Abstract: Multibeam diffraction grating-based color backlighting includes a plate light guide, a multibeam diffraction grating at a surface of the plate light guide, and light sources laterally displaced from one another in a direction corresponding to a propagation axis of the plate light guide. The light sources produce light of different colors. The plate light guide is to guide light from the light sources. The multibeam diffraction grating is to couple out a portion of the guided light using diffractive coupling as a plurality of light beams of different colors in a plurality of different principal angular directions.

Abstract translation: 基于多光束衍射光栅的彩色背光包括平板光导，平板光导的表面处的多波束衍射光栅以及在对应于平板光导的传播轴的方向上彼此横向移位的光源。 光源产生不同颜色的光。 平板导光板用于引导来自光源的光。 多光束衍射光栅是使用衍射耦合作为在多个不同主角方向上的不同颜色的多个光束来耦合输出的一部分导光。

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