Abstract
A field sequential driving method includes the following steps. First, a liquid crystal display (LCD) including a display unit and a backlight unit is provided. The display unit includes several pixel units. Next, a white light source of the backlight unit is enabled during a first sub-frame period of a frame period of the LCD. Then, red and blue sub-pixel data are provided to drive a first sub-pixel and a second sub-pixel in the pixel unit during the first sub-frame period. Next, a green light source of the backlight unit is enabled during a second sub-frame period of the frame period. Thereafter, green sub-pixel data is provided to drive a third sub-pixel of the pixel unit during the second sub-frame period.
