The invention provides an electrophoretic medium comprising at least two types of particles having substantially the same electrophoretic mobility but differing colors. The invention also provides article of manufacture comprising a layer of a solid electro-optic medium, a first adhesive layer on one surface of the electro-optic medium, a release sheet covering the first adhesive layer, and a second adhesive layer on an opposed second surface of the electro-optic medium.

Method of forming an electrophoretic display having a color filter array

Electro-optic displays

A multi-color electrophoretic medium contains first, second and third species of particles. The first species of particles is light-scattering, while the second and third species of particles are transmissive. A method for driving such a display is also described.

Multi-color electrophoretic displays

A multi-color electrophoretic medium contains first, second and third species of particles, the particles having substantially non-overlapping electrophoretic mobilities and bring of three different colors. The particles are dispersed in a fluid having a fourth color. A method for driving such a display is also described.

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.

Electro-osmotic displays and materials for making the same

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.

Multi-color electrophoretic displays and materials for making the same

Electrostatically addressable electrophoretic display

An electronic display comprises an electro-optic material (preferably an electrophoretic medium) having a plurality of pixels, and separate first, second and third sets of addressing means for addressing these pixels. Each of the pixels is associated with one addressing means in each of the three sets, such that addressing of any specific pixel requires application of signals within predetermined ranges to each of the three addressing means associated with the specific pixel being addressed. The display may be in the form of a multi-page electronic book.
