Problems solved by technology

[0003] However, most of the covers have the problems of high reflection and large changes in transmission and reflection due to angle changes. When external light hits the cover, a certain proportion of reflected light will be formed. When the external light is reflected to the user The visibility of the display is reduced when
Especially when used outdoors, the stronger the external light, the stronger the reflected light, making it almost difficult for users to see the content displayed on the product itself

Embodiment 1

[0140] A three-dimensional concave cylinder array micro-nano texture template with a diameter of 200nm and a depth of 100nm on the surface is used as a transfer mold. The texture surface has an anti-adhesive effect and does not adhere to the cured transfer UV glue.

[0141] Polish one surface of the glass substrate. After polishing, transfer UV glue line on the edge side of the outer surface of the glass, and then place the transfer mold on the glue line substrate. The texture side of the mold faces the transfer UV Glue, the textured area of ​​the mold corresponds to the textured area of ​​the base material. Apply roller pressure on the outer surface of the transfer mold, and roll from one side of the dispensing line to the corresponding side, so that the UV glue is completely filled between the texture surface of the transfer mold and the surface of the substrate; among them, the UV glue is made of epoxy resin UV curing adhesive of ester system.

Abstract

The invention relates to a high-transmittance and low-reflection functional component and a preparation method and application thereof. The preparation method of the functional part comprises the following steps: providing a base material and a micro-nano texture template with a micro-nano size and a three-dimensional structure; transfer printing UV glue is applied to the base material; the micro-nano texture template is applied to transfer printing UV glue, a transition glue layer is prepared through UV curing, the micro-nano texture template is removed, and an intermediate is prepared; carrying out plasma etching on the intermediate by adopting an etching plasma source so as to remove the transition glue layer in a region to be etched on the surface of the base material, and etching a micro-nano structure on the surface of the base material; the antireflection coating is prepared on the surface of a base material with a micro-nano size and a three-dimensional structure by adopting a material with the emissivity of 1.0-2.0. The method has the advantages of being easy to operate, controllable in micro-nano structure morphology, low in cost, long-acting and capable of being applied on a large scale, and the prepared functional part has the advantages of being high in transmission and low in reflection and has wide application prospects.

Description

Technical field [0001] The invention relates to the technical field of material surface processing, and in particular to a high-transmission, low-reflection functional component and its preparation method and application. Background technique [0002] In recent years, touch screens have become more and more widely used in fields such as mobile phones and car displays. Touch screens, also known as "touch screens" and "touch panels," are devices that can receive input signals such as contacts. For inductive LCD devices, the surface of the touch screen is usually a cover (such as a glass cover). When the graphic buttons on the screen are touched, the tactile feedback system on the screen can drive various connecting devices according to pre-programmed programs. It replaces the mechanical button panel and creates vivid audio and video effects through the LCD screen. As the latest computer input device, the touch screen is currently the simplest, most convenient and natural way ...
