Tae Deok Seo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8125147
    Abstract: In a plasma display apparatus of the preset invention, a filter including 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, since the external light shielding sheet and an EMI shielding sheet are formed to be aligned, thereby sustaining the luminance of the screen.
    Type: Grant

  • Patent number: 8044589
    Abstract: A plasma display apparatus may include an external light shielding sheet attached to a front of a panel to absorb and shield externally incident light. Accordingly, a black image can be implemented close to an original color and bright and dark room contrast can be improved. Furthermore, thickness of the external light shielding sheet and height of a pattern unit have a given ratio in order to properly secure an aperture ratio of the external light shielding sheet. Accordingly, light emitted into the panel can transmit toward a user side.

  • Patent number: 7764016
    Abstract: A plasma display apparatus may include a plasma display panel (PDP), and a filter disposed at a front of the PDP. The filter may include an external light shielding sheet having a base unit and a plurality of pattern units formed on the base unit. Each of the pattern units may include a bottom and first and second slanted surfaces which are connected to the bottom. A thickness of the external light shielding sheet may be in a range of 1.01 to 1.5 times greater than a height of each of the pattern units and a first interior angle between the first slanted surface and the bottom of each of the pattern units may differ from a second interior angle between the second slanted surface and the bottom of each of the pattern units.

  • 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.
