Eletrochromic Display Device

摘要

An electrochromic display devices to display a desired image is taught. The display includes a transparent substrate, deposited with a first electrically conducting layer. At least one electrochromic layer is provided on the first electrically conducting layer. An ionically conducting layer is provided on the electrochromic layer and a piezoresistive layer is provided on the second electrically conducting layer. A third electrically conducting layer is provided on the piezoresistive layer. The electrochromic display device displays image in two different modes. In the first mode, an electrical potential is applied across the first and second electrically conducting layer. In the second mode, an electrical potential is applied across the first and the third electrically conducting layer and simultaneously a pressure is applied on the surface.

1. An electrochromic display device, comprising:
a transparent substrate; a first electrically conducting layer provided on the transparent substrate; at least one electrochromic layer provided on the first electrically conducting layer; an ionically conducting layer provided on the electrochromic layer, wherein the ionically conducting layer is substantially ionically conducting in a perpendicular direction to the plane of the ionically conducting layer and substantially ionically insulating in a parallel direction to the plane of the ionically conducting layer; a pattern defining layer defined on the ionically conducting layer and defining an image, wherein the pattern defining layer is electronically and ionically insulating and comprises one or more of openings; an electrolyte layer provided on the pattern defining layer, wherein the electrolyte layer is in ionic contact with the ionically conducting layer through the one or more openings of the pattern defining layer; and a second electrically conducting layer provided on the electrolyte layer such that applying an electrical potential across the first electrically conducting layer and the second electrically conducting layer causes display of the image defined by the pattern defining layer.
