Matrix Display Assembly Having Multiple Point Lighting

View page
US Patent:
50221710, Jun 11, 1991
Filed:
Jul 16, 1990
Appl. No.:
7/552935
Inventors:
Roy Norfolk - Umatilla FL
Arnold Lazarus - Sayville NY
Assignee:
The Staver Company Inc. - Bay Shore NY
International Classification:
G09F 930
US Classification:
40447
Abstract:
This graphic character matrix display assembly has a support providing a nonreflecting background for a multiplicity of display units arranged for cooperatively displaying the character. Each of the display units comprises a flat display disk having opposite sides. An electromagnet rotates the disk between display position and reversed position. A light source at each disk projects a light beam through a peripheral cutout in the disk when the disk is in display position. The light beam also projects an outline of the disk by backlighting. The periphery of the disk blocks the light beam when the disk is in reversed position. The light source for each disk may be an incandescent lamp, emitting diodes or the end of a light pipe.

Filed:
Aug 28, 1989
Appl. No.:
7/399257
Inventors:
Roy Norfolk - Umatilla FL
Assignee:
The Staver Company - Bay Shore NY
International Classification:
G09F 930
US Classification:
40447
Abstract:
This graphic character matrix display assembly has a support providing a nonreflecting background for a multiplicity of display units arranged for cooperatively displaying the character. Each of the display units comprises a flat display disk having opposite sides. An electromagnet rotates the disk between display position and reversed position. A light source projects a light beam at each disk when the disk is in the display position. The light beam also projects an outline of the disk by backlighting. A tab on each disk projects laterally in the plane of the disk to block the light beam when the disk is in reversed position. The light source may be a single incandescent lamp, plurality of lamps, a light pipe, light emitting diodes or a fiber optic light conduit.
