Color display device
First Claim
1. A display apparatus comprising:
- a prismatic structure having a front end, a back end, an interior space, an axis J intercepting both said front and said back ends, at least one sidewall in a plane extending between said front and said back ends, said at least one wall comprising a reflective inner surface in said interior space, and an interior space outer perimeter in a plane substantially perpendicular to said axis;
a radiation emitter adapted to emit radiation having a desired wavelength spectrum; and
a viewing window comprising a diffuse display surface located at the front end of the prismatic structure.

Abstract
A color display apparatus and method for displaying colors using radiation sources uses displays that may include multiple radiation sources, a display surface and control hardware and software that enable accurate and reproducible color display. Another apparatus provides means for generating colors upon request and communicating digital information regarding the generation of the color spectrum to local or remote display devices. The apparatus may be used in selecting and ordering colors subject to supplier constraints. Methods for displaying colors and enabling display of the colors in remote locations, as well as methods for conducting business by communicating the color display information are all provided.

18. A display apparatus comprising:
-
a light-conducting sheet having a periphery, a center, a back side, and a front side; and
a plurality of radiation sources distributed about the periphery of the sheet and adapted to emit radiation toward the center, wherein the back side of the sheet has a roughness sufficient to reflect the radiation toward a display surface on the front side of the sheet. - View Dependent Claims (19, 20, 21, 22)

23. A display apparatus having a front and a back, and comprising:
-
a first reflector in the back of the display having a concave, reflective inner surface symmetrical about a first plane and having a first effective diameter;
a second reflector in the front of the display having a concave, reflective inner surface symmetrical about the first plane and facing the first reflector, the second reflector having a second effective diameter smaller than the first effective diameter;
a viewing window in the second reflector at the front of the device;
a convex, reflective impinging surface mounted at the back of the first reflector facing the second reflector and symmetrical about the first plane; and
one or more radiation sources positioned in an annular region between the first reflector and the second reflector and adapted to emit radiation toward the first reflector, the radiation reflecting off of the first reflector and optionally off of the impinging surface, toward the second reflector and ultimately to the viewing window. - View Dependent Claims (24, 25, 26)

27. A display apparatus comprising:
-
at least a partial outer sphere having a polar axis of rotation and a reflective inner surface;
at least a partial inner sphere mounted at least partially within the outer sphere along the polar axis, the inner sphere having a reflective inner surface and a reflective outer surface, forming a radiation path between the reflective outer surface of the inner sphere and the reflective inner surface of the outer sphere;
a plurality of radiation sources adapted to introduce one or more beams of radiation into the radiation path;
a viewing window extending through the outer sphere to the inner sphere and located along the polar axis, the viewing window surrounded by a sidewall extending from the outer sphere to the inner sphere, the sidewall having an inner reflective surface bordering the radiation path;
a transparent radiation entry portal in the inner sphere adjacent the viewing window for allowing radiation to enter the inner sphere from the radiation path; and
a display surface located in the viewing window substantially perpendicular to the polar axis. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36)
