Appl. No.:

10/608941

Inventors:

Winthrop D. Childers - San Diego CA, US
Michael A. Pate - Tuscon AZ, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G03B021/14

US Classification:

353 31, 353 37, 353 85, 353 94

Abstract:

A concentrated beam source for a projector includes a plurality of individually addressable light sources configured in a two-dimensional array and a beam concentrator. The beam concentrator is configured to receive light from the plurality of light sources and to produce a reduced beam of collimated light having a component representative of each light source. The reduced beam has cross-sectional dimensions smaller than cross-sectional dimensions of the two-dimensional array.

G03B021/14

US Classification:

353 31, 353 84, 348743

Abstract:

A method of producing a light beam for a display system includes generating a light beam having a transverse cross section that is elongate along a longitudinal axis, and moving a plurality of beam-modifying optical elements sequentially along a travel path that intersects the light beam with the light beam cross-section longitudinal axis oriented transverse to the travel path.

US Classification:

257 72, 257 59, 257432, 257449, 438 69, 438 72, 349 43, 349118, 349138

Abstract:

Optical property normalization for a transparent electrical device is described. In an embodiment, an electrical device includes a plurality of laterally displaced regions that are substantially transparent. Each region of the plurality of regions includes a normalized surface that has an optical property that has a normalized value that is substantially the same, one to another. One of the regions includes a portion of an electrical component. Additionally, at least one of the regions includes beneath the normalized surface an additional surface and a spectral normalization structure. The additional surface has a value for the optical property that is not substantially the same as the normalized value. The spectral normalization structure is disposed with the additional surface such that the normalized surface of the at least one region exhibits the normalized value.

Michael A Pate - Tuscon AZ, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G02B027/14

US Classification:

359634, 359629, 359589, 353 31

Abstract:

A projector projects pixels to form an image in accordance with image data. The projector includes a modulator which modulates light from a light source and outputs projected pixels in a plurality of color spectral bands. The projector has a light source with a non-uniform spectral power distribution with spectral energy within each of the plurality of color spectral bands. A first notch filter removes spectral energy from a first spectral range within a first color spectral band to improve gamut.

Inventors:

Michael Pate - Tucson AZ, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G02B 27/00

US Classification:

359618, 353 37

Abstract:

An optical reflector is positionable between one or more light sources and one or more spatial light modulators (SLM's) within a digital projection system. The optical reflector includes a substrate having a surface to render non-uniform light from the light sources to the SLM's more uniform with one reflection off the substrate, and a number of facets within the surface of the substrate.

International Classification:

G03B 21/28

US Classification:

353 99, 353119

Abstract:

In an implementation, a reflective optical assembly may be configured for translation from a portable position to an operational position. An image forming device may be configured to receive an input of an image and illumination input, provided by a light source, to generate an illuminated image output. The illuminated image output is reflected with the reflective optical assembly to direct the illuminated image output for display.
