Abstract
A multiview 3D wrist watch includes 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 has a direction and an 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.
