Abstract: A plasma display device comprises two plates defining a gas filled space therebetween, striped anodes and cathodes, wherein the cathodes are composed of a first cathode element and a second cathode element, and a sealing layer. The second cathode is formed on said first cathode element. The sealing layer is formed between the cathodes to prevent the first element from being exposed to the gas filled space. The device forms a high-quality picture by minimizing the difference in luminance between pixels.

Abstract: A diverging magnetic field is established between the cathode and control electrode of a hollow cathode plasma switch to expand the plasma at a passageway through the control electrode, thus significantly increasing the switch's current handling capability. Preferred ranges of magnetic field strength, gas pressure, spacing between the hollow cathode and control electrode, and the mesh aperture size for the control grid are described.
