Patent number: 8728266Abstract: 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: GrantFiled: August 12, 2011Date of Patent: May 20, 2014Assignees: E Ink Corporation, Creator Technology B.V.Inventors: Guy M. Danner, Valerie C. Northrop, Jonathan D. Albert, Holly G. Gates, Erik van Veenendaal, Fredericus J. Touwslager

Patent number: 8633052Abstract: Patterned substrates for photovoltaic and other uses are made by pressing a flexible stamp upon a thin layer of resist material, which covers a substrate, such as a wafer. The resist changes phase or becomes flowable, flowing away from locations of impression, revealing the substrate, which is subjected to some shaping process, typically etching. Portions exposed by the stamp being are removed, and portions that protected by the resist, remain. A typical substrate is silicon, and a typical resist is a wax. Workpiece textures include extended grooves, discrete, spaced apart pits, and combinations and intermediates thereof. Platen or rotary patterning apparatus may be used. Rough and irregular workpiece substrates may be accommodated by extended stamp elements. Resist may be applied first to the workpiece, the stamp, or substantially simultaneously, in discrete locations, or over the entire surface of either. The resist dewets the substrate completely where desired.Type: GrantFiled: April 17, 2009Date of Patent: January 21, 2014Assignees: 1366 Technologies Inc., Massachusetts Institute of TechnologyInventors: Benjamin F. Polito, Holly G. Gates, Emanuel M. Sachs

Patent number: 8558785Abstract: 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.Type: GrantFiled: May 18, 2010Date of Patent: October 15, 2013Assignee: E Ink CorporationInventors: Robert W.

Patent number: 8125501Abstract: 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. The invention also provides a method of driving an electro-optic display which uses an intermediate image of reduced bit depth, and a method of driving an electro-optic display which uses a limited number of differing drive voltages, with higher voltage pulses being used before lower voltage pulses.Type: GrantFiled: April 9, 2007Date of Patent: February 28, 2012Assignee: E Ink CorporationInventors: Karl R. Amundson, Theodore A. Sjodin, Chia-Chen Su, Demetrious Mark Harrington, Holly G. Gates
