A capacitive touch screen is disclosed in the present invention, including: a transparent substrate, including a first surface and a second surface opposite to the first surface; a light-shield layer formed on the edge of the first surface of the transparent substrate, which forms a non-visible area; and a transparent polymer layer formed on the first surface, which is opposite to the first surface and covers the light-shield layer, a part of the transparent polymer layer covering the light-transmission area of the transparent substrate forms a sensing area, a surface of that is patterned to form a first meshed conductive trench, which is filled with a conductive material. The defined conductive trench reduces the scratching to the conductive material when the capacitive touch screen is in use, and the use of the trench structure reduces the covering area of the conductive material, the contact resistance and the cost.

Capacitive touch screen

A capacitive transparent conductive film comprises: a transparent substrate, comprises a first surface and a second surface which is opposite to the first surface; a light-shield layer, formed at the edge of the first surface of the transparent substrate, the light-shield layer forms a non-visible region on the first surface of the transparent substrate; and a polymer layer, formed on the first surface of the transparent substrate, and covering the light-shield layer, the surface of the polymer layer is patterned to form a meshed trench, the trench is filled with conductive material to form a sensing region on the surface of the polymer layer. The capacitive transparent conductive film can effectively protect the conductive material and has low cost and good conductivity. A preparation method of the capacitive transparent conductive film is also provided.
