Abstract:
A plasma display panel is provided with front and rear boards each having a plurality of electrode members, respectively. The front and rear boards are spaced apart to define a discharge space filled with an ionizable gas. The front board is equipped with a front glass plate including a fluorescent or phosphorescent element set on its inside surface, and a central plate having a number of holes therethrough. The electrode members of the front board are affixed by a coating to an inside surface of the central plate. The fluorescent or phosphorescent elements are placed at the rear of the electrode members on the central plate.
Abstract:
The present invention discloses a method for writing information on a plasma display panel with the minimum write voltage. In the plasma display panel, an upper member and a lower member face each other, sandwiching a gap filled with gas therebetween, and the upper member had column electrodes covered with a dielectric layer and the lower member has row electrodes covered with a dielectric layer, and the upper and the lower members are not similar in construction and/or in the material of which they are made. In one embodiment, when a secondary electron radiation emissivity of the surface of the dielectric layer of row electrodes which are provided on the lower member is higher than a secondary electron radiation emissivity of the surface of the dielectric layer of column electrodes which are provided on the upper member, a write voltage is supplied to selected electrodes with a polarity such that the row electrodes become negative and the row electrodes become positive.
Abstract:
A gas discharge panel which has a shift layer for shifting a priming fire with a surface discharge and a display layer for memory and display when a discharge is produced between opposing electrodes. An equivalent electrostatic capacitance provided by a dielectric layer coated on the shift layer is made larger than that by a dielectric layer on the display layer to increase thereby a wall charge on the shift layer resulting from the surface discharge and decrease that resulting from the discharge between the opposing electrodes, thereby eliminating the possibility that an unnecessary priming fire for shifting is generated at the position of the discharge produced between the opposing electrodes.
Abstract:
A plasma lamp includes plates that are approximately parallel, with at least one array of microcavities formed in a surface of at least one plate. When desirable, the plates are separated a fixed distance by spacers with at least one spacer being placed near the plate's edge to form a hermetic seal therewith. A gas makes contact with the microcavity array. Electrodes capable of delivering a time-varying voltage are located on the surface of each plate. At least one electrode is located on an exterior surface of at least one interior plate. Optionally, protective windows may be placed over the electrodes. The application of the time-varying voltage interacts with the gas to form a glow discharge plasma in the microcavities and the fixed volume between the plates (when present). The glow discharge plasma efficiently and uniformly emits UV/VUV radiation over the entire surface of the lamp.
