Patent ID: 7453430

Claim:
A driving method of a liquid crystal display, wherein the liquid crystal display includes a plurality of scan lines, a plurality of data lines crossing the scan lines, and a plurality of pixels formed at areas defined by the scan lines and the data lines and coupled respectively to the scan lines and the data lines, each pixel having a switch, and R, G, and B color lights are sequentially applied to the pixels, the method comprising: for each of R, G, and B fields in which the R, G, and B color lights are respectively applied, applying a first common voltage and a first gray scale waveform corresponding to first gray scale data to a first pixel among the plurality of pixels in the field of a current frame; and displaying a gray scale which has a level half-way between gray scale levels of the first gray scale data and second gray scale data by applying a second common voltage and a second gray scale waveform corresponding to the second gray scale data to the first pixel in the field of a next frame, the gray scale level of the second gray scale data being different from the gray scale level of the first gray scale data by one level.
