Abstract
一种屏下指纹识别模组、显示组件及显示装置，该屏下指纹识别模组包括：衬底基板(101)、设置于衬底基板(101)上的多个指纹识别单元，每个指纹识别单元包括感光单元(S)、设置于感光单元(S)的感光面一侧的光学结构，光学结构包括透光环(H)和透光孔(K)，透光环(H)和透光孔(K)在远离感光单元(S)方向上依次设置，透光环(H)在感光单元(S)上的正投影完全位于感光单元(S)的感光面上，透光孔(K)在透光环(H)上的正投影位于透光环(H)包围的不透光区域内。通过光学结构引导用于指纹识别的角度较大的信号光通过透光孔(K)和透光环(H)进入感光单元(S)，使得角度较小的环境光通过透光孔(K)之后，被透光环(H)包围的不透光区域遮挡，从而避免环境光对感光单元(S)的干扰，提高指纹识别的准确率。
