    Abstract: A driving module is provided. The driving module includes a fixed portion, a movable portion movably connected to the fixed portion and used to hold an optical element having an optical axis, a driving assembly for driving the movable portion to move relative to the fixed portion, and a circuit assembly electrically connected to the driving assembly. The circuit assembly includes a first segment, a second segment, and a third segment. The first segment is resilient, plate-shaped, and movable relative to the fixed portion and the movable portion. The second segment is plate-shaped and affixed on the movable portion, wherein a thickness direction of the first segment is different from a thickness direction of the second segment. The third segment is plate-shaped and affixed on the fixed portion, wherein the second segment is movably connected to the third segment through the first segment.

    Abstract: A lens driving module is provided, configured to drive an optical element, including a holder, a circuit board assembly, a base module, and a magnetic element. The optical element is disposed in the holder, and the circuit board assembly has a driving coil. The base module has a metal substrate, an insulating layer, a circuit layer electrically connected with the driving coil, and a protective layer. The metal substrate has a bent portion where an opening is formed on. A wire of the circuit layer extends across the opening and forms a bridging portion. The protective layer has a protruding portion extending over the opening and covers the bridging portion. The magnetic element is coupled to the driving coil, and the two are configured to drive the optical element to move relative to the base module.

    Abstract: A driving mechanism is provided, including a fixed part, a movable part for holding an optical element, a driving assembly, and a circuit board. The driving assembly is used for driving the movable part to move relative to the fixed part. The circuit board is disposed on the fixed part, having a conductive portion exposed to an outer surface of the circuit board and a trace embedded in the circuit board. The conductive portion and the trace partially overlap when viewed in a horizontal direction perpendicular to the optical axis of the optical element.

    Abstract: An integrated structure of auto focus (AF) and optical image stabilizer (OIS) mechanisms includes a lens holder, a frame, magnets, suspension elements, and a driver board. The lens holder has an AF coil disposed outside thereof and is suspended in the frame. The inner edges of the sidewalls of the frame are close to but do not contact the outer edge of the AF coil. The magnets are disposed between the frame and the lens holder and correspond to the outer edge of the AF coil, for driving the lens holder back and forth along an optical axis (i.e. the Z axis). The suspension elements suspend the frame in the direction of the optical axis. The driving board has fine pattern coils each corresponding to one of the magnets, for driving the frame laterally (i.e. along the X-axis and/or Y-axis) with respect to the optical axis.

    Abstract: An optical system includes a base, a first lens driving module, and a second lens driving module. The first lens driving module includes a first lens holder, a first magnet, and a first coil. The first lens holder is configured to hold a first optical element. The first coil corresponding to the first magnet is configured to drive the first lens holder to move relative to the base. The second lens driving module includes a second lens holder, a second magnet, and a second coil. The second lens holder is configured to hold a second optical element. The second coil corresponding to the second magnet is configured to drive the second lens holder to move relative to the base. The first magnet is disposed between the first and second lens holders, and no other magnet is disposed between the first and second lens holders except the first magnet.
