## Abstract

A reflective structure with transparent and semi-transparent transmission regions and includes a first transparent layer with a textured area, a reflective layer disposed below the first transparent layer and having a portion that is substantially conformal with at least a first portion of the textured area, and a second transparent layer disposed below the reflective layer and having a portion with a refractive index that is substantially equal to a refractive index of the first transparent layer. The transparent transmission region is configured to transmit a portion of light without substantial deviation, and the semi-transparent transmission region is configured to transmit another portion of the light from the first transparent layer with substantial deviation.

## Claims

### Claim 1

A reflective structure with transparent and semi-transparent transmission regions and comprising:
a first transparent layer having an inner surface, the inner surface including a textured area;
a reflective layer disposed below the first transparent layer and having a first portion that is substantially conformal with at least a first portion of the textured area; and
a second transparent layer disposed below the reflective layer and having a first portion with a refractive index that is substantially equal to a refractive index of the first transparent layer;
wherein the reflective layer is to reflect a first portion and of light from the first transparent layer,
wherein the transparent transmission region encompasses the first portion of the reflective layer and the first portion of the second transparent layer and is configured to transmit a second portion of the light from the first transparent layer without substantial deviation, and
wherein the semi-transparent transmission region encompasses a second portion of the reflective layer and a second portion of the second transparent layer and is configured to transmit a third portion of the light from the first transparent layer with substantial deviation.

### Claim 2 (depends on 1)

The reflective structure of claim 1 wherein the second portion of the second transparent layer has a refractive index that differs from the refractive index of the first transparent layer.

### Claim 3 (depends on 2)

The reflective structure of claim 2 wherein the second portion of the reflective layer is substantially conformal with at least a second portion of the textured area, and wherein the second portion of the second transparent layer has an inner surface along the second portion of the reflective layer.

### Claim 4 (depends on 1)

The reflective structure of claim 1 wherein the second portion of the reflective layer is substantially non-conformal with at least a second portion of the textured area.

### Claim 5 (depends on 1)

The reflective structure of claim 1 wherein the second portion of the second transparent layer has a refractive index that is equal to the refractive index of the first transparent layer.

### Claim 6 (depends on 1)

The reflective structure of claim 1 wherein the second portion of the second transparent layer is electrically switchable to cause the refractive index to selectively match or mismatch the refractive index of the first transparent layer.

### Claim 7 (depends on 1)

The reflective structure of claim 1 wherein the inner surface of the first transparent layer includes a second area that combines with the textured area to produce a pattern that is visible in reflection.

### Claim 8 (depends on 1)

The reflective structure of claim 1 wherein the reflective layer includes a single layer.

### Claim 9 (depends on 1)

The reflective structure of claim 1 wherein the reflective layer includes a plurality of layers.
