## Abstract

The present invention provides a woven textile projection display screen including a projection display region wherein the projection display region has two or more interwoven yarns and each yarn in the projection display region includes metal. The projection display region is optically transparent in use. The invention further includes a projection apparatus including the woven textile projection display screen and one or more projectors.

## Claims

### Claim 1

A woven textile projection display screen comprising
a projection display region on a projection display side of the display screen, wherein
the projection display region has two or more interwoven yarns and each yarn in the projection display region includes metal, and wherein
the projection display region is, in use, optically transparent.

### Claim 2 (depends on 1)

The woven textile projection display screen of claim 1 wherein each yarn in the projection display region includes a metal coating or plating.

### Claim 3 (depends on 1)

The woven textile projection display screen of claim 1 wherein the metal is silver metal.

### Claim 4 (depends on 1)

The woven textile projection display screen of claim 1 wherein the textile material of the projection display region comprises a bobbinet weave.

### Claim 5 (depends on 1)

The woven textile projection display screen of claim 1 wherein the projection display region consists of nylon yarns.

### Claim 6 (depends on 1)

A projection apparatus comprising the woven textile projection display screen of claim 1 and further comprising one or more projectors.

### Claim 7 (depends on 6)

The projection apparatus of claim 6 wherein the projection apparatus is a polarised 3D projection apparatus and the one or more projectors comprises one or more polarising filters.

### Claim 8 (depends on 7)

The projection apparatus of claim 7 wherein there are two projectors and each of those projectors comprises a polarising filter, and wherein the filters provide the light from the two projectors with different polarisation.

### Claim 9 (depends on 7)

The projection apparatus of claim 7 wherein the polarising filters are linear or circular polarising filters.

### Claim 10 (depends on 7)

The projection apparatus of claim 7 further comprising glasses for wearing by the viewer of the display screen, wherein the glasses comprise polarising filters which correspond to the type and orientation of the polarisation of the projected light.

### Claim 11 (depends on 6)

The projection apparatus of claim 6 wherein the projection display screen further comprises a bar or truss attached thereto for suspending the screen.

### Claim 12 (depends on 6)

The projection apparatus of claim 6 wherein the one or more projectors is one or more DLP or LCD projectors.

### Claim 13 (depends on 1)

A method of representing images comprising
projecting light from one or more projectors onto a projection display region of the woven textile projection display screen of claim 1.
