Abstract
A display apparatus includes a display panel that displays an image during a display period and detects a touch event during a non-display period. The display panel includes a plurality of common electrodes and a plurality of data lines capacitively coupled to the common electrodes during the non-display period. Coordinate information of a position at which the touch event occurs is calculated on the basis of a capacitance variation of the common electrodes and the data lines.
