Abstract
An active matrix liquid crystal display device, and a method for the driving thereof, comprising driving the pixels (12) with a pre-determined drive voltage level, and driving the pixels with overdrive correction levels of drive voltage; wherein the pre-determined drive voltage level is the same for each pixel (12), and the overdrive correction level of drive voltage for each pixel (12) is the overdrive corrected voltage level for each respective pixel (12) corresponding to the data signal for the respective pixel (12). A backlight (28) may be switched on or off in relation to whether the pixels (12) or certain pixels are being driven with the pre-determined drive voltage level or with an overdrive correction level of drive voltage.
