The shifting register unit comprises a first grid electrode driving control node control module, a second grid electrode driving control node control module, a grid electrode driving signal output module, a first light-emitting control node control module, a second light-emitting control node control module and a light-emitting control signal output module, wherein the first light-emitting control node control module is used for controlling an electric potential of a first light-emitting control node to be a first electric potential under the control of a first grid electrode driving control node at an input phase and an output phase; and the second light-emitting control node control module is used for controlling the electric potential of a second light-emitting control node to be the first electric potential under the control of a light-emitting control signal at an output cutting-off keeping phase. According to the shifting register unit, the driving method, the grid electrode driving circuit and the display device, provided by the invention, the problem in the prior art that the shifting register unit which can provide a low-pulse grid electrode driving signal and a high-pulse light-emitting control signal at the same time, and comprises relatively few signal lines and transistors cannot be provided can be solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a shift register unit, a driving method, a gate driving circuit and a display device. Background technique [0002] In the field of display, in order to continuously improve the display screen, high ppi (Pixels Per Inch, pixel density), narrow border display has become a research hotspot. However, with the increase in the number of pixels, the number of rows that the gate drive circuit needs to scan in one frame time increases, and when the size of the display screen remains unchanged, the area of ​​the layout reserved for each row of shift register units gradually decreases. , In addition, the requirement of a narrow border makes the requirements of each row of shift register units more stringent, so a shift register circuit with a simple circuit structure and a small number of transistors is very necessary. And the prior art cannot provide a shift register unit includ...
