Title:
UNDER-SCREEN OPTICAL DETECTION SYSTEM, ELECTRONIC DEVICE AND OBJECT APPROACH DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/056939
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of optical detection. Disclosed are an under-screen optical detection system, an electronic device and an object approach detection method. The under-screen optical detection system is arranged under a display screen so as to perform under-screen optical detection, and is characterized by comprising an optical sensor and a light source, wherein the light source is used for emitting excitation light to a target object above the display screen, the excitation light returns from a surface of the target object and then forms returned light, and the returned light penetrates through the display screen and is received by the optical sensor under the display screen so as to perform the under-screen optical detection; and the optical sensor is used for receiving the returned light from the target object above the display screen and performing the under-screen optical detection, and the under-screen optical detection comprises biological characteristic information detection, and object approach detection performed by means of multiplexing the optical sensor.
