Description

显示面板及显示装置 技术领域
本发明涉及显示领域，尤其是涉及一种显示面板及显示装置。
 背景技术
在中小尺寸显示领域，全面屏技术成为当前的重点研发方向，也即如何通过相关技术的开发实现人机交互界面的屏占比最大化。第一代全面屏技术主要集中于屏幕尺寸比例由16:9变化为18：9甚至更大；第二代全面屏就则是进一步地压缩屏幕上下左右的边界，甚至采用柔性折叠技术最大化可视面积。而近期全面屏的另一个研究方向则是如何将显示终端的指纹识别、摄像头、面部识别、距离传感等传感器进一步地融合进显示屏的显示区，使得显示屏从单纯的显示界面逐渐过渡到全面的感知、交互界面。
目前主流的显示技术包括液晶显示器（LCD）和有机发光二极管（OLED），其中LCD为被动发光技术，通过整面背光结构照射液晶盒实现光纤的亮暗控制，而OLED技术则是采用逐颗的OLED像素主动发光，相较而言OLED具有高对比、轻薄、可弯曲、可折叠等优势。另一方面，基于OLED无法背光的特性，可以很好的与现行的光学指纹识别模组兼容，因而面内光学指纹识别成为目前OLED的“独有优势”，同时业界也在开发基于OLED的屏下摄像头方案，从而可以进一步在显示模式和摄像模式间切换并且无需现行LCD挖孔方案所造成的挖孔区无法显示等优势。
 技术问题
但是通常屏下成像需要更高的像素密度，因而传感器单个感光单元较小且对于OLED基板穿透率具有较高的要求，这一点与指纹识别仅需要通过OLED子像素间透光就能满足成像需求有所不同。目前现行的OLED就是通过有源驱动（AM）方式驱动的，其中AM主动阵列驱动的优势在于能够兼容更高分辨率的驱动，但是劣势在于需要较多的薄膜晶体管（TFT）进行电性的连接，最基本的驱动架构为2T1C，而现行消费级的产品应用更是采用7T1C的架构，其中多个TFT架构构成了极大的开口占用，使得OLED显示难以实现高透光率设计，因而难以与屏下摄像方案做很好的兼容。
因此，有必要提出一种新的显示面板及显示装置，解决了现有技术中OLED摄像区的透光率低的问题，减小多个TFT架构构成了开口占用，实现真正的全面屏技术。
