Abstract
Official abstract text for this publication.
Disclosed is a display device. The display device includes a panel, a display driver IC, and a touch IC. The panel includes a plurality of driving electrodes and a plurality of sensing electrodes. The display driver IC outputs a common voltage to the driving electrode and the sensing electrode in a display driving interval, outputs a reference voltage to the driving electrode during a touch non-sensing period in a touch driving interval, and outputs a driving pulse to the driving electrode to receive a sensing signal from the sensing electrode during a touch sensing period in the touch driving interval. The touch IC transfers a control signal and a selection signal for selecting the touch sensing period and the touch non-sensing period to the display driver, and senses whether there is a touch with the sensing signal and the reference voltage.
