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 driving two layer variable transmission display

A method for sealing a container having an opening by contacting the opening with a mixture including a phenethylamine and a first polymer, adding a fluid to be contained to the container, and then adding a second mixture, comprising a second polymer, whereupon an interaction between the first and second polymer mixtures result in a seal being formed over the opening, thereby containing the fluid. The first polymer is typically a water-swellable polymer and the second polymer is typically a hydrophilic polymer that will form an interpenetrating network with the swellable polymer.

Multi-color electro-optic displays

A multi-color display device has front and rear electrodes on opposed sides of an electrophoretic medium. The device has a voltage controller configured to apply a first and a smaller second potential difference, of either polarity, between the electrodes. The electrophoretic medium has first, second, and third species of particles of differing colors and charge polarities. The first and second particles move independently of one another in response to the first potential difference, but upon application of the second potential difference form charged aggregates, moving as a unit, having an aggregate color different from the first and second colors.

A multi-color display device has front and rear electrodes on opposed sides of an electrophoretic medium. One of the front and rear electrodes occupies only a minor proportion of a pixel. The device has a voltage control capable of applying a first and a smaller second potential difference of either polarity between the electrodes. The electrophoretic medium has first and second species of particles of differing colors and charge polarities. The first and second particles move independently of one another in response to the first potential difference, but upon application of the second potential difference form charged aggregates, moving as a unit, having an aggregate color different from the first and second colors.
