Abstract

The invention provides a capacity touch panel employing a copper-plated conductive substrate, and belongs to the field of capacity touch panels. The capacity touch panel comprises a cover lens arranged outmost, a sensor bonded with the cover lens and an LCM (liquid crystal module) attached on the inner side of the capacity touch panel. The sensor is manufactured by processes of firstly, sputtering copper foil on the conductive substrate through a film coating process; secondly, forming a copper film signal line graph on the conductive substrate by performing operations of exposure, development and etching on a copper plated film by the aid of a dry film photoresist; thirdly, forming a transparent conductive film graph with the copper film signal line graph on the conductive substrate with the copper film signal line graph by operations of exposure, development and etching; and fourthly, cutting to obtain the sensor. The capacity touch panel employing the copper plated conductive substrate has the advantages that raw materials and processing cost can be reduced, production efficiency can be increased, and productivity can be improved.

Description

technical field [0001] The invention relates to the field of capacitive touch screens, in particular to a capacitive touch screen using a copper-plated conductive substrate. Background technique [0002] Touch screens are composite touch screens used in electronic products such as mobile phones, e-books, and digital cameras, among which capacitive touch screens are the most commonly used type of touch screens. [0003] The capacitive touch screen uses the current induction of the human body to work. The capacitive touch screen is usually a four-layer composite glass screen. The inner surface and interlayer of the glass screen are each coated with a layer of ITO (coated conductive glass), and the outermost layer is A thin layer of silica glass protective layer, ITO coating as the working surface, four electrodes are drawn from the four corners, and the inner layer of ITO is the shielding layer to ensure a good working environment; when the user's finger touches the capacitive...
