Problems solved by technology

However, this method has limitations in changing the thickness of the front or back dielectric layer or the spacing between the two
In addition, with the recent trend of reducing the size and thickness of PDPs, the modification effect of this structure becomes worse

Abstract

A Plasma Display Panel (PDP) having a structure capable of preventing a permanent afterimage generated by damage to a protective film during a sustain discharge includes: front and rear substrates arranged to face each other; barrier ribs arranged between the front and rear substrates to partition discharge cells in combination with the front and rear substrates; a plurality of electrodes adapted to generate a discharge in the discharge cells; a plurality of X electrodes each including a transparent X electrode arranged at a rear side of the front substrate in the discharge cell to extend in one direction; a plurality of Y electrodes each including a transparent Y electrode arranged at a rear side of the front substrate in the discharge cell to be spaced apart from the X electrode by a gap and to extend to and be aligned with the transparent X electrode; opaque X and Y shield layers respectively arranged on one end surface of the transparent X and Y electrodes, the one end surfaces neighboring the gap; a first dielectric layer arranged to cover a rear surface of the front substrate, the X and Y electrodes, and the opaque X and Y shield layers; a protective layer arranged to coat a rear surface of the first dielectric layer; a phosphor layer arranged in each discharge cell; and a discharge gas filling in an inner space of each discharge cell.

Description

technical field [0001] The present invention relates to a plasma display panel (PDP), and more particularly, to a PDP in which electrodes are respectively formed on facing substrates and a discharge gas is injected between the facing substrates In the discharge space between the electrodes, ultraviolet (UV) rays are radiated in the discharge space by the voltage supplied to the electrodes, and the light emitted by the UV rays generates an image. Background technique [0002] PDPs may be broadly classified into direct current (DC) PDPs and alternating current (AC) PDPs according to discharge types. In a DC PDP, corresponding electrodes are exposed to a discharge space, and the discharge is generated by direct motion of charged particles between the corresponding electrodes. In an AC PDP, at least one electrode is covered with a dielectric layer, and the discharge is generated by an electric field induced by wall charges rather than by direct motion of...
