  • EDGE LIT LOCALLY DIMMED DISPLAY
    Publication number: 20110216387
    Abstract: An edge lit locally dimmed display has a spatial light modulator illuminated by a light source. The light source is positioned at an edge and behind the spatial light modulator. The spatial light modulator is illuminated with a low resolution version of a desired image. The illumination may comprise a series of lighting elements that vary smoothly from one element to another at the spatial light modulator.
