Problems solved by technology

[0009] However, since the opening width of the discharge space 30 is designed in a fixed ratio, the red discharge space 30R is under the trend of the manufacturing process where the resolution of the plasma display panel is continuously increasing and all the discharge spaces 30 are required to be reduced. The opening width will be designed to be very small
In this way, in the actual manufacturing process, it will not only increase the difficulty of manufacturing the barrier ribs 28 and the red fluorescent layer 32R, but also cause alignment problems when sealing the first substrate 12 and the second substrate 14.
In addition, because the opening width of the red discharge space 30R is too narrow, it is easy for the ionized gas discharged to cross talk to the adjacent discharge space 30 to cause interference, thereby affecting the electrical performance of the color plasma display 10

Embodiment Construction

[0018] refer to figure 2 , figure 2 It is a schematic diagram of the first embodiment of the color plasma display 40 of the present invention. The color plasma display 40 includes a rear panel 42 and a front panel 44 , and the front panel 44 is disposed on the rear panel 42 in parallel. A plurality of first electrodes 46 and second electrodes 48 are disposed on the front plate 44 , a dielectric layer 52 also covers the front plate 44 , and finally, a protective layer 54 covers the dielectric layer 52 . There is a gap between the front plate 44 and the rear plate 42 , so that an ionized gas can be filled between the rear plate 42 and the front plate 44 .

[0019] In addition, a plurality of address electrodes 50 are disposed on the rear plate 42 . Each first electrode 46 and second electrode 48 are arranged on the front plate 44 in a manner parallel to each other, and each address electrode 50 is arranged on the rear plate 42 in a manner perpendicular to the first electrod...

Abstract

The plasma display includes a rear panel, a front panel, and a plurality of barrier walls parallel to the rear panel. Multiple discharge space groups are defined on the rear panel, and each discharge space group has a first and a second discharge space. The first discharge space is composed of the corresponding back plate surface and the barrier wall side wall surface surrounding the first discharge space, with a first phosphor layer on it, and the second discharge space is composed of the corresponding back plate surface and the side wall surface surrounding the second discharge space. The sidewall surface of the barrier wall is formed with a second fluorescent layer on it. The thickness of the second phosphor layer is greater than the thickness of the first phosphor, so that the surface area of ​​the first phosphor layer on the side wall surface of the barrier wall surrounding the first discharge space is greater than the surface area of ​​the second phosphor layer on the surface of the side wall surface of the barrier wall surrounding the second discharge space.

Description

technical field [0001] The invention relates to a plasma display, in particular to a color plasma display capable of adjusting the coverage area of ​​a fluorescent layer to improve color temperature. Background technique [0002] A color plasma display (Plasma Display Panel, PDP) is composed of hundreds of thousands of display units of about hundreds of microns. The principle of light emission is to apply a voltage to discharge an ionized gas to generate ultraviolet rays. When different phosphors are used, each phosphor can emit three primary colors of light: red, green and blue. Generally speaking, the color emitted by the phosphor depends on the fluorescent material used therein. When the fluorescent material is yttrium borate ((Y, Gd)BO 3 ), and adding erbium (Eu) as the luminescent center, red fluorescence will be produced; when the fluorescent material is zinc sulfate (Zn 2 SO 4 ), and adding manganese (Mn) as the luminescent center will produce green fluorescence; ...
