LIQUID CRYSTAL DISPLAY AND METHOD FOR DRIVING THEREOF

摘要

A liquid crystal display and a driving method thereof are provided to detect a kickback voltage by detecting the pixel voltage applied to liquid crystals included in a pixel region, and to prevent an after image and flicker by supplying the optimal common voltage in consideration of the kickback voltage to a liquid crystal display panel. A liquid crystal display includes a data driving unit(400) for generating a data voltage(Vd) corresponding to a data signal input from the outside; a liquid crystal display panel(100) having a plurality of pixel regions(PA) and displaying an image corresponding to a pixel voltage(Vp) of the pixel region corresponding to the data voltage; and a driving voltage generating unit(700) for supplying a common voltage(Vcom) corresponding to the pixel voltage to the liquid crystal display panel.
