Abstract

The invention relates to the technical field of touch control, and especially relates to a conducting film manufacturing method, a touch control panel manufacturing method, and a touch control panel. The conducting film manufacturing method comprises the steps: S1, providing a transparent base material; S2, coating the transparent base material with a photoresist layer; S3, manufacturing a groove with the corresponding pattern on the photoresist layer, and solidifying the photoresist layer with ultraviolet light; S4, coating the interior of the groove with nano silver thread solution; S5, solidifying the nano silver thread solution in the groove, so as to form a nano silver thread conducting film.

Description

【Technical field】 [0001] The invention relates to the field of touch technology, in particular to a method for manufacturing a conductive film, a method for manufacturing a touch panel, and the touch panel. 【Background technique】 [0002] In capacitive touch panels of traditional smartphones, such as iphone, the material of the conductive film is usually indium tin oxide (referred to as ITO). ITO has high light transmittance and good conductivity, and is widely used as a conductive electrode material for touch panels and display panels. However, indium is an expensive metal material. Using ITO as the material of the conductive layer greatly increases the cost of the touch screen. Moreover, in the patterning process of the ITO conductive layer, the entire surface of the plated ITO film needs to be processed. Etching to form ITO patterns. In this process, a large amount of ITO is etched away, resulting in a large amount of precious metal waste and pollution, and the cost is h...
