Abstract:
1. A display apparatus comprising: a display panel comprising first to Mth data lines extending in a first direction, where M is an integer greater than 2, first to Nth scan lines extending in a second direction, where N is an integer greater than 2, and a plurality of pixel regions defined by one or more of the data lines and one or more of the scan lines; an image data processor configured to process input image signals and output corrected input image signals; and a data driver configured to receive the corrected input image signals and supply the corrected input image signals to the data lines, wherein the plurality of pixel regions include first to Mth pixel arrays extending in parallel, and the image data signal processor is configured to output the corrected input image signals to adjust a gray value applied to the first pixel array, wherein each of the pixel arrays comprises a plurality of pixels formed in a single column, wherein the image data processor includes an edge representative value calculator configured to analyze the input image signals and output a vertical edge control signal, and a vertical edge corrector configured to output the corrected input image signals to adjust a gray value applied to the first pixel array in response to the vertical edge control signal, and wherein the display panel includes a black matrix surrounding the pixel regions, wherein the first pixel array is located at the leftmost column of the pixel regions, wherein the Mth pixel array is located at the rightmost column of the pixel regions, and wherein the edge representative value calculator is further configured to output the vertical edge control signal based on the average gray value of only the pixels of the first pixel array.
