HEAD-MOUNTED DISPLAY AND OPTICAL ENGINE THEREOF
First Claim
1. An optical engine for a head-mounted display capable of forming images before man'"'"'s eyeballs to be watched, comprising:
- a first polarizer;
a light source emitting rays toward the first polarizer;
an LCoS device for generating the images and reflecting reflective rays from the first polarizer to penetrate the first polarizer;
a concave mirror; and
a beam splitter for refracting the rays of the images having penetrated the first polarizer to the concave mirror, which then magnifies the images and projects the magnified images on the beam splitter to be watched.

Abstract
A head-mounted display comprises monocular or binocular display chambers. Each display chamber is equipped with an optical engine that displays images. The mechanism of the optical engine is as follows: cast rays from a light source onto an LCoS device through a first polarizer, and an image is formed with rays, which reflect off the bottom of the LCoS device. The reflective rays penetrate the first polarizer and a film-coated beam splitter. With a concave mirror, the image is magnified and projected onto the surface of the beam splitter. Finally, the magnified image is formed in a viewer'"'"'s eyeballs by means of the beam splitter.
