Abstract

A device for encapsulating and passivating integrated control circuits of flat screens. A sealing bead is placed on a substrate plate in order to encapsulate and passivate an integrated control circuit mounted on the plate. In one embodiment, the sealing bead is placed directly on top of the control circuit. In a second embodiment, the sealing bead is placed on both sides of the circuit so as to form a chamber which is separate from that which contains the active matrix. In a third embodiment, an opaque material is also placed on top of the circuit which acts as a spacer and may also act as a "black matrix".
