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.

Abstract: A display apparatus includes a first display substrate, a second display substrate, pixels, a scan line, a sensing line, a first driver, a second driver, and a coordinate calculator. The pixels include pixel rows and pixel columns. The scan line surrounds at least one pixel row of the pixel rows. The sensing line is insulated from the scan line and surrounds at least one pixel column of the pixel columns. The first driver applies a scan signal to the scan line and the second driver outputs a sensing signal provided from the sensing line. The coordinate calculator receives the sensing signal to calculate coordinate information. Each of the scan line and the sensing line is disposed on different layers from each other.
