M273013 八、新型說明： 【新型所屬之技術領域】 本創作係關於一種背光模組的光源裝置，特別係關於 一種可應用於液晶顯示器之直下式背光模組的光源裝置。 【先前技術】 液晶顯示(LCD)技術一向被應用於筆記型電腦、行動電 話、數位相機、攝錄影機、PDA等攜帶式的電子產品中。 除了這些較小型的攜帶式的產品之外，近來大尺寸的液晶 面板製作技術也日漸成熟。例如，桌上型液晶顯示器正逐 漸取代CRT螢幕。液晶電視挾其體積輕巧的優勢，目前也 正在市場上與傳統電視競爭。液晶面板(LCD panel)係為此 領域中最關鍵的顯示元件，然而其本身並不發光，需要藉 由一背光源的設置才得以進行顯示。現今已存在有許多種 背光源技術，而在大尺寸（約20吋以上）的液晶顯示器產品 中’經4使用直下式背光权組(bottom lighting module)， 以作為液晶面板的背光源。 請參照圖一，圖一顯示一典型的直下式背光模組立體 爆炸圖。背光模組10之中，複數個燈管12係平均地排列 於底板14之上，底板14上表面通常會設置有反射片ΐβ， 用以使得燈管12發出的光線向上反射，光線在經過擴散片 18之後則可提供給背光模組1〇上方的一液晶面板2〇。擴 散片18可使得通過的光線產生散射，避免使用者觀看液晶 面板20時，會因為燈管12較強的亮度而直接看到燈管12 的形狀，產生亮度不均的感覺。其中，背光模組1〇因為其 燈管12係直接設置於液晶面板20的下方，因此通常將之 M273013 稱為直下式背光模組（bottom lighting module)。而如 圖一所示，背光模組10更包括有複數個燈管固定架13， 用以將該些燈管12固設於底板14上方一預定高度的位 置，如此一來可使得背光模組10整體的出光效果更佳，且 有助於散熱。燈管固定架13的功能除了將燈管12固設於 底板14上方敢高度之外，其在底板14平面上的設置位 置也很重要，因為這會影響燈管12的定位與分布情形，而 影響背光模組10整體出光效果的均勻性。 請翏照圖二’其縣圖—背光模組結合後局部放大 圖。在圖-背光模組1〇之中，關於該些燈管12之電源的 t、、、’s通$疋藉由將燈管12的燈管電極軸I。架設在電壓

Description of the new type: [Technical field to which the new type belongs] This creation relates to a light source device for a backlight module, and particularly to a light source device for a direct type backlight module of a liquid crystal display. [Previous Technology] Liquid crystal display (LCD) technology has been applied to portable electronic products such as notebook computers, mobile phones, digital cameras, camcorders, and PDAs. In addition to these smaller portable products, the manufacturing technology of large-size liquid crystal panels has also recently matured. For example, desktop LCDs are gradually replacing CRT screens. LCD TVs, due to their lightweight advantages, are currently competing with traditional TVs in the market. The liquid crystal panel (LCD panel) is the most critical display element in this field. However, it does not emit light by itself, and it is necessary to set a backlight to display it. There are many kinds of backlight technology now. Among large-size (about 20 inches or more) LCD products, direct lighting backlight modules are used as backlight sources for LCD panels. Please refer to Fig. 1. Fig. 1 shows a typical exploded view of a direct type backlight module. In the backlight module 10, a plurality of lamp tubes 12 are evenly arranged on the bottom plate 14. The upper surface of the bottom plate 14 is usually provided with a reflective sheet ΐβ for reflecting the light emitted by the lamp tube 12 upward, and the light is diffused. The sheet 18 can be provided to a liquid crystal panel 20 above the backlight module 10. The diffusion sheet 18 can cause the passing light to be scattered, avoiding that when the user looks at the liquid crystal panel 20, the shape of the lamp tube 12 can be directly seen due to the strong brightness of the lamp tube 12, and a feeling of uneven brightness is generated. Among them, the backlight module 10 is generally referred to as a bottom lighting module (M273013) because the lamp tube 12 is directly below the liquid crystal panel 20. As shown in FIG. 1, the backlight module 10 further includes a plurality of lamp tube fixing frames 13 for fixing the lamp tubes 12 at a predetermined height position above the bottom plate 14, so that the backlight module can be made. 10 The overall light output is better and helps to dissipate heat. In addition to fixing the lamp tube 12 to the height above the bottom plate 14, the position of the lamp tube fixing frame 13 on the plane of the bottom plate 14 is also very important because it will affect the positioning and distribution of the lamp tube 12 and affect The uniformity of the light output effect of the backlight module 10 as a whole. Please click on Figure 2 ’its county map—a partial enlarged view of the backlight module. In the figure-backlight module 10, the power sources t, ,, and s of the lamp tubes 12 are communicated through the lamp electrode axis I of the lamp tube 12. Erected on the voltage = connecting plate 15, and then welding the lamp electrode shaft 121 and the voltage series plate 15 with solder 17. In this way, the lamp tube 12 can be electrically connected to the voltage series plate 15, and then Get power. However, the welding procedure generally has the disadvantages that it is not easy to shorten the working hours and the cost is high. In addition, in the manufacturing process of the backlight module 10, heavy work is inevitable (simplified possibility. It is not easy to take the lamp 12 out of the soldering tube!), And the same reason After the LCD has been used for a period of time, it will no longer emit light normally due to the end of the product's life. During the process of placing and g, it will also encounter the problem of difficult to remove the lamp 12. It is typical of uΛ 1G. The silk order scarf is usually entered after the bottom tube is fixed ~ the lamp tube fixing frames 13 are installed, and the lamps f 12 have been fixed on the bottom plate 14 through the lamps 13 ㈣ The steps of the polar axis 121 and the flap plate 15. This is because the lamp tube 12 is not fixed to the base plate M M273013 on the plane by the lamp tube holder 13 before the lamp tube 12 is difficult to be positioned directly. Problem After welding, the lamp tube 12 will be fixed on the voltage series board by solder 17. In this way, the function of the lamp tube holder 13 to control the positioning and distribution of f 12 will be meaningless. However, it is not shown in Figure 2 It is difficult to find that, in the backlight module 10, the solder 17 and the voltage series board 15 have at least the lamp tube 12 fixed. The high-level picking set on the bottom plate 14 overlaps with some of the lamp tube fixing frames 13. τ knife month b Shangxing's above-mentioned conventional technology overview of direct-type backlight modules promotes the creation of costs. In Under the situation of increasing competition in the industry, how to avoid the use of unnecessary components, make the production process more precise, shorten the processing time, maintain the existing product and be cost-effective? This is the direction focused on the technology research and development process, which can improve the competitiveness of the industry. Moreover, there is still a lack in conventional technology-a kind of ^ enough to make the light tube touch the 1 {) module production process needs to be heavy, or need When the lamp tube 12 is replaced, it is known that the backlight phase 1n is inadequate for materials and fields. The Yuexian Group 10 has a design convenience [new content] for the light source of a backlight module. Various disadvantages of 彳 m polar axis welding in series. Avoidable-the purpose is to provide-a direct type backlight module, to avoid the use of unnecessary components. Another program-the goal is to make the production of custom material modules more than four, and can shorten the processing time. M273013 Another purpose of this creation is a direct type backlight module, which has better convenience when reworking or replacing lamp officials. The creative system provides a direct type backlight module, which includes at least one lamp officer, a bottom plate, a voltage series plate, a reflection sheet, and a diffusion sheet. The lamp officials are evenly arranged on the bottom plate. A reflective sheet can be provided on the upper surface of the bottom plate to make the light emitted from the lamp tube reflect upward. After passing through the diffuser sheet, the light can be provided to a liquid crystal panel above the backlight module. The diffuser sheet can cause the light to be scattered and leave the backlight module uniformly, avoiding the user from viewing the liquid crystal panel, because the strong brightness of the lamp tube directly sees the shape of the lamp tube, resulting in money with uneven brightness. The serial connection board is responsible for supplying current to these lamps. One of them, each lamp has a lamp electrode shaft, which extends outward from the side end of the lamp, so that the electric current passes through the lamp. The a and f cascading plates have a plurality of stamped joints, which are used to combine the electrode shaft of the lamp tube and electrically connect the lamp tube and the voltage cascading plate. In one embodiment, the stamping joint includes a first metal sheet, which is fixed to the lamp electrode shaft from one side of the lamp electrode shaft, and the lamp tube and the voltage series board are electrically connected. In other embodiments, the number of metal pieces of the electrode shaft of the ring-shaped lamp tube is increased, and a limiting piece can be provided at a position corresponding to one end surface of the electrode shaft of the lamp tube to limit the direction of the lamp tube extending parallel to the axis of the lamp tube. mobile. In addition, the present invention also provides an embodiment, in which the stamping joint system includes a first metal sheet and a second metal sheet, which respectively hold the lamp electrode shaft from the two sides of the lamp electrode shaft. The direct-type backlight module provided by this creation is a thin stamping technology to form a plurality of stamped joints for the voltage series board, and the lamps are electrically connected with the clock. In the step of forming the car at the initial stage of the formation of the stamping joint ^ M273013, the position of the plurality of tilting tubes can be accurately determined. Since the stamping joint has the function of positioning the lamp tube, the feather knowledge and tube can be omitted. Fixed control. And, this technology does not need to know that two / dry-connected individual lamps are needed. The lamp electrode shaft system of a plurality of lamps can be placed with a voltage = the silent position on the connection board. All the lamps are combined. Therefore, excerpts can effectively reduce processing time. = Outside ”In the need to re-jade or set the lamp, this creation also provides convenience that is not known in the art. This creation not only improves the shortcomings of the conventional technology, but also the advancement in cost and security will provide the industry with considerable progress and better competitiveness. [Embodiment] 凊 Referring to FIG. 3, FIG. 3 shows a direct-type backlight module of this creation. The direct type backlight module 30 includes at least one lamp tube 32, a bottom plate 34, a voltage series plate 35, a reflection sheet 36, and a diffusion sheet; 38. The light tubes 32 are evenly arranged on the bottom plate 34. A reflection sheet 36 may be provided on the upper surface of the bottom plate 34 so that the light emitted by the light tube 32 is reflected upward, and the light may be provided to the backlight module 3 after passing through the diffusion sheet 38. A liquid crystal panel 20 above. The diffuser sheet 38 can cause light to be scattered so as to leave the backlight module 30 evenly, avoiding that when the user views the liquid crystal panel 20, the shape of the lamp tube 32 can be directly seen due to the strong brightness of the lamp tube 32, resulting in brightness. Uneven feeling. The voltage series board 35 is responsible for supplying current to the lamps 32. Please refer to Fig. 4 '. Fig. 4 is an enlarged view of a part of the back-lit backlight module of Fig. 3 in combination. It can be seen from FIG. 4 that the lamp tube 32 has a lamp electrode shaft 321, which is located at one end of the lamp officer 32 and is used to pass current into the lamp tube 32. On the other hand, the voltage series board 35 includes a stamped joint 351 and a voltage M273013 352 to provide current. And Chong Erkou 4 351 is stored in the corresponding lamp electrode car system to the electric dust series board 35 to rub,… and _, and to shape the lamp tube to combine with the lamp tube gang _ person electric I string The connection board body 352 is electrically connected. In the embodiment shown in FIG. 4, the Chongli tablet 35Π, a second all-generic tablet = I351 series include-the first metal restriction tablet heart Ganshi> belongs to a younger three metal # 3513 and 〆, making 3514. Among them, the first-metal sheet 351 tube electrode is drawn 321; and the third metal sheet 3513 / general sheet 11 has the same side ring-fixed tube electrode shaft 321. Department 4 is placed at a position corresponding to the -end face of the electrode axis 321 of the lamp tube to limit the movement of the lamp tube 32 in a direction parallel to the axis of the lamp f 32. = The parent picture 1 The unfamiliar backlight module 10 uses solder tin to freshly connect the official electrode shaft 121 and the voltage transfer board 15. This creation uses stamping knots: '351, to combine and fix the lamp tube electrodes. Shaft 321 (shown in Figure 4), and achieved the purpose of electrical connection on the same day. Please refer to FIG. 5A. The forming of the stamped joint portion 351 uses a stamping machine. First, the mold stamps the voltage series plate to form the stitching line 353 as shown in Figure 58. If you connect $, as shown in Figure 5 ^, 'use the mold to punch the voltage series plate 35 in the range of the seam and line 353' to make some of the Lai Zhuan plate 35 Wei; for the towel, use the appropriate rig and control And the pattern defined by the pre-formed stitches 353 can form the first metal sheet 3511, the second metal sheet 3512, the third metal sheet 3513, and the restriction sheet 3514 as shown in FIG. Various shapes. Although the stamped joint 351 shown in this embodiment shown in FIG. 4 includes M273013 and four sheet-like structures, it is not a simple structure in terms of structure. However, the current technology of punching and forming can reach as shown in Figure 5A and Figure 5B, only by forming the stitches Qi 3, and making the electric serial connection plate 35 within the range of the stitches 3 off. The Chongli step completes the production of the female coupling portion 351. Among them, a plurality of molds are used to form all the stitches 353 at the same time, and a plurality of molds are used to simultaneously lift up the sheet-like structures and mold them, thereby achieving the above-mentioned purpose of making the steps only relied on. In the same way, f is shown in Fig. 3 as a straight TM wire group with 30% of the number of healthy tubes, and «the formation of a plurality of stamping and bonding portions 351 requires only two stamping steps. On the other hand, the use of stamping technology is beneficial to these lamps 32 12-bits-* the position where these lamps 32 will be combined can be accurately positioned when forming the stitching 353, effectively improving The problem that the conventional technology is difficult to locate when the lamp electrode shaft 321 is combined with a fresh connection is used. Because of the f-mode and group 30 in this creation, even the lamp of the conventional technology, Lu Guzhen, can be omitted (13 in Figure 2); these lamp tubes 32 can be fixed by using the stamping joint 351, whether it is The height above the wire 34 or its distribution position on the plane of the bottom plate 34 can be positioned by using the stamping joints. Another advantage of this creation is that the stamped joint portion 351 composed of a metal sheet does not have the problem that it is difficult to remove the lamp tube by the conventional technology. Due to the extension of the metal material itself, when the lamp f 32 needs to be removed, the creation has better convenience than the conventional technology. Therefore, whether it is in the production of the backlight module 30, it is necessary to pay for money, and it is not clear that it is no longer normal because of the end of the life of the product. It is also very convenient to remove the lamp f 32 and reassemble 11 M273013 to install the lamp 32. : = The example shown in Figure 4 at first shows that there are four sheet-like structures in which the red house combination 4 351 includes the brother-metal 4 3511, the second metal 4 3512, the third metal sheet 3513, and the limiting sheet 3514. Knowing that the technical field is a word, when it is known that the implementation of excerpts can also omit some of the sheet-like structures, such as the second metal sheet 3512, the third metal sheet test, and the restriction sheet 3514, all can be omitted. The first metal sheet 35mm ring-fixed lamp tube electrode shaft 321 can implement this creation. Alternatively, the county-level structures and combinations of these sheet-like structures can also be achieved to achieve the same implementation mode as the original materials. In addition, since no matter how many sheet-like structures, this creation can be completed in the case of two people stamping steps, so if you go further than the four sheet-like structures-further increase the use of other similar sheet-like structures, It should also be included in the spirit of this creation. Please refer to FIG. 6A, which shows another embodiment of the present invention. In this embodiment, the stamped joint portion 351 includes a fourth metal piece 3515, a fifth metal piece 3516, and a restricting piece 3514. Among them, the fourth metal sheet 3515 and the fifth metal sheet 3516 hold the lamp electrode shaft 321 from both sides of the lamp electrode shaft 321. This embodiment is mainly different from the above embodiment in that the punching joint portion 351 combines the lamp electrode shaft 321 in a clamping rather than a ring manner, and requires the cooperation of at least two sheet structures. The method is the same as above, only two stamping steps are required. And using a different die in the punching machine, another embodiment as shown in FIG. 6B can be punched out. FIG. 6A and FIG. 6B are embodiments in which the lamp electrode shaft 321 is combined in a clamping manner, which has better convenience when the lamp tube 32 needs to be removed or reassembled. 12 M273013 Sure, then _ 疋 The original creative embodiment shown in Figure 4, Figure 6A or Figure 6B, in which solder can still be used to further improve assembly stability after the structure shown in the figure is completed. In the embodiment of FIG. 4, dry tin (not shown) can be soldered between, for example, the first metal sheet 3511 and the second metal sheet 3512, or the second metal sheet 3512 and the third metal sheet 3513. between. For the embodiment of FIG. 6A or FIG. 6β, solder (not shown) can be soldered between the fourth metal sheet 3515 and the fifth metal sheet 3516. In this way, the combination of the lamp electrode shaft 321 and the voltage series plate 35 can be further stabilized. As mentioned above, the direct-lit backlight module provided by this creation uses the technology of punching type to form a plurality of punching joints on a secret plate to combine and electrically connect the lamp tube. In the step of forming stitches in the initial stage of forming the stamping joint, the position of the plurality of lamps can be accurately defined. _The compression joint has the function of a slave lamp, so the knowledge can be omitted. Use of lamp holders. Moreover, this creation does not require the welding of individual lamps as in the prior art. The lamp electrode shaft system of a plurality of lamps can be placed at a predetermined position on the voltage series board. In a single stamping step, all the new tubes will be used. The combination is complete. Therefore, this creation can effectively reduce the processing time. In addition, when it is necessary to rework or replace the lamp, this creation also provides convenience that is not known in the art. This creation not only improves the shortcomings of the conventional technology, but also advances in cost, that is, the processing time, and provides the industry with considerable progress and better competitiveness. ^ Although the creation is exemplified as above with a better example, it is not intended to limit the creation of the creation and the entity of the creation. It is only limited to those who implement the above. When other components or methods can be easily understood and used ^: 目 刀 同 员 13 M273013 Work and Fan _ Zuo Zhi Xiu [Simplified illustration of the diagram] The above will be easily understood
