POWER SUPPLY TO MOVABLE APERTURE UNIT
Document Type and Number:
WIPO Patent Application WO/2022/126570
Kind Code:
A1
Abstract:
Embodiments of this application provide a technique used to supply power to an aperture unit that moves with a lens unit in a camera module, wherein there is no need of a flexible printed circuit to couple the aperture unit with an outside power source or an external coil to allow the aperture unit to function. Embodiments of the present application supply power to an aperture unit that moves with a lens unit via one or more springs that movably support a holder onto which the aperture unit and the lens unit are mounted.
