Array substrate, display panel and display device

Abstract

The embodiment of the invention discloses an array substrate, a display panel and a display device. Including: a base substrate, a first metal layer, an interlayer dielectric layer, a second metal layer, an organic planarization layer and a third metal layer; the first metal layer forms a plurality of scanning lines in the display area, and does not form in the fan-out area Data connection leads; the second metal layer forms a plurality of data lines in the display area, and forms a plurality of data connection leads in the fan-out area; the third metal layer forms a plurality of data connection leads in the fan-out area; wherein, the data connection leads are adjacent to the display One end of the region is electrically connected to the data lines in one-to-one correspondence; two adjacent data connection leads are located in different layers, and the vertical projections on the base substrate are at least partially overlapped. The technical solution provided by the embodiment of the present invention can reduce the load difference on two adjacent data connection leads, and at the same time, can also reduce the height of the fan-out area.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to an array substrate, a display panel, and a display device. Background technique [0002] With the development of display technology, liquid crystal displays and organic light-emitting displays have become the two mainstream products in the display field. At the same time, consumers' performance requirements for displays are also constantly improving. [0003] The display usually includes a display area and a frame area surrounding the display area. The display area includes a plurality of scanning lines and a plurality of data lines intersecting each other, and a plurality of scanning lines and a plurality of data lines intersect to define a plurality of sub-pixel units; the frame area includes a lower frame area, the lower frame area includes a plurality of data connection leads, the data connection leads are used to electrically connect the driver ch...

Problems solved by technology

In the prior art, the data connection leads are usually located on the first metal layer (the film layer where the scan line is located) and the second metal layer (the film layer where the source and drain electrodes are located), wherein the coupling capacitance between two adjacent data connection leads is relatively small. Large, resulting in a large difference in the load on two adjacent data connection leads, affecting the quality of the display screen
