1. An electrochromic device, comprising:
an optically active layer having a transmissivity that is alterable by application of electrical power to the optically active layer;
a conductive layer that is disposed directly on the optically active layer on a first side of the optically active layer;
and
a patterned conductive layer that is disposed directly on the conductive layer and that defines electrochromic cells within the optically active layer,
wherein the patterned conductive layer is configured to supply electrical power to the electrochromic cells individually, such that when a first amount of electrical power that is delivered to a first one of the electrochromic cells differs from a second amount of electrical power that is delivered to a second one of the electrochromic cells, varying transmissive states are produced within the optically active layer.
