Abstract:
A plasma display panel arranged with a sub-electrode within the interior of a barrier rib for improving the structure which produces the priming particle. The invention is characterized in that the sub-electrode is formed within the interior of the barrier rib so that sputtering of the charged particles generated during the main discharge is reduced. According to the invention, damage to the primary electrodes can be prevented, and the spatial structure of the cell is simplified so that the quality of the visual display is improved.

Abstract:
An AC plasma display panel with a coated thin film dielectric layer on the electrodes has a structure which includes double layers of chromium (Cr) and copper (Cu). After three metal layers of chromium, copper, and chromium are formed on a glass substrate, these three metal layers are subjected to patterning with the desired electrode pattern in such a fashion as to eliminate the upper chromium layer. Then, a thin dielectric film of alumina (Al.sub.2 O.sub.3) is evaporated onto the two remaining metal layers forming the electrodes. This combination of two layer metal electrodes and dielectric layer is very useful in providing a self-shifting plasma display panel having high quality and reliability.

Abstract:
A D.C. gaseous discharge display panel operated in a storage mode uses a layer of resistive material over the cathodes of the display. In addition to protecting the electrodes from ion bombardment induced sputtering during discharge, the material provides a resistance to each discharge cell, provides isolation between individual cathodes by reducing discharge spreading along the cathode conductors and prevents surface charge building during panel operation. By utilizing a combination of metal and insulator in the resistance layer, the D.C. discharge can be sustained at lower operating voltage, permitting a reduction in the power requirements of the panel.

The nickel compound may be incorporated into or on the dielectric by any suitable means, including being applied as a layer within the dielectric or on the surface thereof.
Abstract:
A blue color AC gas discharge display panel is obtained by the room-temperature Hg vapor seeding of high pressure Ar gas as the luminous gas mixture. Typically, the panel uses room-temperature Hg (approximately 3m Torr) in several hundred Torr of argon. Generally, good resolution is achieved in standard AC panels in at least 300 Torr. The upper limit is nominally one atmosphere. This gives an Hg seeding of less than 0.001% of the total gas pressure. Thus, direct electron excitation of Hg atoms is negligible and the discharge condition involves only the excitation of argon atoms by the electrons.
