200821704 九、發明說明： 【發明所屬之技術領域】 本發明係提供一種液晶顯示器(liquid crystal display，LCD)與 一種背光模組(backlight module，BLM)，尤指一種具有特別設計的 光源與組裝元件之液晶顯示器與背光模組。 【先前技術】 液晶顯示器不論在小尺寸或大尺寸的應用上，皆已蓬勃發 展’且由於液晶顯示器具有質量輕、體積薄、低耗能、無輻射還 有其他的優良特性，因而成為市場上的主流產品。因此，液晶顯 示為已廣泛應用於各種不同的資訊產品中，例如：筆記型電腦、 手機、數位相機或個人數位助理（PDA)，甚至逐漸取代傳統陰極 射線管（cathode ray tube，CRT)電視、背投影式電視或電漿 (plasma display panel，PDP )電視。 π由於液晶分子本身是不發光的’背光模組因而成為液晶顯示 器主要元件之一，而傳統的背光模組係利用冷陰極螢光燈管（cold cathode fluorescent lamp ’ CCFL)作為光源。第ι圖為習知背光模 組之部分剖面圖’此習知#紙组1G包含有—導歧14、一設置 於導光板14附近之冷陰極螢光燈管12、—設置於導光板下之反射 n、後數個設置於導光板14上之光學薄膜以及—用於固定 :細組10組件之框架2〇。由於冷陰極螢光燈管12會從燈管的 母-側產生光線’因此必須於冷陰極螢光燈管12旁置放—燈管反 5 200821704 射罩22，以將光線反射回冷陰極榮光燈管12或導光板14，因而 提升光_率。並且，為了敎光線從燈管反鮮22與光學薄膜 18間之上側空隙漏失，需設置—遮光料24以遮驗管反射罩 22與光學薄膜1 $之間的空隙。 然而’由於以冷陰極榮光燈管為光源之液晶顯示器限制了色 彩^格的改進，因此冷陰極螢絲管的规已漸漸地無法滿足客 戶而求’而且冷陰極螢光燈管本身含有汞，不符合作為綠色產品 的要求。因此，近幾年來，發光二極體（light emitting出〇如，led ) 已被應用背光模組上作為光源使用，因為發光二極體具有色彩飽 和度间、反應速率快與體積小等優勢，使得在小尺寸的液晶顯示 器中廣受歡迎。然而，由於白光發光二極體所發出飽和的白光技 術還尚未成热，所以在許多產品中係同時在背光模組中使用紅 光、綠光與藍光發光二極體作為絲。在此航下，為了能使紅 光綠光與監光光線充分混光，就必需有要良好的混光設計，所 以發光二極體式的背細組需要複_機械構造以及高於冷陰極 螢光燈管背光模組之價格。 美國專利第6,930,737號專利案與美國公開號第2〇〇5冶157521 號專利案已揭露習知以發光二極體作為光源之液晶顯示器結 構。根據美國專利第6,930,737號專利案與參考第2圖，其揭露一 液_顯不器裝置5〇包含有一外框52、一框架72、一液晶面板％、 數片光學薄膜56、一光導管（喻Pipe，或稱導光板）60、增強 200821704 型鏡面反射片（enhanced specular reflector，ESR ) 70、一印刷電路 板（print circuit board，PCB) 62、發光二極體陣列 64、66、一增 強型擴散反射片（enhanced diffuser reflector) 68、一發光二極體控 制電路（圖未示）以及一電路板（圖未示）。液晶顯示器裝置50 之背光模組58係由容納於框架72中之光學薄膜56、光導管60、 增強型鏡面反射片70、印刷電路板62、發光二極體陣列64、66 以及增強型擴散反射片68所組成，並且框架72包含有一前框架 與一後框架用於固定背光模組58，其中發光二極體陣列64、66 係置放於为光模組58之兩側使得從發光二極體發出的光線能夠穿 透光導管60的側壁而進入光導管60。而且，為了避免漏光，必須 a又置增強型#兄面反射片70以將發光二極體陣列64、66固定在光 導管60附近，並且將具有大入射角的光線反射回光導管6〇，以提 升光利用率。由此可知，為了固定所有的絲元件與提供較佳的 成效，背光模組58係由許多的組褒零件所組成。因此，第2圖所 示之液晶顯示器裝置50或背光模組58的組裝程序是非常複雜且 耗時的。 —由此可知，對於業界來說’提供—具有良好效益的光源與一 簡單的構造以簡化組裝流程仍為—重要的課題。 【發明内容】 柄月之主要目的在於提供_種液晶顯示器與—種背光模 、、且，以解決上述習知之問題。 200821704 根據本發明之申請專利範圍，係揭露一種液晶顯示器，其包 含有一導光板、一液晶面板设於導光板之上、一具有一框架壁與 一用於置放導光板的隔間之框架以及一光條。該框架壁具有一開 口與一光條容置空間，而且該光條係插入光條容置空間。 從該光條被插入框架之光條容置空間可知，本發明提供了至 少四項優點：（1)降低成本：不再需要習知技術中額外的遮光膠 帶或燈管反射罩；（2)組裝容易：隨插即用的光條可以簡單的組 裝在框架上，因此可以節省人力；（3)節省空間設計：因為該光 條為埋在框架之框架壁内，可以提供窄小邊緣之液晶顯示器或背 光模組；以及（4)光利用率高：位於該光條上之光源與導光板兩 者係相貼並列而設於框架内，使得從光源射出之所有光線能夠直 接穿透進入導光板，而無光線漏失。 【實施方式】 第3圖為本發明第一實施例之一液晶顯示器1〇〇的剖面示意 圖’而第4圖係為第3圖所示之背光模組刚的示意圖。本發明 之液晶顯示器1()()包含有一液晶面板撤與一背光模組刚，硫 晶=板102與背光模、组1〇4 —起固定於外框1〇6内以構成液晶顯 Μ 100。背光模组104包含有一框架116具有框架壁收與一 隔間116b、_設置於關116b内之導光板m置於導絲 應下之反射片m以及一插入其中一框架壁_内且置放於導 200821704 光板108旁之光條114。 更進一步地說，框架116係為一體成型之結構，並且具有形 成隔間116b之四個框架壁116c與一固定帶116a，使導光板1〇8 與反射片122得以置放且固定於隔間116b内，並於固定帶ιι6& 上。並且，框架116係由具有高反射性之材料所組成，得以用來 反射光線，例如白色材料或淡色的塑膠材料。或者，框架116也 可用黑色材料來形成以避免漏光。此外，框架116中用來置放光 條114的框架壁116c具有一開口 ll6d，且在框架壁n6c上形成 一光條容置空間120，使得光條Π4可以經過開口 116(1插入光條 谷置空間120 ’而置放在導光板1〇8旁。光條114係為一隨插即用 (plug-and_play)之光條，其包含有一基板或一印刷電路板n〇與 複數個置於印刷電路板110上的光源或發光二極體112，而其中發 光一極體112較佳為白光側面型發光二極體者。 而設置於導光板108下之反射片122係用於將射出導光板1〇8 下表面的光線反射。另外，為了將光條114牢固地固定在框架壁 116c上舄要至少一螺絲124從框架116的底面透過螺絲孔來將 光條114固定在框架116上。除此之外，為了提供良好的平面光 源，背光模組104可以另在導光板1〇8上加入複數個光學薄膜 118 ’例如擴散片或稜鏡片，並且光學薄膜118可以設置於框架壁 116c旁或隔間i16b内。 9 200821704 明茶考第5與6圖以及第7a與7b圖。第5與6圖以及第7a 與7b圖分別為背光模組1〇4之放大圖與發光二極體112之指向特 性圖。光條114之一外側面115並沒有被框架壁n6c所遮蔽，也 就是說，光條114的外側係曝露於框架116中。由於光條114係 插入框架壁116c中並鄰近設有導光板觸之隔間n6b，發光二極 體丨12的發光面會相當接近導光板1〇8，使得從發光二極體112發 出來的光線得以直接穿透導光板應的側壁，而提供一平面光源。 另外’根據第7a與7b圖，不管是發光二極體112的χ軸或γ軸， 發射角大於80度之發光二極體112的相對發光強度幾乎為零，並 且發射角大於60度之發光二極體112的相對發光強度則小於5〇。 因此，應關本發明之側面型發光二極體112具有—散射角為約 ±80度，較佳為約±60度。這表示每個發光二極體112的總散射角 為120度，因此，由於發光二極體112為具有指向特性，所以在 習知技術中所使狀燈管反鮮對本發明已不再需要，而且當散 射角不大日彳’在傳統背光模組中額外的遮光膠帶可以被料，因 為由發光二極體112發射出之大角度光線非常少。而且，即使由 I光-極體112射出具有大肢散射肖之光線不會直接穿透進入 導光板觸，框架116 一樣可以阻擋光線，並避免光線射出背光模 組104。舉例來說，假如框架116係用白色材料所作成的，而行進 到舍光一極體112上方之框架116的域會被反射回導光板舰， 因而提升光利用率；另-方面，假如框架116係用黑色材料所製 成的，行進到發光二極體112 ±方之框架116的光線則會被框架 116吸收，因而避免漏光問題。蛾可知，本發明裝置並不需要額 200821704 •外麟f反射罩或遮光膠帶，而且組裝流程也可因此簡化，更可 以節省原料。 請參考第8與9圖。第8與9圖為背光模組刚的部份放大

光條114插入光條容置空間12〇後，導電墊128即會電性連接到 一導線（圖未示），導線可設置於框架116中或電性連接到一可撓 性印刷電路（圖未示）。 第ίο到14圖為本發明各種實施例之背光模組104的部份示 200821704 思圖’為了簡化說明，其中大部份元件與第3到9圖所示之元件 具有相同符號。請參考第10圖。第1〇圖為本發明之第二實施例。 框架116之框架壁ii6c具有一在框架壁n6c上形成絲容置空間 136之開口 ll6d，而開口 u6d包含有複數個窄部14〇與複數個寬 部138交錯排列。為了容納光條114，窄部14〇的高度h為接近或 稍U大於光條114之印刷電路板no的厚度，且寬部丨38的高度H 為接近或稍微大於印刷電路板11〇與一個發光二極體112的總厚 度。因此，當光條114插入光條容置空間136時，光條114會被 牛固地固疋住而不會水平橫移。此外，寬部138的寬度為接近或 稍微大於發光二極體112的寬度。 請參考第11圖。帛H目為本發明第三實施例之背光模組1〇4 之框术116與光條148的示意圖。在此實施例中，隨插即用之光 條148包含有一印刷電路板144與複數個置於印刷電路板144上 之發光二極體146，其中印刷電路板Μ4具有至少一寬面14如平 行於設置在隔間ll6b中之導光板與至少一窄面14牝平行於框架 壁116c。值得注意的是，發光二極體146係置放於窄面14仆上， 所以光條148之總厚度比前述之貫施例較小。因此，位於框架壁 上之開口 142的面度可以比較小，差不多與印刷電路板144 之厚度相同，也就是說，開口 142的高度等於或大於絲148之 厚度。 第12與13圖為本發明第四實施例之背光模組1〇4之框架116 12 200821704 •

日守’無發光二極體置放之寬面施係平行於框架壁·，並且光 條谷置空間154之高度幾乎與印刷電路板15()之寬面15Qa的寬度 相同。並且，為了將光條156固定於光條容置空間154内，可用 數個乍膠V 160或-個寬膠帶（圖未示）將印刷電路板15〇黏著 於框架壁116c上。 第14圖為本發明第五實關之背光模組之框架116與光條 U4的不意圖。在此實施例所使用之光條114係與本發明之第一實 加例中相同’其中光條114包含有—印刷電路板則、複數個側面 型發光二極體112、一螺絲孔或一定位孔126與一置放於印刷電路 板110上之導電墊128。值得注意的是，形成絲容置空間之框架 的開口 158為一方型開口。而開口 158的高度接近或稍微大於 印刷電路板110與一個發光二極體112的總厚度。 本發明之優勢在於隨插即狀光條係置放於光條容置空間 内，使得習知技術中之額外的遮光膠帶或燈管反射罩已不再需 要。再者，光源為-隨插即_式之光源並且f光模組之框架為 13 200821704 一體成型之結構。因此，可降低框架之原料，而且藉由將隨插即 用光條插入光條容置空間來組裝背光模組非常容易簡單，所以可 以節痛組裝为光模組之人力。另外，由於光條被插入框架之框架 壁中，整個背光模組因而可具有窄邊，用以置放光源。另一方面， 因為插入框架壁中之光條幾乎緊鄰著導光板設置，所以從光源出 來之光線可以直接穿透進入導光板而有較少的光線會漏失。 综而言之，相對於習知技術，本發明之液晶顯示器或背光模 組至少具有降低成本、組裝容易、節省空間與光線利用率高等優 點。因此，根據本發明可提供具有結構簡單與效益良好之液晶顯 示器與背光模組。 以上所述僅為本發明之較佳實施例，凡依本發明申請專利範

Description of the Invention: [Technical Field] The present invention provides a liquid crystal display (LCD) and a backlight module (BLM), especially a specially designed light source and assembly component. Liquid crystal display and backlight module. [Prior Art] Liquid crystal displays have flourished in small-sized or large-sized applications. And because liquid crystal displays have light weight, thin size, low power consumption, no radiation, and other excellent characteristics, they have become on the market. Mainstream products. Therefore, liquid crystal displays have been widely used in various information products, such as notebook computers, mobile phones, digital cameras or personal digital assistants (PDAs), and even gradually replace traditional cathode ray tube (CRT) televisions. Rear projection television or plasma display panel (PDP) television. π is one of the main components of the liquid crystal display because the liquid crystal molecules themselves are non-illuminating, and the conventional backlight module uses a cold cathode fluorescent lamp (CCFL) as a light source. FIG. 1 is a partial cross-sectional view of a conventional backlight module. The paper group 1G includes a guide 14 and a cold cathode fluorescent lamp 12 disposed near the light guide plate 14 and disposed under the light guide plate. The reflection n, the last several optical films disposed on the light guide plate 14 and the frame 2 for fixing: the assembly of the thin assembly 10. Since the cold cathode fluorescent lamp tube 12 will generate light from the mother side of the lamp tube, it must be placed next to the cold cathode fluorescent lamp tube 12 - the lamp tube reverse 5 200821704, the cover 22 to reflect the light back to the cold cathode glory The tube 12 or the light guide plate 14 thus increases the light rate. Further, in order to remove light from the upper side gap between the tube reticle 22 and the optical film 18, a light-shielding material 24 is provided to shield the gap between the tube reflector 22 and the optical film 1$. However, because the liquid crystal display with the cold cathode glory lamp as the light source limits the improvement of the color grid, the gauge of the cold cathode fluorescent tube has gradually failed to satisfy the customer's requirements and the cold cathode fluorescent tube itself contains mercury. Does not meet the requirements as a green product. Therefore, in recent years, light-emitting diodes (light emitting, such as led) have been used as light sources in backlight modules, because the light-emitting diodes have advantages such as color saturation, fast reaction rate and small volume. This makes it popular in small-sized liquid crystal displays. However, since the saturated white light technology emitted by the white light emitting diode has not yet become hot, in many products, red, green and blue light emitting diodes are simultaneously used as the wires in the backlight module. In this flight, in order to make the red light green light and the light of the light to be fully mixed, it is necessary to have a good light mixing design, so the light-emitting diode type back-end group needs a complex mechanical structure and higher than the cold cathode firefly. The price of the light tube backlight module. A liquid crystal display structure using a light-emitting diode as a light source has been disclosed in U.S. Patent No. 6,930,737 and U.S. Patent No. 2,515, the entire disclosure of which is incorporated herein by reference. According to U.S. Patent No. 6,930,737 and the reference to Fig. 2, it is disclosed that a liquid crystal display device 5 includes an outer frame 52, a frame 72, a liquid crystal panel %, a plurality of optical films 56, and a light guide ( Yupe, or light guide plate 60, enhanced 200821704 enhanced specular reflector (ESR) 70, a printed circuit board (PCB) 62, LED array 64, 66, an enhanced type An enhanced diffuser reflector 68, a light emitting diode control circuit (not shown), and a circuit board (not shown). The backlight module 58 of the liquid crystal display device 50 is composed of an optical film 56 housed in the frame 72, a light pipe 60, an enhanced specular reflection sheet 70, a printed circuit board 62, a light-emitting diode array 64, 66, and an enhanced diffusion reflection. The frame 68 is composed of a frame 68, and the frame 72 includes a front frame and a rear frame for fixing the backlight module 58, wherein the LED arrays 64 and 66 are placed on both sides of the optical module 58 so as to be from the light emitting diode The light emitted by the body can penetrate the sidewall of the light pipe 60 and enter the light pipe 60. Moreover, in order to avoid light leakage, it is necessary to augment the enhanced type #面面反射片 70 to fix the light emitting diode arrays 64, 66 in the vicinity of the light pipe 60, and to reflect light having a large incident angle back to the light pipe 6〇, To improve light utilization. It can be seen that in order to fix all of the wire elements and provide better results, the backlight module 58 is composed of a plurality of component parts. Therefore, the assembly procedure of the liquid crystal display device 50 or the backlight module 58 shown in Fig. 2 is very complicated and time consuming. - From this it can be seen that it is still an important issue for the industry to provide a light source with good benefits and a simple construction to simplify the assembly process. SUMMARY OF THE INVENTION The main purpose of the handle month is to provide a liquid crystal display and a backlight module, and to solve the above-mentioned problems. The invention relates to a liquid crystal display comprising a light guide plate, a liquid crystal panel disposed on the light guide plate, a frame having a frame wall and a compartment for placing the light guide plate, and A light bar. The frame wall has an opening and a light strip accommodating space, and the light strip is inserted into the light strip accommodating space. From the light strip accommodating space in which the light strip is inserted into the frame, the present invention provides at least four advantages: (1) cost reduction: no additional light shielding tape or lamp reflector is required in the prior art; (2) Easy to assemble: the plug-and-play light strip can be easily assembled on the frame, so it can save manpower; (3) Space-saving design: Because the light strip is buried in the frame wall of the frame, it can provide liquid crystal with narrow edges. a display or a backlight module; and (4) high light utilization: the light source and the light guide plate on the light strip are juxtaposed and arranged in the frame, so that all light emitted from the light source can directly penetrate into the guide Light board without loss of light. [Embodiment] Fig. 3 is a schematic cross-sectional view showing a first embodiment of a liquid crystal display device according to a first embodiment of the present invention, and Fig. 4 is a schematic view showing a backlight module shown in Fig. 3. The liquid crystal display 1()() of the present invention comprises a liquid crystal panel removed and a backlight module, and the sulfur crystal=plate 102 and the backlight module and the group 1〇4 are fixed in the outer frame 1〇6 to form a liquid crystal display. 100. The backlight module 104 includes a frame 116 having a frame wall and a compartment 116b, a light guide plate m disposed in the off 116b, and a reflective sheet m disposed under the guide wire, and inserted into one of the frame walls _ Light strip 114 next to light plate 108 of 200821704. Further, the frame 116 is an integrally formed structure, and has four frame walls 116c and a fixing band 116a forming the partition 116b, so that the light guide plate 1〇8 and the reflection sheet 122 are placed and fixed in the compartment. Inside the 116b, and on the fixed belt ιι6 & Also, the frame 116 is composed of a highly reflective material that can be used to reflect light, such as a white material or a light colored plastic material. Alternatively, the frame 116 can also be formed from a black material to avoid light leakage. In addition, the frame wall 116c of the frame 116 for arranging the light strip 114 has an opening ll6d, and a light strip accommodating space 120 is formed on the frame wall n6c, so that the light strip Π4 can pass through the opening 116 (1 inserted into the light strip valley The space 120' is placed beside the light guide plate 1 〇 8. The light strip 114 is a plug-and-play light strip, which comprises a substrate or a printed circuit board n 〇 and a plurality of placed The light source or the light emitting diode 112 on the printed circuit board 110, wherein the light emitting body 112 is preferably a white light side light emitting diode. The reflective film 122 disposed under the light guiding plate 108 is used for emitting the light guide. In addition, in order to securely fix the light bar 114 to the frame wall 116c, at least one screw 124 is passed through the screw hole from the bottom surface of the frame 116 to fix the light bar 114 to the frame 116. In addition, in order to provide a good planar light source, the backlight module 104 may further include a plurality of optical films 118' such as a diffusion sheet or a cymbal on the light guide plate 〇8, and the optical film 118 may be disposed beside the frame wall 116c. Or in the compartment i16b. 9 200821704 Fig. 5 and Fig. 6 and Fig. 7a and Fig. 7b, Fig. 5 and Fig. 6 and Fig. 7a and Fig. 7b are respectively an enlarged view of the backlight module 1〇4 and a directional characteristic diagram of the light emitting diode 112. One of the outer side faces 115 is not obscured by the frame wall n6c, that is, the outer side of the light bar 114 is exposed in the frame 116. Since the light bar 114 is inserted into the frame wall 116c and is adjacent to the light guide plate In the case of n6b, the light-emitting surface of the light-emitting diode 12 is relatively close to the light guide plate 1〇8, so that the light emitted from the light-emitting diode 112 can directly penetrate the side wall of the light guide plate to provide a planar light source. According to the figures 7a and 7b, regardless of the χ or γ axis of the illuminating diode 112, the relative illuminating intensity of the illuminating diode 112 having an emission angle greater than 80 degrees is almost zero, and the emitting dipole having an emission angle greater than 60 degrees The relative luminous intensity of the body 112 is less than 5 Å. Therefore, the side-type light-emitting diode 112 of the present invention has a scattering angle of about ±80 degrees, preferably about ±60 degrees. This means that each of the light-emitting diodes The total scattering angle of the body 112 is 120 degrees, and therefore, since the light emitting diode 112 has To the characteristics, so the conventional lamp in the conventional technology is no longer needed for the present invention, and when the scattering angle is not large, the additional light-shielding tape can be received in the conventional backlight module because The polar body 112 emits a very small amount of light at a large angle. Moreover, even if the light emitted by the I-light body 112 having the large-body scattering is not directly penetrated into the light guide plate, the frame 116 can block the light and avoid the light. The backlight module 104 is emitted. For example, if the frame 116 is made of a white material, the domain of the frame 116 that travels above the light-emitting body 112 is reflected back to the light guide ship, thereby improving light utilization; On the other hand, if the frame 116 is made of a black material, the light traveling to the frame 116 of the light-emitting diode 112 is absorbed by the frame 116, thereby avoiding light leakage problems. According to the moth, the device of the present invention does not require a 200821704 • outer lining f reflector or light-shielding tape, and the assembly process can be simplified, thereby saving material. Please refer to Figures 8 and 9. Figures 8 and 9 show a partial enlarged view of the backlight module. 8 is the back side of the backlight module 104, wherein the reflective sheet 122 is disposed in the compartment U6b of the frame 116. The screw 124 is used to fix the light bar 114 in the light strip accommodating space 120 and is fixed from the back surface through a screw hole in the frame 116. Further, it is to be noted that the opening ll6d includes two narrow portions 12a and a wide portion 120b between the narrow portions 120a. In order to accommodate the strip m, the narrowness i of the narrow portion i is close to or slightly larger than the printed circuit board η. The thickness of the wide portion 1 plus & is close to or slightly larger than the total thickness of the printed circuit board HQ and the light-emitting diode I]. On the other hand, Fig. 9 is the front side of the backlight module 1〇4. In various embodiments, the screw, the cymbal 132 can be fixed by the front surface of the moonlight module 1〇4 through the screw holes 13 of the frame us. Therefore, a screw hole I% can be provided on the printed circuit board 11A for setting the screw 132. In addition, since the light strip 114 is a plug-and-play light strip, it includes at least one conductive pad 128 disposed on the printed circuit board, so that when the light strip 114 is inserted into the light strip receiving space 12, the conductive pad 128 is electrically connected to a wire (not shown), and the wire can be disposed in the frame 116 or electrically connected to a flexible printed circuit (not shown). Figures ίο to 14 show a partial representation of a backlight module 104 in accordance with various embodiments of the present invention. 200821704 In order to simplify the description, most of the components have the same reference numerals as those of the components shown in Figures 3-9. Please refer to Figure 10. The first drawing is a second embodiment of the present invention. The frame wall ii6c of the frame 116 has an opening ll6d for forming a wire accommodating space 136 on the frame wall n6c, and the opening u6d includes a plurality of narrow portions 14A and a plurality of wide portions 138 staggered. In order to accommodate the light bar 114, the height h of the narrow portion 14A is close to or slightly U greater than the thickness of the printed circuit board no of the light bar 114, and the height H of the wide portion 丨38 is close to or slightly larger than the printed circuit board 11〇 and one The total thickness of the light emitting diode 112. Therefore, when the light bar 114 is inserted into the light strip accommodating space 136, the light strip 114 is solidly held by the cow without horizontally traversing. Further, the width of the wide portion 138 is close to or slightly larger than the width of the light emitting diode 112. Please refer to Figure 11.帛H is a schematic diagram of the frame 116 and the light bar 148 of the backlight module 1〇4 of the third embodiment of the present invention. In this embodiment, the plug-and-play light strip 148 includes a printed circuit board 144 and a plurality of light-emitting diodes 146 disposed on the printed circuit board 144, wherein the printed circuit board 4 has at least one wide face 14 such as parallel. The light guide plate disposed in the compartment ll6b is parallel to the frame wall 116c with at least one narrow surface 14A. It should be noted that the light-emitting diodes 146 are placed on the narrow surface 14 so that the total thickness of the light strips 148 is smaller than the aforementioned embodiment. Therefore, the face of the opening 142 on the frame wall can be relatively small, almost the same as the thickness of the printed circuit board 144, that is, the height of the opening 142 is equal to or greater than the thickness of the wire 148. 12 and 13 are views of a frame 116 12 200821704 of a backlight module 1 4 according to a fourth embodiment of the present invention. This embodiment utilizes a top type light emitting diode 152 to form a light strip 156. The plug-and-play light strip 1S6 & includes a printed circuit board 150 for accommodating the light-emitting diode 152, and the printed circuit board 15 has two wide faces and two narrow faces 150b. Since the light-emitting diode 152 is of a top type, the light-emitting diode 152 can be placed on the printed circuit board 15 to face a wide surface of the guide. Therefore, as shown in Fig. 13, when the light bar 156 is inserted into the wire accommodating space 154, the wide surface of the non-light-emitting diode is placed parallel to the frame wall, and the height of the light bar valley space 154 It is almost the same width as the wide face 15Qa of the printed circuit board 15(). Moreover, in order to fix the light bar 156 in the light strip accommodating space 154, the printed circuit board 15 can be adhered to the frame wall 116c by a plurality of silicones V 160 or a wide tape (not shown). Figure 14 is a schematic view of the frame 116 of the backlight module of the fifth embodiment of the present invention and the light strip U4. The light strip 114 used in this embodiment is the same as in the first embodiment of the present invention, wherein the light strip 114 includes a printed circuit board, a plurality of side type light emitting diodes 112, a screw hole or a The positioning hole 126 and a conductive pad 128 placed on the printed circuit board 110. It is to be noted that the opening 158 forming the frame of the wire accommodating space is a one-piece opening. The height of the opening 158 is close to or slightly larger than the total thickness of the printed circuit board 110 and one of the light emitting diodes 112. An advantage of the present invention is that the plug-in strips are placed in the strip housing space, so that additional masking tape or tube reflectors of the prior art are no longer needed. Furthermore, the light source is a light source of the plug-in type and the frame of the f-light module is a monolithic structure of 13 200821704. Therefore, the material of the frame can be reduced, and it is very easy to assemble the backlight module by inserting the plug-and-play light strip into the light strip accommodating space, so that the labor of assembling the light module can be pain-relieved. In addition, since the light strip is inserted into the frame wall of the frame, the entire backlight module can thus have a narrow side for arranging the light source. On the other hand, since the light strip inserted into the wall of the frame is disposed almost adjacent to the light guide plate, the light from the light source can directly penetrate into the light guide plate and less light is lost. In summary, the liquid crystal display or the backlight module of the present invention has at least the advantages of cost reduction, ease of assembly, space saving, and high light utilization efficiency as compared with the prior art. Therefore, according to the present invention, a liquid crystal display and a backlight module having a simple structure and good efficiency can be provided. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should fall within the scope of the present invention.
