Demultiplexer gate driver circuit and display panel

A demultiplexer gate driver circuit and a display panel are provided. The demultiplexer gate driver circuit aims at the problem that the output amplitude of the m sub-gate drive signals divided from the gate drive signal by the demultiplexer module is low, which results in a poorer All Gate On function, when the GOA circuit of the demultiplexer module is used to achieve the All Gate On function. The full-on control module is improved by connecting the full-on control module to the m sub-gate drive signals divided from the gate drive signal. The m sub-gate drive signals are directly controlled by the full-on control module to output the high potential at the same time, and there is only one threshold voltage consumption from the full-on control signal to the sub-gate drive signals. The effect of the All Gate On function is effectively improved.
