Abstract: A display device includes: a first pixel connected to a first data line and a first scan line; a second pixel connected to the first data line and a second scan line; a first scan driver connected to a first scan start line and the first scan line; and a second scan driver connected to a second scan start line and the second scan line. In a first frame period, the second scan start line is to be suppled with a second scan start signal having a turn-on level, after a first period elapses after a first scan start signal having a turn-on level is supplied to the first scan start line. In a second frame period, a difference between a time at which the first scan start signal having the turn-on level is supplied and a time at which the second scan start signal having the turn-on level is supplied corresponds to a second period. The second period is shorter than the first period.

In a first initialization period, the data switch connects data lines to the data driver, which applies an initialization voltage thereto. In a first sensing period, the data switch connects the data lines to the ADC. The ADC receives analog sensing signals corresponding to first voltages of the data lines, and converts the analog sensing signals into digital sensing signals output to the controller. In a second initialization period, the data switch connects the data lines to the data driver, which applies the initialization voltage thereto. In a second sensing period, voltages at the data lines change to second voltages, the data switch connects the ADC to the data lines, and the ADC converts analog sensing signals corresponding to the second voltages into digital sensing signals output to the controller.
