Claim One:
1. A display apparatus comprising: a display panel comprising a data line, a gate line and a sub-pixel connected between the data line and the gate line; a gamma data generator comprising a spatial pattern having a high gamma and a low gamma corresponding to a plurality of sub-pixels arranged in a matrix array for a space division configuration, a temporal pattern having the high gamma and the low gamma corresponding to the plurality of sub-pixels for a time division configuration, a spatio-temporal pattern having the high gamma and the low gamma corresponding to the plurality of sub-pixels for a space and time division configuration, and to generate gamma data of a sub-pixel using at least two of the spatial pattern, the temporal pattern or the spatio-temporal pattern in a cascade configuration, a first gamma controller configured to generate first gamma data of the sub-pixel being high gamma data or low gamma data corresponding to image data of the sub-pixel based on a first preset pattern, which is preset to a first one among the spatial, temporal or spatio-temporal patterns, and a second gamma controller configured to generate second gamma data of the sub-pixel being high gamma data or low gamma data corresponding to the first gamma data of the sub-pixel based on a second preset pattern, which is preset to a second one among the spatial, temporal or spatio-temporal patterns; and a data driver configured to convert the first gamma data and the second gamma data to a data voltage and to output the data voltage to the data line.
