  • Displays with a backlight incorporating reflecting layer
    Patent number: 9341887
    Abstract: Displays comprise light control layers (16) in an optical path between a light source (12), such as an array of light emitting diodes and a spatial light modulator (14) such as a liquid crystal display panel. The light control layer comprises an enhanced specular reflector (ESR, 16a) film in optical contact to at least one layer of a transparent or translucent material (16B, 16C). The light control layer transmits light from the light source more readily than the ESR film standing on its own. In some embodiments the display may provide enhanced contrast and peak luminance.
