Abstract
A backlight for a display comprises a plurality of independently controllable light sources and inclined surfaces inclining in a radially outward direction from each light source for shaping the distribution of emitted light. The light sources may each comprise a group of differently-colored light emitters. The backlight may include light integrators configured to mix light of the differently-colored light emitters. Inclined surfaces for shaping the distribution of emitted light may be arranged around exits of the light integrators.
