Abstract
A method for attaching a faceplate and a backplate of a field emission display device. Specifically, one embodiment of the present invention discloses a method for protecting a silicon nitride passivation layer from reacting with a glass frit sealing material that contains lead oxide during an oven sealing or laser sealing process. The passivation layer protects row and column electrodes in the display device. A barrier material fully encapsulates the silicon nitride passivation layer. In one embodiment, silicon dioxide is the barrier material. In another embodiment, spin-on-glass is the barrier material. In still another embodiment, cermet is the barrier material.
Claims15
A method for attaching a first surface to a second surface, said method comprising:
- a) encapsulating a plurality of electrodes in an encapsulant region of said first surface with a barrier material for chemically isolating said plurality of electrodes from a sealing material;
- b) depositing said sealing material between said first surface and said second surface;
- and
- c) subjecting said sealing material to a sealing process in order to attach said first surface to said second surface.
