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: An array substrate and a display panel are provided. The array substrate includes a plurality of recess-shaped light-shielding patterns. An oxide semiconductor layer is correspondingly formed in a recess of one of the light-shielding patterns. In comparison with increasing a plane area for improving light-shielding performance of the light-shielding patterns, an area of an orthographic projection of the recess-shaped light-shielding patterns on the array substrate is smaller. Therefore, an area of a light-transmitting region of the array substrate is greater, thereby increasing an aperture of the array substrate.

Abstract: The present disclosure provides a display panel and a display device. A distance from a surface of a first conductive adhesive layer close to a first pin, electrically connecting the first conductive pad and the first pin, to the substrate is different from a distance of a surface of a second conductive adhesive layer electrically connected to the second conductive pad and the second pin to the substrate, to compensate for a height difference caused by the partial warpage of the pins on the drive chip when binding a drive chip, so as to ensure that the drive chip can be well bonded to the display panel.
