Embodiment Construction

[0041] Fingerprint sensing is a useful authentication tool for use in mobile and other applications that use, provide or require secure access. For example, fingerprint sensing can be used to provide secure access to mobile devices, electronic devices or systems, or to provide electronic portals to one or more systems or databases, and can be used to secure financial transactions including online purchases and other digital information. There is a need to include robust and reliable fingerprint sensor features suitable for mobile or wearable devices, while providing such fingerprint sensors with a thin structure with a small footprint to fit in very mobile or portable devices and other compact devices. limited space. In some applications, it is also desirable to include a protective cover to protect this fingerprint sensor from various contaminants and to provide a user interface for touch sensing and certain user operations.

Abstract

In one aspect, a fingerprint sensor device includes a touch panel with an integrated touch sensor module. The integrated touch sensor module includes sensing circuitry for generating sensor signals responsive to detected touch inputs associated with fingerprints. The sensing circuitry includes a fingerprint sensor for detecting the contact input and generating a signal indicative of an image of the fingerprint, and a biometric sensor for generating a signal indicative of a biometric identification other than the fingerprint. The generated sensor signal includes a signal indicative of the image of the fingerprint and a signal indicative of a biometric identification other than the fingerprint. The sensing circuit includes processing circuitry communicatively coupled to the sensing circuit for processing the generated sensor signal to determine whether the contact input associated with the fingerprint belongs to a live finger. On the other hand, the device includes a touch screen and an optical sensor module located under the touch screen to provide optical fingerprint sensing.

Description

[0001] cross reference [0002] This patent document claims priority to U.S. Provisional Patent Application No. 62 / 181,718, filed June 18, 2015, entitled MULTIFUNCTION FINGERPRINT SENSOR AND PACKAGING, which The entire contents of this patent document are incorporated by reference. technical field [0003] This patent document generally relates to fingerprinting for secure access to electronic devices, including mobile and wearable devices. Background technique [0004] Electronic devices, including portable or mobile computing devices (eg, laptops, tablets, smartphones, and gaming systems), may employ user authentication mechanisms to protect personal data and prevent unauthorized access. User authentication on electronic devices may be performed by one or more forms of biometric identifiers, which may be used alone or in addition to conventional password authentication methods. A popular form of biometric identifier is a person's fingerprint pattern. A fingerprint senso...
