ABSTRACT:
An apparatus is provided for reducing color bleed in a flat panel display. The apparatus comprises an anode (30) with a plurality of phosphors (28) of at least two colors sequentially disposed thereon. A cathode (14) is arranged in parallel opposed position to and separated from the anode (30) and contains a plurality of pads (40) of emitters. Each pad (40) is disposed on the cathode (14) in spaced relationship to and aligned with one of the at least two colors, respectively, wherein electrons from each of the plurality of pads of emitters that drift from its intended phosphor (28) are encouraged to drift toward an adjacent phosphor (28) of the same color.
