Abstract

In an embodiment, a light emissive window assembly for providing illumination to an occupant compartment of an automobile comprises a window panel comprising a transparent viewing area and an emissive area, wherein the emissive area is configured to emit light into the occupant compartment and the transparent viewing area is not configured to emit light; wherein the emissive area comprises an abrasion resistant layer, an ultraviolet protective layer, a base layer, and an emissive layer; wherein the ultraviolet protective layer is located in between the abrasion resistant layer and the base layer; and wherein the base layer is located in between the ultraviolet protective layer and the emissive layer.

First claim

The invention claimed is:

1. A light emissive window assembly for providing illumination to an occupant compartment of an automobile comprising:
a window panel comprising a transparent viewing area and an emissive area, wherein the emissive area is configured to emit light into the occupant compartment and the transparent viewing area is not configured to emit light;
wherein the emissive area comprises
an abrasion resistant layer,
an ultraviolet protective layer,
a base layer, and
an emissive layer;
wherein the ultraviolet protective layer is located in between the abrasion resistant layer and the base layer; and wherein the base layer is located in between the ultraviolet protective layer and the emissive layer; and

wherein the transparent viewing area comprises a first transparent area separated from a second transparent area by the emissive area which encircles both the first and second transparent areas or wherein the emissive area is in the form of a line located in between a first transparent viewing area and a second transparent viewing area.

2. The light emissive window assembly of claim 1 , further comprising a black out layer located in between the base layer and the emissive layer.

3. The light emissive window assembly of claim 1 , wherein the emissive area encircles the transparent viewing area.

4. The light emissive window assembly of claim 1 , wherein the transparent viewing area comprises the first transparent area separated from the second transparent area by the emissive area which encircles both the first and second transparent areas.

5. The light emissive window assembly of claim 1 , wherein the base layer comprises a polycarbonate, poly(methyl methacrylate), a polyester, glass, or a combination comprising at least one of the foregoing.

6. The light emissive window assembly of claim 1 , wherein the base layer comprises a polycarbonate.

7. The light emissive window assembly of claim 1 , wherein the ultraviolet protective layer has dispersed ultraviolet absorbing additives.

8. The light emissive window assembly of claim 1 , wherein the emissive layer comprises a dielectric layer and a phosphor layer; wherein the dielectric layer is located in between the base layer and the phosphor layer.

9. The light emissive window assembly of claim 1 , wherein the emissive layer comprises a polymer light emitting display, an organic light emitting display, a light emitting diode, or an electroluminescent display.

10. The light emissive window assembly of claim 1 , further comprising a frame coupled to a perimeter of the emissive area.

11. The light emissive window assembly of claim 1 , further comprising a high conductive layer located in between the base layer and the emissive layer; and a low conductive layer; wherein the emissive layer is located in between the high conductive layer and the low conductive layer.

12. The light emissive window assembly of claim 11 , further comprising a voltage source connected to the high conductive layer and the low conductive layer.

13. The light emissive window assembly of claim 11 , wherein one or both of the high conductive layer and the low conductive layer comprises at least one of a conductive ink and a conductive wire.

14. A light emissive window assembly for providing illumination to an occupant compartment of an automobile comprising:
a window panel comprising a transparent viewing area and an emissive area, wherein the emissive area is configured to emit light into the occupant compartment and the transparent viewing area is not configured to emit light;
wherein the emissive area comprises
an abrasion resistant layer,
an ultraviolet protective layer,
a base layer, and
an emissive layer;
a further ultraviolet protective layer and a further abrasion resistant layer;
wherein the ultraviolet protective layer is located in between the abrasion resistant layer and the base layer; and wherein the base layer is located in between the ultraviolet protective layer and the emissive layer; and wherein the further abrasion resistant layer is located on an opposite side of the emissive layer as the abrasion resistant layer; and wherein the further ultraviolet protection layer is located in between the emissive layer and the further abrasion resistant layer.

15. A light emissive window assembly for providing illumination to an occupant compartment of an automobile comprising:
a window panel comprising a transparent viewing area and an emissive area, wherein the emissive area is configured to emit light into the occupant compartment and the transparent viewing area is not configured to emit light;
wherein the emissive area comprises
an abrasion resistant layer;
an ultraviolet protective layer;
a base layer;
a black out layer;
an emissive layer;
a further ultraviolet protective layer; and
a further abrasion resistant layer;
wherein the ultraviolet protective layer is located in between the abrasion resistant layer and the base layer; wherein the base layer is located in between the ultraviolet protective layer and the emissive layer; wherein the black out layer located in between the base layer and the emissive layer; wherein the further abrasion resistant layer is located on an opposite side of the emissive layer as the abrasion resistant layer; and wherein the further ultraviolet protection layer is located in between the emissive layer and the further abrasion resistant layer.

16. The light emissive window assembly of claim 15 , wherein the emissive layer comprises a dielectric layer and a phosphor layer; wherein the dielectric layer is located in between the base layer and the phosphor layer.

17. The light emissive window assembly of claim 15 , further comprising a high conductive layer located in between the base layer and the emissive layer; and a low conductive layer; wherein the emissive layer is located in between the high conductive layer and the low conductive layer.

18. The light emissive window assembly of claim 15 , wherein the emissive layer comprises a polymer light emitting display, an organic light emitting display, a light emitting diode, or an electroluminescent display.

19. The light emissive window assembly of claim 15 , wherein the emissive area encircles the transparent viewing area.
