圖3是本發明又一實施例的一種反射式顯示裝置的架構示意圖。
圖1A是本發明一實施例的一種反射式顯示裝置的架構 示意圖。請參照圖1A，在本實施例中，反射式顯示裝置100包括至少一前光模組110、一第一框體120、一第一液體130以及一顯示單元140。至少一前光模組110包括一光源111以及一導光板113。舉例而言，在本實施例中，第一框體120為一膠框，而顯示單元140可為一電子紙顯示器，但本發明不以此為限。在其他的實施例中，顯示單元140亦可為矽基液晶(liquid crystal on silicon,LCOS)顯示裝置或是大尺寸的反射式顯示媒體。
具體而言，在本實施例中，第一框體120與至少一前光 模組110的導光板113連接。此外，顯示單元140、第一框體120與至少一前光模組110可形成一第一容置空間RS1，且第一液體130配置於於第一容置空間RS1內。更詳細而言，在本實施例中，第一液體130例如是填滿第一容置空間RS1。以下將針對反射式顯示裝置100的製作方法進行進一步的說明。
舉例而言，在本實施例中，反射式顯示裝置100的製作 方法包括下列步驟。首先，提供導光板113，且將光源111配置於導光板113旁。接著，再配置第一框體120，並使第一框體120連接至少一前光模組110的導光板113。更詳細而言，在本實施例中，導光板113包括一入光面113a、一第一表面113b以及一第二表面113c，其中導光板113的第一表面113b與第二表面113c相對，入光面113a並連接第一表面113b與第二表面113c，第一表面113b朝向顯示單元140，且連接第一框體120與至少一前光模組110的導光板113的方法更包括使第一框體120設置於導光板113的第 一表面113b上。
此外，並將顯示單元140配置於第一框體120上。在本 實施例中，由於第一框體120設置於導光板113的第一表面113b上，因此可使顯示單元140、第一框體120與至少一前光模組110形成一第一容置空間RS1。接著，再配置第一液體130於第一容置空間RS1內。具體而言，如圖1A所示，在本實施例中，第一框體120上具有至少一注入孔IH，而可用以注入第一液體130。 換言之，在本實施例中，配置第一液體130於第一容置空間RS1內的方法包括經由注入孔IH注入第一液體130，以使第一液體130填滿第一容置空間RS1，但本發明不以此為限。如此一來，即可形成圖1A所示的反射式顯示裝置100。
進一步而言，如圖1A所示，在本實施例中，光源111設 置於導光板113的入光面113a旁，並適於提供一照明光束60，且照明光束60可經由入光面113a進入導光板113。另一方面，在本實施例中，導光板113更包括位於第一表面113b上的多個光學微結構113d。更詳細而言，如圖1A所示，當照明光束60經由入光面113a進入導光板113時，將可在導光板113傳遞，並被導光板113的第二表面113c反射，且經由這些光學微結構113d至顯示單元140。其中，這些光學微結構113d可在製程中形成所需的形狀，而可滿足自由曲面的應用要求，並使前光模組110能夠提供顯示單元140高亮度且均勻度良好的面光源111。此外，在本實施例中，更可於導光板113的第二表面113c上選擇性地形成圖案化區域(未 繪示)，以增加被反射至顯示單元140的照明光束60的光量。
進一步而言，在本實施例中，導光板113與第一液體130 的折射率比值介於1.02至1.20之間。舉例而言，在本實施例中，第一液體130可為甘油或水。更詳細而言，當第一液體130為甘油時，導光板113的材質可為聚碳酸酯樹脂(Polycarbonate,PC)，其中甘油的折射率為1.47，聚碳酸酯樹脂的折射率為1.58，因此導光板113與第一液體130此時的折射率比值為1.07。另一方面，當第一液體130為水時，導光板113的材質可為壓克力(Polymethyl Methacrylate,PMMA)，其中水的折射率為1.33，壓克力的折射率為1.48，因此導光板113與第一液體130此時的折射率比值為1.11。應注意的是，此處的數值範圍皆僅是做為例示說明之用，其並非用以限定本發明。在其他的實施例中，第一液體130亦可為水與乙二醇依任意比例混合的溶液，或是包括電解質的溶液，或是可搭配不同材質的導光板113使用，以使導光板113與第一液體130的折射率比值可介於1.02至1.20之間。
以下並將搭配圖1B，針對導光板113與第一液體130的 折射率比值與顯示對比以及輝度(luminance)的關係進行進一步的說明。
圖1B是圖1A的導光板113與第一液體130的折射率比 值關係圖。如圖1B所示，在本實施例中，當導光板113與第一液體130的折射率比值接近1時，顯示單元140將可具有較好的顯示對比效果，但前光模組110相對於顯示單元140的輝度較差。 反之，當導光板113與第一液體130的折射率比值越大時，前光模組110的輝度越佳，但顯示單元140的顯示對比效果將會下降。 因此為了兼顧顯示對比效果以及發光效率，在本實施例中，可將反射式顯示裝置100的導光板113與第一液體130的折射率比值控制在1.02至1.20之間。
如此一來，在本實施例中，反射式顯示裝置100可藉由採用液態介面材料(即第一液體130)來取代習知前光模組製程技術中使用的光學膠或是光學透明樹脂，而可簡化製程步驟與降低生產成本。此外，反射式顯示裝置100並可控制導光板113與第一液體130的折射率比值介於1.02至1.20之間，以使反射式顯示裝置100的前光模組110可提供顯示單元140高亮度且均勻度良好的面光源111，並仍保有良好的顯示對比效果。
此外，上述的反射式顯示裝置100雖以具有一配置第一液體130的第一容置空間RS1為例示，但本發明不以此為限。在其他的實施例中，亦可進行多個不同的容置空間的配置，並於各容置空間中注入不同的液體，以下將搭配圖2進行進一步解說。
圖2是本發明另一實施例的一種反射式顯示裝置的架構示意圖。請參照圖2，在本實施例中，圖2的反射式顯示裝置200與圖1A的反射式顯示裝置100類似，而差異如下所述。具體而言，如圖2所示，在本實施例中，反射式顯示裝置200更包括一第二框體220、一保護板250以及一第二液體230。詳細而言，第二框體220設置於導光板113的第二表面113c上。保護板250與第二 框體220連接，其中第二框體220與導光板113形成一第二容置空間RS2，且第二液體230配置於第二容置空間RS2內。更詳細而言，在本實施例中，第二液體230例如是填滿第二容置空間RS2。
舉例而言，在本實施例中，反射式顯示裝置200的製作 方法可更包括下列步驟。將第二框體220設置於導光板113的第二表面113c上，並設置保護板250。並使保護板250連接第二框體220。如此，可使第二框體220與導光板113形成第二容置空間RS2。接著，在本實施例中，第二框體220上亦具有至少一注入孔IH，而可將第二液體230注入至第二容置空間RS2內，以使第二液體230填滿第二容置空間RS2。更詳細而言，在本實施例中，導光板113與第二液體230的折射率比值亦介於1.02~1.20之間，但第一液體130與第二液體230的材質可相同或不同，本發明不以此為限。此外，在本實施例中，亦可於保護板250上選擇性地形成圖案化區域(未繪示)，以增加被反射至顯示單元140的照明光束60的光量。
如此一來，反射式顯示裝置200的前光模組110亦可提 供顯示單元140高亮度且均勻度良好的面光源111，且反射式顯示裝置200並仍可保有良好的顯示對比效果。換言之，反射式顯示裝置200亦達到與反射式顯示裝置100的作用，並具有類似的功效及優點，在此就不予贅述。
此外，上述的前光模組110的數量雖以一個為例示，但 本發明不以此為限。在其他的實施例中，前光模組110的數量亦 可為多個，以下將搭配圖3進行進一步解說。
圖3是本發明又一實施例的一種反射式顯示裝置的架構 示意圖。請參照圖3，在本實施例中，圖3的反射式顯示裝置300與圖1A的反射式顯示裝置100類似，而差異如下所述。具體而言，如圖3所示，在本實施例中，反射式顯示裝置300可為一可提供雙面顯示功能的反射式顯示裝置，至少一前光模組110為二前光模組110，且第一框體320連接二前光模組110的導光板113。換言之，在反射式顯示裝置300的製作方法的步驟中，於配置第一框體320時，可使第一框體320與二前光模組110的導光板113連接，以形成第一容置空間RS1。此外，在本實施例中，顯示單元340更可透過一固定構件FX固定於第一框體320上。
進一步而言，如圖3所示，在本實施例中，顯示單元340 為一雙面顯示單元，且顯示單元340包括一第一電極層341、二電泳顯示層343以及二第二電極層345。更詳細而言，第一電極層341位於二電泳顯示層343之間，第一電極層341包括多個第一電極EL1。這些第一電極EL1位於第一電極層341的兩側，且分別朝向二前光模組110的各第一表面113b。第二電極層345具有多個第二電極EL2，且各電泳顯示層343位於第一電極層341與其中一第二電極層345之間。
舉例而言，在本實施例中，電泳顯示層343可為微膠囊 電泳顯示層或是微杯電泳顯示層，為了方便說明，圖3僅以微膠囊電泳顯示層為例來說明，但本發明不以此為限。更詳細而言， 如圖3所示，在本實施例中，每一電泳顯示層343包括一顯示基質343a以及多個顯示粒子343b。顯示基質343a位於第一電極層341與第二電極層345之間，其中這些第二電極EL2位於第二電極層345面對顯示基質343a的一側。另一方面，電泳顯示層343將不同顏色(例如黑色與白色)的顯示粒子343b封裝於微膠囊結構中，且使這些顯示粒子343b分布於顯示基質343a中。此外，電泳顯示層343並可利用這些顯示粒子343b在各個微膠囊結構內部的分布來控制對外界光線的反射與否而達成顯示。如此一來，藉由此二電泳顯示層343的配置，將可使顯示單元340提供雙面顯示功能。
此外，在本實施例中，由於導光板113與第一液體130 的折射率比值亦介於1.02至1.20之間，因此反射式顯示裝置300的前光模組110亦可提供顯示單元340高亮度且均勻度良好的面光源111，且反射式顯示裝置300並仍可保有良好的顯示對比效果。換言之，反射式顯示裝置300亦達到與反射式顯示裝置100的作用，並具有類似的功效及優點，在此就不予贅述。
綜上所述，本發明的實施例的反射式顯示裝置及其製作 方法中，可藉由採用液態介面材料(即第一液體)來取代習知前光模組製程技術中使用的光學膠或是光學透明樹脂，而可簡化製程步驟與降低生產成本。此外，反射式顯示裝置並可透過控制導光板與第一液體的折射率比值介於1.02至1.20之間，以使反射式顯示裝置的前光模組可提供顯示單元高亮度且均勻度良好的面光 源，並仍保有良好的顯示對比效果。此外，反射式顯示裝置並可針對導光板的光學微結構的形狀進行設計，而可應用於大尺寸的顯示器或具有自由曲面的顯示器進而可不受限於顯示器的尺寸大小與形狀。
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，任何所屬技術領域中具有通常知識者，在不脫離本發明的精神和範圍內，當可作些許的更動與潤飾，故本發明的保護範圍當視後附的申請專利範圍所界定者為準。
