    Abstract: The present application discloses a gate drive circuit and a display panel. The gate drive circuit includes a plurality of cascaded gate drive units, in which by adopting a same complex clock signal for a pull-down control module, a maintaining module and a pull-down module, a N-th-stage gate drive unit can rapidly pull down a falling edge of a N-th-stage scan signal to the potential of a constant low voltage level signal and effectively reduces the time required to pull down the N-th-stage scan signal from high voltage level to low voltage level.

    Abstract: Embodiments of the present disclosure are directed to a display panel and a display device. The first fan-out wire in a first area is designed as a first portion of the first metallic layer and a second portion of a second metallic layer. The first portion of the first metallic layer is coupled to the second portion of the second metallic layer. The width of the first fan-out wire in the first area is less than the width of the fan-out wires in other areas. The distance between the first fan-out wires in the first area is less than the distance between the first fan-out wires in the other areas. While the impedance of the first fan-out wire is not increased or even reduced, the space occupied by the first fan-out wire is reduced.

    Abstract: The present application provides a display panel and a display device. The display panel includes a plurality of pixel units, wherein each of the pixel units includes a sub-pixel, the sub-pixel includes a first micro-LED chip, and in a top view, a gap is provided between adjacent ones of the first micro-LED chips; and a functional element disposed at the gap, wherein a function of the functional element is different from a display function of the sub-pixel, in order to improve integration of the display panel, increase an added value of the display panel, and save a space of the whole machine.
