    Publication number: 20110216172
    Abstract: A method for reducing cross talk for a video displayed on a liquid crystal display includes addressing a portion of the liquid crystal display with data for first and second frames for a left view and a right view of a stereoscopic pair of images while a backlight of the liquid crystal display is free from illuminating the liquid crystal display. Illuminating the addressed portion of the display for the left view and the right view with the backlight after the addressing of the liquid crystal display. Wherein the addressing and the illumination occurs within respective frames of the video.
