HEADS UP DISPLAY SYSTEM
First Claim
1. A heads up display system of a vehicle, comprising:
- a combiner screen comprising;
a first substantially transparent substrate defining a first surface and a second surface;
a second substantially transparent substrate defining a third surface and a fourth surface;
a primary seal disposed between the first and second substrates, wherein the seal and the first and second substrates define a cavity therebetween;
an electro-optic material positioned within the cavity; and
a transflective layer comprising a multilayer polymeric film positioned on one of the first and second surfaces; and
a projector for projecting light having a first polarization toward the first surface of the first substrate.

Abstract
A heads up display system of a vehicle includes a combiner screen having a first substantially transparent substrate defining a first surface and a second surface, a second substantially transparent substrate defining a third surface and a fourth surface. A primary seal is disposed between the first and second substrates. The seal and the first and second substrates define a cavity therebetween. An electro-optic material is positioned within the cavity and a transflective layer having a multilayer polymeric film positioned on one of the first and second surfaces, and a projector for projecting light having a first polarization toward the first surface of the first substrate.

9. A combiner screen for a heads up display, comprising:
-
a first substantially transparent substrate; a second substantially transparent substrate, wherein at least one of the first and second substantially transparent substrate is curved along at least two axes; an electro-optic material positioned between the first and second substantially transparent substrates; and a reflective polarizer laminated to the first substantially transparent substrate, wherein the reflective polarizer comprises a polymeric film. - View Dependent Claims (10, 11, 12, 13)
