Description of the Invention: [Technical Field] The present invention provides a flat type double-sided display, and more particularly to a double-sided plasma display. [Prior Art] In recent years, flat-panel displays have developed rapidly. They have been widely used in personal computers, mobile communications, and consumer electronics, and have become one of the most popular information technology technologies. Currently, flat-panel displays that are commonly used include plasma display (PDP), liquid crystal display (LCD), and field emission display (FED). Among them, plasma display people have the advantages of wider viewing angle, higher brightness, lower energy consumption, longer service life, better light efficiency and shell size, and wider operating temperature than other flat-type displays. Made into a fully flat and ultra-thin large screen (40 inches or more). Please refer to the first figure, which is a structural diagram of a conventional plasma display. The plasma display 1 includes a transparent substrate 11 and an opaque insulating substrate 12. A transparent insulating layer 15 is formed on the bottom surface of the transparent substrate 11, and display electrodes 13 and scanning electrodes 14 which are parallel to each other are interposed in the transparent insulating layer 15, and a protective layer 16 is formed on the bottom surface of the transparent insulating layer 15. An insulating layer 18 is formed on the surface of the transparent substrate η against the opaque insulating substrate 12, and the address electrodes 17 which are parallel to each other are interposed in the insulating layer 18, and the address electrodes are formed on the surface of the insulating layer Η The barrier rib 19 of the phase is coated with a phosphor layer 1 内 on the inner surface of the groove formed by the insulating layer 18 and the barrier rib 19 . Further, the discharge space 168 formed by the protective layer 16 and the insulating layer 18 is filled with an inert gas. When the electric power applied between the display electrode 13 and the scanning electrode 14 is greater than the starting voltage thereof, the electric field effect between the display electrode 13 and the scanning electrode 14 causes the inert gas in the discharge space 168 to generate ultraviolet light ^ red, green The blue primary color glory layers 101, 102, and 103, which == the layer excites visible light, and the light emitted by the transparent substrate n can be seen. Most of the research on the plasma display industry in the industry focuses on the electrode structure, the voltage driving method, the discharging method, and the manufacturing or improvement method, and the like, and an improved method of the scanning electrode, for example, in US Pat. No. 6,703,772. In order to obtain a better display effect, the Japanese Patent No. 1143554.2 of the Ten Kingdoms relates to a plasma display with a low start-up. These electric=displays are displayed on the front side and the back side is not displayed. In order to adapt to the electro-convergence display = large screen Application requirements, such as traffic lights, information on various large-scale occasions ''', staff board and circular electric brothel, etc., need to display the purpose of two faces, the traditional side is to use two single-sided display panels placed The opposite direction is to be able to be viewed before and after. This setting will result in the display without the back of the display being used insufficiently, wasting the usable space; two sets of drive systems are required: the cost is too thin; and the wiring is complicated. The reliability of the display is not good, which is conducive to the actual promotion and application. ' In summary, provide a full use of display space, simple structure The invention relates to a low-cost double-sided plasma display. [Invention] In order to solve the shortcomings of the prior art plasma display, such as single-sided display, low space utilization, complicated structure and high cost, the present invention provides two-six six The February 2nd revised page utilizes a double-sided plasma display having a display space, a simple structure, and a low cost. To achieve the above object, the present invention provides a double-sided plasma display comprising two mutually parallel display screens; The discharge structure between the display screens has the same structure, and includes a transparent substrate and a transparent scanning electrode, a transparent display electrode, a transparent insulating layer and a protective layer formed on opposite surfaces thereof, the discharge structure separating the internal space of the display In two parts, comprising an opaque insulating substrate, the insulating substrate has two front and back surfaces facing the two display screens respectively, and the two sides of the insulating substrate are symmetrically formed with a plurality of parallel addressing electrodes, and an address addressing An opaque insulating substrate of the electrode, a plurality of barrier layers, and a plurality of phosphor layers. The poles are formed on the same surface and are spaced apart from each other at a distance from each other inside the transparent substrate; the barrier is located on the surface of the opaque insulating layer facing the display screen, supported between the protective layer and the opaque insulating layer, The address electrodes are spaced apart from each other in parallel. The phosphor layer is formed on the inner surface of the recess formed by the opaque insulating layer and the barrier rib. The space between the opaque insulating layer and the transparent substrate is filled with air, air, gas, and argon. Gas and other inert gas or a mixture thereof. Each of the address electrodes is opposite to a corresponding phosphor layer. When the scan electrode and the display electrode are row electrodes, the address electrodes are column electrodes 'the scan electrodes and the display electrodes In the case of a column electrode, the address_ is a row electrode. A further improvement of the present invention is that each pair of the same row electrode symmetrical with respect to the insulating substrate in the double-sided plasma display is electrically connected to each other, and each pair is related to the center of the insulating substrate. The axisymmetric column electrodes are electrically connected to each other, so that a single driving system is used less, and the same image is displayed on both sides. -February __日 Revision page The non-discharge edge between the two protective layers formed on the transparent substrate is formed with sidewalls of the branches which are perpendicular to each other and spaced apart from each other by a certain gap. Compared with the prior art, the double-sided plasma display of the invention adopts a symmetrical electrode double display structure, can realize double-sided display, has a simple structure and can fully utilize the double-sided miscellaneous of the age screen. The double-sided pro-display of the present invention further realizes the same image on both sides of the display by reducing the connection of the (four) electrodes; at the same time, the line-side complexity is reduced by the shared-sleeve drive system, and the cost of a set of drive systems is saved. [Embodiment] The present invention will be further described in detail below with reference to the accompanying drawings. Please refer to the second figure, which is a schematic diagram of a pixel of a display unit of the plasma display of the present invention, that is, including three primary colors (10).

The discharge layer 258 formed by the protective layer 25 and the opaque insulating layer 38 and the discharge space 258 formed by the opaque layer 25 and the opaque layer 38 ′ are filled with a discharge gas, which is selected from the group consisting of helium gas, Helium, neon, argon and other miscellaneous gases or mixtures thereof. In addition, a sidewall 41 supporting them is formed on the edge between the ship layer 25 and the protective layer 25'. The sidewall 41 is perpendicular to and spaced apart from the opaque, s-edge substrate 31, so that the two discharge chambers 258 The gap between the side wall 41 and the front and rear two screens .20, 20 forms a peripheral structure of the display. Here, the opaque insulating substrate 31 functions as a smooth light, and the refractory layers of the front and back glory layers 4, 40 can be eliminated from the (four) into two discharge regions which do not interfere with each other. Another 12 1286337~~ February 1996 Correction Page The outer side wall 41 is located in the non-discharge edge area and will not adversely affect the discharge and display effects. When the voltage applied between the display electrode 23 and the scan electrode 24 is greater than the startup voltage, the electric field effect between the display electrode 23 and the scan electrode 24 causes the inert gas in the discharge space 258 to generate electrons to form a space charge, and utilizes the search. The electric field between the address electrode 37 and the scanning electrode 24 acts to generate a plasma. When the charge is made into a filament, the material can be ignited, and then the ultraviolet light is emitted. The red, green and blue primary colors of the light county are fluorescent, 402 403 The two primary color fluorescent layers excite visible light, and the light emitted by the transparent substrate 1 P can be seen. If the charge density is insufficient to ignite the plasma, it becomes unbright. Similarly, under the same action, the inert gas in the discharge space 258 will generate ultraviolet light, and the primary color will be layered, moved, and moved to the top of the substrate to see the light emitted by the substrate. As a result, the image can be seen on both display screens 2, 20, and through the display electrodes 23, 23, the sweep 2^, 24' and the address electrodes 37, 37, between the drive system, wash, that is, It can achieve the effect of displaying images on both sides. Please refer to the fourth and fifth figures, sub-point =: electricity: connection diagram with the column electrode, only the electrode connection of the slip condition is the same, which is described in detail here. First, the same row of the cleaning condition is taken as an example to connect the detailed + address electrodes, that is, the address electrodes 37i and the address electrodes 371 of the first row respectively on the opposite surfaces of the 13 曰 correction page transparent insulating layer 38. Connected through the line 42 to connect the address electrodes of the second row on the opposite surfaces of the opaque insulating substrate 31, microphase, and then sequentially connect the other rows on both surfaces of the opaque insulating substrate 31 in the same manner. (as shown in the fourth figure). For the column electrodes, it is customary to follow the order from left to right when viewing the image. Therefore, the connection of the column electrodes should be located on the protective layers 25, 25, and the symmetrical column electrodes are connected to the insulating substrate. Since the display electrodes are strong at this time, and the 23 electrodes 24 and 24 are all connected in the same manner, the electrodes 23 and 23' are taken as an example. Symmetrical according to the center of the column electrode = the first column on the protective layer 25 shows that the electrode 231 passes through the line _, light ==5; the first column shows the electrode (four) mesh connection, and the other columns, the same, the electrode is not pressed Connect in the same way (such as the first column = according to the connection method can achieve double-sided display related: like it, in addition, in order to make different images on both sides, you can use the same Realize the different images on both sides of the pros and cons.
