Title:
FLEXIBLE DISPLAY SCREEN PANEL FOR FINGERPRINT IDENTIFICATION
Document Type and Number:
WIPO Patent Application WO/2020/118976
Kind Code:
A1
Abstract:
Disclosed in the present invention are a flexible display screen panel for fingerprint identification, and a manufacturing method therefor. The flexible display screen panel for fingerprint identification comprises a PI substrate, a buffer layer, a functional layer, a touch layer and an optical fingerprint identification module which are provided in sequence. The PI substrate is provided with a first light-transmitting region; the buffer layer is provided on the PI substrate; the functional layer is provided on the buffer layer; the touch layer is provided on the functional layer; and the optical fingerprint identification module is provided below the first light-transmitting region. By providing light-transmitting regions on the PI substrate and designing the light-transmitting regions into a concave lens configuration, the present invention improves the identification accuracy and identification efficiency of a fingerprint identification module for a fingerprint to be identified, reduces time taken for unlocking, and improves customer experience. In addition, two light-transmitting regions are provided on the PI substrate, so that unlocking using fingerprints of two fingers at the same time can be realized.
