Abstract
A display device having a prolonged lifetime by preventing deterioration of image quality by reducing a burn-in is provided. A display device includes a still image region detecting unit for detecting still image data from video data, a detecting unit for detecting, as an edge portion, a pair of pixels having a level difference of image data larger than a set level difference, of a plurality of pair of adjacent pixels for the still image data, and a level adjusting unit for adjusting a level of the image data of a group of pixels including the edge portion and arranged consecutively and outputting the image data after the adjustment to a driving unit. The level adjusting unit adds/subtracts a random noise to/from the image data of the group of pixels.
Claims27
A display device for displaying images based on video data inputted from the outside, comprising:
- a display unit having a plurality of pixels, each being composed of a plurality of sub pixels having different colors or a single monochrome sub pixel;
- a driving unit for driving the display unit based on the video data;
- a still image region detecting unit for detecting a still image region from the video data;
- and
- a burn-in reduction processing unit for performing a burn-in reduction process for sub pixels located in the still image region.
