Abstract:
1. A method for displaying an image on a liquid crystal display, said method comprising: (a) illuminating a first display pixel at a first non-zero illumination level during an initial frame; (b) illuminating said first display pixel at a second non-zero illumination level during a subsequent frame, wherein said subsequent frame is temporally later than said initial frame; (c) wherein said first display pixel is selectively decreased in illumination to another illumination level, based upon an estimation of movement in said image between said initial frame and said subsequent frame, where said estimation is made by comparing at least one image pixel within a first region of a selected one of said initial frame and said subsequent frame of said image to at least one image pixel within a second region of said selected one of said initial frame and said subsequent frame, after illuminating said first display pixel during said initial frame and before illuminating said first display pixel during said subsequent frame, where said display is free from including a temporal frame buffer having a capacity greater than 50% of the size of the displayed said image, and where said estimation of movement in said image between said initial frame and said subsequent frame, upon which said another illumination level is based, is made without comparing said at least one image pixel within either of said first region and said second region of said selected one of said initial frame and said subsequent frame to any pixel of the one of said initial frame and said subsequent frame not selected.
