Abstract

The embodiments of the present application provide a shift register unit and a method for driving the same, a gate driving circuit, and a display apparatus. Here, the shift register unit includes a first controlling sub-circuit, a first voltage dividing sub-circuit, a charging and discharging sub-circuit, and an outputting sub-circuit. Here, an output signal of the outputting sub-circuit is controlled by the charging and discharging sub-circuit. A first input signal and a second input signal input at a first input signal terminal Forward and a second input signal terminal Backward electrically coupled to the charging and discharging sub-circuit are pulse signals.
