Abstract: A display device includes: a plurality of pixel blocks each including a plurality of pixels; a scan driver supplying a scan signal to the scan lines and to supply a control signal to the control lines; a data driver supplying an image data voltage or a low grayscale data voltage to the data lines; and a power supply supplying a reference voltage to the pixels, wherein the pixels are configured to receive the image data voltage during a first scan period of a frame, and to receive the low grayscale data voltage during a second scan period of the frame, and the reference voltage supplied to a first pixel row of at least one of the pixel blocks in the first scan period is different from the reference voltage supplied to a last pixel row of at least one of the pixel blocks in the first scan period.

Abstract: A display device includes a scan driver which includes a first stage including a first output terminal connected to a first carry line, a second output terminal connected to a first scan line, and a third output terminal connected to a first sensing line, and a second stage including a first input terminal connected to the first carry line, a fourth output terminal connected to a second scan line, and a fifth output terminal connected to a second sensing line. In a sensing period, signals having a turn-on level are respectively output from the first output terminal, the second output terminal, and the third output terminal during a predetermined delay period before signals having a turn-on level are respectively output from the fourth output terminal and the fifth output terminal.
