Abstract: The present disclosure provides a shift register circuit and a method for driving the same, a gate driving circuit, and a display apparatus. The shift register circuit comprises an input module, configured to pull up a potential at a first node; an output module, configured to pull up a potential at an output when the potential at the first node is at a high level; a pull-up module, configured to periodically pull up a potential at the second node by using current from a high-level bias voltage line; a reset module, configured to pull down the potential at the first node under the control of a signal; and a pull-down module, configured to continuously pull down the potential at the second node before the potential at the first node is pulled down, and pull down potentials at the first node and the output when the potential at the second node is at a high level.
