Abstract: An intermediate electrode (18) is formed in a space between an X display electrode (2) and a Y display electrode (3) parallel thereto. Metal barrier ribs (16) held between a front substrate and a back substrate define cells. The intermediate electrode (18) and the metal barrier ribs (16) are grounded and are used as anodes. One of the cells having surfaces coated with fluorescent layers (10), respectively, is selected by driving an address electrode (7) and the Y display electrode (3), and the Y display electrode (3) in the selected cell is charged with a wall charge. A negative voltage is applied to the Y display electrode (3) to use the Y display electrode as a cathode. A charge is stored between the Y display electrode (3) and the intermediate electrode (18) to create an electric field. Upon the increase of the intensity of the electric field to a sufficiently high level, an instant discharge occurs between the Y display electrode (3) and the X display electrode (2) and intense ultraviolet rays are produced. The fluorescent layer (10) excited by the ultraviolet rays emits visible light. Only a narrow pulse current flows through the X display electrode (2) and the Y display electrode (3), so that power consumption can be suppressed at high emission efficiency. Thus, the present invention can realize a reduction in power consumption while maintaining high emission efficiency.

Abstract: An electrode drive circuit performs interlaced scanning, ensuring that the phases of the sustaining pulse in odd-numbered lines and even-numbered lines among L1 to L8 between surface discharge electrodes are the reverse of each other. With this, when either odd-numbered lines or even-numbered lines are displayed, the voltages applied between the electrodes of the undisplayed lines are at 0, eliminating the necessity for partitioning walls on the surface discharge electrodes. In surface discharge electrodes, X electrodes are provided on the two sides of a Y electrode and the area between the Y electrode and the X electrode on one side is assigned a display line at an odd-numbered frame, and the area between the Y electrode and the X electrode on the other side is assigned a display line in an even-numbered frame. Alternate areas between the surface discharge electrodes are assigned as blind lines and a discharge light emission in the blind lines is blocked or incident light to the blind lines from the outside is absorbed. Address electrodes are provided for each monochromatic pixel column and selectively connected with the pads above them, performing simultaneous selection of lines.

Abstract: A method of driving a plasma display panel to improve display brightness and luminescent efficiency. In the sustain periods, the same driving signal is sent to the sustain electrode X as well as the address electrode Ai at the same time to achieve the desired volume discharge effect. In addition, the structure of PDPs is modified to raise firing voltages between these electrodes, preventing erasure of the data written in the address periods.

Abstract: An AC plasma panel display includes front and back panels that respectively support a first parallel electrode pattern and a second orthogonally oriented, parallel electrode pattern. The electrode patterns define a display area and both patterns are covered by dielectric layers. A dischargeable gas is positioned between the dielectric layers in the known manner. Driver circuitry is coupled to both electrode patterns for creating a spatially continuous gas discharge along at least one continuous electrode of one electrode pattern and across the entire display area. The driver circuitry scans the spatially continuous gas discharge across remaining parallel electrodes of the one electrode pattern so as to scan the entire display area. A further electrode is in DC conductive communication with the gas and is positioned outside of the display area but in contact with the spatially continuous gas discharge during its scanning action. The electrode provides a capacitive structure which prevents a build-up of an excessive static charge on the dielectric layers and thereby prevents dielectric breakdown.

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: A gas discharge display panel which provides sufficient contrast and good accuracy and is high in yield. When a voltage is applied to auxiliary discharge electrodes, auxiliary discharge occurs in an auxiliary discharge space and excited charged particles communicate with a main discharge space through a priming path made in a discharge space separation bulkhead. In this state, when an alternating voltage is applied between bus electrodes on a front substrate, main discharge occurs in the main discharge space, causing Xe atoms in the sealed gas to generate ultraviolet rays, causing a phosphor to emit light. However, since the auxiliary discharge is shielded by a bulkhead and a barrier rib, the phosphor does not emit light when only auxiliary discharge occurs.
