Title:
DISPLACEMENT SENSOR AND CAMERA MODULE HAVING THE SAME
Document Type and Number:
WIPO Patent Application WO/2017/179803
Kind Code:
A1
Abstract:
A displacement sensor comprises a first frame; a second frame; a first coil wherein a first voltage formed at the first frame is applied; a second coil formed at the first frame, wherein a current of a second voltage flows if the first voltage is applied to the first coil; a conductor coupled to the second frame; and a detector for calculating a relative position between the first frame and the second frame by monitoring the second voltage. Since two coils are embodied in one frame, the number of process times can be reduced and space utility can be enhanced.
