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.

20. A display device, comprising:
-
a spatial light modulator; and a lighting source; wherein the lighting source is configured to contribute to the production of a low resolution version of a desired image to be imaged onto the spatial light modulator; wherein the low resolution version of the desired image comprises a series of low resolution lighting elements that mix together to form a smoothly varying pattern of light on the spatial light modulator including a spread function of 0.3d2 to 3d2 where d2 is a spacing between the lighting elements - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
