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 with a dielectric material such as MgO, an insular electrode is made by forming a conductive material such as nickel, aluminum, magnesium and lanthanum hexaboride into an insular shape, and the insular electrode is allowed to capacity-couple with a lower-layer bus electrode by means of an electrostatic capacity formed by a dielectric layer to operate the insular electrode as a sustained electrode.

Abstract: According to the present invention, in a plasma display discharge tube in which a plurality of stripe-like anode electrodes (11) and a plurality of stripe-like cathode electrodes (9) are arranged at a predetermined interval to be crossed each other, to thereby constitute an X-Y matrix electrode with a space at each of the crossing portions thereof as a pixel and a plurality of pixels are selectively excited according to an image to display an image, there is provided a plasma display discharge tube in which there are provided an AC type memory electrode (1) arranged opposite to the X-Y matrix electrode (9) and (11) common to all the pixels, and an AC type auxiliary electrode (5) in contact with the AC type memory electrode (1) through an insulating layer and supplying an electric power through a coupling capacitor formed between the same and the AC type memory electrode (1), wherein a memory discharge display is performed between the X-Y matrix electrode (9) and (11) and the AC type memory electrode (1).

Abstract: A discharge display apparatus includes a plurality of first address electrodes (1) and a plurality of second address electrodes (2) both of which are disposed adjacent to each other so as to cross each other through a partition (6) and memory electrodes (3, 4) which have a plurality of apertures provided therethrough and are entirely covered with respective insulating layers (3a, 4a). The plurality of first and second address electrodes (1, 2) and the memory electrode (3, 4) are successively laminated and sealed into a tube body having discharge gas.

Abstract: 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 ima

Abstract: The present invention is directed to a discharge tube for use with a display device which is simple in structure and which can be mass-produced satisfactorily. Further, the discharge tube for display device of the present invention can be increased in resolution and can be made large in size with ease. Furthermore, the discharge tube for use with a display device of the present invention can be made inexpensive with ease. A pair of memory elements (Ma), (Mb) having memory electrodes (3a), (3b) formed of conductive layers having a plurality of apertures (5a), (5b) arranged in an XY matrix form and in which the whole surface of the memory electrodes (3a), (3b) are covered with insulating layers (4a), (4b) are laminated such that corresponding apertures (5a), (5b) covered with the insulating layers (4a), (4b) are communicated with each other to thereby form discharge cells. all of which are sealed into a tube body in which a discharging gas is sealed.
