Abstract: An imaging lens driving module includes a lens carrier, a molded receiving base, a rolling element, a molded frame element and a driving mechanism. The lens carrier defines an optical axis. The molded receiving base is configured to receive the lens carrier. The rolling element is disposed between the lens carrier and the molded receiving base, and the lens carrier is allowed to be displaceable along the optical axis and relatively to the molded receiving base. The molded frame element is coupled with the molded receiving base for defining an inner space to receive the lens carrier. The driving mechanism drives the lens carrier displaceable along the optical axis, and includes a driving magnet and a driving coil, wherein the driving magnet is disposed on the lens carrier, the driving coil is corresponding to and faces towards the driving magnet.

Abstract: A lens driving apparatus includes an imaging lens assembly, a driving mechanism and a carrier element. The imaging lens assembly includes at least one plastic lens element. The plastic element includes an effective optical portion, a peripheral portion and a light-shielding layer. The peripheral portion surrounds the effective optical portion. The light-shielding layer is disposed on an object side of the peripheral and surrounds the effective optical portion. The driving mechanism includes at least one coil and at least one magnet. The magnet is disposed correspondingly with the coil. Both of the plastic element and the one of the coil and the magnet are directly connected with the carrier element. An outer surface of the carrier element includes an assembling structure. The assembling structure is directly contacted with one of the coil and the magnet. The assembling structure and the carrier element are made integrally.

Abstract: An imaging lens driving module includes an imaging lens set, a carrier element and a driving mechanism. The imaging lens set has an optical axis. The carrier element is configured to dispose the imaging lens set, and includes an assembling structure. The assembling structure is disposed on an outer surface of the carrier element, and extends along a direction away from the optical axis. The driving mechanism is configured to drive the carrier element to move, and includes at least one coil pair and at least two magnets. The coil pair is disposed on the assembling structure, and includes a bottom layer coil and a top layer coil. The bottom layer coil is wound around and directly contacted with the assembling structure. The top layer coil is stacked on and wound around the bottom layer coil. The magnets correspond to the coil pair, respectively.

Abstract: Provided is a lens assembly driving module including a photographing lens assembly, a first driving mechanism and a second driving mechanism. The photographing lens assembly includes N lens elements and has an optical axis passing through the N lens elements. The first driving mechanism drives at least N/2 said lens elements to move along the optical axis of the photographing lens assembly. The second driving mechanism enables a relative distance along the optical axis of two adjacent ones of the N lens elements to vary. Therefore, any specific one of the lens elements is capable of being driven to optimize optical imaging resolution of various fields of view independently within a real shot at different object distances.
