  • Patent number: 7336032
    Abstract: An electrode in a plasma display panel and a fabrication process thereof that is capable of reducing a line width of the electrode without increasing a resistance component of the electrode. In the method, a bus electrode is provided by laminating a metal film on a certain substrate and then patterning it. A transparent electrode is provided on the substrate in a shape of surrounding the bus electrode. Accordingly, the electrode is provided by the metal film such that a limit for a selection in a width or thickness of the electrode, so that a line width of the electrode can be reduced to improve the visible light transmissivity and the electrode is formed into a large thickness instead of making a minute electrode width to lower the resistance component, thereby reducing a power consumption of the PDP.

  • Patent number: 6783416
    Abstract: A plasma display panel including a barrier rib for separating a discharge space thereof into a discharge cell unit and a method of fabricating the barrier rib. The barrier rib is formed by utilizing an electro plating technique. Accordingly, it is possible to shield electrical and optical interference between discharge cells and to improve the radiation efficiency. The barrier rib fabricating method is so simple that it can obtain an improvement of the productivity and a reduction of the manufacturing cost.

  • Patent number: 6511793
    Abstract: The present invention relates to a method of manufacturing a microstructure such as a barrier lib or a spacer formed at an internal space between two flat panels constructing a flat panel display and, in particular, to a method of manufacturing a microstructure using a photosensitive glass substrate. The method of manufacturing a microstructure in accordance with the present invention includes the steps of preparing a photosensitive glass substrate, forming a mask pattern having a light transmission unit and a shading unit on the photosensitive glass substrate, exposing the photosensitive glass substrate, heat-treating the photosensitive glass substrate, and etching an unexposed portion of the photosensitive glass substrate. In addition, the process of changing the thermal expansive coefficient of the microstructure by heat-treating the photosensitive substrate again can be additionally included after etching and removing the unexposed portion.
