Abstract

The invention provides an array substrate, a display panel and a display device, and the array substrate comprises a substrate which is provided with a display area and a non-display area; the pixel unit is arranged in the display area; the driving chip is arranged in the non-display area, a wiring area is formed between the driving chip and the display area, and the wiring area comprises a center wire area and fan-out areas arranged on the two sides of the center wire area respectively; the fan-out structure is arranged in the wiring area so as to electrically connect the driving chip with the pixel units; the fan-out structure comprises a center wire arranged in the center wire area and a plurality of fan-out wires arranged in the fan-out area. The length of the central lead is smaller than that of each fan-out lead; the fan-out wire comprises a first metal layer, a second metal layer and an insulating layer located between the first metal layer and the second metal layer. The insulating layer is provided with a conductive hole, and the first metal layer and the second metal layer are conducted in parallel through the conductive hole. The array substrate can reduce the delay degree of signal transmission so as to improve the display effect of the display area.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to an array substrate, a display panel and a display device. Background technique [0002] The display substrate includes a display area and a driving circuit area (or called peripheral circuit area, peripheral circuit area); wherein, the driving circuit area is provided with a driving circuit to output signals; the display area is provided with a display structure layer to display the picture; two Wires for transmitting corresponding signals to the display area are provided between the two areas. [0003] In order to increase the area of ​​the display area, the wires located between the two areas are designed to be concentrated toward the drive circuit area with a smaller area, so that the wires located between the two areas are gathered into a fan-like structure, the area is It is the so-called fan-out area (ie Fan-out). [0004] In the fan-out area, due t...
