MONOLITHIC ARCHITECTURE AND ELECTROLYTE FOR ELECTROCHROMIC DEVICES

摘要

In a preferred embodiment, each segment of an electrochromic display Is formed In a monolithic stack on a substrate A control element is disposed on the substrate, followed by an insulating layer, a common electrode layer, a reflector layer, and a segment layer having an adsorbed electrochromophore Vertical conductors electrically couple the control element to the two electrodes An electrolyte, which may be a solid or liquid, permeates the monolithic stack and is contained by a frontplane In addition, the electrolyte may be isotropically or anisotropically conductive Vertical insulators separate neighboring segments In an alternative embodiment, the control element is placed on an opposing side of the substrate and is electrically coupled to the monolithic stack by way of a via hole The present invention improves electrochromic display performance by reducing the length of drive elements, and by reducing ionic crosstalk between neighboring segments
