Abstract
A display device includes a display panel including a plurality of pixel circuits each having a light-emitting element, the display panel being divided into a plurality of display regions comprising respective groups of the pixel circuits, and a display panel driving circuit configured to drive the display panel by sequentially performing an emission preparation operation, a scan operation, and an emission operation for the pixel circuits, and configured to perform the emission operation independently on each of the display regions, wherein, in each frame, the display panel driving circuit is configured to calculate a region grayscale that each of the display regions is to implement by analyzing grayscale data to be applied to the pixel circuits in each of the display regions, and to change a length of an emission period for each of the display regions based on the calculated region grayscale, the emission operation being performed in the emission period.
