Abstract

The present disclosure concerns an encapsulated electrochromic display and a method for encapsulating the same. The method includes forming the electrochromic display on a first encapsulation layer, conditioning the electrochromic display in an environment having a predetermined minimum water vapor therein, and applying a second encapsulation layer on the electrochromic display. The electrochromic display includes at least a first electrode, a second electrode, and an electrochromic layer between the first and second electrodes. At least one of the first and second electrodes is formed by a roll-to-roll printing process and comprises a material having an air or water vapor permeability sufficient to allow water vapor to permeate the electrochromic layer during the roll-to-roll printing process, and at least one of the first and second encapsulation layers is optically transparent. In the encapsulated electrochromic display, the electrochromic layer includes a predetermined minimum amount of water or moisture therein.
