摘要

一种电极结构及其制作方法、使用此电极结构的触控元件及触控显示器。电极结构包括基板以及设置于基板上的图案化导电层。图案化导电层具有平均高度h1以及表面粗糙度h2，其中平均高度h1包含表面粗糙度h2，且0.01h2/h10.2。图案化导电层包括曲线以及接合点，其中至少三条曲线从同一个接合点分别朝向不同方向延伸，且每一曲线是由边长为D的正多边形之外切圆的1/n圆弧所形成，其中外切圆的半径r由公式r=(D/2)sin(180/n)定义，曲线长S=2 π r/n，且500d 2 /h25000，其中d为每一曲线的线宽，n为正多边形的边数。 An electrode structure, method of fabricating the same, touch element and touch display using the electrode structure are provided. The electrode structure including a substrate and a pattern conductive layer disposed on the substrate is provided. The pattern conductive layer has an average height h1 and a surface roughness h2 included by the average height h1, wherein0.01h2/h10.2. The pattern conductive layer includes multiple arc lines and multiple joints, wherein at least three arc lines from a same joint extend to different directions, and each arc line is 1/n of an externally tangent circle formed by a regular polygon with side length D, wherein a radius of the externally tangent circle is defined by the formula: r=(D/2)sin(180/n), and length S of the arc line matches the formula: S=2 π
