BACKGROUND

Field

The disclosure relates to an electronic device, for example, an electronic device including a camera module.

Description of Related Art

The growth of electronics, information, and communication technologies leads to integration of various functions into a single electronic device. For example, smartphones pack the functionalities of a sound player, imaging device, and scheduler, as well as the communication functionality and, on top of that, may implement more various functions by having applications installed thereon. An electronic device may not only its equipped applications or stored files but also access, wiredly or wirelessly, a server or another electronic device to receive, in real-time, various pieces of information.

As various features are implemented in a single electronic device (e.g., a smartphone), smartphones have taken the place of electronic devices performing designated functions, such as music players, and are gradually invading the realm of video players or recording devices. As small electronic devices may have limited optical performance, the quality of captured images or videos may be enhanced by implementing a capturing function using a plurality of cameras or image sensors. For example, electronic devices, e.g., smartphones, are replacing compact cameras and are expected to take the place of high-end cameras, such as single-lens reflex cameras.

Auto-focusing is commonly equipped in compact electronic devices, e.g., smartphones, and optical image stabilization may contribute to enhancing the quality of captured images or videos. Optical image stabilization may move the lens assembly on the plane perpendicular to the optical axis, compensating for the movement of the electronic device due to a grip or a fixing device and thereby preventing or mitigating the shakes of the captured image or video. However, lens assembly driving-type optical image stabilization may be hard to equip in downsized electronic devices. For example, given the volume of the lens assembly, space for driving, and/or driving components for moving the lens assembly, lens assembly driving-type optical image stabilization may not be included in downsized electronic devices. In an embodiment, optical image stabilization may be implemented by moving the image sensor on the plane perpendicular to the optical axis while fixing the lens assembly on the optical axis. Optical image stabilization in a manner of driving the image sensor which is lighter than the lens assembly may make it easy to secure a space for permitting driving or a space for arranging driving components.

Meanwhile, the image sensor may be electrically connected to other circuit devices such as the processor through signal lines. High-capacity, high-efficiency, and/or high-rate signal lines may be used in transferring high-definition image or video-based signals to other circuit devices. Such signal lines may be implemented through a flexible printed circuit board. However, the repulsive force or elastic restoring force of the flexible printed circuit board may be an obstacle to optical image stabilization. For example, use of high-spec driving components or more power consumption may be required to overcome the repulsive force of the flexible printed circuit board in optical image stabilization.

The flexible printed circuit board may include: a first end portion coupled to the first circuit board, a second end portion coupled to the second circuit board, a plurality of extensions extending from the first end portion and connected to the second end portion, at least one slit disposed between two adjacent extensions among the plurality of extensions, and a plurality of conducting lines disposed in the plurality of extensions.

FIG.5is a cross-sectional view illustrating an example configuration in which a camera module405is disposed according to various embodiments.FIG.6is a diagram illustrating a plan view illustrating circuit boards453,455, and457of a camera module405according to various embodiments.

Referring toFIGS.5and6, a camera module405may include a lens assembly451, a first circuit board453including an image sensor453a, a second circuit board455including at least one connector455d, and/or a flexible printed circuit board457that electrically connects the first circuit board453and the second circuit board455.

According to various embodiments, the first area455aand the second area455bof the second circuit board455may be formed of a rigid material and be connected through a third area455cformed of a flexible material. However, various embodiments of the disclosure are not limited thereto, and the entire second circuit board455may be formed of a rigid material or a flexible material. In an embodiment, the second circuit board455may be formed of a flexible material and may be substantially a partial area of the flexible printed circuit board457, and a reinforcing plate (not shown) of a rigid material may be disposed in an area (e.g., the second area455b) in which the connector455dis disposed. In an embodiment, the first circuit board453may be formed of a rigid material, and an image sensor453amay be disposed on one surface thereof. In an embodiment, the first circuit board453may be formed of a flexible material and may be another partial area of the flexible printed circuit board457. When the first circuit board453is formed of a flexible material, a reinforcing plate (not shown) formed of a rigid material may be disposed in an area in which the image sensor453ais disposed.

According to various embodiments, an electronic device (e.g., the electronic device200or300ofFIGS.2,3and4) may include a decoration member383disposed to penetrate the rear plate380and providing a path through which external light is incident (hereinafter, referred to as a “capturing path”). A portion of the decoration member383may be disposed or coupled to the inner surface of the rear plate380, and another portion of the decoration member383may be shaped to penetrate the rear plate380to define a capturing path. In an embodiment, the capturing path is substantially in the shape of a hole penetrating the decoration member383, and the electronic device300may include a window381for transmitting light, thereby closing the hole of the decoration member383.

According to various embodiments, the camera module405and/or the lens assembly451may include at least one lens451aaligned on the optical axis O, and may be disposed inside a housing (e.g., the housing210ofFIG.2or the side structure310ofFIG.3) while facing the window381. The electronic device300and/or the processor120may perform autofocusing by moving the lens assembly451forward and backward in the optical axis O direction (e.g., the Z-axis direction). For example, a space in which the lens assembly451may move forward and backward may be provided inside the window381and/or the decoration member383.

According to various embodiments, the first circuit board453may be disposed to be movable on a plane substantially perpendicular to the optical axis O with respect to the window381or the lens assembly451while disposing the image sensor453aon the optical axis O. For example, the image sensor453aand/or the first circuit board453may move in at least one of two directions (e.g., the X-axis direction and the Y-axis direction) crossing each other on the plane substantially perpendicular to the optical axis O. In an embodiment, when the first circuit board453moves within one plane, the two directions may be substantially perpendicular to each other, and the relative positions or arrangement of the two directions may vary according to embodiments.

According to various embodiments, the electronic device300or a sensor module (e.g., a gyro sensor and/or an acceleration sensor as one of the sensor module176ofFIG.1) may be configured to detect a vibration of the housing210, and the electronic device300or the processor120may move the first circuit board453in at least one of two directions based on the vibration detected through the sensor module176. In an embodiment, the electronic device300or the processor120may identify whether the vibration detected by the sensor module176is the shaking of the user's hand, and may move the first circuit board453when it is identified as the shaking of the user's hand. Identifying vibration in a general use environment and hand shaking in capturing may be based on data related to the acceleration, direction, and/or strength of vibration, and such data may be stored in the electronic device300and/or memory (e.g., the memory130ofFIG.1). Here, the term “vibration” may refer, for example, to a tremor in a device for fixing the electronic device300or of the user's hand, and may cause quality deterioration of the captured image or video. For example, in capturing, the first circuit board453may move on the plane substantially perpendicular to the optical axis O, thereby compensating for vibration of the housing210caused by an external force and enhancing the quality of the captured image or image.

According to various embodiments, the electronic device300and/or the camera module405may further include a casing459, and the casing459may connect or couple the lens assembly451and the first circuit board453. For example, the lens assembly451may be disposed on the casing459to move forward and backward in the direction of the optical axis O, and the image sensor453amay be disposed in the casing459to be movable on the plane substantially perpendicular to the direction of the optical axis459. Although not illustrated, the casing459may be utilized as a structure for coupling or fixing the camera module405to the housing210or a printed circuit board (e.g., the side structure310or the printed circuit board340ofFIG.4).

According to various embodiments, the second circuit board455may include a connector455dcoupled to the printed circuit board340. For example, the camera module405may be electrically connected to the printed circuit board340substantially through the second circuit board455and/or the connector455d. According to an embodiment, the second circuit board455may include a first area455aconnected to the flexible printed circuit board457, a second area455bin which the connector455dis disposed, and/or a third area455celectrically connecting the first area455aand the second area455b. As mentioned above, the first area455aand the second area455bmay be formed of a rigid material, and the third area455cmay be formed of a flexible material. In an embodiment, the entire second circuit board455may be formed of any one of a rigid material and a flexible material, and when formed of a flexible material, the second circuit board455may be substantially a part of the flexible printed circuit board457.

According to various embodiments, the flexible printed circuit board457may include a first end portion457a, a second end portion457b, a plurality of extensions457c, at least one slit457g, and/or a plurality of conducting lines (e.g., the conducting lines1057aand1457aofFIG.20orFIG.32), and may electrically connect the first circuit board453and the second circuit board455. In an embodiment, the first end portion457amay be electrically coupled with the first circuit board453, and the second end portion457bmay be electrically coupled with the second circuit board455(e.g., the first area455a). In an embodiment, the first end portion457amay be at least partially fixed to the first circuit board453and the second end portion457bmay be at least partially fixed to the second circuit board455.

According to various embodiments, the extensions457cmay extend from the first end portion457ato be connected to the second end portion457b, and the slit(s)457gmay be formed between two adjacent extensions457c. For example, the extension portions457cand the slit(s)457gmay be alternately disposed. In an embodiment, the flexible printed circuit board457may be disposed substantially parallel to the plane on which the first circuit board453moves. In an embodiment, as an arrangement structure or an external force is applied, the flexible printed circuit board457may be at least partially deformable or movable. In this case, at least a portion of the flexible printed circuit board457may not be parallel to the plane on which the first circuit board453moves.

According to various embodiments, as the extensions457cand the at least one slit457gare alternately disposed between the first end portion457aand the second end portion457b, the repulsive force or elastic restoring force of the flexible printed circuit board457may be reduced compared to a structure in which the slits457gare not disposed. For example, compared with the structure in which the entire area in which the extensions457care arranged inFIG.6is formed of a film (e.g., the base film1057bofFIG.20) or an insulator (e.g., the insulator1057cofFIG.20), the flexible printed circuit board457in which the extensions457cand the slit(s)457gare alternately arranged may be more flexible. The elastic modulus k of a general flexible printed circuit board or where the slits457gare not disposed or the extension may be defined by Equation 1 below.

Here, “E” may refer to the longitudinal elastic modulus by the material of the film, the insulation layer, and/or the conducting line(s), “b” may refer to the thickness of the extension, “h” may refer to the width of the extension, and “1” may refer to the length of the extension. When 10 extensions457cand slits457gare alternately arranged while having the same width and/or length (e.g., the same wiring area) as that of a general flexible printed circuit board, e.g., inFIG.6, when the flexible printed circuit board457includes 10 extensions457c, the elastic modulus k of all the extensions457may be defined as Equation 2 below.

For example, as the number of the extensions457cand the slits457gincreases, the repulsive force and/or elastic restoring force by the flexible printed circuit board457and/or the extensions457cin optical image stabilization may be reduced, and optical image stabilization may be facilitated.

According to various embodiments, when viewed in a direction parallel to the optical axis O, e.g., the Z-axis direction ofFIG.5, the width of the slit(s)457gmay be smaller than the width w of the extensions457c. For example, although not limited to the illustrated numbers, one extension457cmay have a width w of about 120 μm, and the slit(s)457gmay have a width of about 25 μm and/or a width smaller than that.

According to various embodiments, a laser cutting method may be used in forming the slits457g. If the width of the slit457gincreases, forming one slit457grequires irradiating the slit457gwith the laser beam along the trajectory of the slit457gand, as the number of times in which the laser beam is radiated increases, manufacturing costs or time may increase. For example, the width w of one extension457cmay be selected considering the number of conducting lines1057aand1457adisposed in one extension457cor the widths of the conducting lines1057aand1457a, and the slit457gmay have a width (e.g., about 25 μm or less) that may be formed by laser cutting once on the flexible printed circuit board457.

According to various embodiments, the extension(s)457cmay include a first section457dand a second section457eand, according to an embodiment, may further include a third section457f. It is noted that dividing the extension(s)457cinto a plurality of sections is for convenience or brevity of description, and such dividing does not limit various embodiments of the disclosure. For example, the third section457fmay be a portion of any one of the first section457dor the second section457e. According to an embodiment, the first section457dmay extend along the first direction (e.g., the X-axis direction) and may be disposed side by side with a portion of the side surface (e.g., one side surface facing in the Y-axis direction) of the first circuit board453, and the second section457emay extend along the second direction (e.g., the Y-axis direction) crossing the first direction and may be disposed side by side with another portion (e.g., one side surface facing in the X-axis direction) of the side surface of the first circuit board453. As is described below, it is noted that the direction or position in which the first section457dor the second section457eis disposed may vary, and is not limited to the configuration mentioned herein.

According to various embodiments, the second section457emay be deformed or moved when the first circuit board453moves in the first direction (e.g., the X-axis direction), and the first section457dmay be deformed or moved when the first circuit board453moves in the second direction (e.g., the Y-axis direction). For example, the first section457dand the second section457emay allow the first circuit board453to move in two directions crossing each other in optical image stabilization, and the slits457gformed in the extension457c(e.g., the first section457dand the second section457e) may reduce the repulsive force or elastic restoring force of the flexible printed circuit board457generated in optical image stabilization.

According to various embodiments, the third section457fis a section connecting the first section457dand the second section457e, and may have a curved shape or an arc shape (or trajectory). As is described below, the third section457fmay be disposed to be inclined with respect to the first direction or the second direction to connect the first section457dand the second section457e. According to an embodiment, in optical image stabilization, when the first section457dand the second section457eare relatively deformed or moved, partial stress may be generated on the flexible printed circuit board457(e.g., the extension457c). The third section457fmay disperse the stress generated in optical image stabilization, thereby enhancing the durability or reliability of the flexible printed circuit board457. When viewed in plan view, e.g., when viewed in the Z-axis direction, the flexible printed circuit board457may further include curved portion(s) similar to the third section457f. For example, a connection portion between the extension457cand the first end portion457aor a connection portion between the extension457cand the second end portion457bmay have an arc shape similar to that of the third section457f, thereby dispersing stress that may occur on the flexible printed circuit board457.

In the following description, the components easy to understand from the description of the above embodiments are denoted with or without the same reference numerals and their detailed description may be skipped.

Referring toFIG.7, in the flexible printed circuit board557, the first section557dand the second section557eof the extension(s)557cmay be disposed in an area between the first circuit board453and the second circuit board455. For example, the first section557dmay extend from the first circuit board453or the first end portion457atoward the second circuit board455in the first direction (e.g., the X-axis direction), and the second section557emay be disposed adjacent to the second circuit board455while extending between the first section557dand the second end portion457bin the second direction (e.g., the Y-axis direction).

FIG.8is a diagram illustrating a plan view illustrating circuit boards453,455, and657of a camera module (e.g., the camera module405ofFIG.5) according to various embodiments.

Referring toFIG.8, the camera module405may include a pair of flexible printed circuit boards657, and the first sections657dof the flexible printed circuit boards657(e.g., the extensions457cofFIG.6) may extend along a first direction (e.g., the X-axis direction) and may be disposed on the +Y side and/or the −Y side of the first circuit board453, respectively. In an embodiment, the second section657emay extend from the first section657dalong the second direction (e.g., the Y-axis direction) and may be disposed on the −X side of the first circuit board453. In an embodiment, a portion of the flexible printed circuit board657or the extension457cofFIG.6may further include a section (hereinafter, referred to as a “fourth section659”) forming a zigzagged shape, a “U” shape, or an “S” shape between the first circuit board453and the second circuit board455. Compared with the embodiment ofFIG.6or7, the fourth section659may extend, e.g., the length of the flexible printed circuit board657or the extension657c, and as described above through Equation 1 or Equation 2, as the length is extended, the repulsive force of the flexible printed circuit board657or the extension657cmay be reduced in optical image stabilization.

FIG.9is a diagram illustrating a plan view illustrating circuit boards453,455, and757of a camera module (e.g., the camera module405ofFIG.5) according to various embodiments.

Referring toFIG.9, the flexible printed circuit board757may be disposed between the first circuit board453and the second circuit board455, and may have a zigzagged shape or an “S” shape. For example, the flexible printed circuit board757or the extension757cmay include at least one first section757dextending in a direction crossing the X-axis direction or the Y-axis direction, and a second section757eextending in a direction crossing the first section. The zigzagged shape or the “S” shape may be used to sufficiently secure the length of the flexible printed circuit board757or the extension757cwithin the limited arrangement area, thereby reducing the repulsive force of the flexible printed circuit board757or the extension757cin optical image stabilization.

FIG.10is a diagram illustrating a plan view illustrating circuit boards453,455, and857of a camera module (e.g., the camera module405ofFIG.5) according to various embodiments.

Referring toFIG.10, the flexible printed circuit board857may include extensions857cextending in different directions from a first end portion857acoupled to the first circuit board453. The extensions857cmay include, e.g., at least one slit (e.g., the slit457gofFIG.6), and may include a first section857dextending in a first direction (e.g., the X-axis direction) and second sections857eextending from two opposite ends of the first section857din a second direction (e.g., the Y-axis direction). In an embodiment, a pair of first sections857dmay be provided to be disposed on the +Y side and the −Y side of the first circuit board453, and may be connected to the first end portion857athrough any one of the second sections857e. The first section857dor the second section857emay be disposed substantially along the circumference of the first circuit board453or around any one of the side surfaces of the first circuit board453. In the illustrated embodiment, when viewed in plan view (e.g., when viewed in the Z-axis direction or the optical axis O direction ofFIG.5), the first section857dor the second section857emay at least partially overlap the first circuit board453. In the shape or arrangement of the flexible printed circuit board857in the embodiment illustrated inFIG.10, as compared with the embodiment illustrated inFIG.6, the flexible printed circuit board857or the extension857cmay have an extended length, thereby reducing the repulsive force of the flexible printed circuit board857or the extension857cin optical image stabilization.

FIG.11is a diagram illustrating a plan view illustrating an arrangement of extensions457cin a camera module (e.g., the camera module405ofFIG.5) according to various embodiments.

Referring toFIG.11, a slit (e.g., the slit(s)457gofFIG.6) may be formed to substantially correspond to the entire length of the extension457c. In an embodiment, since the flexible printed circuit board (e.g., the flexible printed circuit board457or the extension457cofFIG.6) has flexibility, a laser cutting process may be performed in a fixed state using designated equipment. For example, a laser cutting process may be performed in a state capable of suppressing thermal deformation of the flexible printed circuit board457or the extension457c. However, when the width of the extension457cis reduced to about 120 μm, it may be difficult to secure a space or area capable of irradiating with laser beams while stably fixing the flexible printed circuit board457or the extension457c.

FIG.12is a diagram illustrating a plan view illustrating another example arrangement of extensions457cin a camera module (e.g., the camera module405ofFIG.5) according to various embodiments.FIG.13is a diagram illustrating a plan view illustrating another example arrangement of extensions457cin a camera module405according to various embodiments.

The bridge957hmay be, e.g., a portion of a base film (e.g., the base film1057bofFIG.20) or an insulation layer (e.g., the insulation layer1057cofFIG.20) of the flexible printed circuit board457. The bridge957hmay be disposed between the first section457dand the second section457eas illustrated inFIG.12, and/or may be disposed in each of the first section457dand the second section457eas illustrated inFIG.13. The number and arrangement position of the bridges957hmay be variously selected or combined considering the repulsive force of the flexible printed circuit board457or suppressing deformation in the laser cutting process.

FIG.14is a diagram illustrating a plan view illustrating another example arrangement of extensions457cin a camera module (e.g., the camera module405ofFIG.5) according to various embodiments.

Referring toFIG.14, the bridge957hofFIG.12or13may be replaced with a dummy substrate957i. For example, the dummy substrate957iis a type of printed circuit board formed of a rigid material, and may be disposed across at least some of the slits457gon the extension457cto connect adjacent extensions457c. Similar to the embodiment ofFIGS.12and13, the shape, number, and/or position of the dummy substrate957imay be variously selected or combined considering suppressing the repulsive force of the flexible printed circuit board457or deformation in the laser cutting process.

FIG.15is a diagram illustrating a plan view illustrating an arrangement of insulating protrusion(s)957jin a camera module (e.g., the camera module405ofFIG.5) according to various embodiments.FIG.16is a diagram illustrating a plan view illustrating another example of the arrangement of an insulating protrusion(s)957jin a camera module405according to various embodiments.FIG.17is a diagram illustrating a plan view illustrating another example of the arrangement of an insulating protrusion(s)957jin a camera module405according to various embodiments.

Referring toFIGS.15,16and17, the flexible printed circuit board457may further include at least one insulating protrusion957jformed on a surface (e.g., a surface facing in the +Z direction or the −Z direction ofFIG.5on the extension457c). The insulating protrusion957jprotrudes from the surface of the flexible printed circuit board457, and may contact another structure when a portion (e.g., the first section457dor the second section457eofFIG.6) of the flexible printed circuit board457is deformed or moved in optical image stabilization. The term “other structure” may include, e.g., the casing459ofFIG.5or the first circuit board453ofFIG.10.

According to various embodiments, if there is no insulating protrusion957j, the flexible printed circuit board457may make surface contact with another structure while being deformed or moved in optical image stabilization, and the frictional force due to the surface contact may disturb optical image stabilization. According to an embodiment, as the insulating protrusion957jprotrudes from the surface of the flexible printed circuit board457, the contact area of the flexible printed circuit board457may be reduced even when the flexible printed circuit board457comes into contact with another structure. For example, the insulating protrusion957jmay smoothly perform optical image stabilization by preventing or alleviating friction. In an embodiment, the insulating protrusion957jmay be disposed considering a portion deformed or moved in optical image stabilization, and may be formed of a material such as silk screen printing ink. In an embodiment, when the flexible printed circuit board457includes the bridge957hor the dummy board957i, the insulating protrusion957jmay be formed on the surface of the bridge957hor the dummy board957i.

For example, as illustrated inFIG.6, the connection portion may include a third section457fof a curved or arc trajectory, and as illustrated inFIG.18, the third section457fmay be omitted, and the extension457cand the first end portion457amay be directly connected, or the first section457dand the second section457emay be directly connected. In an embodiment, as illustrated inFIG.19, the flexible printed circuit board457may include a plurality of third sections457fextending in a direction inclined with respect to the first section457dand the second section457e. One of the third sections457fmay connect the extension457cand the first end portion457a, and the other of the third sections457fmay connect the first section457dand the second section457e.

The base film1057bmay be formed of, e.g., a polymer material such as polyimide, and the insulation layer1057cmay be formed of a material having a permittivity of about 2.5 or more and about 4.5 or less (e.g., polyimide or liquid crystal polymer (LCP)). In an embodiment, the base film1057bmay be formed of a material forming the insulation layer1057c. Although it may vary depending on embodiments, the base film1057bor the insulation layer1057cmay have a thickness of about 20 μm or more and about 50 μm or less.

According to various embodiments, the conducting lines1057amay be disposed in pairs in one extension1057, and may be formed of an electrically conductive material such as copper (Cu), gold (Au), or stainless steel. In an embodiment, the conducting line1057amay have a thickness of about 5 μm or more and about 30 μm or less and may be disposed on the surface of the base film1057bwhile being surrounded by the insulation layer1057c. According to an embodiment, at least one pair of conducting lines1057amay be disposed in one extension1057. When the pair of conducting lines1057aare disposed in one extension1057, the two conducting lines1057cmay form a power source-power source or power source-ground combination and, in an embodiment, the two conducting lines1057cmay form a signal-signal or signal-ground combination. The flexible printed circuit board457may include a plurality of extensions1057. The flexible printed circuit board457may transmit power or signals between the camera module and the processor (e.g., the camera module405ofFIG.5and the processor120ofFIG.1) using the conducting lines1057adisposed in each extension1057, and may match the MIPI or a camera serial interface (CSI) in transmitting power or signals.

According to various embodiments, the two conducting lines1057ain one extension1057may be used as a reference for impedance matching with respect to each other, and impedance matching may be performed with differential signals or a single signal. In this impedance matching, the permittivity and thickness of the base film1057band the insulation layer1057cand/or the thickness of the conducting line1057amay be considered. As is described below, one extension1057may be provided with at least one conductive layer (e.g., the conductive layer1057dofFIGS.21to23) in addition to the two conducting lines, and the conductive layer1057dmay be used as a reference for impedance matching of the conducting lines1057a. According to an embodiment, through such impedance matching, the flexible printed circuit board457may provide a high-capacity, high-rate signal transmission environment matching the MIPI or CSI between the first circuit board and the second circuit board (e.g., the first circuit board453and the second circuit board455ofFIG.6).

FIGS.21,22,23,24,25,26,27,28,29and31are cross-sectional views illustrating extensions (e.g., the flexible printed circuit board457or extension457cofFIG.6) in a camera module (e.g., the camera module405ofFIG.5) according to various embodiments.

Referring toFIGS.21,22and23, the flexible printed circuit board457or the extension1057may include conductive layer(s)1057ddisposed on at least one of an upper surface (e.g., a surface of the insulation layer1057c) or a lower surface (e.g., a surface of the base film1057b). The conductive layer(s)1057dmay be provided as, e.g., a ground conductor or an electromagnetic shielding structure, and may have a width greater than that of the conducting line1057a. In an embodiment, the conductive layer1057dmay have substantially the same width as the base film1057bor the insulation layer1057c. For example, when viewed in a direction (e.g., the Z-axis direction ofFIG.5) parallel to the optical axis O, the edge of the conductive layer1057dmay be at least partially aligned with the edge of the extension1057(e.g., the edge of the base film1057bor the insulation layer1057c). In an embodiment, the conducting lines1057amay be formed by forming a metal layer similar to the conductive layer1057don the surface of the base film1057band then partially removing the same. In an embodiment, the conductive layer1057dformed on the base film1057bmay set a position or area for irradiating with a laser beam to form a position or slit (e.g., the slit457gofFIG.6) forming the conducting line1057a. In an embodiment, at least one of the conductive layers1057dmay be utilized as a reference for impedance matching of the conducting lines1057a.

Referring toFIGS.24and25, the extension1157may include conducting lines1157adisposed on the upper surface and the lower surface, respectively, of the base film1157b, and the insulation layers1157cmay be formed on two opposite surfaces of the base film1157bto surround the conducting lines1157a. According to an embodiment, the flexible printed circuit board457and/or the extension1157may further include conductive layer(s)1157dformed on at least one of an upper surface or a lower surface (e.g., a surface of the insulation layer1157c). The conductive layer1157dmay be provided as, e.g., a ground conductor or an electromagnetic shielding structure. Similar to the previous embodiment, any one of the conducting lines1157amay be utilized as a reference for impedance matching of the other. When the conductive layer1157dis provided, impedance matching of the conducting lines1157amay be performed with respect to the conductive layer1157d.

Referring toFIGS.26,27,28and29, the extension1257may include one conducting line1257adisposed on the surface of the base film1257bwhile being surrounded by the insulation layer1257c, and another conducting line1257adisposed on the surface of the insulation layer1257cwhile being surrounded by another insulation layer1257c. For example, in one extension1257, the conducting lines1257amay be disposed in different layers. In an embodiment, the extension1257may further include conductive layer(s)1257ddisposed on at least one of an upper surface and a lower surface. The conductive layer1257dmay be provided as, e.g., a ground conductor or an electromagnetic shielding structure. Similar to the previous embodiment, any one of the conducting lines1257amay be utilized as a reference for impedance matching of the other. When the conductive layer1257dis provided, impedance matching of the conducting lines1257amay be performed with respect to the conductive layer1257d.

Referring toFIGS.30and31, the extension1357may include a first conductive layer1357dand base films1357bcoupled to face each other with the first conductive layer1357dinterposed therebetween. The conducting lines1357amay be disposed on surfaces, respectively, of any one of the two base films1357bwhile being surrounded by the insulation layer1357c. According to an embodiment, the extension1357may further include the second conductive layer(s)1357eprovided on at least one of the upper surface or the lower surface. In an embodiment, when the first conductive layer1357dand/or the second conductive layer1357eare viewed in a direction (e.g., the Z-axis direction ofFIG.5) parallel to the optical axis (e.g., the optical axis O ofFIG.5), the edges of the conductive layer(s)1357dand3157emay be at least partially aligned with the edge of the extension1357(e.g., the edge of the base film1357bor the insulation layer1357c). For example, the first conductive layer1357dmay be visually exposed (e.g., visible) to the outside of the extension1357between the base films1357b.

In the above-described embodiment, the conductive layers (e.g., the conductive layers1057dofFIGS.21to23) may define a position or area where a laser beam is to be radiated to form the position or slit (e.g., the slit457gofFIG.6) where the conducting lines (e.g., the conducting line1057aofFIGS.21to23) are to be formed. When the conductive layers1057dare provided on the upper and lower surfaces of the flexible printed circuit board457or the extensions457cand1057, the conducting lines1057amay be disposed substantially in an area between the conductive layers1057d, and the conductive layers1057dmay function as an electromagnetic shielding structure. For example, while high-rate signal transmission is performed through the conducting lines1057a, the conductive layers1057dmay provide a stable signal transmission environment.

FIG.32is a diagram illustrating a plan view illustrating connection of conducting lines1457a(e.g., the conducting line1057aofFIGS.20to23) in a camera module (e.g., the camera module405ofFIG.5) according to various embodiments.

Referring toFIG.32, as described above, at least one pair of conducting lines1457amay be disposed in one extension457cand1057, and two or more conducting lines selected from among the conducting lines1457adisposed in different extensions457cand1057may be connected in parallel P. For example, the conducting lines1457amay be substantially disposed in the extensions457cand1057, respectively, and at least one pair of the conducting lines1457amay be merged at the first end portion457aor the second end portion457b(e.g., the first circuit board453or the second circuit board455ofFIG.6) to be connected in parallel P. According to an embodiment, when power or a signal is transferred between the first end portion457aand the second end portion457b, as the width of the conducting line1457adecreases, the line resistance may increase, so that the power efficiency may be further reduced. For example, power loss may increase in supplying power through the flexible printed circuit board1457. In the above-described embodiment, by forming the slit457gin the flexible printed circuit board1457, it is possible to reduce the repulsive force in optical image stabilization. However, as the width of the extension457cdecreases, the width of the conducting line1457ais also limited, and thus the line resistance may increase. According to various embodiments of the disclosure, it is possible to prevent and/or reduce power loss due to line resistance by connecting some selected from among the conducting lines1457a, e.g., the conducting lines1457adisposed in at least two adjacent extensions457c, in parallel P. For example, by supplying power using the conducting lines1457aconnected in parallel P, it is possible to prevent and/or reduce a decrease in efficiency in transmitting power through the flexible printed circuit board1457.

According to various example embodiments, an electronic device and/or a processor (e.g., the electronic device101,102,104,200, or300ofFIGS.1to4and/or the processor120) may include a camera module (e.g., the camera module180,205,212,213, or405ofFIG.1to3or5) that receives external light from one surface or another surface (e.g., the first surface210A or the second surface210B of the housing210ofFIGS.2and3) of the housing, and the camera module may include the above-described flexible printed circuit board (e.g., the flexible printed circuit board457or1457ofFIG.6or32) and/or an extension (e.g., the extension457cofFIG.6or32). For example, in the capturing mode, the electronic device and/or the processor may obtain an object image or video using the camera module. In an embodiment, when the camera module has an optical image stabilization function, the electronic device and/or the processor may detect a vibration of the housing using a sensor module (e.g., the sensor module176ofFIG.1), e.g., a gyro sensor or an acceleration sensor, and may perform optical image stabilization based on the detected vibration. The term “optical image stabilization” may refer, for example, to, an operation of horizontally moving a first circuit board (e.g., the first circuit board453ofFIG.6) on the plane substantially perpendicular to the optical axis.

According to various embodiments, the vibration of the housing may be caused by a vibration generated in a general use environment and a vibration of a fixing device or the user's body in the actual capturing mode. The electronic device and/or the processor may identify whether the vibration detected through the sensor module is the shaking of the user's hand. For example, data about the direction, speed, or amplitude of the vibration caused by the fixing device or the shaking of the hand may be stored in the memory, and the electronic device and/or the processor may identify the vibration in a general use environment and the shaking of the fixing device or the user's hand by comparing the detected vibration with the data stored in the memory.

According to various embodiments, in optical image stabilization, the first circuit board may move or reciprocate along at least one of the first direction and the second direction (e.g., the X-axis direction or the Y-axis direction ofFIG.6). The moving or reciprocating direction of the first circuit board may be opposite to the direction of the vibration caused by the shaking of the hand. In an embodiment, when the first circuit board moves in the first direction (e.g., the X-axis direction ofFIG.6), the first portion (e.g., the second section457eofFIG.6) of the extension may be moved or deformed, allowing the movement of the first circuit board. When the first circuit board moves in the second direction (e.g., the Y-axis direction ofFIG.6), the second portion (e.g., the first section457dofFIG.6) of the extension may be moved or deformed, allowing the movement of the first circuit board. In an embodiment, when the first circuit board moves in a direction crossing the first direction and the second direction, the first portion and the second portion of the extension may be simultaneously moved or deformed, allowing the movement of the first circuit board.

According to various example embodiments of the disclosure, a camera module (e.g., the camera module180,205,212,213, or405FIG.1to3or5) and/or an electronic device (e.g., the electronic device101,102,104,200, or300ofFIGS.1to4) including the same may comprise: a lens assembly (e.g., the lens assembly451ofFIG.5) including at least one lens (e.g., the lens451aofFIG.5) aligned on an optical axis (e.g., the optical axis O ofFIG.5), a first circuit board (e.g., the first circuit board453ofFIG.5or6) including an image sensor (e.g., the image sensor453aofFIG.5or6) disposed on the optical axis and disposed to be movable in two directions (e.g., the X-axis direction and the Y-axis direction), the two directions crossing each other on a plane perpendicular to the optical axis, a second circuit board (e.g., the second circuit board455ofFIG.6) having at least one connector (e.g., the connector455dofFIG.6) disposed thereon, and a flexible printed circuit board (e.g., the flexible printed circuit board457or1457ofFIG.6or32) electrically connecting the first circuit board and the second circuit board. The flexible printed circuit board may include a first end portion (e.g., the first end portion457aofFIG.6or32) coupled to the first circuit board, a second end portion (e.g., the second end portion457bofFIG.6or32) coupled to the second circuit board, a plurality of extensions (e.g., the extension457cofFIG.6or32) extending from the first end portion and connected to the second end portion, at least one slit (e.g., the slit457gofFIG.6) disposed between two adjacent extensions among the plurality of extensions, and a plurality of conducting lines (e.g., the conducting line1057aor1457aofFIG.20or14) disposed in the plurality of extensions. Two or more selected from among the conducting lines disposed in different extensions may be connected in parallel.

According to various example embodiments, the conducting lines connected in parallel may be configured to be merged on the first circuit board to supply power.

According to various example embodiments, at least a pair of conducting lines may be disposed in one extension.

According to various example embodiments, the conducting lines in one extension may be configured to be impedance-matched with respect to each other.

According to various example embodiments, when viewed in a direction parallel to the optical axis, a width of the slit may be less than a width of the extension.

According to various example embodiments, the extension may include a first section (e.g., the first section457dofFIG.6) extending along a first direction of the two directions crossing each other and a second section (e.g., the second section457eofFIG.6) extending along a second direction of the two directions crossing each other.
