Abstract
A laminated glazing includes a first glass sheet having first and second opposing surfaces, a second glass sheet having third and fourth opposing surfaces, an interlayer between the first glass sheet and the second glass sheet, wherein the interlayer is positioned between the second surface of the first glass sheet and the third surface of the second glass sheet, a p-polarized light reflective layer, and an opaque layer, wherein the p-polarized light reflective layer is positioned between a vehicle interior and the opaque layer when the laminated glazing is installed in a vehicle.
Claims13
A laminated glazing, comprising:
- a first glass sheet having first and second opposing surfaces;
- a second glass sheet having third and fourth opposing surfaces;
- an interlayer between the first glass sheet and the second glass sheet, wherein the interlayer is positioned between the second surface of the first glass sheet and the third surface of the second glass sheet;
- a p-polarized light reflective layer between the first glass sheet and the second glass sheet;
- and
- an opaque layer,
- wherein the p-polarized light reflective layer is positioned between a vehicle interior and the opaque layer when the laminated glazing is installed in a vehicle,
- wherein the p-polarized light reflective layer is in an area overlapping with the opaque layer to provide a display surface, such that the opaque layer is a background for the display surface,
- wherein the opaque layer is on the p-polarized light reflective layer and wherein the opaque layer is on the first glass sheet.
A head-up display system, comprising:
- a laminated glazing, comprising:
- a first glass sheet having first and second opposing surfaces,
- a second glass sheet having third and fourth opposing surfaces,
- an interlayer between the first glass sheet and the second glass sheet, wherein the interlayer is positioned between the second surface of the first glass sheet and the third surface of the second glass sheet,
- a p-polarized light reflective layer between the first glass sheet and the second glass sheet, and
- an opaque layer,
- wherein the p-polarized light reflective layer is positioned between a vehicle interior and the opaque layer when the laminated glazing is installed in a vehicle, and
- wherein the p-polarized light reflective layer is in an area overlapping with the opaque layer to provide a display surface, such that the opaque layer is a background for the display surface;
- wherein the opaque layer is on the p-polarized light reflective layer;
- wherein the opaque layer is on the first glass sheet;
- and
- a projector for projecting p-polarized light toward the p-polarized light reflective layer of the laminated glazing, wherein an image is produced as a virtual image from a reflection of the p-polarized light at the p-polarized light reflective layer.
