Embodiment Construction

[0040] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0041] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a preparation method for a metal mesh. According to the preparation method, a latticed groove is formed in the surface of a substrate firstly, then a conductive metal film layer is formed on the surface of the substrate, furthermore, etching protection is carried out on an area located in the range of the groove, due to the fact that etching protection is carried out on the area in the range of the groove, when the conductive metal film layer is etched, the portion, located in the range of the latticed groove, of the conductive metal film layer can be reserved, therefore the metal mesh is obtained, it is clear that the metal mesh is obtained by wholly coating the surface of the substrate with the film layer firstly and then performing etching selectively without performing silver paste filling in a traditional technology, moreover, the maturity and reliability of a film coating process and an etching process are high, therefore, the preparation method for the metal mesh can effectively improve the reliability of the metal mesh, in addition, the preparation method for the metal mesh also can effectively reduce the preparation cost of the metal mesh and improve the production efficiency. The invention further provides a metal mesh sheet.

Description

technical field [0001] The invention relates to the technical field of photoelectric display, in particular to a method for preparing a metal grid and a metal grid sheet. Background technique [0002] In fields such as touch screens, transparent conductive films are widely used. The key structure in the transparent conductive film is the metal grid that plays a conductive role. At present, the metal grid of the transparent conductive film is formed by a filling process, including steps such as embossing grooves, filling conductive silver paste, filling black ink, and high-temperature sintering and curing. [0003] In order to ensure the filling effect, the silver powder in the conductive silver paste must be nanoscale. Therefore, the conductive silver paste needs to be specially developed for the transparent metal grid conductive film technology, which has the disadvantage of poor stability in addition to being expensive. Correspondingly, the scraper blade used for fillin...
