Abstract: PURPOSE: A fingerprint contact sensor is provided to sense a variation of alternating current frequency, occurring at a fingerprint contact, by using a contact LED(Light Emitting Device), and maintain an idle state when there is no fingerprint contact so that it can enhance a product reliability. CONSTITUTION: A fingerprint contact sensor comprises an inverter(11), a fingerprint input module(12), an amplitude variation sensor(13) and a comparator(14). The inverter(11) outputs selectively a first alternating current or a second alternating current according to an idle state of the fingerprint input module(12). The fingerprint input module(12) maintains the idle state when the first alternating current is supplied from the inverter(11), and generates a photo image when the second alternating is supplied from the inverter(11). The amplitude variation sensor(13) senses the amplitude variation from the second to the first alternating current. The comparator compares the amplitude variation signal with a reference, and if the compared result is more than a set value, it generates a high level signal for making the inverter(11) generate the second alternating current. The fingerprint input module(12) includes a contact LED(12a), a lens(12b) and an image sensor(12c). The fingerprint gets contacted on a surface of the contact LED(12a), then the LED generates a photo image having the fingerprint pattern, the photo image is projected on a surface of the image sensor(12c), and the image sensor(12c) converts the photo signal into the electric image signal.
