201030424 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種顯示裝置、背光模組及夾具。 【先前技術】 液晶顯不裝置主要係由 ~~液晶顯不面板以及 背光 模組組合而成。其中，液晶顯示面板主要係具有彩色滤光 基板、薄膜電晶體基板以及一爽設於兩基板間的液晶層。 由於液晶顯示面板本身不具發光特性，必須藉助背光模組 來達到顯示的功能，而背光模組之功能即在於供應充足的 亮度與分佈均勻的面光源，使液晶顯示面板能顯示影像。 背光模組依光源設置的位置可分為側置式背光模組 以及直下式背光模組。目前背光模組所使用之光源有冷陰 極螢光燈（CCFL )以及熱陰極螢光燈及發光二極體 (LED)，其中，大尺寸背光模組一般以冷陰極螢光燈當作 光源。由於冷陰極螢光燈具備管徑細、壽命長及發光效率 高等優點，為大尺寸背光模組最適合之光源，而小尺寸面 板則大多採用發光二極體作為光源。 請參考圖1所示，其為習知技術之顯示裝置1之一側 視圖，顯示裝置1包含一顯示模組A及一背光模組2，顯 示模組A例如為液晶顯示面板。背光模組2包含一光源21 及一背板22，光源21包含一電路板211及一發光二極體 212，光源21設置於背板22，並利用一螺絲23穿過背板 22以及光源21的電路板211，以將背板22與光源21固 201030424 定。發光二極體212所產生的熱能，係由電路板211傳遞 至背板22,以免發光二極體212過熱，影響產品的可靠性。 其中，電路板211與背板22之間還可以有散熱膠或散熱 塾（圖中未顯不）’以協助熱能的傳遞。 但由於背板22及電路板211上的螺孔於形成時均會 產生公差，因此螺合時不但需要較長的時間，甚至會因為 組裝公差較大而無法螺合。另外，亦有習知技術利用雙面 膠來黏合電路板211及背板22，但長時間使用之下容易造 成背板22與光源21分離，更嚴重的情況將會導致發光二 極體212無法有良好散熱的效果。 因此，如何提供一種顯示裝置、背光模組及夾具，能 夠將背板及光源穩固地固定，不會因為長時間使用而造成 分離，並可提高生產組裝之效率，正是當前的重要課題之 【發明内容】 有鑑於上述課題，本發明之目的為提供一種能夠將背 板及光源穩固地固定，且生產組裝時間較短，並提高生產 效率之顯示裝置、背光模組及夾具。 為達上述目的，本發明提供一種顯示裝置包含一顯示 模組及一背光模組。背光模組鄰設於顯示模組，背光模組 包含一背板、一光源及一夾具，光源設置於背板，夾具固 定光源於背板。 為達上述目的，本發明提供一種背光模組包含一背 4 201030424 ^、-光源及-夾具。光源設置於背板，夾具固定光源於 背板。 、 ^為達上述目的，本發明提供一種顯示裝置包含一顯示 模，、且及是光模組。背光模組鄰設於顯示模組，背光模組 • & 3 —月板'—光源及—夹具。光源設置於背板。夾具固 - $光源於背板。其卜夾具包含-第-臂及一第二臂:、第 二臂與第一臂連接，第二臂更具有一彎折部。 癱 '域上述目的，本發明提供一種夾具係應用於一背光 核組’月光杈組包含一背板及一光源，光源設置於背板， 夾具固定光源於背板，夾具包含一第—臂及一第二臂，第 一臂與第一臂連接，第二臂更具有一彎折部。 承上所述，因依本發明之顯示農置、背光模組及夹且 係利用央具將光源固定於背板，並藉由第二臂之f折部所 提供之彈力或夾持力，增加夹具之固定力。如此一來，光 源及背板就不會因為長時間的使用而造成分離，以確保發 ❹光兀件所產生的熱能可以順利傳導以提升產品的可^ 生除此之外，利用夾具將背板及光源固定所需要的組裝 時間較短，可提高生產效率。 【實施方式】 以下將參照相關圖式， 示裝置、背光模組及夾具， 照符號加以說明。 說明依本發明較佳實施例之顯 其中相同的元件將以相同的參 明麥照圖2所不，本發明實施例之顯示裝置3包含— 5 201030424 顯不模組A及-背光模組4，顯示模組A係包含一顯示面 板及-驅動電路板（圖中未顯示），顯示模组A接收背光 板組4發出的光線，以顯示晝面。本實施例中，顯示裝置 3係以一液晶顯示裝置為例。 月光模組4 口又置於顯不模組a之一側，背光模組*用 =應缺的亮度與分佈均勻的面光源至顯示模組A，於 此背光模組4係以一伽罟彳北μ w，丄 人 置式月先杈組為例，背光模組4包 3 —月板5、一光源6及一夾具7。 ^ 5之㈣—般可為金屬、合金或其他導熱的材質。 背板5,例如設置於背板5的側邊，並 -、月板5的主要表面呈％麿。氺 至少—發光元件62。其中’電板、^ 一電路板61及 件62。電路板61係用以驅動發光元 Γ5 62 及马一封裝好的發光二極體 件62 &勃曰件另外，光源6中發光元 仟62的數置也可因需求 可具有複數個發光元件62，二例中’光源6係 由電路板6!而傳遞至背板5。 料生的熱能可 夹具7固定背板5及光源6，丈 及一第-臂77 # ^ ^ 丈具7包含一第一臂71 弟一 # 72。其中，第二臂72 施例中，係以第—臂71與第、# 71連接’本實 夾具7則約呈枴杖形，而夹旦 體成型為例，而 塑膠。 、之材貝係為金屬、橡膠或 用沖折部-的形成可利 f ㈣而得，彎折部721因形變 6 201030424 皆可依據產品需求折部721之彎折方向或角度 ㈣係位於變更。本實施例中，彎折 -臂勾住皆!二 間部位’組裝時，只需將第 ，而第二臂72則利用彎折部721 If ϋ 住光源6的電路板6]即可 :U 721頂抵 度略大於第一臂71與第二臂72 '、二6=板5的厚 裝後彎折部721合且有一^ 間的最小距離，因此組 持力，藉由f折;;2==(簡稱彈力)或-夾 固定光源6^/ 爭力，俾使央具7穩固地 具主、方板5。如此一來’光源6及背板5就不合 因為長時間的使用而造成分離，以確保發光元件62戶= 生的熱能可闕利傳導以㈣產品的可靠性。 本實施财，背板5更可具有一固定部Η，固定部 ::一:槽、一開孔或—凹槽，爽具7之-端例如是第 一 ί 72的—端可以穿過開孔或開槽，或是抵接於凹槽， 4助夾具7定位’圖2中固定❹係以開孔為例。 睛參照圖3至圖6,以下將主要針對背光模組中背板 及夾具的變化態樣來說明，為了方便起見，圖中的部分元 件（例如導光板及光學膜片）係省略不顯示。 請參照圖3所示’本實施例之背光模組如與上述 例不同的是，背板5a係具有一固定部5u，固定部5&係 以開槽為例’夾具7a之一端係穿過固定部％，以協助夾 具几固定。本實施例中，可依光源6的長度或其他需求， 而增加夾具7a的數量，使失具％的數量為複數個。 夾具7a更包含一連結臂73a，係用以連接第一臂7^ 201030424 及第二臂72a，於此以連結臂73a呈平面狀為例。第二臂 72a之彎折部721a係朝背板元及電路板61 具％固定背板5a及光源6。 俾使火 另外第一摩72a可具有一結合部722a，結合部722a • 可例如為一凸起且位於第二臂72a的一端區域。組裝時， - 夾具7a可由固定部5U滑入，並利用結合部722a與背板 '卡合，而將第一臂71a跨設於背板5a，第二臂72a則位 φ 於光源6上’以使光源6固定於背板5a。當然，結合部722a 的數量及形狀均可有所變化。 請參照圖4所示，本實施例之背光模組扑與背光模 組4a不同之處在於：背板5係具有一固定部η，其固定 :ji係以開孔為例，夹具7b之第二臂7孔係具有二個結 5邛722b，§亥等結合部722b約呈倒勾狀且設置於第二臂 Mb之-端區域，該等結合部722b的倒勾為不同方向但位 於同一平面。組裝時’該等結合部722b係可利用其彈性 • 使得該等倒勾内縮後穿過固定部51而與背扳5扣合。 請參照圖5所示，本實施例之背光模組4c與背光模組 4a不同之處在於··夾具7c的第二臂7几包含一開口 ^3c， 使發光元件62所發出之光線通過。第二臂72c夾置於電路 板61 ’且該第第二臂72c的一端穿過背板兄之固定部 51a，並利用結合部722c而與背板兄的另一表面卡合。σ 明參舨圖6所示，本實施例之背光模組4d與背光模 組4c不同之處在於··背板5b可不具有固定部，夾具％ 之第一臂71d係跨設於背板5b，第二臂72d則直接夹置於 8 201030424 光源6之發光元件62上，其中第二臂72d更具有一開口 723d，使發光元件62所發出之光線通過，如此一來，夾 具7d即可固定光源6於背板5b，且不阻礙光線的分佈。 請參照圖7所示，本實施例之背光模組4e與背光模組 4d不同之處在於：第二臂72e具有一結合部722e，其結合 部722e係為翹曲狀，其結合部722e於第二臂72e之一端 並與背板5b抵接，結合部722e係與背板5b之一凸起部 52b抵接。 接著，請再參照圖2所示，本發明亦提供一種背光模 組4，其係包含一背板5、一光源6及一夹具7。光源6包 含一電路板61以及至少一發光元件62，發光元件62設置 於電路板61，而光源6設置於背板5。夾具7包含一第一 臂71及一第二臂72，第二臂72與第一臂71連接，並具 有一彎折部721，藉由彎折部721所提供之彈力或夾持力， 俾使夾具7固定光源6及背板5。其中，背板5、光源6 及夾具7與上述實施例之中，背板5、光源6及夾具7具 有相同的技術特徵，故於此不再贅述。 另外，本發明提供一種夾具7，係應用於一背光模組 4。夾具包含一第一臂71及一第二臂72,第二臂72與第 一臂71連接，並具有一彎折部721，藉由彎折部721所提 供之彈力或夾持力，俾使夾具7固定一光源6及一背板5。 其中，第一臂71及第二臂72與上述實施例之中，第一臂 71及一第二臂72具有相同的技術特徵，故於此不再贅述。 承上所述，因依本發明之顯示裝置、背光模組及夾具 9 201030424 係利用夾具將背板及光源固定，並藉由第二臂之彎折部所 提供之彈力或夾持力，增加夾具之固定力。如此—來，光 源及背板就不會因為長時間的使用而造成分離，以確保光 源所產生的熱能可以順利傳導以提昇產品的可靠性。除此 之外，利用夹具將背板及光源固定所需要的組裴時間較 短’可提南生產效率。 以上所述僅為舉例性，而非為限制性者。任何未脫離 本發明之精神與範嘴，而對其進行之等效修改或變更，均 應包含於後附之申請專利範圍中。 【圖式簡單說明】 圖1為習知顯示裝置之-側視圖； 圖2為本發明實施例之顯㈣置之-側視圖； 圖3為本發明之背光模組之一示意圖； 圖4為本發明之背光模組之另一示意圖； 圖5為本發明之背光模組之又一示意圖； =6為本發明之背光模組之再—示意圖；以及 圖7為本發明之背光模組之-示意圖。 【主要元件符號說明】 1 ' 3 :顯示裝置 4e :背光模組 2 、 4 、 4a 、 4b 、 4c 、 4d 21、6 :光源 211、61 ··電路板 10 201030424 212 :發光二極體 22、5、5a、5b :背板 23 :螺絲 51、51 a :固定部 52b :凸起部 62 :發光元件 7、7a、7b、7c、7d、7e :夾具 71、 71a、71b、71c、71d、71e:第一臂 72、 72a、72b、72c、72d、72e :第二臂 721、721a、721b、721c、721d、721e :彎折部 722a、722b、722c、722e :結合部 723c 、 723d 、 723e :開口 73a、73b、73c、73d、73e :連結臂 A :顯示模組 11201030424 VI. Description of the Invention: [Technical Field] The present invention relates to a display device, a backlight module, and a jig. [Prior Art] The liquid crystal display device is mainly composed of ~~ liquid crystal display panel and backlight module. The liquid crystal display panel mainly has a color filter substrate, a thin film transistor substrate, and a liquid crystal layer disposed between the two substrates. Since the liquid crystal display panel itself does not have the illuminating property, the backlight module must be used to achieve the display function, and the function of the backlight module is to supply a sufficient surface light source with uniform brightness and uniformity, so that the liquid crystal display panel can display images. The backlight module can be divided into a side-mounted backlight module and a direct-lit backlight module according to the position of the light source. At present, the light source used in the backlight module is a cold cathode fluorescent lamp (CCFL), a hot cathode fluorescent lamp and a light emitting diode (LED). Among them, a large-sized backlight module generally uses a cold cathode fluorescent lamp as a light source. Since the cold cathode fluorescent lamp has the advantages of thin diameter, long life and high luminous efficiency, it is the most suitable light source for the large-size backlight module, and the small-sized panel mostly uses the light-emitting diode as the light source. Referring to FIG. 1 , which is a side view of a display device 1 of the prior art, the display device 1 includes a display module A and a backlight module 2 , and the display module A is, for example, a liquid crystal display panel. The backlight module 2 includes a light source 21 and a back plate 22. The light source 21 includes a circuit board 211 and a light emitting diode 212. The light source 21 is disposed on the back plate 22 and passes through the back plate 22 and the light source 21 by using a screw 23. The circuit board 211 is used to fix the back plate 22 and the light source 21 to 201030424. The thermal energy generated by the LEDs 212 is transmitted from the circuit board 211 to the backplane 22 to prevent the LEDs 212 from overheating, which affects the reliability of the product. Wherein, between the circuit board 211 and the backboard 22, there may be a heat dissipating glue or a heat sink (not shown) to assist in the transfer of thermal energy. However, since the screw holes on the back plate 22 and the circuit board 211 are formed with tolerances, the screwing time requires not only a long time but also a screwing failure due to a large assembly tolerance. In addition, there is also a conventional technique for bonding the circuit board 211 and the back board 22 by using a double-sided tape. However, under long-term use, the back board 22 is easily separated from the light source 21. In a more serious situation, the LED 212 cannot be used. Has a good heat dissipation effect. Therefore, how to provide a display device, a backlight module and a clamp can firmly fix the back plate and the light source without separation due to long-term use, and can improve the efficiency of production and assembly, which is an important issue at present. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a display device, a backlight module, and a jig capable of stably fixing a back plate and a light source, and having a short production and assembly time and improving production efficiency.
