Patent ID: 10809846

Abstract:
A display device includes a substrate, pixel electrodes, a display functional layer, common electrodes, first electrodes, and a controller. The common electrodes and the first electrodes intersect with each other. The controller controls the pixel electrodes, the common electrodes, and the first electrodes in a plurality of display periods to display an image, a first sensing period, and a second sensing period. During the display periods, the pixel electrodes are supplied with a pixel signal, and the common electrodes are supplied with a common signal. During the first sensing period, the common electrodes are supplied with a first drive signal to generate a magnetic field, and an electromotive force caused by the magnetic field is generated in the first electrodes. During the second sensing period, the common electrodes are supplied with a second drive signal to generate electrostatic capacitance between the common electrodes and the first electrodes.
