Abstract: A display device includes a display unit comprising a plurality of pixels. A touch sensing unit is disposed on the display unit and comprises a plurality of driving electrodes and a plurality of sensing electrodes. A touch driver supplies a touch driving signal to the driving electrodes through a plurality of driving lines and receives a touch sensing signal from the sensing electrodes through a plurality of sensing lines. During a first horizontal period of one frame period, the touch driver supplies a touch driving signal having a first pulse width to a first partial portion of the driving lines and supplies a touch driving signal having a second pulse width smaller than the first pulse width to a second partial portion of the driving lines that is different from the first partial portion of the driving lines.

Abstract: A display device includes pixels to display one or more images in display frame periods and sensors overlapping with the pixels. The sensors sense one or more user inputs in sensing frame periods that are shorter in duration than the display frame periods. A first sensing frame period includes a first non-sensing period that substantially entirely overlaps with a first display frame period. A second sensing frame period includes a second non-sensing period that overlaps with a portion of the first display frame period and a portion of a second display frame period. The first non-sensing period and the second non-sensing period have different durations.
