Description

一种显示面板及其显示器件 技术领域
本发明涉及平面显示领域，尤其是，一种可用于OLED、LCD等面显示器件上的显示面板。
 背景技术
已知，QD (Quantμm Dots, 量子点)材料由于拥有较宽的吸收峰和较窄的发射峰，使其在颜色显示上可以表现更高的纯度，从而使得其用到显示器件中时，可以提升显示器件的显示效果。例如，将其应用到LCD中时，其可以有效提升LCD的色域，从而能够增加LCD面板的竞争力。
但是，在具体的实施上却还有很多问题需要攻克。其中一项就是解决量子点色阻（QD Color Filter）的混色和光利用率低的问题。
所谓的混色问题就是，如图2所示，显示器件的基板100的OC(Over Coating，光刻胶)层102上通常会并排设置多个不同颜色的量子点色阻110，每一色阻只能射出一种颜色的光，其一般分别是红、绿、蓝三种颜色的光。其中相邻两色阻之间发出的光，因光发射角度问题，会射入相邻的色阻内。虽然所述色阻110上方设置的BM层120会起到一定的阻挡作用，但如图中箭头线所示，还是会有光线射入到临近的色阻110内，从而出现两种颜色光的混色问题。
相应的，各色阻中的量子点被激发后发出的光从所在色阻中射出后，不会在返回到色阻内，从而也不会再次激发色阻内的量子点，使其再次被激发而发光，如此，导致其光利用率比较低。
因此，确有必要来研发一种新型的显示面板，来克服现有技术中的缺陷。
 技术问题
本发明的一个方面是提供一种显示面板，其能够有效解决现有技术中存在的混色和光利用率低的问题。
 技术解决方案
本发明采用的技术方案如下：
一种显示面板，包括基板。其中所述基板上设置有彩膜层，所述彩膜层包括第一色阻和第二色阻，其中所述第一色阻内设置有第一颜色的量子点，所述第二色阻内设置有第二颜色的量子点。其中所述彩膜层还包括反射色阻，所述反射色阻位于第一色阻和第二色阻之间；其中所述反射色阻与所述第一色阻和第二色阻的接触面的反射率>70%。
进一步的，在不同实施方式中，其中所述反射色阻与所述玻璃层的接触面的遮光系数OD>3/μm。
进一步的，在不同实施方式中，其中所述反射色阻的厚度在3~8μm。
进一步的，在不同实施方式中，其中所述反射色阻的上表面在竖直向高过所述第一色阻和第二色阻的上表面；其中所述反射色阻的下表面在竖直向低过所述第一色阻和第二色阻的下表面。
进一步的，在不同实施方式中，其中所述彩膜层还包括第三色阻，其与所述第二色阻之间也设置有反射色阻，其中所述第三色阻内设置有第三颜色的量子点。
进一步的，在不同实施方式中，其中所述彩膜层还包括第三色阻，所述第三色阻、所述第二色阻与所述第一色阻三者之间都设置有所述反射色阻。
进一步的，在不同实施方式中，其中所述第一色阻的第一颜色为红色；所述第二色阻的第二颜色为绿色，所述第三色阻的第三颜色为蓝色。
进一步的，在不同实施方式中，其中所述第一色阻与第二色阻上设置有蓝光遮光层。
进一步的，在不同实施方式中，其中所述反射色阻的上表面与所述玻璃层之间设置有BM层。
进一步的，本发明的又一实施方式提供了一种显示器件，其包括本发明涉及的所述显示面板。
 有益效果
本发明涉及的一种显示面板，其在不同色阻之间设置具有高遮光率和高反射性的反射色阻，通过所述发射色阻对于入射光的高反射性和高遮光性，使得入射光能够被反射回所在色阻进而再次激发其内的量子点再次发光，从而提高光的利用率，相应的也就减小了功耗；同时，未被反射回的入射光则被所述反射色阻所遮挡，以避免其穿过所述反射色阻入射到相邻不同颜色的色阻内，造成混色问题。
 附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明一个实施方式中涉及的一种显示面板的结构示意图；
图2为现有技术中显示面板的结构示意图。
 本发明的实施方式
以下将结合附图和实施例，对本发明涉及的一种显示面板及其显示器件的技术方案作进一步的详细描述。
请参阅图1所示，本发明的一个实施方式提供了一种显示面板，包括依次设置的蓝光背光模组20、偏光片22、基板10、OC层12、彩膜层和玻璃层24。
其中所述彩膜层包括间隔设置的第一色阻14、第二色阻16和第三色阻18，这些色阻中分别设置与其颜色对应的量子点，其激发后发出的光，例如，可以分别是红、绿、蓝三种颜色。
进一步的，每两相邻的色阻之间均设置有反射色阻用于竖直向隔开所述两相邻的色阻，如图中所示，所述第一反射色阻11、第二反射色阻13、第三反射色阻15以及第四反射色阻17之间设置有所述三个色阻。
具体的，在一个所述彩膜层的实施制程中，其为先进行所述多个反射色阻的材料涂布，其中所述反射色阻为负性光阻，其主要成分是高分子，具体可以是，树脂材料，包括但不限于酚醛树脂，含有不饱合乙烯基或甲基乙烯基的高分子树脂等等。进一步的，其选用材料内部还可以混有金属粒子，例如，金属铝，添加后所述反射色阻的整体颜色为近白色。
然后进行抽真空、预烘烤步骤以消除过多的溶剂，之后进行曝光以及显影步骤，将曝光过程中所使用的掩模板上的图案转印到涂布的所述负性光阻表面，进而最终形成所述的多个间隔设置的反射色阻。
其中这些间隔设置的不同反射色阻优选相同的材料，但不限于。在一个实施方式中，这些反射色阻共同选用的是一种具有高遮光系数和高反射性能的材料，其中所述的遮光系数（Optical Density, OD）可以是OD >3/μm，其中，OD值优选为4/μm或4.2/μm，所述高反射率最低要求可以是>70%，优选为>80%及以上。进一步的，其中所述反射色阻的厚度可以在3~8μm，具体厚度选择可随需要而定，并无限定。
进一步的，在所述多个反射色阻形成之后，依次在两反射色阻之间进行所述第一色阻、第二色阻和第三色阻的制备。分开依次制备是因为第一色阻、第二色阻和第三色阻选用材料不同，例如，其通常分别为R型色阻、G型色阻以及B型色阻，因此需要分别制备。
以第一色阻的制备为例，其为先进行构成材料的涂布，其选用的材料也为负性光阻，一般为树脂材料；然后经过抽真空和预烘烤消除过多的溶剂后，在通过曝光和显影步骤完成所述第一色阻的制备。所述第二色阻和第三色阻的形成制程与所述第一色阻的制程类似，为避免不必要的重复，此处不再赘述。
进一步的，为保证所述反射色阻能很好的反射其相邻色阻发出的各个角度的入射光，所述反射色阻在竖直向优选高出并低于其相邻色阻。如图中所示，第一色阻14周围或两侧设置的第三反射色阻15和第一反射色阻11，两反射色阻11、15的上表面在竖直向高于所述第一色阻14，其下表面低于所述第一色阻14的下表面。所述第二色阻16和第三色阻18也是同样的设置，为避免不必要的重复，此处不再赘述。
使用时，所述蓝光背光模组20发出的蓝光向上穿过所述偏光片22、基板10、OC层12进入各色阻，并激发其内的量子点使其发光。在本实施方式中，所述第一色阻14内的量子点激发后发出的光是红光，所述第二色阻16内的量子点激发后发出的光是绿光，所述第三色阻18内的量子点激发后发出的光是蓝光。相应的，所述第一色阻14、第二色阻16上均设置有蓝光遮光层142、162，用以遮挡多余的蓝光，以防止其射出色阻外，造成不必要的瑕疵。
如图中所示，由于所述每一色阻的周围均设置有本发明涉及的所述反射色阻，因此，这些色阻内的量子点被激发后发出的向周围方向的光均会被所述反射色阻反射回各自的色阻内，从而能够对其内的其他量子点进行再次激发，如此即提高了光的利用率，又相应的减小了功耗；同时，未被反射回的光则被所述反射色阻所遮蔽，以避免其穿过所述反射色阻入射到相邻不同颜色的色阻内，造成混色问题。
进一步的，所述反射色阻与所述玻璃层24相接的表面，为了更好的显示效果，两者之间可以设置一层BM（black matrix）层，以避免自所述玻璃层24之外的入射光经过所述玻璃层24之后被所述反射色阻反射回；或者对所述反射色阻的上表面进行粗糙化处理，以降低其表面的反射性能。
本发明的技术范围不仅仅局限于上述说明中的内容，本领域技术人员可以在不脱离本发明技术思想的前提下，对上述实施例进行多种变形和修改，而这些变形和修改均应当属于本发明的范围内。
