Appl. No.:

09/709903

Inventors:

Kevin Day - Phoenix AZ
Andrew R. Slater - Phoenix AZ

Assignee:

Three-Five Systems, Inc. - Tempe AZ

International Classification:

H01L 2904

US Classification:

257 72, 349 44, 349111

Abstract:

Liquid crystal display devices having display screens with an improved black frame is provided. The microdisplay of the LCD is formed of a matrix of pixels disposed on the top surface of a silicon substrate, a layer of glass, and a layer of a reflective metal, preferably aluminum, which is disposed between the silicon substrate and layer of glass. The layer of reflective metal has a pattern, which forms a frame around the matrix of pixels, and is involved in generating the black frame when viewed by the user on the display screen. The reflective material functions to reflect light back to the light generating source, and thus displays a pure black image to the user. In another embodiment, a layer of reflective metal, preferably black chromium, patterned to form a frame around the matrix of pixels, is disposed on the top surface of the glass. The reflective metal layer on top of the glass may be used either in place of, or in addition to, the reflective metal layer on the bottom of the glass to generate the improved black frame.

Terri Cardellino - Chandler AZ, US

International Classification:

G09G005/00

US Classification:

345/156000

Abstract:

The present invention provides a method and apparatus to package and electrically connect a microdisplay that includes a cavity package design. This cavity package design improves the packaging of the microdisplay by using a low number of parts, less processing, and is independent of the customer's interconnect. Structurally, the invention is a unified part, forming a cavity for insertion of a microdisplay cell. Additionally, the cavity package incorporates a variety of test features for ease of testing. Also, the cavity package is a small size and includes multiple mounting options allowing flexibility to customer changes and multiple configurations.

International Classification:

H01Q 300

US Classification:

342359

Abstract:

A user terminal (110) includes a rotating electronically steerable antenna system (210) which combines coarse mechanical beam steering with fine electronic beam steering to provide full hemispherical coverage and enable hand-offs in a satellite communication system. The antenna system (210) comprises at least one antenna unit (and preferably two antenna units) including a mechanically rotatable base (330), an antenna holder (320) coupled to the mechanically rotatable base, and two electronically steerable antenna subunit (310) mounted on the antenna holder. Antenna system (210) also includes an antenna unit controller (260) adapted to control rotation of the mechanically rotatable base (330).
