附图说明
图1为本公开的一些实施例的光源分色装置的结构示意图；
图2为本公开的一些实施例的显示装置的结构示意图。
其中附图标记为：1、锯齿单元；2、发光单元；3、像素单元。
具体实施方式
为使本领域技术人员更好地理解本公开的技术方案，下面结合附图和具体实施方式对本公开作进一步详细描述。
结合图1所示，本实施例的一些提供一种光源分色装置，其包括多个锯齿单元1以及发光单元2；其中，多个锯齿单元1呈阵列排布；每个所述锯齿单元1包括多个锯齿，任意两相邻的所述锯齿单元1中的所述锯齿的工作面与底面的夹角的大小不同；发光单元2能够按照一定入射角度向所述锯齿的工作面上照射平行光，以使照射至任意两相邻的所述锯齿单元1的锯齿工作面上，经过反射衍射出的光的颜色不同。在此需要说明的是，本公开的一些实施例的各个锯齿单元可以形成在基底上，也可以是形成为一体的结构。
不难看出的是，本公开的一些实施例中的多个锯齿单元1构成了相关技术中的中阶梯光栅(又称反射式阶梯光栅)，在本公开的一些实施例中，利用中阶梯光栅的色散特性，将发光单元2所发射出来的光，经过反射衍射出其它颜色的光。
具体的，假若想得到红、绿、蓝三种不同颜色的光，发光单元2发所发出的光为白光，根据中阶梯光栅方程mλ＝2dsinθ，其中，m为衍射级次，λ为衍射波长，d为光栅常数，θ为闪耀角(闪耀角即为锯齿的工作面与底面的夹角)，此时发光单元2所发出来的白光则可以根据闪耀角θ衍射出一种波长的光，而一种波长的光则代表一种颜色的光，对于本领域技术人员而言，红、绿、蓝三种不同颜色的光所对应的波长是可知的，因此可以预先设计出与这三种波长对应的闪耀角θ的大小，也就是图1中所示，各个锯齿单元中闪耀角θ1、θ2、θ3，以使发光单元2所发出的白光照射至相应锯齿的工作面后可以反射衍射出相应颜色的光，即闪耀角θ1对应反射衍射出红光R；闪耀角θ2对应反射衍射出绿光G；闪耀角θ3对应反射衍射出蓝光B。
综上所述，本公开的一些实施例中的光源分色装置，通过发光单元2按照 一定入射角度向所述锯齿的工作面上照射平行光，光照射至各锯齿单元1的锯齿的工作面上，反射光符合光的反射定律，并在工作面上方发射衍射，产生色散；同时通过控制闪耀角θ的大小，实现对衍射光谱中心强度的控制，以分散出相应颜色的光，达到光的分色的同时，省略显示装置中彩膜的设计，从而达到降低成本和提高产能的效果。
其中，发光单元2可以为准直平行光源，设置在基底和锯齿单元1的侧边位置，当然无论准直平行光源设置在哪，只要能够向各个锯齿的工作面照射平行光即可。本实施例中的准直平行光源可以由LED灯组构成。
其中，本公开的一些实施例中发光单元2所发出的光为白光，此时，通过可以将各个锯齿单元1中的闪耀角的大小设计成与红、绿、蓝三种不同颜色的光对应的角度，以达到显示装置的全彩色显示。当然，发光单元2所发出的光颜色也不局限于白光，可以根据具体需要而设定。
其中，本公开的一些实施例中的各个锯齿的材料可以选用金属铝，也可以采用其他具有发射性能的金属材料。当然，各个锯齿的材料也可以采用石英，此时需要在各个所述锯齿的工作面上均设置有反射层，用于将所述发光单元2照射至所述锯齿上的光进行反射。需要说明的是，在本公开的一些实施例中，并不对锯齿的材料进行限定，可以选用任何符合上述条件的材料。
本公开的一些实施例中所提供的光源分色装置，利用中阶梯光栅的分色原理，将发光单元2所发出的光分色出不同颜色的光，将这种光源分色装置作为背光源应用至显示装置中，此时显示装置中无需彩膜，因此可以降低成本和提高产能。
结合图2所示，本公开的一些实施例提供一种显示装置，其包括上述光源分色装置，因此，显示装置中无需彩膜，因此可以降低成本和提高产能。
其中，本公开的一些实施例中的显示装置还包括显示模组，其设置在光源分色装置出光面侧，显示模组包括呈矩阵设置像素单元3，所述像素单元3与所述锯齿单元1相对应设置，从而实现显示装置的全彩色显示。
本公开的一些实施例中显示装置的显示模组可以包括相对设置的阵列基板和对盒基板，也就是说无需设置彩膜，当然如果将对盒基板替换成彩膜基板也是可以的，这样可以增加显示装置的色彩度，提高显示效果。
其中，显示装置可以为液晶显示装置或者电致发光显示装置，例如液晶面 板、电子纸、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
可以理解的是，以上实施方式仅仅是为了说明本公开的原理而采用的示例性实施方式，然而本公开并不局限于此。对于本领域内的普通技术人员而言，在不脱离本公开的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本公开的保护范围。
