Abstract
An optical panel display with one or more signal zones selectively illuminated by a light source such as a light emitting diode light source.
Claims13
A method for constructing a thin profile display with discrete signal zones, the method comprising the steps of:
- providing a chassis with light impenetrable tunnels;
- affixing a plurality of light sources to a substrate sealing an end of the light tunnels, the light sources illuminating the light tunnels;
- covering opposed ends of the light tunnels with a refractor sheet not more than 1 mm thick;
- providing a face plate including a face plate substrate;
- coarse graining a viewable surface of the face plate substrate to measure 2-3 gloss units;
- fine graining a light receiving surface of the face plate substrate to measure 4-6 gloss units;
- forming indicia on the fine grained surface of the face plate substrate;
- and,
- providing for uniformly illuminated indicia by diffusing light emitted from the light sources as it passes through the refractor and the face plate.
6 more elements
A display having a panel-like profile, the display comprising:
- a lighting assembly including
- a chassis with discrete apertures and
- the chassis located between a light source and an inner light diffusing layer;
- a face plate lighted by the lighting assembly;
- the face plate including a second set of apertures;
- and,
- the apertures located between a face plate substrate and the lighting assembly.
4 more elements
A thin profile panel display comprising:
- a face plate and a lighting assembly;
- the face plate including an acrylic substrate with a viewable surface and an opposed non-viewable surface;
- the viewable surface and the non-viewable surface bearing patterns formed during a cell casting process used to form the substrate;
- the gloss of the non-viewable surface exceeding the gloss of the viewable surface;
- indicia formed on the non-viewable surface where only portions of the non-viewable surface bear an opaque coating;
- the lighting assembly including luminous device(s) for illuminating the indicia;
- the face plate engages the lighting assembly to form the thin profile panel display with a thickness not exceeding 0.263 inches;
- and,
- the lighting assembly for illuminating at least portions of the face plate.
6 more elements
A method for constructing a thin profile, dead front display with discrete signal zones, the method comprising the steps of:
- providing a chassis with light impenetrable tunnels;
- affixing a plurality of light sources to a substrate sealing an end of the light tunnels, the light sources illuminating the light tunnels;
- providing a face plate approximately 0.024 inches thick, the face plate including a face plate substrate;
- coarse graining a viewable surface of the face plate substrate to measure 2-3 gloss units;
- fine graining a light receiving surface of the face plate substrate to measure 4-6 gloss units;
- forming indicia on the fine grained surface of the face plate substrate;
- and,
- providing for uniformly illuminated indicia by diffusing light emitted from the light sources as it passes through the face plate.
