DEVICES CONFIGURED FOR NEAR-FIELD ULTRASONIC IMAGING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240338964 titled 'DEVICES CONFIGURED FOR NEAR-FIELD ULTRASONIC IMAGING
The abstract describes a patent application for a display system with an ultrasonic fingerprint sensor system, including a stiffener layer between the two stacks.
- The stiffener layer allows the ultrasonic fingerprint sensor system to operate in a near-field mode.
- The near-field mode involves transmitting ultrasound with a peak frequency ranging from 1 megahertz (MHz) to 6 MHz.
Potential Applications: - This technology can be used in smartphones, tablets, and other electronic devices that require fingerprint authentication. - It can also be applied in security systems, access control devices, and biometric identification systems.
Problems Solved: - The technology solves the problem of integrating a fingerprint sensor system with a display stack without compromising functionality. - It addresses the need for secure and convenient biometric authentication in various devices.
Benefits: - Improved security with ultrasonic fingerprint sensing technology. - Enhanced user experience with seamless integration of fingerprint authentication. - Increased convenience and efficiency in accessing devices and applications.
Commercial Applications: Title: "Enhanced Security and User Experience in Electronic Devices with Ultrasonic Fingerprint Sensor System" This technology can be commercially used in smartphones, tablets, laptops, access control systems, and other electronic devices requiring secure biometric authentication.
Questions about Ultrasonic Fingerprint Sensor System: 1. How does the stiffener layer enable the ultrasonic fingerprint sensor system to operate in a near-field mode? The stiffener layer provides the necessary support and thickness for the sensor to function effectively in close proximity to the display stack.
2. What are the advantages of operating the ultrasonic fingerprint sensor system in a near-field mode? Operating in the near-field mode allows for more accurate and reliable fingerprint authentication, enhancing security and user experience.
Original Abstract Submitted
some disclosed devices include a display system having a display stack, an ultrasonic fingerprint sensor system including an ultrasonic fingerprint sensor system stack and a stiffener layer residing between the display stack and the ultrasonic fingerprint sensor system stack. in some examples, the stiffener layer may have a stiffener layer thickness that allows the ultrasonic fingerprint sensor system to operate in a near-field mode. according to some examples, operating in the near-field mode may involve transmitting ultrasound having a peak frequency in a range from 1 megahertz (mhz) to 6 mhz.
