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 method of driving a display panel includes determining whether an input data signal represents a video image or a static image, determining whether the input data signal has a color difference generating pattern and outputting an output data signal. The output data signal has a first frequency if the input data signal represents a video image. The output data signal has the first frequency if the input data signal represents a static image and the input data signal includes the color difference generating pattern. The output data signal has a second frequency lower than the first frequency if the input data signal represents a static image and the input data signal does not include the color difference generating pattern.

Abstract: A method of compensating an image to be display on a display panel is disclosed. In one aspect, the method includes receiving a first input image and adjusting a contrast sensitivity of the first input image. The method also includes calculating a first derivative of luminance of a pixel included in the adjusted image, calculating a second derivative of the luminance of the pixel, and accumulating the first and second derivatives. The method further includes determining a burn-in causing boundary based at least in part on the accumulated first and second derivatives, receiving a second input image, and comparing the burn-in causing boundary to a boundary of the second input image to determine whether to apply burn-in compensation. The method finally includes compensating a portion of the second input image corresponding to the burn-in causing boundary based at least in part on an unsharpening filter.
