Abstract: A display system includes a measurer, a measured data filter and a compensation data generator. The measurer measures an image at a measuring point of a display panel to generate measured data. The measured data filter removes a false measured data outside an allowable range among the measured data. The compensation data generator generates representative compensation data compensating the image based on the measured data in which the false measured data is removed.

Abstract: A display device includes an image analyzing part which determines whether current frame image data includes a crosstalk pattern, and a gamma voltage generator which generates current frame gamma data by applying the asymmetric gamma when the current frame image data do not include the crosstalk pattern, and generates the current frame gamma data by applying a symmetric gamma when the current frame image data includes the crosstalk pattern. The positive polarity and negative polarity data voltages of the asymmetric gamma are asymmetric with each other for each of the grayscales, and the positive polarity and negative polarity data voltages of the symmetric gamma are symmetric with each other for each of the grayscales.

Abstract: A display device includes a display panel including a plurality of data lines and a plurality of color pixels arranged into rows, a black-grayscale correcting circuit, and a data driving circuit. The black-grayscale circuit corrects a black-level of black-grayscale data of input grayscale data to generate corrected image data. The black-grayscale circuit corrects the black-grayscale data to be applied to a current one of the rows during a current horizontal period based on the input grayscale data to be applied to a previous one of the rows during a previous horizontal period and the input grayscale data to be applied to a next one of the rows during a next horizontal period. The data driving circuit converts the corrected image data into data voltages for output to the data lines.
