Abstract: A liquid crystal display includes a backlight that provides light and selectively modifies the transmission of light from the backlight to the front of the display. The backlight includes a plurality of spaced apart light waveguides and a plurality of selection elements associated with the light waveguides that change the characteristics of the material of the light waveguides to selectively direct the transmission of light toward the liquid crystal layer. The combination of the waveguides and the selection elements provide light to the front of the display in a non-uniform temporal manner and a non-uniform spatial manner during a frame.

Abstract: A system for detecting newton ring mura on a display includes sensing an image of the display with an image capture device and determining a border boundary of an illuminated portion of the display. The image is spatially filtered as defined by the border boundary using a filter that reduces sensor noise and a grid pattern of the display. The spatially filtered image is processed to determine if a region proximate a pixel location is a potential newton ring mura defect and characterizing the potential newton ring mura defects to remove at least one of the potential newton ring mura defects.

Abstract: A backlit display with improved dynamic range. A first pixel is illuminated at a first non-zero illumination level during a first frame and a second non-zero illumination level during a second frame, immediately following the first frame. The second illumination level is greater than the first level. The first pixel is decreased in illumination to a level less than the first illumination level prior to illuminating the first pixel at the second illumination level during the second frame.
