1. A control method for an optical fingerprint sensor and a touch controller, the optical fingerprint sensor comprising a plurality of pixels, each of the pixels having a first control signal line and a second control signal line, each of the pixels further coupled to a first voltage source line, a second voltage source line and a sensing line, the control method comprising:
configuring 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 to be floating when the touch controller is in a touch operation period.
