Patent ID: 7349156

Claim:
A display device comprising: a screen comprising an optical film having optical characteristics such that the optical film transmits light that is in a first polarized state and reflects light that is in a second polarized state, wherein the optical film has opposite first and second ends and first and second portions at a first end side of the optical film and second end side of the optical film, respectively, and is curved between the opposite ends such that the optical film includes a curved inner surface to face a display observer and a curved outer surface to face away from the display observer, said optical film being curved in a manner such that: (i) the first portion of the optical film transmits light in the first polarized state and reflects light in the second polarized state, and (ii) the second portion of the optical film transmits light in the second polarized state and reflects light in the first polarized state, and wherein the light incident on the curved outer surface at the first portion of the optical film is in the first polarization state and the light incident on the curved outer surface at the second portion of the optical film is in the second polarization state; a first display element which is positioned to face the curved outer surface of the curved optical film at the first portion of the curved optical film; and a second display element which is positioned to face the curved outer surface of the curved optical film at the second portion of the curved optical film; wherein the first and second display elements respectively display first and second distinct sub-images which together constitute an image, wherein sub-light which corresponds to the first sub-image and which is in the first polarization state is incident on the curved outer surface at the first portion of the optical film and transmitted through the optical film to be incident on and reflected by the curved inner surface at the second portion of the optical film, wherein sub-light which corresponds to the second sub-image and which is in the second polarization state is incident on the curved outer surface at the second portion of the optical film and transmitted through the optical film to be incident on and reflected by the curved inner surface at the first portion of the optical film, and wherein the sub-light of the first and second sub-images reflected by the curved inner surface of the optical film is adapted to be incident on right and left eyes of the display observer, respectively.
