An electro-optic display comprising at least two separate layers of electro-optic material, with one of these layers being capable of displaying at least one optical state which cannot be displayed by the other layer. The display is driven by a single set of electrodes between which both layers are sandwiched, the two layers being controllable at least partially independently of one another. Another form of the invention uses three different types of particles within a single electrophoretic layer, with the three types of particles being arranged to shutter independently of one another.

Method for electrophoresis in liquid crystals

Номер: US20120162548A1
Автор: Israel Esteban Lazo-Martinez, Oleg D. Lavrentovich, Oleg P. Pishnyak
Принадлежит: KENT STATE UNIVERSITY

A method of electrophoretic movement of particles through a liquid crystal utilizes a direct (DC) or alternating (AC) electric field that is applied along the liquid crystal director (for liquid crystals with a positive dielectric anisotropy) or perpendicular to the director (for liquid crystals with a negative dielectric anisotropy). A perpendicular or tilted orientation of the liquid crystal molecules at the surface of the particle causes distortions, such that the fore-aft (or left-right) symmetry of the particle is broken. The asymmetric orientation of the liquid crystal around the particle allows both charged and neutral particles to be transported, even when the particles themselves are perfectly symmetric (spherical).

Methods and controllers for driving a light-collimating film including elongated chambers of bistable electrophoretic fluids. The light-collimating films are suitable to control the amount and/or direction of light incident to a transmissive substrate. Such films may be integrated into devices, such as LCD displays, to provide a zone of privacy for a user viewing the LCD display. Because the light-collimating film is switchable, it allows a user to alter the collimation of the emitted light on demand. Because the films are bistable, they do not require additional power after they have been switched to a display state. 1. A method for driving a switchable light-collimating film , a first light-transmissive electrode layer,', 'a collimating layer having a thickness of at least 20 μm, and comprising a plurality of elongated chambers, each elongated chamber having an opening,', 'a bistable electrophoretic fluid comprising pigment particles disposed in each elongated chamber,', 'a sealing layer that seals the bistable electrophoretic fluid within at least one of the plurality of elongated chambers by spanning the opening of the elongated chamber, and', 'a second light-transmissive electrode layer, wherein the first and second light transmissive layers are disposed on either side of the collimating layer,, 'wherein the switchable light-collimating film includesthe method comprising applying a time varying voltage between the first and the second light-transmissive electrode layers.2.

Described herein is a polymorphic display, which is a unitary apparatus constructed such that a wide variety of electro-optic functions are enabled. The polymorphic display is used in an intelligent container system for monitoring and evaluating actions taken at the container system. In this way, relationships between displayed information and actions may be determined. The polymorphic display, even when having multiple pixels, enables sharing of selected structures among the pixels. In a multi-pixel construction, there is a set of pixels in the display that exhibit one set of operable properties, such as particular stability, sequencing, and switching properties, and another set of pixels that are different from the first set. That is, they have different stability, sequencing, or switching properties. In such a way, a highly flexible polymorphic display may be construed to satisfy a wide range of display needs, including novel applications on intelligent container systems.

Method for electrophoresis in liquid crystals

Номер: US20150261023A1
Автор: Israel Esteban Lazo-Martinez, Oleg D. Lavrentovich, Oleg P. Pishnyak
Принадлежит: Individual

A method of electrophoretic movement of liquid droplets/gas bubbles through a liquid crystal utilizes a direct (DC) or alternating (AC) electric field that is applied along the liquid crystal director (for liquid crystals with a positive dielectric anisotropy) or perpendicular to the director (for liquid crystals with a negative dielectric anisotropy). A perpendicular or tilted orientation of the liquid crystal molecules at the surface of the liquid droplet/gas bubble causes distortions, such that the fore-aft (or left-right) symmetry of the liquid droplet/gas bubble is broken. The asymmetric orientation of the liquid crystal around the liquid droplet/gas bubble allows both charged and neutral particles to be transported, even when the liquid droplets/gas bubbles themselves are perfectly symmetric (spherical).
