Abstract: An electronic device includes a display layer that displays an image during a plurality of frame periods, a sensor layer, a sensor driving unit, and a main driving unit. When a user makes a call, the sensor driving unit switches from a first mode to a second mode and drives the sensor layer. When the sensor layer senses a large-area conductor in the second mode, the sensor driving unit switches from the second mode to a third mode and drives the sensor layer. When the main driving unit determines a proximity state in the third mode, the sensor driving unit switches from the third mode to the second mode and drives the sensor layer. When the sensor layer senses a touch in the second mode, the sensor driving unit switches from the second mode to a fourth mode and drives the sensor layer.

Abstract: A display device includes a display panel, a touch panel on the display panel, a host processor, and a display panel driver. The host processor receives proximity data of the touch panel. The display panel driver receives an input control signal from the host processor and drives the display panel based on the input control signal. The touch panel includes a proximity area and a non-proximity area. The host processor counts a rise of the proximity data in the proximity area to generate a first count value. The host processor resets the first count value when the proximity data in the non-proximity area increase.

Abstract: A display apparatus includes a touch panel including a plurality of electrodes and a touch driver. The touch panel includes first electrodes extending in a first direction and second electrodes extending in a second direction and overlapping the first electrodes. The touch driver is configured to drive the touch panel in a normal mode and a biometric information measurement mode. The touch driver is configured to sequentially apply a transmission signal to the first electrodes by shifting the transmission signal at each group of N electrodes (where N is a positive integer) in the normal mode, and to sequentially apply the transmission signal to the first electrodes by shifting the transmission signal at each group of Q electrodes (where Q is a positive integer greater than N) in the biometric information measurement mode.
