| 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 |
| 20100220121 | METHODS FOR DRIVING BISTABLE ELECTRO-OPTIC DISPLAYS, AND APPARATUS FOR USE THEREIN - A bistable electro-optic display has a plurality of pixels, each of which is capable of displaying at least three gray levels. The display is driven by a method comprising: storing a look-up table containing data representing the impulses necessary to convert an initial gray level to a final gray level; storing data representing at least an initial state of each pixel of the display; receiving an input signal representing a desired final state of at least one pixel of the display; and generating an output signal representing the impulse necessary to convert the initial state of said one pixel to the desired final state thereof, as determined from said look-up table. The invention also provides a method for reducing the remnant voltage of an electro-optic display. | 09-02-2010 |
