Appl. No.:

12/117974

Inventors:

Jonathan D. Albert - Philadelphia PA, US
Barrett Comiskey - Shanghai, CN
Joseph M. Jacobson - Newton Centre MA, US
Libing Zhang - Sharon MA, US
Andrew Loxley - Philadelphia PA, US
Robert D. Feeney - Scituate MA, US

Assignee:

E Ink Corporation - Cambridge MA

International Classification:

G02B 26/00
G09G 3/34

US Classification:

359296, 345107

Abstract:

Novel addressing schemes for controlling electronically addressable displays include a scheme for rear-addressing displays, which allows for in-plane switching of the display material. Other schemes include a rear-addressing scheme which uses a retroreflecting surface to enable greater viewing angle and contrast. Another scheme includes an electrode structure that facilitates manufacture and control of a color display. Another electrode structure facilitates addressing a display using an electrostatic stylus. Methods of using the disclosed electrode structures are also disclosed. Another scheme includes devices combining display materials with silicon transistor addressing structures.

International Classification:

G02B 26/00

US Classification:

359296000

Abstract:

Disclosed herein are novel electrophoretic displays and materials useful in fabricating such displays. In particular, novel encapsulated displays are disclosed. Particles encapsulated therein are dispersed within a suspending, or electrophoretic, fluid. This fluid may be a mixture of two or more fluids or may be a single fluid. The displays may further comprise particles dispersed in a suspending fluid, wherein the particles contain a liquid. In either case, the suspending fluid may have a density or refractive index substantially matched to that of the particles dispersed therein. Finally, also disclosed herein are electro-osmotic displays. These displays comprise at least one capsule containing either a cellulosic or gel-like internal phase and a liquid phase, or containing two or more immiscible fluids. Application of electric fields to any of the electrophoretic displays described herein affects an optical property of the display.

Filed:

Jul 16, 1979

Appl. No.:

6/057879

Inventors:

Larry W. Becker - Wilmington DE

Ian D. Morrison - Webster NY

Assignee:

Betz Laboratories, Inc. - Trevose PA

International Classification:

C02F 514

US Classification:

210699

Abstract:

The present disclosure is directed to oligomeric phosphonic acid derivatives which possess excellent chlorine resistance and acceptable calcium tolerance and which, at substoichiometric amounts, inhibit the formation of scale in aqueous mediums. Additionally, the oligomers have been found to be quite active as dispersants for particulate matter contained in an aqueous medium.
