Problems solved by technology

[0009] Although the closed discharge tank 220 with a honeycomb outline is different from the closed discharge tank 120 with a rectangular outline, all of its barrier walls 230 also have the same wall height H2, so the sealed panel It also has the property of being in a vacuum state that is not easy to pump
[0010] Therefore, the disadvantages of the above-mentioned traditional plasma display with closed discharge tanks are: all the barrier walls blocking the closed discharge tanks have the same height of the barrier walls, which makes it difficult for the sealed panel to be effectively pumped, resulting in the need to A very long pumping time to achieve a vacuum in the panel

Embodiment Construction

[0032] Also refer to Figure 3A and Figure 3B . Figure 3A To show a schematic diagram of a closed discharge tank with a rectangular outline in a plasma display according to a preferred embodiment of the present invention, Figure 3B for display corresponding to Figure 3A Perspective view of the region indicated by the dotted line in the center. The manufacture of the plasma display 300 is carried out in conjunction with a sintering process. The plasma display 300 mainly includes a glass substrate 310 and a plurality of closed discharge tanks 320 with roughly rectangular outlines.

[0033] The closed discharge tanks 320 are located on the glass substrate 310 . As shown in the figure, each closed discharge tank 320 is surrounded by four barrier walls 330 . Before the sintering process, at least one of the four barrier walls has varying wall thicknesses T31 and T32.

[0034] For the same barrier wall 330 , the non-uniform wall thicknesses T31 and T32 can make the barrier...

Abstract

Procedure of manufacturing plasma display is assorted with agglomeration technology. The plasma display includes glass base plate and multiple close typed discharging grooves. Multiple enclosed obstructing walls form discharging grooves on glass base plate. There is at least one obstructing wall with variable wall thickness in these obstructing walls. After agglutinating, obstructing walls with variable wall height, which are obstructing walls with variable wall thickness before agglutinating.

Description

technical field [0001] The present invention relates to a plasma display (plasma display panel, PDP) and its manufacturing method, and in particular to a plasma display with a closed discharge tank (cell) and its manufacturing method. Background technique [0002] Generally speaking, the process of plasma display can be divided into upper substrate process, lower substrate process, sealing process, heating / pumping / encapsulating inert gas process and assembly process. [0003] The upper substrate process includes placing two electrodes (discharge electrode and bus electrode), a dielectric layer and a protective film in each discharge slot. The lower substrate process includes electrode fabrication, reflective dielectric layer fabrication, barrier rib fabrication, and phosphor coating. In addition to separating the discharge tank, the barrier wall also has the function of supporting the upper and lower substrates. After the upper and lower substrate processes are completed, ...
