Abstract: A display apparatus includes: a display panel including a data line, a gate line crossing the data line, and a sub pixel connected to the data line and the gate line; a gamma data generator configured to output normal gamma data of a normal gamma curve corresponding to image data when a grayscale of the image data is inside a first grayscale range, and to output high gamma data of a high gamma curve or low gamma data of a low gamma curve based on a spatio-temporal pattern when the grayscale of the image data is outside the first grayscale range; and a data driver configured to convert the gamma data outputted from the gamma data generator to a data voltage and to output the data voltage to the data line.

Abstract: A timing controller for a display apparatus includes a polarity comparison part and a compensation part. The polarity comparison part compares a first polarity of a first data voltage with a second polarity of a second data voltage, the first data voltage corresponding to a first pixel in a first frame and generated based on a first gamma voltage, the second data voltage corresponding to the first pixel in a second frame and generated based on a second gamma voltage. The compensation part compensates the second data voltage based on a first look-up table, if the first polarity is the same as the second polarity, and compensates the second data voltage based on a second look-up table, if the first polarity is different from the second polarity.

Abstract: A display apparatus includes a gamma data generator comprising a spatial pattern having at least a high gamma and a low gamma corresponding to a plurality of sub-pixels arranged in a matrix array in a space division configuration, a temporal pattern having the high gamma and the low gamma corresponding to the plurality of sub-pixels in a time division configuration and a spatio-temporal pattern having the high gamma and the low gamma corresponding to the plurality of sub-pixels in both a space and time division configuration, and configured to generate gamma data of a sub-pixel using the spatial pattern, the temporal pattern and the spatio-temporal pattern in a cascade configuration.
