Abstract
An optical stack for use with an illuminated data display. The stack comprises the following layers: an opaque layer defining one or more openings therein, a diffuser layer disposed overlying the openings, a fiber optic glass layer overlying the diffuser layer, and transparent protective layer overlying the fiber optic glass layer. An illumination source is disposed within the one or more openings, and illumination from the illumination source propagates from the illumination source through the diffuser layer, through the fiber optic layer, and through the protective layer.
Claims24
An optical stack for use with an illuminated data display, comprising:
- in a stacked relationship:
- an opaque layer defining one or more openings therein;
- a diffuser layer disposed overlying the openings;
