Document Type and Number:
WIPO Patent Application WO/2020/052327
Kind Code:
A1
Abstract:
The present invention relates to the technical field of optical fingerprints, and provided thereby are a method for automatically searching for thickness parameters of a display screen, a storage medium and an electronic device. The method for automatically searching for thickness parameters of a display screen comprises the steps of: processing a fingerprint image to determine a circular dark area corresponding to any point light source, the diameter of the circular dark area being D; and calculating screen thickness parameters according to the value of D. In the present invention, information of lensless imaging is effectively utilized to calculate screen thickness parameters in real time, which is beneficial for subsequent data processing.
