Abstract
(EN)
A device for fingerprint recognition and an electronic device. The device for fingerprint recognition is applicable in the electronic device provided with a flexible display screen and is capable implementing in-display fingerprint recognition of the flexible display screen. The device comprises: a support structure, used for being at least partly provided in a transparent area under the flexible display screen, the support structure being used for supporting the flexible display screen; and an optical fingerprint module, used for being provided on the support structure, the optical fingerprint module being used for collecting an optical signal reflected or scattered by a finger on the flexible display screen and transmitted from the transparent area.
