Claim:
1. A shift register unit comprising: an access control module for controlling access of an input signal and a reset signal, the access control module comprising a depletion field effect transistor; a shift register module for outputting the accessed input signal or reset signal under the driving of a clock signal; the shift register unit further comprising: a connection control module arranged between the access control module and the shift register module for blocking the connection between the access control module and the shift register module when the shift register module performs outputting, wherein the connection control module comprises a sixth switch element, a seventh switch element, an eighth switch element and a third capacitor; a second end of the sixth switch element is connected with a first end of the eighth switch element and a first end of the third capacitor; a second end of the seventh switch element is connected with a second end of the third capacitor; a first end of the sixth switch element is connected with the shift register module, a second end of the eighth switch element is connected with the access control module; the clock signal comprises a first clock signal and a second clock signal, the first clock signal is connected to a control end of the seventh switch element, the second clock signal is connected to control ends of the sixth switch element and the eighth switch element; a first end of the seventh switch element is connected with the low level working voltage line.
