ABSTRACT:
A flat panel display has a faceplate structure, a backplate structure, a focusing structure, and a plurality of spacers. The backplate structure includes an electron emitting structure which faces the faceplate structure. The focusing structure has a first surface coupled to the electron emitting structure, and a second surface which extends away from the electron emitting structure. The electrical end of the combination of the focusing structure and the electron emitting structure is located at an imaginary plane located intermediate the first and second surfaces of the focusing structure. A spacers is located between the focusing structure and the light emitting structure. The spacer is typically located within a corresponding groove in the focusing structure such that the electrical end of the spacer is coincident with the electrical end of the combination of the focusing structure and the electron emitting structure. In other embodiments, the electrical end of the spacer is located above the electrical end of the combination of the focusing structure and the electron emitting structure. In these embodiments, a face electrode on the spacer compensates for the resulting voltage distribution.
