Abstract

The invention relates to the technical field of display and provides a shift register unit. The shift register unit comprises an input module, a pull-up module, an output module, an auxiliary module,a pull-down module, a first storage capacitor and a second storage capacitor. The auxiliary module is connected with a first clock signal terminal, a second clock signal terminal, an input terminal and a first output terminal. A second storage capacitor is connected between the first node and the pull-up node; when the first storage capacitor and one or more elements in the pull-up module fail tofunction properly during actual production or when the shift register unit is operated, the second storage capacitor and the auxiliary module cooperate to enable the normal operation of the shift register unit, thereby enabling the display panel to be displayed normally. The second storage capacitor and the auxiliary module cooperate to enable the shift register unit to function normally.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a shift register unit, a gate drive circuit and a display device. Background technique [0002] With the pursuit of low-cost flat panel display devices and the improvement of manufacturing processes, flat panel display devices increasingly adopt gate drive technology, and the gate drive circuit may include multiple shift register units. [0003] However, in the actual production process, one or more of the TFTs (thin film transistors) and storage capacitors in the shift register unit are prone to various defects, making the shift function impossible, which can lead to the entire panel Cannot display properly. [0004] Therefore, it is necessary to propose a new shift register unit, gate drive circuit and display device. [0005] The above-mentioned information disclosed in the background section is only used to enhance the understanding of the background of the present invention,...
