Abstract

The invention provides a surface-capacitive touch panel and a manufacturing method thereof. The touch panel comprises a transparent substrate, a decorating layer, a capacitance sensing electrode layer, a metal routing pattern layer and a protective layer, wherein the decorating layer is formed on a surface of the transparent substrate; and the capacitance sensing electrode layer is formed on a first side of the transparent substrate. The metal routing pattern layer is formed on the capacitance sensing electrode layer, and a forming position of the decorating layer is substantially coincided with the metal routing pattern layer to cover metal routing. The protective layer is formed between the transparent substrate and the capacitance sensing electrode layer. According to the surface-capacitive touch panel and the manufacturing method thereof, the film thickness can be reduced, the film thickness uniformity is improved, and higher reliability and other efficacies can be realized.

Description

technical field [0001] The invention relates to a surface capacitive touch panel and a manufacturing method thereof. Background technique [0002] At present, the capacitive touch panel technology can be roughly divided into two types: projection type and surface type. Due to the limitations of the driving method, the surface capacitive touch panel cannot achieve the effect of multi-touch recognition, but it is simpler and cheaper than the projection type in terms of structure and manufacturing cost. [0003] figure 1 It is a schematic diagram of a conventional surface capacitive touch panel. Such as figure 1 As shown, the top surface and the bottom surface of the glass substrate 11 can be plated with a conductive coating 12, 13 respectively, the material of the conductive coating can be, for example, an indium tin oxide (IndiumTinOxide; ITO) film, and then a layer of screen printing The silver traces 14 are then coated with a hard coating layer 15 for isolation and prot...
