Abstract: A display device includes a display panel and an input sensing panel. The input sensing panel includes pluralities of first and second sensing electrodes and electrostatic induction patterns, each of which is connected to a sensing electrode from one of the pluralities of sensing electrodes and overlaps another sensing electrode from the other one of the pluralities of sensing electrodes. The input sensing panel includes a first area where deviations of mutual capacitances between the first and second sensing electrodes are small and a second area where the deviations are large. The electrostatic induction patterns include first electrostatic induction patterns disposed in the first area and second electrostatic induction patterns disposed in the second area, the second electrostatic induction patterns having a different area from the first electrostatic induction patterns, or the number of second electrostatic induction patterns being different from the number of first electrostatic induction patterns.

Abstract: An electronic device includes display driver and a sensor driver. The display driver drives a display layer and provide a grayscale voltage to a data lines. The sensor driver is synchronized with the display driver to drive a sensor layer, and operates in a first sensing mode and a second sensing mode. In the first sensing mode, the sensor driver senses an input through the sensor layer based on a first timing. In the second sensing mode, the sensor driver senses an input through the sensor layer based on a second timing different from the first timing.
