Embodiment Construction

[0020] figure 1 It is a structural diagram of a traditional PET substrate transparent conductive film, which includes a PET substrate (6) and SiO on its surface 2-x Dielectric optical film (7) and ITO film (8). Of which SiO 2-x The role of the dielectric optical film (7) is to prevent the impact of outgassing of the PET (6) and improve the firmness of the ITO film (8). This kind of transparent conductive film is used as an electrode, and the part that needs to be etched changes its structure into a PET substrate (6) and SiO on its surface. 2-x A dielectric optical film (7) having a reflectivity significantly different from that of the unetched portion.

[0021] figure 2 It is the structure of the transparent conductive material of the present invention, and it comprises PET base material (1), and the first layer optical film (2), the second layer optical film (3), the third layer optical film (4) deposited on its surface successively ) and ITO films (5). The PET (1) can...

Abstract

The invention discloses a transparent conductive material, comprising a polyethylene glycol terephthalate (PET) base material and four layers of optical film on the surface of the base material. The difference between the reflectivity of the transparent conductive material and the reflectivity of the transparent conductive material subjected to surface ITO (Indium Tin Oxide) etching is smaller or equal to 1.5%, and the square resistance and the transmissivity of the material are high.

Description

technical field [0001] The invention relates to a flexible transparent conductive material, which is used in fields such as touch screens and display panels. Background technique [0002] Tin-doped indium oxide (Indium Tin Oxide, referred to as ITO), is an n-type semiconductor material, due to its high electrical conductivity, high visible light transmittance, high mechanical hardness and chemical stability, it is a commonly used Transparent conductive materials are used in transparent electrodes of various products. In actual application, ITO first adopts the physical vacuum method to prepare an ITO film on a certain substrate, such as glass, polyethylene terephthalate (PET for short), and then etch the film into a specific substrate according to needs. pattern as an electrode. The ITO film based on PET has been widely used in recent years because of its softness. In the application of the ITO film of the PET substrate as an electrode, it is etched into a specific patter...
