APPARATUS AND METHOD FOR ULTRASONIC FINGERPRINT AND TOUCH SENSING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240127620 titled 'APPARATUS AND METHOD FOR ULTRASONIC FINGERPRINT AND TOUCH SENSING
Simplified Explanation
An ultrasonic fingerprint sensor described in the patent application includes sensor pixels with interleaved ultrasonically-sensitive regions. Each sensor pixel has nine distinct ultrasonically-sensitive regions electrically coupled to a common readout circuit, with an ultrasonically-sensitive region of another sensor pixel placed between each of the nine distinct ultrasonically-sensitive regions. The sensor also features circuitry for binning together groups of sensor pixels during lower-resolution operations like touch sensor operations. This technology is used for capturing fingerprint images for authentication purposes.

Original Abstract Submitted
an ultrasonic fingerprint sensor may include sensor pixels with interleaved ultrasonically-sensitive regions. each of a plurality of sensor pixels in the ultrasonic fingerprint sensor may include nine distinct ultrasonically-sensitive regions electrically coupled to a common readout circuit, where there is an ultrasonically-sensitive region of another sensor pixel disposed between each of the nine distinct ultrasonically-sensitive regions. the ultrasonic fingerprint sensor may further include circuitry for binning together groups of sensor pixels during certain lower-resolution operations such as touch sensor operations. the ultrasonic fingerprint sensor may be used in capturing fingerprint images that are then used in an authentication process.
