Abstract
A barrier rib structure of plasma display panel is disclosed. The barrier rib structure includes a plurality of vertical barrier ribs arranged in parallel, a plurality of first horizontal barrier ribs connected to one side of the vertical barrier ribs, and a plurality of second horizontal barrier ribs connected to the other side of the vertical barrier ribs, in which the first horizontal barrier ribs are disposed alternately with corresponding second horizontal barrier ribs for forming a plurality of double blockade structures. Additionally, a gas passage and a plurality of electrical discharge spaces are formed between the double blockade structures.
Claims11
A barrier rib structure of plasma display panel (PDP) comprising:
- a plurality of parallel arranged vertical barrier ribs, wherein a first distance is generated between any two vertical barrier ribs adjacent to each other;
- a plurality of parallel arranged first horizontal barrier ribs having a first length, wherein the first horizontal barrier ribs are connected to one side of the vertical barrier ribs;
- a plurality of parallel arranged second horizontal barrier ribs having a second length, wherein the second horizontal barrier ribs are connected to the other side of the vertical barrier ribs, and disposed alternately with the corresponding first horizontal barrier ribs for forming a plurality of double blockade structures, wherein the gap between each first horizontal barrier rib and each second horizontal barrier rib of the double blockade structure comprises a gas passage, and the height of each first horizontal barrier rib and each second horizontal barrier rib gradually decreases from the end connected to the vertical barrier ribs to another end for forming the gas passage;
- and
- a plurality of electrical discharge spaces formed between the double blockade structures and the vertical barrier ribs, wherein each of the electrical discharge-spaces are formed between two adjacent gas passages.
A method of fabricating the barrier rib structure of a plasma display, the method comprising:
- providing a substrate;
- providing a paste over the surface of the substrate for forming a barrier rib pattern, wherein the barrier rib pattern comprises a plurality of parallel arranged vertical barrier ribs, a plurality of parallel arranged first horizontal barrier ribs connected to one side of the vertical barrier ribs and a plurality of parallel arranged second horizontal barrier ribs connected to the other side of the vertical barrier ribs, wherein the first horizontal barrier ribs and the corresponding second horizontal barrier ribs are disposed alternately for forming a plurality of double blockade structures, wherein each of the double blockade structures comprise a gas passage and an electrical discharge space is formed between two gas passages, and the height of each first horizontal barrier rib and each second horizontal barrier rib gradually decreases from the end connected to the vertical barrier ribs to another end for forming the gas passage;
- and performing a firing process for firing the barrier rib patterns.
