Embodiment Construction

[0013] Hereinafter, a plasma display device according to an embodiment of the present invention will be described with reference to the drawings.

[0014] (Embodiment) figure 1 It is a perspective view which shows the structure of the panel 10 in embodiment of this invention. In the panel 10, the front panel 20 and the rear panel 30 are arranged to face each other, and the outer peripheral portion thereof is sealed with a sealing material of low-melting glass. In the discharge space 15 inside the panel 10, a discharge gas such as xenon is sealed with a pressure of 400 Torr to 600 Torr.

[0015] A plurality of display electrode pairs 24 including scan electrodes 22 and sustain electrodes 23 are arranged in parallel on glass substrate (first glass substrate) 21 of front panel 20 . A dielectric layer 25 is formed on the glass substrate 21 so as to cover the display electrode pairs 24 , and a protective layer 26 mainly composed of magnesium oxide is formed on the dielectric laye...

Abstract

Disclosed is a plasma display device characterized by comprising: a protective layer (26) for a front plate (20) in a plasma display panel, the protective layer (26) comprising a substrate protective layer (26a) formed of a thin film of a metal oxide comprising at least one of magnesium oxide, strontium oxide, calcium oxide, and barium oxide, and a particulate layer (26b) formed by adhering single crystal particles (27) of magnesium oxide having an NaCl crystal structure, surrounded by specific two types of oriented planes of (100) plane and (111) plane or by specific three types of oriented planes of (100) plane, (110) plane and (111) plane, to the substrate protective layer (26a); and a panel drive circuit configured so that the panel is driven by temporally arranging subfields in such a manner that the weight of brightness from the subfield where an entire cell initialization operation is performed, to the subfield just before the subfield where the next entire cell initialization operation is performed is monotonically decreased. The above constitution can lower a writing pulse voltage.

Description

technical field [0001] The present invention relates to a plasma display device as an image display device using a plasma display panel. Background technique [0002] Plasma display panels (hereinafter simply referred to as "panels") are realized as large-screen display devices because they can perform high-speed display even in thin image display elements and can be easily increased in size. [0003] The panel is constructed by gluing the front and back panels together. The front panel includes a glass substrate, display electrode pairs including scan electrodes and sustain electrodes formed on the glass substrate, a dielectric layer formed so as to cover the display electrode pairs, and a protective layer formed on the dielectric layer. The protective layer is provided for the purpose of protecting the dielectric layer from ion collision and easily generating discharge. [0004] The rear panel includes a glass substrate, data electrodes formed on the glass substrate, a d...
