Abstract: A panel comprises a porous metal plate which has a plurality of holes used for display cells and made correspondingly to the positions where a first linear electrode group and a second linear electrode group intersect at given intervals, and a front glass plate. The diameters on the display side of the holes of the porous metal plate is larger than those of the back side, and the openings on the back side of the holes are closed with a molten inorganic dielectric substance to seal them hermetically; hence a thin, light and easily-assembled plasma display panel is provided.

Abstract: An indicator tube includes a pair of common memory plate electrodes (3, 4) and independent address XY electrode groups (1, 2) separate therefrom. When an address discharge is to be carried out by the XY electrode groups (1, 2) from a state in which no wall charge uniformly exists on wall surfaces of the pair of memory electrodes (3, 4) in all cells on a picture screen or on a line to be addressed, the driving method includes holding one of the pair of memory electrodes (3, 4) at a potential higher than a discharge space potential generated by an address discharge in a range such that a discharge is not caused on the low voltage side of the address electrode during an address period, holding the other memory electrode (3, 4) at a potential lower than the discharge space potential in a range such that a discharge is not caused on the high voltage side of the address electrode, selectively accumulating charged particles generated by the address discharge in cells disposed at the positions corresponding to an image as negative and positive wall charges, and continuously effecting a display discharge or memory discharge utilizing a presence or absence of the wall charges as position information. A variation of this driving method is used when an address discharge is to be carried out by the XY electrode groups (1, 2) from a state in which positive and negative wall charges uniformly exist on wall surfaces of the pair of memory electrodes (3, 4) in all cells on a picture screen or on a line to be addressed.

Abstract: A plasma display panel (PDP) comprises a plurality of anodes (1, 12, 21) on an upper plate, a plurality of first sustaining electrodes (3, 14, 25) and a plurality of alternating second sustaining electrodes (4, 17, 24) and cathodes (2, 16, 23) on a lower plate, and a dielectric (15) on the first and second sustaining electrodes (3, 14, 25 and 4, 17, 24) and cathodes (2, 16, 23). A method for driving the PDP includes the steps of initiating a discharge by supplying a potential higher than the discharge firing voltage to the anodes (1, 12, 21) and cathodes (2, 16, 23), generating a predetermined potential between cathodes (2, 16, 23) and first sustaining electrodes (3, 14, 25) to increase the voltage generated from the discharge-initiating step, supplying a voltage higher than a discharge sustaining voltage between the first and second sustaining electrodes (3, 14, 25 and 4, 17, 24) to maintain the discharge, and supplying a narrow pulse to cathodes (2, 16, 23) for erasing the discharge.

Abstract: A gas discharge panel provides one or more shift channels for discharge spots, said shift channel (s) being composed of 2 or more electrode groups on each of a pair of substrates arranged oppositely across a discharge gap. Electrodes of each group are provided alternately and periodically on each substrate with the electrode patterns on each substrate such as to define said shift channel(s). The electrode layout eliminates the need for crossover areas in the leading out of electrodes and is very useful for realizing high resolution and low cost AC driven self-shift plasma display panels.
