 本发明的实施方式
下面详细描述本发明的实施方式，所述实施方式的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施方式是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。
请参阅图1，图1为本发明实施例提供的OLED显示面板的截面示意图。
本发明实施例提供一种OLED显示面板，包括：
发光基板10，发光基板包括第一发光区11和弯折区12；
封装薄膜20，封装薄膜20设置在发光基板10上；其中，
封装薄膜20内设置有第一光学器件30，且第一光学器件30在发光基板10上的投影位于第一发光区11与弯折区12交接处，以使第一发光区11的光线通过第一光学器件30射入弯折区12。
具体的，该发光基板10可以是包括金属线101（Source-Drain走线）、平坦层102、阳极103、有机发光层104、阴极105以及像素定义层106。以及形成在该发光基板10上的封装薄膜20，该封装薄膜20可以通过CVD（Chemical Vapor Deposition，化学气相沉积）工艺制备。其中，在该封装薄膜20内设置有第一光学器件30，当OLED显示面板工作时，由于第一光学器件30在发光基板10上的投影位于第一发光区11与弯折区12交接处，第一发光区11的一部分光线可以通过该第一光学器件30射入弯折区12内，使得弯折区12发光，进而提升弯折区12的显示效果。
可选的，请继续参阅图1，在一些实施例中，第一光学器件30包括增强部31和反射部32。其中，反射部31贴合设置在增强部32上，且反射部31在发光基板10上的投影位于第一发光区11上。
具体的，该第一光学器件30包括增强部31和反射部32。当OLED显示面板工作时，第一发光区11的光线经过反射部31形成反射光线。反射光线通过增强部32后射入弯折区12内，使得弯折区12发光，进而提升了弯折区12的显示效果。
需要说明的是，该增强部32的材料为高透光材料。由于第一光学器件30是设置在封装薄膜20内部的。因此，当光线经过第一光学器件30反射至弯折区12时，由于封装薄膜内部透光率不一致。因此反射光线的强度相对于第一发光区11的光线的强度而言，必然被削弱了很多。所以，将反射部31贴合设置在增强部32上，可以减小封装薄膜20对反射光线的削弱。
优选的，反射部31的材料为银或者氧化铟锡。
进一步的，请继续参阅图1，在一些实施例中，增强部包括相对设置的第一边和第二边，以及设置在第一边和第二边之间的第三边和第四边。
其中，反射部32贴合设置在第三边上，且第三边在发光基板上的投影位于第一发光区上。
可选的，第三边与第二边之间的夹角介于0度至90度之间。需要说明的是，可以通过调节第三边和第二边的夹角来调节发射部31和第二边的夹角，进而调节反射部31反射到弯折区12的光线的强度，具体根据实际情况进行设置。
紧接着，请参阅图2以及图3，图2为本发明一优选实施例提供的OLED显示面板的铺平状态下的截面示意图，图3为本发明一优选实施例提供的OLED显示面板的弯折状态下的截面示意图。
在一些实施例中，发光基板10还包括第二发光区13，封装薄膜内20还设置有第二光学器件40；其中，
第一光学器件30与第二光学器件40间隔设置，且第二光学器件40在发光基板10上的投影位于第二发光区13与弯折区12交接处，以使第二发光区13的光线通过第二光学器件40射入弯折区12。
具体的，该第一光学器件30与第二光学器件40间隔设置在封装薄膜20内。当OLED显示面板工作时，第一发光区11的一部分光线可以通过该第一光学器件30射入弯折区12内，以及第二发光区13的一部分光线可以通过该第二光学器件40射入弯折区12内，使得弯折区12能够同时接收到一部分第一发光区11的光线和一部分第二发光区13的光线。进一步的提升了弯折区12的显示效果。其中，第二光学器件40的结构与第一光学器件30的结构类似，具体请参阅前面实施例，在此不再赘述。
优选的，第一光学器件30与第二光学器件40的形状、大小均一致。
可选的，在一些实施例中，请参阅图4以及图5，图4为本发明另一优选实施例提供的OLED显示面板的铺平状态下的截面示意图，图5为本发明另一优选实施例提供的OLED显示面板的弯折状态下的截面示意图
封装薄膜20内还可以设置有一透镜50。
其中，透镜50在发光基板10上的投影位于弯折区12，且透镜50设置在第一光学器件30和第二光学器件40之间。
优选的，该透镜50为凸透镜，将透镜50设置在第一光学器件30和第二光学器件40之间。当OLED显示面板工作时，能够使得显示视角广度能够达到的范围更大，提高了弯折区12的显示效果，从而进一步的提高了OLED显示面板的显示效果。
进一步的，请继续参阅图4，在另一些实施例中，封装薄膜20可以包括层叠设置的第一无机层201、有机层202以及第二无机层203；其中，
第一光学器件和第二光学器件间隔设置在有机层内，透镜设置在第二无机层内，且第一光学器件和第二光学器件在发光基板上的投影，均不与透镜在发光基板上的投影重合。
相应的，本发明还提供了一种显示装置，包括本发明任一实施例的OLED显示面板。
在本实施例中，通过在封装薄膜20内间隔设置第一光学器件30以及第二光学器件40。当OLED显示面板工作时，第一发光区11的光线可以通过第一光学器件30射入弯折区12。并且，第二发光区13的光线可以通过第二光学器件40射入弯折区12可以解决弯折位置出现显示盲区的问题。因此提升了显示效果。
以上对本发明实施例提供的OLED显示面板以及显示装置进行了详细介绍，本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明。同时，对于本领域的技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本发明的限制。
