Abstract: Disclosed are an image-processing circuit capable of improving the ability to express a high-resolution image and a display device having the same and a method of driving a display device. The image-processing circuit determines whether input image data represents one or more of a forward diagonal line edge, a backward diagonal line edge, and a horizontal line edge, and then determines arrangement of a center unit pixel, and thereafter renders data of the center unit pixel into data of a peripheral unit pixel based on edge information and the arrangement of the center unit pixel.

Abstract: In at least one embodiment, a display device includes a panel including a display area in which a plurality of pixels is arranged. An optical module is superposed on the display area. The display area has a low-resolution area having a polygonal shape and superposed on the optical module and a high-resolution area neighboring the low-resolution area, unit pixels having the same size as those of the high-resolution area are arranged in a lower pixel density than that of the high-resolution area and transmission areas are disposed adjacent to the unit pixels in the low-resolution area, and unit pixels and transmission areas are arranged in different forms in a boundary area of the high-resolution area neighboring the low-resolution area according to slopes of the boundary area.
