Abstract: The present disclosure provides a method for controlling a fingerprint identification circuit. The method is used for detecting fingerprint recognition units arranged in an array. A fingerprint recognition unit is connected to a fingerprint recognition circuit. The fingerprint recognition circuit includes a loop selection unit and a signal processing unit. The method includes: resetting the fingerprint recognition circuit to enable the loop selection unit to load a first driving voltage to a sensing electrode; and, controlling a state of the loop selection unit through a sequence signal control to enable the fingerprint recognition units arranged in an array to be in different working states.
