Abstract:
A backlight (42, 62) for a display (40, 60) comprises a plurality of independently controllable light sources (48) and inclined surfaces inclining in a radially outward direction from each light source for shaping the distribution of emitted light. The light sources (48) may each comprise a group of differently-colored light emitters. The backlight 842, 62) may include light integrators (64) configured to mix light of the differently-colored light emitters. Inclined surfaces (44) for shaping the distribution of emitted light may be arranged around exits of the light integrators (64).
