Integrated fingerprint sensor and display

摘要

A fingerprint swipe sensor includes fingerprint sensor lines disposed on a surface of an LCD protective glass covered on an opposite surface with motion sensing lines. The fingerprint swipe sensor also includes a controller coupled to the fingerprint sensor lines to capture a fingerprint image when a user's finger is swiped about the fingerprint sensor lines.

主权项

1. A touch screen display device having integrated touch sensing and biometric image capture capabilities, comprising:
a top layer, comprising a display protective glass layer; a lower layer; touch sensitive circuitry disposed intermediate the top layer and the lower layer, the touch sensitive circuitry being configured to detect touch input; and a biometric object image sensor disposed intermediate the top layer and the lower layer, the biometric object image sensor comprising electrode traces forming an array of capacitive gap sensing elements, wherein the array includes at least one image pixel location defined by a capacitive coupling gap between a respective signal drive trace and a respective signal pickup trace to capture a biometric object image when a biometric object of a user is above the biometric object image sensor and the display protective glass layer.
