Abstract: A dynamic image split method for a dual cell LCD that includes a back cell and a front cell is proposed to obtain a smoother back-cell image. Multiple desired effective transmittances that correspond to a group of front-cell pixels are taken into consideration in determining a transmittance for a back-cell pixel. The front-cell pixels in the group are related in position to the back-cell, and cooperatively form an area that is larger than and overlaps an area of the back-cell pixel.
