Abstract
A display system and method uses a display element. The display element can provide linearly polarized light. A wave retarder film can be configured to adjust the phase of the linearly polarized light so that reflections of the linearly polarized light from a surface in the environment of the display are reduced. A first light control layer is configured to constrain the field of view of the display in at least a first direction.
Claims18
A display comprising:
- a display element for providing linearly polarized light;
- a retarder configured to adjust the phase of the linearly polarized light so that reflections of the linearly polarized light from a surface in the environment of the display are reduced;
- a first light control layer configured to constrain the field of view of the display in at least a first direction, wherein a normal direction to the first light control layer is tilted with respect to a normal ray from a surface of the display element;
- and the first light control layer is laminated to a rigid, transparent substrate, the rigid transparent substrate being one of the groups consisting of flat, angled and curved.

A method for making a display assembly, the method comprising:
- providing a retarder above a display element;
- providing the display element above a first light control element, wherein the first light control element is tilted with respect to a main surface of the display element;
- providing the first light control element above a backlight and the light control element is laminated to a rigid, transparent substrate, the rigid transparent substrate being one of the group consisting of flat, angled and curved.
A display assembly, comprising:
- a backlight;
- a first substrate provided above the backlight;
- a second substrate provided above the first substrate;
- a display element between the first substrate and the second substrate;
- an optical retarder above the display element;
- a pair of louver films below the display element, wherein the pair of louver films are tilted with respect to the backlight;
- and the pair of louver films is laminated to a rigid, transparent substrate, the rigid transparent substrate being one of the group consisting of flat, angled and curved.
