摘要： An apparatus and a method that drives an LCD device is provided. The apparatus that drives an LCD device includes an image display unit that includes liquid crystal cells that are formed in areas defined by a plurality of gate lines and a plurality of data lines. A data driver provides analog video signals to the data lines. A gate driver provides scan pulses to the gate lines. A data converter determines still images and moving images between adjacent frames of input data and generates modulated data that generates only undershoot at a boundary part of the still images and the moving images. A timing controller arranges the modulated data and provides it to the data driver.

摘要： An organic light emitting diode display device for changing a gamma reference voltage step by step in accordance with an image brightness of a current frame to reduce damage with which the organic light emitting diode and the driving transistor thereof are applied is disclosed. In the organic light emitting diode display device, a brightness detector calculates a maximum brightness value of each pixel using inputted image data of current frame. An adder adds all maximum brightness values of each pixel which are detected by the brightness detector. An average value calculator calculates an average brightness value of a current frame using an added value of maximum brightness values which are added by the adder. A gamma weight calculator calculates a gamma reference voltage weight which is set to correspond to the calculated average brightness value among predetermined gamma reference voltage weights. And a gamma reference voltage generator changes a gamma reference voltage step by step in accordance with a gamma reference voltage weight which is calculated by the gamma weight calculator.
