Patent number: 7545358Abstract: An electro-optic display comprises a bistable electro-optic medium, a plurality of pixel electrodes, with associated non-linear elements, and a common electrode, disposed on opposed sides of the electro-optic medium. The display has a writing mode, in which at least two different voltages are applied to different pixel electrodes, and a non-writing mode in which the voltages applied to the pixel electrodes are controlled so that any image previously written on the electro-optic medium is substantially maintained. The display is arranged to apply to the common electrode a first voltage when the display is in its writing mode and a second voltage, different from the first voltage, when the display is in its non-writing mode.Type: GrantFiled: March 1, 2006Date of Patent: June 9, 2009Assignee: E Ink CorporationInventors: Holly G. Gates, Karl R. Amundson

Publication number: 20090000729Abstract: An electro-optic display is produced using a sub-assembly comprising a front sheet, an electro-optic medium; and an adhesive layer. An aperture is formed through the adhesive layer where the adhesive layer is not covered by the electro-optic medium, and the sub-assembly is adhered to a backplane having a co-operating member with the aperture engaged with a co-operating member, thus locating the sub-assembly relative to the backplane. In another form of electro-optic display, a chip extends through an aperture in the electro-optic medium and adhesive layer. In a third form, the aforementioned sub-assembly is secured to a backplane and then a cut is made through both backplane and sub-assembly to provide an aligned edge.Type: ApplicationFiled: June 27, 2008Publication date: January 1, 2009Applicants: E INK CORPORATION, POLYMER VISION LTD.Inventors: Guy M.

Patent number: 7202847Abstract: A method and system for applying addressing voltages to pixels of a display involves receiving input data. The input data includes an indication of an addressing voltage impulse to be applied to a pixel via an electrode. One or more voltage sources are selected, to provide the addressing voltage impulse. The one or more voltage sources each have a pre-selected voltage. The selected one or more voltage sources are electrically connected to an electrode to apply the addressing voltage impulse to the pixel.Type: GrantFiled: June 27, 2003Date of Patent: April 10, 2007Assignee: E Ink CorporationInventor: Holly G.

Patent number: 6704133Abstract: A display overlay includes a contrast media layer and a photoconductive layer disposed between two electrodes. Light from an emissive display strikes the photoconductive layer and lowers the impedance of the photoconductive layer at the point at which the light is incident. Voltage applied to the electrodes creates an electric field that addresses the contrast media layer in locations of reduced impedance.Type: GrantFiled: August 30, 2002Date of Patent: March 9, 2004Assignee: E-Ink CorporationInventors: Holly G.
