    Abstract: A head-tracking multiview display and a system provide a plurality of views of a scene as a multiview image. The plurality of views includes a set of primary views of the scene and a secondary view representing a perspective view of the scene that is angularly adjacent to the primary view set. The display and system are multibeam diffraction grating-based and configured to selectively provide the primary view set and an augmented set of views that includes the secondary view and a subset of the views of the primary view set based on a tracked position of a user or a user's head. At a first position the display is configured to provide the primary view set and at a second position the display is configured to provide the augmented view set.

    Abstract: A directional backlight is disclosed. The directional backlight has a directional backplane that has a plurality of directional pixels to scatter a plurality of input planar lightbeams into a plurality of directional lightbeams. Each directional lightbeam has a direction and angular spread controlled by characteristics of a directional pixel in the plurality of directional pixels. A modulation layer having a plurality of modulators modulates the plurality of directional lightbeams. The directional backlight can be used to generate a 3D image with multiple views by specifying the characteristics of the directional pixels in the directional backplane.

    Abstract translation: 公开了一种定向背光源。 定向背光具有定向背板，其具有多个定向像素以将多个输入平面光束散射到多个定向光束中。 每个定向光束具有由多个定向像素中的定向像素的特性控制的方向和角展度。 具有多个调制器的调制层调制多个定向光束。 通过指定定向背板中的方向性像素的特性，定向背光源可用于生成具有多个视图的3D图像。
