Abstract: A display device including a display panel which includes pixels connected to gate lines and data lines; and an image display control unit controlling an input image signal to be converted into a data signal and, thereby, display an image on the display panel. The image display control unit outputs the data signal so that a position of an image being displayed on the display panel is changed when the image signal is the same for a preselected time period and sets a next position change time period of the image according to a distance between an original position of the image and a changed position of the image.

Abstract: A method of driving a display panel includes dividing an input image into a plurality of segments, generating a flicker value of a segment of the plurality of segments, determining whether to compensate the flicker value of the segment or not according to a segment size, compensating the flicker value of the segment based on the segment size, determining a frame rate of the display panel based on the flicker value of the segment and outputting a data voltage to the display panel in the frame rate. The flicker value of the segment is compensated based on the flicker value of the segment and flicker values of segments that are adjacent to the segment.

Abstract: A display device includes a display panel including a first partial panel region and a second partial panel region, and a panel driver configured to drive the display panel. The panel driver determines a first driving frequency for the first partial panel region and a second driving frequency for the second partial panel region. When the first driving frequency and the second driving frequency are different from each other, the panel driver sets a boundary portion including a boundary between the first partial panel region and the second partial panel region, and determines a third driving frequency for the boundary portion to be between the first driving frequency and the second driving frequency.

Abstract: A display apparatus includes a display panel, a gate driver, a data driver, and a driving controller. The display panel displays an image based on input image data. The gate driver outputs a gate signal to the display panel. The data driver outputs a data voltage to the display panel. The driving controller selectively determines a driving mode of the display apparatus between one of a normal driving mode and a low frequency driving mode, and determines a driving frequency of the display panel based on the input image data. The driving controller includes a flicker value storage storing flicker values for grayscale values of the input image data and a data remapper converting the grayscale value of the input image data to decrease a size of a maximum frequency grayscale area corresponding to a maximum driving frequency in the low frequency driving mode.
