Camera module with optical image stabilization actuator

An optical image stabilization actuator, comprising:

• a movable part comprising an image sensor having an imaging surface, and configured to move in a direction parallel to the imaging surface;
• a fixed part spaced apart from the movable part in a direction perpendicular to the imaging surface;
• a plurality of supports each connected to one of the fixed part and the movable part;
• and
• a plurality of bridges configured to support a movement of the movable part, and configured to connect the plurality of supports to each other.

A camera module, comprising:

• a sensor substrate on which an image sensor is disposed;
• a fixed frame;
• and
• a movable frame, disposed on the fixed frame;
• wherein the sensor substrate comprises:
• a fixed printed circuit board (PCB), coupled to a lower surface of the fixed frame;
• a movable PCB, on which the image sensor is mounted, and configured to move together with the movable frame in a direction perpendicular to an optical axis direction;
• and
• a connection part configured to connect the fixed PCB and the movable PCB to each other;
• wherein the movable PCB is configured to overlap the fixed PCB in the optical axis direction.
