Problems solved by technology

But for example, the fluorescent ink coated on the top 6 of the auxiliary partition wall 2a crosses the partition walls 1a, 1b and overflows, and flows into the adjacent discharge spaces that emit light of different colors, causing the so-called color mixing problem.
Even if the next door is set in a snake-like rear panel, this problem may also occur in the narrow part of the next door. If such a color mixing problem is caused, the PDP will not be able to display full color.

[0035] A first embodiment of the fluorescent ink application apparatus of the present invention will be described below with reference to the accompanying drawings.

[0036] [Structure of PDP]

[0037] First, the structure of the PDP 100 produced by applying fluorescent ink by a fluorescent ink application device will be described.

[0038] figure 1 is a schematic plan view of the PDP 100 with the front glass substrate removed, figure 2 It is a partially cutaway perspective view showing the image display area 123 of the PDP 100 . In addition, in figure 1In the figure, the number of display electrodes 103, display scan electrodes 104, address electrodes 107, etc. are partially omitted for easy understanding. Referring to these two figures, the structure of PDP 100 will be described.

[0039] like figure 1 As shown, the PDP 100 consists of a front glass substrate 101 (not shown in the figure), a rear glass substrate 102, N display electrodes 103, and N display scanning...

[0127] Next, a second embodiment of the fluorescent ink application apparatus according to the present invention will be described. Please note that the fluorescent ink application device in this second embodiment, except Figure 5 outside the nozzle member 750 of the marked first embodiment, with Figure 4 , Figure 5 Basically the same as shown. Therefore, the different parts will be explained below as a center.

[0128] Figure 8 It is an exploded perspective view showing the structure of the nozzle member 750 of the fluorescent ink ejection device of the second embodiment.

[0129] As shown, the nozzle member 780 includes a cap portion 781 and a spout portion 782 which are positioned in alignment with each other and hermetically secured together. The cover part 781 is made of a flat stainless steel material, and its central part is provided with an inlet 783 for introducing fluorescent ink into the ejection part 782 .

[0130] The ejection part 782 includes: an ink s...

Abstract

The object of the present invention is to provide a phosphor ink applying device that can apply phosphor ink in a plurality of lines to an intricately-shaped surface of a back panel of a PDP while preventing phosphor colors mixing. A valve is provided for the aperture of each nozzle of the phosphor ink applying device and the opening and closing of each valve is controlled according to the shape of the portion of the surface to which ink is to be applied. In this way, mixing of colors can be prevented on an intricately-shaped back panel such as that with auxiliary barrier ribs.

Description

field of invention [0001] The present invention relates to a color display panel for image display such as televisions and computers and a manufacturing method thereof, in particular to a plasma display panel having a fluorescent film and a manufacturing method thereof, and a fluorescent ink coating for coating the fluorescent film thereof device. technical background [0002] In recent years, in terms of color display devices for displaying images such as computers and televisions, so-called plasma display panels (hereinafter referred to as PDPs) have attracted attention as color display devices capable of being large, thin and lightweight. [0003] The PDP performs full-color display by adding and mixing the three primary colors (red, green, and blue). In order to perform this full-color display, the PDP has a strip-shaped partition between the front panel and the rear panel, and at the same time, there are fluorescent lights emitting red (R), green (G), and blue (B) betw...
