Abstract

A method for manufacturing a single-layer capacitive touch screen, comprising the following steps: Step S1: providing a PMMA substrate; Step S2: surface treating the PMMA substrate; Step S3: low-temperature electroplating ITO conductive film on the PMMA substrate; Step S4: Making electrode patterns and conductive lines on the conductive film; step S5: forming and processing the PMMA substrate; and step S6: bonding FPC to the circuit interface end of the PMMA substrate. Compared with the prior art, the single-layer capacitive touch screen manufacturing method of the present invention uses PMMA material as the substrate, and utilizes low-temperature electroplating and low-temperature bonding technology in the processing technology to overcome the problem of the original PMMA material as the capacitive screen substrate. Problems that often occur in the processing and manufacturing process, the single-layer capacitive touch screen made of the PMMA material is easy to process, not easy to break, and has low cost.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing a capacitive touch screen, in particular to a method for manufacturing a single-layer capacitive touch screen. 【Background technique】 [0002] The general capacitive touch panel adopts a multi-layered structure of the touch sensor layer (English: Touch Sensor) under the cover glass (or PET film). Such a structure not only increases the design difficulty, And raising the cost is also time-consuming. Since the traditional projected capacitive touch panel must use 1-2 pieces of glass to make the touch sensing layer, plus a cover plate, resulting in a complex structure. Therefore, touch panel module manufacturers are actively integrating the touch sensor into the surface cover, hoping to reduce the cost of materials, and reduce the thickness and weight of the touch panel module. Therefore, the research and development personnel proposed the ultimate solution of capacitive touch, which is to use only a...
