Abstract: A display apparatus and a method of driving the same in which a selector outputs one of two high gamma values and one of two low gamma values in one frame unit in response to a selection signal. A gamma reference voltage generator outputs a high gamma reference voltage corresponding to the selected high gamma value and a low gamma reference voltage corresponding to the selected low gamma value. A data driving circuit outputs a first data voltage based on the high gamma reference voltage during a first active period and outputs a second data voltage based on the low gamma reference voltage during a second active period. Thus, a display panel may display an image using data voltages corresponding to different gamma curves in one frame unit, thereby improving visibility of the display apparatus.
