Abstract
An article for a display device having an output surface. The article includes a light valve, a reflective polarizer, and a diffusing layer. The light valve is configured to be disposed on the output surface of the display device. The light valve is operable in a pass mode and a block mode. The reflective polarizer is disposed on the light valve opposite to the display device. The reflective polarizer is configured to substantially transmit light having a first polarization state and substantially reflect light having an orthogonal second polarization state. The diffusing layer is disposed on the reflective polarizer opposite to the light valve.

An article for a display device having an output surface, the article comprising:
- a light valve configured to be disposed on the output surface of the display device, wherein the light valve is operable in a pass mode and a block mode;
- a reflective polarizer disposed on the light valve opposite to the display device, wherein the reflective polarizer is configured to substantially transmit light having a first polarization state and substantially reflect light having an orthogonal second polarization state;
- and
- a diffusing layer disposed on the reflective polarizer opposite to the light valve.
A display system comprising:
- a display device for generating an image, the display device comprising an output surface;
- an article comprising:
- a light valve disposed on the output surface of the display device, wherein the light valve is operable in a pass mode and a block mode;
- a reflective polarizer disposed on the light valve opposite to the display device, wherein the reflective polarizer is configured to substantially transmit light having a first polarization state and substantially reflect light having an orthogonal second polarization state;
- and
- a diffusing layer disposed on the reflective polarizer opposite to the light valve;
- and
- a controller operable to at least switch the light valve between the pass mode and the block mode.
A method of manufacturing an article for use with a display device having an output surface, the method comprising:
- providing a light valve configured to be disposed on the output surface of the display device, wherein the light valve is operable in a pass mode and a block mode;
- providing a reflective polarizer on the light valve opposite to the display device, wherein the reflective polarizer is configured to substantially transmit light having a first polarization state and substantially reflect light having an orthogonal second polarization state;
- and
- providing a diffusing layer on the reflective polarizer opposite to the light valve.
