Abstract

The invention applies to the technical field of touch, and provides a manufacturing method of a capacitive touch panel. The manufacturing method of the capacitive touch panel comprises the steps of sequentially arranging an SiO2 film layer and a transparent conductive film on a glass base plate; manufacturing a light sensitive glue pattern on the transparent conductive film; etching the transparent conductive film through the light sensitive glue pattern to form a transparent electrode, wherein the light sensitive glue pattern is remained; arranging a transition layer on the light sensitive glue pattern and the SiO2 film layer; removing the light sensitive glue pattern and the transition layer on the surface, and remaining the transition layer on the SiO2 film layer; coating a Cu film or a Cu alloy film on the transparent electrode pattern and the transition layer; etching the Cu film or the Cu alloy film; forming a Cu conductor around the transparent electrode pattern. The manufacturing method has the advantages that the Cu conductor and the SiO2 film layer are insulated through the transition layer, so that Cu elements are prevented from being dispersed to the SiO2 film layer, and as a result, micro short circuit of the transparent electrode can be prevented, the problem that the Cu material cannot be applied to the glass base plate can be overcome, the cost can be decreased, and the productivity and yield are improved.

Description

technical field [0001] The invention belongs to the field of touch technology, in particular to a capacitive touch panel and a manufacturing method. Background technique [0002] The structure of the capacitive touch screen is mainly to coat a layer of transparent ITO film conductor layer on the screen, and to plate narrow and long electrodes on the four sides of the touch screen to form a low-voltage AC electric field in the conductive layer. When touching the screen, a coupling capacitance will be formed between the finger and the conductor layer, and the current from the electrodes on the four sides will flow to the contact, and the current strength is proportional to the distance from the finger to the electrode, and the controller behind the touch screen will calculate the current. Proportion and strength, accurately calculate the position of the touch point. Because the surrounding electrodes are very thin, metal materials with low resistivity are required. MoAlMo or ...
