Abstract (en)
[origin: WO9725706A1] A method for addressing a flat screen consisting of rows and columns with pixels at the intersections thereof, wherein, at the start of each sampling of the video signal to be displayed on the screen, a voltage (Vr) higher than the useful voltage range (V) is applied to the selected pixel for a time tr, whereafter the useful voltage is sampled for a time ts. The invention is useful for LCD drivers.
