ABSTRACT:
Improved plasma displays utilize permanent magnet components for low-voltage operation. Permanent magnet components providing magnetic fields transverse to the direction of electron movement increase the electron pathlength, thereby enhancing the ionization efficiency of the electrons. This permits lower voltage operation, higher-pixel density and greater durability. In exemplary embodiments, magnetic components can be placed below the cathode, disposed between the electrodes, or incorporated in the cathode.
