Abstract: A display device includes a display panel including pixels, a touch panel including electrodes, a proximity sensor which is adjacent to the touch panel and detects proximity with respect to an object based on a capacitance variation, a display driver which drives the display panel and a touch controller which drives the touch panel and the proximity sensor. Here, the touch controller provides a negative voltage to the proximity sensor when the proximity sensor detects that the object approaches the proximity sensor such that a shortest distance from the object to the proximity sensor is equal to or less than a first reference distance.

Abstract: An electronic device includes display driver and a sensor driver. The display driver drives a display layer and provide a grayscale voltage to a data lines. The sensor driver is synchronized with the display driver to drive a sensor layer, and operates in a first sensing mode and a second sensing mode. In the first sensing mode, the sensor driver senses an input through the sensor layer based on a first timing. In the second sensing mode, the sensor driver senses an input through the sensor layer based on a second timing different from the first timing.
