Example Embodiment
[0049] Example 1
[0050] figure 1 It is a functional block diagram of the shift register unit provided by Embodiment 1 of the present invention; please refer to figure 1 , The shift register unit provided in this embodiment includes an input module 1, an input terminal Out_N-1, an output module 2, an output terminal Out_N, a first clock terminal CKBL, a first reset module 3, a second reset module 4, and a pull-down module 5. , The second clock terminal CLK, the first storage module 6, the pull-up node PU, the pull-down node PD, and the interval module 7; where:
[0051] The input module 1 is connected to the input terminal Out_N-1, the first voltage terminal CN and the pull-up node PU, and is used to provide the signal of the first voltage terminal CN to the pull-up node when a valid signal is input at the input terminal Out_N-1 PU.
[0052] The output module 2 is connected to the pull-up node PU and the first clock terminal CKBL for outputting the signal on the first clock termina...
Example Embodiment
[0077] Example 2
[0078] Figure 5 This is a flowchart of the driving method of the shift register unit provided by the second embodiment of the present invention, please refer to Figure 5 , The driving method of the shift register unit includes the following steps:
[0079] S11, input stage: the input terminal inputs a valid signal, and the voltage at the first voltage terminal is provided to the pull-up node to charge the pull-up node; the pull-up node is an effective signal, so that the pull-down node and the second voltage terminal are connected to the pull-down node Discharge.
[0080] S12, the output stage: the pull-up node is floating, and the first storage module boots; the pull-up node is a valid signal so that the signal on the first clock terminal is provided to the output terminal; the pull-down node is kept discharged.
[0081] S13, the first reset stage: the reset terminal inputs an effective signal, so that both the pull-up node and the output terminal are connected...
Example Embodiment
[0085] Example 3
[0086] An embodiment of the present invention also provides a gate driving circuit, which includes a plurality of cascaded shift register units, and the shift register unit is the shift register unit described in Embodiment 1 above. The composition and driving method of the shift register unit have been described in detail in the above embodiment 1 and embodiment 2, for details, please refer to the content in the above embodiment 1 and embodiment 2, which will not be repeated here.
[0087] Wherein, the gate driving circuit may be an N-type gate driving circuit or a P-type gate driving circuit.
[0088] By adopting the above-mentioned shift register unit in the gate driving circuit, it is possible to improve the poor stability of GOA driving, which is beneficial to improve the yield of the display panel.
