    Abstract: A display device includes: a memory; a pixel unit including first pixels disposed with a first density in a first area and second pixels disposed with a second density smaller than the first density in a second area in contact with the first area; and a degradation compensator which updates degradation information stored in the memory, based on input grayscales for the first and second pixels, and changes the input grayscales to output grayscales, based on the degradation information. The degradation compensator stores the degradation information in the memory in a unit of block for the pixel unit. The memory stores only first degradation information for each of first blocks including only the first pixels, stores only second degradation information for each of second blocks including only the second pixels, and stores the first and second degradation information for each of third blocks including both the first and second pixels.

    Abstract: A controller for a liquid crystal display includes a data driver and a gate driver. The data driver applies data voltages having different polarities to a first pixel and a second pixel. The gate driver applies different gate-on voltages to a first gate line coupled to the first pixel and a second gate line coupled to the second pixel. The gate-on voltages have at least one of a different width or a different level when at least one of a still image or a moving picture is to be displayed. The different gate-on voltages translate into different pixel charging speeds, which may translate into improvements in the luminance and/or other properties of the display.
