Color sequential liquid crystal display and a driving method

The present invention discloses a method for color sequential driving type liquid crystal display, comprising the steps of: calculating a four-pixel gray level value of each picture, the pixel includes a white grayscale value, the first color pixel grayscale value, a second color pixel gray step value, the third color pixel gray level value; a first color when the first n pictures of the field, to provide a white backlight unit pixel, the pixel gray scale values ​​of the white sub-pixel n pictures of the first input to the first color subpixel input of the first n pieces of pixel gray level value of the picture color, the second color pixel grayscale value to a second color sub-pixel of the n pieces of input picture; in the second field of the n pictures of the color of the a third color of pixels of the backlight unit, the first input of the third n pictures of the color pixel values ​​to the sub-pixel gray scale, a gray scale value input to the first color sub-pixel and the second sub-pixel color remain open. The present invention also discloses a driving method as described above using a color sequential driving type liquid crystal display.
