Patent attributes
An electrochromic device is structured to selectively switch separate regions to separate transmission levels, based at least in part upon different transport rates of different charged electrolyte species in the separate regions. Charged electrolyte species can be introduced in various regions of one or more electrochromic stack layers, including a counter-electrode layer, ion-conducting layer, and electrochromic layer. The charged electrolyte species can have different transport rates, so that a distribution of one species introduced in some regions move between layers and different rates relative another distribution of another species introduced in some regions. A species can be introduced, in one or more regions, in one or more particular distributions associated with a particular transmission pattern to structure the electrochromic device to selectively switch to the particular transmission pattern. Species can be introduced via various processes, including ion implantation, chemical diffusion, etc.
