摘要： Provided are a threshold voltage compensation circuit of TFT and a method for the same, a shift register and a display device. The threshold voltage compensation circuit includes an input terminal, an output terminal connected to the source of the thin film transistor, a first resistor to a Kth resistor connected in series, and Kth connectable link and at least one first connectable link. Since a voltage dividing circuit having connectable links divides the voltage input to the source of the thin film transistor, such that the gate-source voltage of the thin film transistor can be changed by changing the voltage of the source of the thin film transistor when the voltage of the gate of the thin film transistor is maintained unchanged, so as to control a leakage current of the thin film transistor under a turn-off state, such that the thin film transistor can be turned off normally.
