A display apparatus includes a display panel and a timing controller. The timing controller generates first output image data based on input image data and sets a driving frequency of the display panel as a first frequency in a first operation mode. The timing controller converts the input image data into second output image data and sets the driving frequency of the display panel as a second frequency lower than the first frequency in a second operation mode. The display panel displays a first image based on the first frequency and the first output image data in the first operation mode. The first image is represented by X grayscales. The display panel displays a second image based on the second frequency and the second output image data in the second operation mode. The second image is represented by Y grayscales, where Y is less than X.

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.

A display panel driving apparatus includes a data driving part, a comparing part, a data signal controlling part, and a gate driving part. The data driving part generates a dummy data signal in response to dummy image data, outputs the dummy data signal to a dummy data line of a display panel, generates a data signal in response to image data, and outputs the data signal to a data line of the display panel. The comparing part outputs a comparison signal in response to the dummy data signal and a delayed dummy data signal generated due to a load of the dummy data line. The comparison signal indicates how much the delayed dummy data signal is delayed with respect to the dummy data signal. The data signal controlling part controls the data signal using the comparison signal.
