In a self-capacitive sensing mode, the scanning driver drives a pair of adjacent scanning lines among the scanning lines and the sensing driver performs self-capacitive sensing through at least one sensing line among the sensing lines to obtain a first fingerprint sensing signal. In a mutual-capacitive sensing mode, the scanning driver drives the pair of adjacent scanning lines and the sensing driver performs mutual-capacitive sensing through at least two adjacent sensing lines among the sensing lines to obtain a second fingerprint sensing signal. The processing module generates a first fingerprint pattern and a second fingerprint pattern according to the first fingerprint sensing signal and the second fingerprint sensing signal and combines the first fingerprint pattern and the second fingerprint pattern into a combined fingerprint pattern."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Capacitive fingerprint sensing apparatus and capacitive fingerprint sensing method","description":"A capacitive fingerprint sensing apparatus including sensing electrodes, a scanning driver, a sensing driver and a processing module is disclosed.
