Abstract: An electrostatically controlled blind system for use in limiting the passage of light through windows, doors, and skylights in building structures is disclosed. The blind system comprises a plurality of elongated, electroconductive louvers which are pivotally supported within an electroconductive peripheral frame. The blind system is inserted between sheets of insulated glass having an electroconductive coating and is thereby insulated from the ambient atmosphere. A voltage converter converts alternating current to an electrostatic charge which is distributed on the surface of the louvers causing them to repel each other. The electrostatic charge on the louvers induces an opposite electrostatic charge on the grounded sheets of insulated glass creating an electrostatic force of attraction therebetween.
