Abstract:
1. A driving method for a liquid crystal display, the liquid crystal display includes a first substrate, a second substrate, a plurality of data lines, a plurality of gate lines and a liquid crystal molecule layer between the first substrate and the second substrate, wherein the plurality of data lines and the plurality of gate lines are disposed on the first substrate to define a plurality of pixels and a common electrode disposed on the second substrate, the method comprising the steps: using an over driving voltage to write black data to the pixels, the over driving voltage is larger than a critical voltage which makes the liquid crystal molecules of the liquid crystal molecule layer rotate to a special angle to just completely block the backlight to make a brightness from the backlight to the pixels be exactly equal to zero and makes the pixels display just complete black image, wherein using an over driving voltage to write black data to the pixels in the black image writing period further comprises: selecting at least some of the pixels to write color data based on a color image signal after the black data is written into the pixels; and turning on a backlight based on the color data.
