preparation example Construction

[0042]According to the preparation method of the touch panel according to the embodiment of the present invention, based on the etchable insulating layer, when preparing the electrode, the insulating layer at the non-electrode position is etched away, that is, the barrier of the nano-silver wire layer corresponding to the non-electrode position is removed, thereby , when the nano-silver layer is etched, the etching speed of the nano-silver layer is improved, which is equivalent to shortening the erosion time on the side of the signal line formed by the conductive metal layer, reducing the side erosion of the signal line, and effectively solving the problem of The side erosion of the conductive metal layer due to the slow etching of the nano-silver layer is beneficial to improving the precision of the preparation process and improving the stability of the performance of the touch panel.

[0043] For example, if figure 2 as shown, figure 2 (a)-(d) is the process flow of etchi...

Abstract

The invention discloses a touch panel and a preparation method thereof and electronic equipment. The preparation method of the touch panel comprises: providing a transparent conductive film, the transparent conductive film comprising a nano silver wire layer, an insulating layer and a conductive metal layer stacked in sequence; etching the conductive metal layer of the transparent conductive film according to the patterns of the electrode and the wiring so as to form a signal line of a wiring area; etching the transparent conductive film forming the signal line according to the electrode pattern, removing the insulating layer at a non-electrode position, and removing the nano silver wire layer at the non-electrode position so as to form an electrode in the visible area; and etching off the conductive metal layer at the visible area electrode. The method provided by the embodiment of the invention can effectively solve the problem of circuit lateral erosion of the conductive metal layer, and improves the process precision and the product performance stability.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for preparing a touch panel, a touch panel and electronic equipment. Background technique [0002] Silver nanowires (AgNW for short) have the characteristics of high light transmittance, good electrical conductivity and good mechanical properties, and are ideal materials for the preparation of flexible transparent conductive films. It is expected to replace the traditional ITO (Indium Tin Oxide, that is, indium tin oxide). However, during use, the phenomenon of electrocorrosion and silver migration is an important factor affecting its chemical stability and service life. For such problems, the usual solution is to add an insulating layer on the surface of the nano silver wire transparent conductive film Methods. [0003] However, in some traditional touch designs such as colloidal silver wire, laser colloidal silver, and photosensitive silver, copper is used to mak...
