FINGERPRINT IDENTIFICATION STRUCTURE AND DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17050193 titled 'FINGERPRINT IDENTIFICATION STRUCTURE AND DISPLAY DEVICE

Simplified Explanation

The present disclosure describes a fingerprint identification structure and a display device. The structure includes an acoustic wave emitter, a focus acoustic lens, and a sound wave receiver. The emitter emits acoustic waves towards the lens, which then pass through the lens and the receiver. The receiver detects the intensity distribution of the acoustic waves after they pass through the lens, reach the surface of the finger, and are reflected back by the finger's surface. This structure improves design flexibility for fingerprint recognition.

• The structure includes an acoustic wave emitter, a focus acoustic lens, and a sound wave receiver.
• The emitter is positioned at the focal position of the lens and emits acoustic waves towards the lens.
• The lens focuses the acoustic waves and directs them towards the receiver.
• The receiver detects the intensity distribution of the acoustic waves after they pass through the lens, reach the finger's surface, and are reflected back.
• This structure allows for improved design flexibility in fingerprint recognition.

Potential Applications

This technology has potential applications in various fields, including:

• Biometric security systems
• Mobile devices (smartphones, tablets) with fingerprint recognition
• Access control systems (e.g., for buildings, vehicles)
