Patent ID: 8373675

Claim:
A display apparatus comprising: a display panel comprising: an array substrate including a data line, a gate line crossing the data line, a first signal line substantially parallel to the gate line, a second signal line substantially parallel to the data line, a pixel including a pixel electrode and a common electrode insulated from the pixel electrode, a first sensing electrode electrically connected to the first signal line, and a second sensing electrode electrically connected to the second signal line; an opposite substrate combined with the array substrate to receive a liquid crystal layer and including a connecting member overlapping with at least a portion of the first sensing electrode and at least a portion of the second sensing electrode, the connecting member being connected to the at least a portion of the first sensing electrode and the at least a portion of the sensing electrode by an externally provided pressure; and a liquid crystal layer interposed between the array substrate and the opposite substrate and including liquid crystal molecules, of which an alignment is controlled by an electric field formed between the common electrode and the pixel electrode; a touch position detecting part detecting the first and the second signal lines electrically connected to the connecting member to output a detection signal; and a position determining part determining position coordinates of the externally provided pressure based on the detection signal.
