Patent ID: 8542171

Claim:
A method for driving a liquid crystal display, the liquid crystal display comprising a back light module and a pixel array having a first row of pixels and a second row of pixels, the method comprising: (a) turning on a thin film transistor of a first pixel in the first row of pixels by a first scan signal and outputting a first pixel voltage to the first pixel in the first row of pixels to change a transmittance of the first pixel, and then outputting a second pixel voltage to a second pixel in the second row of pixels to change a transmittance of the second pixel; (b) turning on the backlight module; (c) adjusting a pixel electrode voltage of the first pixel at a first predetermined time point after outputting the first pixel voltage and before turning on the thin film transistor of the first pixel by a second scan signal next to and occurring immediately after the first scan signal; and (d) adjusting a pixel electrode voltage of the second pixel at a second predetermined time point after outputting the second pixel voltage, wherein the second predetermined time point is subsequent to the first predetermined time point, wherein when the first pixel voltage substantially equals the second pixel voltage, an integration of the transmittance of the first pixel over time in a lighting period of the backlight module is a first light intensity value and an integration of the transmittance of the second pixel over the time in the lighting period of the backlight module is a second light intensity value, and the difference between the first light intensity value and the second light intensity value is substantially smaller than 20% of the first light intensity value.
