Abstract

A windshield display system for a vehicle is provided herein and includes a rearview mirror assembly having at least one light source configured to illuminate a location on a windshield. At least one photoluminescent structure is disposed at the location and is configured to luminesce in response to excitation by light emitted from the at least one light source.

First claim

What is claimed is:

1. A windshield display system for a vehicle, comprising:
a rearview mirror assembly having at least one light source configured to illuminate a location on a windshield;
at least one photoluminescent structure disposed at the location and configured to luminesce in response to excitation by light emitted from the at least one light source.

2. The windshield display system of claim 1 , further comprising a light blocking layer disposed at the location and configured to block ultraviolet radiation from entering the vehicle via the location on the windshield.

3. The windshield display system of claim 1 , further comprising a light reflective layer disposed at the location and configured to reflect light incident thereon that is emitted from the at least one photoluminescent structure and is propagating toward the windshield.

4. The windshield display system of claim 1 , further comprising a dark dead layer that hides the at least one photoluminescent structure unless the at least one photoluminescent structure is in a state of luminescence.

5. The windshield display system of claim 1 , wherein the at least one photoluminescent structure conveys information when in a state of luminescence.

6. The windshield display system of claim 1 , further comprising at least one light source coupled to a roof structure of the vehicle and configured to illuminate the location of the windshield illuminated by the at least one light source of the rearview mirror assembly or a separate location of the windshield.

7. The windshield display system of claim 1 , wherein the at least one light source comprises one of an ultraviolet light source, a violet light source, and a blue light source.

8. A windshield display system for a vehicle, comprising:
at least one light source of a rearview mirror assembly disposed proximate an upper portion of the windshield and configured to illuminate a location on a windshield; and
at least one photoluminescent structure disposed at the location and configured to luminesce in response to excitation by light emitted from the at least one light source.

9. The windshield display system of claim 8 , further comprising a light blocking layer disposed at the location and configured to block ultraviolet light from entering the vehicle via the location on the windshield.

10. The windshield display system of claim 8 , further comprising a light reflective layer disposed at the location and configured to reflect light incident thereon that is emitted from the at least one photoluminescent structure and is propagating toward the windshield.

11. The windshield display system of claim 8 , further comprising a dark dead layer that hides the at least one photoluminescent structure unless the at least one photoluminescent structure is in a state of luminescence.

12. The windshield display system of claim 8 , wherein the at least one photoluminescent structure conveys information when in a state of luminescence.

13. The windshield display system of claim 8 , wherein the at least one light source comprises one of an ultraviolet light source, a violet light source, and a blue light source.

14. The windshield display system of claim 8 , wherein the at least one light source is part of a rearview mirror assembly of the vehicle.

15. A windshield display system for a vehicle, comprising:
a first light source configured to emit light in a fixed direction toward a windshield;
a second light source configured to emit light in an adjustable direction toward the windshield; and
at least one photoluminescent structure coupled to the windshield and configured to luminesce in response to excitation by light emitted from at least one of the first light source and the second light source,
wherein one of the first light source and the second light source are a part of a rearview mirror assembly.

16. The windshield display system of claim 15 , wherein the first light source is part of a roof structure of the vehicle.

17. The windshield display system of claim 16 , wherein the second light source is part of the rearview mirror assembly, wherein the direction in which light is emitted from the second light source depends on the position of the rearview mirror assembly.

18. The windshield display system of claim 15 , wherein the at least one photoluminescent structure luminesces in one of a single color and a plurality of colors.

19. The windshield display system of claim 15 , wherein the first light source and the second light source each emit one of an ultraviolet light, a violet light, and a blue light.
