FINGERPRINT RECOGNITION SENSOR CAPABLE OF SENSING FINGERPRINT USING OPTICAL AND CAPACITIVE METHOD |
| 摘要 |
Provided is a fingerprint recognition sensor capable of sensing a fingerprint using optical and capacitive methods, the sensor including: a capacitive fingerprint sensing unit that includes a transistor (T2) in which a flowing current is changed depending on an output voltage of a fingerprint sensing electrode capable of sensing the humans fingerprint; and an optical fingerprint sensing unit which changes the flowing current in the transistor (T2) due to a difference in reverse current of a photodiode generated by light and shade depending on existence or non-existence of the fingerprint. |
