Description

[0001] Cross-reference to related applications

[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2021-0156826, filed on November 15, 2021, with the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes. Technical Field

[0003] This disclosure relates to an optical image stabilization device and a camera module including the optical image stabilization device. Background Technology

[0004] With the development of communication technologies, mobile devices such as smartphones can be widely distributed, and therefore, there is a growing demand for the functionality of cameras included in mobile devices. For example, cameras included in mobile devices can be designed to provide advanced imaging features (e.g., autofocus, image stabilization, etc.) that are available in ordinary digital SLR (DSLR) cameras, despite their small size.

[0005] Optical image stabilization (OIS) prevents image blur when the camera shakes during exposure time, and is often necessary when imaging in low-light environments where the camera is shaky and the exposure time is relatively long. OIS can include digital IS (DIS), electronic IS (EIS), and optical IS (OIS). Among these, optical IS (OIS) fundamentally prevents image degradation caused by camera shake by correcting the optical path by moving a lens or image sensor in a direction orthogonal to the optical axis. Because mechanical actuators are required, implementing it as a device can be complex, and although the associated costs are high, excellent compensation performance can be achieved.

[0006] The lens barrel may include an optical system located therein, which may require a relatively large amount of force to drive the lens barrel. Image sensors can be relatively lightweight, allowing for advantageous implementation of excellent OIS functionality even with relatively small amounts of force. However, when the actuator used to drive the image sensor includes a permanent magnet, the magnetic field generated by the permanent magnet may affect adjacent electronic components. Furthermore, when a mobile device includes multiple cameras arranged adjacent to each other, the permanent magnets in each camera may negatively affect the operation of adjacent cameras, making it difficult to arrange the cameras adjacent to each other or to house the electronic components within the cameras.

[0007] The above information is presented as background information only to aid in understanding this disclosure. No determination or assertion is made as to whether any of the above content can be used as prior art with respect to this disclosure. Summary of the Invention

Detailed Implementation

[0038] In the following, although exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings, it should be noted that the examples are not limited thereto.

[0039] The following detailed embodiments are provided to aid the reader in gaining a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents to the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein, except for operations that must occur in a specific order, as will become apparent upon understanding this disclosure. Furthermore, for clarity and brevity, descriptions of features well-known in the art may be omitted.

[0040] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein are provided merely to illustrate some of the many possible ways in which the methods, apparatuses, and / or systems described herein will become apparent upon understanding this disclosure.

[0041] It should be noted that in this document, the term "may" is used in relation to examples or implementations, such as with respect to what an example or implementation may include or implement, meaning that there exists at least one example or implementation that includes or implements such features, and that all examples and implementations are not limited thereto.

[0042] Throughout this specification, when an element such as a layer, region, or substrate is described as being "on," "connected to," or "attached to" another element, the element may be directly "on," directly "connected to," or directly "attached to" the other element, or there may be one or more other elements between the element and the other element. Conversely, when an element is described as being "directly on," "directly connected to," or "directly attached to" another element, there are no other elements between the element and the other element.

[0043] As used herein, the term “and / or” includes any one of the associated listed items and any combination of any two or more items; similarly, “at least one” includes any one of the associated listed items and any combination of any two or more items.

[0044] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited by these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, first part, first region, first layer, or first section mentioned in these examples may also be referred to as a second component, second part, second region, second layer, or second section.

[0045] Spatial relative terms such as “above,” “above,” “below,” and “below” may be used herein for descriptive convenience to describe the relationship of one element relative to another, as shown in the accompanying drawings. In addition to covering the orientation depicted in the drawings, these spatial relative terms are intended to also cover different orientations of the device in use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “above” another element would be located “below” or “below” that other element. Thus, depending on the spatial orientation of the device, the term “above” covers both orientations of “above” and “below”. The device may also be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0046] The terminology used herein is for the purpose of describing various examples only and is not intended to limit this disclosure. Unless the context clearly indicates otherwise, the articles “a,” “an,” and “the” are intended to include the plural form as well. The terms “comprising,” “including,” and “having” indicate the presence of the stated features, numbers, operations, components, elements, and / or combinations thereof, but do not preclude the presence or addition of one or more other features, numbers, operations, components, elements, and / or combinations thereof.

[0047] Variations in the shapes shown in the figures may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the figures, but include shape variations that may occur during manufacturing.

[0048] In an exemplary embodiment, as shown in the figures, the X direction, Y direction, and Z direction can refer to directions parallel to the X-axis, Y-axis, and Z-axis, respectively. Furthermore, unless otherwise stated, the X direction can include both the +X-axis and -X-axis directions, which can also be applied to the Y and Z directions.

[0049] In exemplary embodiments, two directions (or axes) being parallel to each other may also include examples where the two directions (or axes) are substantially parallel to each other or substantially side by side. In exemplary embodiments, two directions being orthogonal to each other may also include examples where the two directions (or axes) are substantially perpendicular to each other or substantially at 90 degrees to each other. For example, a configuration in which the first axis and the second axis are orthogonal to each other may indicate that the first axis and the second axis can form an angle of 90 degrees or close to 90 degrees.

[0050] "Exemplary implementation" does not necessarily represent the same exemplary implementation. Specific features, structures, or characteristics may be combined in any suitable manner consistent with the exemplary implementation.

[0051] In an exemplary embodiment, “configured to” may indicate that a component may include structures necessary to achieve its function.

[0052] The features of the examples described herein can be combined in various ways that will become apparent upon gaining an understanding of this disclosure. Furthermore, although the examples described herein have multiple configurations, other configurations that will become apparent upon gaining an understanding of this disclosure are also possible.

[0053] One or more exemplary embodiments of this disclosure can enable a camera to provide effective optical image stabilization with low power, or to eliminate or reduce the influence of the magnetic field of the actuator used to drive the image sensor. For example, the influence of the magnetic field of the actuator used to drive the image sensor on electronic components disposed outside the camera can be reduced or eliminated.

[0054] 1. Camera module

[0055] Figure 1 This is a diagram illustrating the components included in camera module 1 according to an exemplary embodiment.

[0056] In an exemplary embodiment, camera module 1 may include lens module 20 and image sensor 11. Lens module 20 includes at least one lens 21 and a lens barrel 22 housing at least one lens 21. Light L can pass through lens module 20 and reach the imaging surface of image sensor 11. Camera module 1 may include AF driver 23, which can move lens module 20 in the optical axis direction to adjust focal length. AF driver 23 may include, for example, coils and magnets facing each other. The coils may be fixedly coupled to lens module 20, the magnets may be coupled to a fixed body such as a housing, and the electromagnetic interaction between the coils and the magnets can allow lens module 20 to move in the optical axis direction.

[0057] In an exemplary embodiment, camera module 1 may provide optical image stabilization (hereinafter referred to as "OIS") functionality. Camera module 1 may provide OIS functionality by driving image sensor 11. For example, camera module 1 may include OIS driver 12 configured to move image sensor 11 in a direction orthogonal to the optical axis, or rotate image sensor 11 about an axis parallel to the optical axis and / or about an axis orthogonal to the optical axis.

[0058] In an exemplary embodiment, camera module 1 may include sensor shifting module 10. Sensor shifting module 10 may include components necessary for implementing OIS functionality by driving image sensor 11. For example, sensor shifting module 10 may include image sensor 11 and OIS driver 12 for driving image sensor 11. As another example, sensor shifting module 10 may refer only to OIS driver 12 other than image sensor 11.

[0059] In an exemplary embodiment, in addition to the lens module 20 and the image sensor 11, the camera module 1 may also include optical elements. In an exemplary embodiment, the camera module 1 may include two or more lens modules. For example, the first optical element 30 and / or the second optical element 40 may be lens modules different from the lens module 20.

[0060] In an exemplary embodiment, the camera module 1 may include an optical path changing element disposed in front of the lens module 20. For example, the first optical element 30 may be implemented as a prism or a mirror. In another exemplary embodiment, the optical path changing element may be disposed between the image sensor 11 and the lens module 20. For example, the second optical element 40 may be implemented as a prism or a mirror.

[0061] In the following text, see references Figures 2A to 9B The described sensor shifting module 100 can be applied to Figure 1 Camera module 1 in the middle.

[0062] 2. Sensor displacement

[0063] 2.1. Translation of OIS

[0064] Figures 2A to 2C This is a diagram illustrating a sensor shifting module 100 according to an exemplary embodiment. The sensor shifting module 100 may include an OIS driver. The OIS driver may include at least one of a first OIS driver 120 and a second OIS driver 160, which will be described later. For example, Figure 1 The OIS driver 12 of the camera module 1 may include at least one of a first OIS driver 120 and a second OIS driver 160.

[0065] 2.1.1. Structure

[0066] The sensor shifting module 100 may include a first OIS driver 120 for driving the image sensor 111. In an exemplary embodiment, the first OIS driver 120 may include a second movable body 110 and a first movable body 130, the second movable body 110 including the image sensor 111. The second movable body 110 may be movably disposed within the first movable body 130. The second movable body 110 may be configured to move together with the image sensor 111. For example, the second movable body 110 may include a sensor substrate 112 on which the image sensor 111 is mounted and a sensor holder 113 coupled to the sensor substrate 112.

[0067] Reference Figures 2A to 2C The sensor holder 113 may include a plate 113a connected to the lower part of the sensor substrate 112 and an extension 113b extending upward (i.e., in the +Z direction) from the edge of the plate 113a. The extension 113b may be opposite to the drive coil 122, and the drive yoke 121 may be disposed on the extension 113b. In another exemplary embodiment, the drive yoke 121 may be mounted on the first movable body 130, and the drive coil 122 may be mounted on the sensor holder 113. In this case, the drive coil 122 and / or the yoke 123 may be disposed on the extension 113b.

[0068] The signal from the image sensor 111 can be transmitted to another electronic component (e.g., an image signal processor (ISP)) via the sensor substrate 112 and the connector.

[0069] The first movable body 130 may include a base 131 and components fixedly connected to the base 131. For example, the first movable body 130 may include a drive coil 122 and a yoke 123, which will be described in more detail later.

[0070] The second movable body 110 can be moved by the first OIS driver 120 in a direction orthogonal to the direction pointed to by the imaging surface 111a of the image sensor 111. In an exemplary embodiment, the first OIS driver 120 can compensate for shake of the camera module 1 or electronic device on which the image sensor 111 is mounted in a direction orthogonal to the optical axis O. The first OIS driver 120 can move (translate) the image sensor 111 in a first direction and a second direction orthogonal to the optical axis O. The first direction and the second direction can intersect each other. For example, the first OIS driver 120 can move the second movable body 110 in the X direction and / or Y direction orthogonal to the Z-axis, thereby correcting shake in the X direction and / or Y direction.

[0071] In an exemplary embodiment, the direction pointed to by the imaging surface 111a of the image sensor 111 can be referred to as the optical axis O direction. That is, the second movable body 110 can move relative to the first movable body 130 in a direction orthogonal to the optical axis O. In the figures, the optical axis O can be parallel to the Z-axis, and therefore, the Z-direction can refer to a direction parallel to the optical axis O. Furthermore, the X-direction or Y-direction can refer to a direction orthogonal to the optical axis O. For example, in an exemplary embodiment, the configuration of the second movable body 110 moving in the X-direction can indicate that the second movable body 110 can move in a direction orthogonal to the optical axis O. For another example, the configuration of the drive yoke 121 and the drive coil 122 opposite each other in the X-direction can indicate that the drive yoke 121 and the drive coil 122 are opposite each other in a direction orthogonal to the optical axis O. Furthermore, the X-direction or Y-direction can be an example of two directions orthogonal to the optical axis and intersecting each other, and in an exemplary embodiment, the X-direction and Y-direction can be configured as two directions orthogonal to the optical axis O and intersecting each other.

[0072] 2.1.2. Actuator

[0073] Reference Figures 2A to 2C In an exemplary embodiment, the first OIS driver 120 may include a drive coil 122 connected to one of the second movable body 110 and the first movable body 130, and a drive yoke 121 connected to the other of the second movable body 110 and the first movable body 130. For example, refer to Figure 2A In an exemplary embodiment, the drive coil 122 and the drive yoke 121 can be connected to the base 131 and the sensor bracket 113, respectively. The drive yoke 121 and the drive coil 122 can be opposite each other in a direction orthogonal to the optical axis O. The electromagnetic interaction between the drive yoke 121 and the drive coil 122 allows the second movable body 110 to move relative to the first movable body 130 in a direction orthogonal to the optical axis O.

[0074] In an exemplary embodiment, the first OIS driver 120 may further include a yoke 123 disposed on one side of the coil. The yoke 123 allows the magnetic field generated in the coil to be concentrated in the direction toward the driving yoke 121. Since the yoke 123 is disposed on one side of the driving coil 122, the magnetic field generated by the driving coil 122 can be prevented from affecting other electronic components, or the influence of the magnetic field on these other electronic components can be reduced.

[0075] In one exemplary embodiment, the drive coil 122 and the drive yoke 121 can be connected to the first movable body 130 and the second movable body 110, respectively. However, in another exemplary embodiment, the drive coil 122 and the drive yoke 121 can be connected to the second movable body 110 and the first movable body 130, respectively. For example, the drive coil 122 and the drive yoke 121 can be connected to the sensor bracket 113 and the base 131, respectively.

[0076] An air gap may be formed between the drive coil 122 and the drive yoke 121. Alternatively, the space between the drive coil 122 and the drive yoke 121 may be an air gap. That is, there may be no other components (e.g., a magnet, i.e., a permanent magnet) between the drive coil 122 and the drive yoke 121. The drive coil 122 and the drive yoke 121 may be directly opposite each other with an air gap between them.

[0077] Figures 2A to 2C The components of the first OIS driver 120 are shown, and its exemplary embodiments are not limited to those shown. Figures 2A to 2C The structure is as follows. The first OIS driver 120 may include a voice coil motor (VCM) actuator. For example, the drive yoke 121, which is partially included in the first OIS driver 120, may be replaced by a magnet. The magnet may be positioned opposite the drive coil 122 instead of the drive yoke 121, and the electromagnetic interaction between the magnet and the drive coil 122 may allow the second movable body 110 to move relative to the first movable body 130.

[0078] 2.1.3. PCB Springs

[0079] In an exemplary embodiment, the sensor shifting module 100 may include a substrate 140 that mechanically connects a second movable body 110 to a first movable body 130. The substrate 140 can connect the second movable body 110 to the first movable body 130 such that the second movable body 110 can move relative to the first movable body 130 in a direction orthogonal to the optical axis. A portion of the substrate 140 may deform according to the movement of the second movable body 110 relative to the first movable body 130. That is, a portion of the substrate 140 may be flexible. When the substrate 140 deforms, a restoring force can be generated within the substrate 140, and this restoring force can allow the second movable body 110 to return to its initial position. When current is applied to the drive coil 122, the second movable body 110, in an equilibrium state, can move relative to the first movable body 130, and when current no longer flows in the drive coil 122, the second movable body 110 can return to its initial position via the substrate 140.

[0080] Figure 3This is a diagram showing, from above, a substrate 140 on which an image sensor 111 is mounted, according to an exemplary embodiment. (Refer to...) Figures 2A to 2C and Figure 3 The substrate 140 may include a movable portion 141 (floating portion) on which the sensor substrate 112 is mounted, and a fixed portion 142 fixed to the first movable body 130 (fixed portion). The sensor substrate 112 and the movable portion 141 may be electrically connected to each other via solder balls at corresponding contact points P1 and P2.

[0081] When the second movable body 110 (or image sensor 111) moves relative to the first movable body 130, the movable portion 141 can move relative to the fixed portion 142. The substrate 140 may include a support portion 143 connecting the movable portion 141 to the fixed portion 142. At least a portion of the support portion 143 can deform according to the relative movement between the movable portion 141 and the first movable body 130. For example, the support portion 143 may be configured as a flexible substrate. The flexible substrate may be provided in the form of a conductive pattern (or trace 145) formed in a film formed of a polyimide material.

[0082] In an exemplary embodiment, substrate 140 may include a plurality of bridging elements 144 connecting movable portion 141 and fixed portion 142. The plurality of bridging elements 144 may be included in at least a portion of support portion 143. The plurality of bridging elements 144 may be formed of a flexible material such that support portion 143 may deform when movable portion 141 moves relative to fixed portion 142. When second movable body 110 moves relative to first movable body 130, movable portion 141 may move relative to fixed portion 142, and bridging elements 144 may deform. The restoring force generated when bridging elements 144 deform may allow second movable body 110 or movable portion 141 to return to its initial position. Each of the plurality of bridging elements 144 may include at least one wire 145 (electrical trace 145). That is, the plurality of bridging elements 144 may mechanically and electrically connect movable portion 141 (or second movable body 110) and fixed portion 142 (or first movable body 130). In other words, the bridging element 144 can support the image sensor 111 and can be used as a path for transmitting signals from the image sensor 111.

[0083] In an exemplary embodiment, substrate 140 may include a guide 146 disposed between movable portion 141 and fixed portion 142. For example, guide 146 may be configured as a frame surrounding movable portion 141. Fixed portion 142, guide 146, and movable portion 141 may be connected to each other via bridging element 144. For example, substrate 140 may include a first bridging element 147 extending from guide 146 to fixed portion 142 and a second bridging element 148 extending from movable portion 141 to guide 146. First bridging element 147 and second bridging element 148 may extend in a direction orthogonal to the optical axis. First bridging element 147 and second bridging element 148 may extend in a direction in which first bridging element 147 and second bridging element 148 intersect each other. For example, first bridging element 147 may extend in the Y direction, and second bridging element 148 may extend in the X direction.

[0084] Each of the first bridging element 147 and the second bridging element 148 may include one or more bridging elements 144. Figure 3 In the first bridging member 147, four bridging elements 144 extending in the Y direction may be included, and the second bridging member 148 may include four bridging elements 144 extending in the X direction. Figure 3 The substrate 140 can be an example, and the shape of the support portion 143 that connects the movable portion 141 to the fixed portion 142 can be varied. For example, the support portion 143 may include a plurality of bridging elements 144 extending directly from the movable portion 141 to the fixed portion 142. As another example, the first bridging member 147 or the second bridging member 148 may include five bridging elements 144. The number of bridging elements 144 included in the first bridging member 147 or the second bridging member 148 may correspond to the number of terminals of the image sensor 111.

[0085] The substrate 140 may include wires 145 for transmitting signals from the image sensor 111. A plurality of bridging elements 144 included in the support portion 143 may embed the wires 145 therein. The image sensor 111 may be mounted on a sensor substrate 112, and the sensor substrate 112 may be electrically connected to a fixed portion 142 of the substrate 140. The wires 145 may extend from each contact point P2 formed in the movable portion 141. The wires 145 may extend to the fixed portion 142 via the bridging elements 144. The wires 145 extending to the fixed portion 142 may be electrically connected to another substrate or electronic component.

[0086] Figure 3 A wire 145 formed on a substrate 140 is shown, and for ease of description, only a portion of the wire 145 extending from the contact point P2 is shown.

[0087] 2.1.4. Position Sensor

[0088] Reference Figures 2A to 2C In an exemplary embodiment, the first OIS driver 120 may include a position sensor 127 that can measure how much the second movable body 110 has moved in a direction orthogonal to the optical axis O. The position sensor 127 may be configured as a Hall sensor or a magnetoresistive sensor.

[0089] The first OIS driver 120 may include a sensing magnet 124 that moves with the second movable body 110 and is opposite to the position sensor 127. The position sensor 127 may be configured to be opposite the sensing magnet 124. For example, the position sensor 127 may be disposed on a base 131, and the sensing magnet 124 may be disposed on a substrate 140 to be opposite the position sensor 127 in the optical axis direction (in the Z direction). As another example, the position sensor 127 may be disposed on the substrate 140, and the sensing magnet 124 may be disposed on the base 131. Two or more of each of the position sensor 127 and the sensing magnet 124 may be disposed in pairs.

[0090] 2.1.5. Translational Arrangement

[0091] Figure 4 This is a diagram showing the first OIS driver 120 according to an exemplary embodiment, viewed from above.

[0092] The first OIS driver 120 may include a plurality of unit drivers 120a, 120b, 120c, and 120d. Each of the unit drivers 120a, 120b, 120c, and 120d may include a driving yoke 121 and a driving coil 122 opposite to each other. Each of the unit drivers 120a, 120b, 120c, and 120d may also include a yoke 123 disposed on one side of the driving coil 122. For example, the first unit driver 120a may include a first driving yoke 121a, a first driving coil 122a, and a first yoke 123a.

[0093] Since only an attractive force can be generated between the drive coil 122 and the drive yoke 121, at least two unit drivers may be required to move the second movable body 110 back and forth in one direction.

[0094] Reference Figure 4The first OIS driver 120 may include a first unit driver 120a disposed in the -X direction of the second movable body 110, and a second unit driver 120b disposed in the +X direction of the second movable body 110, to compensate for jitter in the X direction. The first unit driver 120a may include a first drive yoke 121a connected to the second movable body 110 and a first drive coil 122a connected to the base 131. The first unit driver 120a may also include a first yoke 123a disposed on one side of the first drive coil 122a. The second unit driver 120b may include a second drive yoke 121b connected to the second movable body 110 and a second drive coil 122b connected to the base 131. The second unit driver 120b may also include a second yoke 123b disposed on one side of the second drive coil 122b.

[0095] Reference Figure 4 The first OIS driver 120 may include a third unit driver 120c disposed in the +Y direction of the second movable body 110 and a fourth unit driver 120d disposed in the -Y direction of the second movable body 110 to compensate for jitter in the Y direction. The third unit driver 120c may include a third drive yoke 121c connected to the second movable body 110 and a third drive coil 122c connected to the base 131. The third unit driver 120c may also include a third yoke 123c disposed on one side of the third drive coil 122c. The fourth unit driver 120d may include a fourth drive yoke 121d connected to the second movable body 110 and a fourth drive coil 122d connected to the base 131. The fourth unit driver 120d may also include a fourth yoke 123d disposed on one side of the fourth drive coil 122d.

[0096] 2.1.6. Translation

[0097] Figures 5A to 5D It is shown that due to Figure 4 The diagram shows the movement of a movable body caused by the OIS driver in the diagram.

[0098] Reference Figure 5A Current can be applied to the first drive coil 122a, causing the first drive coil 122a to pull the first drive yoke 121a in the direction of the arrow, and thus, the second movable body 110 can move in the -X direction. (Refer to...) Figure 5B Current can be applied to the second drive coil 122b, causing the second drive coil 122b to pull the second drive yoke 121b in the direction of the arrow, and thus, the second movable body 110 can move in the +X direction. (Refer to...) Figure 5CCurrent can be applied to the third drive coil 122c, causing the third drive coil 122c to pull the third drive yoke 121c in the direction of the arrow, and thus, the second movable body 110 can move in the +Y direction. (Refer to...) Figure 5D Current can be applied to the fourth drive coil 122d, so that the fourth drive coil 122d can pull the fourth drive yoke 121d in the direction of the arrow, and thus the second movable body 110 can move in the -Y direction.

[0099] 2.2. Tilt OIS

[0100] 2.2.1. Inclined Structure

[0101] Figure 2D The bottom surface of the fixed body 170 and the lower surface of the first movable body 130 in an exemplary embodiment are shown. (Refer to...) Figures 2A to 2D The sensor shifting module 100 may include a second OIS driver 160. The sensor shifting module 100 may include a second OIS driver 160 for moving a first movable body 130 relative to a fixed body 170. The second OIS driver 160 may rotate the first movable body 130 relative to the fixed body 170 based on an axis orthogonal to the optical axis O. Shake correction can be achieved by translating the image sensor 111 in a direction orthogonal to the optical axis O; however, due to the relatively small size of the moving camera, the translation range may also be relatively small, and therefore, when the degree of shake is large, the correction amount may not be sufficient to reach the level of shake. The second OIS driver 160 can correct shake by tilting the image sensor 111, and can provide excellent quality shake correction even for relatively large degrees of shake.

[0102] Meanwhile, in an exemplary embodiment, the sensor shifting module 100 may include a first OIS driver 120 and a second OIS driver 160, but its exemplary embodiment is not limited thereto, and the sensor shifting module 100 may include only one of the first OIS driver 120 and the second OIS driver 160.

[0103] The first movable body 130 can be movably disposed within the fixed body 170. The first movable body 130 can be moved relative to the fixed body 170 by the second OIS driver 160. An image sensor 111 can be coupled to the first movable body 130. The image sensor 111 can be movably coupled to the first movable body 130. For example, the image sensor 111 can be coupled to a second movable body 110, and the second movable body 110 can be movably coupled to the first movable body 130.

[0104] 2.2.2. Tilting Actuator

[0105] The second OIS driver 160 may include at least one tilt actuator disposed between the fixed body 170 and the first movable body 130. The tilt actuator may include a first drive element 161 disposed on the fixed body 170 and a second drive element 162 disposed on the first movable body 130. The first movable body 130 may rotate relative to the fixed body 170 through electromagnetic interaction between the first drive element 161 and the second drive element 162. In an exemplary embodiment, one of the first drive element 161 and the second drive element 162 may be a coil, and the other may be a coil, a magnet, or a yoke. When no magnet is present in the first drive element 161 and the second drive element 162, the magnetic field formed by the second OIS driver 160 may not exist unless current is applied to the second OIS driver 160, thereby reducing the influence of the second OIS driver 160 on surrounding electronic components.

[0106] For example, refer to Figure 2A In an exemplary embodiment, the first driving element 161 may be a coil, and the second driving element 162 may be a magnetic yoke. When current flows through the coil, magnetic resistance can be generated between the coil and the magnetic yoke, which can tilt the first movable body 130.

[0107] For another example, see Figure 2B In an exemplary embodiment, the first driving element 161 may be a coil, and the second driving element 162 may be a magnet. When current flows through the coil, an attractive or repulsive force may be generated between the coil and the magnet, which may tilt the first movable body 130.

[0108] As another example, see Figure 2C In an exemplary embodiment, both the first driving element 161 and the second driving element 162 can be coils. When current flows through the two coils, the two coils can become electromagnets, and magnetic attraction or repulsion can be generated between the two coils.

[0109] In an exemplary embodiment, the tilt actuator may further include a yoke 163. The yoke 163 may be disposed on one side of the first drive element 161 and / or the second drive element 162. The yoke 163 can concentrate the magnetic field generated by the coil or magnet to the opposite side. Furthermore, the yoke 163 can prevent the magnetic field generated by the coil or magnet from affecting other electronic components, or can reduce the influence of the magnetic field on other electronic components. For example, see reference... Figure 2A The first driving element 161 can be a coil, and a yoke 163 can be disposed below the coil. The yoke 163 allows the magnetic field generated when current flows in the coil to flow in the +Z direction (or toward the second driving element 162). For another example, see [reference needed]. Figure 2BThe first driving element 161 can be a coil, and the second driving element 162 can be a magnet, and the yoke 163 can be positioned below the first driving element 161 and above the second driving element 162. As another example, see [reference needed]. Figure 2C Both the first driving element 161 and the second driving element 162 can be coils, and the magnetic yoke 163 can be disposed on the outside of each of the two driving elements 161 and 162.

[0110] 2.2.3. Tilted guiding ball

[0111] In an exemplary embodiment, the second OIS driver 160 may include a tilting guide ball 164 disposed between the fixed body 170 and the first movable body 130. The tilting guide ball 164 may provide a tilt center of the first movable body 130 relative to the fixed body 170. For example, the first movable body 130 may be tilted about the tilting guide ball 164. The lower surface of the first movable body 130 and the bottom surface of the fixed body 170 may be opposite each other in the optical axis O direction, and a groove for partially receiving the tilting guide ball 164 may be formed in each of the lower surface of the first movable body 130 and the bottom surface of the fixed body 170.

[0112] 2.2.4. Tilt and pull

[0113] In an exemplary embodiment, the second OIS driver 160 may include a first magnetic member 165 disposed on the fixed body 170 and a second magnetic member 166 disposed on the first movable body 130, with the first magnetic member 165 and the second magnetic member 166 facing each other in a direction parallel to the optical axis O. A magnetic attraction force can be generated between the first magnetic member 165 and the second magnetic member 166, which can pull the first movable body 130 to the bottom surface of the fixed body 170. Therefore, the tilting guide ball 164 can remain in contact with the first movable body 130 and the fixed body 170, allowing the first movable body 130 to tilt smoothly relative to the fixed body 170.

[0114] One of the first magnetic component 165 and the second magnetic component 166 can be a magnet, and the other can be a magnet or a yoke. For example, refer to Figure 2A The first magnetic component 165 can be a magnetic yoke, and the second magnetic component 166 can be a magnet.

[0115] 2.2.5. Tilt Sensor

[0116] In an exemplary embodiment, the second OIS driver 160 may include a position sensor 167 configured to measure the tilt of the first movable body 130. The position sensor 167 may be implemented as a Hall sensor or a magnetoresistive sensor, and in this case, the second OIS driver 160 may include a sensing magnet opposite the position sensor 167. In an exemplary embodiment, one of the first magnetic member 165 and the second magnetic member 166 may be a magnet, and the other may be a yoke, and the magnetic member serving as the magnet may be used as the sensing magnet. For example, refer to... Figure 2A The second magnetic component 166 can be a magnet, the first magnetic component 165 can be a magnetic yoke, the first magnetic component 165 can include a through portion 165a, and the position sensor 167 can be disposed in the through portion 165a.

[0117] 2.2.6. Leaf Spring

[0118] In an exemplary embodiment, the second OIS actuator 160 may include an elastic member 168 that provides a restoring force to the first movable body 130 when the first movable body 130 is tilted. The elastic member 168 can deform according to the tilt of the first movable body 130, provide a restoring force to the first movable body 130, and allow the first movable body 130 to return to its initial position. (See also...) Figure 2A The elastic member 168 may be disposed between the first movable body 130 and the fixed body 170. In an exemplary embodiment, the elastic member 168 may be configured as a leaf spring, which bends toward either the first movable body 130 or the fixed body 170. For example, see reference... Figure 2A The elastic member 168 may have a curved shape that bends in the direction of the first movable body 130, and both ends of the elastic member 168 may be fixed to the bottom surface of the fixed body 170.

[0119] 2.2.7. Arrangement

[0120] The second OIS driver 160 may include multiple tilt actuators (e.g., 160-1, 160-2, 160-3, 160-4). See reference. Figure 2DFour tilt actuators 160-1, 160-2, 160-3, and 160-4 may be disposed between the fixed body 170 and the first movable body 130. Each of the four tilt actuators 160-1, 160-2, 160-3, and 160-4 may include a first drive element 161 and a second drive element 162 opposite to each other. Each of the plurality of tilt actuators 160-1, 160-2, 160-3, and 160-4 may generate an attractive or repulsive force, and the direction and amount of rotation of the first movable body 130 may be determined by the sum of the torques provided to the first movable body 130 by each of the plurality of tilt actuators 160-1, 160-2, 160-3, and 160-4.

[0121] In an exemplary embodiment, one or more sets of first magnetic members 165 and second magnetic members 166 may be disposed at positions spaced apart from the tilted guide ball 164. (Refer to...) Figure 2D The first magnetic component 165 and the second magnetic component 166 can be positioned in four locations around the tilted guide ball 164. However, Figure 2D The arrangement of the first magnetic component 165 and the second magnetic component 166 shown may be merely an example.

[0122] 2.2.8. Tilting motion

[0123] Figure 6 and Figure 7 The tilt of the first movable body 130 is shown.

[0124] Reference Figure 6 and Figure 7 The first actuator may include a first tilt actuator 160a disposed on one side relative to the tilt center (or tilt guide ball 164) and a second tilt actuator 160b disposed on the other side. Each of the first tilt actuator 160a and the second tilt actuator 160b may include at least one coil, and when current flows through the coil, it may provide a torque in the Y direction to the first movable body 130.

[0125] Reference Figure 6 By controlling the current flowing in the coil, an attractive force can be generated between the first drive element 161 and the second drive element 162 included in the first tilt actuator 160a, and a repulsive force can be generated between the first drive element 161 and the second drive element 162 included in the second tilt actuator 160b, so that the first movable body 130 can rotate in a counterclockwise direction. When the first movable body 130 tilts in a counterclockwise direction, the elastic member 168 adjacent to the first tilt actuator 160a can deform, so that a clockwise torque can be provided to the first movable body 130.

[0126] Reference Figure 7 By controlling the current flowing in the coil, a repulsive force can be generated between the first drive element 161 and the second drive element 162 included in the first tilt actuator 160a, and an attractive force can be generated between the first drive element 161 and the second drive element 162 included in the second tilt actuator 160b, so that the first movable body 130 can rotate in a clockwise direction. When the first movable body 130 tilts in a clockwise direction, the elastic member 168 adjacent to the second tilt actuator 160b can deform, so that a torque in a counterclockwise direction can be provided to the first movable body 130.

[0127] When the first drive element 161 and the second drive element 162 included in the first tilt actuator 160a or the second tilt actuator 160b are coils and yokes, only an attractive force can be generated between the first drive element 161 and the second drive element 162, and no repulsive force can be generated. In this case, only the attractive force generated between the first drive element 161 and the second drive element 162 can tilt the first movable body 130.

[0128] Figure 6 and Figure 7 An example of tilting the first movable body 130 is shown, illustrating the rotation of the first movable body 130 about the Y-axis. The first actuator may include three or more tilt actuators, and through their combination, the first movable body 130 can rotate about several axes orthogonal to the optical axis O.

[0129] 2.3. Magnetic Reluctance

[0130] 2.3.1. Translation Driver

[0131] In an exemplary embodiment, the first OIS driver 120 may not include a permanent magnet. In an exemplary embodiment, when no current flows in the drive coil 122, the magnetic field generated by the drive yoke 121 may be zero or may have a relatively small level. Therefore, the magnetic field generated by the first OIS driver 120 can be prevented from affecting other electronic components (e.g., other electronic components in camera module 1, or electronic components in other camera modules 1), or the influence of the magnetic field on other electronic components can be reduced.

[0132] In an exemplary embodiment, the magnetic yoke (e.g., a component referred to as the magnetic yoke in the exemplary embodiment, such as...) Figure 2A The driving yoke 121 and yoke 123 in the design can be formed of a soft magnetic material. The soft magnetic material can have low coercivity and can be magnetized when exposed to a magnetic field, but when the magnetic field is removed, the soft magnetic material can lose its magnetism or can have a relatively low level of magnetism.

[0133] When current is applied to the drive coil 122, the drive yoke 121 can be magnetized, thereby generating magnetic resistance between the drive coil 122 and the drive yoke 121. An attractive force can be generated in the direction opposite to each other between the drive yoke 121 and the drive coil 122, allowing the second movable body 110 to move relative to the first movable body 130 in a corresponding direction. For example, refer to... Figure 4 When current is applied to the first drive coil 122a, an attractive force is generated between the first drive coil 122a and the first drive yoke 121a, allowing the second movable body 110 to move in the -X direction. Conversely, when current is applied to the second drive coil 122b, an attractive force is generated between the second drive coil 122b and the second drive yoke 121b, allowing the second movable body 110 to move in the +X direction.

[0134] 2.3.2. Tilting Driver

[0135] In an exemplary embodiment, the second OIS driver 160 may not include a permanent magnet. For example, one of the first driving element 161 and the second driving element 162 may be a coil, and the other may be a coil or a yoke. When both the first driving element 161 and the second driving element 162 are coils, an attractive or repulsive force can be generated between the first driving element 161 and the second driving element 162 depending on the direction of the current flowing through the two coils. When the first driving element 161 is a coil and the second driving element 162 is a yoke, and current flows in the coil, magnetic resistance can be generated between the yoke and the coil.

[0136] In an exemplary embodiment, when no current flows in the second OIS driver 160 (or the coil included in the second OIS driver 160), the magnetic field generated by the second OIS driver 160 can be zero or can have a very small level. Therefore, the magnetic field generated by the second OIS driver 160 can be prevented from affecting other electronic components (e.g., other electronic components in camera module 1, or electronic components in other camera modules 1), or the influence of the magnetic field on other electronic components can be reduced.

[0137] 2.4. Deformation of flexible substrate

[0138] Figures 8A to 8D This is a diagram showing the deformation of the substrate 140 according to the movement of the second movable body 110.

[0139] Reference Figure 8AWhen the second movable body 110 moves in the -X direction, the movable portion 141 of the substrate 140 can also move in the -X direction, and therefore, the first bridging member 147 connecting the guide 146 to the fixed portion 142 can deform. Since the bridging element 144 included in the first bridging member 147 is elastic, the first bridging member 147 can provide a restoring force to return the movable portion 141 in the direction opposite to the direction of movement (+X direction). Therefore, when no current is applied to the first OIS driver 120, the movable portion 141 can move in the +X direction.

[0140] Reference Figure 8B When the second movable body 110 moves in the +X direction, the movable portion 141 of the substrate 140 can also move in the +X direction, and therefore, the first bridging member 147 connecting the guide 146 to the fixed portion 142 can deform. Since the bridging element 144 included in the first bridging member 147 is elastic, the deformed first bridging member 147 can provide a restoring force to return the movable portion 141 in the opposite direction to the direction of movement (-X direction).

[0141] Reference Figure 8C When the second movable body 110 moves in the +Y direction, the movable portion 141 of the substrate 140 can also move in the +Y direction, and therefore, the second bridging member 148 connecting the movable portion 141 to the guide 146 can deform. Since the bridging element 144 included in the second bridging member 148 is elastic, the deformed second bridging member 148 can provide a restoring force to cause the movable portion 141 to return in the opposite direction to the direction of movement (-Y direction).

[0142] Reference Figure 8D When the second movable body 110 moves in the -Y direction, the movable portion 141 of the substrate 140 can also move in the -Y direction, and therefore, the second bridging member 148 connecting the movable portion 141 to the guide 146 can deform. Since the bridging element 144 included in the second bridging member 148 is elastic, the deformed second bridging member 148 can provide a restoring force to cause the movable portion 141 to return in the direction opposite to the direction of movement (+Y direction).

[0143] 2.5. Deformation of the Mobility Unit

[0144] Figure 9A and Figure 9B It shows having with Figure 2A The figures show different forms of sensor brackets 213 and 313.

[0145] Reference Figure 9AThe sensor holder 213 can be disposed on the sensor substrate 112. In an exemplary embodiment, the sensor holder 213 may include a plate 213a disposed on the sensor substrate 112 and an extension portion 213b extending downward (in the -Z direction) from the edge of the plate 213a. The extension portion 213b may be connected to the drive coil of the first OIS driver 120 (e.g., Figure 2A The drive coil 122 in the first OIS driver 120 is opposite to the drive yoke (e.g., the drive yoke of the first OIS driver 120) Figure 2A The drive yoke 121 in the sensor holder 213 can be mounted on the extension 213b. In another exemplary embodiment, the drive yoke can be mounted on the first movable body 130, and the drive coil can be mounted on the sensor holder 213. In this case, the drive coil and / or the yoke (e.g., Figure 2A The magnetic yoke 123 can be mounted on the extension 213b. Figure 2A Compared to sensor bracket 113 in the middle, Figure 9A The sensor bracket 213 may be more advantageous in avoiding interference with the solder balls that connect the sensor substrate 112 to the substrate 140. Furthermore, when the sensor bracket 213 is positioned above the sensor substrate 112, its thickness can be increased relatively freely, which can improve the mechanical rigidity of the sensor bracket 213.

[0146] Reference Figure 9A The image sensor 111 can be connected to the sensor substrate 112 through conductive paths at corresponding contact points P3 and P4.

[0147] Reference Figure 9B The sensor holder 313 can be disposed on the sensor substrate 112. In an exemplary embodiment, the sensor holder 313 may include a plate 313a disposed on the sensor substrate 112 and an extension portion 313b extending downward (in the -Z direction) from the edge of the plate 313a. The extension portion 313b may be connected to the drive coil of the first OIS driver 120 (e.g., Figure 2A The drive coil 122 in the first OIS driver 120 is opposite to the drive yoke (e.g., the drive yoke of the first OIS driver 120) Figure 2A The drive yoke 121 in the sensor holder 313 can be mounted on the extension 313b. In another exemplary embodiment, the drive yoke can be mounted on the first movable body 130, and the drive coil can be mounted on the sensor holder 313. In this case, the drive coil and / or the yoke (e.g., Figure 2A The magnetic yoke 123 can be mounted on the extension 313b. Figure 2A Compared to sensor bracket 113 in the middle, Figure 9BThe sensor bracket 313 is more advantageous in avoiding interference with the solder balls connecting the sensor substrate 112 and the substrate 140. Furthermore, when the sensor bracket 313 is positioned on the upper side of the sensor substrate 112, the thickness of the sensor bracket 313 can be increased relatively freely, which can improve the mechanical rigidity of the sensor bracket 313.

[0148] Reference Figure 9B The image sensor 111 can be directly mounted on the sensor substrate 112.
