摘要： PROBLEM TO BE SOLVED: To adapt the gas volume, which is released or absorbed by a storing material for the partial pressure control of the dopant gas in the channel, to actual operational and environmental conditions of the display device. SOLUTION: The plasma address display device comprises a channel substrate 2 equipped with a long channel chamber 30, a covering sheet 4 which seals each chamber at the upper side of the channel chamber and forms the sealed channel chamber, electrodes 3a, 3c for selective ionization of the gas inside the channel, a source having a storing material 53 for reversibly absorbing and releasing a dopant, gas that is mixed with major ionizing gas in the sealed channel chamber, and a heater 5H for heating the storing material. The device also comprises a feed-back loop for controlling the partial pressure of the dopant gas in the sealed channel chamber. This loop comprises a measuring means 10A for measuring the damping time of the conductivity in at least one of the channel chambers from the off-operation of the plasma in the channel chamber and a control means 10B for controlling the temperature of the storing material by the heater, based on the measured value so that the damping time is contained within the prescribed range.

摘要： PROBLEM TO BE SOLVED: To provide the strengthening of the adhesion property of barriers, the lower resistance of electrodes and remedy for disconnection by improving the electrode structure of a plasma address display device. SOLUTION: The plasma address display device has a flat panel structure formed by superposing a display cell 1 on an a plasma cell 2. The plasma cell 2 has discharge channels 12 successively arrayed along a scanning direction. The display cell 1 is joined to the plasma cell 2 and has signal electrodes 5 successively arrayed in a direction orthogonal with the scanning direction and liquid crystals 7 connected thereto. The plasma cell 2 has a lower substrate 8 joined to the display cell 1 side via a prescribed spacing, discharge electrodes 9 formed on the substrate 8 along the respective discharge channels 12 and the barriers 10 formed on the substrate 8 so as to partition the respective discharge channels 12 to each other. The discharge electrodes 9A are composed of a pair of longitudinal line parts 9AT which are disposed on both sides of the barrier 10 and are parallel with each other and plural transverse line parts 9AS which are disposed in the bottoms of the barriers 10 and connect a pair of the longitudinal line parts 9AT to each other. A ladder type structure is thus formed as a whole.

摘要： PROBLEM TO BE SOLVED: To facilitate scattering of a getter material so as to continuously eliminate impurity gas generated from internal constituents by arranging a getter, which is arranged in the circumference part of an image effective part for absorbing impurity gas, and a shut off film preventing the getter material from scattering on the image effective part side in a vacuum space. SOLUTION: A front board 101 and a back board 102 are overlapped each other, while residual gas inside is evacuated when vacuumizing. When voltage is gradually applied to an electrode 105, heat is generated from the electrode 105 so as to be transmitted to a sheet getter 104. When temperature of the sheet getter 104 reaches a certain temperature, the sheet getter 104 is dispersed. On an image effective part (a) side, a blocking film 106 is arranged, so that most of the scattered sheet getter material 104 is scattered between the shut off film 106 and a frit seal 103 so as to be applied to the front base board 101, the back base board 102, and the frit seal 103 between the shut off film 106 and the frit seal 103. The scattered sheet getter 104 absorbs impurity gas moving to the image effective part (a) side so as to prevent voltage increase between discharge electrodes, and consequently, deterioration of a screen can be prevented and its life can be prolonged.

SOLUTION: The respective electrodes 24, 26 in the channel of a channel member 4 include adhesive layers and bulk layers (conductive cores). The adhesive layers and the bulk layers are conductive and are uniform in the compsn. along the longitudinal direction of the electrodes. Further, the respective electrodes have the protective coatings of the materials which are electrically conductive and do not react with the hydrogen. Further, a coating 54 of a heat resistant material is formed on the cathode 26. The heat resistant material is preferably rare earth hexaboride, such as LaB6 .

摘要： PROBLEM TO BE SOLVED: To dispense with the removing of an oxidized layer for preventing the conductivity reduction of an anode due to oxidation to be generated in a baking treatment by providing an apex part layer of an oxidation resistant material on the anode. SOLUTION: An anode 24 and a cathode 26 are respectively provided with a deposition layer 46 and a bulk layer 48. These layers 46, 48 are conductive and characteristics (strucurtral states) of them are uniform over longitudinal directions of respective electrodes. Moreover, a heat resistant layer (coating of heat resistant material) 54 is provided on the cathode 26. Then, the anode 24 has a protective apex part layer 50. The apex part layer (upper surface) 50 being on the bulk layer 48 is conductive and is produced with material having a strong resistance with respect to oxidation. Further, the characteristic (structural state) of the protective apex part layer 50 is uniform over the longitudinal direction of the electrode. There are gold, silver, platinum, rhodium and iridium or the like as material suitable for such a protective apex part layer 50.

摘要： PROBLEM TO BE SOLVED: To make it possible to prolong an effective life even if display quality is maintained by replenishment of a dopant gas and sputtering damage is ameliorated by forming the surface layer of an anode of a uniform compsn. and having high electric conductivity. SOLUTION: The channel structural body has a channel member having channels 20, a cathode 26 having the exposed surface within one piece of the channel and the anode 24. The surface of one piece of the anode 24 consists of nearly the uniform compsn. and the electric conductivity perpendicular to its surface is at least about 10 Ω cm . The anode 24 and the cathode 26 have adhesive layers 46, bulk ayers 48 and protective top part layers 50. These layers are conductive and have the compsn. uniform over the longitudinal direction of these electrodes. The anode 24 is not connected to the negative terminal of an electrophoresis adhesion voltage source but a slight amt. of LaB6 adheres to the anode 24 and the oxidation thereof is conceivable. Then, a heat resistant coating is formed on the cathode and, thereafter, the electrodes are subjected to a sputtering treatment to remove the LaB6 or the oxide on the anode.

摘要： PROBLEM TO BE SOLVED: To stably maintain electric discharge state of each cell, reduce data quantity which a driving circuit shares, and enable designing by ordinary elements by independently driving a split screen. SOLUTION: In the case of four-piece splitting, for example, a common electrode 103 of a transverse electrode and a scanning electrode 102 parallel thereto are split horizontally by a bulkhead 116, and a data electrode 101 of a vertical electrode is vertically split at a substantial center part. That is, the transverse electrode and an insulation film formed on a surface thereof are horizontally split into two sections by the bulkhead 116 and are vertically split into two sections similarly, and a total of four divisions are achieved. Thereby, in comparison with when a single driving circuit is driven, a period of maintenance pluses increases, and necessary time at the maintenance pulse period to be constantly discharged is reduced. Since there is much pixels on a large-sized screen, expensive high-speed elements such as gallium arsenide is necessary, however, regular flip-flop can be used by screen division, and a serial-parallel converting circuit can be achieved.
