Description

一种显示面板 技术领域
本发明涉及显示领域，尤其涉及一种显示面板。
 背景技术
有机发光二极管（Organic Light Emitting Diode, OLED）显示技术与传统的液晶显示方式不同，无需背光灯，采用非常薄的有机材料涂层和玻璃基板，当有电流通过时，这些有机材料就会发光。OLED显示屏幕可以做得更轻更薄，OLED技术发展可视角度更大，并且可以显著地节省电能。
在当今全面屏的风潮之下，虽然各手机厂商提出了各式各样的解决方案，但正面开孔始终是无法解决的难题。于是，刘海屏、水滴屏、升降摄像头等设计方案才层出不穷，为了实现真正的全面屏，当下各家都在积极研发屏下摄像头技术。
魅族在申请的相关专利（CN107734102）中，就是把摄像头做到屏幕下方，利用了石墨烯屏幕特别透明的性质，把摄像头放在了屏幕下边；三星在公布的一项屏下摄像头专利（WO2017126863）中，前置摄像头将直接设计在印刷电路板上，并通过显示屏上的一个镜头孔来拍摄画面，但正面屏幕的覆盖面积将保持不变。除了前置摄像头之外，包括麦克风、指纹扫描仪、摄像头和透明天线等智能手机标准配备的一些传感器和零部件，都将位于前面板玻璃的下方。
虽然柔性OLED屏的衬底本身就是一个“透明的塑料”，但是如果把摄像头放到OLED屏下，并且能够得到很好的成像，那么屏幕的透光率至少也需要80%以上，然而目前的技术只能做到40%左右。即使可以成像，也会出现“纱窗效应”，除非大幅度降低摄像头上方的屏幕的像素区域密度。

每三个不同颜色的子像素构成一个像素单元，每个像素单元的像素区域密度相同，所述像素区域密度是指在单位面积内存在的像素单元的数量。其中，第一显示区100内第一子像素10的像素区域密度与第二显示区200内第二子像素20的像素区域密度相同，这样当第一显示区100用于显示时，第一显示区100和第二显示区200同时显像，且第一显示区100与第二显示区200保持相同的屏幕分辨率。
当第一子像素10与第二子像素20的色彩相同时，第一子像素10的面积小于或等于第二子像素20的面积。例如，当第一显示区100的蓝色子像素111的面积小于第二显示区200的蓝色子像素111的面积时，第一显示区100内第一像素间隙大于第二显示区200内第二像素间隙，所述的像素间隙指的是两个相邻的子像素间的距离；因为准直器30设于第一像素间隙中，所以当第一显示区100用于拍摄时，第一显示区100具有良好的透光性。优选地，第一显示区100的蓝色子像素111以及红色子像素121的面积小于第二显示区200的蓝色子像素111以及红色子像素121的面积时，准直器30设于第一像素间隙中。其中，两个以上准直器30被排列在至少一条直线上；或者两个以上准直器30被排列为矩阵；或者两个以上准直器30均匀分布于第一显示区100内。
如图1所示，第一显示区100的蓝色子像素111以及红色子像素121的面积小于第二显示区200的蓝色子像素111以及红色子像素121的面积时，多个准直器30被设置在蓝色子像素111与红色子像素121之间，且两个以上准直器30被排列在至少一条直线上。当第一显示区100用于显示时，第一显示区100和第二显示区200同时显像，且第一显示区100与第二显示区200保持相同的屏幕分辨率；当第一显示区100用于拍摄时，第一显示区100具有良好的透光性。
如图2所示，第一显示区100的蓝色子像素111以及红色子像素121的面积小于第二显示区200的蓝色子像素111以及红色子像素121的面积时，多个准直器30被设置在蓝色子像素111与红色子像素121之间，且两个以上准直器30被排列在至少一条直线上。当第一显示区100用于显示时，第一显示区100和第二显示区200同时显像，且第一显示区100与第二显示区200保持相同的屏幕分辨率；当第一显示区100用于拍摄时，第一显示区100具有良好的透光性。
如图3所示，第一显示区100的蓝色子像素111以及红色子像素121的面积小于第二显示区200的蓝色子像素111以及红色子像素121的面积时，多个准直器30被设置在四个子像素的间隙中，准直器30被排列为矩阵，当光线从各个方向照射进来聚集在第一显示区时，可以提高入光量。当第一显示区100用于显示时，第一显示区100和第二显示区200同时显像，且第一显示区100与第二显示区200保持相同的屏幕分辨率；当第一显示区100用于拍摄时，第一显示区100具有良好的透光性。
准直器30为透明材质，准直器30可以保证光线通过准直器射出的光线平行，从而避免了在拍照过程中，因干涉或者衍射而对拍照对象的识别带来影响；另外，准直器30的俯视图面优选为曲线多边形，但是也可以为菱形、圆形、矩形、正多边形，在此不做限定。曲线多边形，可以是具有凹凸的结构或者是弧形结构围堰形成的图形，类似花瓣形，只要能将第一像素间隙尽可能地完全填充即可，进而减少散射，提高入光量；本实施例中的俯视面是指从显示面板的上方向下方做正投影得到的视图。
如图4所示，显示面板包括基板1、薄膜晶体管层2、像素定义层3、发光层4、第一无机层51、有机层6、第二无机层52、触控层7、偏光片8、盖板9、通孔101、凹槽102以及感光传感器103。
基板1的材料主要为聚酰亚胺（Polyimide, PI），PI材料可以有效地提高透光度。
薄膜晶体管层2设于基板1的上表面。其中，薄膜晶体管层2包括缓冲层21、有源层22、第一栅极绝缘层231、第一栅极电极241、第二栅极绝缘层232、第二栅极电极242、介电层25、源漏电极26、平坦层27以及阳极28。每一个有源层22以及有源层22对应的第一栅电极241、第二栅极层242以及源漏极26等形成一个薄膜晶体管201。具体地，在基板1上形成一层缓冲层21，缓冲层21所用材料为氮化硅、氧化硅或氮氧化硅中的一种；有源层22设于缓冲层21上；第一栅极绝缘层231设置在缓冲层21及第一栅极电极241之间，第一栅绝缘层231主要是使第一栅极电极241起到绝缘的作用；第二栅极绝缘层232设于第一栅极电极241与第二栅极电极242之间，以隔绝第一栅极电极241与第二栅极电极242电连接导致短路；源漏电极26设置在缓冲层21上，源极起到集电的作用，漏极起到发射的作用；介电层25与第二栅极电极连接，且介电层25将第二栅极电极26完全覆盖，介电层25可同时提高薄膜晶体管201的开启电流以及降低栅极及源漏极之间的电容效应，进而提升显示面板的显示质量；平坦层27设置在源漏电极26及介电层25上，一方面是使得所述薄膜晶体管201的表面更加平坦化；另一方面是为了减小连接薄膜晶体管201结构的数据线与源漏极26之间的电容，降低数据线的负载；阳极28设置在平坦层27上，其中阴极设于所述有机层中，在此不作具体的赘述。
像素定义层3设于所述薄膜晶体管层2的上表面，像素定义层3可以采用不同的光阻材料，在此不做限定；发光层4覆盖在像素定义层3的上表面。
在封装工艺的过程中，第一无机层51形成于发光层6的表面上以及通孔101内侧壁，第一无机层51延伸至介电层25的表面；有机层6形成于第一无机层51的上表面及通孔101内；通孔101内的有机层形成所述准直器；第二无机层52形成于有机层6的上表面；触控层7设于第二无机层52的上表面；偏光片8设于触控层7的上表面，偏光片8为透明的玻璃材质，可以提高入光量；盖板9为透明玻璃盖板，设于偏光片8的上表面，盖板9是通过光学胶贴附于偏光片8的上表面，光学胶具有高适光率、高粘接强度的特点。
通孔101位于所述第二显示区，且依次贯穿于发光层4、像素定义层3、平坦层26及第二栅极绝缘层232；其中在显示面板中，可以设置多个通孔101，有机层6是通过喷墨打印的方式将通孔101完全地填充形成所述准直器，进而当所述第一显示区用于显示时，所述第一显示区和所述第二显示区同时显像，且所述第一显示区与所述第二显示区保持相同的屏幕分辨率；当所述第一显示区用于拍摄时，第一显示区具有良好的透光性。
感光传感器103设于基板1远离所述准直器的一侧，所述感光传感器103具有一感光侧1031，该感光侧对应的朝向所述准直器，通过薄膜封装的工艺，有机层6完全填充通孔101形成对应的所述准直器。
通孔101设于两个薄膜晶体管201之间，通孔101中的有机材料为透明材质，被填充的聚合物为亚克力材料，优选为聚甲基丙烯酸甲酯，可以使更多的光线聚集在感光传感器103上；在通孔101边缘的像素定义层3以及平坦层27的材料优选为聚酰亚胺，可以减少光线的散射。其中，有机层6的折射率大于像素定义层3的折射率，同时有机层6的折射率也大于像素平坦层28的折射率，这样可以使更多的光线聚集到感光传感器103，进而可以提高所述摄像区的透光性，且维持具有较好的分辨率。
本实施例中的显示面板可以设置多个通孔101用以形成多个所述准直器。当光线照射到显示面板时，光线依次穿过盖板9、偏光片8、第二无机层52、有机层6、第一无机层51、发光层4、像素定义层3、所述薄膜晶体管层2及基板1，光线聚集在感光传感器103上。其中光线主要是先聚焦在显示面板的通孔101中，然后光线穿过透明的基板1，最后在透明的PI基板的作用下，光线聚集在感光传感器103上，从而提高所述摄像区的透光性，同时也保证了屏幕的分辨率。
在另一个实施例中，感光传感器103的基板1具有凹槽102，每一凹槽102对应一感光传感器101，凹槽102下凹于基板1的下表面，凹槽102与通孔101相对设置，且位于所述第一显示区，在封装工艺的过程中，有机材料在通孔101内形成所述准直器；另外，凹槽102的深度大于基板1厚度的一半，这样可以使光线更容易穿透基板1，聚集在感光传感器103上，进而提高所述第一显示区的透光性，同时也保证了屏幕的分辨率。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
