Abstract: 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.

Abstract: A MOG circuit and a display panel are provided. The MOG circuit controls the current-stage MOG circuit through the first node signal to block the input of the MUX signal. At the same time, the MOG circuit controls the current-stage MUX circuit through the second node signal such that the voltage level of the scan signal is pulled down to the voltage level of the first low voltage level signal. In this way, all the scan signals could satisfy the turn-off stage while the MUX circuit has a lower loading capability.

Abstract: The present disclosure provides a display panel. At least two de-multiplex control signal output lines of a de-multiplex circuit respectively output a first de-multiplex control signal and a second de-multiplex control signal. A falling edge of a scan signal of a scan driving circuit occurs earlier than a falling edge of the second de-multiplex control signal. The present disclosure can reduce interference on image displayed by a pixel unit caused by pulse signals of a capacitance formed by the de-multiplex control signal output lines and a data signal output line.
