Abstract: An organic light emitting display device includes a display panel including and a plurality of pixels, a gate driver configured to a normal gate signal and an alternative gate signal to the pixels, a data driver configured to provide a data signal to the pixels, an emission control driver configured to an emission control signal to the pixels, and a controller configured to control the gate driver, the data driver, and the emission control driver. Each of the pixels is driven by the normal gate signal in a first driving mode and is driven by the alternative gate signal in a second driving mode. A threshold voltage of a first transistor is compensated in the first driving mode and the threshold voltage of the first transistor is not compensated in the second driving mode.

Abstract: A method of driving a display panel is proposed. The method includes determining whether an input image data represents a video image or a static image, determining whether an image transition occurs in the input image data when the input image data represents the static image, and inserting a plurality of image sticking compensation frames between normal frames in a low frequency driving when the image transition occurs in the input image data between the normal frames. The number of the image sticking compensation frame may be properly adjusted during a cycle of low frequency driving.

Abstract: A display apparatus having an edge determiner configured to determine an edge area of the moving object based on moving direction and moving speed corresponding to the moving vector. The display apparatus also includes a gamma output controller configured to output normal high data of a high gamma curve and normal low data of a low gamma curve as gamma data of input data corresponding to a remaining area except for the edge area, and to output enhanced high data of the high gamma curve and enhanced low data of the low gamma curve as gamma data of input data corresponding to the edge area, in both time division method and space division method based on a spatiotemporal sequential pattern.

Abstract: A liquid crystal display includes a signal controller to generate a plurality of start pulse signals based on a plurality of eye blinking signals during a predetermined mode of operation. The start pulse signals are generated in a manner different from a vertical synchronization signal. The start signals may be generated to have an irregular spacing which corresponds to the blinking signals, which may be different from a constant spacing used during display of moving images. The predetermined mode may be a still image mode.

Abstract: A method of driving a display panel is provided. The method includes generating first compensated and second compensated data based on input image data, outputting the first compensated data to a data driver during a first frame, outputting the first smoothing data to the data driver during a second frame subsequent to the first frame, and outputting the second compensated data to the data driver during an n-th frame subsequent to the second frame (where n is a natural number greater than two). The first smoothing data has a value between a value of the first compensated data and a value of the second compensated data.

Abstract: An image processor, a display device including the same, and a method for driving display panel using the same are disclosed. In one aspect, the display device includes an image shifter configured to shift a data signal by at least one pixel based at least in part on a shift start signal and output the shifted data signal and a shift direction signal. The display device also includes an image buffer configured to output current data and previous data based at least in part on the shifted data signal and the shift direction signal. The display device also includes an image mixer configured to mix the current data and the previous data over M frames starting at a start frame when the shift start signal is received and output image data, M being a natural number.
