The optical fingerprint sensor includes a plurality of pixels, and each of the pixels has a first control signal line and a second control signal line. Each of the pixels is further coupled to a first voltage source line, a second voltage source line and a sensing line. The control method includes a plurality of steps, and the steps are applying a first anti-loading driving (ALD) signal on the second control signal line, and applying a second ALD signal on at least one of the first control signal line, the first voltage source line, the second voltage source line and the sensing line."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control method for optical fingerprint sensor and related control circuit and optical fingerprint sensor","description":"A control method for an optical fingerprint sensor is provided for canceling or reducing capacitive loading.
