Problems solved by technology
[0008] However, the defect of the above-mentioned HC substrate 10-based shadow removal process is that the thickness of the coating is very large, and the total thickness of the coating in the three-layer basic form is close to 90nm, which is still the thinnest solution.
Since the coating efficiency is most affected by the thickness of the coating, the production speed of the whole scheme is relatively low, and its disappearing effect is: the transmittance difference ΔT in the wavelength range of 360-740nm can only reach about 1.3%, and the reflectance difference ΔR can only reach about 1.0%

Embodiment Construction
[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings. Wherein, the same parts adopt the same reference numerals.
[0027] based on figure 1 In the prior art, the defect of the ITO transparent conductive film obtained by using double HC substrate 10, an improved scheme is proposed for the above-mentioned deficiency, and the improved scheme can use the raw material substrate to be coated with a refractive index matching layer , IM layer) PET substrate. Such as figure 2 Shown, what it shows is the structure schematic diagram of the above-mentioned improved ITO transparent conductive film based on the PET base material with IM layer, hereinafter this PET base material with IM layer is called IM base material, this IM base material It can be obtained through commercial purchase. As sh...

Abstract
The invention provides an ITO transparent conducting thin film. The ITO transparent conducting thin film comprises IM base materials, the IM base materials are composed of a layer of PET base materials and an IM layer which coats a first side face of the PET base materials, wherein the refractive index of the IM layer is larger than 1.6, and a first low refractive layer, a second high refractive layer, a third low refractive layer and an ITO transparent electrode layer are sequentially plated above the IM layer of the IM base materials. According to the ITO transparent conducting thin film, existing HC base materials are replaced with the IM base materials, optimization and modification of the cost and structure are combined, the lower thickness, better display luminance and color expression are obtained, and the unexpected shadow elimination effect which is far better than the prior art is achieved.
Description
technical field [0001] The present invention relates to an optical conductive film that can be used on display accessories such as capacitive touch panels, and in particular to an ITO transparent conductive film that can be used for the above purpose. Background technique [0002] Tin-doped indium oxide (Indium Tin Oxide, ITO), as an ITO transparent conductive film prepared from semiconductor materials, has been widely used in many aspects such as solar cells and display devices (such as touch panels). Conventionally, the so-called conductive glass formed by forming an ITO electrode layer on glass has poor flexibility and processability because the base material is glass. In recent years, the ITO transparent conductive film based on PET (polyethylene terephthalate) has been widely used in the field of touch panels due to its advantages of good flexibility, excellent processing performance, and light weight. [0003] The ITO transparent conductive film needs to form an elect...
