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: An electronic device includes a display device including a display panel, a touch panel, and a touch sensing circuit configured to sense a touch input. The electronic device also includes an input pen configured to provide, to the touch sensing circuit, information on intensity of pressure applied to the display device. The touch panel includes touch pressure sensors and signal lines connected to the touch pressure sensors. Each touch pressure sensor has an area per unit length that increases along an extended direction of each touch pressure sensor. Each touch pressure sensor has a resistance that varies with an intensity of pressure and an area of pressure applied to the touch pressure sensors.

Abstract: A display device includes a display panel and a touch panel. The touch panel calculates coordinate information of an input position by an electrostatic capacitive method in a first mode and calculates the coordinate information of the input position by an electromagnetic induction method in a second mode. The touch panel includes scan line groups and source line groups, which are operated as touch electrodes or touch coils on the basis of the operating mode thereof. In addition, the touch panel includes touch electrodes and touch coils, which are individually operated on the basis of the operating mode thereof.
