Abstract
An electron emitter plate (110) for an FED image display has an extraction (gate) electrode (122) spaced by an insulating layer (25) from a cathode electrode including a conductive mesh (118). Circular arrays (112) of microtips (14) are located concentrically within circular mesh spacings (116) on a resistive layer (15), within apertures (26) formed in extraction electrode (122). Microtips (14) are laterally spaced from mesh structure (118) by substantially identical paths of a ballast-providing resistive layer (15), placing all microtips (14) at generally the same potential.
