Abstract
A flexible conductive film and its manufacturing method are provided. A flexible touch screen and a flexible touch display panel including the flexible conductive film are also provided. The manufacturing method of a flexible conductive film includes: providing a first substrate; applying a first conductive metal ink on the first substrate and forming a first conductive metal pattern; applying a polyimide varnish on a surface of the first substrate having the first conductive metal pattern; soaking the first substrate in deionized water after the polyimide varnish has been solidified; and detaching the solidified polyimide varnish and the first conductive metal pattern from the first substrate to obtain the flexible conductive film. The flexible conductive film prepared can be used in a flexible touch screen and a flexible display panel to improve the adhesion of nanosilver material to a flexible substrate, and to improve its stability of mechanical strength.
