| 主权项 | 1. A directional pixel for use in a display screen, the directional pixel to receive a planar lightbeam and comprising: a light propagating layer to propagate the planar lightbeam; and a grating in the light propagating layer to scatter a portion of the planar lightbeam out of the light propagating layer as a directional lightbeam having a direction and an angular spread controlled by the grating, wherein the grating in the light propagating layer is one or both of in a surface of the light propagating layer and in a material on the propagating layer surface. | ||
