Optical System for Head-Mounted Display - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18332435 Titled 'Optical System for Head-Mounted Display'
Simplified Explanation
The abstract describes a head-mounted display that consists of a display system and an optical system. The optical system uses a catadioptric design with one or more lens elements. In one example, the optical system includes a single lens element with a retarder coating on a curved surface. The retarder can be coated on either a concave or convex surface of the lens element. The optical system components can be made using a direct printing technique, which eliminates the need for adhesive layers and hard coatings. This printing technique also allows for better alignment between the optical system and the display system.
Original Abstract Submitted
A head-mounted display may include a display system and an optical system that are supported by a housing. The optical system may be a catadioptric optical system having one or more lens elements. In one example, the optical system includes a single lens element and a retarder that is coated on a curved surface of the lens element. The retarder may be coated on an aspheric concave surface of the lens element. In another example the retarder may be coated on an aspheric convex surface of the lens element. One or more components of the optical system may be formed using a direct printing technique. This may allow for one or more adhesive layers and one or more hard coatings to be omitted from the optical system. A lens element may be directly printed on the display system to improve alignment between the optical system and the display system.
