20080291129 | METHODS FOR DRIVING VIDEO ELECTRO-OPTIC DISPLAYS - Video displays using relatively low frame rates of about 10 to about 20 frames per second, but having acceptable video quality are described. The displays may use bistable media, and may be driven such that the medium, when driven, changes its optical properties continuously during the driving of each frame. The displays may use an electro-optic medium such that the frame period is from about 50 to about 200 percent of the switching time of the electro-optic medium at the driving voltage used. | 11-27-2008 |
20090109519 | MATERIALS FOR USE IN ELECTROPHORETIC DISPLAYS - An electrophoretic medium comprises an electrophoretic layer, a layer of lamination adhesive and a polymeric layer disposed between the electrophoretic layer and the lamination adhesive layer, the polymeric layer being impermeable to the fluid. A second form of electrophoretic medium has a layer of a complex of an alkali metal and a polymer in contact with the electrophoretic layer. A third form of electrophoretic medium comprises a plurality of discrete droplets of internal phase in a binder, and further comprises a salt. | 04-30-2009 |
20110007381 | 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. | 01-13-2011 |
20120008188 | MULTI-COLOR ELECTRO-OPTIC DISPLAYS - 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. | 01-12-2012 |
20120019898 | 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. | 01-26-2012 |
