Description

光学组件以及显示装置 技术领域
本申请涉及显示技术领域，尤其涉及一种光学组件以及显示装置。
 背景技术
随着移动终端的迅速发展，移动终端己经成为人们生活中必不可少的一种工具，并且为用户生活的各个方面带来了极大的便捷。在用户习惯了普通的显示屏之后，为了给用户带来更好的视觉体验和视觉感受，全面屏应运而生。全面屏是指屏占比接近100%的显示屏。
如图1a所示，由于全面屏的占屏比已经接近100%，在放置前置摄像头时只能将摄像头放置在显示屏的下方，然后在摄像头上方的全面屏处进行开孔，以使摄像头能够正常工作。但是在全面屏开孔时，需要对盖板和玻璃基板进行切割等处理，工艺复杂、而且容易造成全面屏的显示异常。
如图1b所示，为了避免需要对盖板和玻璃基板进行切割等处理，现有技术提供了一种新方式，即不切割盖板和玻璃基板，仅去除摄像头上方区域内的偏光片以及光学胶，保留盖板以及显示面板，该方式在一定程度上降低了工艺复杂度，但是也存在一些问题：
如图1c所示，入射光（摄像头的入射光）在盖板以及显示面板处发生多次反射后，才能进入摄像头，这些反射将导致摄像头的进光量减小，同时还会干扰摄像头的成像质量。
即现有技术存在入射光在进入摄像头时反射率较大的技术问题。
