随着智能手机的更新换代，高屏占比手机的市场占率越来越高。为了提高手机的屏占比，手机厂商会尽量把传感器设计到屏幕下。目前，屏下指纹识别技术已经实现商用，屏幕发声，屏下虹膜识别技术也越来越成熟，这促进了手机的屏占比进一步提高。但前置摄像头对成像质量要求较高，而屏下摄像头成像质量不佳，使得屏下摄像头的实现难度较大。为了实现屏下摄像头，有许多设计方法。
一般来说是降低前置摄像头区域上方屏幕的像素密度，屏下摄像头区域有部分区域无金属走线，可以透过光线，用于前置摄像头拍照使用。由于屏下摄像头区域像素密度较低，发光面积小，这会导致屏下摄像头区域亮度较低。但若提高屏下摄像头区域的亮度，将导致屏下摄像头区域OLED的寿命变短，长时间使用会导致屏下摄像头区域亮度异常，出现不良。
因此，有必要提出一种新的显示面板及显示装置，提高屏下摄像头区域的亮度，解决了现有技术中显示面板寿命变短、摄像头区域亮度异常的问题。

另外，由于所述透光显示区120的第二发光单元1121的密度低，整个子像素数量少，因而，对Micro LED转移良率要求不会太苛刻。
如图4所示，本发明还提供一种显示装置200，包括所述显示面板100以及摄像模块201，所述摄像模块201设于所述显示面板100下方且对应所述透光显示区120。
本发明显示面板及显示装置通过在显示面板的透光显示区设置Micro LED作为透光显示区的显示单元，可以提高透光显示区的亮度，可以解决现有技术中显示面板寿命变短、摄像头区域亮度异常的问题。并且本发明由于Micro LED为无机材料，其发光效率高，且寿命长，因而即使所述透光显示区的第二发光单元亮度比所述主显示区的第一发光单元的亮度更高，也不会发生明显衰减。另外，由于所述透光显示区的第二发光单元的密度低，整个子像素数量少，因而，对Micro LED转移良率要求不会太苛刻。
本发明的技术范围不仅仅局限于所述说明中的内容，本领域技术人员可以在不脱离本发明技术思想的前提下，对所述实施例进行多种变形和修改，而这些变形和修改均应当属于本发明的范围内。
