Problems solved by technology

[0008] The internal structure of the GOA unit and the layout structure of the via holes are very different in the preparation process of the forward scanning array substrate and the reverse scanning array substrate. When the mask plate process is used for manufacturing, basically every mask The boards are not the same, which leads to problems such as poor compatibility of production process, high production cost and high design cost.

Abstract

An array substrate, a display device, and a fabrication method of the array substrate. The array substrate comprises two or more GOA units (2) and an STV signal line. A transmission channel between two adjacent GOA units (2) is formed of a via hole and a gate line metal layer or a source / drain metal layer; a front-side via hole region (3) and a back-side via hole region (4) are provided on the array substrate, the front-side via hole region (3) is used to dispose a front-side via hole for forming a front-side transmission channel connecting an output end of the mth GOA unit (2) and an input end of the (m+1)th GOA unit (2), and the first GOA unit (2) is provided with a connecting point connected to the STV signal line; the back-side via hole region (4) is used to dispose a back-side via hole for forming a back-side transmission channel connecting an output end of the (m+1)th GOA unit (2) and an input end of the mth GOA unit (2), and the last GOA unit (2) is provided with a connecting point connected to the STV signal line, wherein m is an integer not less than 1. The array substrate is manufactured in low cost and has a desirable drive effect.

Description

technical field [0001] The present invention relates to the field of display, in particular to an array substrate, a display device and a method for preparing the array substrate. Background technique [0002] GOA——(GateDriverOnArray) Gate Driver on Array Substrate [0003] GOA technology integrates the gate drive on the array substrate, thereby omitting additional drivers such as flexible circuit thin film COF (ChipOnFilm) on the edge of the substrate, which is conducive to the miniaturization of the array substrate, and reduces the cost of materials and manufacturing. The cost of the process. [0004] One GOA unit corresponds to one gate line on the array substrate. Specifically, the output terminal of each GOA unit is connected to one gate line, and is also connected to the input terminal of the GOA unit connected to the next scanning gate line. [0005] There are two existing scanning methods: [0006] The first type: scan in the forward direction, that is, scan from ...
