Document Type and Number:
WIPO Patent Application WO/2018/223735
Kind Code:
A1
Abstract:
Provided are a fingerprint identification substrate, a fingerprint identification method, and a display device. The fingerprint identification substrate comprises a base (10), an emission portion, a reception portion, and a fingerprint detector. The emission portion and the reception portion are provided at the base (10). At least a portion of the emission portion and at least a portion of the reception portion can be arranged at the same layer. The emission portion is used to generate an ultrasonic signal. The reception portion is used to receive an ultrasonic signal reflected by a finger, to convert the ultrasonic signal to an electric signal, and to output the same to the fingerprint detector. The fingerprint detector is used to determine fingerprint information according to the electric signal outputted by the reception portion.
