ELECTROCHROMATIC DEVICE ( VARIANTS ) AND ELECTROCHROMATIC COMBINATION ( VARIANTS ) Russian patent published in 1998 - IPC

FIELD: electrochromatic devices. SUBSTANCE: proposed electrochromatic devices can be used on surfaces of large area. Device includes layers of optical tuning meant to diminish to minimum interference of light between layers of structure and to obtain maximally uniform optical transparency. Optical tuning makes it also possible to replace transparent conductive oxide layers with thin conductive metal layers which results in decreased total thickness of these devices and in facilitation of production process. EFFECT: facilitated production process. 36 cl, 11 dwg
