Abstract

The invention provides a flexible touch panel, a preparation method thereof, and a touch device, and relates to the field of electronic device preparation. The flexible touch panel includes a flexible transparent cover plate, a flexible transparent decorative plate and a Connect the sensor film layer of the circuit board. The flexible touch panel alleviates the technical problems of the flexible touch panel in the prior art, such as small bending range and low service life. Compared with the traditional touch panel, the flexible touch panel has a larger bending range and longer service life, which expands the application range of the flexible touch panel and improves the market of the flexible touch panel Competitiveness.

Description

technical field [0001] The invention relates to the technical field of electronic device preparation, in particular to a flexible touch panel, a preparation method thereof, and a touch device. Background technique [0002] With the advancement of technology and the improvement of human living standards, portable mobile devices, such as mobile phones, computers, tablet computers and wearable electronic devices, have become an indispensable part of people's lives, and people's demand for these devices is increasing ,Increasingly demanding. As the core components of the above-mentioned devices, ordinary hard touch panels can no longer meet the market's demand for curved devices, and flexible touch panels are gradually entering everyone's field of vision. If the flexible touch panel can be successfully mass-produced, it will not only greatly benefit the manufacture of a new generation of high-end smartphones, but also have a profound impact on the application of wearable device...
