Abstract
A multiview 3D wrist watch is disclosed. The wrist watch has clock circuitry to determine a time and a plurality of light sources to generate a plurality of input planar lightbeams. A directional backplane having a plurality of directional pixels scatters the plurality of input planar lightbeams into a plurality of directional lightbeams, each directional lightbeam having a direction and angular spread controlled by characteristics of a directional pixel in the plurality of directional pixels. A shutter layer receives the time from the clock circuitry and modulates the plurality of directional lightbeams to generate a 3D time view.

A multiview 3D wrist watch, comprising:
- clock circuitry to determine a time;
- a plurality of light sources to generate a plurality of input planar lightbeams;
- a directional backplane configured to guide the plurality of input planar lightbeams, the directional backplane having a plurality of directional pixels configured to scatter a fraction of the guided input planar lightbeams out of a surface of the directional backplane into a plurality of directional lightbeams corresponding to directions of different views of a three-dimensional (3D) image, each directional lightbeam having a direction and angular spread controlled by characteristics of a directional pixel in the plurality of directional pixels;
- and
- a shutter layer configured to receive the time from the clock circuitry and modulate the plurality of directional lightbeams to generate a 3D time view as the 3D image.
A method of generating a 3D time view in a multiview 3D wrist watch, the method comprising:
- determining a time to be displayed by the wrist watch;
- guiding a plurality of input planar lightbeams from a plurality of light sources in the wrist watch within a directional backplane comprising a slab of transparent material;
- generating a plurality of directional lightbeams by scattering a fraction of the guided input planar lightbeams out of the transparent material slab using a plurality of directional pixels in the directional backplane, the directional pixels comprising patterned gratings to produce directional lightbeams having a predetermined angle and angular spread corresponding to different predetermined views of a 3D image;
- and
- modulating the plurality of directional lightbeams using a shutter layer controlled according to the determined time to provide a 3D time view of the determined time as the 3D image using the modulated directional lightbeams.
