Zusammenfassung:	The present invention provides a control method for an optical fingerprint sensor and a touch controller. 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 the step of applying an anti-loading driving (ALD) signal on at least one of the first control signal line, the second control signal line, the first voltage source line, the second voltage source line and the sensing line when the touch controller is in a touch operation period.
