1. A display apparatus comprising:
a display panel that includes a first substrate providing a touch surface, wherein the display panel displays an image during a display period, and detects a touch event during a non-display period; and a touch sensor configured to calculate a coordinate information of a position at which the touch event occurs, wherein the display panel comprises:
a plurality of common electrodes that receive a reference voltage during the display period and receive sensing signals during the non-display period, the common electrodes being extended in a first direction; anda plurality of data lines that receive data voltages during the display period, the data lines being extended in a second direction crossing the first direction, and a portion of the data lines being capacitively coupled to the common electrodes during the non-display period. |
