本申请涉及显示技术领域，具体涉及一种显示面板以及移动终端。
 背景技术
有源矩阵有机发光二极体（Active Matrix Organic Light Emitting Diode，AMOLED）的显示面板中，采用薄膜晶体管驱动，可以对各个像素单独点亮，具有亮度高，分辨率高，功耗低，易于实现色彩化和大面积显示等优点，是现在普遍采用的方法。
为了提高屏占比，当前应用的显示面板采用边缘弯曲的屏幕，屏幕的边缘也参与显示。然而，由于弯曲的屏幕边缘显示存在一定角度，边缘的亮度会比中心的亮度低，使得整个屏幕存在亮度差异，影响机主观感体验。

其中，所述源漏极金属层210通过过孔与所述有源层203的两端电连接，所述阳极金属层301与所述源漏极金属层210电连接；所述显示面板100的非显示区12的部分设置有有机绝缘层209，所述有机绝缘层209由上至下依次贯穿所述层间绝缘层208、所述第二栅极绝缘层206、所述第一栅极绝缘层204、所述第二缓冲层202以及所述第一缓冲层201并暴露出所述第二柔性层103。本申请实施例设置所述有机绝缘层209的目的主要是用于减轻所述显示面板100在弯折时产生的应力。
在本申请实施例中，所述发光功能层30包括所述阳极金属层301、设置于所述阳极金属层301上的有机发光层302以及设置于所述有机发光层302上的阴极金属层303。
如图2所示，为本申请第一实施例提供的显示面板100中显示区11的划分示意图；其中，所述显示区11包括中心显示区111以及位于所述中心显示区111外围的边缘显示区112。
如图3所示，为本申请第一实施例提供的显示面板100位于边缘显示区112的截面结构图；其中，所述边缘显示区112内还设置有与所述发光功能层30同层设置的像素定义层212，所述像素定义层212包括多个第一像素开口2121，所述发光功能层30包括多个第一像素单元，一所述第一像素单元与一所述第一像素开口2121对应；
其中，所述边缘显示区112内还设置有光学调节构件80，所述光学调节构件80包括设置于所述第一像素开口2121侧壁上的第一光学调节层81、以及覆盖所述第一光学调节层81和所述发光功能层30的第二光学调节层82，所述第一光学调节层81的折射率小于所述第二光学调节层82的折射率。
在本申请实施例中，所述第一光学调节层81包括设置于所述像素定义层212上的平坦部811以及设置于所述第一像素开口侧壁上并与所述平坦部811连接的倾斜部812；

如图4所示，为本申请第一实施例提供的显示面板100位于中心显示区111的截面结构图；其中，位于所述中心显示区111内的部分所述像素定义层212还包括多个第二像素开口2122，所述发光功能层30还包括多个第二像素单元，一所述第二像素单元与一所述第二像素开口2122对应；
其中，所述第二像素开口2122内还包括所述发光功能层30以及设置于所述发光功能层30上的所述第二光学调节层82，所述薄膜封装层40覆盖所述第二光学调节层82。

在本申请实施例中，所述第二光学调节层82的折射率n2以及所述第一光学调节层81的折射率n1之间的大小关系为：n2>n1。
具体地，当所述有机发光层302发出的光经过所述第二光学调节层82传播至所述第一光学调节层81时，由于所述第二光学调节层82的折射率大于所述第一光学调节层81的折射率，根据全反射原理，从光密到光疏，入射角为θ的出射光（θ> acrsin（n1/n2））的光不能透过所述第一光学调节层81，上述出射光在所述第二光学调节层82与所述第一光学调节层81之间的接触界面发生全反射，出射光全部反射至所述第二光学调节层82中，并出射至所述显示面板100的发光侧。由于所述边缘显示区112的部分出射光发生全反射，而所述中心显示区111的出射光并未发生变化，从而增强了所述边缘显示区112的亮度，弥补由视角产生的和中心区域的亮度差异。
针对当前技术的显示面板100因采用边缘弯曲的屏幕导致边缘屏幕的亮度比中心屏幕的亮度低的技术问题，本申请实施例提供一种显示面板100，该显示面板100包括位于中心显示区111外围的边缘显示区112，边缘显示区112内设置有衬底10、位于衬底10上的发光功能层30、及设置于发光功能层30上的光学调节构件80，光学调节构件80靠近发光功能层30一侧的折射率小于光学调节构件80远离发光功能层30一侧的折射率；本申请通过在边缘显示区112内设置光学调节构件80，且光学调节构件80靠近发光功能层30一侧的折射率小于光学调节构件80远离发光功能层30一侧的折射率，使得外界入射光在两种不同折射率材料的界面发生全反射，此部分光再经过高折射率膜层而出光，从而增强了边缘显示区112的亮度，弥补了边缘显示区112与中心显示区111之间的亮度差异，提高了显示面板100的对比度，进一步提高了显示面板100的出光效率。
实施例二
如图5所示，为本申请第二实施例提供的显示面板100位于边缘显示区112的截面结构图。其中，本申请第二实施例与本申请第一实施例相同或相似，不同之处仅在于：
所述显示面板100还包括反射层90，所述反射层90设置于所述第一像素开口2121的侧壁上，且所述反射层90位于所述像素定义层212与所述第一光学调节层81之间。所述反射层90用于反射所述光学调节构件80中的光线，可以更好的汇聚进入所述光学调节构件80中的光线，进一步减少光线的损失。
在本申请实施例中，所述反射层90经过沉积工艺形成于所述像素定义层212与所述第一光学调节层81之间，所述反射层90的材料为金属银。
在本申请实施例中，相邻两所述第二像素开口2122的间距小于相邻两所述第一像素开口2121的间距。这样设置可以增加所述边缘显示区112中所述第一像素单元的数量，从而弥补所述边缘显示区112与所述中心显示区111之间的亮度差异。
针对当前技术的显示面板100中边缘屏幕的亮度比中心屏幕的亮度低的技术问题，本申请实施例提供一种显示面板100，该显示面板100包括位于中心显示区111外围的边缘显示区112，边缘显示区112内设置有衬底10、位于衬底10上的发光功能层30、及设置于发光功能层30上的光学调节构件80，光学调节构件80靠近发光功能层30一侧的折射率小于光学调节构件80远离发光功能层30一侧的折射率；本申请通过在边缘显示区112内设置光学调节构件80，且光学调节构件80靠近发光功能层30一侧的折射率小于光学调节构件80远离发光功能层30一侧的折射率，使得外界入射光在两种不同折射率材料的界面发生全反射，此部分光再经过高折射率膜层而出光，同时，在边缘显示区112中的像素开口侧壁上设置反射层90，且反射层90位于像素定义层与第一光学调节层81之间；本申请实施例二相比本申请实施例一进一步增强了边缘显示区112的亮度，更进一步弥补了边缘显示区112与中心显示区111之间的亮度差异，提高了显示面板100的对比度，更进一步提高了显示面板100的出光效率。

在本申请的上述实施例中，所述光学调节构件80的材料可以是光刻胶、金属氧化物、有机物以及无机物中的至少一种，只要上述两者满足高透过率和折射率要求即可。
在本申请的上述实施例的一种方案中，所述第二光学调节层82的折射率沿所述显示面板100的透光方向逐渐增加，这样设置可以使所述发光功能层30发出的光线经所述第二光学调节层82折射后发散，从而增加所述显示面板100的发光亮度。
在本申请的上述实施例的另一种方案中，所述第二光学调节层82的折射率由所述第二光学调节层82的中心位置至边缘位置逐渐增加，这样设置可以增强所述发光功能层30发出的光线经所述第二光学调节层82折射后的聚光性，从而增加所述显示面板100的对比度。
在本申请的上述实施例中，所述第一柔性层101以及所述第二柔性层103的材料为聚酰亚胺，所述阻挡层102的材料为硅氮化物或硅氧化物。本申请实施例采用双层聚酰亚胺结构取代传统的玻璃基底或单层聚酰亚胺结构，能够实现显示面板100的折叠和柔性显示，同时实现更好的弯折及水氧阻隔性能。
在本申请的上述实施例中，所述显示面板100采用双栅极结构，双栅极结构相比单栅极结构具有更优的性能，如电子迁移率更高，开态电流较大、亚阈值摆幅更小、阈值电压的稳定性及均匀性更好、栅极偏压及照光稳定性更好等。
在本申请的上述实施例中，所述薄膜封装层40包括由下至上设置的第一无机封装层、有机封装层以及第二无机封装层。
优选地，所述第一无机封装层以及所述第二无机封装层通过等离子体增强化学的气相沉积法(Plasma Enhanced Chemical Vapor Deposition，PECVD)、原子层沉积技术(Atomic layer deposition technique，ALD)、脉冲激光沉积技术(PulsedLaser Deposition，PLD)以及溅镀技术(Sputter)等工艺制备。
