具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
参见图1，本发明实施例提供了一种彩膜基板10，该彩膜基板10包括：第一基板11和形成于第一基板11的第一表面11a上的彩膜层12。其中，第一表面为第一基板11上的任一主要表面。参见图2，彩膜层12上周期性地分布着多种透射图形P，每种透射图形由一种孔径范围的波长孔H周期性排布构成，且每种透射图形P透射一种颜色的光。
本发明实施例提供的彩膜基板中，彩膜层上周期性地分布有多种透射图形，每种透射图形能够透射一种颜色的光，这样，当背光源发出的光经过该彩膜层后，不同颜色的光经过具有不同孔径范围的波长孔透射，使得每种颜色的光都具有很好的透过率，从而提高了显示效果。
在图1所示的彩膜基板的结构基础上，本发明另一实施例提供了一种彩膜基板，该彩膜基板10中的彩膜层12可以为由金属材料构成的金属层，该金属材料可以包括铝、金、银、铂、铜、镍、钯、锌、铁和铬等中的至少一种。由金属材料制作的彩膜层12为一种等离激元的彩膜(Plasmonic  CF)，不仅具有很高的反射率，从而具有良好的镜子显示功能，而且能够利用金属表面的等离子体激元共鸣效应，实现不同孔径范围的波长孔透射不同颜色的光。
作为一种可选的实施例，彩膜层12的厚度一般可以为100nm～300nm。
作为一种可选的实施例，透射图形上的波长孔H的形状为圆形和/或正多边形。在图示的实施例中，波长孔H的形状为圆形。
作为一种可选的实施例，如图3所示，多种透射图形可以包括红光透射图形P1、蓝光透射图形P3和绿光透射图形P2等，每种透射图形能够透射一种颜色的光，例如，红光透射图形能够透射红光，蓝光透射图形能够透射蓝光，绿光透射图形能够透射绿光。由于不同颜色的光波长不同，相应地，每种颜色的光从透视图形的波长孔中透射所需要的孔径范围是不同的，一般情况下，红光透射图形P1中的波长孔H1的孔径范围最大，绿光透视图形P2中的波长孔H2的孔径范围相对红光透射图形P1中的波长孔H1的孔径范围要小，蓝光透射图P3形中的波长孔H3的孔径范围最小。在本实施例中，构成红光透射图形P1的波长孔H1的孔径范围为400nm～470nm，构成绿光透射图形P2的波长孔H2的孔径范围为280nm～310nm，构成蓝光透射图形P3的波长孔H3的孔径范围为200nm～270nm。图3示出了彩膜层12上不同透射图形的示意图，左侧的透射图形为红光透射图形P1，中间的透视图形为绿光透射图形P2，右侧的透射图形为蓝光透射图形P3。
作为一种可选的实施例，为了防止透射图形上的波长孔被破坏，如图3a所示，彩膜层12上还可设置有一层保护层13，例如，该保护层可以为 氧化硅层。
本发明实施例提供的彩膜基板中，彩膜层上周期性地分布有多种透射图形，每种透射图形能够透射一种颜色的光，这样，当背光源发出的光经过该彩膜层后，不同颜色的光经过具有不同孔径范围的波长孔透射，使得每种颜色的光都具有很好的透过率，从而提高了显示效果。
需要注意的是，本发明各个实施例提供的彩膜基板，除了包括前述的第一基板11和彩膜层12之外，必然还包括作为彩膜基板的必要组成部分的各种元件和层结构，如光阻等，然而，为了清楚的目的，省略这些元件和层结构的描述和说明。
参见图4，本发明实施例提供了一种显示装置，该显示装置包括图1所示的彩膜基板10、液晶盒20及背光源30。其中，彩膜基板10设置于液晶盒20与背光源30之间。
在实际应用中，该显示装置可以为液晶显示面板、智能手机、平板电脑、智能电视、台式电脑、数码相框机导航仪等任何具有显示功能的产品或部件。
本实施例提供的显示装置中，彩膜基板的彩膜层上周期性地分布有多种透射图形，每种透射图形能够透射一种颜色的光，这样，当背光源发出的光经过该彩膜层后，不同颜色的光经过具有不同孔径范围的波长孔透射，使得每种颜色的光都具有很好的透过率，从而提高了显示效果。
在图4所示的显示装置的基础上，本发明另一实施例提供了一种显示 装置，如图5所示，该显示装置中的液晶盒20包括第二基板21、第三基板22、第一电极层23、第二电极层24及液晶层25。参见图5，第一电极层23设置于第三基板22朝向第二基板21的表面上，第二电极层24设置于第二基板21朝向第三基板22的表面上，液晶层25设置于第一电极层23和第二电极层24之间。

作为一种可选的实施例，第一电极层23和第二电极层24可以为透明电极层。
作为一种可选的实施例，液晶层25可以由负性液晶、可聚合单体和光引发剂等组成。根据液晶和高分子折射率的差异，在不施加电压的情况下，液晶层25为透明态，可作为透明的功能膜材料；在施加电压的情况下，液晶层25为非透明态，可作为一种不透明的功能膜材料。
图5所示的显示装置工作原理如下：
在不施加电压的情况下，背光源30处于关闭状态，液晶层25处于透明状态，彩膜基板10上的彩膜层12能够反射环境光，呈现镜子功能；在施加电压的情况下，背光源30发出的光经过彩膜层12透射出不同颜色的光，且所透射的光经过液晶层25对透过率的控制，从而实现良好的显示效果。
本实施例提供的显示装置中，彩膜基板的彩膜层上周期性地分布有多种透射图形，每种透射图形能够透射一种颜色的光，这样，当背光源发出的光经过该彩膜层后，不同颜色的光经过具有不同孔径范围的波长孔透射， 使得每种颜色的光都具有很好的透过率，从而提高了显示效果。

作为一种可选的实施例，第一电极层23和第二电极层24可以为透明电极层。
作为一种可选的实施例，液晶层25可以由负性液晶、可聚合单体和光引发剂等组成。根据液晶和高分子折射率的差异，在不施加电压的情况下，液晶层25为透明态，可作为透明的功能膜材料；在施加电压的情况下，液晶层25为非透明态，可作为一种不透明的功能膜材料。
图6所示的显示装置工作原理如下：
在不施加电压的情况下，背光源30处于关闭状态，液晶层25处于透明状态，彩膜基板10上的彩膜层12能够反射环境光，呈现镜子功能；在施加电压的情况下，背光源30发出的光经过彩膜层12透射出不同颜色的光，且所透射的光经过液晶层25对透过率的控制，从而实现良好的显示效果。
本实施例提供的显示装置中，彩膜基板的彩膜层上周期性地分布有多 种透射图形，每种透射图形能够透射一种颜色的光，这样，当背光源发出的光经过该彩膜层后，不同颜色的光经过具有不同孔径范围的波长孔透射，使得每种颜色的光都具有很好的透过率，从而提高了显示效果。
在图4所示的显示装置的基础上，本发明另一实施例提供了一种显示装置，如图7所示，该显示装置中的液晶盒20包括第一基板11、绝缘层26、第二基板21、第一电极层23、第二电极层24及液晶层25。参见图7，绝缘层26设置于位于第一基板11的第一表面11a上的彩膜层12上，第一电极层23设置于绝缘层26上，第二电极层24设置于第二基板21朝向第一基板11的表面上，液晶层25设置于第一电极层23与第二电极层24之间。

作为一种可选的实施例，液晶层25可以由负性液晶、可聚合单体和光引发剂等组成。根据液晶和高分子折射率的差异，在不施加电压的情况下，液晶层25为透明态，可作为透明的功能膜材料；在施加电压的情况下，液晶层25为非透明态，可作为一种不透明的功能膜材料。
图7所示的显示装置工作原理如下：
在不施加电压的情况下，背光源30处于关闭状态，液晶层25处于透明状态，彩膜基板10上的彩膜层12能够反射环境光，呈现镜子功能；在施加电压的情况下，背光源30发出的光经过彩膜层12透射出不同颜色的光，且所透射的光经过液晶层25对透过率的控制，从而实现良好的显示 效果。
本实施例提供的显示装置中，彩膜基板的彩膜层上周期性地分布有多种透射图形，每种透射图形能够透射一种颜色的光，这样，当背光源发出的光经过该彩膜层后，不同颜色的光经过具有不同孔径范围的波长孔透射，使得每种颜色的光都具有很好的透过率，从而提高了显示效果。
需要注意的是，本发明各个实施例提供的显示装置，除了包括前述的彩膜基板10、液晶盒20和背光源30之外，必然还包括作为显示装置的必要组成部分的各种元件和层结构，如阵列基板等，然而，为了清楚的目的，省略这些元件和层结构的描述和说明。
