Abstract: A rectangular field emission display has a front member with a glass anode support, and a first sidewall section; the display also has a cathode substrate containing an embedded cathode; the display has a rear member with a planar section and a sidewall section; and the display has an evacuated space. The front member and the rear member enclose at least a portion of the cathode substrate. The evacuated space separates the entire anode support section and the cathode substrate.

Abstract: A field emission display having a focusing grid disposed between the anode and a plurality of cathodes. The focusing grid comprises a conductive sheet having an array of apertures formed therein. Each one of the cathodes comprises a set of field emitters. Each aperture is associated with a corresponding set of field emitters. The conductive sheet is disposed over the corresponding set of field emitters. The sheet is supported at the periphery thereof by a frame with the interior portion of the sheet suspended in tension by the frame thereby supporting the grid substantially equidistant over the sets of field emitters. A method is provided for supporting the sheet in tension by the frame includes the steps of providing a clamp having a pair of apertured members. A first member has a groove disposed about the periphery of such member. A ring member is provided.
