Abstract: Devices, systems, and techniques are provided for integrating a touch screen with a fingerprint detection module as an assembly for a mobile device. The integrated touch screen/fingerprint sensor assembly includes at least two glass layers bonded together to provide overall mechanical strength for the touch screen display. The upper glass layer is a toughened/hardened cover glass that does not have an opening for fitting the fingerprint detection module through this glass layer. The lower glass layer is a support glass layer underneath the hardened cover glass to provide additional mechanical strength and to include an opening at a location close to an end of the support glass layer. The integrated touch screen/fingerprint sensor assembly also includes a fingerprint detection module positioned within the opening of the support glass layer and directly underneath the hardened cover glass.

Abstract: Various embodiments can measure a distance of an object. For achieving this, a first light source and a second light source can be configured to emit first light and a second light toward the object to illuminate the object. The emission of the first light and second light can be configured such that the two lights converge at a first point and diverge at a second point. An optical sensor can be used to capture a first image of the object illuminated by the first light, and capture a second image of the object illuminated by the second light. An image difference between the first image and the second image of the object can be determined. The distance of the object with respect to the first point can then be determined based on the image difference and a distance difference between the first point and the second point.

Abstract: The disclosed optical sensing technology can be implemented to provide optical fingerprint sensing while a user finger is located near a device while not in contact with the device for user authentication in accessing the device and can further provide optical fingerprint sensing while a user finger is in contact with the device. In some implementations, the optical fingerprint sensing can be performed on a finger in contact and on-contact instances to enhance the fingerprint sensing and to provide anti-spoofing in the optical sensing. For example, multiple fingerprint images can be captured when a finger is located near a device while not in contact with the device and when the finger is in contact with the device. The captured fingerprint images of the non-contact finger and the captured fingerprint images of the contact finger provide two different types of optical fingerprint sensing mechanisms and can collectively enhance the fingerprint sensing performance and anti-spoofing feature.
