Display system with extended display area
One embodiment of the present application sets forth an apparatus that includes a composite display layer that transmits a set of composite light. The composite display layer includes a display layer that provides a first subset of light included in the set of composite light, and a first mirror layer parallel to the first display layer that provides a second subset of light included in the set of composite light, where the second subset of light comprises a reflection of a first portion of the first subset of light. The composite display layer also includes a polarizer layer disposed on the composite display layer, where the polarizer layer provides the first portion of the first subset of light to the first mirror layer.
1. An apparatus comprising:
a composite display layer that transmits a set of composite light, the composite display layer including:
a first display layer that provides a first subset of light included in the set of composite light, and
a first mirror layer that resides adjacent to the first display layer within a plane of the composite display layer and provides a second subset of light included in the set of composite light, wherein the second subset of light comprises a reflection of a first portion of light transmitted by the first display layer; and
a polarizer layer disposed on the composite display layer, wherein the polarizer layer provides the first portion of the light transmitted by the first display layer to the first mirror layer.
2. The apparatus of claim 1 , further comprising a film layer interposed between the polarizer layer and the first mirror layer, wherein the film layer retards the first portion of the first subset of light provided to the first mirror layer.
3. The apparatus of claim 2 , wherein the film layer is interposed between the polarizer layer and at least a portion of the first display layer.
4. The apparatus of claim 2 , wherein the polarizer layer comprises a quarter-wavelength circular polarizer and the film layer comprises a quarter-wavelength retardant film layer.
5. The apparatus of claim 1 , wherein:
the set of composite light comprises a set of circularly-polarized waves,
the first portion of the first subset of light comprises a set of p-polarized waves provided by the polarizer layer to the first mirror layer, and
the second subset of light comprises a set of s-polarized waves that are generated when the first portion of the first subset of light is reflected by the first mirror layer.
6. The apparatus of claim 1 , wherein the polarizer layer comprises:
a polarized portion that is disposed over at least the first mirror layer; and
a window portion that is disposed over at least a portion of the first display layer.
7. The apparatus of claim 1 , wherein the polarizer layer comprises a circular polarizer that includes a stack of two or more polarized layers.
8. The apparatus of claim 1 , wherein the composite display layer further comprises a second mirror layer parallel to the first display layer and the first mirror layer, and the first display layer is interposed between the first mirror layer and the second mirror layer.
