  • Patent number: 7081706
    Abstract: A plasma display panel with a plurality of non-transparent display electrode pairs and a method of forming the same. Each electrode of every non-transparent display electrode pair is separated from but close to one another for effective discharging. For effective displaying, it is necessary that the area of the non-transparent display electrodes is smaller than the area of the panel. In the present invention, the shape of the non-transparent display electrodes are manufactured in a shape with a plurality of openings, such as a ladder or a chain.

  • Patent number: 6960497
    Abstract: The present invention provides a method for improving the adhesion capability between the ?-type bus electrode and ITO (indium tin oxide) transparent conductive layer. The method includes an ITO transparent conductive layer as an ITO electrode is formed on the glass substrate by sputtering method. Then, a photoresist layer with a cavity pattern is formed on the portion of the ITO transparent conductive film. Next, an etching process is used to remove portion of the ITO transparent conductive film to form a cavity within the ITO transparent conductive film. Then, after removing the photoresist layer, a silver paste as a bus electrode is formed on the glass substrate and on the ITO transparent conductor film to form a pi (?) type bus electrode by print method.

  • Patent number: 6900591
    Abstract: A driving electrode structure of a plasma display panel for improving operation margin is described. A plurality openings is formed in a transparent electrode according to the driving characteristics of fluorescent layer of each luminous cell to adjust the effective area of the transparent electrode in each luminous cell, thereby increasing the operation margin of the sustaining voltage.

  • Patent number: 6881117
    Abstract: A bus electrode of the present invention is formed by first coating a Ru-containing layer on the front plate and the transparent electrodes. Then, an Ag-containing layer is coated over the Ru-containing layer. In accordance with the present invention, the coating area of the Ru-containing layer is larger than the coating area of the Ag-containing layer to improve adhesion between the bus electrodes, glass plate and the transparent electrodes. Then, a photolithography process is performed to define the bus electrodes.

  • Patent number: 6838826
    Abstract: A discharge electrode structure of a plasma display panel is described. The discharge electrode structure includes a plurality of expanding electrodes or expanding portions that each one has a symmetric structure. The expanding electrodes are alternately coupled to a pair of conductive electrodes that are on the edge of a plurality of luminant cells in one row. Therefore, oblique symmetric electrodes are disposed at opposite corner location of each luminant cell.

  • Publication number: 20040183440
    Abstract: The pla sma display panel has some pairs of non-transparent discharge electrodes. Herein, no transparent discharge electrode is desired. Herein, for each pair, the non-transparent discharge electrodes are separated but closed to effectively discharge. Besides, the area of the non-transparent discharge electrodes is clearly smaller than the area of the panel. Furthermore, the shape of each non-transparent discharge electrode is alike to a shape with some openings, such as ladder or chain.
