一种双导电层结构的电容式触摸屏
摘要：
本实用新型公开一种双导电层结构的电容式触摸屏，包括玻璃基板(1)，玻璃基板(1)的上表面设有ITO导电膜层(2)，所述玻璃基板(1)的下表面设有两行以上的Metal-mash金属网格(4)，每行Metal-mash金属网格的一端均连接有金属走线(5)，金属走线(5)沿玻璃基板下表面的侧部汇总到柔性线路板连接区(6)；所述Metal-mash金属网格(4)与金属走线(5)共同构成金属网格导电膜层(3)；采用Metal-mash金属网格代替原先Y方向的ITO层，从而将传统DITO的三层导电层结构改变为双导电层结构，结构简单，使用黄光工艺就可同时对Metal-mash金属网格与金属走线进行制作，无需贴保护膜，简化了制作工艺，同时Metal-mash金属网格也能够增强导电性能。
摘要（英）：

The utility model discloses a capacitive touch screen of a double-conducting-layer structure. The capacitive touch screen comprises a glass substrate (1), and an ITO conducting film layer (2) is arranged on the upper surface of the glass substrate (1); two or more rows of Metal-mash metal meshes (4) are arranged on the lower surface of the glass substrate (1), one end of each row of Metal-mash metal meshes is connected with a metal wire (5), and the metal wires (5) are collected to a flexible circuit board connecting area (6) along the side portion of the lower surface of the glass substrate; a metal mesh conducting film layer (3) is jointly formed by the Metal-mash metal meshes (4) and the metal wires (5); the Metal-mash metal meshes are adopted to replace an ITO layer in the original Y direction, and therefore a three-conducting-layer structure of a traditional DITO is changed into the double-conducting-layer structure. The capacitive touch screen is simple in structure, the yellow light technology is used for manufacturing the Metal-mash metal meshes and the metal wires at the same time, a protection film does not need to fit the screen, the manufacturing technology is simplified, and meanwhile, the Metal-mash metal meshes can be used for improving the conducting performance.
