Document Type and Number:
WIPO Patent Application WO/2020/062157
Kind Code:
A1
Abstract:
A foldable touch module, a touch screen and a terminal device in the technical field of touch screens. Existing touch modules are easily damaged or broken after being bent multiple times and are difficult to apply to devices such as a foldable mobile phone, and therefore provided is a foldable touch module, comprising upper and lower layers of patterned transparent conductive films (1), (2), and a transparent bendable optical adhesive (3) in the middle; the conductive films (1), (2) are manufactured by coating a silver nano wire (4) on a polyimide thin film (5), and the patterns are obtained by means of laser etching; the conductive films (1), (2) are provided thereon with bending zones (6), patterns within the bending zones (6) being led out from upper and lower edge wiring of the conductive films (1), (2). The silver nano wire (4) that has good conductivity and that is foldable is coated on the polyimide thin film (5) having high rigidity and excellent flexibility to manufacture the conductive films (1), (2) without having to print conductive silver paste wiring at the left and right sides of the bending zones (6), which may effectively prevent the wires from being damaged or broken during bending such that the described touch module has excellent bending capabilities.
