Abstract
Several embodiments in accordance with the invention are disclosed. In one particular embodiment, a display screen for a display is discussed.
Claims22
A display comprising:
- a back plane layer;
- an emissive pixel layer;
- a holographic film layer;
- and a cover plate layer;
- said layers being combined to form a display screen having a structure so that at least some light is emitted from the emissive pixel layer into the ambient environment;
- said holographic film layer including patches of holographic film having a front and back side, the front side of the holographic film patches facing the cover plate layer and adjacent structures formed thereon to trap at least some incident light therebetween.
3 more elements
A method of trapping at least a portion of light scattered by an inside face of a cover plate of a display comprising:
- absorbing at least some of the scattered light incident on the front side of a holographic film;
- and
- reflecting the remaining scattered light incident on the front side of the holographic film in a manner so as to be again incident upon the front side of the holographic film after reflection.
A film layer for a display, comprising:
- a holographic film;
- said holographic film having a front and back side;
- the front side of the holographic film having adjacent structures formed therein to trap at least some incident light therebetween,
- wherein the adjacent structures comprise at least one of the following:
- moth-eye-like shaped structures, pyramid-like shaped structures, and pillar-like shaped structures.
2 more elements
A method of trapping at least a portion of light incident upon the front side of a holographic film comprising:
- absorbing at least a portion of the incident light on the front side of the holographic film;
- and
- reflecting the remaining incident light in a manner so as to be again incident upon the front side of the holographic film after reflection.
An article comprising:
- a back plane, emissive pixels, holographic film patches, and a cover plate combined in layers to form a display screen having a structure so that at least some emitted light is transmitted into the ambient environment and so that at least some light propagating within a layer that includes emissive pixels is absorbed by one or more of said holographic film patches.
