Cover plate structure

Technical Field

The utility model relates to a portable equipment field especially relates to an apron structure.

Background

At present, in order to achieve the effect of gradient color, a Physical Vapor Deposition (PVD) technique is generally used to plate a plurality of film layers of different materials and different thicknesses on the surface of a cover plate to form a film system, and the film system has different materials and different thicknesses of the film layers, so that the absorption, refraction, diffraction and reflection properties of visible light are different to generate iridescence with different colors. However, the multilayer film layers provided for realizing the gradient color are not insulated and have low resistivity, which greatly attenuates electromagnetic waves and affects signal transmission and reception of intelligent products.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. 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 the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, a cover plate structure of the present invention is schematically shown, including a protective layer 20, a substrate layer 30, an NCVM layer 40, and an ink layer 50. The protective layer 20, the substrate layer 30, the NCVM layer 40 and the ink layer 50 are sequentially arranged from top to bottom, and the thickness of the NCVM layer 40 is 30-50 nm, preferably 40 nm. The protective layer 20 is a high-transmittance anti-fingerprint AF film and is made of 980AF-3 materials, the base material layer 30 is made of glass materials, and the NCVM layer 40 can transmit light, so that the ink layer 50 is sprayed or silk-screened to set off the color of the NCVM layer 40. NCVM is also called discontinuous coating technique or non-conductive electroplating technique, the utility model discloses a target that NCVM layer 40 used is tin (Sn), indium (In), aluminium silicon (SiAl), and half light permeability control can be realized when NCVM layer 40 has metallic sense, embodies metallic sense and possesses light penetrability simultaneously promptly.
