<P>PROBLEM TO BE SOLVED: To provide a display device, whose lifetime is prolonged by preventing deterioration of image quality by reducing image persistence. <P>SOLUTION: A display device 10 includes a static image region detecting unit 3 for detecting static image data from video data 53. In addition, a detection unit 7 for detecting, as an edge portion, a pair of pixels, having a level difference of image data larger than a preset level difference, of a plurality of pair of adjacent pixels for the static image data. Furthermore, a level-adjusting unit 13 for adjusting the 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 drive unit 5. The level-adjusting unit 13 is for adding/subtracting a random noise to/from the image data of the group of pixels. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
