Patent ID: 7486341

Claim:
A light weight head mounted visual stereoscopic display device with a large field of view having an image producing system for producing a 3-dimensional visual image seen by a viewer, the image producing system consisting essentially of: for each of a right eye and a left eye of the viewer to provide a spatially distinct image independently to each of the right eye and the left eye, one single planar display screen for displaying plural pixels of an image; one single planar tunable focus liquid crystal micro-lens array having plural liquid crystal micro-lenses each aligned with one of the plural pixels of the one single planar display screen, wherein the plural liquid crystal micro-lenses alternates a diopter of the plural pixels; one single planar black mask having plural apertures aligned with the plural liquid crystal micro-lenses located between the planar tunable focus liquid crystal micro-lens array and the planar display screen to prevent light from passing through the intervals between the plural liquid crystal micro-lenses of the tunable focus liquid crystal micro-lens array corresponding independently to one of the right and the left eye; and a bias lens located between the tunable focus liquid crystal micro-lens array and the eye of the viewer to converge light from each of the plural pixels into a pupil of the eye so that all portions of the displayed image are visible even though the field of view is large and the viewer moves the eye.
