Abstract: A display device includes a display panel and a display image shift controller. The display panel includes a display area in which a display image is displayed and a shift area located within the display area. The display image shift controller generates a route shift signal, where a reference point of the display image is shifted in the shift area based on the route shift signal. The route shift signal includes first and second routes corresponding to a path through which the reference point of the display image is shifted. The first route includes a first sub-route and a second sub-route. The second route includes a third sub-route and a fourth sub-route. The first, second, third, and fourth sub-routes are different from each other.

Abstract: A display device includes a display panel including pixels, and a driver to drive the display panel based on input image data. The driver performs a sensing operation for the pixels, to selectively perform the sensing operation by comparing grayscale values of the input image data and a reference grayscale value, to selectively perform a luminance control operation for controlling luminance of the display panel in response to a luminance control signal, and to adjust the reference grayscale value when the luminance control operation is performed.

Abstract: A display apparatus includes a display panel and a display panel driver. The display panel driver drives the display panel. The display panel driver determines at least one selected from a first low luminance pattern and a second low luminance pattern, where the first lower luminance pattern includes a first low luminance area at a first end portion of the display panel in a vertical direction and a second low luminance area at a second end portion of the display panel in the vertical direction, and the second low luminance pattern includes a third low luminance area at a first end portion of the display panel in a horizontal direction and a fourth low luminance area at a second end portion of the display panel in the horizontal direction. The display panel driver determines a compensation area including a boundary between a low luminance area and a normal area.

Abstract: A display device is disclosed that includes a display panel, a controller, and a data driver. The controller is configured to determine first luminances with respect to a reference grayscale in a second frame when the reference grayscale is displayed in the second frame after the reference grayscale is displayed in a first frame. The controller is configured to determine second luminances with respect to the reference grayscale in the second frame when the reference grayscale is displayed in the second frame after a minimum grayscale is displayed in the first frame. The controller is further configured to temporally and spatially arrange first data corresponding to the reference grayscale and second data corresponding to the minimum grayscale to generate a data signal. And, the controller is configured to drive the display panel with a digital driving method in a first grayscale section, and drive the display panel with an analog driving method in a second grayscale section. The data driver is configured to generate a data voltage based on the data signal.

Abstract: A display apparatus includes a display panel, a data driver, a driving controller and a power voltage generator. The display panel displays an image. The data driver outputs a data voltage to the display panel. The driving controller controls an operation of the data driver. The power voltage generator outputs a power voltage of the display panel. The data driver outputs a clock recovery signal representing whether a clock recovery operation is normal or abnormal to the driving controller. The driving controller generates an overcurrent signal representing an overcurrent based on the clock recovery signal and outputs the overcurrent signal to the power voltage generator.
