Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a shift register unit, a gate line driving device including the shift register unit, and a driving method for the shift register unit. Background technique [0002] In the field of display technology, a pixel array such as a liquid crystal display usually includes multiple rows of gate lines and multiple columns of data lines that are staggered. Wherein, the driving of the gate lines can be realized through an attached integrated driving circuit. In recent years, with the continuous improvement of the amorphous silicon thin film technology, the gate line driving circuit can also be integrated on the thin film transistor array substrate to form a GOA (Gate driver OnArray) to drive the gate line. [0003] Among them, the GOA composed of multiple shift register units can be used to provide switching signals for multiple rows of gate lines in the pixel array, thereby c...

Problems solved by technology

However, because the size of the transistor that pulls down the output of the shift register unit is generally large, the use efficiency is low, which is not conducive to reducing the circuit size and power consumption; The triggering of the shift register unit of the stage is completed by the signal output by the output transistor of the shift register unit of the present stage. Therefore, the load of the output transistor of the shift register unit of the present stage is relatively large, resulting in a signal output delay; in addition, if the output Failure of the transistor will not only lead to poor signal output to the gate line corresponding to the current stage, but also cause output failure of the gate line corresponding to the previous stage and the next stage
