Abstract: Disclosed are a liquid crystal display and a method of driving the same. The liquid crystal display includes a liquid crystal display panel displaying an image; a gate driver applying gate signals to the liquid crystal display panel; a data driver applying data signals to the liquid crystal display panel; and a signal controller controlling the gate driver and the data driver. The signal controller includes a control signal generating unit multiplying a frame rate, and an image signal processing unit correcting image data of each of multiplied frames by alternately using a plurality of correction data set having different correction characteristics.

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.
