摘要： A display device includes a display panel including a plurality of pixels, and a panel driver including N registers, where N is an integer greater than 1. The panel driver is configured to divide the display panel into N first detection regions, to perform a first still image detection operation on each of the N first detection regions by using the N registers, to divide the display panel into N second detection regions different from the N first detection regions by using a result of the first still image detection operation, and to perform a second still image detection operation on each of the N second detection regions by using the N registers.

摘要： A display device includes: a display unit including scan lines, data lines, unit areas corresponding to intersections of the scan lines and the data lines, the unit areas including first unit areas in an effective display area, second unit areas in a dummy area around the effective display area, some of the second unit areas being smaller than the first unit areas, and pixels in the first unit areas; a timing controller configured to receive first data including image data corresponding to the first and second unit areas and to convert the first data into second data corresponding to the effective display area; and a data driver configured to generate a data signal corresponding to the second data. The display unit includes a first horizontal line having fewer pixels than the number of the data lines.
