Problems solved by technology

In addition, the increase of xenon (Xe) content can also increase the discharge instability such as discharge delay time.
[0015] In addition, in the existing PDP, metal electrodes 14B, 16B are formed on the outer edges of the transparent electrodes 14A, 16A, and the distance between the metal electrodes 14B, 16B is relatively long, so the discharge start voltage and discharge sustain voltage will be increased.
Due to the high discharge start voltage and discharge maintenance voltage in the existing PDP, there is a discharge delay time, which may cause unstable discharge, and may also reduce gray scale and efficiency

Embodiment Construction

[0043] Below, refer to Figure 3 to Figure 8b , The embodiment of the plasma display of the present invention will be described.

[0044] Reference image 3 , The plasma display panel (Plasma Display Panel: hereinafter referred to as "PDP") in the first embodiment of the present invention is composed of the following components: a pair of sustain electrodes 114, 116 formed on the upper substrate 110 in sequence; with an upper dielectric The upper plate of the layer 118 and the protective film 120; the address electrode 122 sequentially formed on the lower substrate 112; the lower dielectric layer 124; the lower plate with the partition wall 126 and the phosphor layer 128. The upper substrate 110 and the lower substrate 112 are separated in parallel by the partition wall 126.

[0045] The pair of sustain electrodes 114 and 116 are composed of a scan electrode 114 and a sustain electrode 116. The scan electrode 114 supplies a scan signal suitable for display screen scanning and a sust...

Abstract

Disclosed a plasma display comprises a couple of maintaining electrodes formed on the upper base plate; a upper plate with upper dielectric medium layer and the protective film; a address electrode formed on the lower base plate; a lower dielectric medium layer; a lower plate with dividing wall and fluorophor layer. Wherein, the upper base plate and the lower base plate are parallel separated via the dividing wall, and said couple of maintaining electrodes comprises transparent electrodes each of which is separated and metal electrodes formed on the opposite side of said transparent electrodes. In the process of discharge, the invention can reduce the discharge initial voltage and the discharge maintaining voltage via the stronger electric field of the center of discharge unit. In addition, The invention also can improve the grey scale, the efficiency and the discharge safety.

Description

(1) Technical field [0001] The present invention relates to a plasma display, in particular to a plasma display that can improve gray scale and efficiency, and can also improve discharge stability. (2) Background technology [0002] Recently, various flat panel display devices capable of reducing the weight and volume of a cathode ray tube (Cathode Ray Tube) have been developed. Among such flat panel display devices, there are liquid crystal display devices (Liquid Crystal Display: LCD), field emission displays (Field Emission Display: FED), plasma displays (Plasma Display Panel: hereinafter referred to as "PDP"), and electroluminescence (Electro Luminescence). : EL) display device, etc. [0003] Among them, PDP is a display element that uses the principle of gas discharge, and has the advantage of being easy to manufacture large-scale display screens. The most representative is figure 1 Shown is a three-electrode AC creeping discharge type PDP driven by AC voltage. [0004] fi...
