    Abstract: An electronic apparatus includes a touch sensor, a driving circuit, and a switching circuit. The driving circuit includes a first detector and a second detector. The first detector transmits/receives an electrical signal to detect a position of a touch. The second detector transmits/receives an electrical signal to detect an intensity of the touch. The switching circuit selectively connects the first detector or the second detector to the sensor.

    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 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.
