Abstract

The invention relates to barrier manufacturing materials and processing techniques for barriers in plasma displays, and especially relates to a plasma display barrier repairing slurry and a repairing method thereof. The plasma display barrier repairing slurry and the repairing method thereof are characterized in that: the repairing slurry comprises 70-92% by mass percentage of a glass powder system and 8-30% by mass percentage of an organic system, wherein the components in the glass powder system and the mass percentage of the components are: 60-70% of Bi[2]O[3], 5-20% of AL[2]0[3], 3-10% of ZnO, 2-10% of B[2]O[3] and 1-5% of SiO[2]; the content of each component satisfies one hundred percent; a mass percentage of the components in the organic system are that: 70-94.5% of a solvent, 4-15% of polymers, 1%-15% of plasticizer and 0.5-8% of additive. The plasma display barrier repairing slurry of the invention is low in melting point. Repairing points are strong in adhesive forces. The plasma display barrier repairing slurry will not easily fall off. The repairing method is simple to operate and the repairing rate is high. Manufacturing of plasma barriers is carried out through utilizing the repairing slurry and the repairing method of the invention, traditional plasma display barrier repairing slurry and repairing methods are replaced. Plasma displays and plasma televisions with a simpler process, a higher processing efficiency, and a better mass production performance and a lower cost are manufactured.

Description

technical field [0001] The invention relates to a barrier rib manufacturing material and processing technology in a plasma display, in particular to a barrier rib repair slurry and a repair method thereof. [0002] Background technique [0003] Plasma display is a flat-panel display device that uses gas discharge to emit light autonomously. It has the advantages of vivid color, wide viewing angle, long life, fast response and no harmful radiation. Plasma display technology is one of the mainstream flat panel display technologies at present. [0004] Plasma consists of a large number of plasma discharge cells arranged. Each discharge cell is composed of a bus electrode, a dielectric protection layer, a barrier structure, phosphor powder, and an inert gas. When high voltage is applied to the bus electrode covered under the dielectric protection layer, the inert gas sealed in the barrier structure discharges to generate ultraviolet light, thereby exciting the red, green and ...
