Technical Field

[0003] The present disclosure generally relates to a dynamic flexible circuit for a camera with a movable image sensor. Background Art

[0004] The advent of small mobile multi-purpose devices such as smart phones and tablet or slate devices has led to a need for high-resolution, small-form-factor cameras to be integrated into the devices. Some cameras may incorporate an optical image stabilization (OIS) mechanism that can sense and react to external stimuli / disturbances by adjusting the position of the optical lens on the X-axis and / or Y-axis in an attempt to compensate for unwanted motion of the lens. In addition, some cameras may incorporate an autofocus (AF) mechanism by which the focus of an object can be adjusted so that the object plane in front of the camera is focused at the image plane to be captured by the image sensor. In some such AF mechanisms, the optical lens is moved as a single rigid body along the optical axis of the camera to refocus the camera. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] This specification includes references to "one embodiment" or "an embodiment." The appearance of the phrase "in one embodiment" or "in an embodiment" does not necessarily refer to the same embodiment. The particular features, structures or characteristics may be combined in any suitable manner consistent with the present disclosure.

[0014] The term "comprising" is open ended. As used in the appended claims, the term does not exclude additional structures or steps. Consider the following cited claim: "an apparatus comprising one or more processor units..." Such a claim does not exclude the apparatus from including additional components (e.g., a network interface unit, a graphics circuit, etc.).

[0015] "Configured to", various units, circuits or other components may be described or described as "configured to" perform one or more tasks. In such contexts, "configured to" is used to imply a structure (e.g., a circuit) that performs the one or more tasks during operation by indicating that the unit / circuit / component includes the structure. In this way, the unit / circuit / component is said to be configured to perform the task even when the specified unit / circuit / component is currently inoperable (e.g., not turned on). The units / circuits / components used with the "configured to" language include hardware-e.g., circuits, memories storing executable program instructions to implement operations, etc. The reference to a unit / circuit / component "configured to" perform one or more tasks is explicitly intended not to invoke the sixth paragraph of 35 U.S.C. §112 for the unit / circuit / component. In addition, "configured to" may include a general structure (e.g., a general circuit) manipulated by software and / or firmware (e.g., an FPGA or a general processor executing software) to operate in a manner capable of performing one or more tasks to be solved. "Configured to" may also include adapting a manufacturing process (eg, a semiconductor fabrication facility) to produce a device (eg, an integrated circuit) suitable for implementing or performing one or more tasks.

[0016] "First," "second," etc. As used herein, these terms act as labels for the nouns that precede them, and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). For example, a buffer circuit may be described herein as performing a write operation of a "first" value and a "second" value. The terms "first" and "second" do not necessarily imply that the first value must be written before the second value.

[0017] "Based on". As used herein, this term is used to describe one or more factors that influence a determination. This term does not exclude additional factors that influence a determination. That is, a determination may be based solely on these factors or at least in part on these factors. Consider the phrase "A is determined based on B". In this case, B is a factor that influences the determination of A, and such a phrase does not exclude that the determination of A may also be based on C. In other examples, A may be determined based solely on B.

[0018] It will also be understood that, although the terms "first", "second", etc. may be used to describe various elements in this article, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, without departing from the expected scope, the first contact may be referred to as the second contact, and similarly, the second contact may be referred to as the first contact. Both the first contact and the second contact are contacts, but they are not the same contact.

[0019] The terms used in the description herein are only for describing specific embodiments and are not intended to be limiting. As used in the specification and the appended claims, the singular forms of "one", "a kind of" and "the" are intended to also cover the plural forms, unless the context clearly indicates otherwise. It will also be understood that the term "and / or" used herein refers to and covers any and all possible combinations of one or more items in the items listed in association. It will also be understood that the terms "including" and / or "comprising" when used in this specification specify the presence of stated features, integers, steps, operations, elements and / or parts, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, parts and / or their grouping.

[0020] As used herein, the term "if" may be interpreted to mean "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined that" or "if [a stated condition or event] is detected" may be interpreted to mean "upon determining that" or "in response to determining that" or "upon detecting [a stated condition or event]" or "in response to detecting [a stated condition or event]," depending on the context. DETAILED DESCRIPTION

[0021] Various embodiments described herein relate to flexible circuits that can be used in cameras with movable image sensors (also referred to herein as "dynamic flexible circuits"). In some examples, a camera may include a dynamic flexible circuit, a stationary flexible circuit, a movable image sensor, an actuator, and / or one or more optical elements. The image sensor may be configured to capture light that has passed through the optical element. The actuator may be configured to move the image sensor relative to the optical element, for example, to provide autofocus (AF) and / or optical image stabilization (OIS) functionality. Additionally or alternatively, the actuator may be configured to move one or more of the optical elements relative to the image sensor, for example, to provide AF and / or OIS functionality. In some non-limiting examples, the actuator may be configured to move the image sensor orthogonal to a plane defined by the image sensor. Additionally or alternatively, the actuator may be configured to move the image sensor parallel to a plane defined by the image sensor.

[0022] In various embodiments, the dynamic flexible circuit may include one or more fixed end portions, a movable end portion, and an intermediate portion. The fixed end portion may be connected to the stationary flexible circuit. The movable end portion may be coupled to the image sensor so that the movable end portion moves with (e.g., synchronized with) the image sensor. The intermediate portion may extend from each of the fixed end portions to the movable end portion. The intermediate portion may be configured to allow the movable end portion to move relative to the fixed end portion (e.g., with the image sensor). In some embodiments, the dynamic flexible circuit may be configured to transmit electrical signals (e.g., power and / or control signals) along at least a portion of the electrical connection path between the stationary flexible circuit and the movable image sensor. As will be referenced herein Figures 1 to 6 As discussed, the middle portion of the dynamic flex circuit may include one or more straight regions and one or more curved regions.

[0023] In some embodiments, the dynamic flexible circuit can be subjected to high strain and / or cyclic loading conditions. Figures 5 and 6 As discussed, the reinforcement arrangement can be used to reduce stress and strain at the bend area. Additionally or alternatively, one or more of the straight areas of the dynamic flex circuit can be designed with sufficient auxiliary bundle loops to reduce stress and strain at the bend area. Additionally or alternatively, the bend radius of the bend area can be designed to reduce stress and strain at the bend area.

[0024] Reference will now be made in detail to the embodiments, examples of which are illustrated in the accompanying drawings. In the detailed description that follows, numerous specific details are given in order to provide a thorough understanding of the present disclosure. However, it will be apparent to one of ordinary skill in the art that some embodiments may be implemented without these specific details. In other cases, well-known methods, processes, components, circuits, and networks are not described in detail so as not to unnecessarily obscure various aspects of the embodiments.

[0025] As described above, various embodiments include a dynamic flex circuit for a camera with a movable image sensor. Figure 1 A schematic block diagram of some components of a camera 100 including an example of such a dynamic flexible circuit 102 is shown. Figure 1 A perspective view of the dynamic flex circuit 102 is shown. Figure 1 The exemplary XYZ coordinate system shown in is used to discuss various aspects of components and / or systems and may be applicable to embodiments described throughout the present disclosure.

[0026] According to various embodiments, the camera 100 may include a dynamic flexible circuit 102, a stationary flexible circuit 104 (e.g., a flexible circuit of a module of the camera 100), a movable image sensor 106, one or more actuators 108, one or more optical elements 110, and / or a suspension arrangement 112. The image sensor 106 may be configured to capture light that has passed through the optical element 110. The actuator 108 may be configured to move the image sensor 106 relative to the optical element 110, for example, to provide AF and / or OIS functionality. Additionally or alternatively, the actuator 108 may be configured to move one or more of the optical elements 110 relative to the image sensor 106, for example, to provide AF and / or OIS functionality. In some non-limiting examples, the actuator 108 may be configured to move the image sensor 106 orthogonal to a plane defined by the image sensor 106 (e.g., in a Z-axis direction). Additionally or alternatively, actuator 108 may be configured to move image sensor 106 parallel to a plane defined by image sensor 106 (eg, in an XY plane direction).

[0027] In various embodiments, the dynamic flexible circuit 102 may include one or more fixed end portions 114, one or more movable end portions 116, and / or one or more intermediate portions 118. Figure 1 As indicated in the perspective view of the dynamic flexible circuit 102 in FIG. 1 , in some non-limiting examples, the dynamic flexible circuit 102 may include fixed end portions 114 (a) and 114 (b), a movable end portion 116, and an intermediate portion 118. The fixed end portions 114 (a) and 114 (b) may be connected to the stationary flexible circuit 104. The movable end portion 116 may be coupled to the image sensor 106 so that the movable end portion 116 moves with (e.g., synchronized with) the image sensor 106. The intermediate portion 118 may extend from each of the fixed end portions 114 (a) and 114 (b) to the movable end portion 116. The intermediate portion 118 may be configured to allow the movable end portion 116 to move relative to the fixed end portions 114 (a) and 114 (b) (e.g., with the image sensor 106). In some embodiments, dynamic flex circuit 102 can be configured to carry electrical signals (eg, power and / or control signals) along at least a portion of the electrical connection path between stationary flex circuit 104 and movable image sensor 106 .

[0028] In some embodiments, the fixed end portions 114(a) and 114(b) of the dynamic flex circuit 102 may be fixedly attached to the stationary flex circuit 104 (which may be considered a stationary structure) and / or fixedly attached to another stationary structure of the camera 100 (e.g., Figure 2For example, the fixed end portions 114(a) and 114(b) can be attached to one or more stationary structures and can provide electrical connections between the fixed end portions 114(a) and 114(b) and the stationary flexible circuit 104 via the stationary structures. In some embodiments, each of the fixed end portions 114(a) and 114(b) can have a first side attached to the stationary flexible circuit 104 and a second side (e.g., opposite the first side) attached to another stationary structure.

[0029] According to some embodiments, the fixed end portion 114(a) and / or the fixed end portion 114(b) of the dynamic flexible circuit 102 may include corresponding electrical connection pads (e.g., exposed copper pads) that may be electrically connected (e.g., via hot bar soldering) to corresponding electrical connection features of the stationary flexible circuit 104. In some embodiments, the fixed end portion 114(a) and / or the fixed end portion 114(b) may define a corresponding plane that is orthogonal to a corresponding plane defined by the movable end portion 116 and / or the image sensor 106, e.g., as Figure 1 However, it is contemplated that in some embodiments, the fixed end portion 114(a) and / or the fixed end portion 114(b) may define respective planes that are oriented differently relative to (e.g., parallel to) respective planes defined by the movable end portion 116 and / or the image sensor 106.

[0030] In various embodiments, the movable end portion 116 of the dynamic flexible circuit 102 can be coupled to the image sensor 106. For example, the image sensor 106 can be attached to (or otherwise coupled to) the base of the camera 100 (e.g., Figure 2 The substrate 206 in the embodiment of the present invention can be provided, and the movable end portion 116 can be attached to the substrate. In some embodiments, the movable end portion 116 can be electrically connected to the image sensor 106 via the substrate and / or one or more other intervening components.

[0031] According to various embodiments, the middle portion 118 of the dynamic flexible circuit 102 may extend from the movable end portion 116 to each of the fixed end portions 114(a) and 114(b). The middle portion 118 may include one or more straight regions and / or one or more curved regions. Figure 1As noted in , in some non-limiting examples, the middle portion 118 may include a first straight region 120 (a), a second straight region 120 (b), a third straight region 120 (c), and / or a fourth straight region 120 (d). In addition, the middle portion 118 may include a first curved region 122 (a), a second curved region 122 (b), and / or a third curved region 122 (c). The first curved region 122 (a) may interconnect the first straight region 120 (a) with the second straight region 120 (b). The second curved region 122 (b) may interconnect the second straight region 120 (b) with the third straight region 120 (c). The third curved region 122 (c) may interconnect the second straight region 120 (b) with the fourth straight region 120 (c). According to some examples, a pair of adjacent straight regions (e.g., first straight region 120(a) and second straight region 120(b)) may be positioned relative to each other at respective non-zero bend angles (e.g., 90 degrees) so as to form a bend via a bend region (e.g., first bend region 122(a)). In various embodiments, the bend angle may change slightly when image sensor 106 is moved, but the bend may exist throughout the potential range of motion of image sensor 106. In some non-limiting examples, the bend angle may be in the range of 45 degrees to 135 degrees. In some other non-limiting examples, the bend angle may be in the range of 60 degrees and 120 degrees.

[0032] In some embodiments, the first straight region 120(a) may define a plane parallel to the XY plane, and may have a longest dimension extending from the movable end portion 116 to the first curved region 122(a) along the X-axis direction. The second straight region 120(b) may define a plane parallel to the YZ plane, and may have a longest dimension extending from the second curved region 122(b) to the third curved region 122(c) along the Y-axis direction. The third straight region 120(c) may define a plane parallel to the XZ plane, and may have a longest dimension extending from the second curved region 122(b) to the fixed end portion 114(a) along the X-axis direction. The fourth straight region 120(d) may define a plane parallel to the XZ plane, and may have a longest dimension extending from the third curved region 122(c) to the fixed end portion 114(b) along the X-axis direction. Figure 1 , the dynamic flex circuit 102 can be symmetrical (eg, about a plane parallel to the XZ plane). However, the dynamic flex circuit 102 can be asymmetrical about one or more planes parallel to the XZ plane, the YZ plane, and / or the XZ plane.

[0033] According to some embodiments, the longest dimension of the first straight region 120(a) can be sized to reduce the stiffness of the dynamic flex circuit 102 along the Z-axis direction, for example, to allow the movable end portion 116 to move along the Z-axis direction. The longest dimension of the second straight region 120(b) can be sized to reduce the stiffness of the dynamic flex circuit 102 along the X-axis direction, for example, to allow the movable end portion 116 to move along the X-axis direction. The longest dimension of the third straight region 120(c) can be sized to reduce the stiffness of the dynamic flex circuit 102 along the Y-axis direction, for example, to allow the movable end portion 116 to move along the Y-axis direction. Similarly, the longest dimension of the fourth straight region 120(d) can be sized to reduce the stiffness of the dynamic flex circuit 102 along the Y-axis direction, for example, to allow the movable end portion 116 to move along the Y-axis direction.

[0034] In some embodiments, the first bending region 122 (a) may be a region where the dynamic flexible circuit 102 bends around a first axis. The second bending region 122 (b) may be a region where the dynamic flexible circuit 102 bends around a second axis. The third bending region 122 (c) may be a region where the dynamic flexible circuit 102 bends around a third axis. In some embodiments, one or more of these axes may intersect one or more of the other axes. In some non-limiting examples, the first axis (corresponding to the first bending region 122 (a)) may intersect the second axis (corresponding to the second bending region 122 (b)) and / or the third axis (corresponding to the third bending region 122 (c)). In some non-limiting examples, the first axis may be orthogonal to each of the second axis and the third axis. In addition, in some embodiments, one or more of these axes may be parallel to one or more of the other axes. In some non-limiting examples, the second axis may be parallel to the third axis. According to some non-limiting examples, the first axis may be parallel to the Y axis (and / or parallel to a corresponding plane defined by the movable end portion 116 and / or the image sensor 106), the second axis may be parallel to the Z axis (and / or orthogonal to a corresponding plane defined by the movable end portion 116 and / or the image sensor 106), and / or the third axis may be parallel to the Z axis (and / or orthogonal to a corresponding plane defined by the movable end portion 116 and / or the image sensor 106).

[0035] In some embodiments, one or more of the straight regions and / or curved regions of the dynamic flex circuit 102 can be at least partially divided into a plurality of "legs." As a non-limiting example, a portion of the first straight region 120(a) can be divided into two legs 124(a) and 124(b) extending in parallel from a wider portion 126 of the first straight region 120(a) to the first curved region 122(a), e.g., Figure 1In some examples, the first curved region 122(a) can be divided into two corresponding legs 128(a) and 128(b), which are connected to the legs 124(a) and 124(b), respectively. In some embodiments, the wider portion 126 of the first straight region 120(a) can provide fan-out space for electrical signal traces (not shown) directed from the movable end portion 116 to the fixed end portion 114(a) and / or the fixed end portion 114(b). For example, one or more electrical signal traces may be directed along the following path: from the movable end portion 116 to the wider portion 126 of the first straight region 120(a), from the wider portion 126 of the first straight region 120(a) to the leg 124(a), from the leg 124(a) to the corresponding leg 128(a) of the first curved region 122(a), from the corresponding leg 128(a) to the second straight region 120(b) along the first direction to the second curved region 122(b) (e.g., through a section of the second straight region 120(b) extending from its connection with the first curved region 122(a) to its connection with the second curved region 122(b)), and from the second curved region 122(b) to the fixed end portion 114(a). Additionally or alternatively, one or more electrical signal traces may be directed along the following path: from the movable end portion 116 to the wider portion 126 of the first straight region 120(a), from the wider portion 126 of the first straight region 120(a) to the leg 124(b), from the leg 124(b) to the corresponding leg 128(b) of the first curved region 122(a), from the corresponding leg 128(b) to the second straight region 120(b) along a second direction (opposite to the first direction) to the third curved region 122(c) (e.g., through another section of the second straight region 120(b) extending from its connection to the first curved region 122(a) to its connection to the third curved region 122(c), and from the third curved region 122(c) to the fixed end portion 114(b).

[0036] In some embodiments, the number, type, size, and / or arrangement of electrical signal traces routed via leg 124(a) may be the same as or different from the number, type, size, and / or arrangement of electrical signal traces routed via leg 124(b). In various non-limiting examples, electrical signal traces and / or dummy traces (e.g., elements that do not actually carry electrical signals) may be distributed between leg 124(a) and leg 124(b) such that, for example, weight symmetry is maintained about a plane that defines geometric symmetry of dynamic flexible circuit 102.

[0037] According to some embodiments, a portion of the wider portion 126 can be used to provide a surface area for attaching the movable end portion 116 to one or more components (e.g., to a substrate via an adhesive), such as to couple the dynamic flex circuit 102 with the image sensor 106. Additionally or alternatively, the movable end portion 116 can provide a surface area for the same (or similar) attachment. In some non-limiting examples, the movable end portion 116 can wrap around a peripheral edge portion of a substrate and / or another component coupled to the image sensor 106.

[0038] As discussed above, the camera 100 may include an actuator 108 and / or a suspension arrangement 112. In some non-limiting examples, the actuator may include a voice coil motor (VCM) actuator. The VCM actuator may include one or more magnets and one or more coils. The magnets and coils may magnetically interact to generate a Lorentz force that moves the image sensor 106, for example, to provide AF and / or OIS functionality. However, the actuator 108 may include any other actuator suitable for moving the image sensor 106. In various embodiments, the suspension arrangement 112 may be configured to suspend the image sensor 106 from one or more stationary structures (e.g., Figure 2 In addition, the suspension arrangement 112 may be configured to allow the image sensor 106 to move, for example, in accordance with the movement caused by the actuator 108. In some non-limiting examples, the suspension arrangement 112 may include one or more flexures (e.g., leaf springs, suspension wires, flexure arms, etc.) and / or bearings (e.g., ball bearings), etc.

[0039] According to some embodiments, the optical element 110 may include a lens group. For example, the lens group may include one or more lens elements that define an optical axis. In some embodiments, the optical element 100 may additionally or alternatively include one or more light folding elements (e.g., prisms, mirrors, etc.) configured to fold the light path before the light reaches the image sensor 106. As such, the camera 100 may be considered to have a folded optics arrangement that folds the light path in one or more circumstances before reaching the image sensor 106. In some embodiments, the folded optics arrangement may provide space in certain locations that enables space to efficiently include the dynamic flexible circuit 102. As a non-limiting example, at least a portion of the intermediate portion 118 may be disposed in a space below the light folding element and / or below the lens group without increasing the Z-axis dimension of the camera 100. In some embodiments, the camera 100 may not include a light folding element.

[0040] As discussed above, in some examples, the actuator 108 can be configured to move one or more of the optical elements 110 relative to the image sensor 106. Further, the actuator 108 can be configured to move the image sensor 106 relative to the optical elements 110. In a non-limiting example, the optical elements 110 can include a lens group and one or more light folding elements. The actuator 108 can be configured to move the lens group and / or the light folding element relative to the image sensor 106, for example, to provide AF functionality. Further, the actuator 108 can be configured to move the image sensor 106 relative to the optical elements 110, for example, to provide OIS functionality. According to some non-limiting examples, the number of curved areas and / or straight areas of the dynamic flex circuit 102 can be reduced in embodiments where the number of axes of movement of the image sensor 106 is reduced, for example, by having the actuator 108 move one or more optical elements 110 relative to the image sensor 106 to achieve AF and / or OIS in addition to having the actuator 108 move the image sensor 106 to achieve AF and / or OIS.

[0041] Figure 2 A perspective view of a portion of an exemplary camera 200 is shown that includes a dynamic flexible circuit 202 that can be used with a movable image sensor 204. In some embodiments, aspects of the camera 200 can be similar to those described herein with reference to Figure 1 In some embodiments, aspects of the dynamic flexible circuit 202 may be the same as (or similar to) those described herein. Figure 1 and Figures 3 to 6 One or more aspects of the dynamic flexible circuits described herein are the same (or similar). To simplify the discussion, the description used to describe Figure 1 The terminology of the portions of the dynamic flexible circuit 100 will be used herein to refer to Figure 2 portion of a dynamic flexible circuit 200 .

[0042] According to some embodiments, camera 200 may include dynamic flexible circuit 202, image sensor 204, substrate 206, and one or more stationary structures (e.g., stationary structure 208, base structure 210, etc.). Image sensor 204 may be attached to substrate 206 and / or one or more other components, such as a movable platform of a suspension arrangement of camera 200.

[0043] In some embodiments, the dynamic flexible circuit 202 may include fixed end portions 114 (a) and 114 (b), a middle portion 118, and a movable end portion 116 (connected by Figure 2The fixed end portions 114(a) and 114(b) may be attached to the stationary structure 208. In some embodiments, the stationary structure 208 may include a Figure 1 Additionally or alternatively, the stationary structure 208 can provide an electrical connection between the stationary flexible circuit 104 and each of the fixed end portions 114(a) and 114(b) of the dynamic flexible circuit 202. In some embodiments, the movable end portion 116 can be attached to the substrate 206 and / or otherwise coupled to the image sensor 204.

In some embodiments, the one or more orientation sensors 768 include any combination of orientation / rotation sensors. Figure 7 One or more orientation sensors 768 are shown coupled to the peripherals interface 718. Alternatively, the one or more orientation sensors 768 can be coupled to the input controller 760 in the I / O subsystem 706.

In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector.

[0079] The contact / motion module 730 can detect contact with the touch screen 712 (in conjunction with the display controller 756) and other touch-sensitive devices (e.g., a touchpad or physical click wheel). The contact / motion module 730 includes various software components for performing various operations related to the detection of contact, such as determining whether contact has occurred (e.g., detecting a finger press event), determining whether there is movement of the contact and tracking the movement on the touch-sensitive surface (e.g., detecting one or more finger drag events), and determining whether the contact has terminated (e.g., detecting a finger lift event or contact interruption). The contact / motion module 730 receives contact data from the touch-sensitive surface. Determining the movement of a contact point represented by a series of contact data may include determining the rate (magnitude), velocity (magnitude and direction), and / or acceleration (change in magnitude and / or direction) of the contact point. These operations can be applied to a single contact point (e.g., a finger contact point) or multiple simultaneous contacts (e.g., "multi-touch" / multiple finger contacts). In some embodiments, the contact / motion module 730 and the display controller 756 detect contact on a touchpad.

[0080] The contact / motion module 730 can detect gesture inputs made by a user. Different gestures on a touch-sensitive surface have different contact patterns. Therefore, a gesture can be detected by detecting a specific contact pattern. For example, detecting a single-finger tap gesture includes detecting a finger press event, and then detecting a finger lift (lift-off) event at the same location (or substantially the same location) as the finger press event (e.g., at an icon location). For another example, detecting a finger swipe gesture on a touch-sensitive surface includes detecting a finger press event, then detecting one or more finger drag events, and then detecting a finger lift (lift-off) event.
