Patent number: 9075280Abstract: An electro-optic display comprises, in order, a backplane comprising a plurality of pixel electrodes; a layer of a solid electro-optic medium; a main adhesive layer; and at least one of a light-transmissive protective layer and a light-transmissive electrically-conductive layer. The electro-optic layer may be in direct contact with the backplane or separated therefrom by a thin auxiliary layer of adhesive. The main adhesive layer may be colored to provide a color filter array. An inverted front plane laminate useful in forming such a display comprises the same layers except that the backplane is replaced by a release sheet. The display combines good low temperature performance and good resolution at higher temperatures.Type: GrantFiled: October 15, 2010Date of Patent: July 7, 2015Assignee: E Ink CorporationInventors: Thomas H. Whitesides, Richard J. Paolini, Jr., Michael D. Walls, Seungman Sohn, Michael D. McCreary, Guy M. Danner, Charles Howie Honeyman, Gregg M. Duthaler, Michael L. Steiner, John E. Ritter
