    Abstract: A touch test device for a display device, includes a loading unit receiving a display device. The display device includes a touch sensing unit having driving electrodes and sensing electrodes. A touch driving circuit driving the driving electrodes and the sensing electrodes and detecting touch signal data for the driving electrodes, sensing signal data for the sensing electrodes, and touch data of touch nodes positioned at intersections between the driving electrodes and the sensing electrodes. A test processing circuit calculates parameter values inversely proportional to resistance deviations of the driving electrodes and the sensing electrodes, performs an arithmetic operation on the parameter values and the touch data of the touch nodes to provide corrected touch data, and detects defects in the driving electrodes and the sensing electrodes according to a result of comparing and analyzing the corrected touch data.

    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.
