Abstract
An electrochromic device is structured to include multiple independently controllable electrochromic regions which can be independently controlled to switch to different transmission levels. One of the electrochromic regions is isolated from any direct electrical connection with any electrodes, and one or more other electrochromic regions interpose an indirect electrical connection between one or more electrodes and the isolated electrochromic region. The electrochromic device can be structured to include multiple independently controllable electrochromic regions, based at least in part upon segmentation of the conductive layers into separate segments to establish the various electrochromic regions.
