Abstract

The invention discloses an array substrate and a preparation method thereof, a display panel and a display device. Wherein, the array substrate includes a display area and a non-display area arranged around the display area, the non-display area includes a wire-drawing area, and the wire-drawing area includes a first arc-shaped boundary near the side of the display area, and the array substrate also includes first signal lines connected to each other and the first signal transmission line, the first signal line is located in the display area, and the first signal transmission line is located in the pull line area; along the first direction, the width of the first signal transmission line gradually increases; wherein, the first direction is the routing of the first signal transmission line direction, and point from the non-display area to the display area. The present invention provides an array substrate and a preparation method thereof, a display panel, and a display device. By setting the width of the first signal transmission line gradually increasing along the first direction, the space of the cable area is fully utilized, and the impedance of the first signal transmission line is reduced, thereby Reduce the risk of insufficient charging of the first signal line, and solve the problem of split screen at the edge of the display area.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to an array substrate and a manufacturing method thereof, a display panel, and a display device. Background technique [0002] With the development of display technology, full-screen technology has received more and more attention, and there are more and more electronic products with R corners (rounded corners). [0003] However, the existing full-screen display panel has the problem of screen splitting (uneven display) at the edge of the display area. Contents of the invention [0004] The invention provides an array substrate and a preparation method thereof, a display panel, and a display device, so as to solve the problem of screen splitting at the edge of a display area. [0005] In a first aspect, an embodiment of the present invention provides an array substrate, including: [0006] a display area and a non-display area arranged around the di...
