Problems solved by technology

[0003] For 43-inch ADS (Advanced Hyper-Dimension Switching) display products and 18.5-inch HADS (High Aperture Ratio Advanced Hyper-Dimension Switching) display products, the deep hole density of 43-inch ADS display products is less than that of 18.5-inch HADS display products The deep hole density of the product, wherein, the deep hole is a via hole that penetrates at least two layers of insulating layers. Since the deep hole is prone to depression, when the alignment film is coated on the array substrate of the MMG product, the alignment film is easy to be in the deep hole. Diffusion is prone to unevenness, resulting in the problem of display Mura (unevenness) in the final display product

Abstract

The invention provides an array substrate mother board, a manufacture method and a display device thereof, and belongs to the technical field of display. The manufacture method of the array substrate mother board at least comprises: a film pattern of a first display product is formed on a first area of the substrate, a film pattern of a second display product is formed on a second area of the substrate, the deep hole density of the first display product is greater than the deep hole density of the second display product, a deep hole is a via hole which passes through at least two insulting layers, the manufacture method comprises the steps: before a second conductive pattern is formed on the insulting layers, the thickness of the insulting layers of the first area is reduced, and the second conductive pattern is connected with a first conductive pattern which is below the insulting layers through passing through a via hole structure of the insulting layers. According to the technical scheme of the invention, when film patterns of different display products are formed on the substrate, adverse Mura phenomena can be avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate motherboard, a manufacturing method thereof, and a display device. Background technique [0002] MMG (Multi Mode Group, multi-display mode group) product is to form two or more graphics of display products on the same substrate at the same time, which can improve the utilization rate of the substrate and reduce the input cost. Currently as figure 1 The 43MMG product shown has been mass-produced. The 43MMG product forms the graphics of a 43-inch ADS display product and an 18.5-inch HADS display product on the same substrate. [0003] For 43-inch ADS (Advanced Hyper-Dimension Switching) display products and 18.5-inch HADS (High Aperture Ratio Advanced Hyper-Dimension Switching) display products, the deep hole density of 43-inch ADS display products is less than that of 18.5-inch HADS display products The deep hole density of the product, wherein, the d...
