20080266245 | ELECTROPHORETIC DISPLAYS WITH CONTROLLED AMOUNTS OF PIGMENT - An electrophoretic medium has walls defining a microcavity containing an internal phase. This internal phase comprises electrophoretic particles suspended in a suspending fluid and capable of moving therethrough upon application of an electric field to the electrophoretic medium. The average height of the microcavity differs by not more than about 5 μm from the saturated particle thickness of the electrophoretic particle divided by the volume fraction of the electrophoretic particles in the internal phase. | 10-30-2008 |

20090174651 | ADDRESSING SCHEMES FOR ELECTRONIC DISPLAYS - 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. | 07-09-2009 |
20100103502 | METHODS FOR ACHIEVING IMPROVED COLOR IN MICROENCAPSULATED ELECTROPHORETIC DEVICES - A method for manufacturing a full color, reflective display includes the steps of depositing a first plurality of electrophoretic display elements in substantial registration with a first electrode and a second plurality of electrophoretic display elements in substantial registration with a second electrode. The electrophoretic display elements include a capsule containing a species of particles dispersed in a suspending fluid. The selective deposition of the display elements can be achieved by ink-jet printing methods, screen printing methods or other printing methods. In some embodiments the electrodes are printed onto the substrate before selective deposition of the display elements, while in other embodiments the substrate is provided having the electrodes already disposed on it. In still other embodiments, the sequence of printing of electrodes and electrophoretic display elements can be varied. | 04-29-2010 |

20100201651 | APPARATUS FOR DISPLAYING DRAWINGS - A first apparatus for displaying drawings comprises a housing having an aperture, a drawing sheet comprising electro-optic material movable through the aperture between closed and open positions, and a writing device for writing on the sheet as it moved between its closed and open positions. A second apparatus comprises a display member having a viewing surface, support means for supporting this display member above a floor, an electro-optic medium disposed on the display member, and a movable writing head for writing on the electro-optic medium. Another display comprises an optic medium with two display states visible through a viewing surface. A touch screen is disposed on the opposed side of the optic medium from the viewing surface, and the optic medium is deformable such that pressure applied to the viewing surface will be transmitted to the touch screen. | 08-12-2010 |
20110187683 | ELECTRO-OPTIC DISPLAYS WITH SINGLE EDGE ADDRESSING AND REMOVABLE DRIVER CIRCUITRY - An edge-addressable electronic display is provided including a row electrode in electric communication with a first termination and a column electrode in electric communication with a second termination. The row and column electrodes intersect at a pixel. Both the first and second terminations are disposed proximate to a first edge of the display, and as a result, the pixel may be addressed along the first edge of the display. The display may further include a removable driver circuitry for addressing the pixel in electric communication with at least one of the first and second terminations. | 08-04-2011 |
