M341857 八、新型說明： 【新型所屬之技術領域】 本新型是有關於一種背光模組，特別是有關於一種可 供多面顯示之平面顯示器之背光模組。 【先前技術】 當今背光模組以大發光面積之平面光源為目前的發展 趨勢，尤其更被大尺寸面板液晶顯示器之廠商所重視。傳 統液晶顯示器之光源係應用冷陰極燈管（cold cathode Fluorescent lamp，CCFL )、外部電極螢光管技術（external electrode fluorescent lamp ; EEFL )、發光二極體技術（light emitting diode ; LED )、奈米碳管技術（carbon nanotube ; CNT )、平面光源技術（Flat Fluorescent Lamp ; FFL )以及 有機發光二極體技術（organic light emitting display; OLED)等，均以發出可見光波長之光的方式，以提供液 晶顯示器之照明光源。 這些發出可見光波長之光源類型中，例如冷陰極燈管 (CCFL )，係於一真空燈管中内壁塗覆一螢光層（如：磷）， 並在此真空燈管中内部封入少量惰性氣體及汞蒸氣，汞蒸 氣於電極放電過程中經電子衝擊而產生紫外光，紫外光經 撞擊真空燈管壁上之螢光層而轉換為可見光，而對外釋出 可見光波長。 然而，此種冷陰極燈管（CCFL)受限於螢光塗層需 M341857 與發光源置於同一真空燈管中，且於傳統冷陰極燈管製 程’螢光層之原料（如：填泥）由直立時之真空燈管頂端衣 依序由其頂部至底部利用重力塗佈於真空燈管内壁，因此 螢光塗層不易塗佈均勻，則真空燈管所發出之可見光波長 便無法有效均句，此現象於大尺寸管柱真空燈管更為明顯。 而液晶顯示器具冷陰極燈管之背光模組時，於追求薄 型化之過程中’會嘗試縮短其液晶面板與f光模組之光源 間之距離，倘若液晶面板與照明模組間之距離不當，則光 之干涉與反射現象會益加明顯’並因此於照亮區域所造成 之輝度差異，稱作光不均勻現象（mura)，降低照明品質。 此外，具冷陰極燈管之背光模組應用於雙面螢幕之液 晶顯示器時’由於冷陰極燈管所釋出之可見光波長通過一 面螢幕之擴散片時’由於能量之消逝’無法有效被反射至 另面螢幕’以提供強化另一面螢幕之照明光源，使得雙 面螢幕照亮區域外之位置仍有不均勻照明之缺點。 口此有I於上述利用可見光波長之冷陰極燈管所發 展之薄型平面顯示器’於追求薄型化之過程中，所面臨光 不均勻現象之缺點’勢必無法於平面顯示器之銷售市場 中^到消費者之肯定’故，發展一可供多面顯示之平面 頁不益及其为光模組’而提供一可同時具有均句照明及薄 型化優點之解決方案，，提供多種類選擇之多面顯示 器，便為現今業界共同努力之目標。 M341857 【新型内容】 ，以降低發 本新型之目的之-是在提供—種背光模組 射光之光不均勻現象。 種背光模組，以強化其 源’均勻照亮區域外位 本新型之目的之一是在提供_ 他螢幕或螢幕之其他位置之照明光 置之亮度。 種背光模組，以使所搭 之目標。 種背光模組，提供一背 本新型之目的之一是在提供— 配之平面顯示器，達成薄型化優點 本新型之目的之一是在提供一 光模組之薄型化體積的解決方案。 本新型之目的之—是在提供—種背光模組，提供光源 發光7G件排列之多種組合方式。 此根據眾述之目的，本新型提供一種背光模組，其中之 背光模組包括-光源及多個波長轉換結構，光源由^個發 先兀件所組成，此些發光元件分別以輻射之方向發出第一 種光波長之光，而此些波長轉換結構設置於鄰近光源 置，當此些波長轉換結構接受第一種光波長之光時，便分 別使其轉換為第三種光波長之光，並輻射地發出該些第二 種光波長之光’其中—部份之第二種光波長之光麵別由 對應之波長轉換結構朝外發出，而另—部份之第二種光波 長係各別自此波長轉換結構而朝其他波長轉換結構發出 本新型之另一態樣，係提供一種背光模組，應用於一 可供多面顯示之平面顯示器，其中之背光模組包括一光源 M341857 及一波長轉換結構’光源由多個發光树所排列而成，而 此波長轉換結構㈣此光源，當此些發光元件分別以輻射 之方向發出弟-種光波長之光至此波長轉換結構時，此波 長轉換結構便轉換此些第一種光波長之光為第二種光波長 之光，並以輻射之方向發出第二種光波長之光，如此_部 :分弟二種光波長之光朝外釋出，另—部份第二種光波長則 朝此波長轉換結構之其他位置發出。 本新型之另外-目的是在提供一種可供多面顯示之平 面顯不器，以提供多種類選擇之平面顯示器。 為達成此目的，本新型依據上述之背光模組而提供二 種：供多面顯示之平面顯示器之態樣，其一平面顯示器包 括複數個顯示面板及—背光模組，此些顯示面板相互圍 繞，其中並形成-可容納背光模組之容納空間，背光模組 包括-光源及多個波長轉換結構，光源由多個發光元件所 組成’此些發光元件分別以輻射之方向發出第一種光波長 之光，而此些波長轉換結構設置於鄰近光源之位置，此些 波長轉換結構並於接受此些第一種光波長之光時，而使： 轉換為第二種光波長之光’並以輻射之方向發出第二種光 波長之光，如此一部份第二種光波長之光朝外釋出，另一 部份第二種光波長則朝其他波長轉換結構發出。 ^另一態樣之平面顯示器可包括一捲曲之顯示面板及一 背光模組，此顯示面板圍繞出一可容納背光模組之容納空 間’背光模組設於容納空間中，包括一光源及一波長轉換 結構’光源由多個發光元件所排列而成，而此波長轉換結 M341857 構圍繞此光源，當此些發光元件分別以輻射之方向發出第 一種光波長之光至此波長轉換結構時，此波長轉換結構便 轉換此些第一種光波長之光為第二種光波長之光，並以輻 射之方向發出第二種光波長之光，如此一部份第二種光波 長之光朝外釋出，另一部份第二種光波長則朝此波長轉換 結構之其他位置發出。 【實施方式】 以下將以圖示及詳細說明清楚說明本新型之精神，如 熟悉此技術之人員在瞭解本新型之實施例後，當可由本新 型所教示之技術，加以改變及修飾，其並不脫離本新型之 精神與範圍。 本新型係揭示出一種可供多面顯示之平面顯示器及其 中之背光模組，請參閱第丨、2圖所示，第i圖為本新型平 面顯不器中一第一實施例之示意圖，而第2圖為本新型第 一實施例之光線運動方向示意圖。其中背光模組1〇包括光 源120及波長轉換結構13〇，光源12〇由多個發光元件 所排列而成，波長轉換結構13〇設置於鄰近光源12〇之位 置，此些發光元件121分別以輻射之方向發出第一種光波 長之光122，此些發光元件121可為一短波段紫外光燈管 (Ultraviolet，簡稱UVc燈管）或藍光之發光二極體元件 等等’其中UVc ：!:登管所發出之第一種光波長之光122為 「UVc」光，係指一種不可見光波長之光，其波長不大於 280 nm之紫外光，例如2〇〇至28〇 nm之光、特別是25〇 M341857 至260 nm之光，尤其是指253.7 nm之光。而藍光之發光 二極體元件所發出之第一種光波長之光122為一種具藍光 波長之光，例如430nm至490nm之光。 其中上述之此些UVc燈管於一燈座11〇中之排列方式 :視其平面顯示器1之螢幕數量或形狀之不同，而排列出 提供各面㈣照明亮度之形狀，其排列方式將詳細地揭露 於後續說明書中。 其中波長轉換結構130可包括多個附著基材131及依 附其上之波長轉換物132，波長轉換物132可由材質為磷 粉、感光材質、螢光色轉換媒介、有機錯合物材質、發光 顏料、量子點為底材質、量子線為底材質、或量子阱為底 材質所製成之組合物漿料，而塗佈於附著基材131上，或 附著基材13 1中之任一層面上。 附著基材131為任何合宜之光學元件，除了本身於背 光模組ίο之被運用之特性外，尚提供承載波長轉換物ι32 之功用’例如擴散板（Diffusion plate)、稜鏡片（prism sheet )、凸鏡片（Lenticular Film )、偏光板等硬質光學元 件’·或擴散膜（Diffusion Film )、增亮膜（Brightness Enhancement Film ;

[Prior Art] Today's backlight modules are currently developing with planar light sources with large light-emitting areas, and are particularly valued by manufacturers of large-sized panel liquid crystal displays. The light source of the conventional liquid crystal display is a cold cathode fluorescent lamp (CCFL), an external electrode fluorescent lamp (EEFL), a light emitting diode (LED), a nanometer. Carbon nanotube technology (CNT), flat light source technology (FFL), and organic light emitting display (OLED), etc., all emit light in the visible wavelength to provide liquid crystal The illumination source of the display. Among these types of light sources that emit visible light wavelengths, such as a cold cathode fluorescent lamp (CCFL), a fluorescent layer (such as phosphorus) is applied to the inner wall of a vacuum tube, and a small amount of inert gas is sealed inside the vacuum tube. And mercury vapor, mercury vapor generates ultraviolet light by electron impact during discharge of the electrode, and the ultraviolet light is converted into visible light by impacting the fluorescent layer on the wall of the vacuum lamp tube, and the visible light wavelength is released. However, such a cold cathode fluorescent lamp (CCFL) is limited to the fluorescent coating. The M341857 is placed in the same vacuum tube as the illuminating source, and the raw material of the fluorescent layer in the conventional cold cathode lamp control process (eg, filling mud) The top end of the vacuum tube is placed on the inner wall of the vacuum tube by gravity from the top to the bottom of the vacuum tube. Therefore, the fluorescent coating is not easily coated uniformly, and the visible light wavelength emitted by the vacuum tube cannot be effectively Sentence, this phenomenon is more obvious in large-sized tubular vacuum tubes. When the backlight module of the cold cathode lamp of the liquid crystal display device is in the process of pursuing thinning, 'will try to shorten the distance between the liquid crystal panel and the light source of the f-light module, if the distance between the liquid crystal panel and the lighting module is improper The interference and reflection of light will add to the obvious 'and thus the difference in brightness caused by the illuminated area, called mura, which reduces the quality of illumination. In addition, when the backlight module with the cold cathode lamp is applied to the liquid crystal display of the double-sided screen, the visible light wavelength emitted by the cold cathode lamp can not be effectively reflected due to the disappearance of the screen due to the diffusion of the screen. The other screen 'is provided with an illumination source that enhances the other side of the screen, so that there is still the disadvantage of uneven illumination at the position outside the illuminated area of the double-sided screen. The thin-type flat-panel display developed by the above-mentioned cold-cathode tube using visible light wavelengths in the process of pursuing thinning, the shortcoming of the phenomenon of uneven light is inevitable in the sales market of flat-panel displays. Affirmation of the fact that the development of a flat-panel display for multi-faceted display and its provision for a light module can provide a multi-faceted display with multiple choices of illumination and thinning.
