Methods and Apparatus of Integrating Fingerprint Imagers with Touch Panels and Displays

摘要

The present invention provides systems and methods of an apparatus that comprises a layer of fingerprint imagers, an addressing circuit, a fingerprint controller, an electronic storage devices, a layer of touch panel and a display panel. The touch panel behind the layer of fingerprint imagers can sense touch position when touched. The specific fingerprint imagers can be activated according to the touch panel coordinates when touched by a user. After fingerprint is captured, the system evaluates quality of the captured fingerprint and admits fingerprint for recognition when its quality is above a threshold value. User of a computing system can be accepted or rejected based on the comparison between the captured fingerprint and an authorized fingerprint list.

主权项

1. A touch-fingerprint apparatus comprises,
at least one layer of one or a plurality of fingerprint imagers; at least one addressing circuit coupled with said fingerprint imagers wherein said addressing circuit can drive the fingerprint imagers using line and column addresses; at least one set of electronic storage devices coupled with said fingerprint imagers wherein said electronic storage devices receive and store sensed fingerprint outputs from the fingerprint imagers; at least one fingerprint controller coupled with the addressing circuit and the electronic storage devices; and at least one touch panel behind the layer of fingerprint imagers.
