Abstract
The present disclosure describes a shift register unit, an organic light-emitting display panel and a driving method. The shift register unit comprises a node potential controller and an output unit. The node potential controller comprises a first output end and a second output end. The output unit is configured to output, based on a first control signal from the first output end and a second control signal from the second output end, a first level signal or a second level signal. According to the solutions provided by the application, the potential of each node in the shift register unit is stable and controllable, and contributed to the avoidance of output logic execution problem in the shift register unit caused by unstable node potential when each control signal level of the shift register unit jumps.
