second signal lines, wherein the first sensor signal processor circuit senses the secondary coordinates where the screen was touched based on the first photo sensor signal and the second photo sensor signal input by way of the plurality of the first data lines and the plurality of the second data lines.
