分別設置在底板220之四邊。背板202可例如為鋼或鋁金屬 板。光源204設於背板202之内，其中光源204可例如為如 φ 圖示之冷陰極燈管或發光二極體（LED)元件（圖未繪示p在 背光模組200中’光源204之數量可依產品需求而定。在一 實施例中’背光模組200可包括數個光源204，在另一未繪 示之實施例中’背光模組200亦可僅包括一個光源204。如 第3圖所示，在本示範實施例中，背光模組2〇〇係一侧邊入 光式背光模組，因此光源204係設置在側牆222内側面，且 背光模組200更包括導光板208，以提高背光模組2〇〇之光 學品質，其中導光板208係設置在背板202内，而光源2〇4 _則介於導光板208與背板202之側牆222之間。在另一未繪 示之實施例中，背光模組可為直下式背光模組，因此光源係 設置在背板202内部之底板22〇上，此時的背光模組則無需 設置導光板。 在一實施例中，背光模組200之多個光源2〇4可對應一 個轉接插座218，且轉接插座218具有一轉接插孔組236， 其中轉接插座218中之轉接插孔組236與對應之光源2〇4 電性連接，以利電力傳送。在另一圆未繪示之實施例中，背 光模組200可具有多數個轉接插座218同時與數個光源 1375091

間’更可因此避免光源電源線226與接頭228之間轉折過大 而容易發生受損、斷線等不良，如第7圖所示另外，膠框 φ 216(請先參照第4、7圖）更可具有一擋牆217，在膠框216 覆蓋背板202而與之結合後’擋牆217可限制轉接插座218 在水平方向外露出凹槽224,避免轉接插座218晃動而受 損。本示範實施例之設計可使轉接插座2 1 8内縮而隱藏在背 板202内。如此一來’當光源電源線226之一端的接頭228 插入轉接插座218後，轉接插座218與接頭228之組合可完 全隱藏在背板202内。在本發明中，轉接插座218之設置位 置可依產品機種與產品設計的不同而調整。 請再次參照第6圖，光源'電源線226係一雙接頭電源 10 1375091 線’其中每個光源電源線226之二端分別設有接頭228與接 頭230。在背光模組200中，光源電源線226係可對應於多 個光源204 »而在另一圖未繪示之實施例之背光模組200 中，光源電源線226亦可僅對應一個光源204，在此情況下， 背光模組200之光源電源線226的數量與光源204之數量相 當，亦即一個光源204對應於一個光源電源線226。如此一 來’對於多插孔組設計之轉接插座218而言（圖未繪示），光 源電源線226之接頭228係插設於轉接插座218之對應其中 % 一光源204的一轉接插孔組236中。如此一來，各個光源 204透過對應之轉接插孔組236以及對應之光源電源線226 而可與外界電力供應裝置電性導通。 在背光模組200中，電源供應器一般係設置在背板202 之底板220的背面上（圖未繪示）。通常，電源供應器至少包 括光源插座，其中電源供應器之光源插座可包括一或多個光 源插孔組分別對應於光源204，以供對應之光源電源線226 之另一端上的接頭230插設。透過電源供應器之光源插座、 φ 光源電源線226以及轉接插座2 1 8，可使光源204與外界電 力供應裝置電性導通。 在背光模組200中，為有效利用光源204所發出之光， 更可選擇性地在背板202之底板220上舖設反射片206,以 提高背光模組200正面之光取出率，如第3圖與第5圖所 示。此外，在背光模組200中，更可依實際產品設計於導光 板208上選擇性地設置光學膜片組2 14，以提升背光模組2〇〇 之發光品質。請再次參照第3圖所示之示範實施例，光學膜 片組2 14位於光源204之上’且光學膜片組214包括依序疊 11 1375091 設之光學膜月210與光學膜片212。光學膜片21〇與光學膜 ' 片212 一般可包括例如增亮膜、擴散片或稜鏡片等。於完成 光學膜片組214之設置後，可利用膠框216罩覆在光學膜片 組214之外緣上’並使膠框216與背板2〇2結合，來固定背 光模組200之内部構件，並且可具有擋牆217防止轉接插座 218外露晃動而受損，而大致上完成背光模組200的組裝。 上述示範實施例之背光模組200可應用在液晶顯示模 組中’而液晶顯示模組又可應用於液晶顯示裝置中，例如液 φ 晶顯示器、液晶電視、筆記型電腦、或可攜式電子設備之螢 幕。舉例而言，請參照第8圖，其係繪示依照本發明一較佳 實施例的一種液晶顯示模組之裝置示意圖。液晶顯示模組 234主要包括背光模組200以及液晶顯示面板232。背光模 組200設於液晶顯示面板232之背面’以提供背光源予液晶 顯示面板232。 在背光模組200中，由於光源204與電源供應器之間的 電性連接係透過轉接插座21 8與具有雙接頭之光源電源線 φ 226，光源電源線226並非直接與光源204不可動地固接而 為可拆卸式的，因此無論在背光模組200之組裝、儲放及運 送過程中’或者是在液晶顯示面板234的組裝過程中，可不 先組設光源電源線226，以避免光源電源線226損壞，而可 大大地提升組裝良率與產品可靠度。其次，由於光源電源線 226係為可拆換式，因此縱使光源電源線226在組裝、儲放 及運送過程中損壞，可直接更換光源電源線226即可，無需 進行大幅度拆卸背光模組200的程序，因此可大幅降低重工 之成本與困難度。此外，工廠的備料僅需準備各種具適合線 12 1375091 ，之光源電源線226以備損壞時#換使用，而不需儲備整個 局早價的背錢組部材，因此可增加備㈣性，並減低零件 部材庫存成本。 由上述本發明示範實施例可知，本發明之一優點就是因 為本發明之背光模組之光源電源線並非固接在光源上，因此 y避免光源電源線在背光模組的組裝過程中受損而可提高 背光模組之組裝良率，進而可大幅降低背光模組之重工成 本。 由上述本發明不範實施例可知，本發明之另一優點就是 因為本發明之液晶顯示模組的背光模組之光源電源線為可 拆換式，因此可減低零件部材的備料成本。 、由上述本發明示範實施例可知，本發明之又一優點就是 因為本發明之液晶顯示裝置的背光模組之光源電源線為可

In this case, the number of light source power lines 226 of the backlight module 200 is equivalent to the number of the light sources 204, that is, one light source 204 corresponds to one light source power line 226. As a result, for the socket jack 218 of the multi-jack group design (not shown), the connector 228 of the light source power cord 226 is inserted into the adapter socket 218 corresponding to one of the light sources 204. In the jack set 236. In this way, each light source 204 can be electrically connected to the external power supply device through the corresponding transfer jack group 236 and the corresponding light source power line 226. In the backlight module 200, the power supply is generally disposed on the back surface of the bottom plate 220 of the back plate 202 (not shown). Generally, the power supply includes at least a light source socket, wherein the light source socket of the power supply may include one or more light source jack sets respectively corresponding to the light source 204 for interposing the joint 230 on the other end of the corresponding light source power line 226 . The light source 204 can be electrically connected to the external power supply device through the light source socket of the power supply, the φ light source power line 226, and the transfer socket 218. In the backlight module 200, in order to effectively utilize the light emitted by the light source 204, the reflective sheet 206 may be selectively disposed on the bottom plate 220 of the back plate 202 to improve the light extraction rate of the front surface of the backlight module 200, such as the third. Figure and Figure 5 are shown. In addition, in the backlight module 200, the optical film group 2 14 can be selectively disposed on the light guide plate 208 according to the actual product design to improve the illumination quality of the backlight module 2 . Referring again to the exemplary embodiment shown in FIG. 3, the optical film set 2 14 is positioned above the light source 204 and the optical film set 214 includes the optical film 210 and the optical film 212 disposed in sequence 1 1375091. Optical film 21 and optical film 'Piece 212 may generally comprise, for example, a brightness enhancing film, a diffusion sheet or a crepe sheet. After the optical film set 214 is completed, the plastic frame 216 can be covered on the outer edge of the optical film set 214, and the plastic frame 216 and the back plate 2〇2 can be combined to fix the interior of the backlight module 200. The member, and may have a retaining wall 217 to prevent the adapter socket 218 from being shaken and damaged, and substantially complete assembly of the backlight module 200. The backlight module 200 of the above exemplary embodiment can be applied to a liquid crystal display module, and the liquid crystal display module can be applied to a liquid crystal display device, such as a liquid crystal display, a liquid crystal television, a notebook computer, or a portable electronic device.
