<p>The embodiment of the present disclosure relates to a technical field of liquid crystal display, and particularly, to a gate driver on array, a shifting register and a display screen. The gate driver on array comprises: a first TFT, a second TFT, a third TFT, a fourth TFT, a capacitor and a pulling-down module, the pulling-down module is connected among a first clock signal input terminal, a second clock signal input terminal, a first node and an output terminal, and is connected with a low voltage signal terminal, for maintaining the first node and the output terminal being in a low level during a non-operation period of the gate driver on array. Thus, the gate driver on array may achieve a bidirectional scan by designing the functions of the input terminal and the reset terminal in the gate driver on array as being implemented symmetrically, without changing a charging-discharging characteristic of nodes, which ensures a reliability and stabilization of the circuit.</p> |
