Description

Technology Field

[0001] Various embodiments of the present invention relate to an electronic device having a sliding structure. Background Technology

[0002] The electronic device may have a slider (or roller) structure. For example, the electronic device may include a housing, a slider portion, a roller that allows a part of the slider portion to be drawn into or drawn out of the housing, and a flexible display. Depending on the degree of sliding of the slider portion, a variation in the performance of the antenna provided in the electronic device may occur. For example, the intensity of electromagnetic waves radiated from the antenna may vary depending on the degree of sliding. The problem to be solved

[0003] The capacitance value calculated using data received from the grip sensor may include an internal capacitance component value existing within the electronic device itself when there is no dielectric near the electronic device, and an external capacitance component value due to a dielectric adjacent to the electronic device (e.g., the human body). Here, the internal capacitance component value may vary depending on the relative distance and / or overlapping area between the grip sensor and the housing.

[0004] Therefore, it may be necessary to have an internal capacitance component value defined differently depending on the degree to which the slider part is retracted into the housing. Otherwise, if a fixed internal capacitance component value is used regardless of the state, unnecessary power back-off operations may be performed, leading to degradation of radiation performance, or the power back-off operation may not be performed when it is actually needed, potentially causing adverse effects on the human body. The threshold used to determine whether the power back-off operation is performed may also vary depending on the degree to which the slider part is retracted into the housing.

[0005] In various embodiments, the electronic device can perform a power back-off operation at the time actually needed by redefining the internal capacitance component value and threshold when the state of the electronic device changes.

The memory connected to the processor can store instructions such that, when executed, the processor: controls the roller driving circuit to change the state of the slider part from a first state to a second state in which it is retracted further into the housing or withdrawn further from the housing in response to user input; corrects the capacitance value measured through the first grip sensor to a correction value using an offset value corresponding to the second state; and, when the correction value is greater than or equal to a threshold value corresponding to the second state, performs a power back-off operation to lower the power of the RF signal to be output to the first antenna in the wireless communication circuit using a power back-off value corresponding to the second state.

[0041] In the following, for convenience of explanation, the side of the display that is visually exposed to the user may be referred to as the front of the electronic device (101). The side opposite the front may be referred to as the rear of the electronic device (101). Additionally, the side surrounding the space between the front and the rear may be referred to as the side of the electronic device (101). The term “state” may refer to the structural form, posture, shape, or form of the electronic device (101) (or the display, slider part, or housing constituting the electronic device (101)).

[0042] Various sliding structures may be applied to the electronic device (101). For example, the electronic device (101) may include a housing, a slider part, a roller that allows the slider part to be retracted into the housing and the slider part to be withdrawn from the housing, and a flexible display. The slider part may be divided into a part that can be retracted into the housing (hereinafter, retracted part) and a part that remains exposed to the outside. When the retracted part of the slider part is fully withdrawn from the housing (e.g., open state, extended state, slide-out state), the entire display (or most of the display area) may be exposed to the outside through the front. As the retracted part of the slider part is retracted into the housing, the display may also be retracted into the housing. The display may also be divided into a part that remains exposed to the outside (e.g., first display area, first section) and a part that can be retracted into the housing (e.g., second display area, second section, bendable section). When the entire inlet portion of the slider part is switched to a state in which it is retracted into the housing (e.g., closed state, reduced state, slide-in state), the entire second display area of ​​the display may be retracted into the housing. As another example, when switching from an expanded state to a reduced state, a part of the display (e.g., the second display area) may not be retracted into the housing but may be moved and positioned toward the rear via the side. As exemplified above, the electronic device (101) may have a sliding structure in which a part of the display is retracted into the housing, or a sliding structure in which a part of the display is moved and positioned from the front to the rear. In the display, only the part exposed through the front may be determined as the active area for displaying visual information.Parts that are recessed into the housing or moved to the rear can be determined as inactive areas.

[0044] Referring to FIGS. 2a, FIGS. 2b, FIGS. 3a, and FIGS. 3b, an electronic device (200) (e.g., the electronic device (101) of FIG. 1) may be implemented to allow the screen (2301) to be extended in a sliding manner. For example, the screen (2301) may be an area of ​​the flexible display (230) that is visible to the outside. FIGS. 2a and FIGS. 2b illustrate an electronic device (200) in a state where the screen (2301) is not extended, and FIGS. 3a and FIGS. 3b illustrate an electronic device (200) in a state where the screen (2301) is extended. The state where the screen (2301) is not extended is a state in which the slider part (or sliding plate) (220) for the sliding motion of the display (230) is not slid out, and may be referred to as the 'closed state' below. The expanded state of the screen (2301) is a maximally expanded state in which the screen (2301) is no longer expanded by the slide-out of the slider part (220), and may be referred to as the 'open state' below. For example, the slide-out may be the slider part (220) moving at least partially in a first direction (e.g., +x axis direction) when the electronic device (200) is switched from a closed state to an open state. According to various embodiments, the open state may be defined as a state in which the screen (2301) is expanded compared to a closed state, and may provide a screen of various sizes depending on the movement position of the slider part (220). According to various embodiments, an intermediated state (or free stop state) may refer to a state between the closed state of FIG. 2a and the open state of FIG. 3a. The screen (2301) may include an active area of ​​a display (230) that is visually exposed and capable of outputting an image, and the electronic device (200) may adjust the active area according to the movement of the slider part (220) or the movement of the display (230).In the following description, the open state may refer to a state in which the screen (2301) is maximally expanded. In some embodiments, a display (230) that is slidably positioned in the electronic device (200) of FIG. 2a to provide the screen (2301) may be referred to as a 'slide-out display' or an 'expandable display'.

[0045] According to one embodiment, the electronic device (200) may include a sliding structure associated with a display (230). For example, when the display (230) is moved by an external force to a set distance, due to the elastic structure included in the sliding structure, it may be switched from a closed state to an open state or from an open state to a closed state without further external force (e.g., semi-automatic slide operation).

[0046] According to some embodiments, when a signal is generated through an input device included in the electronic device (200), the electronic device (200) may be switched from a closed state to an open state, or from an open state to a closed state, due to a driving circuit such as a motor connected to the display (230). For example, when a signal is generated through a hardware button, or a software button provided through the screen (2301), the electronic device (200) may be switched from a closed state to an open state, or from an open state to a closed state.

[0047] According to various embodiments, when a signal is generated from various sensors, such as a pressure sensor, the electronic device (200) may be switched from a closed state to an open state, or from an open state to a closed state. For example, when the electronic device (200) is held or grasped by hand, a squeeze gesture in which a part of the hand (e.g., palm or fingers) presses within a designated section of the electronic device (200) may be detected by the sensor, and in response, the electronic device (200) may be switched from a closed state to an open state, or from an open state to a closed state.

[0048] According to one embodiment, the display (230) may include a second section (②) (see FIG. 3a). The second section (②) may include an extended portion of the screen (2301) when the electronic device (200) is switched from a closed state to an open state. When the electronic device (200) is switched from a closed state to an open state, the second section (②) is slid out from the internal space of the electronic device (200), thereby expanding the screen (2301). When the electronic device (200) is switched from an open state to a closed state, at least a portion of the second section (②) is slid into the internal space of the electronic device (200), thereby shrinking the screen (2301). When the electronic device (200) is switched from an open state to a closed state, at least a portion of the second section (②) may be bent and moved into the internal space of the electronic device (200). For example, the display (230) may include a flexible substrate (e.g., a plastic substrate) formed from a polymer material including polyimide (PI) or polyester (PET). The second section (②) is a part of the display (230) that bends when the electronic device (200) switches between an open state and a closed state, and may be referred to, for example, as a bendable section. In the following description, the second section (②) is referred to as a bendable section.

[0049] According to one embodiment, the electronic device (200) may include a housing (210), a slider part (220), or a display (230).

[0050] The housing (or case) (210) may include, for example, a back cover (212), a first side cover (213), or a second side cover (214). The back cover (212), the first side cover (213), or the second side cover (214) may be connected to a support member (not shown) located inside the electronic device (200) and may form at least a part of the exterior of the electronic device (200).

[0051] The back cover (212) may, for example, form at least a portion of the rear surface (200B) of the electronic device (200). In one embodiment, the back cover (212) may be substantially opaque. For example, the back cover (212) may be formed by coated or colored glass, ceramic, polymer, metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two of the above materials. According to some embodiments, when the bendable section (②) of the display (230) is retracted into the internal space of the housing (210) (e.g., closed), at least a portion of the bendable section (②) may be positioned so that it is visible from the outside through the back cover (212). In this case, the back cover (212) may be formed of a transparent material and / or a translucent material.

[0052] According to one embodiment, the back cover (212) may include a flat portion (212a) and curved portions (212b, 212c) located opposite each other with the flat portion (212a) in between. The curved portions (212b, 212c) are formed adjacent to each of the relatively long edges (not shown) on both sides of the back cover (212) and may be curved and seamlessly extended toward a screen located opposite the back cover (212). According to some embodiments, the back cover (212) may include one of the curved portions (212b, 212c) or may be implemented without the curved portions (212b, 212c).

[0053] According to one embodiment, the first side cover (213) and the second side cover (214) may be positioned opposite each other with the display (230) in between in a second direction (e.g., y-axis direction) that is orthogonal to the first direction (e.g., +x-axis direction) of the slide-out of the slider portion (220). The first side cover (213) may form at least a portion of the first side (or, upper side) (213a) of the electronic device (200), and the second side cover (214) may form at least a portion of the second side (or, lower side) (214a) of the electronic device (200) facing in the opposite direction to the first side (213a). The first side cover (213) may include a first edge portion (or, first rim) (213b) extending from the edge of the first side (213a). For example, the first edge portion (213b) may form at least a part of the bezel on one side of the electronic device (200). The second side cover (214) may include a second edge portion (or, second rim) (214b) extending from the edge of the second side (214a). For example, the second edge portion (214b) may form at least a part of the bezel on the other side of the electronic device (200). According to one embodiment, in the closed state of FIG. 2a, the surface of the first edge portion (213b), the surface of the second edge portion (214b), and the surface of the slider portion (220) are smoothly connected to form a curved portion (not shown) on one side corresponding to the first curved portion (230b) of the screen (2301). According to various embodiments, the surface of the first edge portion (213b) or the surface of the second edge portion (214b) may include a side curved portion (not shown) corresponding to the second curved portion (230c) of the screen (2301) located on the opposite side from the first curved portion (230b).

[0054] According to one embodiment, the slider portion (220) may slide on a support member (not shown) located inside the electronic device (200). At least a portion of the display (230) may be placed on the slider portion (220), and the closed state of FIG. 2a or the open state of FIG. 3a may be formed based on the position of the slider portion (220) on the support member. The slider portion (220) serves to support at least a portion of the display (230) and may be referred to as a display support structure in some embodiments.

[0055] According to one embodiment, the slider portion (220) may include a third edge portion (220b) that forms at least a portion of the outer surface of the electronic device (200) (e.g., a surface exposed to the outside to form the exterior of the electronic device (200)). For example, the third edge portion (220b) may form a bezel around the screen together with the first edge portion (213b) and the second edge portion (214b) in the closed state of FIG. 2a. The third edge portion (220b) may extend in a second direction (e.g., the y-axis direction) to connect one end of the first side cover (213) and one end of the second side cover (214) in the closed state. For example, in the closed state of FIG. 2a, the surface of the third edge portion (220b) can be smoothly connected to the surface of the first edge portion (213b) and / or the surface of the second edge portion (214b).

[0056] According to one embodiment, due to the slide-out of the slider portion (220), at least a portion of the bendable section (②) comes out from inside the electronic device (200), and the screen (2301) can be provided in an extended state (e.g., open state) as in FIG. 3a.

[0057] According to one embodiment, in the closed state of FIG. 2a, the screen (2301) may include a flat section (230a) and a first curved section (230b) and / or a second curved section (230c) located opposite each other with the flat section (230a) in between. For example, the first curved section (230b) and the second curved section (230c) may be substantially symmetrical with respect to the flat section (230a). When transitioning from the closed state of FIG. 2a to the open state of FIG. 3a, the flat section (230a) may be extended. For example, a portion of the bendable section (②) forming the second curved section (230c) in the closed state of FIG. 2a may be included in the extended flat section (230a) when transitioning from the closed state of FIG. 2a to the open state of FIG. 3a, and may be formed as another portion of the bendable section (②).

[0058] According to one embodiment, the electronic device (200) may include an opening (not shown) for inserting or withdrawing a bendable section (②), and / or a pulley (not shown) located at the opening. The pulley may be positioned corresponding to the bendable section (②), and the movement of the bendable section (②) and the direction of movement thereof may be guided through the rotation of the pulley in the transition between the closed state of FIG. 2a and the open state of FIG. 3a. The first curved surface (230b) may be formed corresponding to a curved surface formed on one side of the slider section (220). The second curved surface (230c) may be formed by a portion of the bendable section (②) corresponding to the curved surface of the pulley. The first curved surface (230b) may be positioned on the opposite side of the second curved surface (230c) in the closed or open state of the electronic device (200) to improve the aesthetics of the screen (2301). According to some embodiments, the planar portion (230a) may be implemented in an extended form without the first curved portion (230b).

[0059] According to one embodiment, the electronic device (200) may include a microphone hole (251) (e.g., input module (150) of FIG. 1), a speaker hole (252) (e.g., acoustic output module (155) of FIG. 1), a connector hole (253) (e.g., connection terminal (178) of FIG. 1), a camera module (254) (e.g., camera module (180) of FIG. 1), or a flash (255). The holes (251, 252, 253) may be formed on a second side (214a). The camera module (254) and the flash (255) may be placed on, for example, the rear (200B) of the electronic device (200). According to various embodiments, the flash (255) may be implemented by being included in the camera module (254). In some embodiments, the electronic device (200) may omit at least one of the components or additionally include other components.

[0060] According to various embodiments, the electronic device (200) may include a sensor module (e.g., the sensor module (176) of FIG. 1). For example, the sensor module may include at least one of a gesture sensor, a gyroscope sensor, a barometric pressure sensor, a magnetic sensor, an accelerometer sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biosensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0061] FIG. 4 is an exploded perspective view of the electronic device (200) of FIG. 2a according to one embodiment. Referring to FIG. 4, in one embodiment, the electronic device (200) may include a back cover (212), a first side cover (213), a second side cover (214), a main part (400), a pulley (460), a slider part (220), a display (230), a support sheet (470), or a multi-bar structure (or a multi-bar assembly) (480). The main part (400) may include a support member assembly (401) or a printed circuit board (490) (e.g., a printed circuit board (PCB), a flexible PCB (FPCB), or a rigid-flexible PCB (RFPCB)). In describing FIG. 4 below, parts that overlap with the description of FIG. 2a to FIG. 3b may be omitted or briefly described.

[0062] According to one embodiment, a support member assembly (or, support structure) (401) may contribute to the durability or rigidity of an electronic device (200) as a load-bearing frame structure. At least a portion of the support member assembly (401) may include a non-metallic material (e.g., a polymer) or a metallic material. A housing (210) (see FIG. 2a) including a back cover (212), a first side cover (213), or a second side cover (214), a pulley (460), a slider part (220), a display (230), a support sheet (470), a multi-bar structure (480), or a printed circuit board (490) may be placed or coupled to the support member assembly (401).

[0063] According to one embodiment, the support member assembly (401) may include a first support member (410), a second support member (420), a third support member (430), a fourth support member (440), or a fifth support member (450).

[0064] The first support member (or first bracket) (410) may be in the form of a plate, for example. A slider portion (220) may be disposed on one side (410a) of the first support member (410). The second support member (or second bracket) (420) may be in the form of a plate that overlaps at least a portion of the first support member (410) when viewed in the z-axis direction, for example, or may be coupled with the first support member (410) and / or the third support member (430). The second support member (420) may be positioned between the first support member (410) and the third support member (430). The third support member (430) may be coupled with the first support member (410) and / or the second support member (420) with the second support member (420) in between. A printed circuit board (490) may be placed on the second support member (420) between the first support member (410) and the second support member (420). A fourth support member (440) may be attached to one side of an assembly (or structure) (not shown) in which the first support member (410), the second support member (420), and the third support member (430) are combined. A fifth support member (450) may be attached to the other side of an assembly (or structure) (not shown) in which the first support member (410), the second support member (420), and the third support member (430) are combined, and may be located on the opposite side from the fourth support member (440). A first side cover (213) may be attached to the support member assembly (401) on the side of the fourth support member (440). The second side cover (214) can be coupled to the support member assembly (401) on the side of the fifth support member (450). The back cover (212) can be coupled to the support member assembly (401) on the side of the third support member (430).

[0065] According to various embodiments, at least two of the first support member (410), the second support member (420), the third support member (430), the fourth support member (440), and the fifth support member (450) may be implemented integrally. According to some embodiments, the support member assembly (401) may refer to a structure that forms at least some of the first support member (410), the second support member (420), the third support member (430), the fourth support member (440), and the fifth support member (450). According to some embodiments, some of the first support member (410), the second support member (420), the third support member (430), the fourth support member (440), and the fifth support member (450) may be omitted.

[0066] The first support member (410) may include, for example, a first side (not shown) facing the fourth support member (440), a second side (410c) facing the fifth support member (450) and located opposite the first side, a third side (or right side) (not shown) connecting one end of the first side and one end of the second side (410c), or a fourth side (or left side) (410d) connecting the other end of the first side and the other end of the second side (410c) and located opposite the third side. According to one embodiment, the pulley (460) may be located near the third side of the first support member (410). As another example, in the case of an electronic device formed with the opposite sliding direction, the pulley (460) may be located near the fourth side (410d) of the first support member (410). The pulley (460) may include a cylindrical roller (461) extending in a direction (e.g., +y axis direction) from the fifth support member (450) toward the fourth support member (440). The pulley (460) may include a first rotation shaft (not shown) and a second rotation shaft (463) connected to the roller (461), and the first rotation shaft and the second rotation shaft (463) may be located on opposite sides of each other with the roller (461) in between. The first rotation shaft may be located between the roller (461) and the first side cover (213) and may be connected to the fourth support member (440). The second rotation shaft (463) may be located between the roller (461) and the second side cover (214) and may be connected to the fifth support member (450). The fourth support member (440) may include a first through hole (441) into which a first rotation axis is inserted, and the fifth support member (450) may include a second through hole (451) into which a second rotation axis (463) is inserted. The roller (461) may be able to rotate based on the first rotation axis disposed in the fourth support member (440) and the second rotation axis (463) disposed in the fifth support member (450).

[0067] According to one embodiment, the slider portion (220) may be disposed in the support member assembly (401) so as to be slidably movable on the first support member (410). For example, a sliding structure may be provided between the first support member (410) and the slider portion (220) to support and guide the connection between them and the movement of the slider portion (220). According to one embodiment, the sliding structure may include at least one elastic structure (406). When the slider portion (220) is moved to a set distance by an external force, it may be switched from the closed state of FIG. 2a to the open state of FIG. 3a, or from the open state to the closed state, without further external force due to the at least one elastic structure (406). The at least one elastic structure (406) may include various elastic members, such as, for example, a torsion spring. For example, as an elastic structure (406), the torsion spring may include one end connected to the slider part (220), the other end connected to the first support member (410), and a spring part between the one end and the other end. When the slider part (220) is moved by an external force to a distance set in the first direction of slide-out (e.g., the +x axis direction), the position of the one end relative to the other end is changed so that the slider part (220) can be moved in the first direction due to the elasticity of the spring part without further external force, and thus can be switched from the closed state of FIG. 2a to the open state of FIG. 3a. When the slider part (220) is moved by an external force to a distance set in a second direction opposite to the first direction (e.g., -x axis direction), the position of the first part relative to the other end is changed, and the slider part (220) can be moved in the second direction due to the elasticity of the spring part without any further external force, and thus can be switched from the open state of FIG. 3a to the closed state of FIG. 2a.

[0068] According to various embodiments, a portion of the support member assembly (401) in the main part (400) may be composed of a conductor (e.g., a metallic material). For example, a portion of the fifth support member (450) and / or a portion adjacent to the fifth support member (450) in the first support member (410) may be composed of a conductor. Such a conductor may be used as an antenna for a wireless communication circuit to communicate with an external electronic device via a wireless communication network (e.g., a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). Additionally, the conductor may be electrically connected to a first grip sensor (not shown). For example, the first grip sensor may be mounted on the main part (400) (e.g., a printed circuit board (490)) adjacent to the conductor. The processor can measure the capacitance formed between the conductor and ground (e.g., ground of the printed circuit board (490)) through the first grip sensor and, based on the capacitance value, determine whether to perform a power back-off operation to lower the power of the RF signal to be output to the antenna.

[0069] The processor can recognize from the first grip sensor that a dielectric (e.g., finger, palm, face) is adjacent to the electronic device (200) through a conductor formed in the main part (400). The first grip sensor may be electrically isolated from the slider part (220). Accordingly, a second grip sensor for recognizing that the dielectric is adjacent to the slider part (220) may be mounted on the slider part (220).

[0070] According to various embodiments, a portion of the slider portion (220) may be composed of a conductor (e.g., a metallic material). For example, the portion (221) adjacent to the fifth support member (450) in the slider portion (220) may be composed of a conductor. The conductive portion (221) may be connected to a second grip sensor (not shown). For example, the second grip sensor may be mounted on the slider portion (220) adjacent to the conductive portion (221). The processor may measure the capacitance between the conductive portion (221) and ground (e.g., ground of the printed circuit board (490)) through the second grip sensor and, based on the capacitance value, determine whether to perform a power back-off operation to lower the power of the RF signal to be output to the antenna. Additionally, the conductive portion (221) can be used as an antenna for the wireless communication circuit to communicate with an external electronic device through a wireless communication network (e.g., legacy cellular network, 5G network, next-generation communication network, internet, or a computer network (e.g., LAN or WAN)).

[0071] According to various embodiments, the housing (210) may be defined to further include at least a portion of the support member assembly (401). For example, the housing (210) may include one side facing in a first direction (e.g., +z axis direction) (e.g., one side (410a) formed by the first support member (410)), and another side facing in a second direction (e.g., -z axis direction) opposite to the first side (410a) (e.g., rear side (200B) of FIG. 2B). The slider portion (220) may be disposed on one side of the housing (210) (e.g., one side (410a) formed by the first support member (410)) so as to be slidable in a third direction (e.g., x axis direction) perpendicular to the first direction. According to one embodiment, the display (230) may include a first section (①) extending from a bendable section (②). The first section (①) may be placed on the slider section (220). When transitioning from the closed state of FIG. 2a to the open state of FIG. 3a, the bendable section (②) connected to the first section (①) may slide outward due to the movement of the slider section (220), thereby expanding the screen (see screen (2301) of FIG. 3a). When transitioning from the open state of FIG. 2a to the closed state of FIG. 3a, the bendable section (②) may move inward at least partially into the electronic device (200) due to the movement of the slider section (220), thereby reducing the screen (see screen (2301) of FIG. 2a). The support member assembly (401) may include an opening (not shown) for the insertion or withdrawal of the bendable section (②), and a pulley (460) may be positioned in the opening. The opening includes a gap on one side between the first support member (410) and the third support member (430), and a portion (431) of the third support member (430) adjacent to the opening may be curved to correspond to the curved surface of the roller (461). The pulley (460) may be positioned corresponding to the bendable section (②), and the pulley (460) may be rotated by moving the bendable section (②) in the transition between the closed state of FIG. 2a and the open state of FIG. 3a.

[0072] According to one embodiment, the state of the electronic device (200) may be defined based on the rotation angle of the roller (461) (e.g., the angle at which the roller rotates in the direction in which the display (230) is released from the roller (e.g., clockwise). For example, if the rotation angle of the roller exceeds a first threshold value, the state of the electronic device (200) may be defined as a first state (e.g., closed state, normal state, reduced state, slide-in state) in which only the first section (①) of the display (230) is exposed (or, the bendable section (②) is placed in the internal space). If the rotation angle of the roller exceeds a second threshold value greater than the first threshold value, the state of the electronic device (200) may be defined as a second state (e.g., open state, extended state, slide-out state) in which the entire display (230) (e.g., the first section (①) and the bendable section (②)) is exposed. The bendable section (②) may be maintained in a partially exposed (or partially hidden) state (e.g., intermediate state).

[0073] According to one embodiment, the state of the electronic device (200) may be defined based on the curvature (degree of bending) of a designated area in the display (230). For example, if the curvature of the bendable section (②) corresponds to a value (or range) indicating concave (or convex), the state of the electronic device (200) may be defined as a first state. If the curvature of the bendable section (②) corresponds to a value (or range) indicating flat, the state of the electronic device (200) may be defined as a second state.

[0074] According to one embodiment, a support sheet (470) may be attached to the back surface of the display (230). The back surface of the display (230) may refer to a surface located opposite to the side from which light is emitted from a display panel containing a plurality of pixels. The support sheet (470) may contribute to the durability of the display (230). The support sheet (470) may reduce the impact of load or stress on the display (230) that may occur during the transition between the closed state of FIG. 2a and the open state of FIG. 3a. The support sheet (470) may prevent the display (230) from being damaged by the force transmitted from the slider part (220) when it is moved.

[0075] The support sheet (470) may be formed from various metallic materials and / or non-metallic materials (e.g., polymers). According to one embodiment, the support sheet (470) may comprise stainless steel. According to some embodiment, the support sheet (470) may comprise engineering plastic. According to some embodiment, the support sheet (470) may be integrally formed with the display (230). According to one embodiment, the support sheet (470) may comprise a lattice structure (not shown) that is at least partially superimposed with a portion of the display (230) where it is bent (e.g., the bendable section (②) of FIG. 3a or 4, the first curved section (230b) of FIG. 2a or 3a). The lattice structure may comprise a plurality of openings or a plurality of slits and may contribute to the bendability of the display (230). According to various embodiments, the support sheet (470) may include a recess pattern (not shown) comprising a plurality of recesses, replacing the grid structure, and the recess pattern may contribute to the flexibility of the display (230). According to various embodiments, the grid structure or the recess pattern may extend to at least a portion of the planar portion (230a) of FIG. 2a or 3a. According to various embodiments, the support sheet (470) including the grid structure or the recess pattern, or the corresponding conductive member, may be formed in a plurality of layers.

[0076] According to one embodiment, the multi-bar structure (480) may be connected to the slider portion (220) and may include a first surface (481) facing the support sheet (470) and a second surface (482) located opposite to the first surface (481). When the slider portion (220) moves, the movement and direction of the multi-bar structure (480) may be guided by a roller (461) that rotates in friction with the second surface (482). According to one embodiment, the second surface (482) may include a shape in which a plurality of bars (not shown) are arranged extending in a direction (e.g., +y axis direction) from the second rotation axis (463) of the pulley (460) toward the first rotation axis (not shown). The multi-bar structure (480) may be bent at portions having a relatively thin thickness between the plurality of bars. In various embodiments, this multi-bar structure (480) may be referred to by other terms such as 'flexible track' or 'hinge rail'.

[0077] According to one embodiment, in the closed state of FIG. 2a or the open state of FIG. 3a, at least a portion of the multi-bar structure (480) is positioned to overlap with the screen (2301) (see FIG. 2a or 3a) and can support the bendable section (②) so that the bendable section (②) of the display (230) is maintained in a form that is smoothly connected to the first section (①) of the display (230) without lifting. The multi-bar structure (480) can contribute to the movement of the bendable section (②) while maintaining a form that is smoothly connected to the first section (①) during the transition between the closed state of FIG. 2a and the open state of FIG. 3a.

[0078] According to one embodiment, a printed circuit board (490) in the main part (400) may be equipped with a processor (e.g., processor (120) of FIG. 1), memory (e.g., memory (130) of FIG. 1), interface (e.g., interface (177) of FIG. 1), communication module (e.g., communication module (190) of FIG. 1), or antenna module (e.g., antenna module (197) of FIG. 1).

[0079] The electronic device (200) may include various other elements that are placed on or electrically connected to the printed circuit board (490). For example, the electronic device (200) may include a battery (not shown) located between the first support member (410) and the second support member (420), or between the second support member (420) and the back cover (212). According to one embodiment, the electronic device (200) may include an antenna (not shown) located between the first support member (410) and the second support member (420), or between the second support member (420) and the back cover (212). The antenna (not shown) may include, for example, a near field communication (NFC) antenna, a wireless charging antenna, and / or a magnetic secure transmission (MST) antenna. The antenna (not shown) may, for example, communicate near-field with an external device or wirelessly transmit and receive power required for charging. In another embodiment, the antenna structure may be formed by a part or combination thereof of the first side cover (213) and / or the second side cover (214).

[0080] According to one embodiment, the electronic device (200) may include a flexible printed circuit board (FPCB) (237) that electrically connects a display (230) and a printed circuit board (490). For example, the flexible printed circuit board (237) may be electrically connected to the printed circuit board (490) through an opening (not shown) formed in a slider portion (220) and an opening (not shown) formed in a first support member (410).

[0081] FIGS. 5A and 5B are schematic drawings showing the lower side (214a) of the electronic device (200) in a closed state of FIG. 2A. FIG. 6 is a schematic drawing showing the lower side (214a) of the electronic device (200) in an open state of FIG. 3A.

[0082] Referring to FIGS. 5a, 5b, and 6, the electronic device (200) may include a back cover (212), a display (230), a first conductive member (510) formed as part of the main part (400), a second conductive member (520) separated from the first conductive member (510) and formed as another part of the main part (400), or a third conductive member (530) formed as part of the slider part (220) (e.g., the conductive part (221) of FIG. 4). In describing FIGS. 5a, 5b, and 6 below, parts that overlap with the description of FIGS. 2a through 4 may be omitted or briefly described.

[0083] According to one embodiment, the first conductor (510) and the second conductor (520) can each be used as antennas for a wireless communication circuit to communicate with an external electronic device through a wireless communication network. The first conductor (510) can be electrically connected to a first grip sensor (not shown). The first grip sensor can be mounted on a main part (400) (e.g., a printed circuit board (490)) adjacent to the first conductor (510).

[0084] According to one embodiment, the third conductor (530) may be electrically connected to a second grip sensor (not shown). The second grip sensor may be mounted on the slider portion (220) adjacent to the third conductor (530). In another embodiment, the third conductor (530) may be used to support the detection of a grip and may also be used as an antenna.

[0085] According to one embodiment, in order to secure a wide sensing area of ​​the grip, the first conductor (510) in the closed state of FIG. 5a-b and the open state of FIG. 6 may be positioned so as not to overlap with the third conductor (530) when viewed in the -z-axis direction.

[0086] According to one embodiment, in the closed state of FIG. 5a-b, at least a portion of the third conductor (530) may be positioned to overlap with at least a portion of the second conductor (520) when viewed in the -z-axis direction. When transitioning to the open state of FIG. 6, the third conductor (530) may not overlap with the second conductor (520).

[0087] According to various embodiments, not limited to the embodiments of FIG. 4, FIG. 5a-b or FIG. 6, the electronic device (200) may be implemented in such a way that when the slider part (220) slides out, a part of the display (230) (e.g., the bendable section (②)) is rolled up on a roller located inside the electronic device (200) and then unfolds as it comes out, thereby expanding the screen.

[0088] FIG. 7 illustrates configurations of an electronic device (700) according to various embodiments. Referring to FIG. 7, the electronic device (700) (e.g., the electronic device (101) of FIG. 1 or the electronic device (200) of FIG. 2a through FIG. 6) may include a display (230), a first antenna (711), a second antenna (712), a conductor (720), a first grip sensor (731), a second grip sensor (732), a wireless communication circuit (740), a state detection sensor (750), a roller driving circuit (760), a memory (770), and a processor (799).

[0089] A first antenna (711), a second antenna (712), a first grip sensor (731), a wireless communication circuit (740), a memory (770), and a processor (799) may be mounted on the main part (400). The processor (799) (e.g., the processor (120) of FIG. 1) may be electrically connected to the first grip sensor (731), the wireless communication circuit (740), and the memory (770). A conductor (720) and a second grip sensor (732) may be mounted on the slider part (220). The second grip sensor (732), a state detection sensor (750), a roller driving circuit (760), and a display (230) may be electrically connected to the processor (799) through an FPCB (701) (e.g., the FPCB (237) of FIG. 4). The first antenna (711) may include the first conductor (510) of FIGS. 5 and FIGS. 6. The second antenna (712) may include the second conductor (520). The conductor (720) mounted on the slider part (220) may include the third conductor (530).

[0090] A wireless communication circuit (740) (e.g., a wireless communication module (192) of FIG. 1) may include a communication processor (CP) (741), a radio frequency integrated circuit (RFIC) (742), and a radio frequency front end (RFFE) (743).

[0091] CP (741) can support the establishment of a communication channel in a band to be used for wireless communication with the second network (199), and network communication through the established communication channel. RFIC (742) can convert a baseband signal generated by CP (741) into a radio frequency (RF) signal used by the second network (199) during transmission. During reception, the RF signal is acquired from the second network (199) through an antenna (e.g., first antenna (711) and / or second antenna (712)) and can be preprocessed through RFFE (743). RFIC (742) can convert the preprocessed RF signal into a baseband signal so that it can be processed by CP (741).

[0092] The RFFE (743) may operate in a receiving mode or a transmitting mode based on a control signal received from a processor (e.g., CP (741)). According to one embodiment, the RFFE (743) may include, for example, a band-pass filter (BPF), a first amplifier circuit, a second amplifier circuit, and / or a switch as a configuration for processing the RF signal before transmitting it to one of the antennas (711, 712) or to the RFIC (742). For example, the band-pass filter (e.g., a surface acoustic wave (SAW) filter) may filter out an RF signal of a specified frequency band from an RF signal received from one of the antennas (711, 721) and output it to the RFIC (742). The first amplifier circuit (e.g., a low noise amplifier or a variable gain amplifier) ​​may amplify the RF signal that has passed through the BPF and output it to the RFIC (742). A second amplifier circuit (e.g., driver amplifier, and / or power amplifier) ​​can amplify an RF signal received from the RFIC (742) and output it to a BPF. In the receiving mode, the switch can connect a band-pass filter to the first amplifier circuit based on a control signal received from the CP (741). In the transmitting mode, the switch can connect a band-pass filter to the second amplifier circuit based on a control signal received from the CP (741). The RFFE (743) may further include a circuitry (e.g., a coupler) for acquiring power of the RF signal. For example, the circuitry may be located on a conductive path connecting the band-pass filter and the antenna, and may acquire power of the RF signal and output it to another circuitry (e.g., the CP (741)). In one embodiment, the CP (741) may perform a power-back-off operation based on the control of the processor (799).For example, CP (741) can control the second amplifier circuit to output an RF signal having a power value set to power back-off (e.g., maximum power value - power back-off value).

[0093] The conductor (720) can be used as a third antenna, and accordingly, a second RFFE (744) can be further provided in the electronic device (700). For example, the second RFFE (744) can be mounted on the slider part (220) and electrically connected to the RFIC (742) through the FPCB (701).

[0094] A state detection sensor (750) (e.g., sensor module (176) of FIG. 1) can generate data used to recognize the state of the slider part (220) (e.g., closed state of FIG. 2a, open state of FIG. 3a, intermediate state) and output it to the processor (799). For example, the state detection sensor (750) may include a sensor (e.g., encoder, Hall sensor) that is attached to the roller (461) and generates and outputs data corresponding to the rotation angle when the roller (461) rotates. As another example, the state detection sensor (750) may include a sensor (e.g., one or more pressure sensors) that is placed in a designated part of the display (230) (e.g., bendable section (②)) and generates data corresponding to the curvature of the part.

[0095] The roller drive circuit (760) may include a motor that rotates the roller (461). The roller drive circuit (760) may rotate the roller (461) under the control of the processor (799) to move the inlet portion of the slider portion (220) (e.g., the remainder excluding the third edge portion (220b)) into the housing (210) or pull it out from the housing (210). For example, the processor (799) may control the roller drive circuit (760) to perform a state change in response to user input for a button for state change (e.g., a button placed on the side of the electronic device (700), a button displayed on the display (230).

[0096] When a dielectric (e.g., finger, palm, face) approaches the electronic device (700), the capacitance value measured through the grip sensor may increase. The capacitance value may include an internal capacitance component value that exists within the electronic device (700) itself when there is no dielectric near the electronic device (700) (hereinafter referred to as the “offset value”) and an external capacitance component value caused by environmental factors outside the electronic device (700).

[0097] The capacitance value measured by the grip sensor (e.g., first grip sensor (731), second grip sensor (732)) can be corrected using an offset value. For example, the processor (799) can obtain an external capacitance component value by subtracting the offset value from the capacitance value. The processor (799) can obtain a difference value (hereinafter, “correction value”) (= capacitance value - offset value - reference value) as the capacitance component due to the dielectric adjacent to the electronic device (700) by subtracting the reference value from the external capacitance component value. When the dielectric is adjacent to the electronic device (700), a change may occur in which the amount of change in the capacitance value per unit time exceeds a predetermined value. The average of the external capacitance component values ​​obtained before such a change occurs may be set as the reference value.

[0098] The processor (799) can determine whether to perform a power back-off operation using a correction value. For example, if the dielectric is adjacent to the electronic device (700), the correction value may exceed a specified threshold value. In this case, the processor (799) may perform a power back-off operation. For example, the processor (799) may control the CP (741) to subtract the power of the RF signal output from the second amplification circuit (e.g., power amplifier) ​​by the power back-off value from the maximum power.

[0099] Since the grip sensors (e.g., first grip sensor (731), second grip sensor (732)) are located at different positions, the offset value and threshold can be set differently for each grip sensor. For example, the capacitance value measured using the first grip sensor (731) is corrected to a first correction value using the offset value set on the first grip sensor (731), and the first correction value can be compared with a first threshold. The capacitance value measured using the second grip sensor (732) is corrected to a second correction value using the offset value set on the second grip sensor (732), and the second correction value can be compared with a second threshold. The processor (799) can perform a power back-off operation if the first correction value exceeds the first threshold or if the second correction value exceeds the second threshold.

[0100] The processor (799) can determine the priority of the grip sensors. For example, the processor (799) may first use data received from the first grip sensor (731) in an operation to determine whether to power back off when the state of the slider part (220) changes. For example, the processor (799) may correct the capacitance value measured using the first grip sensor (731) using a first offset value, and perform a power back off operation if the first correction value exceeds a first threshold. If the first correction value is less than the first threshold, the processor (799) may correct the capacitance value measured using the second grip sensor (732) using a second offset value, and perform a power back off operation if the second correction value exceeds a second threshold. The processor (799) can recognize from the first grip sensor (731) a change in the amount of change in the capacitance value per unit time exceeding a predetermined value due to the dielectric proximity to the main part (400). Based on this recognition, the processor (799) can first use the data received from the first grip sensor (731) in an operation to determine whether to power back off. The processor (799) can recognize from the second grip sensor (732) a change in the amount of change in the capacitance value per unit time exceeding a predetermined value due to the dielectric proximity to the slider part (220). Based on this recognition, the processor (799) can first use the data received from the second grip sensor (732) in an operation to determine whether to power back off.

[0101] The memory (770) can store instructions that cause the processor (399) to perform operations to reset the offset value, threshold, and power back-off value according to the state change of the slider part (220). The operations may be described in detail below.

[0102] When the structure of the electronic device (700) is changed, the capacitance component existing within the electronic device (700) itself may change. For example, the offset value may vary depending on the state of the slider part (220). If the offset value is fixed regardless of the state change, unnecessary power back-off operations may be performed, causing radiation performance to deteriorate, or power back-off operations may not be performed when actually needed, causing adverse effects on the human body. Therefore, the offset value may be reset according to the state change. According to one embodiment, the electronic device (700) may be set to automatically reboot at a set time. When rebooting, the processor (799) may calculate the offset value using the capacitance value calculated based on data received from the grip sensor (e.g., the first grip sensor (731) or the second grip sensor (732)). The processor (799) can recognize a first state of the slider part (220) based on data received from the state detection sensor (750) and set the calculated offset value as a first offset value corresponding to the first state. The processor (799) can set a second offset value corresponding to the second state of the slider part (220) using the first offset value. For example, if the first state is a closed state, the processor (799) can set a value obtained by subtracting a specified value from the first offset value as a second offset value corresponding to the second state (e.g., a first intermediate state, a second intermediate state in which the bendable section (②) is more exposed than in the first intermediate state, or an open state). The processor (799) can set the offset value to be used when correcting the capacitance value measured through the grip sensor as the first offset value when the slider part (220) is in the first state, and reset it to the second offset value when the state changes to the second state. According to another embodiment, an offset value corresponding to each state may be stored in memory (770) in advance without the need for a calculation process every time a reboot occurs.In this way, the offset value stored in memory (770) in advance may be the average of offset values ​​obtained from multiple samples. When the state changes, the processor (799) checks the offset value corresponding to the changed state in memory (770) and can set the offset value to be used when correcting the capacitance value measured through the grip sensor to the checked offset value.

[0103] If the offset value is reset, the reference value based on the offset value can also be recalculated. For example, the processor (799) can calculate the external capacitance component values ​​using the newly changed offset value and reset the average of them to the reference value.

[0104] When the offset value is reset, the threshold value compared with the correction value may also be reset to determine whether to perform a more accurate power back-off. For example, a first threshold value corresponding to a first state and a second threshold value corresponding to a second state may be stored in memory (770) in advance. When the state of the slider part (220) changes from the first state to the second state, the processor (799) checks the second threshold value in memory (770) and can set the threshold value to be compared with the correction value as the second threshold value.

[0105] The slider portion (220) may include a metallic material (e.g., a conductor (720)) that affects the radiation performance of the antenna. Therefore, there may be a difference in the radiation performance of the antenna depending on the state of the slider portion (220). Such a difference may cause a problem where, during a power back-off operation, the power value is subtracted more or less than the value required to satisfy SAR. Therefore, the value for power back-off may be reset when the state changes. For example, a first power back-off value corresponding to a first state and a second power back-off value corresponding to a second state may be stored in memory (770) in advance. When the state of the slider portion (220) changes from the first state to the second state, the processor (799) checks the second power back-off value in memory (770) and can set the power back-off value to be used during the power back-off operation as the second power back-off value.

[0106] The memory (770) may store a table used to set offset values, thresholds, and power back-off values ​​according to the state of the slider part (220). Table 1 or Table 2 below may be stored in the memory (770). For example, if the electronic device (700) has a flexible structure that switches from a closed state to an open state or vice versa without an intermediate state, offset values ​​and thresholds may be stored in the memory (770) for each grip sensor and state as shown in Table 2. Additionally, power back-off values ​​that are commonly available for grip sensors may be stored in the memory (770) for each state. If the electronic device (700) has a structure used in an intermediate state, Table 1 may be stored in the memory (770). The numbers listed in Tables 1 and 2 are merely examples, and embodiments of the present invention are not limited to these numbers.

[0109] FIG. 8 illustrates the operations performed by a processor (799) for accurate and efficient power back-off in an electronic device having a slider structure according to one embodiment.

[0110] In operation 810, the processor (e.g., the processor (799) of FIG. 7) may recognize that the state of the slider part (220) has changed from a first state to a second state. For example, the processor (799) may recognize the state change based on data received from the state detection sensor (750). The transition from the first state to the second state may be a situation in which the slider part (220) is inserted into the housing (210) or withdrawn from the housing (210). For example, the state transition may be: 1) a transition from a closed state to an open state or an intermediate state; 2) a transition from an open state to an intermediate state or a closed state; 3) a transition from an intermediate state to an open state or a closed state; 4) a transition from an n-step intermediate state to a more open n+1-step intermediate state; or 5) a transition from an n+1-step intermediate state to a more closed n-step intermediate state.

[0111] In operation 820, the processor (799) can correct the capacitance value calculated using the grip sensor based on the change from the first state to the second state to a correction value using an offset value corresponding to the second state.

[0112] In one embodiment, the processor (799) may reset the offset value from a first offset value corresponding to a first state to a second offset value corresponding to a second state, reset the threshold from a first threshold corresponding to a first state to a second threshold corresponding to a second state, and reset the power back off value from a first power back off value corresponding to a first state to a second power back off value corresponding to a second state. The second offset value, the second threshold, and the second power back off value may each be different from the first offset value, the first threshold, and the first power back off value before being reset. Alternatively, at least one of the second offset value, the second threshold, and the second power back off value may be different from the corresponding value before being reset.

[0113] In the above operation 820, the processor (799) can obtain a correction value using a second offset value while the slider part (220) is maintained in a second state. For example, the processor (799) can calculate a capacitance value using data received from a grip sensor. The processor (799) can obtain an external capacitance component value by subtracting the second offset value from the capacitance value. The processor (799) can set the average of the external capacitance component values ​​obtained over a predetermined time period as a reference value. If the amount of change in the capacitance value per unit time exceeds a predetermined value, the processor (799) can obtain a correction value by subtracting the second offset value and the reference value from the capacitance value calculated using data received from the grip sensor.

[0114] When multiple grip sensors (e.g., first grip sensor (731), second grip sensor (732)) are mounted on the electronic device (700), an operation to reset an offset value and a threshold for each grip sensor may be performed. In one embodiment, the processor (799) may reset the offset value used to correct the capacitance value calculated using the first grip sensor (731) from a first-1 offset value corresponding to the first grip sensor (731) and the first state to a first-2 offset value corresponding to the first grip sensor (731) and the second state. The processor (799) may reset the threshold to be compared with the correction value calculated using the capacitance value of the first grip sensor (731) from a first-1 threshold corresponding to the first grip sensor (731) and the first state to a first-2 threshold corresponding to the first grip sensor (731) and the second state. The processor (799) can reset the offset value used to correct the capacitance value calculated using the second grip sensor (732) from the second-1 offset value corresponding to the second grip sensor (732) and the first state to the second-2 offset value corresponding to the second grip sensor (732) and the second state. The processor (799) can reset the threshold value to be compared with the correction value calculated using the capacitance value of the second grip sensor (732) from the second-1 threshold corresponding to the second grip sensor (732) and the first state to the second-2 threshold corresponding to the second grip sensor (732) and the second state. In the above operation 820, the processor (799) can obtain the correction value using the first-2 offset value or the second-2 offset value while the slider part (220) is maintained in the second state.

[0115] The processor (799) can use tables (e.g., Table 1, Table 2) when resetting offset values, thresholds, and power back-off values.

[0116] In operation 830, the processor (799) can perform a power back-off operation using a power back-off value (e.g., a second power back-off value) when the correction value is greater than or equal to a threshold value corresponding to a second state (e.g., a first-2 threshold, a second-2 threshold).

[0117] When multiple grip sensors (e.g., first grip sensor (731), second grip sensor (732)) are mounted on the electronic device (700), operation 830 can be performed for each grip sensor in a predetermined order (or priority). For example, the processor (799) may first use data received from the first grip sensor (731) to determine whether dielectric proximity is present. If dielectric proximity is not recognized from the data received from the first grip sensor (731), the processor (799) may determine whether dielectric proximity is present using data received from the second grip sensor (732), and if dielectric proximity is recognized through the second grip sensor (732), it may perform a power back-off operation.

[0118] In some embodiments, operations 820 and 830 may be performed by user input. For example, the processor (799) may control the roller driving circuit (760) to change the state of the slider part (220) from a first state to a second state in response to user input received from an input device (e.g., a touchscreen, a physical button) and perform operations 820 and 830.

[0119] FIG. 9 illustrates operations performed by a processor (799) for accurate and efficient power back-off in an electronic device having a slider structure according to one embodiment.

[0120] In operation 910, the processor (799) can recognize dielectric proximity through a grip sensor (e.g., a first grip sensor (731) or a second grip sensor (732)). For example, with the offset value and threshold set to a first offset value (e.g., a first-1 offset value, a second-1 offset value) and a first threshold (e.g., a first-1 threshold, a second-1 threshold) corresponding to a first state, the processor (799) obtains a first correction value by subtracting the first offset value and a reference value from the measured capacitance value using data received from the grip sensor, and if the first correction value is greater than or equal to the first threshold, the dielectric can be recognized as being in proximity to the electronic device (700). Here, the reference value may be the average of the external capacitance component values ​​obtained before dielectric proximity is recognized.

[0121] In operation 920, the processor (799) may recognize that the state of the slider part (220) has changed from a first state to a second state while dielectric proximity is recognized. Dielectric proximity and the state change may be recognized substantially simultaneously. If the state change is not recognized and only dielectric proximity is recognized, the processor (799) may skip the following operation 930 and perform a power back-off operation.

[0122] In operation 930, the processor (799) may determine whether to perform a power back-off operation based on a second offset value (e.g., first-2 offset value, second-2 offset value) and a second threshold (e.g., first-2 threshold, second-2 threshold) in response to the detection of dielectric proximity and state change. For example, the processor (799) may reset the offset value from a first offset value corresponding to the first state to a second offset value corresponding to the second state, reset the threshold from a first threshold corresponding to the first state to a second threshold corresponding to the second state, and reset the power back-off value from a first power back-off value corresponding to the first state to a second power back-off value corresponding to the second state. The processor (799) may obtain a second correction value by subtracting the second offset value and a reference value from the capacitance value calculated using data received from the grip sensor. If the second correction value is greater than or equal to the second threshold, the processor (799) can perform a power back-off operation.

[0123] When multiple grip sensors (e.g., first grip sensor (731), second grip sensor (732)) are mounted on the electronic device (700), operation 930 can be performed for each grip sensor in a predetermined order. For example, the processor (799) may first use data received from the first grip sensor (731) to determine whether to perform a power back-off operation. Even if it is determined from the data received from the first grip sensor (731) that there is no need to perform a power back-off, the processor (799) may use data received from the second grip sensor (732) to determine whether to perform a power back-off.
