Abstract: A plurality of scanning electrodes and a plurality of sustaining electrodes parallel to each other are located on an inner face of a first glass substrate. Each of the scanning electrodes and each of the sustaining electrodes form a pair. A dielectric layer and a protection layer are formed on the first glass substrate in this order, covering the electrodes. A plurality of data electrodes perpendicular to the scanning electrodes and the sustaining electrodes are located on an inner face of a second glass substrate which is located opposed to the first glass substrate with a discharge space interposed therebetween. In an AC-type PDP having such a structure, at least one of the plurality of scanning electrodes and the plurality of sustaining electrodes are divided into a plurality of groups, and pulses having different phases are applied to the electrodes in different groups, thereby causing sustaining discharge. The scanning electrodes and the sustaining electrodes may be comb-like with teeth. The comb-like scanning electrodes and the comb-like sustaining electrodes are opposed to each other with a small gap interposed therebetween in the manner that the teeth thereof are in engagement with each other. In such a case, the data electrodes are located opposed to and in a longitudinal direction of the teeth of the scanning electrodes.

Abstract: PROBLEM TO BE SOLVED: To correctly execute the multilevel display without generating flicker noise by dividing a subfield in the order of higher luminance among plural subfields, each constituting one field, into plural parts. SOLUTION: In the arrangement of plural subfields in multilevel a display driving method, one field period (1/60sec) of a TV display system and the subfield Sub 8 having the highest luminace are timewisely divided into, for example, nine pieces of subfields, Sub5, Sub6, Sub8a, Sub8b, Sub1,..., Sub4. Moreover, the multilevel displays of 2 (=256) are performed every 1/60sec by selectively performing light emitting displays of the nine subfields, Sub5, Sub6, Sub8a, Sub8b, Sub1,..., Sub4 in this order. The subfield Sub8 having the highest luminance is divided into two parts, Sub8a, Sub8b and they are arranged by being separated with each other in such a manner.

Abstract: PURPOSE:To control discharge current as well as to reduce the electric power consumption of a driving device and to allow POG (package on glass) while eliminating the need for an anode resistor of a high resistance value for limiting the discharge current by providing a constant current output circuit which compares the output of a logical circuit for display with a reference power source output. CONSTITUTION:The constant current output circuit 19 and the anode resistor 20 are connected to the electric lines from the logical circuit 9 for display to the respective anodes 4a, 4b... of a discharge tube for display. The constant current output circuit 19 has the function to form the constant current by as much as to control the discharge current. The anode resistor 20 is merely used for protecting the constant current output circuit 19 and is, therefore, required to be much smaller than the conventional anode resistor. The electric power consumption by the anode resistor is drastically reduced in this way and the direct packaging of integrated circuit elements for driving, etc., on a flat glass plate is possible. The POG is thus possible.

Abstract: PURPOSE:To lower the peak value of discharge current by dividing at least either one of a scanning electrode and a maintaining discharge electrode into plural groups in a maintaining discharge period and providing a phase difference between pulse voltages to be applied. CONSTITUTION:A positive polarity charge image is stored on the surface of a protection film layer, and many scanning electrodes are divided into four scanning electrode groups in the maintaining discharge period succeeding to the write period, and negative pulse voltages Vs shown by SCN(A)-SCN(D) are applied to respective scanning electrode groups. In this case, the phase difference is provided so that the rise time of the negative pulse voltage Vs of the SCN(A), the rise time of the negative pulse voltage Vs of the SCN(B), the rise time of the negative pulse voltage Vs of the SCN(C) and the rise time of the negative pulse voltage Vs of the SCN(D) are delayed successively. Further, in an erasure period, a negative narrow width erasure pulse voltage Ve is applied to all maintaining discharge electrodes.

Abstract: PURPOSE:To ensure extinguishing action of an AC type PDP form display device. CONSTITUTION:A plurality pairs of electrode groups, such as a pair of a discharge holding electrode 2a and a scanning electrode 1a arranged in parallel thereto, are arranged on the inside face of the first glass substrate and a protection film layer is provided on a dielectric layer for covering these electrode groups. A plurality pairs of electrodes such as a pair of an address electrode 7a, which is opposed to the protection film layer via discharge space and three- dimensionally crosses with the above electrode groups, and an extinguishing electrode 9a arranged in parallel thereto, are arranged on the inside face of the second glass substrate.

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.
