Abstract:
Provided is a plasma display panel. The plasma display panel comprises: a front substrate; a rear substrate opposing the front substrate; a plurality of discharge electrodes disposed inside the substrates; a plurality of light emitting layers formed inside discharge cells; and an electron emitting source disposed inside the discharge cells so as to supply electrons, the area of electron emitting source differing in each of the discharge cells. The electron emitting source is installed in the discharge cells such that an electron emission characteristic is improved and brightness and luminous efficiency of the plasma display panel can be improved. The area of the electron emitting source or the number of electron emitting sources in each of the discharge cells differs such that a discharge characteristic in the discharge cells having lower brightness can be improved.

Abstract:
A design for a plasma display panel (PDP). The novel PDP has two separate layers of fluorescent material. One layer of fluorescent material can generate long wavelength from VUV rays and the other fluorescent layer can convert either of VUV or long wavelength ultraviolet rays into visible rays. Such a PDP improves the luminance efficiency by more efficiently using the UV and VUV rays generated during plasma discharge.
