200914931 九、發明說明： 【發明所屬之技術領域】 本發明係關於-種背光模組及採用該f光模組之液晶 顯示裝置。 【先前技術】 由於液晶顯示裝置中液晶面板之液晶本身不發光，因 而為達到顯不效果，須給液晶顯示面板提供一面光源裝 置，如背光模組，以實現顯示功能。背光模組按結構分為 侧光式背光模組及直下式背光模組。 隨著液晶顯示器應用領域之不斷拓展，特別是大尺寸 液晶顯示器之應用，如液晶電視等，對液晶顯示器之背光 模組之出光輝度要求進—步提高，f要使用複數發光元件 以提高整個背光模組之出光輝度，傳統之側以背光模組 已不能滿足其出光輝度之要求，因此直下式背光模組成為 大尺寸液晶顯示器之主流。 請參閱圖1，係-種先前技術直下式背光模組之側面 示意圖。該直下式背光模組i包括一擴散板n、複數線光 源12及一反射板13。該反射板13為平板狀。該線光源η 設置在擴散板Π與反射板13之間，其為冷陰極螢光燈管。 該線光源12發出之光線直接或經反射板13反射後經由擴 散板1Π專輸至鄰近直下式背光模組i設置之液晶顯示面板 (圖未示），使液晶顯示面板獲得較佳輝度。 然而，當液晶顯不裝置的尺寸越大時，直下式背光模 組1中線光源12之尺寸亦會相對變大，導致在振動狀態下 200914931 線光源12之變形量相當大而容易斷裂。另外，由於線光源 ’ 12發熱，該直下式背光模組1内部之溫度亦相應上升，易 •使該擴散板11因表面受熱發生脫水現象而發生輕曲變 形’使直下式背光模組1的光學特性變差。 為解決上述問題，業界一般在擴散板及反射板之間增 加一支撐結構。請參閱圖2及圖3,圖2係另一種先前技 術直下式背光模組之側面示意圖，圖3係圖2所示直下式 为光模組之支樓件之立體放大示意圖。該直下式背光模組 2包括一擴散板21、複數線光源22、一反射板23、複數支 撐件24及一金屬背板25。該金屬背板25收容該擴散板 21、該複數線光源22 '該反射板23及該複數支撐件％。 該支撐件24夾於反射板23與擴散板21之間，該線光源 22之兩端另藉由燈管固持件（未標示）固持於該金屬背板％ 内，線光源22中部藉由支撐件24支撐以防止彎曲變形。 該支標件24包括-固定部（圖未示）、—支撐部—及 二支樓桿243。該支撐部242為—圓錐形柱體，其錐頂鱼 ‘該擴散板抵接，用於支撐該擴散板21。該固定部設置 於該支撐部242之底部，其可卡入反射片^及金屬背板 25相對應之收容槽（圖未示）内以固定該支撐# i 桿243由該支撐部242之錐體侧面橫向延伸 撐桿243上設置至少_ ± _ 丼又 支撐體246 ’用以支擇該線光源22 該固定部、支撐部242及支 民尤/原 叉捉杯243係一體成型社谨 惟’由於該支撐件24 # 一體成型社：構 24 -曰成型後，係體纽、纟。構，則該支樓件 -成U其僅可用於少數幾種甚至單—尺寸之液晶 200914931 顳示裝置。其所支撐之線光源22之尺寸亦需相對固定，若 要支持其他尺寸之液晶顯示裝置，則要其他尺寸之支持件 24。綜上，該支撐件24及使用其之背光模組之通用性較低。 【發明内容】 _ 有鑑於此，提供-種通用十生較強之背光模組實為必要。 另，提供一種採用上述背光模組之液晶顯示裝置亦 必要。 ”” 七一種背光模組’其包括至少—燈管及至少—支禮件。 每-支撐件包括-固定部及支撐該燈管之至少—固持部， 制定部及固持部係可分離之單獨個體，並可以組合成為 體。 —一種背光模組，其包括至少一燈管及至少一支撐件。 每一支撐#包括-固定部及支禮㈣管之至少 部’該固持部係卡入該固定部内以固定。 、 -種液晶顯示裝置’其包括一液晶顯示面板及 面板提供平面光之背光模組。該背光模組包t ‘該二支撐件。每一支撐件包括-固定部及支 單獨〆二，固持部，該固定部及固持部係可分離之 平倜们體並可以組合成為一體。 液晶顯干面：：：裝置，其包括-液晶顯示面板及~為該 少-平面光之背光模組。該背光模組包括至 撐該燈管之至二。每一支撐件包括-固定部及支 固定。 ^目持部，5㈣持部係卡人該固定部内以 200914931 、相較於先前技術，本發明之固定部及固持部採用組合 方式固定，上述部份可分離開來，單獨更換，共用性"。 【實施方式】 -請參閱圖4,係本發明背光模組第一實施方式之側面 不意圖。該背光模組3包括一擴散板31、複數線光源％、 一反射板33、複數支撐件34及一金屬背板％。該金屬背 板35收容該擴散板31、該複數線光源％、該反射板％、 =數牛％該支樓件％夹於反射板33與擴散板31 之間。該線光源32之兩端藉由燈管固持件（未標示）固持於 該金屬背板35内，其中部藉由支擇件別支撐以防止彎曲 線光源32為冷陰極螢紐管，該反射板％為平 請參閲圖5，係圖4戶斤+ * > /生。」 所不支撐件34之立體分解示意 ^ M6 〇 ^ 34包括—底盤342、一支撐部344及二固持 樓1 344為一圓錐體結構，其錐頂與該擴散板31 幸工微抵接以支撐·兮k 2 牙該擴政板31，其錐底設置有τ型卡塊 亥卡塊343上設置凸點（圖未示）。 347 =部Μ包括一固持臂347及設置於該固持臂 上之至>、一支撐體348，該支撐體348 32之中部，兮旧社辟m 入货成琢尤你 ^寺I 3 7之端部亦設置有卡塊345，且卡 塊345之—側包括凸點340。 頂部d f A料—83柱體結構，其包括相對設置之 °不不、底部（未標示）及位於該頂部及底部間之側面 200914931 〈未標示）’该頂部包括與支樓部344之卡塊343相匹配之 倒立T形卡槽341，其側面之相對兩側亦分別設置有與二 固持部346之卡塊345相匹配之侧立τ形卡槽341，該卡 槽341對應凸點340位置設置有與之相匹配之凹槽（圖未 示）。 明一併參閱圖6及圖7，係圖5所示支撐件34組裝後 之立體示意圖，圖7係圖6所示支撐件34之側示圖。組裝 時，將該支撐部344之卡塊343***該底盤342之頂部之 卡槽341内，並推動該卡塊343直至該卡塊343上之凸點 340嵌入該卡槽341之凹槽為止；分別將二固持部別^之 卡塊345***該底盤342之侧面之相對兩側之卡槽gw 内，並推動該卡塊345直至該卡塊345上之凸點Mi嵌入 =卡槽341之凹槽為止，該支撑们41裝完成。將該支撐 件34之絲342貼在反射上，即可起到支撐作用。 346=先前技術，該支撐件34之支撐部344、固持部 4係卡合固定於該底盤342上，即，該支標件Μ之各植 件均可拆開、分離。因此，對應不同尺寸之液晶顧晉 可分別根據線光源32之尺寸救 、裝置 進行更換；或者根據線光源3 2早之獨數调二固二臂3:7之尺寸， 一固持臂以支# 、而要單獨更換另 寸不同所導致之擴散板31 * )因“拉組尺 支撐部⑽之尺寸進行單獨更，對 之部份元件即可適應不同尺寸需求之 / 、支撐件34 低之成本下獲得較高之通用性。 &組’其可在較 10 200914931 實=併參閱圖9及圖1〇，圖9係本發明背光模組第二 件二Ϊ之概構分解示意圖，圖1〇係圖9所示之支撐 光H2立體7F意圖。該#光模組與第—實施方式之背 之二劈Γ ’其主要區別在於，支撐件44之固持部446 栌449 、，47上包括—滑槽449’支標體448可卡入該滑 :門之距:於該滑槽449内滑動，由此調整二支標體448 之間=距離，從而調整二線光源之間之距離。 曰顯:月圖11 ’係本發明液晶顯示裝置之示意圖。該液 二裝置5包括前述背光模組3及鄰近該背光模組3之 〜反59。該背光模組3還可替換為上述背光模組4。 抽’本發明並不限於上述實施方式所述，例如 狀可根據需求變更設計，僅需卡塊與卡槽可卡 "V ° ’該支擔部之形狀結構亦可根據需求變更設 ^需可其到支撐作料可；該底盤之底部可設置卡勾， 2由卡勾固定於反射片、金屬背板上’而非貼在反射片 亦可採用其他固定方式將底盤即固定部固定於反射 =、金屬背板上；該固持部亦可僅為一個，位於該支樓部 側，該支撐件之各個組成部份係分離之翠獨個 體，僅品可以組合成為一體即可，並非僅為卡合方式。 提中述，本發明確已符合發明專利之要件，爰依法 ^出專利申請。惟’以上所述者僅為本發明之較佳實施方 ;=發明之範圍並不以上述實施方式為限，舉凡熟悉本 =處4ί人士k依本發明之精神所作之等效修飾或變化， 白應涵蓋於以下申請專利範圍内。 11 200914931 【圖式簡單說明】 圖1係一種先前技術之直下式背光模組示意圖。 圖2係另一種先前技術之直下式背光模組示意圖。 圖3係圖2所示之背光模組之支樓件之立體示意圖。 圖4係本發明背光模組第一實施方式之示意圖。 圖5係圖4所示之背光模組之支撐件之立體分解圖。 圖6係圖5所示之支撐件组裝後之立體示意圖。 圖7係圖6所示之支撐件之側示圖。 圖8係固持不同數量之線光源之支撑件之示意圖。 圖9係本發明背光模組第二實施方式之部分結構示意圖 圖係圖9所示之支撐件組裝後之立體示意圖。 圖11係本發明之液晶顯示裝置之示意圖。 【主要元件符號說明】 3 擴散板 31 32 反射板 33 34 - 44 金屬背板 35 340 卡槽 341 342 卡塊 343、 345 344 固持部 346、 446 347 、 447 支撐體 348、 448 449 液晶面板 59 月光模組 線光源 支撑件 凸點 底盤 支撐部 固持臂 滑槽 12200914931 IX. Description of the Invention: [Technical Field] The present invention relates to a backlight module and a liquid crystal display device using the same. [Prior Art] Since the liquid crystal of the liquid crystal panel in the liquid crystal display device does not emit light itself, in order to achieve a remarkable effect, a liquid crystal device such as a backlight module must be provided to the liquid crystal display panel to realize the display function. The backlight module is divided into an edge-lit backlight module and a direct-lit backlight module according to the structure. With the continuous expansion of the application field of liquid crystal displays, especially the application of large-size liquid crystal displays, such as LCD TVs, the brightness of the backlight module of the liquid crystal display needs to be improved step by step, and the use of a plurality of light-emitting elements to improve the entire backlight The brightness of the module, the traditional side backlight module can not meet the requirements of its light brightness, so the direct backlight module becomes the mainstream of large-size liquid crystal display. Please refer to FIG. 1 , which is a side view of a prior art direct type backlight module. The direct type backlight module i includes a diffusion plate n, a plurality of line light sources 12, and a reflection plate 13. The reflector 13 has a flat shape. The line source η is disposed between the diffusion plate Π and the reflection plate 13, which is a cold cathode fluorescent lamp. The light emitted by the line source 12 is directly reflected by the reflector 13 and then transmitted to the liquid crystal display panel (not shown) disposed adjacent to the direct type backlight module i via the diffusion plate 1 to obtain a better brightness of the liquid crystal display panel. However, when the size of the liquid crystal display device is larger, the size of the line light source 12 in the direct type backlight module 1 is also relatively large, resulting in a relatively large amount of deformation of the line source 12 in the vibration state of 200914931, which is easily broken. In addition, since the temperature of the line light source '12 is increased, the temperature inside the direct type backlight module 1 is also increased accordingly, and the diffusion plate 11 is deformed by the dehydration of the surface due to heat, so that the direct type backlight module 1 is The optical characteristics are deteriorated. In order to solve the above problems, the industry generally adds a support structure between the diffusion plate and the reflection plate. Referring to FIG. 2 and FIG. 3, FIG. 2 is a schematic side view of another prior art direct type backlight module, and FIG. 3 is a perspective enlarged view of the straight type of the light module. The direct type backlight module 2 includes a diffusion plate 21, a plurality of line light sources 22, a reflection plate 23, a plurality of support members 24, and a metal back plate 25. The metal backing plate 25 houses the diffusing plate 21, the plurality of linear light sources 22' the reflecting plate 23, and the plurality of supporting members. The support member 24 is sandwiched between the reflector 23 and the diffuser 21. The two ends of the line 22 are held in the metal backplane by a lamp holder (not shown). The piece 24 is supported to prevent bending deformation. The support member 24 includes a fixing portion (not shown), a support portion, and two floor bars 243. The support portion 242 is a conical cylinder whose conical top fish abuts the diffusion plate for supporting the diffusion plate 21. The fixing portion is disposed at the bottom of the supporting portion 242, and can be inserted into the corresponding receiving slot (not shown) of the reflective sheet and the metal backing plate 25 to fix the support # i rod 243 from the cone of the supporting portion 242 The body side laterally extending strut 243 is provided with at least _± _ 丼 and the supporting body 246' for determining the line light source 22, the fixing portion, the supporting portion 242, and the supporting yuyu/original catching cup 243 are integrally formed. 'Because the support member 24 # integral molding company: the structure 24 - 曰 after molding, the system body, 纟. The structure, the building piece - can only be used for a few or even single-size LCD 200914931 display device. The size of the line source 22 supported by it is also relatively fixed. To support other sizes of liquid crystal display devices, support members of other sizes are required. In summary, the support member 24 and the backlight module using the same have lower versatility. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a backlight module with a strong universal life.
