Abstract: A display device comprises pixels arranged in a display area of a display panel, and a display driver determining whether image data indicates still image characteristics or moving image characteristics and controlling a supply timing of data voltages and pixel driving control signals supplied to the pixels based on the determination result, wherein the display driver selectively adjusts a driving frequency for driving the pixels and a level of a high-potential voltage supplied to the pixels based on as result of grayscale analysis of the image data.

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 net power control circuit configured to analyze a screen load from an input image signal to generate a load signal including a load value corresponding to the screen load; and an overcurrent protection circuit configured to set a set current value at a predetermined ratio with respect to a global current value corresponding to the load value included in the load signal, and to determine whether or not the display device is powered off based on the set current value.
