  • Publication number: 20230045982
    Abstract: A method of displaying a light field to one or more viewers using a light field display module comprising an optical image generator for generating an optical image and an array of shutters for selectively providing the viewers with partial views of the optical image, the method comprising determining a shutter pattern that ensures no partial views ever overlap, and repeatedly generating the partial views according to the shutter pattern and from a digital representation of the light field, generating the optical image from the partial views, and shifting the shutter pattern, until each viewer's set of partial views comprise a full 3D view.
