Fingerprint sensor and integratable electronic display

摘要

A fingerprint sensor which includes a conductive layer which is incorporatable within an electronic display is disclosed. The fingerprint sensor also includes a controller coupled to the conductive layer to capture a fingerprint image and can further be adapted to control the display.

主权项

1. A system, comprising:
a cover glass; a fingerprint sensor formed of direct build-up patterned conductors disposed on the cover glass, wherein the direct build-up patterned conductors are passive traces forming an image sensing array of capacitively coupled drive elements and pick up elements; a flexible connector connected to the patterned conductors; a chip mounted on the flexible connector, the chip being configured to control the fingerprint sensor, wherein the chip comprises an excitation circuit for energizing the drive elements and a detection circuit for detecting corresponding signals received from the pickup elements; and a display module below the cover glass, the display module being configured to produce a visible display.
