Light emissive display based on lightwave coupling in combination with visible light illuminated content
First Claim
1. A display comprising:
- a waveguide, said waveguide comprising a medium with a photoluminescent image which is at least one of printed, coated or mounted thereon;
a first light source associated with said waveguide, said first light source adapted to transmit light at a wavelength less than 450 nm through said waveguide, causing said photoluminescent image to emit visible light;
a second light source; and
a light filter positioned between said waveguide and at least one of a medium and a physical object;
wherein said second light source is adapted, when illuminated, to make visible a second image through said light filter of said display,wherein the second image is at least one of provided on the medium or provided by the physical object.

Abstract
A display with a first emissive image and a second image. The display includes a waveguide that includes an image formed from photoluminescent dyes on a surface of the waveguide which is activated by a first light source. A second light source behind said waveguide produces a second image. A light filter is positioned between the waveguide and the second light source. The second light source can illuminate a transparency, such as a translight, or a physical object providing an image that is viewable from the display when the second light source is illuminated and the first light source is not illuminated. The first image is viewable when the first light source associated with the waveguide is activated, emitting, for example, an ultraviolet light that activates the photoluminescent dyes, causing the first image to be viewable. The light filter behind the waveguide enhances the quality of the emissive image and prevents the image on the transparency or the physical object from being seen when the second light source is not illuminated.

24. A display having a display face providing a view of displayed images, the display comprising:
-
a waveguide; and a photoluminescent image optically coupled to said waveguide; a first light source associated with said waveguide, said first light source adapted to transmit light through said waveguide, causing said photoluminescent image to emit visible light; a second light source adapted, when activated, to illuminate at least one of a medium and a physical object such that a second image is visible at the display face of the display, wherein the second image is at least one of provided on the medium or provided by the physical object; wherein the waveguide is positioned between the display face of the display and at least one of the medium or the physical object; and a light filter positioned between said waveguide and at least one of the medium or the physical object. - View Dependent Claims (25, 26, 27, 28)

29. A display case comprising:
-
a case configured to display a physical object; and a display comprising; a waveguide including a medium with a photoluminescent image which is at least one of printed, coated and mounted thereon; a first light source associated with said waveguide, said first light source configured to transmit light through said waveguide, causing said photoluminescent image to emit visible light; a second light source; and a light filter positioned between said waveguide and at least one of a medium or a physical object; wherein said second light source is positioned and configured, when illuminated, to make visible a second image through said light filter of said display, wherein the second image is at least one of provided on the medium or provided by the physical object. - View Dependent Claims (30)
