==APPARATUS AND METHOD FOR ULTRASONIC FINGERPRINT AND TOUCH SENSING - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18500762 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 regions. The sensor also features circuitry for binning together groups of sensor pixels during lower-resolution operations like touch sensor operations. The sensor is used for capturing fingerprint images for authentication purposes.

* Sensor pixels with interleaved ultrasonically-sensitive regions

==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.
