’其中背板210包含一光學膜置放部犯與一侧壁 214，並且背板210的材質可以是鋁或鋁合金，其具有質量 較輕的特性，可使顯示模組2〇〇符合現今的市場趨勢。另 外，在背板210之内部還包括設置有一光源2〇9，其可以 是CCFL等線光源或是LED等點光源。 膠框220包含一面板置放部222與一侧壁固定部 224’其中膠框220的面板置放部222配置於背板210的光 學膜置放部212的上方。另外，膠框220的側壁固定部224 φ 裝設於背板210的侧壁214上，並且與其面板置放部222 彎折或垂直連接。電路板230裝設於膠框220的側壁固定 部224上，而前框240則配置於電路板230與膠框220的 面板置放部222上，並且前框240的材質可以是金屬或是 塑膠。 此外，本實施例之顯示模組200可為液晶顯示模組， 其另包括一光學膜片組260、一顯示面板270以及一軟性 電路板280。光學膜片組260裝設於背板210的光學膜置 11 201020619 8 29309twf.doc/n 放部212上，且位於光學膜置放部212與膠框220之間， 其可以是棱鏡片、增光片、擴散片或其組合’以提供顯示 模組200較佳的均勻性或更高的亮度，進而使顯示模組2 〇 〇 具有更出色的顯示品質。 在本實施例中，顯示面板270係為一液晶顯示面板， 其裴設於膠框220的面板置放部222上’且位於面板置放 部222與前框240之間以用來顯示晝面。軟性電路板280 鲁 提供電路板230與顯示面板270之間的電性連接。然而， 即便上述之顯不面板270是以液晶顯不面板為例進行說 明’但任何具有本發明所屬技術領域之通常知識者，皆可 將液晶顯示面板替換為其他需要背光模組的顯示面板。另 外，上述之顯不模組也可以與電聚顯不模組、場發射顯示 模組、發光二極體顯示模組或真空螢光顯示模組等自發光 的顯示模組組合’以構成混合模式之顯示模組。 彈性卡榫250的材質可以選自由矽膠、橡膠以及導電 橡膠所組成的群組’彈性卡榫250的材質應為具有良好彈 • 性與抗衝擊特性的材質，以提供顯示模組200較隹的抗震 效果。如此一來，即便顯示模組2〇〇在搬運過程中受到晃 動，而使顯示面板270產生位移或變形，連接於電路板23〇 與顯示面板270之間的軟性電路板28〇，仍可藉由彈性 榫250的良好彈性而避免受損或被扯斷。同時，彈性 250亦可選擇軟質的材料’以達到在搬運過程中 的效果。其中’若在實際狀況上有電氣需求時，例如.二 加良好的接地功能時，彈性卡榫細也可使用導電橡膠。曰 29309twf.doc/n 201020619 5 此外彈性卡榫250也可以是一體成型，不須由多個零組 件組合而成，在製程上也較為省時省力。 在本實施例中，彈性卡榫250包含一底部252、—貫 穿部254以及一頂部256。底部252裝設於侧壁214上。' 貫穿部254依序貫穿側壁固定部224與電路板23〇，並且 頂部256與前框240接觸以提供緩衝震動的效果。此外， 藉由頂部256的配置，可使電路板230與前框240之間保 持一定的距離，以避免電路板230上的晶片232與前框24〇 • 接觸，進而可使電路板230具有較高的可靠度。 更進一步地說，貫穿部254的截面特徵尺寸W2小於 底部252的截面特徵尺寸Wl。此處所謂截面特徵尺寸w 可以是圓的直徑、三角形外接圓的直徑、四邊形外接圓的 直徑或是多邊形外接圓的直徑。在本實施例中，底部252 因具有較大的截面特徵尺寸Wl，因此在受到外界震動時， 較不易從膠框220中跳脫出來。此外，貫穿部254因具有 較小的截面特徵尺寸W2’所以在組裝時較容易穿設於膠框 ❿ 220中。 彈性卡榫250另包括與貫穿部254連接的一突出部 258，其位於膠框220與電路板230之間，其中突出部258 包含一第一部分258a與一第二部分258b。側壁固定部224 ^具有一第一凹陷部224a，其背向於側壁214，而上述的 突出部258的第一部分258a即鑲嵌於第—凹陷部22知 内，第二部分258b則與電路板230接觸。再者，第一部分 258a也可以是僅有部分鑲嵌於第一凹陷部22如内。此外， 13 e 29309twf.doc/n 第一部份258a的截面特徵尺寸界3大於第二部分25此的 截面特徵尺寸W4以及貫穿部254的截面特徵尺寸W2。藉 由將截面特徵尺寸W較大的第一部份258a鑲嵌於側壁固 定部224的設計，可使彈性卡榫25〇與侧壁214之間具有 較咼的穩定性。另外，還可使電路板23〇與膠框22〇保持 一定的距離以避免接觸或碰撞，並且可同時被緊密地卡固 於膠框220的側壁固定部224上。 在上述蚱實施例中，突出部258包含第一部分258a 響與第二部分2娜，側壁固定部224具有第一凹陷部224&， 且上述的突出部258的第一部分258a鑲嵌於第一凹陷部 224a内。然而，本發明不限於此，在本發明之另一實施例 中，側壁固疋部224可不設計有第一凹陷部22如，因此貫 穿部254的突出部258是與侧壁固定部224的表面接觸。 在本發明之又一實施例中，突出部258亦可僅包含第一部 分258a，而不設計有第二部分258b。 。 為了便於組裝，本實施例對彈性卡榫25〇的細部尺寸 • 作了更精密的設計，如下所述。彈性卡榫250的頂部256 更包含一基部256a、一漸縮部256b與一緩衝平面25^ , 其中基部256a與電路板230接觸。漸縮部25奶連接基部 256a與緩衝平面256c，且緩衝平面旅與前框24〇接觸。 更詳細地說’頂部256之各部位尺寸由大而小 為：基部256a的截面特徵尺寸％、漸縮部鳩的任 面特徵尺寸W6、緩衝平面256c的特徵尺寸W7。另外，= 部256a的截面特徵尺寸W5又大於貫穿部254的截面特& 14 29309twf.doc/n 201020619 ο 尺寸W2。由上述可知’基部25如具有較大的戴面特徵尺 寸W5 ’因此可緊密地抵靠電路板23〇，進而可提供電路板 230良好的固定效果。 圖2A為將彈性卡榫配置於電路板之前的示意圖，圖 2B為將彈性卡榫配置於電路板之後的示意圖。請參考圖 2A ’電路板230上可先預留數個貫穿孔hi、匕、^、h4以 作為可容置彈性卡榫250 (繪示於圖2B)的位置。接著， 請參考圖2B’將彈性卡榫250 —一塞入貫穿孔Whf 參 h4内。特別是，在本實施例中，塞入貫穿孔h!、h2的彈性 卡榫250是位於鄰近電路板230之長度較長的相對兩侧配 置’以提供電路板230較佳的固定效果。另外，塞入貫穿 孔h3、h的彈性卡榫250則是位於鄰近於電路板230的邊 緣234配置，以防止電路板230受到外力衝擊時，在邊緣 234產生翹曲或變形。然而，本發明並不限定貫穿孔以及 彈性卡榫的數量以及位置，設計者可以依據實際狀況改變 以因應不同的設計需求。 Φ 為了讓任何具有本發明所屬技術領域之通常知識者， 可依照本說明書據以實施，以下將詳細說明本實施例之顯 示模組200的組裝方法。 圖3A至圖3G依序為本發明一實施例之顯示模紐的 組裳流程示意圖。如圖3A所示，首先提供膝框220 ’其中 膠框220的侧壁固定部224具有一第一貫穿孔224c，再將 侧壁固定部224裝設於背板210的側壁214上。同時，將 光學膜片組260放置在背板210的光學膜置放部212上。 15 201020619 ---------8 29309twf.doc/i 接著如圖3B至圖3C所示，將彈性卡榫25〇的底部 252塞入第一貫穿孔224c中。由於彈性卡榫25〇具有良好 的彈性，所以底部252會因擠壓而產生形變。當外力足以 使形變的底部252穿出第一貫穿孔224c時，底部252的彈 性回復力會使其恢復為底部252原本的形狀，以與侧壁214 接觸並且抵靠住侧壁214。在本實施例中，在將彈性卡榫 250的底部252塞入第一貫穿孔224c之後，彈性卡榫25〇 的突出部258即可卡住第一貫穿孔224c，而停止此—塞入 攀 動作。 在另一實施例中，彈性卡榫250的底部252更可設計 為具有不同截面長度的上半部分252a與下半部分252b。 =裝時，可先將截面長度較長的下半部份252b塞入第一貫 穿孔224c，接著再將截面長度較短的上半部分252&塞入 第一貫穿孔224c。如此一來，底部252所需的變形程度較 小，可使組裝的過程更為順暢。 ^ ，後如圖3D所示，在彈性卡榫250的底部252塞入 φ 第貝牙孔224c後，提供電路板230，其中電路板230具 有第一貝穿孔230a。接著，如圖3E所示，將電路板230 裝設於侧壁固定部224上，並直接將彈性卡棒25〇的頂部 256基入第二貫穿孔23〇a，而形成如圖3G之結構。 此外，實務上的作法通常是利用手工具或機器手臂夾 持頂部256穿出第二貫穿孔23〇a，故彈性卡榫25〇會先有 一點拉伸變形，接著再恢復原形，如圖3F至圖3G所示， 但本發明並不以此為限。另—方面，若是將電路板23〇的 29309twf.doc/n 201020619 第二貫穿孔230a’對準彈性卡榫25㈣頂部祝壓入，亦 是另-種可行的方法。因此，在設計上，緩衝平面放 的特徵尺寸I可以小於貫穿部的截面特徵尺寸％ 以便於組裝。頂部256會因為外力而產生形變，並且於穿 出第二貫穿孔23Ga之後恢復。此時，電路板23〇即可 被基部256a與突出部258緊密地卡固於侧壁22〇上，而無 法輕易地移動。 … 最後，請參照圖1所示，將顯示面板270放置於膠框 220的面板放置部222上，並且使電路板23〇上的軟性電 路板280與顯示面板270連接，再將前框24〇配置於電路 板230與面板置放部222上，並且使彈性卡榫25〇的頂部 256接觸且頂住前框240，以固定顯示面板27〇。至此步驟 即兀成顯示模組200的組裝。詳細而言，頂部256是透過 緩衝平面256c抵靠住前框240，藉由這樣的配置方式，顯 示模組200可具有較佳的避震效果。 在前述說明中，彈性卡榫250與顯示模組200中之其 φ 他組件的結合方向，是先朝向膠框220的方向結合，再朝 向電路板230的方向結合，其又稱為前扣型組裝方式。不 過，本發明並不限定彈性卡榫250與顯示模組200中之其 他組件的結合方向。以下，將配合圖示舉例說明在另一實 施例中的彈性卡榫，其可具有不同的型態，並且可從別的 結合方向與顯示模組中之其他組件作結合，其又稱為後扣 型組裝方式。此外’為了方便說明，並使說明内容能更易 於被理解’下文採用相同的標號來表示類似的元件，並省 17 201020619δ 29309twfdoc/n 略重複的文字說明。 圖4為依照本發明另一實施例之顯示模組的示意圖。 請參考圖4 ’顯示模組300包括一彈性卡榫350，其中彈性 卡榫350包含一底部352、一貫穿部354以及一頂部356。 膠框220的侧壁固定部224具有一第二凹陷部224b，其面 向於側壁214，並且有部分的底部352鑲嵌於此第二凹陷 部224b内。 再者’彈性卡榫350的貫穿部354依序貫穿膠框220 ❹ 的側壁固定部224與電路板230，並且彈性卡榫350的頂 部356與前框240接觸。詳細地說，彈性卡榫35〇的頂部 356包含一基部356a、一漸縮部356b與一緩衝平面356c， 其中基部356a與電路板230接觸。 圖5A至圖5E依序為本發明另一實施例之顯示模組的 組裝流程示意圖。如圖5A所示，首先提供背板21〇與光 學膜片組260，此時在背板210的光學膜置放部212上已 經放置有光學膜片組260。接著提供膠框22〇，其中膠框 ❹ 22〇的侧壁固定部224具有一第三貫穿孔224d。然後先將 彈性卡榫350的底部352裝設於侧壁214上，接著將彈性 卡榫350的頂部356塞入第三貫穿孔224d，並且使底部352 的一部份鑲嵌於第二凹陷部224b内，以形成如圖5B之結 構。 由於彈性卡榫350具有良好的彈性，所以頂部356會 因擠壓而產生形變。當形變的頂部356穿出第三貫穿孔 224d後，頂部356的彈性回復力會使其恢復為頂部356原 18 201020619 29309twf.doc/n 本的形狀。此外，實務上的作法通常是利用手工呈 手臂夾持膠框220，並向頂部356移動，使购=出° 第三貫穿孔224d，故彈性卡榫35〇會有一點壓縮變形，但 本發明並不以此為限。因此，緩衝平面356c的特徵尺 七可以等於貫穿部354的截面特徵尺寸+以利於組裝。
