Abstract

The invention discloses a full flexible transparent touch control system which comprises two flexible transparent conducting layers, an insulation isolation dot matrix layer and a periphery conductingelectrode. The flexible transparent conducting layers mainly comprise a transparent conducting film formed by random lap joint of metal nanowires into grids; the insulation isolation dot matrix layeris located between the two flexible transparent conducting layers; an insulation isolation dot matrix is attached to the transparent conducting film of any flexible transparent conducting layer or manufactured on an independent transparent flexible conducting substrate; and two linear electrodes are fabricated on the insulation isolation dot matrix layer substrate and the other transparent conducting film to be connected with peripheral equipment. The hardware system is stable in structure, flexible and variable in configuration and good in flexibility, meets requirements of different performance preferences, and is applicable to touch control instruments in bending and vibration service environments and an intelligent perceptive touch control hardware system design under an instrument movement requirement.

Description

technical field [0001] The invention relates to a fully flexible transparent touch system. Background technique [0002] Touch devices play an increasingly important role in high-consumption frequency electronic products, covering mobile phones, tablets, notebooks, learning machines, vehicles and other fields, and the product update is very fast, and gradually develop into portable and wearable; With the development of artificial intelligence, instruments with intelligent perception, especially those with perception ability in the state of motion, are proposed for the adaptability of touch hardware, such as being attached to the moving component, and flexibility, such as bending with the moving component. challenge. Traditional touch components, especially touch hardware based on conductive glass, cannot meet the above requirements at all, and traditional conductive films such as indium tin oxide films prepared on flexible substrates cannot meet the stringent requirements o...
