Abstract: A display apparatus includes a gamma controller configured to determine whether the target pixel unit is driven in both time division method and space division method based on a plurality of comparison values and a reference condition, and an output controller configured to generate normal gamma-data of the target pixel unit using a normal gamma curve if the plurality of comparison values satisfy the reference condition and to generate high gamma-data and low gamma-data of the target pixel unit using a high gamma curve and a low gamma curve in both time division method and space division method if the plurality of comparison values do not satisfy the reference condition.
