Abstract
Architecture and designs of wearable display devices are described. According to one aspect of the present invention, at least one optical conduit is embedded in or integrated with a temple of the wearable display device. The optical conduit is used to transport an optical image from one end to another end, where the optical image is generated in an image source (e.g., microdisplay) in accordance with image data. The microdisplay is powered and receives the image data and control signals via an active optical cable.
Claims10
A method for transporting an optical image, the method comprising:
- receiving the optical image from an optical cube, wherein the optical image is in a reversed aspect of ratio, the optical cube is attached with a microdisplay device and a light source, the optical image is formed by shining illumination from the light source onto the microdisplay device;
- projecting the optical image into an optical conduit, wherein the conduit includes an array of optical fibers, and is physically rotated by 90 degrees;
- rotating the optical image 90 degrees by transporting the optical image through the optical conduit by total internal reflections within the fibers;
- receiving the optical image in a normalized aspect of ratio before projecting the optical image into an integrated lens for view therein by a viewer.
