The panel is provided with a first board having a plurality of display electrodes (6) and a second board having a plurality of address electrodes (10) which intersect with the display electrodes at least via a discharge space and barrier ribs (11) which are arranged between the address electrodes and have protruding parts formed between the display electrodes.
Abstract:
The present invention provides an AC plasma display device using metal nanostructures, including: a front panel and a rear panel which are disposed in parallel to each other and at least one of which is provided with electrodes for gas discharge; an electrode layer, a front dielectric layer and a protective film which are sequentially formed on a side of the front panel which faces the rear panel; a phosphor layer which is formed on the rear panel and which is excited and simultaneously radiated by gas discharge occurring in the electrodes; and metal nanostructures included in the protective film and the phosphor layer, and provides a method of manufacturing the same. The AC plasma display device can improve a secondary electron emission coefficient and photoluminescent intensity using surface plasmon excitation because it is provided with a protective film including metal nanostructures.

Abstract:
The invention concerns a colour plasma panel of the matrix type comprising a first faceplate or front faceplate bearing a first array of electrodes (Y'1, Y'2) and a second faceplate or rear faceplate bearing a second array of electrodes, the first and second faceplates being assembled to produce a matrix of cells defined at the intersection between an electrode of the first array and an electrode of the second array, each cell comprising a discharge zone with resist (Ep1, Ep2, ) on the colour side. The invention is characterised in that each electrode of the first array consists of at least one element (Y'1, Y'2) covering the associated discharge zones, the element being produced in a conductive transparent material and connected to a metal bus (B, B').
Abstract:
A highly reliable plane display panel which has a large operating margin for making displaying operations and can stably display high-quality pictures, a method for manufacturing the panel, a controller for controlling the panel, and a method for driving the panel. The plane display panel is composed of a front glass substrate (1) provided with common electrodes and individual electrodes (3, 3a and 3b) which can be driven individually at every display cell, and a back glass substrate (10) having recessed sections which become discharging spaces. At the time of driving the plane display panel, the polarity of the wall charges accumulated on a dielectric layer (5) during displaying operations is inverted by applying voltage pulses to the individual electrodes (3) separately from the displaying operations. Thereafter, the electric field of the wall charges having the inverted polarity is added to the driving voltage, so that discharge can surely take place by applying voltage pulses for display to the electrodes (3).

The plasma display panel (PDP) includes a front substrate and a second dielectric layer. At least one of the front substrate and the second dielectric layer is formed of a glass material. The glass material includes a transition metal oxide and a rare earth metal oxide. The transition metal oxide is at least one of oxides of cobalt (Co), nickel (Ni), selenium (Se), iron (Fe), manganese (Mn), chromium (Cr), vanadium (V) and scandium (Sc). The rare earth metal oxide is at least one of oxides of praseodymium (Pr), neodymium (Nd), samarium (Sm), dysprosium (Dy) and holmium (Ho).
Abstract:
A technology effective for improving the luminous efficiency, lifetime, and color temperature of a PDP having phosphor layers of three colors is disclosed. A PDP comprises a plurality of narrow tubes (60) arrayed on a substrate (51). In each narrow tube (60), one of phosphor layers (61R, 61B, 61G) is formed and a discharge gas is contained. The compositions and pressures of the discharge gases are set within appropriate ranges respectively corresponding to the phosphor layers (61R, 61B, 61G). Consequently, the PDP can have a lengthened life-time and an improved luminous efficiency. Reductions of variation in breakdown voltage and adjustment of color temperature are also possible with this constitution.
