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.
Claims22
A plasma display apparatus, comprising:
- a Plasma Display Panel (PDP);
- a transparent substrate spaced apart from and adhered to the PDP;
- a base unit formed on the transparent substrate;
- pattern units formed within the base unit, wherein a black oxidization process is performed on the pattern units;
- an Anti-Reflection (AR) layer formed on the transparent substrate to a thickness of 90 to 120 μm;
- and
- a Near Infrared (NIR) shielding sheet formed on the transparent substrate to a thickness of 100 to 120 μm,
- wherein a width at ½ of a height of each of the pattern units is set in the range of 6 to 23 μm, a bottom width of the pattern unit is set in the range of 18 to 35 μm, and the pattern units are formed using a material containing carbon.
