1. An electronic device, comprising:
a display layer including a plurality of scan lines, a plurality of data lines, and a plurality of pixels;
a display driver configured to drive the display layer and provide a grayscale voltage to the plurality of data lines and is configured to provide a scan signal differently in different modes of operation;
a sensor layer disposed on the display layer; and
a sensor driver configured to be synchronized with the display driver to drive the sensor layer, wherein the sensor driver is configured to operate in a first sensing mode and a second sensing mode and wherein:
in the first sensing mode, the sensor driver is configured to sense an input through the sensor layer based on a first timing, and
in the second sensing mode, the sensor driver is configured to sense an input through the sensor layer based on a second timing different from the first timing, and
when the sensor driver is driven in the second sensing mode, the grayscale voltage is provided to the plurality of data lines and one or more of the plurality of pixels are not charged with a voltage corresponding to the grayscale voltage.
