Description

显示面板及显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种显示面板及其显示装置。
 背景技术
随着移动便携设备的普及化程度越来越高，高屏占比屏幕由于能给予用户更好视觉体验而成为手机、平板等电子设备的未来发展趋势。移动电子终端特别是手机追求便携性和大屏显示的双重优点，这就要求电子产品具有尽量高的屏占比。但是在手机显示屏周边，往往需要为多种光学电子元器件（听筒，前置摄像头，红外传感器等）预留位置，从而限制了屏幕边框的缩小，不易实现较高的屏占比。
为了尽量减小显示屏周边非显示区面积，现在一系列屏下内置元器件技术正在被开发。如屏下指纹识别，屏下传感等等。但是屏下摄像头技术的开发却面临了许多问题，因为摄像元器件置于显示屏下方，外界光需穿透显示屏才能被摄像元器件所接受。因此，显示屏对外界光的透过率成为影响摄像元器件成像品质的关键因素。其中，影响显示屏透过率有一个重要因素为发光元件（像素结构）对外界光的阻挡。
如图1所示，为现有一种像素结构及其对外界光的反射示意图。在现有的像素结构200中，包括阳极231、像素定义层232、发光功能层233和阴极234。其中阳极231包括第一透明导电层2311、金属反射层2312和第二透明导电层2313。屏幕显示时，金属反射层2312可以有效反射发光功能层233的光线，从而可提高屏幕的亮度。而第二透明导电层2313作为阳极231的修饰层，可以提高有机像素的发光效率。但另一方面，当屏下摄像头工作时，大量的外界光会被阳极231反射，不利于成像，外界光被阳极231反射的路径见图中所示箭头方向。
因此，如何在保证屏幕显示较高的出光效率的同时，获得较高的外界光源的穿透率，成为屏下摄像头技术的矛盾点。
基于此，有必要提供一种新的显示面板及显示装置，以克服现有技术中存在的问题。

进一步的，其中所述第一透明导电层与所述发光元件相应设置。

本发明还提供一种显示装置，包括以上所述的显示面板。
 有益效果
本发明的有益效果在于，提供一种显示面板及显示装置，通过减少金属反射层所占的面积，仅在与发光单元相对区域的中心位置相应设置金属反射层，可在实现屏幕显示较高的出光效率的同时，获得较高的外界光源的穿透率，有利于屏下摄像头成像。
