Dual‐cell LCDs realize pixel‐level dimming by adding a layer of backlight control cell between the and display panel, which generally have ghost effect halo at junction bright content dark affected visual need to be solved. The is part with low brightness around content, there no such in original image, so it looks like shadow effect. more obvious when alignment pixel position dual cells inaccurate. phenomenon that adjacent brightens displayed. We propose dynamic filtering algorithm reduce making smooth transition from content. Experiments on 10.25 inch dual‐cell LCD show has good .
