Description
本發明係提供一種背光模組及其固定蓋,尤指一種可固定纜線之背光模組及其固定蓋。The invention provides a backlight module and a fixing cover thereof, in particular to a backlight module capable of fixing a cable and a fixing cover thereof.
液晶顯示器中的液晶顯示面板(Liquid crystal display panel,LCD panel)是關鍵零組件之一,由於液晶本身不發光,背光模組之功能即在於供應充足的亮度與分佈均勻的光源,透過簡潔有效之光機構轉化成高亮度且均一輝度的面光源產品,而背光模組發出的光線經由液晶的轉換使液晶顯示面板能正常顯示影像。液晶顯示面板現已廣泛應用於監視器、筆記型電腦、數位相機及投影機等具成長潛力之電子產品,尤以筆記型電腦及LCD監視器等大尺寸用面板需求最大,也因此對於背光模組需求成長也日趨強烈。The liquid crystal display panel (LCD panel) in the liquid crystal display is one of the key components. Since the liquid crystal itself does not emit light, the function of the backlight module is to supply a sufficient light source with uniform brightness and distribution, which is simple and effective. The light mechanism is converted into a high-brightness and uniform brightness surface light source product, and the light emitted by the backlight module is converted by the liquid crystal to enable the liquid crystal display panel to display an image normally. LCD panels are now widely used in electronic products with potential for growth, such as monitors, notebook computers, digital cameras and projectors, especially for large-size panels such as notebook computers and LCD monitors. Group demand growth is also growing stronger.
請參閱第1圖,第1圖係為習知一背光模組10與一液晶面板11之結構示意圖。背光模組10主要由一發光源(例如冷陰極螢光管、熱陰極螢光管、發光二極體)14、一反射板(Reflector)16、一導光板(Light Guide Plate)15、一擴散片(Diffusion Sheet)13、一稜鏡片(Brightness Enhancement Film)12及一外框17等組件組裝而成。發光源14一般為一冷陰極射線管,發光源14射出的光線進入導光板15後,會導引射入的光線將其分佈成均勻的面光源,反射板16會將射入底面的光線反射回導光板15中,以增加光線的使用效率。由導光板15射出的光線在經由擴散片13的均光作用與稜鏡片12的集光作用以提高光線的亮度與均勻度後,接著再射入液晶面板11內,藉以使液晶面板11顯示影像。此外,外框17係用來包覆及保護上述零件。Please refer to FIG. 1 . FIG. 1 is a schematic structural view of a backlight module 10 and a liquid crystal panel 11 . The backlight module 10 is mainly composed of a light source (for example, a cold cathode fluorescent tube, a hot cathode fluorescent tube, a light emitting diode) 14, a reflector (reflector) 16, a light guide plate (15), and a diffusion. A sheet of a diffusion sheet 13, a brightness enhancement film 12, and an outer frame 17 are assembled. The light source 14 is generally a cold cathode ray tube. After the light emitted from the light source 14 enters the light guide plate 15, the incident light is guided to distribute it into a uniform surface light source, and the reflector 16 reflects the light incident on the bottom surface. It is returned to the light guide plate 15 to increase the efficiency of use of light. The light emitted from the light guide plate 15 enhances the brightness and uniformity of the light by the light collecting action of the diffuser 13 and the light collecting action of the cymbal 12, and then enters the liquid crystal panel 11 to cause the liquid crystal panel 11 to display an image. . In addition, the outer frame 17 is used to cover and protect the above parts.
請參閱第2圖。第2圖係為習知一背光模組20之部份示意圖。背光模組20之一燈源線23係由背光模組20的背面出線並固定,其固定方式通常是使用背光模組20之一外框21延伸而成的一卡勾22以固定之。然而,由第2圖可知,若卡勾22太靠近背光模組20之邊緣,則會導致燈源線23偏出背光模組20之外側。如此一來,在接下來的組裝過程中,外露的燈源線23就會很容易被顯示器內部之金屬件刮傷,進而影響顯示器之運作,甚至會出現內部電路短路之問題。Please refer to Figure 2. FIG. 2 is a partial schematic view of a conventional backlight module 20. A light source line 23 of the backlight module 20 is lined and fixed by the back surface of the backlight module 20, and is usually fixed by using a hook 22 extending from the outer frame 21 of the backlight module 20. However, as can be seen from FIG. 2, if the hook 22 is too close to the edge of the backlight module 20, the light source line 23 is biased out of the outer side of the backlight module 20. In this way, in the subsequent assembly process, the exposed light source line 23 is easily scratched by the metal parts inside the display, thereby affecting the operation of the display, and even the internal circuit short circuit.
請參閱第3圖,第3圖係為另一習知背光模組30之部份示意圖。由第3圖可知,若背光模組30內之一擋板31與一卡勾33之間的間隙過大,則會出現對穿過其間的一燈源線34夾持力不足的問題,只要稍微的外力拉扯就容易使燈源線34從擋板31與卡勾33之夾持中脫離。若擋板31與卡勾33之間的間隙過小,則容易出現燈源線34之外緣包覆被刮傷的問題。所以不管是如第2圖或第3圖所示之固定燈源線的方式都在使用上有些限制或缺陷。Please refer to FIG. 3 , which is a partial schematic view of another conventional backlight module 30 . As can be seen from FIG. 3, if the gap between one of the baffle 31 and the one of the hooks 33 in the backlight module 30 is too large, there is a problem that the clamping force of a light source line 34 passing therethrough is insufficient, as long as it is slightly The external force pull easily disengages the light source wire 34 from the clamping of the shutter 31 and the hook 33. If the gap between the shutter 31 and the hook 33 is too small, the problem that the outer edge of the light source wire 34 is scratched is liable to occur. Therefore, the method of fixing the light source line as shown in Fig. 2 or Fig. 3 has some limitations or defects in use.
請參閱第4圖,第4圖係為另一習知背光模組40之爆炸圖。由第4圖可知,背光模組40中之固定蓋41係僅以扣合之方式連接於基板42上,也就是說,固定蓋41與基板42係為可分離之元件,因此在維修時,固定蓋41往往會從基板42上拆卸下來以利後續之維修,等到維修完畢後,再把固定蓋41裝回基板42上,如此一來,不僅會造成維修上的不便,更容易會因一時的疏忽而造成固定蓋41之遺失。此外,固定蓋41與基板42係僅以扣合之方式連接,故容易形成間隙空間,進而在如第4圖所示之開孔32處產生漏光的現象而減損液晶面板的亮度。Please refer to FIG. 4, which is an exploded view of another conventional backlight module 40. As can be seen from FIG. 4, the fixing cover 41 of the backlight module 40 is connected to the substrate 42 only by snapping, that is, the fixing cover 41 and the substrate 42 are separable components, so that during maintenance, The fixing cover 41 is often detached from the substrate 42 for subsequent maintenance, and after the repair is completed, the fixing cover 41 is returned to the substrate 42. This not only causes inconvenience in maintenance, but also tends to cause temporary damage. The negligence caused the loss of the fixed cover 41. Further, since the fixing cover 41 and the substrate 42 are connected only by the fastening, the gap space is easily formed, and light leakage occurs in the opening 32 as shown in FIG. 4, thereby reducing the brightness of the liquid crystal panel.

The rotating shaft 810 of the cover 808 drives the holding portion 816 with the rotating shaft 810 of the first substrate 802 as a fulcrum and rotates away from the second substrate 804, so that the cable 806 can be removed, but the clamping mechanism of the fixing cover 808 The 818 is still clamped on the rotating shaft 810 of the first substrate 802, so that the complicated removal process caused by the prior art that the fixed cover and the substrate are separable components and the problem that the fixed cover is often lost due to temporary loss can be avoided.
值得一提的是,扣勾814之位置可不受上述之限制,也就是說,扣勾814亦可因應設計上之需求以及纜線806之位置而改設於板體812之其他位置。此外,固定蓋之卡勾與扣勾之嵌合可不限於上述之數量,舉例來說,如第10圖所示,固定蓋808可另包含一第二延伸部824以及一第二卡勾826。第二延伸部824延伸自護持部816之第二側821,而第二卡勾826延伸自第二延伸部824,第二卡勾826係用來卡合第二基板804之扣勾814,第一延伸部820與第二延伸部824係分別設於扣勾814之相反兩側,如此固定蓋808即可藉由第一卡勾822以及第二卡勾826分別與扣勾814之扣合,進而更為穩固地連接於第二基板804上。It is worth mentioning that the position of the buckle 814 is not limited by the above, that is, the buckle 814 can be changed to other positions of the board 812 according to the design requirements and the position of the cable 806. In addition, the fitting of the hook and the hook of the fixing cover is not limited to the above-mentioned number. For example, as shown in FIG. 10, the fixing cover 808 may further include a second extending portion 824 and a second hook 826. The second extension 824 extends from the second side 821 of the retaining portion 816, and the second hook 826 extends from the second extension 824. The second hook 826 is used to engage the buckle 814 of the second substrate 804. An extension portion 820 and a second extension portion 824 are respectively disposed on opposite sides of the buckle 814. Thus, the fixing cover 808 can be respectively engaged with the buckle 814 by the first hook 822 and the second hook 826. Furthermore, it is more firmly connected to the second substrate 804.

Schematic diagram of the section. The backlight module 1100 includes a first substrate 1112 (such as a frame), a second substrate 1114 (such as a back plate), a cable 1110, and a fixed cover 1108. The first substrate 1112 has a fitting portion 1104. The second substrate 1114 has a plate body 1102 and a hook 1207. The buckle 1207 protrudes from the plate body 1102. The cable 1110 is held by the fixing cover 1108 on the second substrate 1114 and coupled to the light source. Next, please refer to Fig. 13, which is an enlarged schematic view of the fixed cover 1108 of Fig. 11. The fixing cover 1108 includes a holding portion 1208, a sliding groove 1302, a hook 1201, and a light shielding plane 1106. The holding portion 1208 is used to form a receiving space for accommodating the cable 1110 together with the second substrate 1114. Next, please refer to FIG. 14 at the same time. FIG. 14 is an enlarged schematic view of the fitting portion 1104 of FIG. The slot 1302 extends from a first side 1204 of the retaining portion 1208 for engaging a recess 1404 in the mating portion 1104 of the first substrate 1112. The hook 1201 extends from the first side 1204 of the retaining portion 1208 for engaging a raised structure 1402 of the mating portion 1104. The light shielding plane 1106 is disposed on one of the second sides 1202 of the holding portion 1108.
於此針對固定蓋1108之機構進行詳細之說明。請同時參閱第11圖、第12圖、第13圖以及第14圖。為了使固定纜線1110之固定蓋1108在維修過程中無需脫離第二基板1114,使用者可將位於固定蓋1118之第二側1202上的遮光平面1106卡合於第二基板1114上之扣勾1207,於此同時,位於固定蓋1108之第一側1204上的滑槽1302即可滑進第一基板1112之嵌合部1104,而延伸自護持部1208之第一側1204的卡勾1201則是扣合於嵌合部1104之凸起結構1402上,如此一來,固定蓋1108係可藉由遮光平面1106與扣勾1207之卡合、滑槽1302與凹槽1404之卡合,以及卡勾1201與凸起結構1402之扣合而固定於第一基板1112與第二基板1114上,因此,如第12圖所示,纜線1110即可藉由固定蓋1108之護持部1208以及第二基板1114所共同形成之容置空間,而得到進一步的固定與保護。此外,由第12圖可知,當固定蓋1108固定於第二基板1114時,固定蓋1108之遮光平面1106係可遮住第二基板1114之開孔1203,故可防止位於第二基板1114下方之燈源從開孔1203射出光線。The mechanism for fixing the cover 1108 will be described in detail herein. Please also refer to Figure 11, Figure 12, Figure 13, and Figure 14. In order to prevent the fixing cover 1108 of the fixing cable 1110 from being detached from the second substrate 1114 during the maintenance process, the user can engage the light shielding plane 1106 located on the second side 1202 of the fixing cover 1118 on the second substrate 1114. 1207, at the same time, the sliding slot 1302 on the first side 1204 of the fixed cover 1108 can slide into the fitting portion 1104 of the first substrate 1112, and the hook 1201 extending from the first side 1204 of the holding portion 1208 The fixing cover 1108 is fastened by the engagement of the light-shielding plane 1106 with the buckle 1207, the engagement of the sliding groove 1302 with the groove 1404, and the card. The hook 1201 is fastened to the first substrate 1112 and the second substrate 1114 by the fastening of the protruding structure 1402. Therefore, as shown in FIG. 12, the cable 1110 can be secured by the holding portion 1208 of the cover 1108 and the second The accommodating space formed by the substrate 1114 is further fixed and protected. In addition, as shown in FIG. 12, when the fixing cover 1108 is fixed to the second substrate 1114, the shielding plane 1106 of the fixing cover 1108 can cover the opening 1203 of the second substrate 1114, thereby preventing the underlying substrate 1114 from being located under the second substrate 1114. The light source emits light from the opening 1203.
除此之外,若想要卸除固定蓋1108分別與第一基板1112和第二基板1114之組裝,可朝第12圖所示之箭頭A方向對卡勾1201之突出部1205施力,藉以推動卡勾1201自第一基板1112之凸起結構1402上鬆脫,接下來再將固定蓋1118之滑槽1302順著嵌合部1104之凹槽1404滑出,直到遮光平面1106完全退出與扣勾1207之卡合為止,如此即可完成卸除固定蓋1108之程序。In addition, if the fixing cover 1108 is to be assembled with the first substrate 1112 and the second substrate 1114, respectively, the protruding portion 1205 of the hook 1201 can be biased in the direction of the arrow A shown in FIG. The push hook 1201 is released from the protruding structure 1402 of the first substrate 1112, and then the sliding groove 1302 of the fixing cover 1118 is slid out along the groove 1404 of the fitting portion 1104 until the light shielding plane 1106 is completely withdrawn and buckled. The hook 1207 is engaged until the fixed cover 1108 is removed.
值得注意的是,第三實施例固定蓋之機構不限上述之說明,舉例來說,請同時參閱第15圖以及第16圖,第15圖為本發明另一實施例固定蓋1500之放大示意圖,第16圖為對應第15圖固定蓋1500的嵌合部1600之放大示意圖。由第15圖可知,固定蓋1500具有一組卡勾1502,用來扣合如第16圖所示之凸起結構1602,然而,本發明之卡勾數量以及卡合方向可不受上述實施例之限制,意即固定蓋之卡勾數量可多於上述實施例之數量且卡勾方向亦可變更,如方向改為朝上,也就是說,卡勾方向、卡勾數量與凸起結構之位置端視實際需要調整。It should be noted that the mechanism for fixing the cover of the third embodiment is not limited to the above description. For example, please refer to FIG. 15 and FIG. 16 simultaneously. FIG. 15 is an enlarged schematic view of the fixing cover 1500 according to another embodiment of the present invention. Fig. 16 is an enlarged schematic view showing the fitting portion 1600 of the fixing cover 1500 corresponding to Fig. 15. As can be seen from Fig. 15, the fixing cover 1500 has a set of hooks 1502 for engaging the protruding structure 1602 as shown in Fig. 16. However, the number of hooks and the engaging direction of the present invention are not limited to the above embodiments. Restriction means that the number of hooks of the fixed cover can be more than the number of the above embodiments and the direction of the hook can be changed, for example, the direction is changed upwards, that is, the direction of the hook, the number of hooks and the position of the raised structure The actual needs need to be adjusted.
綜上所述,相較於習知技術之固定蓋僅以扣合之方式連接於基板上之機構設計,本發明係利用固定蓋之旋轉軸扣合於基板之扣勾上、或是利用固定蓋之夾持機構夾持住基板之旋轉軸之機構設計,或是利用固定蓋之卡勾扣合住基板之嵌合部之方式以達到將固定蓋固定於基板上之目的,如此一來,本發明不僅可簡化先前技術因固定蓋與基板係為可分離之元件所帶來的繁複拆除流程,並可避免因一時疏失而遺失固定蓋的問題。In summary, the fixed cover of the prior art is only designed to be fastened to the substrate by the fastening mechanism. The present invention is fastened to the buckle of the substrate by the rotating shaft of the fixed cover, or is fixed by using The clamping mechanism of the cover clamps the mechanism of the rotating shaft of the substrate, or the hook of the fixing cover is used to fix the fitting portion of the substrate to achieve the purpose of fixing the fixing cover to the substrate, so that The invention not only simplifies the complicated dismantling process brought about by the prior art that the fixed cover and the substrate are separable components, but also avoids the problem of losing the fixed cover due to temporary loss.
