Conductive thin film

Abstract

The invention relates to a conductive thin film which comprises a substrate, a first hard coating, a second hard coating, a first refraction layer, a second refraction layer and a transparent conductive layer. The first hard coating and the second hard coating are arranged on the substrate sequentially. Component materials of the second hard coating comprise silicon. The first refraction layer, the second refraction layer and the transparent conductive layer are arranged on the second hard coating sequentially, and the transparent conductive layer covers a part of the second refraction layer. When light is shone on the transparent conductive layer through an incidence angle, the transparent conductive layer reflects the light through first reflectivity. When the light is shone on the second refraction layer through the incidence angle, the second refraction layer reflects the light through second reflectivity. The difference between the first reflectivity and the second reflectivity is smaller than a first threshold value. The conductive thin film can eliminate color developing difference between an etched area and an area which is not etched.

Description

technical field [0001] The present invention relates to a conductive film, in particular to a conductive film capable of eliminating color difference between etched and non-etched regions. Background technique [0002] With the advancement of production technology and its continuous expansion in various applications, electronic products are gradually providing more and more diversified functions and higher integrated usability to facilitate users' operations. For example, in order to provide users with more convenient and more direct control of electronic appliances, electronic information products are increasingly equipped with touch-sensitive display panels to replace traditional control buttons in the form of buttons. [0003] Currently, touch panels can be roughly classified into resistive, capacitive, infrared, and ultrasonic touch panels, among which resistive touch panels and capacitive touch panels are the most common products. As far as current applications are con...

[0005] However, the conductive film must go through yellow light developing and etching process, so as to obtain the circuit pattern on it, so as to shape the relevant driving circuit, but in the actual production process, the etching process will leave an etched surface on the panel. traces, such as the formation of a structure with a height difference on the transparent conductive layer; and in optical analysis, due to the large reflectivity difference between the etched part of the exposed glass substrate and the unetched transparent conductive layer, it will There is a significant drop in the spectrum, so it will cause unclear images or blocks in the user's vision, or there will be obvious boundaries, etc., which will cause a decline in the quality of electronic products.
