An electronic device includes a display layer configured to display an image, a sensor layer disposed on the display layer and including a plurality of first electrodes and a plurality of second electrodes, and a sensor driver configured to drive the sensor layer and selectively operate in a first mode or a second mode different from the first mode. When operating in the second mode, the sensor driver is configured to selectively operate in a first driving mode to simultaneously output a plurality of first transmission signals to the plurality of first electrodes or in a second driving mode to simultaneously output a plurality of second transmission signals different from the plurality of first transmission signals to the plurality of first electrodes.
