Abstract
A shift register unit, a gate driving circuit, a driving method thereof and a display panel, wherein the shift register unit includes an input module, a pulling-down module, a control module, an output pulling-up module and an output pulling-down module. In the shift register unit, each module performs only a specified voltage pulling-up function or a specified voltage pulling-down function, and therefore it can be formed with only N-type TFTs or only P-type TFTs. As compared with the known CMOS LTPS GOA, the shift register unit and gate driving circuit has a simple structure, is easy to be implemented, has full functions, possesses high performance and reliability and the like, which are benefit for reduction of the cost along with the popularization and application of the CMOS LTPS GOA.
