摘要： A display device includes a display unit including pixels. A sensor unit overlaps with the display unit and includes sensors. A sensor driver transmits a driving signal to the sensors, and receives sensing signals corresponding to the driving signal from the sensors. One sensing period includes a first sensing period and a second period. The sensor driver transmits a first driving signal having a first frequency to the sensors in the first sensing period, and transmits a second driving signal having a second frequency different from the first frequency to the sensors in the second sensing period.

摘要： 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.
