200941077 九、發明說明： 【發明所屬之技術領域】 本發明係關於一種反射片結構，特別是有關於一種應用於 直下式背光模組之燈管支撐架，能防止反射亮度不均之反射片 結構。 【先前技術】 背光模組為液晶顯示器面板的主要零件之一，液晶本身並 不會發光，依靠背光模組提供光源，以使液晶顯示器面板能顯 示影像，目前液晶顯示器面板應用在越來越多的電子產品，如 電視、電腦螢幕、手機、數位相機等等，要求也越來越高，背 光模組若無法提供充足而均勻之光源，勢必影響到液晶顯示器 面板顯示影像的效果。 背光模組主要分為側光式以及直下式。側光式背光模組之 光源置於侧邊，經由導光板及反射板將光導引至液晶顯示器面 板。直下式背光模組之光源置於液晶顯示器面板之下方，利用 反射片結構將光反射至液晶顯示器面板。對於直下式背光模組 而言，請參閱第1圖，係為一段式斜面之燈管支撐架110的局 部立體圖，其中燈管支撐架110包括至少一分隔片122，相鄰 的兩片分隔片122之間係用以放置燈管（未圖示）。目前燈管支 撐架110之設計係使用黑色材質製作，而為了獲得均勻的亮 度，在分隔片122之第一表面124上貼附有白色的反射片結構 130。 為了更加提高亮度以及均勻度，目前之燈管支撐架已有兩 段式斜面的設計。請參閱第2圖，係為兩段式斜面之燈管支撐 架210的局部立體圖，其中燈管支撐架210至少包括一固持壁 200941077 221以及至少一分隔片222，相鄰的兩片分隔片222之間係用 以放置燈管（未圖示）。兩段式斜面之燈管支撐架210係使用黑 色材質製作，而為了獲得均勻的亮度，在固持壁221以及分隔 片222之第一表面224上貼附有白色的反射片結構230。由於 固持壁221以及第一表面224形成兩段式斜面結構的關係，容 易使第二段斜面上（亦即第一表面224)之反射片剝離，尤其是經 過信賴性測試後，例如溫度試驗、溼度試驗、機械衝擊試驗、 振動試驗等，第一表面224上之反射片剝離或是翹起會造成反 ® 射亮度不均。一般而言，一段式斜面較無上述問題，在兩段式 斜面之燈管支撐架210則容易發生上述情況。 【發明内容】 本發明之目的係提供一種防止反射亮度不均之反射片結 構，用於避免燈管支撐架之反射片剝離或是翹起造成反射亮度 不均的情況發生。 根據本發明之反射片結構，係應用於背光模組之燈管支撐 架，該燈管支撐架具有固持壁及至少一分隔片自該固持壁延伸 〇 突出並具有一第一表面、一第二表面實質上垂直於該第一表 面，以及一第三表面實質上垂直於該第二表面並面對該第一表 面，該反射片結構包含：一平板部，附著於該燈管支撐架之固 持壁上；至少一第一延長部，從該平板部延伸突出並可附著於 該分隔片之第一表面；一第二延長部，自該至少一第一延長部 延伸突出並可附著於該分隔片之第二表面；一第三延長部，以 相反於第一延長部延伸之方向，自該第二延長部延伸突出，並 可附著於該分隔片之第三表面。 本發明之另一目的係提供一種防止反射亮度不均之燈管支 200941077 撐架，用於背光模組，該燈管支撐架包含一固持壁；至少一分 隔片，自該固持壁延伸突出並具有一第一表面、一第二表面實 質上垂直於該第一表面，以及一第三表面實質上垂直於該第二 表面並面對該第一表面；以及一反射片結構該反射片結構包 含：一平板部，附著於該燈管支撐架之固持壁上；至少一第一 延長部，從該平板部延伸突出並可附著於該分隔片之第一表 面，一第二延長部，自該至少一第一延長部延伸突出並可附著 於該分隔片之第二表面；以及一第三延長部，以相反於第一延 長部延伸之方向，自該第二延長部延伸突出，並可附著於該分 隔片之第三表面。 藉由上述之反射片結構以及燈管支擇架，當燈管支樓架與 背板組裝時，反射片之第二延長部以及第三延長部在燈管支撐 架的固定阻擋下，使反射片之平板以及第一延長部不會有翹起 或剝離之情況發生，解決習知燈管支撐架由於反射片翹起或剝 離造成輝度不均的問題。 【實施方式】 〇 以下將就圖式詳細說明本發明之技術内容。 請同時參閱第3圖和第4圖，其中第3圖係根據本發明之 反射片結構330應用於兩段式斜面之燈管支撐架31〇的局部立 體圖，第4圖則為第3圖之燈管支撐架310上下翻轉後之局部 立體圖。兩段式斜面之燈管支撐架310係由黑色材質製作，其 包含：架體315、固持壁321、複數個分隔片322及反射片結 構330 ’其中固持壁321自主體一邊延伸而出並形成一斜面， 複數個分隔片322自固持壁321之斜面延伸突出。分隔片322 具有第一表面324、第二表面326及第三表面328,其中第一 200941077 表面324與固持壁321之斜面斜向對應第 垂直於第-表面324,第三表 由326霣質上 ... & 面328實質上垂直於第二表面 326，並面對第一表面324。® 4 A、 ^ AumMAA： I 轉壁321與分隔片322係使用同 一黑色材質製作。每兩個分隔 阳乃322之間形成一凹播340用於 容置-對應的燈管（未圖示）。 肖340用於 反射片結構330包含平板 取邵332、第一延長邱筮一 延長部336及第三延長部338 负部334第一 Ο 〇 M0之固持壁321上。第一延長部3^ 332附著於燈管支撐架 益可附著於分隔片322之第一表 從平板部332延伸突出 一延長部334延伸突出並可附著於分军二延長部336自第 326。第三延長部338以相反於第〜 隔片322之第二表面 自第二延長部336延伸突出，並可附^長部334延伸之方向’ 面328。為了獲得均勻的亮度，附著於、片322之第二表 322上之反射片結構330(包含平板332固持壁321以及分隔片 延長部336以及第三延長部338)為〜令第一延長部334、第二 成’並以黏貼方式附著於燈管支律架反射率之白色材質所製 之形狀係符合燈管支撐架310之固持。反射片結構330 隔片322之上述各表面的形狀。也就21之表面形狀以及分 長部334 '第二延長部336以及第三越i平板332、第一延 符合固持壁321、第-表面324、第_，部338之形狀係分別 328之形狀。 〜表面326以及第三表面 請同時參閱第5A圖以及第5B圖 味 ，，Λ # 第5Α圓係為燈管支撐 架310裝設於背板350之立體圖。第知 , m _係為第5A圖之部位 C的放大圖。本實施例中，當燈管支揸 七够 , 导架310裝設於背板350 時’第二延長部336會恰與背板35〇 电部之内表面360貼合。 200941077 縱然經過信賴性測試或其他意外狀況，由於第二延長部336與 背板350底部之内表面360貼合產生了阻擋的功能，連帶使平 板部332及第一延長部334也不會有翹起或剝離而造成輝度不 均的問題，故本發明可有效解決習知技術的缺點。另一實施例 中，第二延長部336與背板350底部之内表面360並未貼合而 具有一間隙，但即使第三延長部338剝離，由於背板350底部 之内表面360仍具有阻擋功能，因此平板部332及第一延長部 334還是不會有翹起或剝離之情況。 © 請同時參閱第6A圖以及第6B圖；第6A圖係為根據本發 明之反射片結構330之局部平面圖，第6B圖係為習知的反射 片結構330之局部平面圖。如第6A圖所示，反射片結構330 包含：平板部332、第一延長部334、第二延長部336以及第 三延長部338。如第6B圖所示，習知的反射片結構330只包含 平板部332以及第一延長部334。第7A圖係為第6A圖之反射 片結構330之立體圖，第7B圖係為第6B圖之反射片結構330 之立體圖，從第7A圖及第7B圖比較後可清楚知道，由於本發 ❹ 明具有第二延長部336以及第三延長部338反折至分隔片 322(第3圖）之第二表面326以及第三表面328，使得主要提供 反射之平板部332以及第一延長部334不會翹起或剝離，進而 達到提供均勻亮度之目的。 雖然本發明已以實施例揭露如上，然其並非用以限定本發 明，任何具有本發明所屬技術領域之通常知識者，在不脫離本 發明之精神和範圍内，當可作各種更動與潤飾，並可思揣其他 不同的實施例，因此本發明之保護範圍當視後附申請專利範圍 所界定者為準。 200941077 【圖式簡單說明】 第1圖係為一段式斜面之燈管支撐架的局部立體圖； 第2圖係為兩段式斜面之燈管支撐架的局部立體圖； 第3圖係根據本發明之反射片結構應用於兩段式斜面之燈 管支撐架的局部立體圖； 第4圖係為第3圖之燈管支撐架上下翻轉後之局部立體 EI · 園， 第5A圖係為燈管支撐架裝設於背板之立體圖； ® 第5B圖係為第5A圖之部位C的放大圖； 第6A圖係為根據本發明之反射片結構之局部平面圖； 第6B圖係為習知的反射片結構之局部平面圖； 第7A圖係為第6A圖之反射片結構之立體圖；以及 第7B圖係為第6B圖之反射片結構之立體圖。 【主要元件符號說明】 110、210、310 燈管支撐架 115 、 215 、 315 架體 122 ' 222 ' 322 分隔片 124 ' 224 ' 324 第一表面 130 ' 230 ' 330 反射片結構 221 、 321 固持壁 332 平板 334 第一延長部 326 第二表面 328 第三表面 336 第二延長部 200941077 338 第三延長部 340 凹槽 350 背板 360 内表面200941077 IX. Description of the Invention: [Technical Field] The present invention relates to a reflective sheet structure, and more particularly to a lamp support frame for a direct type backlight module, which can prevent a reflection sheet structure with uneven reflection brightness . [Prior Art] The backlight module is one of the main components of the liquid crystal display panel. The liquid crystal itself does not emit light. The backlight module is used to provide a light source, so that the liquid crystal display panel can display images. Currently, the liquid crystal display panel is applied more and more. Electronic products, such as televisions, computer screens, mobile phones, digital cameras, etc., are also becoming more and more demanding. If the backlight module cannot provide a sufficient and uniform light source, it will inevitably affect the effect of displaying images on the LCD panel. The backlight module is mainly divided into a side light type and a direct type. The light source of the edge-lit backlight module is placed on the side, and the light is guided to the liquid crystal display panel via the light guide plate and the reflector. The light source of the direct type backlight module is placed under the liquid crystal display panel, and the light is reflected to the liquid crystal display panel by the reflective sheet structure. For a direct type backlight module, please refer to FIG. 1 , which is a partial perspective view of a one-slope lamp tube support frame 110 , wherein the lamp tube support frame 110 includes at least one separator piece 122 and two adjacent pieces of the separator piece. The 122 is used to place a lamp (not shown). At present, the design of the lamp support frame 110 is made of a black material, and in order to obtain uniform brightness, a white reflective sheet structure 130 is attached to the first surface 124 of the separator 122. In order to improve brightness and uniformity, the current lamp holder has a two-stage bevel design. Referring to FIG. 2, a partial perspective view of a two-stage beveled lamp tube support 210, wherein the lamp support frame 210 includes at least one retaining wall 200941077 221 and at least one partition 222, two adjacent separator sheets 222 Used to place a lamp (not shown). The two-stage beveled lamp tube support 210 is made of a black material, and a white reflective sheet structure 230 is attached to the first surface 224 of the holding wall 221 and the separator 222 in order to obtain uniform brightness. Since the holding wall 221 and the first surface 224 form a two-stage bevel structure, it is easy to peel off the reflective sheet on the second inclined surface (ie, the first surface 224), especially after the reliability test, such as temperature test, In the humidity test, the mechanical impact test, the vibration test, etc., the peeling or lifting of the reflection sheet on the first surface 224 may cause uneven brightness of the counter-reflection. In general, a one-step bevel has no such problem, and the lamp holder support 210 of the two-stage bevel is prone to the above.
