BUTTON STRUCTURE HAVING FORCE TOUCH FUNCTION
Document Type and Number:
WIPO Patent Application WO/2020/004787
Kind Code:
A1
Abstract:
A button structure comprising a force touch module, according to the present invention, comprises: a housing having a floor surface and a button hole and providing an internal space therebetween; a fingerprint recognition module inserted in the button hole so as to be exposed on the outside of the housing; the force touch module disposed in the internal space of the housing so as to sense a force touch event applied to the fingerprint recognition module; and a pusher attached to the fingerprint recognition module so as to transfer, to the force touch module, pressure generated by the force touch event of the fingerprint recognition module. The present invention can minimize internal space by not requiring space for a separate structure for a dome switch and can have a semi-permanent lifespan unlike a dome switch structure since an electrical signal is used.
