Abstract
A method includes projecting a single color illumination light having a first color on a liquid crystal on silicon display device, thereby obtaining a single color image light having the first color from the liquid crystal on silicon display device. The method also includes receiving image light having at least a second color that is different from the first color from a display panel that is different from a liquid crystal on silicon display device and combining the single color image light and the image light for projection toward an eye.
Claims18
A method, comprising:
- projecting a single color illumination light having a first color on a liquid crystal on silicon display device, thereby obtaining a single color image light having the first color from the liquid crystal on silicon display device;
- receiving image light having at least a second color that is different from the first color from a display panel that is not a liquid crystal on silicon display device;
- and
- combining the single color image light and the image light for projection toward an eye, wherein combining the single color image light and the image light includes coupling the single color image light into a waveguide that is optically coupled to the display panel that is different from a liquid crystal on silicon display device.

A device, comprising:
- a liquid crystal on silicon display device configured to receive a single color illumination light having a first color and provide a single color image light;
- a display panel that is not a liquid crystal on silicon display device, the display panel configured to provide image light having at least a second color that is different from the first color;
- and
- a waveguide optically coupled to the display panel that is different from the liquid crystal on silicon display device, the waveguide configured to combine the single color image light and the image light for projection toward an eye, wherein combining the single color image light and the image light includes coupling the single color image light into the waveguide.
