    Abstract: PROBLEM TO BE SOLVED: To facilitate writing discharge, maintaining discharge, and erase discharge, to eliminate the generation of faulty writing and erase failure, and to improve the quality of display by setting an overall discharge operation period before a train of displaying operation periods and by conducting image display while repeating this series of periods. SOLUTION: A group of scanning electrodes, 3-1 to 3-n, a group of maintaining electrodes, 4-1 to 4-n, and a group of data electrodes, 10-1, to 10-n, are respectively connected to a scanning electrode driving circuit 16, a maintaining electrode driving circuit 17, and a data electrode driving circuit 18 to be driven. An overall discharge operation period is set before each train of displaying operation periods composed from at least one displaying operation period to conduct picture image display using this combination as one unit. Thus, irrespective of image display, writing discharges and maintaining discharges are generated in all discharge cells during the overall discharge operation period to regularly supply wall charge and space charge to all discharge cells. As a result, writing discharge, maintaining discharge and erase discharge become liable to occur.

    Abstract: PURPOSE:To provide a gas discharge type display device simplifying a panel structure further with low power consumption and long life. CONSTITUTION:A group of striped address electrodes 2, dielectric layer 3 and a group of striped cathodes 4 are successively piled to be provided on a glass substrate 1, and a group of striped anodes 6 and an insulating layer 7 are successively piled to be provided on an insulating substrate 5. Relating to a group of the address electrodes 2, a group of the anodes 6 is arranged to be opposed orthogonal through the dielectric layer 3 and insulating layer 5. A discharge hole 10 is provided in the insulating layer 7 in an orthogonal opposed part to groups of the address electrodes 2 and anodes 6 so as to expose at least partly a group o,f the anodes 6, and a group of the cathodes 4 is arranged to be opposed orthogonal relating to a group of the address electrodes 2 so as to accumulate an electric charge in a surface of the dielectric layer 3 in at least the periphery of a group of the cathodes 4.

    Abstract: PURPOSE:To simplify the panel structure of a display apparatus, lessen the electric power consumption, and extend the life by forming discharge holes in a second dielectric layer and setting address electrodes and anodes face to face as to accumulate electric charge on the surface of the second dielectric layer existing at least in the periphery of the discharge holes. CONSTITUTION:To display the same images in a matrix-type panel, positive potential is applied to anodes 4 corresponding to the discharge cells 9 in the first row in which the images are to be displayed and negative potential applied to address electrodes 2 in the first row. As a result, writing discharge occurs and positive charge is accumulated on the surface of a second dielectric layer 5 and writing discharge automatically stops and at the same time the display content of the first row is saved in the surface. In this case, discharge holes 10 are so formed as to expose at least a part of anode group 4 to the layer 5 and the electrodes 2 and the anodes 4 are set face to face as to accumulate the charge on the surface of the layer 5 existing at least in the peripheries of the holes 10. As a result, charge is accumulated on the layer 5 and writing discharge stops automatically and discharge current can be controlled, so that the panel structure can be simplified and electric power consumption can be lowered and a long operational life can be provided.
