## Abstract

A textured window film has a prismatic effect that allows a substantial amount of incoming light to pass through a window while refracting the light at random or semi-random angles in a manner that distorts viewed images. The result is a window film that is brighter and more vibrant while also providing visual privacy. The textured window film can therefore better simulate real textured and colored glass.

## Claims

### Claim 1

An apparatus, comprising:
a textured window film, including:
a plurality of light-transmissive layers including:
a vinyl film layer,
a patterned layer formed on a top surface of the vinyl film layer, the patterned layer forming discrete bumps that cover at least some areas of the top surface of the vinyl film layer, wherein the discrete bumps have different sizes, shapes, or spacing to produce different prismatic refraction effects and are grouped based on size or shape into at least a first area having a first prismatic characteristic and a second area having a second prismatic characteristic that is different than the first prismatic characteristic; and
an additional layer disposed over the discrete bumps and over the uncovered areas of the top surface of the vinyl film layer.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein a surface of the additional layer is non-planar.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein the additional layer comprises a resin layer.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the vinyl film layer is between 0.5-10 mils thick and the discrete bumps are approximately 0.5-5.0 mils thick.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein an ink layer is located on the top surface of the vinyl layer.

### Claim 6 (depends on 1)

The apparatus of claim 1, wherein the textured window film comprises a packaged textured window film, wherein the plurality of light-transmissive layers are held onto a packaging layer without adhesive and the plurality of light-transmissive layers is peelingly removable from the packaging layer.

### Claim 7 (depends on 1)

The apparatus of claim 1, wherein the discrete bumps are grouped based on size, wherein one of the first and second areas contains smallest ones of the discrete bumps and the other of the first and second areas contains largest ones of the discrete bumps.

### Claim 8 (depends on 1)

The apparatus of claim 1, wherein the discrete bumps are grouped based on shape, wherein one of the first and second areas contains ones of the discrete bumps having a particular shape and the other of the first and second areas contains ones of the discrete bumps without the particular shape.

### Claim 9

An apparatus, comprising:
a window film product, including:
a packaging layer; and
a plurality of light-transmissive layers held onto the packaging layer without adhesive, the plurality of light-transmissive layers peelingly removable from the packaging layer, the plurality of light-transmissive layers including:
a polymeric film layer and a patterned layer formed on a top surface of the polymeric film layer, the patterned layer forming discrete bumps that cover at least some areas of the top surface of the polymeric film layer, wherein the discrete bumps have different sizes, shapes, or spacing to produce different prismatic refraction effects and are grouped based on size or shape into at least a first area having a first prismatic characteristic and a second area having a second prismatic characteristic that is different than the first prismatic characteristic.

### Claim 10 (depends on 9)

The apparatus of claim 9, further comprising:
an additional light-transmissive layer formed on the plurality of light-transmissive layers, wherein a surface of the additional light-transmissive layer is non-planar.

### Claim 11 (depends on 10)

The apparatus of claim 10, wherein the additional light-transmissive layer comprises a resin layer.

### Claim 12 (depends on 9)

The apparatus of claim 9, wherein the polymeric film layer is between 0.5-10 mils thick and the discrete bumps are approximately 0.5-5.0 mils thick.

### Claim 13 (depends on 9)

The apparatus of claim 9, wherein a surface area of the top surface of the polymeric film layer is greater than a surface area of a planar side of the patterned layer.

### Claim 14 (depends on 9)

The apparatus of claim 9, an ink layer is located on the top surface of the polymeric film layer.

### Claim 15 (depends on 9)

The apparatus of claim 9, wherein one of the first and second areas is contained within a part of the plurality of light-transmissive layers to pass light of a first color.

### Claim 16 (depends on 15)

The apparatus of claim 15, wherein the other of the first and second areas is contained within a part of the plurality of light-transmissive layers to pass light of a second color that is different than the first color.
