Problems solved by technology

However, since the size of the touch panel is getting bigger and bigger, if the surface resistance of the first transparent conductor layer is too high, it is easy to generate noise when it is applied to a large-size touch panel.

Abstract

Provided are a low resistance transparent conductive laminated body, comprising a transparent optical adjustment layer, a silicon oxide layer and a transparent conductive layer, wherein monox is represented by SiOx (x is greater than 1.6 and smaller than 2.0). The thickness scope of the transparent optical adjustment layer is 50 nm-4000 nm, and a refractive index range is 1.58-1.70. The thickness scope of the transparent conductive layer is 20 nm-25 nm and a surface resistance value scope is smaller than 200 omega / sq. A scope of an absolute value of a difference value between the refractive index of the transparent substrate and the refractive index of the transparent optical adjustment layer is below 0.05. The low resistance transparent conductive laminated body generates no interference stripes; and when a low resistance patterned transparent conductive laminated body formed by the low resistance transparent conductive laminated body is applied to a touch panel, a user can not easily see patterned marks of the transparent conductive layer in observation, and the touch panel can obtain better display quality.

Description

technical field [0001] The invention relates to a low-resistance transparent conductive laminate for a touch panel, in particular to a low-resistance transparent conductive laminate comprising a transparent substrate, a transparent optical adjustment layer, a silicon oxide layer and a transparent conductive layer. Background technique [0002] In recent years, many convenient smart products have been launched on the market, such as smart phones, touch screens, touch panels, and e-books. With the introduction of these highly applied touch technologies, the use of the entire touch panel has been driven. And the touch panel is for example but not limited to a resistive touch panel or a capacitive touch panel. The touch panel is a transparent conductive laminate including a transparent organic polymer substrate and a transparent conductive film disposed on the transparent organic polymer substrate. [0003] The above-mentioned transparent conductive laminate can be further pat...
