Display apparatus having increased side-visibility in a high grayscale range and a method of driving the same

A display apparatus, comprising:

• a display panel comprising 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 and 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,
• wherein the first grayscale range comprises a middle grayscale range including middle grayscales which are between low grayscales and high grayscales,
• wherein the gamma data generator is configured to output high gamma data of a high gamma curve and low gamma data of a low gamma curve when the grayscale of the image data is inside a high grayscale range, and
• to output the high gamma data of the high gamma curve and the low gamma data of the low gamma curve when the grayscale of the image data is inside a low grayscale range.
