Description

擴光件及應用該擴光件之發光設備、顯示裝置和電子裝置
本發明涉及一種擴光件及應用該擴光件之發光設備、顯示裝置和電子裝置。
一般大尺寸之LED(發光二極體)發光設備和顯示裝置，為了節約成本，會儘量減少LED模組之使用數量，並藉由使用擴光件遮蓋LED模組，以達到擴光之目之。然而，目前被廣泛使用之擴光件之材質一般為聚碳酸酯(PC)或聚甲基丙烯酸甲酯(PMMA)，將擴光件罩在白光LED上，光線透過該擴光件，即可達到擴光之效果，然而透過這種擴光件之光之顯色性和色域仍然較小。
有鑑於此，有必要提供一種可增加所透過光之顯色性和色域之擴光件。
另，還有必要提供一種應用上述擴光件之發光設備。
另，還有必要提供一種應用上述發光設備之顯示裝置。
另，還有必要提供一種應用上述顯示裝置之電子裝置。
一種擴光件，其材質含有環氧樹脂、過硫酸銨、及量子點，其中環氧樹脂之質量分數為10%~15%，過硫酸銨之質量分數為65%~80%，量子點之質量分數為10%~20%。
一種應用所述擴光件之發光設備，該發光設備包括基板、電性連接該基板用於提供光之至少一個發光二極體模組、及電性連接於該基板與發光二極體模組之控制電路，所述每一發光二極體模組外罩設有一所述擴光件。
一種應用所述發光設備之顯示裝置，該顯示裝置還包括覆蓋於該發光設備上具有擴光件之一表面之顯示面板，該顯示面板用於顯示圖像並接收從發光設備之擴光件所射出之光。
一種應用所述顯示裝置之電子裝置，該電子裝置還包括主體，所述顯示裝置裝設於該主體上。
所述擴光件之材質含有環氧樹脂、過硫酸銨、及量子點，該擴光件在使用中起到擴光作用之同時，可以在藍光之激發下產生更多的紅光和綠光，達到進一步提高光的顯色性和色域之效果。

圖3為本發明較佳實施方式之顯示裝置之示意圖。
圖4為本發明較佳實施方式之電子裝置之示意圖。
請參閱圖1，本發明一較佳實施方式提供一種用於罩設光源之擴光件100。該擴光件100之材質含有環氧樹脂、過硫酸銨、及均勻分散於前述兩種 材質之間之量子點101。該環氧樹脂之質量分數為10%~15%，過硫酸銨之質量分數為65%~80%，量子點101之質量分數為10%~20%。所述量子點101包括紅光量子點和綠光量子點，該紅光量子點和綠光量子點之質量比為1：1。
所述擴光件100具有相對之兩側，其中一側開設有容納槽103用以容置光源，與容納槽103相對之另一側之表面為擴光面102。該擴光面102為曲面，光線透過該擴光面102時由於折射而發生擴散，從而達到擴光之效果。
可以理解，為避免氧和/或水氣之滲入導致之量子點發光效率降低之問題，可以在擴光件100之擴光面102上封裝一層透光之密封材料，該密封材料可以為低透水之高分子薄膜或超薄玻璃。
本實施例中，所述擴光件100形狀不規則(參圖1和圖3)。可以理解，所述擴光件100還可以根據需要設定為其他之具有擴光效果之形狀，如錐形、多面體型等。
請進一步參閱圖2，一種應用所述擴光件100之發光設備200，其可作為顯示裝置(例如液晶顯示器)中之背光模組、顯示裝置內部之照明設備(例如平板發光裝置)、戶外照明設備(例如街燈、電光標誌等)等。該發光設備200包括基板201、電性連接該基板201並用於提供光之至少一個LED(發光二極體)模組202、至少一個擴光件100、電性連接基板201及LED模組202之控制電路(圖未示)。每一擴光件100罩設於一LED模組202上，且LED模組容置於容納槽103內。該擴光件100用於使光線擴散。該控制電路用於控制LED模組202之通電/斷電。該LED模組202所發出之光為白光，該白光經過擴光件100時，該白光中含有之部分藍光激發擴光件100中之紅色量子點和綠光量子點分別產生紅光和綠光，這樣，經由擴光件100發射出之光含有更多的紅光和綠光，從而進一步提高了光之顯色性和色域。
該控制電路還可以包括對經由擴光件100發射出之光量與預定之光量進行比較之回饋電路(圖未示)，以及存儲關於所期望之亮度或顯色性之資訊之記憶體(圖未示)。
可以理解，所述發光設備200在作為照明器件使用時，還可以在其外表面組裝外殼及透明罩，以方便照明器件之使用。
請進一步參閱圖3，一種顯示裝置300，其包括所述發光設備200、設置於發光設備200上具有擴光件100之表面之顯示面板301。此時該發光設備200即為通常所說之背光模組。
請進一步參閱圖4，一種電子裝置400，其可為電腦顯示器、電子閱讀器、電視機等。該電子裝置400包括主體401和裝設於主體401之顯示裝置300。
所述擴光件100之材質含有環氧樹脂、過硫酸銨、及量子點101，該述擴光件100在使用中起到擴光作用之同時，可以在藍光之激發下產生更多的紅光和綠光，達到進一步提高光之顯色性和色域之效果。
