US Patent:

57402965, Apr 14, 1998

Filed:

Sep 5, 1996

Appl. No.:

8/708650

Inventors:

Laura Lee Harris - Eugene OR

Assignee:

Inwave Corporation - Eugene OR

International Classification:

G02B 606

US Classification:

385116

Abstract:

A lightweight display system (10) includes a display matrix (22) of output terminals (28) of optical conductors (30) supported on a preferably flexible substrate (16) by terminal housings (20). Each terminal housing (20) has a tubular neck (64) that curves away from its base (62) through a variety of angles. The curvature of the tubular neck (64) includes a full spectrum of angles employed to compensate for curvature occurring in any predetermined or unknown shape of a display screen (12). The necks (64) can be manually or machine cut at the appropriate position (132, 134, 136, 138) on the tubular neck (64) to compensate for the off-axis position of the base (62) with respect to the viewing axis. One embodiment is manufactured in halves (110) that can be joined together, and another embodiment includes friction bumps (69) to secure an optical conductor (30) within tubular neck (64). This low-cost means for directing output from an optical conductor (30) and particularly from an array of optical conductors (30) protruding from a nonplanar screen (122) preserves the quality of an image emitted from such a screen (122).

International Classification:

G09G 334

US Classification:

345 55

Abstract:

A lightweight display system (10) includes an output matrix (34) of output terminals (28) of optical conductors (30) supported on a preferably flexible substrate (16) by terminal housings (20). Optical conductors (30) are collated into an input matrix (34) that receives light containing a source image (39) from projector (40). Light propagates through optical conductors (30) and exits output terminals (28) to form an enlarged display image (31) that corresponds to the source image. Preferred embodiments of display screen (12) are collapsible and facilitate transportation and reassembly.

International Classification:

G09G 334

US Classification:

Abstract:

A reflector assembly (60) for a fiber-optic matrix display system (10) designed to improve the coupling efficiency of luminous energy between a light emitting element (52) and an input matrix (26) and to provide one or more input matrices (26) with substantially uniform illumination over their respective surfaces. The reflector assembly (60) preferably includes an input aperture for receiving luminous energy from the light emitting element (52); a larger output aperture (70) through which the luminous energy exits the reflector assembly (60) to impinge on the imaging medium and the input terminals (28) of the input matrix (26); and a reflector head (64) positioned between the input aperture (68) and the output aperture (70) and having a right rectangular pyramidal, hollow frustum shape preferably designed according to the formula ##EQU1## where n. sub. 1 is the refractive index of optical conductor cores 82, n. sub. 2 is the refractive index of optical conductor claddings 84, and. THETA. sub.
