Today's known flat panel displays include liquid crystal displays, plasma displays, field emission flat displays, ..., and many other products. The imaging technology and structure applied to each product are also different. The "Plasma Display Panel (PDP)" in the mouth is a large-scale digital display with a large viewing angle and a thin and light profile. The conventionally known plasma display panel is shown in the fifth figure, which is mainly formed by the front panel (30) and the rear panel (40) being aligned and sealed. The front panel (30) is mainly Scan electrodes (32) and sustain electrodes (Sustain 200540904) are arranged on the side of a glass substrate (31) of a predetermined size in parallel at a plurality of intervals.

The rear panel (40) is mainly formed on another glass substrate (41) to form straight address electrodes (Address Electrc) (42) arranged in parallel and spaced apart. Barrier ribs (44) are formed opposite to each side of each addressing electrode (42), and red, green, and blue (j ^ b) of a predetermined area are screen-printed within the interval of the barrier wall (44). Three primary colors. The front and rear panels (30) and (40) are sealed in position, and an inert gas such as neon or xenon is passed into the gas channel while sealing, and the address electrode (42) is perpendicular to the front. The scan electrodes (32) and the sustain electrodes (33) of the panel (30), so that each pair of the scan electrodes (32) and the sustain electrodes (33) and the address electrodes (34) intersect at an intersection corresponding to having a primary color of fluorescent light The discharge interval of the body forms a discharge area, and three adjacent red, green, and blue light-emitting discharge areas form a pixel, thereby enabling the gas in the electro-polymer display panel to be controlled when a voltage is applied to it. After the plasma effect is generated, ultraviolet light is emitted to excite the red, green, and blue primary color phosphors in the straight barrier (44) to emit visible light of red, green, and blue. Full color image effect with different color levels. It can be seen from the basic composition of the front plasma display that the plasma display uses an external electric μ 'to make the intermediary between the front and rear panels: the inert gas inside the panel to produce a line destruction effect to emit The material is used to excite 1 200540904 The red, green, and blue three-color phosphors on the side walls of the barrier ribs and the surface of the rear panel emit visible light of red, green, and blue. Therefore, is the inert gas sealed between the front and rear panels doped with other Unexpected gas will affect the development quality of the plasma display panel. However, in the aforementioned plasma display panel structure, because the barrier wall of the rear panel adopts a straight structure design, the coverage area of the coatable three-primary phosphors is small, which makes its luminous efficacy low, and the In the process, the ionized gas crosses easily into the adjacent discharge space, which affects its electrical performance. Therefore, in order to overcome the shortcomings of the front and rear panel barriers, some people have proposed, for example, China's Announcement No. 4805522 "a color electric display panel" and Announcement No. 492929 "AC discharge type" Invention patents such as the barrier wall structure of each discharge cell in the plasma flat display ", or for example, US No. 6,411,043" AC TYPE PLASMA DISPLAY PANEL HAVING IMPROVED PARTITIONS ", US 6,495,967" DISCHARGE CELLS BETWEEN BARRIER WALLS OF ALTERNATING " "CURRENT DISCHARGE TYPE PLASMA DISPLAY PANEL" (Same as previously disclosed in China Announcement Patent No. 4929329), and US 6,525,469 "FULL-COLOR PLASMA DISPLAY PANEL WITH RIBS EXTENDING ALONG TWO DIRECTIONS" (Same as previously disclosed Disclosed in China's Announced Patent Case No. 480522) and other patent cases. It can be known from the contents disclosed in the above-mentioned patent cases that it uses a plurality of corresponding sets of bumps on the straight bar of each adjacent two barrier walls to make the space between the adjacent two sets of bumps. Is a discharge area; or, staggered bumps are arranged on two adjacent barrier ribs of 200540904, so as to use the extended bumps to provide the area covered by the two primary color phosphors, and improve their luminous efficacy. The blocking of the bumps reduces the problem of interference caused by the ionized gas crossing the side discharge space during the plasma discharge. However, the technical solutions disclosed in various patent cases can indeed achieve the intended purpose and effect. However, because the barrier wall is formed with a large number of bumps, its shape and structure are very complicated, which makes the barrier wall Increasing difficulty and poor uniformity of the phosphor layer also increase the time required to seal and exhaust the front and rear panels, which reduces product yield and mass production speed. On the other hand, due to the research and development trend of plasma displays, in addition to the large size of the Buza plus its resolution to improve the clarity and detail of the South screen is also one of the focus of research and development. It will complicate the shape and structure of the display panel. Once the resolution of the display panel is increased, the distance between the bumps and the bumps will be relatively reduced. Therefore, it will increase the difficulty of forming and manufacturing the barrier wall. Further review and improvement. [Summary of the Invention] The main purpose of the present invention is to provide a barrier wall for the rear panel of a plasma display, which is designed to use the barrier wall within the allowable range of the predetermined luminous efficacy and electrical interference of the plasma display. The simplification of the shape and structure is expected to reduce the difficulty of the barrier wall forming and manufacturing, and improve the product yield and mass production speed. In order to achieve the purpose of the disclosure, the technical solution proposed by the present invention is to make the barrier wall formed on a panel glass-based 200540904 plate with a plurality of parallel arrayed address electrodes, arranged in parallel at a parallel interval between each adjacent two address electrodes. Strips, each side of the strip at each of its predetermined positions extends laterally symmetrical bumps, the two adjacent straight strips are staggered and correspond to the black of different positions of the front panel Strip, so that the distance between the bumps of two adjacent bars includes more than one (inclusive) cell interval composed of a pair of scan electrodes and sustain electrodes. Compared with the design of the barrier wall disclosed in the previous patents, the present invention utilizes the design of the front-opening technical scheme, which can simplify the predetermined luminous efficiency and allowable range of electrical interference of the plasma display panel product. The structural design of the barrier wall shape reduces the technical difficulty of the barrier wall forming and manufacturing, and improves the product yield and the speed of mass production, which improves the utilization value of industrial manufacturing and use. [Embodiment] As shown in the first and second figures, it is a three-dimensional exploded view showing the rear surface of the barrier wall of the present invention and its front panel. As can be clearly seen from the figure, the child panel (10) is mainly composed of A glass substrate (1i) is formed with scan electrodes (⑵, sustain electrodes (13) arranged in parallel and spaced apart), and black bars (ι4) arranged in parallel on each side of each pair of scan electrodes (12) and sustain electrodes (13) ), Between. The adjacent black bars (14) define the correspondence _ pair of scan electrodes (i 2) and the cell spacing of the maintenance electricity = (13) ⑻, its detailed structure is the same as the front panel of the conventional plasma display The rear panel (20) is mainly formed on a glass substrate (21) with a plurality of linear address electrodes (22) arranged in parallel and spaced in parallel, and the address electrodes (22) are perpendicular to The scanning electrode (12), the sustaining electrode (〗 3) and the 200540904 black bar (14) on the front panel (10) are covered with a dielectric layer (23). Please refer to Figures 1 and 2 for details. The barrier wall (24) of the invention mainly has a plurality of parallel rows arranged between each adjacent two address electrodes (23). The straight bars (241) in the row, the symmetrical straight bumps (242) extending laterally from the mother straight bar (2 41) at each of its predetermined positions, and the bumps of two adjacent straight bars (241) (242) the black bars (14) in a staggered arrangement and corresponding to different positions of the front panel (10), so that the distance between the protrusions (242) of two adjacent straight bars (241) includes one or more than one The cell distance (D) is composed of a pair of scan electrodes (12) and sustain electrodes (13). As shown in the first and second embodiments, it is disclosed that two barrier walls (24) of the present invention are adjacent to each other. The stripe (241) and the bumps (242) are staggered and correspond to the black stripe (14), and the adjacent bump (2 4 2) includes a pair of scan electrodes (12) and a sustain electrode (13). ) Constituted by the element spacing (j)); as shown in the third embodiment, it is revealed that the barrier ribs (24) of the present invention are arranged adjacently to each other and correspond to the black stripes. (14), and the two adjacent bumps (242) include more than two cell distances (D) composed of a pair of scan electrodes (12) and sustain electrodes (13); as shown in the fourth figure Of an embodiment, It is revealed that the pitch of the front and rear bumps (241) of a barrier wall (24) of the present invention includes more than three cell spacings (D). The arrangement of the bumps (242) of the straight bars (241) corresponds to the black bars (14). In addition, three adjacent barrier ribs (24) are a group, and the first bumps (242) of each barrier rib (j4) are sequentially separated by more than one cell pitch (D) in the vertical direction. After the barrier wall (24) of the present invention is formed on the rear panel (20) glass substrate (21), the patterned three 200540904 primary color phosphors can be filled into the barrier wall (24) by screen printing, and the barrier can be blocked by The two side walls of the wall (24), the straight bar (241), the bumps (242), and the surface of the dielectric layer (23) of the rear plate (20) provide the area covered by the phosphor. After that, the front and rear panels (1〇 ) (2 ()) is sealed in position, and an inert gas is passed in when sealing. The rear panel (20) addressing electrode (22) is perpendicular to the front scanning electrode (12) and the sustaining electrode (12) 13), so that each pair of the scanning electrode (12) and the sustaining electrode (13) intersects with the addressing electrode (22) and forms a discharge region corresponding to a discharge region with-one kind of primary color phosphor, every three Adjacent red, green, and blue light-emitting discharge areas constitute a pixel (pixel) '— a plasma display panel. The design of the previously disclosed technical solution of the present invention is obviously more simplified in shape and structure than the barrier walls disclosed in the previously disclosed patents. Perhaps, the present invention's streamlined design with its shape and structure may not be as effective as the previously disclosed patents in terms of phosphor coverage and reduction of electrical interference. However, the present invention further utilizes the sparse projections on the barrier wall. The block distribution design can still be used in the plasma display panel, providing better luminous efficiency and reducing electrical interference than traditional = straight bars, so the plasma display panel products can tolerate the lighting efficiency and electrical interference. In terms of scope, the present invention simplifies the shape and structure of the barrier wall. Compared with the complicated barrier wall structures disclosed in the previous patents, it can indeed reduce the difficulty of forming and manufacturing the barrier wall, and improve the product yield and mass production speed. . In summary, the present invention, with its innovative technical solution, can indeed provide a rear wall with a simpler shape barrier wall within the scope of the electro-polymer display panel product that meets the predetermined allowable standards for luminous efficacy and electrical interference. Design and achieve specific contributions to reducing industrial barrier manufacturing difficulties and improving product yields 200540904 and speed of mass production. Therefore, the present invention meets the requirements for invention patents, and is filed in accordance with the law.
