Shift register units, gate driver circuits and display devices
The present disclosure provides a bi-directional scanning gate driver and its shift register unit. The shift register unit comprises a shift trigger signal/reset signal input terminal (1), a reset signal/shift trigger signal input terminal (2), the first clock terminal (6) and an output terminal (8). The shift trigger signal/reset signal input terminal (1) and the reset signal/shift trigger signal input terminal (2) are coupled to one of the shift trigger signal and the reset signal. When it is switched between the forward shift and the reverse shift, the signals coupled to the shift trigger signal/reset signal input terminal (1) and the reset signal/shift trigger signal input terminal (2) are exchanged. The first clock terminal (6) is coupled to a clock signal for providing a driving level to the output terminal (8). The circuit of such a shift register unit is constituted of at least four transistors and one capacitor. The structure of the circuit of the present disclosure is simple and may solve the technical problem of coupling noise voltage generated by the clock signal.
