Shift register unit, grid driving circuit and display device

Abstract

The invention discloses a shift register unit, a grid driving circuit and a display device. Specifically, the shift register unit comprises a pull-up control module, a pull-up module, a pull-down control module and a pull-down module; the pull-up module provides a first clock signal to a transmission signal output terminal according to a pull-up control signal and provides first direct-current supply voltage to a grid driving signal output terminal according to the pull-up control signal and the first clock signal, wherein the first clock signal is input by a first clock signal input terminal. Due to the fact that the first direct-current supply voltage is used as input of a transistor, used for outputting grid driving signals, in the pull-up module, the transistor has no capacity coupling effects, namely, due to the fact that high and low level conversion does not exist in the first direct-current supply voltage, stray capacitance generated by the transistor cannot be charged or discharged frequently, power losses are reduced and the problem that power consumption of a common shift register unit is high is solved.
