Abstract
Provided is a light guide display with a protective layer. The light guide display includes a plurality of aligned magnifying layers providing a viewing surface. Each magnifying layer includes a plurality of light guides, each light guide having an input end, a midsection, and an output end. The plurality of input ends are aligned. The plurality of output ends are aligned. A protective layer is coupled to the aligned output ends. An appropriate method of making a light guide screen with a protective layer is also provided.

A light guide display with protective layer comprising:
- a plurality of aligned magnifying layers providing a viewing surface, each magnifying layer including:
- a plurality of light guides, each light guide having an input end, a midsection and a magnifying output end;
- the plurality of input ends aligned;
- the plurality of magnifying output ends aligned in substantially continuous parallel contact;
- and
- a protective layer coupled to the output ends.
A light guide display with protective layer comprising:
- a plurality of aligned magnifying layers providing a viewing surface, each magnifying layer including:
- a plurality of light guides, each light guide having an input end, a midsection and a magnifying output end;
- the plurality of input ends aligned;
- the plurality of output ends aligned in substantially contiguous parallel contact;
- a louver layer coupled to the aligned magnifying ends;
- and
- a protective layer coupled to the louver layer, opposite from the magnifying ends.
A method of making a light guide display with protective layer comprising:
- providing a plurality of light guides, each light guide having an input end, a midsection and an output end;
- arranging the plurality of light guides into a plurality of magnifying light guide layers, each one light guide thick, the output ends of the light guides in each layer aligned in substantially contiguous parallel contact, each layer providing an input end and an output end;
- aligning the plurality of light guide layer input ends as an input surface;
- aligning the plurality of light guide layer output ends as an output face;
- and
- joining a protective layer to the output face.
A light guide display with protective layer comprising:
- a case
- a plurality of aligned magnifying layers disposed within the case and providing a viewing surface, each magnifying layer including:
- a plurality of light guides, each light guide having an input end, a midsection and a magnifying output end;
- the plurality of input ends aligned as an input surface;
- the plurality of magnifying output ends aligned in substantially contiguous parallel contact;
- at least one image source proximate to the input surface;
- a louver layer coupled to the aligned magnifying output ends;
- and
- a protective layer coupled to the louver layer, opposite from the magnifying output ends.
