Abstract

The embodiment of the invention discloses a shift register, a gate drive circuit and a display panel, and is characterized in that a node voltage control module is arranged to control the voltage of a first node and a second node, and a first output module is arranged to output a first gate drive signal according to the voltage of the first node and the second node; and the second output module outputs a second gate driving signal according to the voltage of the first node and / or the second node, and the first gate driving signal is different from the second gate driving signal. Therefore, two different gate driving signals can be output through the same shift register, so that the frame of the display panel is reduced, and the user experience is improved.
