Abstract
The present application provides a driving circuit and a driving method for the same and a display device, relating to the field of display technology. The driving circuit includes an input module, an output module, a pull-up module, an adjustment module, a pull-down module, and a reset module. When the pull-up module pulls up the voltage of a first node and then the pull-up module performs a bootstrapping function, the voltage of the first node continuously increases, and the adjustment module enables a scanning signal input terminal to discharge to pull down the voltage of the first node.
