Abstract:
1. A liquid crystal display device, comprising: a liquid crystal panel having a plurality of gate lines and data lines crossing each other, and having red (R), green (G) and blue (B) pixels arranged in a matrix pattern; a light source transmitting light through the R, G, and B pixels creating red, green, and blue colors respectively; a gate driving unit for applying scan signals to the gate lines; a lookup table for storing gray scale values of image information including R, G and B data, where a gray scale value of a gray level of the B data that is lower than a gray level at which a color saturation is reduced, is stored as a gray scale value of gray levels that are higher than the gray level at which the color saturation is reduced, a data processing unit for compensating image information according to the gray scale values in the lookup table; and a data driving unit for receiving the compensated image information and applying the compensated image information to the data lines.
