Abstract

A method is arranged to process a frame for an LCD with a modified polarity pattern. The pattern employs a polarity reversal scheme that results in line inversion and/or dot inversion patterns that are observable by pixel locations within the frame. The drive polarity for the column drivers in the LCD is toggled according to the modified polarity pattern. The scanning sequence for each row on the display is modified for cooperation with the pattern. A first subframe is scanned during a first interval while applying a first set of drive polarities. A second subframe is scanned during a second interval that is non-overlapping with the first time interval. The application of the method enables the column drivers in the LCD to operate with reduced power while retaining the benefits of line and dot inversion techniques.
