Abstract
A transparent chromogenic assembly in which color changes are selectively effectable over predefined areas comprises a pair of facing transparent substrates (15, 21, 28) each covered with a conductive layer divided into individual energizeable areas each provided with a set of busbars (187, 188). A passive layer may be superimposed over one of the substrates, its color being chosen so that the color and the transmissivity of the passive layer accommodates the range of color change and transmissivity of the electrochromic layer to maintain the transmitted color of the panel in a warm or neutral shade. Various other chromogenic windows, devices and systems are also disclosed.
