A display device includes a display panel which includes a letterbox area and an image display area which displays an image and includes a boundary luminance variable area extending from the letterbox area; and a luminance control unit which controls a reduced luminance amount of the boundary luminance variable area based on the image.

Display device

A display device includes a display panel and a display driving circuit having improved degradation uniformity. The display panel includes sub-pixels, each of which includes a light emitting element and a driving transistor. The display driving circuit drives the display panel to display a degradation uniformity restoration image in an afterimage occurrence predicted area detected in the display panel during an image quality control period. The afterimage occurrence predicted area includes first and second sub-pixels of the sub-pixels. Before the image quality control period, the amount of accumulated current having flowed through the first sub-pixel is greater than the amount of accumulated current having flowed through the second sub-pixel. During the image quality control period, the amount of current flowing through the second sub-pixel is greater than the amount of current flowing through the first sub-pixel.
