Abstract

The invention relates to a method for manufacturing a silver paste circuit in a touch display product and the silver paste circuit, and the method comprises the steps: S1, printing a layer of insulating ink on an inductor substrate of the touch display product, and carrying out the solidification of the insulating ink, and forming an insulating ink circuit pattern layer; s2, printing silver pasteon the insulating ink circuit pattern layer and performing curing to form a silver paste circuit layer; and S3, printing a layer of insulating ink on the silver paste circuit layer and within an externally expanded preset area range, and performing curing to form an insulating ink protection layer. Silver paste is printed on the bottom-layer insulating ink; a layer of insulating ink is printed onthe silver paste; the silver paste is coated in the two layers of insulating ink; because the bottom-layer insulating ink is printed in a circuit state, the upper-layer insulating ink can better blockthe migration of silver ions, and meanwhile, the silver ions cannot migrate through the surface of the base material during migration, but an insulating oil groove is formed, so that the short-circuit difficulty between silver paste circuits is greatly increased, and the problem of short-circuit failure of a product caused by silver ion migration can be solved.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a method for manufacturing a silver paste circuit in a touch display product and the silver paste circuit. Background technique [0002] There are conductive lines on the sensors of the touch screen, and the commonly used materials for the conductive lines are: transparent ITO (indium tin oxide), silver paste, molybdenum aluminum molybdenum, etc. Silver paste is often used for edge leads on touch screen sensors due to its low cost, good conductivity, high adhesion to substrates, easy pattern processing, and high stability. However, when applying silver paste lines, due to Due to the inherent characteristics of silver paste, after the silver paste line is energized, especially in the case of direct current, silver ion migration is easy to occur. After silver ion migration occurs during the application process, it will cause a short circuit in the line, so that the product will fail. ...
