1. An electronic device comprising:
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 crossing the plurality of first 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,
wherein, 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 for detecting an object 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 for detecting an object,
wherein when flicker is detected, the sensor driver selectively operates in the second driving mode of the second mode.
