Abstract
The present disclosure provides a fingerprint identification structure and a display device. The fingerprint identification structure includes an acoustic wave emitter, a focus acoustic lens, and a sound wave receiver. The acoustic lens are between the acoustic wave emitter and the sound wave receiver, the acoustic wave emitter is at a focal position of the acoustic lens and configured to emit acoustic wave toward the acoustic lens, the acoustic wave receiver is configured to detect the intensity distribution of the acoustic wave emitted by the acoustic wave emitter after the acoustic wave sequentially passes through the acoustic lens and the acoustic wave receiver, reaches the surface of the finger and is reflected back by the surface of the finger. The fingerprint recognition structure improves design flexibility.
