Abstract

The invention relates to an array substrate, comprising a substrate; an external wiring formed on the substrate; the external wiring includes an external section and a line change section located inside the external section; an inorganic film layer covers the external wiring On the line; the inorganic film layer is provided with a via hole for partially leaking the line change section, and a groove for leaking the outer connection section; and a metal layer, formed on the inorganic film layer; the metal layer includes a plurality of metal wires; The metal trace is electrically connected to the wire-changing segment through the via hole. In the above-mentioned array substrate, there is no inorganic film layer above the outer section, so that the inorganic film layer is prevented from being squeezed on the outer section during bending, the stress is reduced, and the outer section is prevented from breaking. The invention also provides a preparation method of the array substrate and a display screen.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate, a preparation method thereof, and a display screen. Background technique [0002] The display screen includes a display area (AA area) and a non-display area (non-AA area). In order to achieve certain functions, the non-display area is required to be bendable. For example, in order to achieve a narrow frame, the non-display area is bent to the back of the screen, thereby reducing the width of the frame. [0003] However, in the current display screen, during the bending process of the non-display area, the film layer in the non-display area breaks, which in turn causes the metal wires to break easily, resulting in a defective screen body. Contents of the invention [0004] Based on this, it is necessary to provide an array substrate that is less likely to cause breakage of the metal wires to solve the problem that the metal wires are easily broken in the p...
