Title:
BIOMETRIC DETECTION MODULE, BACKLIGHT MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/181443
Kind Code:
A1
Abstract:
A backlight module (10), a biometric detection module (2) and an electronic device. The biometric detection module (2) may, by means of the backlight module (10), receive a detection light beam emitted and/or reflected by an external object. The detection light beam is emitted by the biometric detection module (2) or other light sources onto the external object, or the detection light beam is emitted by the external object. The detection light beam is used for the detection and identification of biometric information of the external object. The backlight module (10) may provide a backlight beam to a display panel (11). The backlight module (10) comprises a reflective sheet (110) that may transmit the detection light beam and reflect the backlight beam. The backlight module (10), the biometric detection module (2) and the electronic device have better under-screen biometric detection effects.
