Abstract: Disclosed is an electronic device which include a display layer that includes a plurality of pixels, a sensor layer disposed on the display layer and includes a plurality of first electrodes and a plurality of second electrodes, a display driver that drives the display layer, and a sensor driver that drives the sensor layer and selectively operates, in a proximity sensing mode, in a first mode or a second mode different from the first mode. When the electronic device enters the proximity sensing mode, the display layer operates in an active period during which data are received from the display driver and a blank period during which the data are not received. The sensor driver operates in the second mode in a period overlapping the blank period.
