Abstract

The invention includes many applications for electrochromic devices that require neutral colors and patterned electrodes. It uses novel materials, ways of making the materials, device configurations and applications. In one aspect, the device also includes electrical leads (115,116), transparent conductor layers (135,136), patterned EC layers (143,144), an etch line (99) and a substrate (125).
