Abstract: 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.

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.

Abstract: A three-dimensional image display device and a method for displaying a three-dimensional image, and particularly relates to a three-dimensional image display device improving movement degradation and a method for displaying a three-dimensional image. A three-dimensional image display device includes: a display panel; a movement determining unit determining whether an object of a 3D image moved in a direction perpendicular to a surface of the display panel based on image information; a hole-filling unit filling a hole generated according to the movement of the object with an edge region of the object to compensate a movement degradation when it is determined that the object moved in the direction perpendicular to the surface of the display panel; and a 3D input image signal generator generating a 3D input image signal based on the image information compensated with the movement degradation.

Abstract: Display device includes timing controller, display panel, data driver, and scan driver. The timing controller includes an authentication processing unit configured to generate an authentication result based on an authentication control signal. The timing controller converts an input image data signal to data driver control signal and scan driver control signal when the authentication result represents success. The timing controller deactivates the data driver control signal and the scan driver control signal when the authentication result represents fail. The display panel includes plurality of pixels. The data driver generates plurality of data signals based on the data driver control signal and provides the data signals to the pixels through plurality of data signal lines. The scan driver generates plurality of scan signals based on the scan driver control signal and provides the scan signals to the pixels through plurality of scan signals lines.

Abstract: 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.

Abstract: A display apparatus includes a timing controller, a data driver and a display panel. The timing controller receives input image data at a first frequency substantially equal to a frame rate of an input image. The timing controller generates a data signal having the first frequency based on the input image data having the first frequency. The data driver converts the data signal into a data voltage. The display panel displays an image based on the data voltage.
