Abstract: A display device and a driving method for converting a low-resolution image into a high-resolution image and preventing a visible boundary between partitioned display areas are disclosed. One inventive aspect includes a display panel, a dividing control unit and a scaler. The display panel includes panel areas. The dividing control unit divides an input image into sub-images and the scaler scales the sub-images. The inventive aspect further includes an extra image removing unit and a driver. The extra image removing unit removes an scaled extra image from the scaled sub-image so that the driver provides the processed sub-image to the corresponding panel area.

Abstract: A luminance adjustment part includes a luminance determination part and a data compensation part. The luminance determination part may determine a control value for controlling luminance of a backlight assembly using linear image data that has a linear luminance profile and is generated by performing a de-gamma process on a first copy of input image data that has a nonlinear luminance profile. The compensation part may compensate pixel data that corresponds to pixels of a display panel using the control value, the pixel data being generated using a second copy of the input image data. Thus, color distortion of a displayed image as perceived by a viewer may be minimized when power consumption of a display apparatus that includes the display panel is decreased.

Abstract: An image processing part includes an edge enhancing part, an artifact detecting part and a compensating part. The edge enhancing part emphasizes an edge portion of an object in input image data. The artifact detecting part detects a corner outlier artifact at an area adjacent to the edge portion of the object. The compensating part compensates the corner outlier artifact. Accordingly, the edge portion of the object may be enhanced and the corner outlier artifact is decreased so that the display quality may be improved.
