Abstract: A display device, includes: a scan driver configured to sequentially supply scan signals having a turn-on level to the first scan line and the second scan line during a first period and to concurrently supply scan signals having a turn-on level to the first scan line and the second scan line during a second period after the first period, wherein: a mask period corresponds to a difference between a start point of the second period and a start point of the first period in a next frame period, a first frame period and a second frame period have different mask periods, a third frame period between the first frame period and the second frame period has a same mask period as the first frame period, and a fourth frame period between the first frame period and the second frame period has a same mask period as the second frame period.

Abstract: A display device includes a processor which supplies grayscale data in active periods of frame periods and stops supply of the grayscale data in blank periods of the frame periods, a timing controller which generates a change signal when a difference between a first blank period of a first frame period and a second blank period of a second frame period is greater than a threshold value, a power supply which supplies a first power voltage having a voltage level changed based on the change signal to a first power line, and pixels commonly connected to the first power line.

Abstract: A display device includes a plurality of pixels, a power supply, a voltmeter, and a timing controller. The power supply is configured to generate an initialization voltage to be supplied to a sensing pixel among the pixels. The voltmeter is configured to measure a first value of the initialization voltage supplied to the sensing pixel during an active period of a frame period and a second value of the initialization voltage supplied to the sensing pixel during a vertical blank period of the frame period. The timing controller is configured to generate rewrite image data that is supplied to the sensing pixel during the vertical blank period. The rewrite image data is generated from image data applied to the pixels during the active period and a difference between the first and second values.
