  • Patent number: 7116047
    Abstract: In an Alternating Current (AC) plasma display panel, a rear substrate and a front substrate are arranged to face each other. Discharge cells are formed between the rear and front substrates. A plurality of strip-shaped address electrodes are arranged on the rear substrate. A first dielectric layer is arranged on the rear substrate, and the address electrodes are buried in the first dielectric layer. A plurality of strip-shaped sustaining electrodes are arranged in pairs on the rear substrate to cross the address electrodes at right angles. A second dielectric layer is arranged on the rear substrate, and the sustaining electrodes are buried in the second dielectric layer. A protective layer is arranged on a bottom surface of the second dielectric layer. A plurality of barrier ribs are arranged between the front and rear substrates and define the discharge cells. The lateral sides of each of the barrier ribs are coated with a fluorescent layer.

  • Patent number: 6885151
    Abstract: A flat lamp with horizontal facing electrodes is provided, in which a front substrate and a rear substrate are spaced such as to face each other. Walls between the front and rear substrates form a discharging space filled with a discharge gas. A plurality of front electrodes and a plurality of rear electrodes are provided on facing surfaces of the front and rear substrates, respectively. The front and rear electrodes, formed in strips, are arranged in such a way that the front electrodes alternate with the rear electrodes. Accordingly, the discharging distance between front and rear electrodes is lengthened, and many fine discharging operations occur between tip electrodes extending from the lateral sides of the electrode strips and flat portions of corresponding electrode strips. Therefore, a current concentration is prevented, thereby achieving uniform discharging. Also, brightness of the flat lamp increases.
