US Patent:

46609377, Apr 28, 1987

Filed:

Jun 25, 1984

Appl. No.:

6/623976

Inventors:

Kenneth J. Richardson - Hudson OH

Assignee:

Crystaloid Electronics Company - Hudson OH

International Classification:

G02F 113

US Classification:

350349

Abstract:

A dichroic dye-containing nematic liquid crystal mirror has a photocell connected thereto to automatically change, that is, to dim or brighten, the mirror upon exposure to light. Under the preferred operating conditions, the mirror functions as an ordinary mirror but is dimmed by light. The invention is especially suited for the rearview mirror of an automobile.

Appl. No.:

6/131171

Inventors:

Kenneth J. Richardson - Hudson OH

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

G02F 113

US Classification:

350334

Abstract:

A liquid crystal device for direct display of analog information in images and patterns includes a layer of liquid crystal material sandwiched between a front and a back transparent plate. Transparent conducting films are applied to selected portions of the sides of both front and back transparent plates adjacent to the liquid material. A resistor network is provided electrically continuous with at least one of the transparent conducting films for impressing a voltage gradient transversely across the transparent conducting films so as to permit the selective, incremental reorientation of the liquid crystal material into the desired images and patterns.
