System for providing projected information combined with outside scenery
First Claim
1. A system for producing a display image on a transparent or semi-transparent illuminated surface utilizing external ambient light, wherein said system is comprised of:
- a) a polarizing reflective surface that utilizes external ambient light to project said display image in a selectable direction, andb) at least one light collecting element that collects and directs said external ambient light to said polarizing reflective surface, andc) a display processor for creating said display image, andd) an optical device that accepts light from multiple directions, wherein said optical device selectively reflects polarized light orienting from first direction of the said polarizing reflective surface, and transmits through light orienting from a second direction of outside scenery while controlling the optical properties of the light orienting from the second direction, andwherein said display image of said polarizing reflective surface is projected in said selectable direction such that the orientation of said polarized reflective image is aligned with the orientation of said selectively reflected polarized light orienting from first direction of said optical device that accepts light from multiple directions, andwherein said projected display image of said polarizing reflective surface is utilizing said external ambient light by using said light collecting element in front of said polarizing reflective surface thus eliminating the need for any light illuminated from the back side of the display (“
Backlight”
), andwherein said optical device that accepts light from multiple directions controls the optical characteristics of said light orienting from a second direction of outside scenery and combines this light with said polarized light orienting from first direction of the said polarizing reflective surface to create a combined image.

Abstract
A system for producing a display image on a transparent, semi-transparent or translucent surface, without the need for an integral light source. The system includes a reflective surface that utilizes external light to project the display image in a selectable direction. A light collecting element collects and directs ambient light to the reflective surface. A display processor creates the display image and transmits the image onto an optical device. The optical device that has a reflective polarizer accepts the projected display image. The optical device selectively reflects light of the projected display image, and while controlling the optical properties of the light from second direction it combines the projected display image with the light from the second direction.
