  • Fingerprint sensing method based on touch pressure in black screen mode of touch input device and touch input device for the same
    Patent number: 10949644
    Abstract: A fingerprint sensing method based on touch pressure in a black screen mode of a touch input device according to the embodiment of the present invention includes: sensing first pressure which has a value equal to or greater than a first predetermined threshold value and is applied by an object in the black screen mode; determining continuously after sensing the first pressure whether second pressure which has a value equal to or greater than a second predetermined threshold value and is different from the first pressure is sensed or not; recognizing a fingerprint of the object when the second pressure is sensed; determining whether or not the recognized fingerprint is identical to a fingerprint previously registered in the touch input device; and performing a predetermined operation when the recognized fingerprint is identical to the previously registered fingerprint.
