1. A video processing method of a liquid crystal display device comprising:

  • a) determining whether a current frame is a motion picture by comparing data of a current frame with data of a previous frame;

    b) converting and outputting a number of bits of a white gradation data of the current frame and outputting data of the other gradations without the bit-conversion, when it is determined in the first step that the current frame is the motion picture;

    c) outputting the data of the current frame without the bit-conversion when it is determined in the first step that the current frame is a still image; and

    d) comparing the output data from the second or third step with data of a previous frame and performing a conversion process to generate overdriving control (ODC) data when the compared data are not identical.
