Electro-optic displays, and materials and methods for production thereof
First Claim
1. A process for the production of a front plane laminate for use in an electro-optic display, the process comprising:
- forming a sub-assembly comprising a layer of lamination adhesive and a layer of electro-optic medium;
forming an aperture through said sub-assembly; and
thereafter securing to exposed surface of the layer of lamination adhesive of said sub-assembly a light-transmissive electrode layer, the electrode layer extending across the aperture.

Abstract
A front plane laminate (see U.S. Pat. No. 6,982,178) is produced by forming a sub-assembly comprising a lamination adhesive layer and an electro-optic layer, forming an aperture through the sub-assembly, and securing a light-transmissive electrode layer to the sub-assembly so that the electrode layer extends across the aperture. Alternatively, formation of the aperture is omitted, and the electrode layer has a tab portion extending beyond the edges of the lamination adhesive and electro-optic layers. When a front plane laminate is secured to a backplane to form an electro-optic display, a stiffening layer may be attached to either part to increase its stiffness, then removed after the lamination. An electro-optic display or front plane laminate may use an adhesive layer comprising separate layers of cross-linked and non-cross-linked adhesive.

26. A process for forming a flexible electro-optic display, the process comprising:
-
providing a flexible backplane comprising at least one electrode; providing a flexible front plane laminate comprising a flexible light-transmissive electrically-conductive layer;
a flexible layer of a solid electro-optic medium;
a flexible adhesive layer and a release sheet;removing the release sheet from the front plane laminate; and laminating the front plane laminate to the backplane to form an electro-optic display, wherein a stiffening layer is secured to at least one of the front plane laminate and the backplane prior to the lamination, the stiffening layer serving to increase the stiffness of the front plane laminate and/or backplane. - View Dependent Claims (27)
