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显示装置。
 背景技术
指纹识别在便携电子产品中使用广泛，不仅用于屏幕解锁，还可用于手机支付等，增加了使用安全性。传统指纹识别的区域在屏幕以外，随着高屏占比的发展趋势，对于100%全面屏来讲，手机正面已经没有区域可以放置指纹传感器，因此屏下指纹识别是手机指纹识别的发展趋势。
对于有机发光二极管（Organic Light-Emitting Diode, OLED）显示装置，由于其自发光特性以及发光层的透过率较高，满足指纹识别的条件，易于实现屏下指纹识别，但对于液晶显示装置（ Liquid Crystal Display, LCD）来讲，由于其需要背光源，一方面背光源相较于OLED的主动发光式其亮度较低，且需穿过上下偏光片和液晶面板，其透过率很低，难以满足光学式指纹识别的要求。同时，虽然也有超声波识别的方式，但由于目前LCD盖板厚度在0.6-0.9mm左右，超过了超声波穿透的最大厚度0.4mm，因此其识别效果仍然不佳。
综上所述，现有液晶显示面板及显示装置存在屏幕下指纹识别效果不佳的问题。故，有必要提供一种显示面板及显示装置来改善这一缺陷。
