Abstract
A display panel including an array substrate and a COF substrate is provided. The COF is provided with a plurality of welded lead lines. The array substrate includes a metal layer disposed on a surface of the substrate, a silicon nitride layer disposed on a surface of the metal layer, and a plurality of terminal wires disposed in a spaced arrangement in a welding region on a surface of the second silicon nitride layer. The welding region between the adjacent terminal wires is provided with through holes, which expose the metal layer. The risk of corrosion and breakage of the welded lead lines on the COF substrate is effectively reduced.
Claims20
A display panel comprising an array substrate and a COF substrate provided with a plurality of welded lead lines, wherein
- the array substrate comprises:
- a substrate;
- a first metal layer disposed on a surface of the substrate;
- a first silicon nitride layer disposed on the first metal layer;
- a second metal layer disposed on the first silicon nitride layer;
- a second silicon nitride layer disposed on the second metal layer;
- and
- a plurality of terminal wires disposed in a spaced arrangement in a welding region on a surface of the second silicon nitride layer, the welding region being a region where the terminal wires are connected with the welded lead lines,
- wherein each of the terminal wires is laminated and connected with a corresponding one of the welded lead lines on the COF substrate, and portions of the welding region between the adjacent terminal wires are provided with through holes which expose the metal layer.
A manufacturing method for a display panel, which has an array substrate and a COF substrate provided with a plurality of welded lead lines, comprising steps of:
- providing a substrate, forming a metal layer and a silicon nitride layer on the substrate successively;
- disposing a plurality of terminal wires in a spaced arrangement in a welding region on a surface of the silicon nitride layer on the substrate, which is a region where the terminal wires are connected with the welded lead lines;
- forming through holes by through hole etching in the welding region between the adjacent terminal wires, so that the through holes exposes the metal layer;
- and
- laminating and connecting each of the terminal wires with a corresponding one of the welded lead lines.
