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.
