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 device includes a display panel, an input sensor operating in an input sensing mode or a proximity sensing mode, a sensor controller driving the input sensor in the input sensing mode or the proximity sensing mode, and a main controller controlling driving of the sensor controller. The input sensor includes a sensing area and a non-sensing area. The sensing area is divided into a proximity sensing area and a plurality of reference areas in the proximity sensing mode. The main controller generates a noise control signal based on a plurality of reference sensing signals sensed in the reference areas, and determines whether an object is in proximity based on the noise control signal and a proximity sensing signal sensed in the proximity sensing area.
