摘要： The present disclosure relates to a liquid crystal display drive device and a method of driving the same. An image processor of a liquid crystal display device may generate second pixel data by applying a first gain, determined according to a brightness level of each LED element, to first pixel data of each subpixel, may calculate a second gain by using a differential value obtained by differentiating the brightness level of each LED element for a location of each subpixel, and a weight and a compensation coefficient determined according to the brightness level of each LED element, generate third pixel data by applying the second gain to the second pixel data, and output the third pixel data.
