Title:
DISCHARGE TUBE FOR DISPLAY AND METHOD FOR DRIVING THE SAME
Document Type and Number:
WIPO Patent Application WO/2000/005740
Kind Code:
A1
Abstract:
A discharge tube for display provided with an electrode group containing electrode pairs for display and first address electrodes on one of the facing surfaces of two opposing substrates and another electrode group containing second address electrodes on the other facing surface. The two electrode groups are arranged so that the electrodes of one group may intersect those of the other group and discharge areas enclosing a gas are provided at the intersections. The discharge areas are partitioned by partition walls arranged between the two substrates. The electrode pairs for display are covered with a dielectric layer and arranged nearly in parallel to each other. At least one of the first and second address electrodes are also covered with the dielectric layer. Each first address electrode is extended between each electrode of the electrode pairs for display and each partition wall is extended between each second address electrode. When the discharge tube is constituted in the above-mentioned way, the luminous efficiency and luminance of the tube are improved, because the electrode pairs for display and the address electrodes are independent of each other and the electrode pairs for display can be arranged at long intervals.
