Description

一种显示面板及显示装置 技术领域
本申请涉及显示技术领域，具体涉及一种显示面板及显示装置。
 背景技术
液晶显示器（Liquid Crystal Display，LCD）因具有高画质、省电、机身薄、应用范围广、性能稳定和安全等优点，而被广泛的应用于车载、手机、电视、个人数字助理、数字相机、笔记本电脑、台式计算机等各种消费性电子产品，成为显示装置中的主流。
在车载显示器中，驾驶员状态监测系统（Driver Monitor System，DMS）能够对驾驶员的疲劳程度监测，提升驾驶安全性能，与此同时，DMS伴随着自动驾驶、车联网及相关技术逐渐的成熟逐步演进和迭代出了更多功能，并逐渐被用户所认可。为了满足DMS的监测需求，需要在液晶显示器上加装光学元件，该光学元件例如为摄像头，而为了尽量避免将摄像头直接暴露在用户视野范围而引起的误会，现有的配备DMS功能的液晶显示器多采用将摄像头隐藏在液晶显示面板的背面的解决方案，但该解决方案在解决摄像头暴露问题的同时，也使得摄像头在执行采光功能时，外界环境光需要至少穿过液晶显示面板后才能顺利射入到摄像头内，大大提升了摄像头采取外界环境光的难度，直接导致摄像头采光量不足、DMS成像效果较差的问题，此问题亟待解决。

图1示出了本申请实施例提供的显示面板的结构示意图，如图1所示，本申请实施例一提供一种显示面板10，所述显示面板10包括：第一基板100和第二基板200，所述第一基板100和所述第二基板200相对设置。所述显示面板10还包括设置于所述第一基板100和所述第二基板200之间的液晶层300，所述液晶层300中分布有液晶分子，所述液晶分子能够在驱动电场的作用下发生偏转。所述第一基板100和所述第二基板200在靠近所述液晶层300的一侧均设置有配向层，所述配向层能够为所述液晶分子提供均匀排列的接口条件，让所述液晶分子依照预定的顺序排列。
图2示出了本申请实施例提供的显示面板的俯视图，结合图1和图2所示，所述显示面板10包括：显示区11和透光区12，其中，所述显示面板10的显示区11设置有像素单元，并用于执行显示功能；所述显示面板10的透光区12具有透过光线的功能，也即所述透光区12的透光率高于所述显示区11的透光率，从而，当在所述显示面板10的一侧对应所述透光区12的位置设置光学元件时，所述光线能够顺利穿过所述显示面板10的透光区12，并入射到所述光学元件中，以使所述光学元件正常执行感光功能。
本实施例中，所述第一基板100上的所述配向层为第一配向层，所述第二基板200上的所述配向层为第二配向层，所述第一配向层和/或所述第二配向层在所述透光区12设置有缺口（图中未示出）。由于至少一个所述配向层在所述透光区12设置有缺口，从而能够有效减少配向层对穿透所述显示面板10透光区12的光线的过滤作用，减少光损失，提升显示面板10在透光区12的透光率。优选的，所述第一配向层和所述第二配向层在所述透光区12均设置有缺口，且所述第一配向层上的缺口与所述第二配向层上的缺口对应设置，本实施例通过在所述显示面板10的两个所述配向层上均设置缺口，从而能够进一步提升所述显示面板10在透光区12的透光率。
本实施例中，所述光线例如为940（±10）nm的红外光（Infrared，IR），所述透光率例如为红外光透过率，所述光学元件例如具有红外光感应功能，由于人体自身可以发出红外光，当位于所述显示面板10一侧且对应所述透光区12设置的光学元件采集所述红外光并成像时，能够在实现DMS的监测需求的同时，很好的保护用户隐私。
本实施例中，所述缺口内填充有光学膜材，且所述光学膜材的透光率大于所述配向层的透光率。通过在所述缺口内填充透光率更高的光学膜材，能够在提升所述显示面板10在透光区12的透光率的同时，填补所述配向层上的缺口，实现平坦化。
本实施例中，所述光学膜材的可见光反射率小于所述配向层的可见光反射率。由于所述学膜材的可见光反射率小于所述配向层的可见光反射率，从而能够提升所述显示面板10的均一化显示效果，提升显示质量。
本实施例中，所述光学膜材例如为减反增透膜，所述减反增透膜填充于所述配向层的缺口内。所述减反增透膜能够减少可见光在所述显示面板10中的反射率，增加红外光在所述显示面板10中的透过率。
继续参照图2，本实施例中，所述显示区11与所述透光区12间隔设置，所述显示面板10还包括过渡区13，所述过渡区13位于所述显示区11和所述透光区12之间的间隙区域，所述过渡区13的显示面板膜层结构不同于所述显示区11的显示面板膜层结构和所述透光区12的显示面板膜层结构，且所述配向层至少设置在所述显示面板10的过渡区13。相应的，由于位于所述显示区11和所述透光区12之间的间隙区域也设置有配向层，从而能够使得位于所述显示区11和所述过渡区13的交界区域附近的液晶分子，具有与位于所述显示区11的液晶分子相同的配向形态，保证所述显示区11的显示效果。
本实施例中，所述过渡区13围绕所述透光区12，所述显示区11围绕所述过渡区13。
本实施例中，所述显示面板10例如还包括非显示区，所述非显示区与所述显示区11相邻接，且所述非显示区围绕所述显示区11设置。

本实施例中，所述配向层包括设置于所述第一基板100上的第一配向层160和设置于所述第二基板200上的第二配向层280，所述第一配向层160在所述透光区12设置有第一缺口161，所述第二配向层280在所述透光区12设置有第二缺口281，所述第一缺口161的面积与所述第二缺口281的面积相同。
本实施例中，所述第一基板100包括：第一衬底基板110，所述第一衬底基板110为所述第一基板100上的其他膜层结构的载体，其可以为刚性基板或柔性基板，其材质可以是玻璃、塑料或其他透光性优良的无机或有机材料。优选的，所述第一衬底基板110为刚性玻璃基板。
本实施例中，所述第一基板100还包括设置于所述第一衬底基板110上的黑矩阵层120，所述黑矩阵层120位于所述显示区11，也即所述透光区12未设置所述黑矩阵层120。由于所述透光区12省去了透光率较低的黑矩阵层120，从而能够进一步提升所述显示面板10的透光率。具体的，位于所述显示区11的黑矩阵层120形成有网格状的黑矩阵结构121，所述黑矩阵结构121的红外光透过率为0%，由于所述第一基板100在所述透光区12并未设置黑矩阵结构121，从而能够大大提高所述透光区12的红外光透过率。进一步的，所述黑矩阵结构121包括位于所述显示区11和所述过渡区13的边界的黑矩阵环1211，也即所述黑矩阵环1211为所述显示区11和所述过渡区13的分界线。
本实施例中，所述第一基板100还包括依次层叠设置于所述黑矩阵层120上的彩膜层130和第一平坦层140，所述彩膜层130位于所述显示区11、过渡区13和透光区12，所述第一平坦层140位于所述显示区11、过渡区13和透光区12，且所述透光区12的所述第一平坦层140的厚度大于所述显示区11的所述第一平坦层140的厚度。具体的，位于所述显示区11、过渡区13和透光区12的彩膜层130为同道工艺制作形成，所述显示区11的彩膜层130包括多种颜色的色阻单元，所述色阻单元用于实现彩色显示功能；位于所述显示区11、过渡区13和透光区12的第一平坦层140为同道工艺制作形成，所述第一平坦层140远离所述第一衬底基板110的表面为一平整面，用于实现平坦化功能。所述彩膜层130的红外光透过率为98%，所述第一平坦层140的红外光透过率为100%，由于所述彩膜层130和所述第一平坦层140的红外光透过率均较高，因此，在所述显示区11和所述透光区12均保留有所述彩膜层130和所述第一平坦层140。
本实施例中，所述第一基板100还包括设置于所述第一平坦层140上的第一配向层160，所述第一配向层160位于所述显示区11和所述过渡区13，所述第一配向层160在所述透光区12设置有所述第一缺口161，所述第一缺口161的边缘位于所述透光区12和所述过渡区13的边界，也即所述第一配向层160形成所述第一缺口161的边缘为所述过渡区13和所述透光区12的分界线。所述第一配向层160的红外光透过率为92%，由于所述第一配向层160在所述透光区12缺失，从而能够大大提高所述透光区12的红外光透过率。
本实施例中，所述第一基板100还包括填充于所述第一缺口161内的第一光学膜材170，所述第一光学膜材170的透光率大于所述第一配向层160的透光率。由于所述第一基板100在对应所述透光区12的区域形成有透光率更高第一光学膜材170，从而能够有效提升所述显示面板10在透光区12的红外光透过率。
本实施例中，所述第一光学膜材170的可见光反射率小于所述第一配向层160的可见光反射率，通过降低所述第一光学膜材170的可见光反射率，能够提升所述显示面板10的均一化显示效果，改善显示面板10的显示质量。
本实施例中，所述第一光学膜材170例如为减反增透膜，所述减反增透膜填充于所述第一配向层160的第一缺口161内。所述减反增透膜能够减少可见光在所述显示面板10中的反射率，增加红外光在所述显示面板10中的透过率。
本实施例中，所述第一基板100还包括设置于所述第一配向层160和所述第一平坦层140之间的支撑柱层150，所述支撑柱层150包括间隔设置的多个支撑柱，所述支撑柱能够使所述第一基板100和所述第二基板200之间形成一稳定的间隔距离，保证显示面板10的正常显示。具体的，所述多个支撑柱位于所述显示区11，也即所述支撑柱未设置在所述透光区12，由于支撑柱会对红外光产生衍射，进而影响位于显示面板一侧的光学元件的成像效果，而本申请在所述透光区12未设置所述支撑柱，从而能够在进一步提升所述显示面板10在透光区12的红外光透过率的同时，避免衍射现象，提升所述光学元件的成像效果。
本实施例中，所述第二基板200包括：第二衬底基板210和设置于所述第二衬底基板210上的薄膜晶体管层，所述薄膜晶体管层包括薄膜晶体管和金属走线，所述薄膜晶体管位于所述显示区11和所述过渡区13；所述金属走线位于所述显示区11和所述过渡区13。也即，所述透光区12未设置所述薄膜晶体管和所述金属走线，薄膜晶体管和金属走线一般包括不透光的金属材料，由于所述透光区12未设置所述薄膜晶体管和金属走线，从而能够进一步提升所述显示面板10在透光区12的红外光透过率。
本实施例中，所述薄膜晶体管例如为低温多晶硅（LTPS）薄膜晶体管，所述薄膜晶体管层包括多种膜层，所述多种膜层例如包括依次层叠设置在所述第二衬底基板210上的遮光层、缓冲层、第一金属层、栅极绝缘层、有源层、层间介质层220和第二金属层。其中，所述遮光层包括与所述有源层的沟道区对应设置的遮光图案，所述遮光层位于所述显示区11和所述过渡区13；所述缓冲层为氮化硅膜层与氧化硅膜层形成的叠层结构，所述缓冲层位于所述显示区11、过渡区13和透光区12；所述第一金属层包括栅极和金属走线，所述第一金属层位于所述显示区11和所述过渡区13；所述栅极绝缘层为氧化硅膜层，所述栅极绝缘层位于所述显示区11、过渡区13和透光区12；所述有源层包括沟道区、重掺杂区和轻掺杂区，所述有源层位于所述显示区11和所述过渡区13；所述层间介质层220为氮化硅膜层与氧化硅膜层形成的叠层结构，所述层间介质层220位于所述显示区11、过渡区13和透光区12；所述第二金属层包括源极、漏极和金属走线，所述第二金属层位于所述显示区11和所述过渡区13。当然，本申请实施例对所述薄膜晶体管的类型并不作限制，所述薄膜晶体管的类型还可以是非晶硅薄膜晶体管或氧化物薄膜晶体管。

不同的是，本申请实施例二提供的显示面板10中的层间介质层220位于所述显示区11和过渡区13，也即所述层间介质层220未设置在所述透光区12，从而简化了所述透光区12的膜层结构，减少了膜层数量，能够进一步提升所述显示面板10在透光区12的红外光透过率。
