  • Patent number: 11295108
    Abstract: A control method for an optical fingerprint sensor is provided for canceling or reducing capacitive loading. 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.
