Description

柔性显示面板及显示装置 技术领域
本发明涉及显示领域，特别是一种柔性显示面板及显示装置。
 背景技术
手机、平板电脑等智能终端由于其集便利性、娱乐性、功能多样性于一体的特点，越来越成为人们日常生活中不可获缺的一部分，但是，随着终端技术的不断发展，更多更先进的技术在智能终端上的应用，大大地丰富了人们的生活；但是，与此同时，人们对智能终端的要求和期望也越来越高，人们在享受手机、平板电脑等智能终端带来的基础性功能的同时，也对智能终端提出了更高的要求，如智能终端的柔性显示屏设计。
随着现代显示技术的快速发展，显示技术领域正朝着更轻、更薄、更柔、更透明的方向发展。传统的玻璃基板由于自身硬和脆等特性，难以满足未来柔性显示技术的要求，而高分子薄膜基板具有质轻、柔性、综合性能优异等特点，可以很好地满足显示技术对柔性的要求。因此，柔性高分子基板材料是未来柔性显示技术的首选材料。
目前用作柔性薄膜基板最具发展前景的高分子材料是聚酰亚胺（Polyimide，PI）。聚酰亚胺具有优异的耐热性、耐辐射性能、耐化学性、电绝缘性、机械性能等，但其可见光波段的平均光学透过率仅为70%。并且，随着各显示面板膜层的叠加，整体透过率将进一步降低。
而屏下摄像技术对显示面板摄像头区域的整体光学透过率要求极高，但现有技术通常只对摄像头部位的显示器件进行线路排布设计，几乎不涉及柔性薄膜基板结构，因此显示面板下的摄像头依旧无法获取足够的光线，促使采集到的图像亮度较低，图片质量较差。
 技术问题
本发明的目的是提供一种柔性显示面板及显示装置，以解决现有技术中显示面板摄像头区域的整体光学透过率过低，因此显示面板下的摄像头无法获取足够的光线，促使采集到的图像亮度较低，图片质量较低。

在所述透明显示区，所述柔性显示面板还包括至少一组折射层结构。
进一步地，所述折射层结构包括第一折射层、第二折射层以及第三折射层。所述第一折射层具有入光侧和出光侧。所述第二折射层具有入光侧和出光侧，所述第二折射层的入光侧设于所述第一折射层的出光侧。所述第三折射层具有入光侧和出光侧，所述第三折射层的入光侧设于所述第二折射层的出光侧。所述第一折射层的折射率小于所述第二折射层的折射率。所述第二折射层的折射率小于所述第三折射层的折射率。

进一步地，当所述柔性显示面板内具有两个及两个以上所述折射层结构时，下一层级的所述折射层结构的顶面直径等于或小于上一层级所述折射层结构的底面直径。
