Abstract
A flat-panel field emission display comprises a luminescent faceplate, a rigid backplate, and an interposed or sandwiched emitter or cathode plate. A positioning spacer or connector ridge is formed on the rear surface of the faceplate to space the cathode plate a fixed distance behind the faceplate. A peripheral seal is formed between the faceplate and the backplate. The faceplate, backplate, and peripheral seal define an evacuated internal space which contains the cathode plate. The backplate is spaced behind the cathode plate to create a rearward vacuum space in which a getter is located.
