滤光组件30可设置于第一选择性光反射组件20(即第一液晶层20)上。在本申请的一些实施例中,滤光组件30也可称为“滤光层30”。在本申请的一些实施例中,第一选择性光反射组件20(即第一液晶层20)的第一胆固醇液晶23可朝滤光组件30(即滤光层30)的方向反射第一色光L1。
光吸收层40可设置于第一选择性光反射组件20(即第一液晶层20)的下方。光吸收层40可配置为吸收不被反射的光(包括例如不被第一选择性光反射组件20反射的光)。在本申请的一些实施例中,如图1及图2所示,光吸收层40可通过第一选择性光反射组件20(即第一液晶层20)与滤光组件30(即滤光层30)间隔开。
第二选择性光反射组件50可设置于第一选择性光反射组件20(即第一液晶层20)的上方。第二选择性光反射组件50可配置为反射第二色光L2。第二选择性光反射组件50可供第一色光L1穿透。在本申请的一些实施例中,第二选择性光反射组件50可包括第二胆固醇液晶53。因此,在本申请的一些实施例中,第二选择性光反射组件50也可称为“第二液晶层50”。在本申请的一些实施例中,如图1及图2所示,第二选择性光反射组件50(即第二液晶层50)可进一步包括导电基板(例如下导电基板)51、导电基板(例如上导电基板)52以及第二密封材54。第二胆固醇液晶53可设置于导电基板(例如下导电基板)51与导电基板(例如上导电基板)52之间。第二密封材54可围绕第二胆固醇液晶53。第二密封材54可与导电基板(例如下导电基板)51及导电基板(例如上导电基板)52共同密封第二胆固醇液晶53。在本申请的一些实施例中,导电基板(例如下导电基板)51可包括基材(例如下基材)511及电极层(例如下电极层)512。导电基板(例如上导电基板)52可包括基材(例如上基材)521及电极层(例如上电极层)522。在本申请的一些实施例中,基材(例如下基材)511及基材(例如上基材)521可为玻璃基材。电极层(例如下电极层)512可设置于基材(例如下基材)511(例如上表面)上。电极层(例如上电极层)522可设置于基材(例如上基材)521(例如下表面)上。在本申请的一些实施例中,电极层(例如下电极层)512及电极层(例如上电极层)522可包括但不限于氧化铟锡(Indium Tin Oxide,ITO)电极。在本申请的一些实施例中,第二选择性光反射组件50(即第二液晶层50)可通过电极层(例如下电极层)512与电极层(例如上电极层)522的电压差决定第二胆固醇液晶53的转向。在本申请的一些实施例中,第二胆固醇液晶53可旋转一角度或呈平行态样,以反射第二色光L2。当显示装置1欲显示黑色时,第二胆固醇液晶53可呈类似垂直态样,或称为焦点圆锥(Focal-conic)状态,而不反射第二色光L2。
在本申请的一些实施例中,第二选择性光反射组件50(即第二液晶层50)可设置于滤光组件30(即滤光层30)上,以使滤光组件30(即滤光层30)可位于或设置于第一选择性光反射组件20(即第一液晶层20)与第二选择性光反射组件50(即第二液晶层50)之间。在本申请的一些实施例中,滤光组件30(即滤光层30)可接触第一选择性光反射组件20(即第一液晶层20)。在本申请的一些实施例中,滤光组件30(即滤光层30)可接触导电基板22。在本申请的一些实施例中,滤光组件30(即滤光层30)可接触第二选择性光反射组件50(即第二液晶层50)。在本申请的一些实施例中,滤光组件30(即滤光层30)可接触导电基板51。在本申请的一些实施例中,第二选择性光反射组件50(即第二液晶层50)的第二胆固醇液晶53可朝相反于滤光组件30(即滤光层30)的方向反射第二色光L2。且在结构配置上,滤光组件30(即滤光层30)为位于第一胆固醇液晶23与第二胆固醇液晶53之间。
第二色光L2具有波长范围λ2。第二色光L2为显示装置1进行颜色显示时所需要的色光。在本申请的一些实施例中,第二色光L2的波长范围λ2可在数值上(包括例如波长范围上限值及波长范围下限值)小于第一色光L1的波长范围λ1。在本申请的一些实施例中,第二色光L2可包括但不限于蓝光、青光或绿光。
在本申请的一些实施例中,显示装置1可通过第一选择性光反射组件20(即第一液晶层20)反射的第一色光L1及第二选择性光反射组件50(即第二液晶层50)反射的第二色光L2进行各别或混合显示颜色。然而,当显示装置1仅以第一选择性光反射组件20(即第一液晶层20)反射的第一色光L1显示单色,且第三色光L3的波长范围λ3与第二色光L2的波长范围λ2重迭或实质相同时,第三色光L3会在大视角(例如可视角大于或等于140°)方向上与第一色光L1混光而导致所显示的单色纯度不足(即产生色偏)。
滤光组件30(即滤光层30)具有吸收光波长范围λa。在本申请的一些实施例中,滤光组件30(即滤光层30)的吸收光波长范围λa可与第三色光L3的波长范围λ3重迭或实质相同,以吸收第三色光L3,防止第三色光L3在大视角(例如可视角大于或等于140°)方向上对显示装置1的颜色显示造成干扰。
考虑上述显示的单色纯度不足(即产生色偏)的情况易发生在第三色光L3的波长范围λ3与第二色光L2的波长范围λ2重迭或实质相同时,滤光组件30(即滤光层30)的吸收光波长范围λa亦可与第二色光L2的波长范围λ2重迭或实质相同。另一方面,为使滤光组件30(即滤光层30)可供第一色光L1穿透(即不吸收第一色光L1),滤光组件30(即滤光层30)的吸收光波长范围λa与第一色光L1的波长范围λ1不重迭,以避
免第一色光L1被吸收。在本申请的一些实施例中,滤光组件30(即滤光层30)的吸收光波长范围λa可在数值上(包括例如波长范围上限值及波长范围下限值)小于第一色光L1的波长范围λ1。
在本申请的一些实施例中,滤光组件30(即滤光层30)可包括但不限于光学透明胶(optical clear adhesive,OCA)。光学透明胶(OCA)可吸收第三色光L3。光学透明胶(OCA)可供第一色光L1穿透(即不吸收第一色光L1)。
在图1及图2所示的实施例中,显示装置1通过设置滤光组件30(即滤光层30)于第一选择性光反射组件20(即第一液晶层20)与第二选择性光反射组件50(即第二液晶层50)之间,可有效吸收第一选择性光反射组件20(即第一液晶层20)反射的第三色光L3。在没有第三色光L3干扰的优势下,显示装置1在大视角(例如可视角大于或等于140°)方向上的显示颜色不会产生色偏,显示颜色的纯度因此得到提升。
本申请另以下列实施例及配合图2说明显示装置1通过第一选择性光反射组件20(即第一液晶层20)、滤光组件30(即滤光层30)及第二选择性光反射组件50(即第二液晶层50)进行颜色显示的操作。
