Abstract

The invention relates to a transparent electric conductor and preparation method thereof. The transparent electric conductor comprises a transparent substrate, a first dielectric layer, a second dielectric layer, a first conductive layer and a second conductive layer. The first dielectric layer and the second dielectric layer are sequentially stacked on the transparent substrate. The first conductive layer and the second conductive layer are respectively embedded in the first dielectric layer and the second dielectric layer. The first conductive layer and the second conductive layer are insulated from each other, and the first conductive layer and the second conductive layer are formed by a metal mesh. In the first conductive layer and the second conductive layer, the grid line width of the metal mesh is between 0.2 microns to 5 microns, and distance between two adjacent metal grid lines is between 50 microns to 500 microns. Replacement of expensive indium tin oxide with metal and that etching and the bridging are not needed in the preparation process can save materials and simplify the preparation process. The grid line width of the metal mesh and the distance between the two adjacent metal grid lines can ensure a larger viewing area, so that the transparent electric conductor is low in cost and high in transmittance.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a transparent conductor and a preparation method thereof. Background technique [0002] A touch screen is an inductive device that receives an input signal from a touch lamp. The touch screen has endowed information interaction with a new look and is a very attractive new information interaction device. The development of touch screen technology has aroused widespread concern in the information media circles at home and abroad, and has become a rising high-tech industry in the optoelectronic industry. [0003] Currently, the indium tin oxide (ITO) layer is a crucial transparent conductor in touch screens. Although the manufacturing technology of the touch screen is developing rapidly. But taking the projected capacitive screen as an example, the basic manufacturing process of the ITO layer has not changed much in recent years. ITO coating and ITO patterning are always unavoida...
