Abstract:
The present invention is to provide an AC type PDP which can be manufactured by an inexpensive thick-film process without a thin-film process which is difficult to manufacture an MgO protection layer and the like and which has a panel structure that can be driven at a low voltage. Of a pair of discharge electrodes, one electrode is formed as a so-called AC type electrode in which a conducting electrode material is formed as an independent floating electrode separated at every pixel, this floating electrode being connected through a dielectric layer to a bus electrode in a capacity coupling fashion. The other discharge electrode is formed as a so-called DC type electrode in which a bus electrode is exposed to the discharge space as it is. The above-mentioned two electrodes are paired to form an AC type PDP which carries out discharge display
Abstract:
Almost only choice by a secondary electron emission layer/protection layer covering the dielectric layer of an AC type PDP has been magnesium oxide (MgO) that is unstable during the production process and difficult to form, thus posing a serious production problem. An AC type PDP constructed such that, instead of covering the surface of a dielectric layer (3) with a dielectric material such as MgO, an insular electrode (4) is made by forming a conductive material such as nickel, aluminum, magnesium and lanthanum hexaboride into an insular shape, and the insular electrode (4) is allowed to capacity-couple with a lower-layer bus electrode (9) by means of an electrostatic capacity formed by a dielectric layer (3) to operate the insular electrode (4) as a sustained electrode.

A method of driving an indicator tube comprised of a pair of common memory electrode plates and independent address XY electrode groups separate therefrom comprises the steps of, in a case where an address discharge is to be carried out by the XY electrode groups from a state that no wall charge uniformly exists on wall surfaces of the pair of memory electrodes in all cells on a picture screen or on a line to be addressed, holding one of the pair of memory electrodes 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 of the pair of memory electrodes 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.
