ELECTRO-OPTIC ASSEMBLY
First Claim
1. An electro-optic assembly for use in a vehicle having a windshield, the electro-optic assembly comprising:
- a first arcuate substrate having a first surface with an anti-reflective coating and a second surface;
a second arcuate substrate having a third surface and a fourth surface with an anti-reflective coating, wherein the first and second substrates are positioned such that the second and third surfaces are at least 0.1 mm apart;
a seal disposed between the first and second substrates and located substantially about a periphery of the electro-optic assembly;
an electro-optic medium positioned in a cavity defined by the first substrate, the second substrate, and the seal, the electro-optic medium including a refractive index greater than 1.2; and
wherein the second surface is configured to receive and reflect incident light projected from a projector, thereby displaying information that appears to be displayed forward of the windshield.

Abstract
An electro-optic assembly for use in a vehicle having a windshield is provided and includes a first arcuate substrate having a first surface with an anti-reflective coating and a second surface. A second arcuate substrate includes a third surface and a fourth surface with an anti-reflective coating. The first and second substrates are positioned such that the second and third surfaces are at least 0.1 mm apart. A seal is disposed between the first and second substrates and located substantially about a periphery of the electro-optic assembly. An electro-optic medium is positioned in a cavity defined by the first substrate, the second substrate, and the seal, the electro-optic medium including a refractive index greater than 1.2. The second surface is configured to receive and reflect incident light projected from a projector, thereby displaying information that appears to be displayed forward of the windshield.

16. A heads up display system of a vehicle, comprising:
-
a projector at least partially concealed in a dash of said vehicle; and an electro-optic assembly comprising; a first substrate having a first surface and a second surface, the first surface coated with an anti-reflective coating, including less than 1% reflectance, and the second surface coated with a reflective coating; a second substrate positioned adjacent the first substrate and having a third surface and a fourth surface, the third surface coated with a light transmissive and conductive coating, and the fourth surface coated with an anti-reflective coating; and an electro-optic medium positioned in a cavity defined between the first substrate and the second substrate, wherein a light transmittance of the electro-optic assembly is controlled by varying a potential between the coatings on the second and third surfaces, wherein the electro-optic assembly is configured to reflect incident light projected from the projector in order to display vehicle-related information. - View Dependent Claims (17, 18, 19, 20)
