Title:
CAMERA MODULE ACTUATOR MOVEMENT SENSING ELEMENT AND CAMERA MODULE FLEXIBLE CIRCUIT BOARD INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2018/212516
Kind Code:
A1
Abstract:
The present invention relates to a camera module actuator movement sensing element required for camera shake correction, and a camera module flexible circuit board including the same. On the camera module flexible circuit board, there are mounted: a plurality of actuator movement sensing elements for sensing each of the movement distances of an actuator in the x-axis and y-axis directions perpendicular to the optical-axis (z-axis) direction of the actuator to which a lens assembly is coupled, and transmitting the same by a method using a two-wire interface; and an OIS controller IC for performing camera shake correction by receiving, from the plurality of actuator movement sensing elements, a feedback of the movement distances of the actuator by the method using a two-wire interface, wherein: the plurality of actuator movement sensing elements share a common serial data pin and a common serial clock pin with each other, and the common serial data pine and the common serial clock pin are connected to a serial data pin and a serial clock pin of the OIS controller IC, respectively; and the plurality of actuator movement sensing elements share a common power pin and a common ground pin with each other, or share only a common power pin or a common ground pin with each other.
