Abstract: A directional backlight is disclosed. The directional backlight has a plurality of light sources to generate a plurality of input planar lightbeams. The plurality of input planar lightbeams illuminates a directional backplane that has a plurality of directional pixels to scatter the plurality of input planar lightbeams into a plurality of directional lightbeams. Each directional lightbeam has a direction and angular spread control led by characteristics of a directional pixel in the plurality of directional pixels. The directional backlight can be used to generate a 3D image by speci fying the characteristics of the directional pixels in the directional backplane.

Abstract: A directional pixel for use in a display screen is disclosed. The directional pixel receives a planar Iightbeam and includes a light propagating layer and a grating to scatter a portion of the planar Iightbeam into a directional Iightbeam having a direction and angular spread controlled by the grating.
