  • Publication number: 20090033222
    Abstract: In a plasma display apparatus of the preset invention, an external light shielding sheet configured to shield externally incident light to the greatest extent possible is disposed at the front, thus effectively implementing a black image and improving the bright and dark room contrast. Furthermore, pattern units of the external light shielding sheet are formed using a conductivity material. Accordingly, there is an advantage in that EMI emitted from a panel can be prevented from being radiated to the outside.

  • Patent number: 7423378
    Abstract: A plasma display panel is disclosed, which prevents luminance from being reduced, prevents error discharge from occurring due to crosstalk, and improves exhaust ability. Auxiliary barriers or projections are formed in a boundary portion between respective cells in a stripe type barrier structure. Alternatively, a predetermined groove is formed in a predetermined position of a dielectric layer in a lattice shaped barrier structure. In addition to these barriers, second barriers are formed at a greater width or at constant intervals. Thus, exhaust ability can be improved, and error discharge due to crosstalk can be prevented from occurring. Also, luminance in corner portions of the cell can be improved, and contrast can be improved even if a black matrix is not formed.
