Abstract: PROBLEM TO BE SOLVED: To lower the cost of an auxiliary positive electrode drive circuit by installing a push-pull circuit which drives the common line, and an auxiliary positive electrode drive circuit and a positive electrode drive circuit which output driver voltage based on the voltage of the common line. SOLUTION: The common line COM driven by a push-pull circuit 3 which is composed from a high side P-FET Fp and the low side N-FET FN is connected to a power recovery circuit 4. In addition, it is connected with an auxiliary positive electrode drive circuit 5 and a positive electrode circuit 6 which output the driving voltage using this common line COM. The auxiliary positive electrode drive circuit 5 is constituted from a step-up transformer Tr alone, and the N-FET FN does not necessitate a level shifter because its source side is at the ground potential. And since the common line COM is connected with a power recovery circuit, none of the resistor group and the diode group are unnecessary in the positive drive circuit 6.

CONSTITUTION:A luminescent panel has a plurality of through-holes 12a for exposing part of each filament 8 in an insulating plate 11 covering a plurality of filaments 8 arranged on a back base board 7, and each through-hole 12a forms one unit of a picture element region together with fluorescent material layers 13a-13c formed in the adjacency of the through-holes 12a. The fluorescent material layers 13a-13c of each picture element region are housed in a cavity 15a of a separating wall 14 formed on the insulating plate 11 and separated from an adjacent fluorescent material layer. The cavity 15a forms a discharge space by using a translucent front plate 16 installed on the separating wall 14 as a cover, each discharge space communicates with the through-hole 12a at its one end in the lengthy direction and faces an anode 17 formed on the lower surface of the front plate 16 at its other end.

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.
