The invention relates to the technical field of display devices, and provides a
shift register, a drive device and a displayer. The
shift register provided by the invention comprises a valuation unit, a reset
control unit and a reset unit. The valuation unit is used for outputting a
signal to a
signal output end under the control of an input
signal and a second
clock signal; the reset
control unit of which one end is connected with the valuation unit is used for inputting a
control signal to the reset unit under the control of a first
clock signal and a low-level signal; and the reset unit is used for resetting the signal output end under the control of the
control signal and a high-level signal input by the reset
control unit. The
shift register provided by the invention can quickly charge the grid of a reset
transistor grid while valuating the output end, so that the
transistor can be turned off in time, a larger
transient current generated when the reset
transistor and a valuation transistor are switched on at the same time is avoided, the
power consumption is reduced and circuit elements are protected. The shift register also can reduce the influence of leakage current from an input tube, reduce the
power consumption and enhance the stability based on the output
voltage feedback and input tube double-grid technology.
