Abstract

A first exemplary embodiment of the present disclosure includes a PCB (Printed Circuit Board) mounted with an image sensor, a holder member mounted on the PCB, a lens module directly mounted inside the holder member, an actuator arranged at an inside of the holder member, and an electronic circuit pattern formed on a surface of the holder member to conductibly connect the PCB and the actuator, where one end of the electronic circuit pattern is connected to the PCB, and the other end of the electronic circuit pattern is connected to the actuator.

First claim

What is claimed is:

1. A camera module, the camera module comprising:
a PCB (Printed Circuit Board) mounted with an image sensor;
an actuator holder mounted at an upper surface of the PCB and formed at an upper surface with a through hole;
a lens module directly mounted inside the actuator holder member; an actuator arranged inside the actuator holder; and
an electronic circuit pattern formed on a surface of the actuator holder to conductibly connect the PCB and the actuator, where one end of the electronic circuit pattern is connected to the PCB, and the other end of the electronic circuit pattern is connected to the actuator.

2. The camera module of claim 1 , wherein an upper surface of the actuator holder is formed to wrap the actuator, and the through hole is arranged at a position corresponding to a terminal unit of the actuator.

3. The camera module of claim 1 , wherein at least two through holes are provided.

4. The camera module of claim 1 , wherein the electronic circuit pattern is formed at a lateral surface and an upper surface of the actuator and at an inner circumferential surface of the through hole.

5. The camera module of claim 1 , wherein the actuator is connected to the electronic circuit pattern at a surface facing the through hole.

6. The camera module of claim 1 , wherein an outermost lens is arranged at an upper surface of the actuator.

7. The camera module of claim 6 , wherein a diameter of the outermost lens is formed smaller than that of the actuator or other lenses.

8. The camera module of claim 1 , wherein the actuator includes any one of a MEMS (Micro Electric Mechanical System) actuator moved by using an electrostatic force and a piezoelectric force, a liquid crystal lens, a piezoelectric polymer lens, a non-MEMS actuator, a silicon type actuator, and a liquid lens, or a combination of at least two such actuators.

9. The camera module of claim 6 , wherein the actuator includes any one of a MEMS (Micro Electric Mechanical System) actuator moved by using an electrostatic force and a piezoelectric force, a liquid crystal lens, a piezoelectric polymer lens, a non-MEMS actuator, a silicon type actuator, and a liquid lens, or a combination of at least two such actuators.

10. The camera module of claim 1 , wherein the actuator performs an auto focusing function or a handshake compensation function through changes in thickness or shape of a fixed lens or changes in refractive indexes of incident light.

11. The camera module of claim 6 , wherein the actuator performs an auto focusing function or a handshake compensation function through changes in thickness or shape of a fixed lens or changes in refractive indexes of incident light.

12. The camera module of claim 1 , wherein the electronic circuit pattern and the actuator are connected using a soldering, an Ag epoxy, a conductive epoxy or a wire bonding.

13. The camera module of claim 6 , wherein the electronic circuit pattern and the actuator are connected using a soldering, an Ag epoxy, a conductive epoxy or a wire bonding.
