201003232 * 九、發明說明 、 【發明所屬之技術領域】 本發明是有關於一種背光模組及其應用，且特別是有關 於一種側邊入光式背光模組及其應用β 【先前技術】 請參照第1圖，其係繪示一般側邊入光式背光模組之剖 面示意圖。一般而言，側邊入光式背光模組1 〇〇主要包括背 Γ 板102、反射片104、導光板106、光學膜片組108、膠框 110以及至少一燈管組丨丨6，其中光學膜片組1 〇8係由數個 光學膜片120所構成’而燈管組116則由至少一燈管112 與燈管反射罩114所構成。目前，背板1〇2通常係由金屬板 片所構成，且包括有底板122與立設在底板122周緣的侧板 124。而燈管112通常係採用冷陰極燈管（CCFL)。燈管反射 罩114之剖面結構通常呈门字型，且由依序接合之上側板 128、外側板130與下側板126所構成’而燈管112則設置 Q 在燈管反射罩114之上側板128、外側板130與下側板126 所形成之凹槽空間中。 組裝此側邊入光式背光模組i 〇〇的架構時，先將燈管組 116設置在背板102之上表面上’且偏設在背板！ 〇2 一側之 側板124的内側面旁’並使燈管丨丨2面向側邊入光式背光模 組100的内部。再將反射片104設置在背板1〇2之上表面 上’其中反射片104之邊緣區域壓設在燈管反射罩114之下 ' 側板126的一部分上’而使燈管反射罩114之下側板126 * 的一部分位於反射片與背板1〇2之底板112之間。接下 201003232 • 來，將導光板106壓設在反射片104上，其中導光板1〇6 、 之邊緣區域夾设·在燈管反射罩114之上側板128與下側板 126之間。如此一來’燈管112便位於導光板1 〇6之侧面}丄8 與燈管反射罩114之上側板128、外側板130及下側板ι26 所圍設而成的空間中。接著’將光學膜片組1〇8疊設在導光 板1 06之上表面上。然後’將膠框1丨〇框設在背板丨〇2之侧 板124之外側，並壓設在燈管反射罩丨14之上側板128上與 光學膜片組108之邊緣部分上。 「 在現行的側邊入光式背光模組1 〇〇架構中，燈管組n6 係設置在背板10 2之側板12 4與膠框11 〇之内側，亦即燈管 組116係位於膠框11〇、背板1〇2與導光板所圍成之空 間中。因此’燈管反射罩114的内側空間較小，而不僅導致 燈管組116内燈管112與燈管112之間產生碰撞之機率較 高，燈管112與燈管反射罩114之間產生碰撞之機率也會較 高，更導致燈管112與導光板106之間產生碰撞的機率也較 高’這些碰撞均容易產生碰撞噪音或導致燈管斷裂問題。此 ) 外，當需拆卸燈管組116時，則需先拆卸膠框no、光學膜 片組108、導光板1〇6、以及反射片104等元件後，方可取 出燈管組11 6。因此，現行的側邊入光式背光模組丨〇〇架構 在組裝與拆卸上均相當不便利。 【發明内容】 因此，本發明之目的就是在提供一種側邊入光式背光模 組’其光源組在背光模組中屬不完全包覆之外露構件，故可 * 拉大光源組之光源與光源之間的距離，如此一來，可有效降 201003232 .低光源與光源之間因碰撞而產生噪音或光源斷裂之機率。 ' 本發明之另一目的是在提供一種側邊入光式背光模 、’且在不增加为光模組之尺寸下，其光源組中之光源與導光 板之間的距離可加以擴大’因此可降低因光源與導光板之間 發生碰撞而產生噪音或光源斷裂之可能性。 本發明之又一目的是在提供一種液晶顯示器，在不增加 背光模組之體積下，可將側邊入光式背光模組之光源組中的 光源與光源反射罩之間的距離加大，因此可避免因光源與光 ( 源反射罩之間發生碰撞而產生噪音或導致光源損壞。 本發明之再一目的是在提供一種液晶顯示器之組裝方 法，其光源組係採由背光模組外側組裝方式，因此可直接拆 除光源組，因而相較於傳統架構之液晶顯示器，本發明之架 構在組裝、拆卸與維修上均相當便利。 根據本發明之上述目的，提出一種側邊入光式背光模 組，至少包括：一背板具有相對之第一表面以及第二表面； 一導光板設置在背板之第一表面上；至少一光源鄰設於導光 ϋ

貼合在光源反射罩之内側面與膠框之外側面及背板之外側 面之間。 【實施方式】 本發明揭露一種側邊入光式背光模組及其應用與組裝 ( 方法。為了使本發明之敘述更加詳盡與完備，可參照下列描 述並配合第2A圖至第12圖之圖式。 請參照第2A圖與第2B圖，其係分別繪示依照本發明 第一較佳實施例的一種側邊入光式背光模組之立體示意圖 與剖面示意圖。在此示範實施例中，側邊入光式背光模組 200a主要包括背板202a、導光板206a、至少一光源組208 以及膠框230a，其中光源組208主要係由至少一光源210 以及光源反射罩2 12a所構成。光源2 1 0 —般可採用冷陰極 〇 燈管（CCFL)或發光二極體光條（LED Light Bar)。光源反射 罩212a將光源210朝外所發出之光反射回導光板206a。本 實施例之光源反射罩212a具有门字型剖面結構，且此光源 反射罩212a包括依序接合之側板224a、側板226a以及側 板228a，其中側板224a與側板228a彼此相對，且至少一 光源210設置在側板224a、側板226a與側板228a所形成 之空間中，如第2B圖所示。背板202a可由金屬板片或硬 ' 質塑膠板片所構成，且背板202a具有相對之表面214與 • 21 6，例如底面與上表面。 9 201003232 • 在本示範實施例中，背板202a之表面2 1 6的外周緣區 « 域壓設在光源反射罩212a之侧板224a上，而導光板206a 則疊設在背板202a之表面2 14上’且使光源210鄰設於導 光板206a之侧面2 1 8，其中光源210介於導光板206a之側 面218與光源反射罩212 a之側板22 6 a之間。側邊入光式背 光模組200a更可依實際產品設計需求，而選擇性地在導光 板206a之下表面與背板202a之表面216之間設置反射片 204’以將光反射回導光板206a。此外，另可依產品需求， f 而選擇性地設置至少一光學膜片222，例如稜鏡片、擴散片 等’於導光板2〇6a之上表面220上。膠框23〇a則設置在導 光板206a之上表面220的外圍區上，其中膠框23〇a之一側 夾設在光源反射罩212a之側板228a與導光板206a之上表 面220之間，且膝框230a之相對一侧則壓設在光學膜片222 之外圍區域上’而使光學膜片222之外圍區域夾設在膠框 230a與導光板206a之上表面220之間，如第2A圖所示。 因此，在此侧邊入光式背光模組2〇〇a中，光源反射罩2 12a Ο 係設置在對應之光源210的外側，且並罩設在背板202a與 膠框230a之外側之外，如第2A圖所示。此時，光源21〇 係位於背板202a、導光板206a、膠框230a與光源反射罩 212 a所構成之空間中。 在本示範實施例中，光源組208的固定係利用鎖固在膠 框230a的方式。光源反射罩212a之位於導光板⑼以上^ •側板228a中設有至少一鎖固孔232，例如螺孔，且膠框23〇a *亦設有至少一鎖固孔234，例如螺孔，與側板228a之鎖固 . 孔232對應且互相連通。側邊入光式背光模組2〇〇a更具有 10 201003232 至少一鎖固元件2 3 6，例如螺絲，可對應穿設並依序鎖入光 - 源反射罩212a之鎖固孔232與膠框230a之鎖固孔234，藉 以使光源反射罩212 a固定於膠框2 3 0 a上，進而使光源組 208有效地固設在整個側邊入光式背光模組200a之外側。 在側邊入光式背光模組200a中，由於光源組208係設 置在膠框23 0a與背板202a之外侧，因此導光板206a之側 面21 8與相對之光源反射罩21 2a之側板226a之間空間可在 不增加側邊入光式背光模組200a之體積下獲得增加，故此 光源組2 0 8中之先源210之間的距離、導光板2 0 6 a與光源 210之間的距離、以及光源210與光源反射罩212a之間的 距離均可增大。如此一來，可有效降低光源21〇與光源21〇、 導光板206a與光源210、以及光源210與光源反射罩212a 之間發生碰撞而產生噪音或光源2 1 0損毁之可能性。此外， 由於光源組2 0 8係設置在側邊入光式背光模組2 〇 〇 a之外 側’因此可直接裝設與拆除光源組208，故在組裝、拆卸與 維修上均相當便利。 ’ 除了上述實施例之外’本發明更包括其他各種不同的實 施樣態。舉例而言’請參照第3圖，其係繪示依照本發明第 二較佳實施例的一種側邊入光式背光模組之剖面示意圖。在 此示範實施例中’光源組208亦可藉由鎖固在導光板2〇6b
