Description
本發明是有關於一種藉由包含K-Si-F類螢光體及色純度增強膜而使得色純度的提高極大化的液晶顯示裝置。
以前,40英寸(")的電視為主流,而現在出現了很多購買50"、進一步為60"電視的消費者。在這種對於尺寸的競爭結束後,開始了對於分辨率的競爭。在一年前全高清(FHD)級別就已經屬於高級型號,但是現在超高清(UHD)正在急速擴散到市場上。
最近的顯示器市場正在從大螢幕、高分辨率競爭進化為色彩競爭。由於這種原因,對具有優異色彩的顯示器的製備方面的競爭呈上升趨勢。
液晶顯示裝置(liquid crystal display,LCD)是利用液晶(liquid crystal)的光學特性來顯示圖像,但由於顯示圖像的液晶面板為不能自身發光的非發光型元件,因此液晶顯示裝置具有包含與液晶面板一起在其背面配置有對液晶面板供給光的背光單元(back-light unit)的結構。液晶顯示裝置作為用於移動設備、電腦的顯示螢幕及高清
晰度電視(HDTV)等的顯示裝置而受到關注,但是在色彩方面與其它顯示裝置相比有所落後。
此外,最近為了實現高色彩再現顯示器而提出的多種解決方案中,最為活躍地進行開發的是將包含K-Si-F類螢光體的紅色螢光體用於發光元件封裝中的顯示器(參見韓國公開專利第2015-0082426號及日本公開專利第2010-93132號)。但是,在為了UHD廣播而改變畫質規範的實際情況下,藉由使用K-Si-F類螢光體的發光元件封裝而能夠實現的色彩再現水平對於較新的規範來說處於不足的水平。
為此,需要能夠將現有的LCD的色純度跨越性地提高至新的規範水準的新技術。
因此,本發明的目的在於,提供藉由最大限度地透射從光源發出的純RGB波長,並阻斷RGB波長以外的不必要的波長,從而能夠極大化地提高液晶顯示裝置的色純度的液晶顯示裝置。
為了實現上述目的,本發明提供包含背光單元及液晶面板的液晶顯示裝置,背光單元包含含有K-Si-F類螢光體的白色發光元件封裝;背光單元、液晶面板或兩者的結構中均具備一個以上的塗層或黏附層,該一個以上的塗層或黏附層包含吸收特定波段的一種以上的吸收染料。
根據本發明,藉由將吸收特定波段的一種以上的吸收染料導入到液晶顯示裝置的黏附層或塗層中,並將K-Si-F類螢光體應用於發光元件封裝中,從而最大限度地透射從光源發出的純RGB波長,並阻斷RGB波長以外的不必要的波長而提高色域(gamut),藉此能夠製造出色純度得到極大化提高的液晶顯示裝置。

圖6至圖8為實施例1、比較例1及比較例2的液晶顯示裝置的發光光譜的曲線圖。
本發明的液晶顯示裝置包含背光單元及液晶面板,背光單元包含含有K-Si-F類螢光體的白色發光元件封裝,背光單元、液晶面板或兩者的結構中均具備一個以上的塗層或黏附層,一個以上的塗層或黏
附層包含吸收特定波段的一種以上的吸收染料。
圖1中表示了本發明一實施方案的液晶顯示裝置的結構示意圖。
參照圖1,液晶面板10以依次層壓的形態包含上偏光板101、第一黏附層102、液晶單元(liquid crystal cell)103、第二黏附層104及下偏光板105,背光單元20可以依次包含選自雙重亮度增強膜(Double Bright Enhancement Film,DBEF)211或上擴散片221、水平棱鏡片202、垂直棱鏡片203、下擴散片204、導光板205及反射板206中的兩種以上。
此外,參照圖2a至圖2d,雙重亮度增強膜211可以具有多層的結構(未圖示),上擴散片221在擴散片基材221-3的一面上可以具有具備第一珠(bead)221-1的擴散塗層221-2,相反面上可以具有具備第二珠221-5的用於防止浸透(wet-out)的珠塗層(隱蔽塗層)221-4。進一步地,水平棱鏡片202在棱鏡片基材202-2的一面上可以具有棱鏡圖案層202-1,相反面上可以具有具備第三珠202-4的背面塗層202-3。此外,垂直棱鏡片203也可以具有與水平棱鏡片202相同的層結構。此外,下擴散片204可以具有與上擴散片221相同的層結構。進一步地,反射板206在反射板基材206-3的一面上可以具有具備第四珠206-1的正面塗層206-2。
但是,本發明的液晶顯示裝置不限於上述結構,根據需要可以進行多種變形。
觀察液晶顯示裝置的基本原理可知,從光源發出的光經過導光板被引導至液晶面板方向後,藉由光擴散片的同時向垂直於面的水平/垂直方向擴散,從而使得光亮度急劇下降,因此將使從光擴散片發出
的光藉由棱鏡片,從而阻擋光從出光面正面以外的方向出去,並提高光定向性而縮小視角,藉此增大背光出光面正面方向的亮度。此時,在背光單元中可以使用如雙重亮度增強膜等另外的片材,從而能夠藉由光回收利用(recycling)使亮度增大極大化。
根據本發明,背光單元、液晶面板或兩者的結構中均具備塗層或黏附層,塗層或黏附層包含吸收特定波段的一種以上的吸收染料。
液晶面板依次包含上偏光板、第一黏附層、液晶單元、第二黏附層及下偏光板,第一黏附層、第二黏附層或兩者均可以包含吸收特定波段的一種以上的吸收染料。例如,黏附層可以在上偏光板及下偏光板的一面或兩面上藉由濕式塗布來形成。
黏附層的厚度可以為2~100μm、5~100μm或15~25μm。
此外,黏附層可以包含減壓性黏合劑。減壓性黏合劑可例舉如選自丙烯酸類、氨基甲酸乙酯類、環氧類及矽類黏合劑中的一種以上。具體地,減壓性黏合劑可以為丙烯酸類黏合劑。
背光單元可以依次包含選自雙重亮度增強膜(DBEF)或上擴散片、棱鏡片、下擴散片、導光板及反射板中的兩種以上,雙重亮度增強膜或上擴散片的一面或兩面、棱鏡片的一面或兩面、下擴散片的一面或兩面、導光板的一面或兩面及反射板的一面中的一個以上的位置上具有塗層,塗層可以包含吸收特定波段的一種以上的吸收染料。例如,塗層可以在雙重亮度增強膜或上擴散片的一面或兩面上、棱鏡片的一面或兩面上、下擴散片的一面或兩面上、導光板的一面或兩面上或反射板的一面(即導光板的相對面)上藉由濕式塗佈來形成。
棱鏡片可以為水平棱鏡片、垂直棱鏡片或其組合。
塗層的厚度可以為1~100μm、2~100μm或2~15μm。

將包含吸收染料的黏附層及塗層稱為色純度增強膜,根據色純度增強膜的位置,尤其是根據塗層的位置,液晶顯示裝置的發光色純度及亮度損失會不同,因此可以根據需要適當調節其位置。
此外,吸收染料可以為主吸收波段為RGB以外的波段的吸收染料的至少一種以上的組合。具體地,吸收染料可以具有380~430nm、480~510nm或560~600nm的主吸收波段。例如,螢幕蔽380~430nm的波段的吸收染料可以例舉如羥基苯並***(Hydroxy benzotriazole,HB)類、三-間苯二酚-三嗪發色團(Tris-Resorcinol-Triazine chromophore,TRTC)類、羥苯基-苯並***發色團(Hydroxylphenyl-benzotriazole chromophore,HBC)類吸收染料;螢幕蔽480~510nm波段的吸收染料可以例舉如吡咯次甲基(pyrrole methine,PM)類、若丹明(Rhodamin,RH)類、硼二吡咯亞甲基(Boron Dipyrromethene,BODIBY)類吸收染料;螢幕蔽560~600nm的波段的吸收染料可以例舉如四氮雜卟啉(Tetra aza porphyrin,TAP)類、若丹明類,方酸菁(Squarine,SQ)類、花青(Cyanine,CY)類吸收染料。
吸收染料可以選自羥基苯並***(HB)類、三-間苯二酚-三嗪發色團(TRTC)類、羥苯基-苯並***發色團(HBC)類、吡咯次甲基類、若丹明類、硼二吡咯亞甲基類、四氮雜卟啉類、方酸菁類及花

以塗層或黏附層總重量計,可以包含0.01~10重量%的吸收染料。具體地,以塗層或黏附層總重量計,可以包含0.05~7重量%的吸收染料。
為了阻斷紫外光,黏附層及塗層可以進一步包含紫外線阻斷劑。紫外線阻斷劑用於吸收(屏蔽)430nm以下的光,例如,可以單獨或混合兩種以上來使用羥基苯並***(HB,hydroxy benzotriazole)類、三-間苯二酚-三嗪發色團(TRTC,tris-resorcinol-triazine chromophore)類或羥苯基-苯並***發色團(HBC,hydroxylphenyl-benzotriazole chromophore)類紫外線阻斷劑。

黏附層及塗層的透光率可以根據液晶顯示裝置的亮度範圍來進行調整,具體地,可以具有30~90%或50~90%的可見光透光率。
此外,背光單元的白色發光元件封裝包含含有K-Si-F類螢光體的樹脂層,及發出能夠激發K-Si-F類螢光體的近紫外線或藍色光的發光元件。
圖3中表示了本發明一實施方式的白色發光元件封裝的結構的示意圖。在圖3中概略地表示出了發光元件330,但水平型發光元件或垂直型發光元件均可以利用,例如,其可以為氮化物半導體發光二極管(LED)芯片。
參照圖3及圖4,白色發光元件封裝300包含一對引線框310、320和根據電壓的施加而發光的發光元件330。
發光元件330與引線框310、320是藉由電線340進行電連接,發光元件330上藉由澆鑄(moulding)形成有包含K-Si-F類螢光體的樹脂層350。樹脂層350可以藉由澆鑄形成在發光元件330的整個周圍,但根據需要也可以藉由澆鑄而部分地形成在發光部位。即,在高輸出發光元件的情況下,因發光元件330的大型化而進行整體澆鑄時,會不利於分散在透光性樹脂中的螢光體370的均勻分散。在這種情況下,在發光部位進行部分澆鑄會有利。
發光元件330可以發出能夠激發K-Si-F類螢光體370的近紫外線或藍色光。具體地,發光元件可以發出350~460nm波長區域的藍色光。
樹脂層350是藉由澆鑄形成在發光元件上,並可以包含透光性樹脂及分散在透光性樹脂中的K-Si-F類螢光體370(參見圖4)。透光性樹脂可以包含選自環氧樹脂、矽樹脂、聚醯亞胺樹脂、尿素樹脂及丙烯酸樹脂中的一種以上。具體地,可以為環氧樹脂或矽樹脂。
以透光性樹脂100重量份計,樹脂層可以包含0.01~20重量份的K-Si-F類螢光體。具體地,以透光性樹脂100重量份計,可以包含1~10重量份的K-Si-F類螢光體。
K-Si-F類螢光體370可以為K2SiF6:Mn紅色螢光體。K2SiF6:Mn是指摻雜四價錳(即Mn4+)的K2SiF6,其是指一部分作為四價陽離子的矽被錳所取代。具體地,摻雜四價錳的K2SiF6可以顯示為K2Si1-mMnmF6,所述m可以為0.001~0.15,詳細地,可以為0.01~0.12。
此外,樹脂層除了K-Si-F類螢光體之外,可以根據需要進一步包含各種綠色螢光體、紅色螢光體、琥珀色(amber)螢光體及它們的組合。
此外,樹脂層350上可以具備封閉元件整體的外部空間的外裝材料360。
白色發光元件封裝可以發出420~700nm的波長區域的寬波長的白色光。
構成本發明的液晶顯示裝置的背光單元及液晶面板各個結構層可以具有本發明所屬領域中通常允許的材質、厚度、形態等,且根據需要可以進行多種變形。
如上所述,本發明的包含K-Si-F類螢光體及色純度增強膜的液晶顯示裝置可以最大限度地透射從光源發出的純RGB波長,並阻斷RGB波長以外的不必要的波長,從而可以提供得到提高的色域及亮度,並且藉由自由地移動色純度增強膜的位置,從而可以根據顯示裝置的特性來極大化色純度提高效果。
實施例
下面,將藉由下述實施例更詳細地說明本發明。但是,下述實施例僅用於例示本發明,本發明的範圍並不僅限定於此。
實施例1
混合25重量%的丙烯酸黏合劑樹脂(綜研化學株式會社(Soken),GS1000)和75重量%的甲基乙基酮(methylethetylketone,MEK),從而製備溶液,然後以溶液100重量份計,添加0.05重量份的吸收染料(SK化學公司,SK-d593,主吸收波段:560~600nm),
從而製備塗層組合物。
利用邁爾棒(mayer bar)在擴散膜(製造商:愛思開哈斯(SKC-HAAS),產品名:CH19)的一面上塗佈塗層組合物,並進行乾燥及固化而形成厚度為5μm的塗層(色純度增強膜),然後將形成有塗層的擴散膜作為下擴散板而導入到液晶面板上,以使塗層朝嚮導光板,從而製得本發明的液晶顯示裝置(參見圖5)。
此時,使用了背光單元,背光單元使用了包含K-Si-F類螢光體(K2SiF6:Mn)的白色發光元件封裝。具體地,背光單元使用了依次層壓雙重亮度增強膜、水平棱鏡片、垂直棱鏡片、下擴散片、導光板及反射板的結構。
比較例1
在下擴散板的一面上沒有形成包含吸收染料的塗層,並且使用的背光單元為使用了包含釔鋁石榴石(YAG)螢光體(Y3Al5O12)的白色發光元件封裝的背光單元(製備公司:LG電子,產品名:55UB8400)之外,製備了與實施例1具有相同結構的液晶顯示裝置。
比較例2
在下擴散板的一面上沒有形成包含吸收染料的塗層外,製備了與上述實施例1具有相同結構的(即,沒有改變結構而是與市售的產品相同的結構)液晶顯示裝置。
實驗例1
利用輻射計(radiometer,CS-2000;美能達(Minolta))對實施例1、比較例1及比較例2的液晶顯示裝置進行光譜的變化及特性的測定,並將其結果顯示在表1及圖6~圖8中。色域顯示出色彩再現
面積。
如上述表1中所示,與使用YAG螢光體的液晶顯示裝置的比較例1相比,使用K-Si-F類螢光體的液晶顯示裝置的比較例2及實施例1顯示出得到提高的色純度。但是,在使用K-Si-F類螢光體的液晶顯示裝置上進一步使用色純度增強膜的實施例1比比較例2顯示出得到提高的色純度。因此,可以期待包含本發明的色純度增強膜的液晶顯示
裝置能夠滿足作為UHD標準使用的數位電影系統技術規範(DCI)或超高清電視國際標準(BT.2020)規範。
