    Abstract: A display device includes: a pixel connected to each of a first scan line, a second scan line, and a data line; a scan driver supplying a first scan signal to the first scan line and a second scan signal to the second scan line; a controller dividing one frame period into an active period and a blank period and generating a count signal in which a time duration of the blank period is counted and a power control signal; a data driver supplying a data signal to the data line; and a power supply controlling a source driving voltage supplied to the data driver according to a duration of the blank period based on the power control signal. When the count signal reaches a reference value, the controller supplies a start signal for output of the first scan signal to the scan driver.

    IPC: G09G3/20

    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.
