US 11,231,589 B2 · Ultralight wearable display device

Abstract

Techniques for reducing weight on wearable display devices are described. In one embodiment of the present invention, a wearable display device includes no electronic components and is coupled to an enclosure by a transmission line including only one or more optical fibers, where the fiber is responsible for transporting the content or an optical image from one end of the optical fiber to another end thereof by total internal reflections within the fiber. The optical image is picked up by a focal lens from a microdisplay in the enclosure. The optical image is in lower resolution but received by the optical fiber at a twice speed as the normal refresh rate (e.g., 120 Hz vs. 60 Hz). Two successive images in lower resolution are combined at or near the other end of the optical fiber to generate a combined image at higher resolution, where the combined image is refreshed and perceived at the normal refresh rate.

Dependent claims

A display device comprises:

an eyeglasses frame;
at least one integrated lens including a light waveguide, wherein the integrated lens is framed in the eyeglasses frame;
at least one temple attached to the eyeglasses frame;
and
a set of optical fibers having a first end and a second end, the first end receiving a sequence of two-dimensional (2D) optical images projected thereon from a lens deposed before the second end, wherein the 2D optical images are sequentially transported to the second end by total internal reflection within the optical fibers, wherein no other power-driven electronic components are needed in the display device to receive the 2D optical images, deliver the 2D optical images to the integrated lens, and form the 2D optical images in the light waveguide by a viewer looking at the integrated lens.
