    Abstract: A display device includes display panels, a data converter that renders input image data to convert the input image data corresponding to edge regions of the display panels adjacent to a boundary portion between the display panels into correction data, and a driving controller that receives the correction data and generates a control signal that drives the display panels based on the correction data. The data converter generates the correction data in which an image displayed in the edge region is shifted based on a difference between values of the input image data corresponding to the edge regions of the display panels adjacent to the boundary portion between the display panels adjacent to each other.

    Abstract: A display apparatus includes a liquid crystal panel including gate lines, data lines, and pixels, a gate driver, a data driver, and a timing controller. The pixels include first and second pixels. The first and second pixels are arranged in pixel rows adjacent to each other, arranged in different pixel columns, connected to the same gate line, display the same color, and receive data voltages having different polarities from each other. The image data include first pixel data displayed in the first pixels and second pixel data displayed in the second pixels. When the first pixel data have a first grayscale value and the second pixel data have a second grayscale value different from the first grayscale value, the timing controller modulates the first and second pixel data to allow the first and second pixel data to have a grayscale value between the first and second grayscale values.
