Abstract
Embodiments relate to a display device including an active display area with pixels arranged in rows and columns, where a focus area of the active display area is operated in a progressive scanning manner and a non-focus area of the active display area is operated in an interlaced scanning manner. The active display area is driven by a gate driver circuit that supplies gate signals the pixels. First stages of the gate driver circuit are coupled to first rows of the pixels that are in the focus area and output first gate signals in the progressive scanning manner. Second stages of the gate driver circuit are coupled to second rows of the pixels that are in the non-focus area and output second gate signals in the interlaced scanning manner.
