Abstract
A device for controlling common mode electrode voltage in a liquid crystal display includes at least a first sensor for measuring flicker resulting from applying a video signal with a predetermined color and drive level to an imager. A detector for determining a difference between a positive field detector voltage and a negative field detector voltage is used to provide a feed-back loop for feeding back the difference to a controller to adjust the common mode electrode voltage.
