This disclosure discloses a shift register, a method for driving the same, a gate driver circuit, and a display device. The shift register includes an input circuit, a reset circuit, a first control circuit, a first output circuit, and a second output circuit, where the first output circuit includes two output channels, where one channel is that under the joint control of signals of a first clock signal terminal and a first node, a signal of a first clock signal terminal is provided to a drive signal output terminal of the shift register, and the other channel is that under the joint control of signals of the second clock signal terminal and the first node, a signal of a second clock signal terminal is provided to the drive signal output terminal, and the first output circuit cooperates with the other four circuits so that these two channels can operate alternately to thereby avoid current from flowing through only one of the channels so as to improve the service lifetime of the shift register. 1. A shift register , comprising:an input circuit configured to provide a first node with a signal of an input signal terminal under the control of the input signal terminal;a reset circuit configured to provide the first node with a signal of a reference voltage signal terminal under the control of a reset signal terminal;a first control circuit configured to control a level at the first node, and a level at a second node;a first output circuit configured to provide a drive signal output terminal of the shift register with a signal of a first clock signal terminal under the joint control of the signal of the first clock signal terminal and a signal of the first node, and to provide the drive signal output terminal with a signal of a second clock signal terminal under the joint control of the signal of the second clock signal terminal and the signal of the first node, wherein the signal of the first clock signal terminal and the signal of the second clock signal terminal have ...
