Shift register units, display panels utilizing the same, and methods for improving current leakage thereof

A shift register unit having an input terminal and an output terminal, comprising:

• an input unit, in accordance with a first clock signal, configured to receive an input signal from the input terminal and output a switching control signal;
• at least one first transistor coupled to the input unit, wherein the gate of the first transistor is configured to receive the switching control signal, the drain of the first transistor is configured to receive a second clock signal, and the source of the first transistor is coupled to the output terminal;
• and at least one second transistor, wherein the gate and the drain of the second transistor are coupled to the output terminal, and the source of the second transistor is coupled to the input unit.
