A6 B6 鱷濟部中央揉準局β：工消費合作社印* 五、發明説明（1 ) 本發明是有關類似單色或彩色映像管等陰極射線管之 發明，而更明確地說則是有關一種陰極射線管，其中有一 磷光R螢赛鍍於面板之内表面，並有許多區域以相互獨立 之方式被掃瞄著的發明。 最近已有許多高品質廣播以及設計給高品質廣播使用 的大螢幕高解析度映像管方面的研究。一般言之，為了達 到映像管之高解析度要求，電子束打在磷光質螢幕之光點 直徑必須加以縮小。為達此目的，在先行技術中，電子搶 之電極結構已被改良過了，或者電子搶之口徑以及/或者 長度的均已增加。然而，滿意之作法卻仍未達成。丰要原 因是：電子槍和磷光質螢幕之間的距離，因為映像管尺寸 之增加以及電子透鏡之放大率的增加而大量增加。因此， 為達高解析度之要求，縮短電子搶和磷光質螢幕之間的距 離（深度）將非常重要。此外，當電子束的折射角增加時 ,在磷光質螢幕之中央區域和邊緣區域之間的放大率差將 增加。因此，大~角度折射對高解析度之達成没有好處。 在此情形下，於先行技術中有一已知的方法來安排許 多獨立的小尺寸映像管，因而可建立一健高解析度、大螢 幕之産品。此類方法對有大置分割區域的大尺寸螢幕顯示 極為有效，這是設計給戶外設立顯示幕之用的。然而當此 方法應用到中尺寸螢幕顯示之用時（例如：螢幕尺寸約 40吋時），在螢幕之分割區域之間的連接部份將極為顯 著，造成低品質之畫面。因此，當由此法所裂成之顯示器 用於家庭用電視接收器或電腦輔助設計（CAD)時，螢 (請先閲讀背面之注意事項再塡寫本頁) 丨裝. 訂· -線. 本纸張尺度適用中西國家標準（CNS)甲4規格（210X297公釐）.3 - 81.9.25,000 A6 B6A6 B6 Central Bureau of Crocodile Economy β: Printed by the Industrial and Consumer Cooperatives * V. Description of the invention (1) This invention relates to the invention of cathode ray tubes such as monochrome or color picture tubes, and more specifically to A cathode ray tube, in which a phosphorescent R fluorescent match is plated on the inner surface of the panel, and there are many inventions in which areas are scanned independently of each other. Recently, there have been many studies on high-quality broadcasting and large-screen high-resolution picture tubes designed for high-quality broadcasting. Generally speaking, in order to meet the high resolution requirements of the picture tube, the diameter of the spot where the electron beam hits the phosphor screen must be reduced. To achieve this goal, in the prior art, the electrode structure of the electronic grab has been improved, or the diameter and / or length of the electronic grab has been increased. However, the satisfactory approach has not yet been reached. The main reason is that the distance between the electron gun and the phosphor screen is greatly increased due to the increase in the size of the picture tube and the magnification of the electronic lens. Therefore, in order to achieve high resolution requirements, it will be very important to shorten the distance (depth) between the electronic screen and the phosphor screen. In addition, as the angle of refraction of the electron beam increases, the difference in magnification between the central area and the edge area of the phosphor screen will increase. Therefore, large-angle refraction is not good for achieving high resolution. In this case, there is a known method in the prior art to arrange many independent small-sized image tubes, so that a high-resolution, large-screen product can be created. This type of method is extremely effective for large screen displays with large divided areas, which are designed for outdoor display screens. However, when this method is applied to the display of a medium-sized screen (for example, when the screen size is about 40 inches), the connection between the divided areas of the screen will be extremely significant, resulting in a low-quality picture. Therefore, when the display split by this method is used for home TV receivers or computer-aided design (CAD), the screen (please read the precautions on the back before writing this page) 丨 Install.

V. Description of Invention (2) The connection part on the screen will become a serious defect. On the other hand, U.S. Patent No. 4, 714, 856 has published a picture tube, many of which are arranged independently of the mine, and the screens of these picture tubes are integrated together. According to this image tube with an integrated phosphorescent screen, a vacuum package will consist of a panel with the inner surface of the phosphorescent screen, and a back plate opposite to the panel, a funnel-shaped structure next to the back plate And a neck structure placed on the funnel-shaped structure. The front panel is made of glass, and the back panel is made of glass or metal. In the case of this packaging structure, if the surface of the fluorescent screen becomes larger, it is necessary to increase the thickness of the panel or the backplane in order to withstand the load of atmospheric pressure (external pressure). In addition, we must provide a high curvature in the axial direction of the picture tube. Therefore, the reset of the package structure will become very heavy. In addition, a screen made of a picture tube of a panel having such a large curvature in the axial direction cannot be seen. In particular, the distance between the electronic screen sealed in the neck and the phosphor screen increases accordingly, and the magnification of the electronic lens is also affected by the reverse. In order to solve the above-mentioned problems, we especially need to provide panels with a relatively flat large area. In this case, we must also provide a support device within the package structure to support the load exerted on the panel by atmospheric pressure. A picture tube with such a support device has been published, for example, in the published Unexamined Japanese Patent Application (PUJPA) No. 64-1 1 ◦ 5 5 3. According to this picture tube, an extended plate-shaped support device will be provided between the lithographic panel and the back plate as a support to be drawn (please read the precautions on the back before writing this page)-install. Order. This paper scale is applicable to the Chinese National Standard (CNS) A4 specifications (210 X 297 mm)-4-81.9.25,000 A6 B6 Printed by the Employee Consumer Cooperative of the Central Bureau of Economic Development of the Ministry of Economic Affairs V. Invention Instructions (3) Empty lithography Atmospheric pressure on the packaging structure. Here is another example, in addition to the above-mentioned support device, there is a needle-shaped support device arranged in 0. If possible, this support device is preferably located outside the trajectory of the electron beam to avoid when the electron beam hits the support device There will be a shadow projected on the disc screen, and it is best to make the connection area between the support device and the phosphor screen as small as possible, so as to reduce the area of the non-light emitting area generated by this contact. However, there are still many structural problems, in which the elongated plate-shaped or needle-shaped supporting device is disposed between the panel and the back plate, and the structure to withstand the atmospheric pressure applied to the evacuated flat panel device is the same. For example, lengthening the pedestal support device has the following problems: (a) processing accuracy, (b) load-bearing strength, (c) fixing method, (d) cost, and so on. The needle-shaped support device has a problem (e), which increases the number of devices used for support. The above picture tube is extremely effective, especially when the screen size is large, but different problems still occur. For example, when this picture tube is used in a cathode ray tube that displays color images, it is also used in it. When a shadow mask screen is used as the color, a color picture tube with electric shutter is selected. First of all, the method of installing the screen will be a problem. In short, in the case of a traditional color picture tube with a spherical panel, the shielding screen is also spherical. In this case, by fixing the edge part of the mask to the metal frame (mask frame), the mask can be given practical mechanical strength, and it is easy for us to position the mask in advance with The position of the Lanmeng is set between the phosphor screens formed on the inner surface of the panel. However, (please read the precautions on the back before writing this page)-Binding. Binding.

Description of the invention (4) In the case of a flat panel, the shielding curtain must also be flattened, which will cause the shielding curtain Reduced mechanical strength. Therefore, in addition to fixing the green part of the edge of the shadow mask as in the prior art, the shadow mask cannot be easily placed at a predetermined relative position between the phosphor screens on the inner surface of the panel. Generally speaking, if you consider a flat screen or a column screen with a curvature in a single direction, as long as you apply tension to the screen and fix it on the metal structure of Qiang Le, you can provide the screen Sufficient mechanical strength, and the screen is bonded to the panel via the metal structure. However, in this way, if the size of the screen increases as the screen size increases, the tension applied to the screen also needs to increase. Therefore, a stronger metal frame is needed. In this case, not only does the weight of the entire picture tube increase, but also the joining device used to join the screen and the panel via the gold frame must also be constructed. In addition, sufficient space must also be provided to accommodate the joining device. Secondly, there is a question about the precise placement of the screen. The phosphor screen of a general color picture tube is formed on the inner surface of the panel on the basis of the image projected through the screen by using the light engraving method and the built-in screen in the picture tube. Therefore, if the distance between the screen and the inner surface of the panel (i-value) deviates from the preset value, the distance between the phosphorous thin layers will be affected, but the entanglement of the entire phosphorous phosphor screen will not be affected. bridle. On the other hand, in the case of a built-in phosphor screen, which is divided into many areas and scans each other's color picture tubes independently, the minerality of the phosphor screen is also projected adjacent to the screen The succession of images between regions is also affected by the value of 1. More specifically, when the SL-value is greater than the preset value, the shadow projected on the adjacent area (please read the precautions on the back before filling out this page). 装 · 定 '. 线.

In addition, when the phosphor screen uses a so-called main mask When made by the method, that is, when using an exposure mask or a dry flat plate, the distance between the screen and the inner surface of the panel with the phosphor screen must be correctly defined. If the value of _a_ cannot be determined, Then the electron beam cannot fall on the preset phosphor layer, the image areas between adjacent areas will overlap each other, or there will be gaps between the image areas. At the same time, although-value depends on the horizontal refraction angle or the placement distance of the screen , But the accuracy of the required value is about 0.05 mm. By the traditional color image The fact that the required manufacturing accuracy is about 0.5 mm seems that the accuracy of the one-to-one value required by us is quite high. In other words, it is difficult to achieve such a high accuracy with the traditionally well-known method. For example, The inter-patent patent application PCT / US87 / 02869 shows a picture tube in which the screen is installed on the inner surface of the panel through the joint assembly, that is, on the phosphor screen. The supporting state of the screen is two The end parts are connected to the bonding component. However, in the case of this structure, the bonding component cannot be installed in the central part of the phosphor screen, so as not to occur on the phosphor screen due to the collision of the electron beam and the bonding component Shadows, and areas that emit light without irradiation. Therefore, the joint can only be installed on the outer edge of the phosphor screen, and only the two ends of the screen can be supported by the joint. Therefore, the center of the screen The part cannot be supported by the joint component. Therefore, especially when the screen size is large, the central part of the screen may be easily distorted and deformed. At the same time, the image tube will cause a consequence that is difficult Cover with high precision (please read the precautions on the back before writing this page) -install.

Description of Invention (7) Supported by the first and second supporting parts, and the intermediary part of the curtain is supported by the central supporting part. The screen itself can be positioned with the phosphor screen in a blue position with high accuracy. In addition, each supporting portion is fixed to the inner surface of the second plate. Therefore, for example, even if the Chinese enterprise is located at the position facing the central portion of the phosphor screen, the electron beam emitted from the radiation device will not collide with the intermediary support portion, and the phosphor screen The formation of shadows, or the formation of non-light bright spots can be avoided. According to the present invention, the cathode ray tubes are all equipped with a fixing portion, which is locked to the inner surface of the second flat plate, and the supporting portions of the supporting device for supporting the screen are fixed to the fixing portion. According to the above structure, the fixed portion is pre-locked on the second flat plate with a material such as raw glass, and the supporting portion is completely welded to the fixed portion by laser welding at normal temperature. When the original glass melts and locks the fixed part on the second plate, we must fix the fixed part with the positioning frame and heat the relevant parts at high temperature (hundreds of degrees Celsius). Therefore, during the heating period, the temperature distribution of the phase portion will change, which will result in a decrease in the accuracy of locking the fixed portion. However, the support part can be fixed to the fixed part at low temperature by laser welding, and the low temperature can just ignore the effect of thermal expansion and the contraction of the phase-open part. Therefore, even if the accuracy of the locking fixing portion is slightly worse, the supporting portion can still be fixed at a predetermined relationship with the second flat panel and the screen with high accuracy. Therefore, through the process of connecting the screen to the support assembly, we can obtain a cathode ray tube with high assembly accuracy.

The cross section of the invention description (12), and fixed to the back The inner surface of the plate 12 is such that its longitudinal axis can extend in the horizontal direction. Compared with the phosphor screen, the structure of the screen 2 is that the electron beam penetration hole can only be formed in certain areas on the screen ( Effective area), these areas are the relative areas R 1, R2, R3… R20, which are necessary for the phosphor screen 17 to have a single image, and there is no breakpoint between the areas R1, R 2, R 3 ...

The area of the screen 20 and the edge portion of the screen 20 between the effective areas are fused On the screen support device 19. Thus, the screen 2◦ can be used by the support device 19 to interact with phosphorescence It is supported by the preset position of the screen blue. More specifically, the upper half of the screen 2 faces the longitudinal upper half of the phosphor screen, which is supported by the first support device 19a and the lower side of the screen 20 The half, facing the lower longitudinal half of the phosphor screen, is supported by the second support device 1 9 b.

Description of the Invention (13) The original glass is fixed on the inner surface of the back plate 12. Each supporting element 23 extends through the penetration hole on the screen 20. The contact surface 23a of each support assembly 23 is in close contact with the phosphor screen 17. More specifically, each support member 23 is disposed between the horizontally adjacent screen support members 19, and penetrates into the part of the screen 20 where the electron beam penetrating holes are not arranged. However, the support assembly 23 is not disposed between the adjacent first support assembly 19a or the adjacent second support assembly 19b. As shown in FIG. 4, the support assembly 23 is fixed on the back plate 12 so that their contact surfaces 2 3 a can be in contact with the black stripes of the phosphor screen 1 7 to scan the 0S area Rl, R2, R3, ••• RSO At the intersection, and make the longitudinal axis direction of the contact surface 2 3 a coincide with the direction of the black stripes. In addition, each contact surface 23a is provided with the center line of the corresponding black stripe 18 so that it will not be at least placed outside the longitudinal side edges of the black stripe. In this case, for example, when the placement points of the three-color phosphor layers 17B, 17G, and 17R are 0.6 mm, and the area ratio of the black stripes 18 and the entire phosphor screen 17 is 50%, each black stripe The width is 1.0 mm. Therefore, I hope that the width of the contact surface 23a of each plate support assembly 23 must be 0.01 mm or less. The contact surface 23a can be processed to a width of 0.01 mm or less using a polishing process. Before the vacuum envelope 14 is formed, the plate support assembly 23 will be placed on the back plate 12 and positioned on the black stripe 18 with an accuracy of approximately 0.03 mm.

Invention Instructions (14) Support Components 1 9 and the plate support assembly 23 are positioned on the inner surface of the back plate 12. After the inner surface of the back plate 12 is coated with a layer of primary glass, it is sintered. Thereby, the screen support assembly 19 and the plate support assembly 23 can be fixed to the predetermined position on the inner surface of the back plate 12. The screen 20 is welded to the screen support assembly 19 fixed to the back plate 12, and a tension will be applied to the screen in the following manner. The electronic grab 22 is sealed in the neck 21 of each vent tube 13. The panel 10 where the phosphor screen 17 is located, the side wall 1 1, the back panel 12 where the screen support assembly is located, the flat panel support assembly 23 and the screen 20 are all attached together, and at the same time there is a vent tube 13 with an electron gun 22 sealed on its neck It is positioned at the preset relative position, and then these parts are integrated with the original glass into an integrated whole-shaped element. After completion, this integrated package will be evacuated, thus completing a color cathode ray tube. In addition, there are many methods for manufacturing color cathode ray tubes. For example, according to a certain method, the panel 10 where the phosphor screen 17 is located, the side wall 11, the back panel 12 where the screen support assembly 19 is located, the flat panel support assembly 23 and the screen 20 are positioned at a predetermined relative position, and are combined It is one united by the original glass.

Description of the invention (15) The copies can also be supported by the curtain support assembly 19. As a result, the entire screen 20 can be correctly positioned relative to the phosphor screen 17. In the above-mentioned structure, by forming the screen supporting member 19 in advance with a predetermined process accuracy, the height of the screen coupling surface of the supporting member can be constant with the required accuracy. Therefore, the distance between the entire front surface of the screen 20 and the phosphor screen 17 can be maintained accurately. In addition, there is another advantage that each screen support assembly 19 does not require too high process accuracy. For example, in the case where the mounting point of the stripe-shaped three-color phosphor layer of the phosphor screen 17 formed on the inner surface of the panel 1 is 0.6 mm, and the width of each black stripe is about 0.1 mm, it is In order to arrange the phosphor layer, the overlapping width or gap of the electron beams emitted by the two adjacent electron guns 22 must be half or less than the width of the black stripes. In the case where the horizontal length Η of each region R1, R2, R3, ..., R20 of the cathode ray tube of this embodiment is 80 mm, the distance between the phosphor screen 17 and the deflection center of each deflection electrode 25 L (Fig. 5) is 56mm, and the distance q between the phosphor screen 17 and the screen 18 is 8mm. When the overlap width of the electron beams at the boundary of the regions Rl, R2, R3, ..., R20 is D (see Figure 8), the offset Aq generated by the preset q value will be expressed as △ q = D · (Lq) / (H / 2 + D) Therefore, the required precision of the q value of this cathode ray tube, that is, the required precision of the process of the screen support assembly 19 will be 0.06 mm.

Description of invention (16) First, the cathode ray tube can be a traditional, low-cost process method To mass production. Since the screen 20 of this cathode ray tube is flat and has no curvature, just like the flat panel 10, we hope to apply a force to the screen 20 so as to suppress the occurrence of thermal deformation or vibration . According to one method of applying a force to the screen 20 of the cathode ray tube of the present invention, when a force 26 acting in the direction of arrow 31 is applied to the screen support assemblies 19a, 19b, 19d, and 19e, the screen 20 Welded on the curtain support assembly 19 at the same time, so that the curtain support assembly can be elastically deformed and slightly bent, as shown in FIGS. 2 and 5. When the force applied in the direction indicated by the arrow 3 1 is released after welding, the screen 2 ◦ will generate a force applied to it by the restoring force of the deformed screen support assembly 19. In this case, tension will be applied to the screen 20 along the axial direction of the strip-shaped three-color phosphor layer. In a traditional color cathode ray tube, the tension will increase exponentially with the screen size. However, in the shadow-ray tube of the present embodiment, the screen 20 is roughly divided into many parallel areas by the screen support assembly 19. Therefore, the size of each area of the screen 18 between the screen supporting components will be approximately equal to the size (width) of the screen of a small-sized color and color picture tube. Therefore, the tension required to suppress the thermal expansion deformation or vibration of each area of the mask 20 will be approximately equal to the tension required for the mask of the small-sized color picture tube. For example, each support assembly 19 is formed by a U-shaped 20mm high and 0.8mm thick slab.

The shade 20 is placed in this state. In this way, a substantially uniform tension can be applied to the entire screen 20. Since the screen support assembly 19 can be fixed with high precision, the distortion or wrinkle of the screen 20 caused by the shift of the position of the screen support assembly 19 after installation will be avoided, and the tension of all areas of the screen 20 can be uniform Sentence distribution. In addition, as described above, the screen 20 is constructed so that the electron beam penetrating holes only exist at the effective area, that is, with respect to the areas R1, R2, R3, ..., R20 is used to form a single image without the phosphor screen A breakpoint will occur between the regions R1, R2, R3, ..., R2 0, and no electron beam penetration holes will be formed between the effective regions or the edge. Therefore, even if the electron beam scan exceeds the predetermined effective portion, no light will be emitted from the phosphor layer in the adjacent area of the phosphor screen 17, and the image can be displayed stably for an extremely long time. At the same time, since the mask 20 is located between the effective portion and the edge portion where there is no electron beam penetration hole, it is welded to the mask support assembly 19, so the mask is born due to welding The deformation caused by heat will be avoided. In addition, the plate supporting member 23 is also inserted between the effective portion and the edge portion which is not provided with the electron beam penetrating hole. Therefore, the screen support assembly 19 and the tablet support assembly 23 will not be scanned in the plaque field R1, (please read the precautions on the back before writing this page). Installed.

Before the panel 10, the side walls 1 1 and the back plate 1 2 and the ventilation tube 13 are combined and sealed with the original glass, the first and second fixing components 28, 30 and other parts with preset sizes and shapes must first It is positioned on the inner surface of the back plate 12. These fixing members 28 and 30 are fixed on the back plate 12 with original glass. In this case, we hope to lock the fixing components 28 and 30 on the back plate 12 only when these fixing devices are pressed against the back plate, so that the original glass 36 and 42 can be prevented from entering the fixing components 28 and 30 In the gap between the surfaces of the flat portions 32 and 38 and the back plate 12. The area of the plane portion 32 of each fixing component 28 is larger than the area of the curved portion of the screen support element 19, and the area of the plane portion of each second fixing component 30 is also larger than the area of each The area of the middle section of a plate support assembly 23 is large. Therefore, the fixing position for fixing the components 28 and 30 does not require extremely high precision. Next, as shown in FIG. 14, using the lower frame 46 and the higher frame 50 and other structures, the support assembly 23 is positioned on the second fixing assembly 3 ◦ which is fixed to the back plate 12. The lower frame 46 has a horizontal reference plane 44H and a vertical reference plane 44V at one end of the horizontal reference plane 44H. The upper frame 50 has a reference surface 48 on which the flat plate support assembly 23 is placed. More specifically, the back plate 12 on which the first and second fixing assemblies 28 and 30 are joined is placed on the horizontal reference surface 44H of the lower frame 46, with the fixing assemblies facing upward. One end surface of the back plate 12 is joined to the vertical reference surface 44V at the tail end. Therefore, the backplane 12 is positioned accordingly. The plate support assembly stands on the second fixing assembly 30 on the positioned back plate 12. The upper frame 50 is placed under the proper pressure on the side of the support L paper to use China National Standard (CNS) A 4 specifications (2〗 0 father 297 male cage) -22-A6 (please read the precautions on the back first Write this page).

When one end surface of the upper frame 50 is adjacent to the vertical reference surface 44V of the lower frame 46, a force in the direction indicated by the arrow 53 will be applied to the top portion of the support assembly 23 through the block 52 And the support assembly 23 is pressed against the reference surface 48 of the upper frame 50. Therefore, the positioning method of the support assembly 23 is effective. The distance L1 between the end surface of the upper frame 5 and the rightmost reference surface 4 8 of the upper frame 50 and the distance L 2 between the two adjacent reference surfaces 48 are accurately defined; Thereby, the flat support assembly 23 can be surely positioned using the upper and lower frames 50 and 46. After that, the positioned flat plate support assembly 23 can be welded to the corresponding second fixing assembly 30 by laser welding. Following the above steps, the screen support assembly 19 is placed on the first fixing assembly 28 without using the upper end frame 50, and another design is used for the support assembly 19 using the upper end frame (not shown in the figure). Under suitable pressure, place it on the support assembly 19. After the screen support assembly 19 is positioned in a similar manner as described above, the support assembly 19 will be welded to the corresponding first fixing assembly 28 by laser welding. After that, the screen 20 is welded to the screen support assembly 19 in the same manner as in the first embodiment. After that, the screen support assembly 19, the flat plate support assembly 23 and the back plate 12 of the screen 20 are fixed thereto, and the outer seal 14 can be constructed, and a cathode ray tube is completed. There are many ways to construct an outer seal. According to an example, a panel 1 having an inner surface equipped with a phosphor screen 17 has a back plate 12 on which support components 19 and 23 are fixed, and an electron gun 22 is sealed on its neck (please read the precautions on the back side first) (Write this page) 丨 Packing.

V. Description of invention (22) 2 1 The ventilation tube 13 in the whole is fixed by a rack (not shown in the figure) under the preset positioning threshold. At the same time, the screen is placed in this structure. These members 10, 11 and 12 are then combined with other components in raw glass. After assembly, the outer envelope is evacuated so that a cathode ray tube can be completed. Like the first embodiment, the screen 20 is welded to the screen support assembly 19 when the screen support assemblies other than the central support assembly 19c are elastically deformed slightly inward, so that tension can be applied to the three The direction of the color phosphor layer expanding outward. In the above-mentioned embodiment, the front panel, the side wall, the back panel and the ventilating cylinder are all combined with the original glass pot to carry the outer seal. However, the externally sealed components can be combined without using raw glass. For example, the panel and the side wall may be integrated, or the separately formed panel and the inverted wall may be joined together by welding. According to the second embodiment of the above structure, in addition to the advantages of the first embodiment, the following advantages can be obtained. That is, in the second embodiment, both the first and second fixing members 28 and 30 are fixed to these fixing members. The accuracy of the positions of the support assemblies 19 and 23 relative to the backplane 12 is defined by the accuracy of the positions of the support assemblies 19 and 23 relative to the fixed assemblies 28 and 20, not by the accuracy of the positions of the fixed assemblies relative to the backplane Define. Therefore, when the coated raw glass is sintered to lock the fixing components 28 and 30 on the back plate 12, there is no need to wait for a high-precision positioning frame (even if a high-precision frame is used, the simple structure enough). In the case where the width of the curved portion of the screen support assembly 19 and the diameter of the central portion of the flat support assembly 12 are 10 mm, the width of the first fixing assembly 28 and the diameter of the second fixing assembly 30 are about 15 mm At the same time (please read the precautions on the back before writing this page) 丨 Installation _ Order_ -The size of the line paper is suitable for the specifications of a Yuanjia kneading (CNS) A 4 (210 X 297 mm) -24- 81.9.25,000 Printed by R Industry and Consumer Cooperative Cooperative of Central Government of the Ministry of Economic Affairs * A6 B6 V. Description of invention (23) Provides sufficient tolerance for the positioning of supporting components 19 and 23. Therefore, even if some deflection occurs when the fixing assemblies 28 and 30 are locked with the original glass on the back plate, the screen support assembly and the plate support assembly can be accurately positioned without the need to move the fixing assembly. In addition, the curtain support assembly 19 and the flat panel support assembly 23 are fixed to the fixed assemblies 28 and 30 of the counter seat by laser welding when these support assemblies are positioned. Therefore, the support and fixing components are welded and fixed at approximately normal temperature without heating to a high temperature range. Therefore, the fixing of the support members 19 and 23 is neither affected by thermal expansion nor by the change in temperature distribution. The change in temperature distribution may occur when the support members 19 and 23 are fixed with the original glass. In this way, the support assemblies 19 and 23 can be correctly fixed at predetermined positions. The first and second fixing members 28 and 30 have corrugated edge portions 34 and 40 formed around the plate portions 25 and 30 to allow the curtain support assembly 19 and the plate support assembly 23 to be installed thereon on. Raw glass 36 and 42 are plated on these peripheral parts 34 and 40 and sintered together, whereby the peripheral parts 34 and 40 can be fixed on the back plate 12. In this case, the coated raw glasses 34 and 40 will enter the grooves of the peripheral portions 34 and 40, and securely lock the fixing members 28 and 30 to the back plate 12. More specifically, when the chief screen 20 is to be fixed on the first fixing component 28 of the screen supporting component 19, in order to apply a force to the screen 20, the screen will be directed from the side wall 11 to the supporting component 19 When the internal force is slightly distorted, it is welded to the support assembly 19 (please read the precautions on the back before writing this page) 丨 installation.

Therefore, an external force corresponding to the direction indicated by arrow 54 acts on the first fixing assembly 28. However, according to the above structure, the fixing force of the fixing assembly 28 in the direction indicated by the arrow can be greatly increased, so that the situation where the fixing assembly 28 peels off or floats from the back plate 12 can be avoided. Unlike the case where the vaporized film is formed on the surface of the fixed component in order to lock the fixed component to the back plate, according to the second embodiment, the green parts 34 and 4 on the side of the fixed component are plated with the original glass 36 and 42, Mainly to provide a way to fix components. Therefore, the locking of the fixing components 28 and 30 is extremely stable and will not be affected by the bad vaporization film or deformation of the edge portions 26 and 31 of the fixing components 28 and 30, the buckling and the pollution. The first fixing assembly 28 for mounting the screen support assembly 19 and the second fixing assembly 30 for mounting the plate support assembly 23 have flat portions 32 and 38, respectively. The flat portions 32 and 38 are tightly joined to the back plate 12 so that no original glass will be placed between the flat portions 32 and 38 and the inner surface of the back plate 12. 5mm。 If the fixed component is locked with the original glass placed between it and the inner surface of the back plate 12, the thickness of the original glass will change from 0 to 0. 5mm. However, in the shape of this embodiment, the height of the fixing members 28 and 30 is only defined by the thickness of each fixing member. By accurately defining the thickness of each fixed component, the height of the fixed components 28 and 30 after being fixed on the back plate 12 can be accurately maintained within a preset range, or only a small change, regardless of the plating How much is the original glass 36, 42? Therefore, the screen support assembly 19 and the flat support assembly 23 are fixed after the first and second fixing assemblies 28 and 30 (please read the precautions on the back before writing this page).

Description of invention (25) The height can be maintained with extremely high precision. The inventors used various computer simulations and experiments to study the use of actual vacuum packaging. They found that the deformation of the vacuum-encapsulated panel 10 has a preset impedance to atmospheric pressure, because the load of atmospheric pressure is almost zero at the part in contact with the plate support assembly 23, and the center between adjacent plate support assemblies The part has the largest value (about 0.5 mm). This result is obtained when all the flat support members 23 are of equal height and the load caused by atmospheric pressure is uniformly applied to all the support members 23. If some of the support assemblies 23 do not have a predetermined height, the load due to atmospheric pressure will act unevenly on the panel. The unevenness of the load will be most pronounced when the central component of the three adjacent planar support components 23 is higher than the other components. In order to examine the effect of this non-uniform load, the inventors examined the change in the resistance of the package 14 to atmospheric pressure as the height of the plate support assembly changes. I found that although the guaranteed strength of vacuum outsourcing is three times the value of atmospheric pressure, when the height of a certain flat support component 23 is higher than other support components by 50% of the maximum deformation, the resistance to atmospheric pressure of vacuum outsourcing will decrease About 30%. However, when the height of a certain support component 23 is only 20% higher than the maximum deformation value of other support components, the strength against atmospheric pressure will not change. From the above results, in the cathode ray tube of this embodiment, the accuracy required for the height of the plate support assembly 2.3 is 0.1 mm, which is equivalent to 20% of the maximum deformation of the panel. In fact, this value is not as high as the cracking accuracy of the support assembly 23 with a wedge-shaped tip, and this result shows the support group (please read the precautions on the back before filling in this page) —installation-order · line '夂The paper scale is applicable to the National Standards (CNS) Grade 4 (210 X 297 mm) -27-81.9.25,000 A6 B6 Printed by the Central Consumers Agency of the Ministry of Economic Affairs Employee Consumer Cooperative V. Invention Instructions (26) Pieces 23 Mass production becomes possible. In addition, this value indicates that the change in height of the support component is low, and we can compare it with the following situation: when the fixed component is combined with the original glass rose placed between it and the inner surface of the back plate, coated in 5mm 的 范围 内 受 动。 The thickness of the original glass between the inner surface of the back plate and the fixed component will probably be in the range of 0 to 0. 5mm. In addition, since the screen support assembly 19 can be easily manufactured with a preset process accuracy, the height of all screen support assemblies 19 can be made constant. Therefore, the positioning accuracy of the screen 20 joined to the screen support assembly 19 can be as high as possible, and the distance between the inner surface of the panel 10 and the surface of the screen 20 can also be accurately defined. The accuracy of the _g_-value depends on the process accuracy of the screen support assembly 19, which is similar to the case of the flat support assembly 2 3. _a_-The accuracy of the value is actually no higher than the accuracy of the general single parts. As explained in the above embodiment: the allowable ja_-value error Aq can be used as Aq = D · (L-q) / (H / 2 + D) in the following table. The value required is the accuracy required in the cathode ray tube of this embodiment, that is, the process accuracy required for the screen support assembly 19 is 0.06 mm. This accuracy can be achieved with a traditional low-cost manufacturing method. As described above, according to the second embodiment, the joint position and height of the flat panel support assembly can be correctly defined, and the panel and the back panel can evenly bear the load applied by the atmospheric pressure, so it can be broadcasted to fully withstand Cathode ray tube with load brought by atmospheric pressure. In addition, since the joint position and height of the screen support assembly can be accurately defined, the distance between the phosphor screen and the screen can also be accurately defined. Therefore, we can get an image that can show "colorless" shift.

Description of the invention (27) The present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit of the present invention. For example, in the above-described embodiments, the first to fourth curtain support assemblies 19a, 19b, 19d, and 19e all have a substantially U-shape. However, these components can have other cross-sections, such as I-shaped cross-sections. The hardness of the central support member 19c can strengthen the possibility of preventing them from collapsing. In the above embodiment, the screen is welded to all supporting components. However, the screen can also be welded only to the first and second support members located at both ends of the strip phosphor layer in the extending direction, and only need to be in contact with the other third, fourth and central support members. In this case, the distortion of the screen can also be avoided by the screen support assembly, and the screen can be fixed at a predetermined position related to the phosphor screen. In this situation, I hope that the screen can press the screen toward the third, fourth, and central support components by forcing devices such as springs. In the above-described embodiment, the first and second fixing assemblies to which the screen support assembly and the plate support assembly are mounted are both in the shape of a flat plate. However, these fixed components can also be formed into a three-dimensional shape with a certain thickness. Only the side and back plates of these fixing components can be plated with original glass roses, and these fixing components are fixed to the back plate by sintering of the original glass. In addition, in the above-described embodiment, the screen support assembly is substantially U-shaped in cross section. When these support components are applied to a cathode ray tube with a larger screen size, the color cadmium shift may occur due to the thermal expansion of the screen caused by the impact of the electron beam. More specifically, where the color is shifted to the edge of the screen, where the thermal expansion effect will accumulate will be more pronounced. Therefore, please make this one shade (please read the precautions on the back before filling in this page). I install. Order.

V. Description of the invention (28) When the polar ray tube is combined with a larger screen, it is best to place the screen vertically The strip phosphor layer is divided into many components in the horizontal direction of the longitudinal axis. By cutting the screen, the accumulation of thermal expansion can be reduced, thereby avoiding color shifts. In the above embodiment, the edge portions of the first and second fixing members have dentate ridges. However, these edge portions may have wrinkles of other shapes, for example, zigzag wrinkles as shown in FIG. 15 or corrugated wrinkles as shown in FIG. 16. In these cases, as the advantages obtained in the second embodiment, the points can be obtained in the same way. In addition, as shown in Figure 17, the edge part of the fixing component may be provided with wrinkles in addition to the surrounding direction, but also in the height direction. At the same time, the edge part of the fixed element may only be formed on a part of the edge of each fixed element, instead of the integral green. In addition to this, the original glass rose can be continuously plated on the edge of each fixed component instead of being continuously coated. As explained above, it is important that the flat part of the fixing component is closely in contact with and locked with the inner surface of the back plate, and the purpose is to reduce the change in height of the curtain supporting component and the flat supporting component. However, even if the original glass coated on the edge of the fixed component enters between the flat part of the fixed component and the back plate during coating or sintering, as long as the original glass is extremely small, the accuracy will not be a problem, and The same advantages as the above embodiment can still be broadcast. In the above embodiment, the first fixing component for fixing the screen supporting component and the second fixing component for fixing the flat panel supporting component are independently arranged. But these fixed components can also form a horizontal group of skulls together (please read the precautions on the back before filling the nest page). Install.

Description of the invention (29) In the above embodiment, the screen support assembly and the flat panel support assembly are fixed to the back plate through the fixing assembly. When the fixed component is used, various components can be fixed by applying the original glass in only one direction of the fixed component. Therefore, the above-mentioned structure can be used not only for the fixing of supporting components, but also for the fixing of other components, such as: a terminal panel for providing high voltage of the yang dian, a reference plane for measuring and setting the position of various components, etc. The above embodiment is specifically designed for use as a cathode ray tube of a color picture tube with a screen. However, the present invention can also be applied to other cathode ray tubes, such as a monochromatic picture tube without a screen and a color picture tube of an electron beam marking type. The above embodiment is specifically directed to a cathode ray tube having an electron gun as an electron beam radiation device. However, the electron beam emitting device can also be equipped with a set of linear electron discharge sources. In addition, in the above embodiment, the electron beam is directed toward the cadmium in an electromagnetic manner by the deflecting electrode. However, the electron beam can also be deflected electrostatically using an electrostatic deflection plate. (Please read the precautions on the back before writing this page) — Binding. Ordering.
