Portable Device with Security Module

摘要

The present invention provides an electronic device providing with a security mode and an operation mode, wherein the electronic device includes a touch panel having a sensing array. A sample fingerprint is fetched by using the sensing array; a detected fingerprint is fetched by sensing a fingerprint using the sensing array in the security mode. The sample fingerprint is compared with the detected fingerprint in the security mode, followed by unlocking the electronic device if the detected fingerprint matches with the sample fingerprint, and switch the electronic device into the operation mode. A control signal is generated in responsive to a touching event, followed by controlling a virtual object displayed on a display in responsive to the control signal.

主权项

1. A mobile phone, comprising:
a control unit; a display coupled to said control unit; a sensing array formed over said display, wherein said mobile phone includes a security mode and an operation mode coupled to said control unit, wherein said sensing array includes a first electrode array and a second electrode array to sense a first direction axis and a second touching events to determines touching position, wherein at least one of said first electrode array and said second electrode array includes carbon nanotubes or graphene; and a security module for fetching capacitance of a user finger, thereby generating a capacitance pattern; wherein each pixel of said sensing array acts as one plate of a parallel-plate capacitor, dermal layer of said user's finger acts as the other plate of said parallel-plate capacitor, and non-conductive epidermal layer of said user's finger acts as a dielectric layer of said parallel-plate capacitor.
