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

The invention discloses an array substrate, a display device and a manufacturing method of the array substrate. The array substrate comprises more than two GOA (gate driver on array) units and STV (start vertical) signal lines. A transmission path between every two adjacent GOA units is composed of via holes and a grid line metal layer or a source leak metal layer. The array substrate is provided with forward via hole areas and reverse via hole areas, wherein the forward via hole areas are used for forming forward via holes of forward transmission paths connecting an output end of the mth GOA unit with an input end of the mth+1 GOA unit, and the first GOA unit is provided with connecting points connected with the STV signal lines. The reverse via hole areas are used for forming reverse via holes of reverse transmission paths connecting an output end of the mth+1 GOA unit with an input end of the mth GOA unit, and the last GOA unit is provided with connecting points connected with the STV signal lines, wherein the m is an integer not smaller than 1. The array substrate, the display device and the manufacturing method of the array substrate have the advantages of low manufacturing cost and good driving 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 - (Gate Driver On Array) gate drive on the array substrate [0003] GOA technology integrates the gate drive on the array substrate, thereby omitting additional drivers such as flexible circuit thin film COF (Chip On Film) on the edge of the substrate, which is conducive to the miniaturization of the array substrate and reduces material costs. and manufacturing costs. [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 the end near the ...
