[0048] refer to Figure 2 and Figure 3 In an embodiment, the electronic device 200 (eg, Figure 1 The electronic device 101, 102 or 104 in the embodiment may include a housing 201, a hinge cover 230 covering a foldable portion of the housing 201, and a flexible or foldable display 240 (hereinafter referred to as "display 240") disposed in a space formed by the housing 201. According to an embodiment, a surface on which the display 240 is disposed is defined as a front surface of the electronic device 200 (e.g., a first front surface 210a and a second front surface 220a). A surface opposite to the front surface is defined as a rear surface of the electronic device 200 (e.g., a first rear surface 210b and a second rear surface 220b). A surface surrounding a space between the front surface and the rear surface is defined as a side surface of the electronic device 200 (e.g., a first side surface 211a and a second side surface 221a).

[0049] According to an embodiment, the housing 201 may include a first housing 210, a second housing 220 rotatably or pivotally coupled to the first housing 210, a first rear cover 280, a second rear cover 290, and a hinge module (eg, Figure 4 The hinge module 202 (or "hinge structure") may provide at least one folding axis A as a rotation center of the first housing 210 and / or the second housing 220. The housing 201 of the electronic device 200 is not limited to Figure 2 and Figure 3The shapes and coupling methods shown in the figure may be implemented in other shapes or by combining and / or coupling other components. For example, in another embodiment, the first housing 210 and the first rear cover 280 may be formed integrally with each other, and the second housing 220 and the second rear cover 290 may be formed integrally with each other. According to an embodiment, the first housing 210 may be connected to a hinge module (e.g., Figure 4 The hinge module 202 of the electronic device 200 may include a first front surface 210a facing a first direction and a first rear surface 210b facing a second direction opposite to the first direction. The second housing 220 may be connected to the hinge module 202 and may include a second front surface 220a facing a third direction and a second rear surface 220b facing a fourth direction opposite to the third direction, and may be rotated from the first housing 210 around the hinge module 202. Thus, the electronic device 200 may be transformed into a folded state or an unfolded state. In the folded state of the electronic device 200, the first front surface 210a may face the second front surface 220a, and in the unfolded state, the third direction may be substantially parallel to the first direction. Hereinafter, unless otherwise specified, the directions are described based on the unfolded state of the electronic device 200. In an embodiment, the "first position" or "folded state" may refer to a state in which the first housing 210 and the second housing 220 are set to substantially face each other, and the "second position" or "unfolded state" may refer to a state in which the second housing 220 is rotated from the first position to form a specified angle with the first housing 210. In the disclosed embodiment, the second housing 220 can be rotated 180 degrees from the first position to be disposed parallel to a side of the first housing 210. In addition, the first housing 210 and the second housing 220 need not have the same size, i.e., the first housing 210 can at least partially overlap the second housing 220, or vice versa.

[0050] According to an embodiment, the first housing 210 and the second housing 220 are arranged on both sides of the folding axis A, and are symmetrical in shape relative to the folding axis A as a whole. As described below, different angles or distances may be formed between the first housing 210 and the second housing 220, depending on whether the electronic device 200 is in an unfolded state, a folded state, or an intermediate state. According to an embodiment, the second housing 220 further includes a sensor area 224, in which various sensors (e.g., a front camera) are arranged, which is different from the first housing 210, but in the remaining areas, the second housing 220 may be symmetrical in shape with the first housing 210. According to an embodiment, a plurality of (e.g., two) folding axes A parallel to each other may be arranged. In the present disclosure, the folding axis A is arranged along the length direction (Y-axis direction) of the electronic device 200, but the direction of the folding axis A is not limited thereto. For example, according to the external design or the user's usage habits, the electronic device 200 may be understood as including a folding axis A extending in the width direction (e.g., X-axis direction).

[0051] According to an embodiment, the electronic device 200 may include a structure for inserting a digital pen. For example, a hole 223 for inserting a digital pen may be formed in a side surface of the first housing 210 or a side surface of the second housing 220 of the electronic device 200.

[0052] According to an embodiment, the first housing 210 and the second housing 220 may be at least partially formed of a metal or non-metal material having a rigidity selected to support the display 240. At least a portion formed of metal may provide a ground plane for the electronic device 200 and may be connected to a printed circuit board (e.g., Figure 4 The ground conductor on the board unit 260 is electrically connected.

[0053] According to an embodiment, the sensor area 224 may be formed to have a predetermined area, adjacent to the corner of the second housing 220. However, the arrangement, shape or size of the sensor area 224 is not limited to that shown. For example, in another embodiment, the sensor area 224 may be disposed in any area between different corners or top corners and bottom corners of the second housing 220, or in the first housing 210. According to an embodiment, the components embedded in the electronic device 200 for performing various functions may be visually exposed to the front surface of the electronic device 200 through the sensor area 224 or one or more openings in the sensor area 224. In an embodiment, the components may include various types of sensors. The sensor may include, for example, at least one of a front camera, a receiver or a proximity sensor.

[0054] According to an embodiment, the first rear cover 280 may be provided on the rear surface of the electronic device 200 on one side of the folding axis A and, for example, have a substantially rectangular periphery that may be surrounded by the first housing 210. Similarly, the second rear cover 290 may be provided on the rear surface of the electronic device 200 on the opposite side of the folding axis A and its periphery may be surrounded by the second housing 220.

[0055] According to an embodiment, the first back cover 280 and the second back cover 290 may be substantially symmetrical in shape with respect to the folding axis A. However, the first back cover 280 and the second back cover 290 are not necessarily symmetrical in shape. In an embodiment, the electronic device 200 may include a first back cover 280 and a second back cover 290 having different shapes (e.g., asymmetrical shapes).

[0056] According to an embodiment, the first rear cover 280, the second rear cover 290, the first housing 210, and the second housing 220 may form a space in which various components of the electronic device 200 (e.g., a printed circuit board or a battery) may be disposed. According to an embodiment, one or more components may be arranged or visually exposed on / through the rear surface of the electronic device 200. For example, a sub-display (e.g., Figure 4 At least a portion of the sub-display 244 of the first rear cover 280 may be visually exposed through the first rear surface area 282 of the first rear cover 280. In an embodiment, one or more components or sensors may be visually exposed through the second rear surface area 292 of the second rear cover 290. In an embodiment, the sensor may include a proximity sensor and / or a camera module 206 (e.g., a rear camera).

[0057] In an embodiment, the front camera visually exposed to the front surface of the electronic device 200 through one or more openings prepared in the sensor area 224 or the camera module 206 visually exposed through the second rear surface area 292 of the second rear cover 290 may include one or more lenses, image sensors and / or image signal processors. In an embodiment, two or more lenses (infrared (IR) camera, wide-angle lens, and telephoto lens) and image sensors may be disposed on one surface of the electronic device 200.

[0058] refer to Figure 3 (or as described below Figure 4 ), the hinge cover 230 may be disposed between the first housing 210 and the second housing 220 to conceal internal components (eg, Figure 4 According to an embodiment, the hinge cover 230 may be hidden by a portion of the first housing 210 and the second housing 220 or exposed to the outside according to the state (expanded state (e.g., flat state) or folded state) of the electronic device 200. For example, in the expanded state (e.g., the state of the second position), the hinge cover 230 is substantially covered by the first housing 210 and the second housing 220, while in the folded state (e.g., the state of the first position), most of the outer surface of the hinge cover 230 may be exposed to the outside.

[0059] According to an embodiment, Figure 2 As shown, in the unfolded state of the electronic device 200, the hinge cover 230 can be hidden by the first shell 210 and the second shell 220 so as not to be exposed. However, in the unfolded state, the hinge cover 230 can also be partially visible. As another example, Figure 3As shown, in the folded state (e.g., fully folded state) of the electronic device 200, the hinge cover 230 may be exposed to the outside between the first housing 210 and the second housing 220. As another example, in the intermediate state where the first housing 210 and the second housing 220 are folded at a certain angle, the hinge cover 230 may be partially exposed to the outside between the first housing 210 and the second housing 220. However, in this case, the exposed area may be smaller than the exposed area in the fully folded state. In an embodiment, the hinge cover 230 may include a curved surface, but the present invention is not limited thereto.

[0060] According to an embodiment, the display 240 may be disposed in a space formed by the housing 201. For example, the display 240 may be placed in a groove formed by the housing 201, and may occupy most of the front surface of the electronic device 200. Therefore, the front surface of the electronic device 200 may include the display 240 and a partial area of ​​the first housing 210 adjacent to the display 240 and a partial area of ​​the second housing 220 adjacent to the display 240. The rear surface of the electronic device 200 may include a first back cover 280, a partial area of ​​the first housing 210 adjacent to the first back cover 280, a second back cover 290, and a partial area of ​​the second housing 220 adjacent to the second back cover 290.

[0061] According to an embodiment, the display 240 may refer to a display whose at least a portion can be transformed into a flat surface or a curved surface. According to an embodiment, the display 240 may include a folding area 243, a first display area 241 (eg, Figure 2 The left side of the middle folding area 243) and the second display area 242 (for example, Figure 2 on the right side of the middle folding area 203).

[0062] However, the segmentation of the display 240 is only an example, and the display 240 may be divided into a plurality of (eg, four or more, or two) regions according to the structure or function of the display 200. Figure 2 In the illustrated embodiment, the display 240 may be divided into a plurality of regions by a folding region 243 or a folding axis (axis A) extending parallel to the Y axis, but in another embodiment, the display 240 may be divided into a plurality of regions relative to another folding region (e.g., a folding region parallel to the X axis) or another folding axis (e.g., a folding axis parallel to the X axis). According to an embodiment, the display 240 may be coupled to or disposed near a touch detection circuit, a pressure sensor capable of measuring touch strength (pressure), and / or a digitizer (not shown) for detecting a magnetic field type stylus.

[0063] According to an embodiment, the first display area 241 and the second display area 242 may be symmetrical in shape as a whole with respect to the folding area 243. According to an embodiment (not shown), unlike the first display area 241, the second display area 242 may include a notch according to the presence of the sensor area 224, but the remaining portion may be symmetrical in shape with the first display area 241. In other words, the first display area 241 and the second display area 242 may include a symmetrical portion and an asymmetrical portion.

[0064] The operations of the first housing 210 and the second housing 220 and each area of ​​the display 240 are described below according to states of the electronic device 200 (eg, an unfolded state (or a flat state) and a folded state).

[0065] According to an embodiment, when the electronic device 200 is in an unfolded state (planar state) (eg, Figure 2 ), the first display area 241 and the second display area 242 may be arranged to face substantially the same direction, and the first shell 210 and the second shell 220 may be arranged to form a substantially 180-degree angle between each other. For example, in the unfolded state, the surface of the first display area 241 and the surface of the second display area 242 may be arranged to form a 180-degree angle between each other, and face the same direction (for example, the direction in which the front surface of the electronic device is facing). In an embodiment, in the unfolded state, the edge of the first shell 210 may be arranged to be adjacent to the edge of the second shell 220. The folding area 243 may form substantially the same plane with the first display area 241 and the second display area 242.

[0066] According to an embodiment, when the electronic device 200 is in a folded state (eg, Figure 3), the first housing 210 and the second housing 220 may be arranged to face each other. The surface of the first display area 241 and the surface of the second display area 242 of the display 240 may be angled at a small angle (e.g., an angle between 0 degrees and 10 degrees) while substantially facing each other. An angle between 0 degrees and 15 degrees or between 0 degrees and 20 degrees may also be referred to as a small angle, but the present invention is not limited thereto. At least a portion of the folding area 243 may be formed as a curved surface having a predetermined curvature. In an embodiment, although not shown, when the electronic device is in a folded state, the surface of the first back cover 280 and the surface of the second back cover 290 may substantially face each other while forming a narrow angle therebetween. In an electronic device that is folded so that the surface of the first back cover 280 and the surface of the second back cover 290 face each other, in the folded state, the first display area 241 may be visually exposed to the outside of the electronic device in a direction opposite to the second display area 242, and the folding area 243 may be visually exposed to the outside of the electronic device in a state where a curved surface having a predetermined curvature is formed. For example, the portion visually exposed to the outside in the folded state may vary depending on the structure of the electronic device 200 . It should be noted that the embodiments of the present disclosure are not limited to the structure shown in the drawings.

[0067] According to an embodiment, when the electronic device 200 is in the intermediate state, the first housing 210 and the second housing 220 may be provided with a certain angle therebetween. The surface of the first display area 241 and the surface of the second display area 242 of the display 240 may form an angle that is greater than the angle in the folded state and less than the angle in the unfolded state. The folding area 243 may at least partially have a curved surface having a predetermined curvature, and in this case, the curvature may be less than the curvature when it is in the folded state.

In an embodiment, the hinge module 202 may be disposed inside the housing 201 to rotatably connect the first housing 210 and the second housing 220.

[0071] According to an embodiment, the first housing 210 and the second housing 220 may be assembled together to be coupled to two opposite sides of the hinge module 202. According to an embodiment, the first housing 210 may include a first support area 212 (e.g., a first support plate or a first support member) that may support components of the electronic device 200 (e.g., a first circuit board 262 and / or a first battery 252) and a first side wall 211 surrounding at least a portion of the first support area 212.

[0073] According to an embodiment, the sub display 244 may display a screen in a direction different from the display areas 241 and 242. For example, the sub display 244 may output a screen in a direction opposite to the first display area 241. According to an embodiment, the sub display 244 may be provided on the first rear cover 280.

[0074] According to an embodiment, the battery 250 may include a first battery 252 disposed in the first housing 210 and a second battery 254 disposed in the second housing 220. According to an embodiment, the first battery 252 may be disposed on a first circuit board 262, and the second battery 254 may be disposed on a second circuit board 264. In an embodiment, the first circuit board 262 may be disposed on the same plane as at least a portion of the first battery 252, and the second circuit board 264 may be disposed on the same plane as at least a portion of the second battery 254.

[0075] According to an embodiment, the board unit 260 may include a first circuit board 262 disposed in the first housing 210 and a second circuit board 264 disposed in the second housing 220. According to an embodiment, the board unit 260 may include at least one flexible printed circuit board 266 for electrically connecting the first circuit board 262 and the second circuit board 264 to each other. According to an embodiment, at least a portion of the flexible printed circuit board 266 may be disposed on the hinge module 202. According to an embodiment, the first circuit board 262 and the second circuit board 264 may be disposed in a space formed by the first housing 210, the second housing 220, the first back cover 280, and the second back cover 290. Components for implementing various functions of the electronic device 200 may be disposed on the first circuit board 262 and the second circuit board 264.

[0076] According to an embodiment, the electronic device 200 may include a speaker module 208. According to an embodiment, the speaker module 208 may convert an electrical signal into sound. According to an embodiment, the speaker module 208 may be disposed in a space formed by the first housing 210, the second housing 220, the first back cover 280, and the second back cover 290.

[0077] In the following detailed description, a configuration in which the first housing 210 and the second housing 220 are connected or coupled via a hinge module (or referred to as a "hinge structure") so as to be rotatable may be described as an example. However, it should be noted that the embodiments do not limit the electronic device according to the embodiments of the present disclosure. For example, the electronic device according to the embodiments of the present disclosure may include three or more housings. In the embodiments disclosed below, "a pair of housings" may refer to two rotatably coupled housings among three or more housings.

[0078] Figures 2 to 4 The electronic device 200 disclosed in the embodiment has the appearance of a foldable electronic device, but the present invention is not limited thereto. For example, the electronic device shown may be a bar-type, a flat-type, or a rollable electronic device. A "rollable electronic device" may refer to a device at least a portion of which may be rolled or curled or housed in a housing (e.g., Figure 2 The electronic device in the housing 201) is not provided with a display (eg, Figure 4The display 240 of the rollable electronic device can be bent and deformed. As the display is stretched or exposed to the outside with a larger area according to user needs, the rollable electronic device can use the expanded second display area.

[0079] Figure 5 is a rear view showing the internal configuration of the electronic device 300 according to the embodiment of the present disclosure. Figure 6 The present invention is shown in Figure 5 An enlarged view of portion “E” of electronic device 300 .

[0080] Figure 5 and Figure 6 The electronic device 300 can be used with Figures 1 to 4 The electronic devices 101 and 200 are at least partially identical. In an embodiment, Figure 5 and Figure 6 The electronic device 300 may be substantially the same as Figures 1 to 4 The electronic devices 101 and 200 are the same. Figure 5 and Figure 6 When the electronic device 300 is described, components that can be easily understood by the previous embodiment may be marked with the same or different reference numerals, and their detailed description may be omitted. Figures 1 to 4 The components of the electronic device 101 or 200 may be applied to Figure 5 and Figure 6 Components omitted in the description of the electronic device 300.

[0081] refer to Figure 5 and Figure 6 , the electronic device 300 may include a first shell 210 and a second shell 220 rotatably coupled to each other by a hinge module 202, and an electromagnetic sensor 323a and an electromagnetic member 323b respectively disposed in corresponding ones of the first shell 210 and the second shell 220. For example, when the electromagnetic sensor 323a is disposed in the first shell 210, the electromagnetic member 323b may be disposed in the second shell 220. Similarly, when the electromagnetic sensor 323a is disposed in the second shell 220, the electromagnetic member 323b may be disposed in the first shell 210. In an embodiment, the electromagnetic member 323b may generate an electromagnetic field, and the electromagnetic sensor 323a may detect the electromagnetic field generated by the electromagnetic member 323b. For example, when the first shell 210 and the second shell 220 rotate relative to each other, the electromagnetic sensor 323a may detect the electromagnetic field (e.g., a change in magnetic flux density). In an embodiment, the electronic device 300 (e.g., Figure 1The processor 120 may determine or calculate the folding state of the second shell 220 relative to the first shell 210 or the tilt angle of the second shell 220 relative to the first shell 210 based on the change in magnetic flux density detected by the electromagnetic sensor 323a (or the currently detected magnetic flux density).

[0082] According to an embodiment, the hinge module 202 may include a first hinge plate 202a and a second hinge plate 202b rotatably coupled to each other. For example, the first hinge plate 202a and the second hinge plate 202b may be disposed on a hinge cover (eg, Figure 4 The hinged cover 230) is provided with a folding axis (e.g. Figure 2 In an embodiment, the first hinge plate 202a may be disposed on one edge of the first housing 210, and the second hinge plate 202b may be disposed on one edge of the second housing 220. For example, the first hinge plate 202a may be substantially mounted or fixed inside the first housing 210, and the second hinge plate 202b may be substantially mounted or fixed inside the second housing 220. Therefore, the hinge module 202 may rotatably connect the first housing 210 and the second housing 220.

[0083] According to an embodiment, the first circuit board 262 may be at least partially arranged along the Y-axis direction together with the first battery 252. In an embodiment, a portion of the first circuit board 262 may be disposed in a region between the first battery 252 and the folding axis A. In an embodiment, the second circuit board 264 may be at least partially arranged along the Y-axis direction together with the second battery 254. In an embodiment, a portion of the second circuit board 264 may be disposed in a region between the second battery 254 and the folding axis A. For example, a portion of the first circuit board 262 and a portion of the second circuit board 264 may be disposed adjacent to each other with the folding axis A interposed therebetween.

[0084] According to an embodiment, the electromagnetic sensor 323a may include a three-dimensional (3D) Hall sensor that detects 3-axis directions (eg, Figure 4 The electromagnetic sensor 323a can detect the position or movement of the electromagnetic member 323b when the first shell 210 and the second shell 220 are unfolded or folded. In an embodiment, the electronic device 300 or the processor 120 can calculate or determine the position of the second shell 220 relative to the first shell 210 based on the information detected by the electromagnetic sensor 323a. In an embodiment, the electromagnetic sensor 323a can be disposed adjacent to the folding axis A. For example, at Figure 5 and Figure 6 In the state shown, the electromagnetic sensor 323 a may be substantially disposed on the first hinge plate 202 a within the first housing 210 .

[0085] According to an embodiment, the electromagnetic member 323b may include a permanent magnet (or Figure 8 Coil in). In an embodiment, when the first shell 210 and the second shell 220 are unfolded or folded, the electromagnetic member 323b can move relative to the electromagnetic sensor 323a. The advantage of using a permanent magnet is that it is not susceptible to failure. In contrast, using a coil can generate different electromagnetic fields, i.e., based on different currents applied to the coil. The electromagnetic field detected by the electromagnetic sensor 323a can change according to the movement of the electromagnetic member 323b, and the electromagnetic sensor 323a can generate information about the movement of the electromagnetic member 323b or the relative movement of the first shell 210 and the second shell 220 by detecting such changes in the electromagnetic field (or the current magnetic flux density). In an embodiment, the electromagnetic member 323b can be arranged near the folding axis A. For example, at Figure 5 and Figure 6 In the illustrated state, the electromagnetic member 323 b may be substantially disposed on the second hinge plate 202 b within the second housing 220 .

[0086] According to an embodiment, the intensity of the magnetic flux density may be inversely proportional to the square of the distance from the electromagnetic member 323b. For example, as the distance between the electromagnetic member 323b and the electromagnetic sensor 323a increases, the electromagnetic member 323b may be manufactured to have a specification of generating a greater electromagnetic force, or when the electromagnetic sensor 323a having a higher sensitivity is provided, the change in the magnetic flux density or the magnetic flux density may be accurately detected. In an embodiment, while ensuring that an electronic component provided nearby (e.g., a Figure 1 When a stable operating environment of the second housing 220 or the components of the communication module 190 is not provided, it may be difficult to set the electromagnetic member 323b that generates a large electromagnetic force. In the embodiment of the present disclosure, since the electromagnetic member 323b and the electromagnetic sensor 323a are arranged adjacent to the folding axis A, good accuracy can be ensured when detecting changes in magnetic flux density regardless of the electromagnetic force of the electromagnetic member 323b or the specifications of the electromagnetic sensor 323a. For example, the electronic device 300 according to the embodiment of the present disclosure can provide a stable operating environment for the electronic components arranged around the electromagnetic member 323b while detecting the position of the second housing 220 relative to the first housing 210.

[0087] According to an embodiment, the first hinge plate 202a and / or the second hinge plate 202b may include a portion that transmits an electromagnetic field. For example, when at least the first housing 210 and the second housing 220 are in an unfolded state, the portion that transmits an electromagnetic field may be disposed between the electromagnetic sensor 323a and the electromagnetic member 323b. For example, the first portion 321a that transmits an electromagnetic field and is also a portion of the first hinge plate 202a may be formed of an engineering plastic material such as polybutylene terephthalate (PBT) and may be disposed between the electromagnetic sensor 323a and the folding axis A. In an embodiment, the second portion 321b that is also a portion of the second hinge plate 202b and is also a portion of the electromagnetic field may be formed of an engineering plastic material such as PBT and may be disposed between the electromagnetic member 323b and the folding axis A.

[0088] According to an embodiment, the first portion 321a can concentrate the electromagnetic field generated by the electromagnetic member 323b onto the first portion 321a by using a ferromagnetic material having a higher relative magnetic permeability (e.g., having a relative magnetic permeability of about 10 or more) than other portions of the first hinge plate 202a. Examples of ferromagnetic materials include, but are not limited to, materials such as iron, μ metal, ferrite, permalloy, carbon steel, and / or nickel. The first portion 321a can be manufactured to be attached to the surface of the first housing 210 (or the first hinge plate 202a) in the form of a ferrite sheet, or to be manufactured in a manner that the ferromagnetic material is insert-molded into the first housing 210.

[0089] According to an embodiment, the second part 321b can concentrate the electromagnetic field generated by the electromagnetic member 323b to the second part 321b by using a ferromagnetic material having a higher relative magnetic permeability (e.g., having a relative magnetic permeability of about 10 or more) than other parts of the first hinge plate 202a. Examples of ferromagnetic materials include, but are not limited to, materials such as iron, μ metal, ferrite, permalloy, carbon steel, and / or nickel. The second part 321b can be attached to the surface of the second housing 220 (or the second hinge plate 202b) in the form of a ferrite sheet, or manufactured in a manner that the ferromagnetic material is insert-molded into the first housing 220.

[0090] According to an embodiment, at a first position (e.g., Figure 3In the folded state), the electromagnetic sensor 323a and the electromagnetic member 323b can be set in a position that substantially faces each other. It should be noted that since the electromagnetic sensor 323a and the electromagnetic member 323b are not visually exposed to the external space, the electromagnetic sensor 323a and the electromagnetic member 323b do not directly face each other even in the first position. As the second shell 202 is unfolded from the first position relative to the first shell 210 or the electromagnetic sensor 323a, the electromagnetic member 323b can gradually move away from the electromagnetic sensor 323a. For example, as the second shell 220 is unfolded from the first position, the intensity of the electromagnetic field detected by the electromagnetic sensor 323a can gradually decrease. The electronic device 300 (for example, Figure 1 The processor 120 may calculate an angle at which the second shell 220 is deployed from the first position based on a change in magnetic flux density or a currently detected magnetic flux density.

[0091] According to an embodiment, in the second position (e.g., the unfolded state), the electromagnetic sensor 323a, the first part 321a, the second part 321b and the electromagnetic member 323b may be arranged in sequence along a direction intersecting the folding axis A (e.g., the X-axis direction). For example, in the second position, the first part 321a and the second part 321b may be disposed between the electromagnetic sensor 323a and the electromagnetic member 323b to transmit the electromagnetic field generated by the electromagnetic member 323b and guide the electromagnetic field to the electromagnetic sensor 323a. For example, the first part 321a and the second part 321b may have different magnetic permeabilities relative to other parts of the first hinge plate 202a or the second hinge plate 202b, so that the electromagnetic field generated in the electromagnetic member 323b may be distributed in the direction in which the electromagnetic sensor 323a is disposed. In an embodiment, when distributing the electromagnetic field generated in the electromagnetic member 323b in the direction in which the electromagnetic sensor 323a is disposed, the first part 321a and the second part 321b may have a linear waveguide shape or a tapered waveguide shape. Figure 6 In the embodiment of the present invention, the first portion 321a and / or the second portion 321b are shown as being substantially conical. In an embodiment, in the second position (eg, the deployed state), the electromagnetic sensor 323a, the first portion 321a, the second portion 321b, and the electromagnetic member 323b may be at least partially arranged on the same plane.

[0092] According to an embodiment, when the electromagnetic sensor 323a is disposed closer to the folding axis A or the electromagnetic member 323b, the electronic device 300 may further include a first wiring board 362a extending from the first circuit board 262. The first wiring board 362a may be, for example, a flexible printed circuit board, and the electromagnetic sensor 323a may be disposed on the first wiring board 362a between the folding axis A and the first circuit board 262 or between the first portion 321a and the first circuit board 262. For example, the electromagnetic sensor 323a may be electrically connected to the first circuit board 262 by using the first wiring board 362a, and may be disposed close to the electromagnetic member 323b. As described above, since the first wiring board 362a is disposed, even if the electromagnetic sensor 323a having a slightly lower sensitivity is disposed, the electromagnetic field may be easily detected. According to an embodiment, even if the first wiring board 362a is not used, when the electromagnetic sensor 323a may sufficiently detect the electromagnetic field generated by the electromagnetic member 323b, the electromagnetic sensor 323a may be disposed on the first circuit board 262. The example in which the electromagnetic sensor 323a is disposed on the first circuit board 262 will be referred to. Figure 7 Give a description.

[0093] According to an embodiment, in Figures 4 to 6 In the structure shown in , as the second shell 220 rotates, the position of the electromagnetic member 323b relative to the electromagnetic sensor 323a can change in the Z-axis direction and / or the X-axis direction. For example, in a structure in which the second shell 220 rotates around the folding axis A parallel to the Y-axis direction and the electromagnetic sensor 323a and the electromagnetic member 323b are aligned along the X-axis direction in the unfolded state, even if the second shell 220 rotates, the electromagnetic member 323b can remain substantially fixed relative to the electromagnetic sensor 323a in the Y-axis direction. Therefore, when Figures 4 to 6 When the electronic device 200 or 300 is configured to detect electromagnetic fields in three-axis directions, the electromagnetic sensor 323a can detect electromagnetic fields in at least the Z-axis direction and / or at least the X-axis direction, and the electronic device 200 or 300 or the processor 120 can determine the position or displacement of the electromagnetic component 323b and / or the second shell 220 based on the detected information.

[0094] According to an embodiment, the electromagnetic field change detected by the electromagnetic sensor 323a can be changed based on the shape of the electromagnetic member 323b. For example, when the electromagnetic member 323b has a flat plate (e.g., a disk) shape, the position of the electromagnetic member 323b can be more accurately calculated based on the Z-axis displacement between the first position and the approximately 45-degree angle position, and the position of the electromagnetic member 323b can be more accurately calculated based on the X-axis displacement from the approximately 45-degree angle position to the unfolded position. Therefore, the electronic device 200 or 300 or the processor 120 can calculate the folding state or tilt angle of the second shell 220 based on the partial data detected by the electromagnetic sensor 323a according to the position of the second shell 220 relative to the first shell 210. The configuration for calculating or determining the relative position of the second shell 220 relative to the first shell 210 will be described again in the embodiments described below.

[0095] Figure 7 is a diagram showing an electronic device (eg, Figures 2 to 5 An enlarged view of a portion of the electronic device 200 and 300 ).

[0096] refer to Figure 7 , a separate wiring board can be omitted (e.g. Figure 6 The electromagnetic sensor 323a may be provided on the first circuit board 262. For example, the electromagnetic sensor 323a may be provided on the first circuit board 262 according to the specifications of the electromagnetic member 323b, the sensitivity of the electromagnetic sensor 323a, and the shapes (or magnetic permeabilities) of the first part 321a and the second part 321b. In an embodiment, the first part 321a or the second part 321b may have a substantially linear waveguide shape, and may be in an unfolded state (e.g., Figure 3 321a and the second position shown in FIG. 321b) are aligned substantially parallel to the X-axis between the electromagnetic sensor 323a and the electromagnetic member 323b. For example, it should be noted that the arrangement of the electromagnetic sensor 323a and / or the description of the shapes of the first portion 321a and the second portion 321b do not limit the embodiments of the present disclosure, and can be appropriately selected or combined according to the specific design or internal structure of the electronic devices 200 and 300. Although a specific shape will be described, the present invention is not limited thereto.

[0097] Figure 8 is a diagram showing an electronic device (eg, Figures 2 to 5 An enlarged view of a portion of the electronic device 200 and 300 ).

[0098] and Figure 6 Compared with the embodiment, Figure 8 Embodiments of the invention may differ in configuration: the electromagnetic member 423b includes a coil (eg, a solenoid coil). Figure 8In the following description of the embodiments of the present invention, components that are easily understood from the description of the previous embodiments are denoted by the same reference numerals or no reference numerals, and their detailed descriptions may be skipped. Figure 5 or Figure 6 The components of the embodiments may be applied to Figure 8 Components omitted in the description of the embodiments.

[0099] refer to Figure 8 , the electromagnetic member 423b may be disposed in the second housing 220 (eg, Figure 5 In the second housing 220 of the present invention, for example, on the second hinge plate 202b. In an embodiment, the electromagnetic member 423b may be implemented in the form of a coil wound at least once, and may generate an electromagnetic field by receiving an electrical signal from the outside. In an embodiment, when the electromagnetic member 423b includes a coil, the electronic device 200 or 300 may include a second wiring board 464a extending from the second circuit board 264. The second wiring board 464a may include, for example, a cable or a wire, and may electrically connect the electromagnetic member 423b to the second circuit board 264.

[0100] According to an embodiment, the second wiring board 464a may include a printed circuit pattern formed on a synthetic resin film. When the second wiring board 464a includes a printed circuit pattern, the electromagnetic member 423b (e.g., a coil) may be substantially a part of the printed circuit pattern of the second wiring board 464a. For example, the electromagnetic member 423b may be disposed on the second wiring board 464a. In an embodiment, when the electronic device 200 or 300 includes a second circuit board 264, the electromagnetic member 423b may be disposed between the folding axis A and the second circuit board 264, or between the second portion 321b and the second circuit board 264.

[0101] According to an embodiment, when the electromagnetic member 423b is implemented as a coil, the strength of the electromagnetic field can be adjusted by controlling the current strength applied to the coil. For example, when the electromagnetic member 423b is implemented as a coil, a stable operating environment can be provided for other surrounding electronic components. When the amount of current applied to the coil is reduced, or when the distance between the coil (e.g., the electromagnetic member 423b) and the electromagnetic sensor 323a increases, the electromagnetic sensor 323a may be limited in detecting the electromagnetic field generated in the coil due to the influence of the electromagnetic field of the surrounding environment. In an embodiment, the electronic device 200 or 300 or the processor 120 can change the amount of current applied to the coil (e.g., the electromagnetic member 423b) according to the electromagnetic field strength detected by the electromagnetic sensor 323a. For example, the electronic device 200 or 300 or the processor 120 can determine or calculate the tilt angle or position of the second housing 220 relative to the first housing 210 by combining data related to the electromagnetic field strength detected by the electromagnetic sensor 323a and data related to the current amount applied to the coil. In this way, a measurement that is not easily affected by failure can be achieved.

[0102] Fig. 9 is a block diagram 900 illustrating an electronic device according to an embodiment.

[0103] refer to Fig. 9 , electronic device 901 (eg, Figure 1 electronic device 101, Figure 2 and Figure 3 The electronic device 200 and Figure 5 The electronic device 300 ) may include a folding angle detector 950 and a memory 930 .

[0104] Fig. 9 At least some of the components of the electronic device 901 shown in FIG. 9 may be connected to Figure 1 The components of the electronic device 101 are the same or similar, and redundant descriptions will be omitted below.

[0105] According to an embodiment, the processor 920 may be substantially the same as Figure 1 The processor 120 is implemented identically or similarly to the processor 120 of FIG.

[0106] According to an embodiment, the processor 920 may control the folding and opening angle detector 950 to detect the second housing (eg, Figure 2 and Figure 3 The second housing 220) is relative to the first housing (eg, Figure 2 and Figure 3 The folding state or unfolding angle (hereinafter referred to as “folding opening / closing angle”) of the first housing 210 ) is determined.

[0107] According to an embodiment, while controlling the supply of current to the electromagnetic component 951 of the folding and opening angle detector 950, the processor 920 can measure the electromagnetic field generated in the electromagnetic component 951 based on the magnetic data received from the electromagnetic sensor 953 of the folding and opening angle detector 950, and can detect the folding opening / closing angle (folding opening / closing angle) corresponding to the electromagnetic field density or the magnetic field density in the folding opening / closing angle table stored in the memory 930.

[0108] According to an embodiment, the processor 920 may identify a change in electromagnetic field density or a change in magnetic field density compared to a previous electromagnetic field density or magnetic field density generated by the electromagnetic member 951 of the folding and opening angle detector 950 based on magnetic data received from the electromagnetic sensor 953 of the folding and opening angle detector 950, and when it is identified that the changed electromagnetic field density or magnetic field density reaches a threshold value, control to increase or decrease the current supplied to the electromagnetic member 951 of the folding and opening angle detector 950. Here, the "threshold" (i.e., the first threshold) when unfolded may be set to be different from the "threshold" (i.e., the second threshold) when folded. In an embodiment, the first threshold when unfolded may be set to an electromagnetic field density (or magnetic field density) lower than the second threshold when folded. After controlling to increase or decrease the current supplied to the electromagnetic member 951 of the folding and opening angle detector 950, the processor 920 may measure the electromagnetic field generated from the electromagnetic member 951 based on the magnetic data received from the electromagnetic sensor 953, and detect the folding and opening angle corresponding to the electromagnetic field density in the folding and opening angle table stored in the memory 930. When it is identified that the changed electromagnetic field density reaches a threshold value, the processor 920 can increase or decrease the current supplied to the electromagnetic member 951 of the folding opening and closing angle detector 950, thereby preventing the electromagnetic field density from decreasing to a noise level. In this way, it can be ensured that the signal level used to perform the opening and closing angle detection is always higher than the noise level.

[0109] According to an embodiment, in response to identifying that the changed electromagnetic field density reaches a first threshold, processor 920 may provide a second current higher than the first current provided to electromagnetic member 951 to prevent the changed electromagnetic field density from decreasing to a noise level.

[0110] According to an embodiment, in response to identifying that the changed electromagnetic field density reaches a second threshold greater than the first threshold, processor 920 may provide a first current to the electromagnetic member that is lower than a second current provided to electromagnetic member 951 because the changed electromagnetic field density is not reduced to a noise level.

[0111] According to an embodiment, the processor 920 can identify changes in the electromagnetic field density generated by the electromagnetic component 951 of the folding and opening angle detector 950 based on the magnetic data received from the electromagnetic sensor 953 of the folding and opening angle detector 950, and when it is identified that the changed electromagnetic field density does not reach the threshold, the folding and opening angle corresponding to the changed electromagnetic field density can be detected in the folding and opening angle table stored in the memory 930.

[0112] According to an embodiment, the processor 920 may identify the type of axis capable of detecting the folding and opening angle corresponding to the electromagnetic field density in the folding and opening angle table stored in the memory 930 (eg, Figure 4 For example, when the electromagnetic sensor 953 is a 3D sensor, the processor 920 may obtain at least one of the magnetic data of the X-axis, the magnetic data of the Y-axis, and the magnetic data of the Z-axis from the electromagnetic sensor 953, and the type of axis using the magnetic data may be different depending on the folding opening and closing angle. Therefore, the electromagnetic field density, the axis type, and the folding opening and closing angle value may be mapped and stored in the folding opening and closing angle table.

[0113] According to an embodiment, the processor 920 may identify the type of axis to which the folding and opening angle value is mapped among the multiple axes mapped to the electromagnetic field density in the folding and opening angle table stored in the memory 930, and may detect the folding and opening angle value matching the identified axis. For example, when the folding and opening angle value mapped to the first axis (e.g., X-axis) among the multiple axes mapped to the electromagnetic field density cannot be detected, the processor 920 may detect the folding and opening angle mapped to the second axis (e.g., Y-axis) among the multiple axes that is different from the first axis (e.g., X-axis), and when the folding and opening angle mapped to the second axis (e.g., Y-axis) cannot be detected, the processor 920 may detect the folding and opening angle mapped to the third axis (e.g., Z-axis) among the multiple axes that is different from the second axis (e.g., Y-axis).

[0114] According to an embodiment, the folding angle detector 950 may include an electromagnetic member 951 (eg, Figure 5 and Figure 6 The electromagnetic member 323b in the embodiment of the present invention and the electromagnetic sensor 953 (for example, Figure 5 and Figure 6 The electromagnetic sensor 323a in FIG.

[0115] According to an embodiment, the electromagnetic member 951 may be disposed in a first housing (eg, Figure 2 and Figure 3 In the first shell 210), current can be received under the control of the processor 920, and different electromagnetic fields can be generated according to the change of the folding and opening angle.

[0116] According to an embodiment, the electromagnetic member 951 may include a coil.

[0117] According to an embodiment, the electromagnetic sensor 953 may be disposed in a second housing (eg, Figure 2 and Figure 3 In the second shell 220 ), magnetic data of the electromagnetic field generated by the electromagnetic sensor 953 can be acquired, and the acquired magnetic data can be sent to the processor 920.

[0118] According to an embodiment, the electromagnetic sensor 953 may include a magnetic sensor, a 3D magnetic sensor, a Hall sensor, or a 3D Hall sensor. However, the magnetic sensor is not limited to the above sensors.

[0119] According to an embodiment, the memory 930 may be implemented substantially as Figure 1 The memory 130 is the same or similar.

[0120] According to an embodiment, a folding opening and closing angle table may be stored in the memory 930, and the density of the electromagnetic field, the type of the axis, and the folding opening and closing angle value may be mapped to each other and stored in the folding opening and closing angle table.

[0121] Fig.10 1000 is a flowchart showing how to detect a folding and opening angle using an electromagnetic field in an electronic device according to an embodiment. The operation of detecting the folding and opening angle may include operations 1001 to 1017. In the following embodiments, the operations may be performed sequentially, but may also be performed non-sequentially. For example, the order of the operations may be changed, at least two operations may be performed in parallel, or other operations may be added.

[0122] In operation 1001, an electronic device 901 (eg, Figure 1 electronic device 101, Figure 2 and Figure 3 The electronic device 200, Figure 5 The electronic device 300 and / or Fig. 9 The electronic device 901 can be based on the electromagnetic sensor (e.g., Figure 5 and Figure 6 The electromagnetic sensor 323a and / or Fig. 9 The electromagnetic sensor 953) receives magnetic data to measure the magnetic field generated by the electromagnetic member (e.g., Figure 5 and Figure 6 The electromagnetic member 323b and / or Fig. 9 The electromagnetic field generated by the electromagnetic component 951).

[0123] According to an embodiment, the electronic device may control the folding opening and closing angle detector (eg, Fig. 9While supplying current to the electromagnetic member of the folding and opening angle detector 950 , the electromagnetic field generated in the electromagnetic member is measured based on the magnetic data received from the electromagnetic sensor of the folding and opening angle detector.

[0124] In operation 1003, the electronic device 901 (eg, Figure 1 electronic device 101, Figure 2 and Figure 3 The electronic device 200, Figure 5 The electronic device 300 and / or Fig. 9 The electronic device 901) can detect (or calculate) the folding and opening angle corresponding to the electromagnetic field density.

[0125] According to an embodiment, the electronic device may detect the folding and opening angle corresponding to the electromagnetic field density in a folding and opening angle table stored in a memory of the electronic device (eg, memory 930). The table may also be referred to as a lookup table (LUT).

[0126] In operation 1005, the electronic device 901 (eg, Figure 1 electronic device 101, Figure 2 and Figure 3 The electronic device 200, Figure 5 The electronic device 300 and / or Fig. 9 The electronic device 901) can identify whether the density of the electromagnetic field changes.

[0127] According to an embodiment, the electronic device may detect the folding and opening angle based on an electromagnetic sensor (eg, Figure 5 and Figure 6 The electromagnetic sensor 323a and / or Fig. 9 The electromagnetic sensor 953) receives magnetic data to identify when the electromagnetic member of the folding opening and closing angle detector (for example, Figure 5 and Figure 6 The electromagnetic member 323b and / or Fig. 9 The change in electromagnetic field density when the electromagnetic field density generated by the electromagnetic component 951) is compared with the previous electromagnetic field density.

[0128] When a change in the electromagnetic field density is identified in operation 1005 , the electronic device may identify whether the changed electromagnetic field density reaches a threshold value in operation 1007 .

[0129] In operation 1007, upon recognizing that the changed electromagnetic field density reaches a threshold value, the electronic device may increase or decrease the power provided to the electromagnetic member (eg, Figure 5 and Figure 6 The electromagnetic member 323b and / or Fig. 9 The current of the electromagnetic component 951).

[0130] According to an embodiment, when it is recognized that the changed electromagnetic field density reaches a first threshold, the electronic device can provide a second current higher than the first current provided to the electromagnetic member to prevent the changed electromagnetic field density from decreasing to a noise level. For example, the electromagnetic field density detected during deployment can gradually increase, and when the first threshold is reached, the current provided to the electromagnetic member can be increased.

[0131] According to an embodiment, when it is recognized that the changed electromagnetic field density reaches a second threshold greater than the first threshold, the electronic device can provide the electromagnetic member with a first current lower than the second current provided to the electromagnetic member because the changed electromagnetic field density is not reduced to the noise level. For example, the electromagnetic field density detected in the folding can gradually increase, and when the second threshold is reached, the current provided to the electromagnetic member can be reduced.

[0132] In operation 1011, the electronic device 901 (eg, Figure 1 electronic device 101, Figure 2 and Figure 3 The electronic device 200, Figure 5 The electronic device 300 and / or Fig. 9 The electronic device 901 can be based on the electromagnetic sensor (e.g., Figure 5 and Figure 6 The electromagnetic sensor 323a and / or Fig. 9 The electromagnetic sensor 953) receives magnetic data, measuring the magnetic field generated by the electromagnetic member (e.g., Figure 5 and Figure 6 The electromagnetic member 323b and / or Fig. 9 The electromagnetic field generated by the electromagnetic component 951).

[0133] According to an embodiment, the electronic device may control the increase or decrease of the amount of power provided to the folding and opening angle detector (for example, Fig. 9 After the current of the electromagnetic member of the folding opening and closing angle detector 950 is supplied, the electromagnetic field generated in the electromagnetic member is measured based on the magnetic data received from the electromagnetic sensor.

[0134] In operation 1013, the electronic device 901 (eg, Figure 1 electronic device 101, Figure 2 and Figure 3 The electronic device 200, Figure 5 The electronic device 300 and / or Fig. 9 The electronic device 901) can detect the folding and opening angle corresponding to the electromagnetic field density.

[0135] According to an embodiment, the electronic device may detect a memory (eg, Fig. 9The folding and opening angles corresponding to the electromagnetic field density are in the folding and opening angle table in the memory 930).

[0136] When it is identified in operation 1007 that the changed electromagnetic field density fails to reach the threshold value, the electronic device may, in operation 1015, generate a signal based on the electromagnetic field density from the electromagnetic sensor (eg, Figure 5 and Figure 6 The electromagnetic sensor 323a and / or Fig. 9 The electromagnetic sensor 953 receives magnetic data and measures the magnetic field of the electromagnetic member (e.g., Figure 5 and Figure 6 The electromagnetic member 323b and / or Fig. 9 The electromagnetic field generated in the electromagnetic component 951).

[0137] According to an embodiment, the electronic device may control the folding opening and closing angle detector (eg, Fig. 9 While supplying the same current as before to the electromagnetic member of the folding opening and closing angle detector 950 , the electromagnetic field generated in the electromagnetic member is measured based on the magnetic data received from the electromagnetic sensor.

[0138] In operation 1017, the electronic device 901 (eg, Figure 1 electronic device 101, Figure 2 and Figure 3 The electronic device 200, Figure 5 The electronic device 300 and / or Fig. 9 The electronic device 901) can detect the folding and opening angle corresponding to the electromagnetic field density.

[0139] According to an embodiment, the electronic device may detect a folding and opening angle corresponding to the electromagnetic field density in a folding and opening angle table stored in the electronic device (eg, the memory 930 ).

[0140] Fig.11 1100 is a diagram illustrating an operation of detecting a folding and opening angle using an electromagnetic field in an electronic device according to an embodiment.

[0141] refer to Fig.11 , electronic devices (e.g. Figure 1 electronic device 101, Figure 2 and Figure 3 The electronic device 200, Figure 5 The electronic device 300 and / or Fig. 9 The electronic device 901) can control the second housing of the electronic device (for example, Figure 2 and Figure 3 The second housing 220 of the electronic device is opposite to the first housing (eg, Figure 2 and Figure 3When the first housing 210 of the embodiment is in the unfolded state (for example, when the folding opening and closing angle is 0 degrees), the folding opening and closing angle detector (for example, Fig. 9 The electromagnetic member (e.g., Figure 5 and Figure 6 The electromagnetic member 323b and / or Fig. 9 The electromagnetic member 951 of the folding opening and closing angle detector provides a first current c1. While controlling the first current c1 to be provided to the electromagnetic member, the electronic device may generate a first current c1 based on the electromagnetic sensor (eg, Figure 5 and Figure 6 The electromagnetic sensor 323a and / or Fig. 9 The electromagnetic sensor 953) measures the electromagnetic field generated in the electromagnetic member and detects the magnetic data stored in the memory of the electronic device (e.g., Fig. 9 The folding and opening angles corresponding to the electromagnetic field density are in the folding and opening angle table in the memory 930).

[0142] The electronic device can measure the electromagnetic field generated in the electromagnetic member based on the magnetic data received from the electromagnetic sensor, and when it is identified that the measured electromagnetic field density reaches the first threshold value th, control the second current c2 higher than the first current c1 to be provided to the electromagnetic member. After controlling the second current c2 to be provided to the electromagnetic member, the electronic device can measure the electromagnetic field generated in the electromagnetic member based on the magnetic data received from the electromagnetic sensor, and detect the folding opening and closing angle corresponding to the electromagnetic field density in the folding opening and closing angle table stored in the memory of the electronic device. Therefore, the signal level is always kept above the noise level, and trouble-free measurement can be performed.

[0143] When the electromagnetic field density reaches the first threshold value th, the electronic device provides a second current c2 higher than the first current c1 to the electromagnetic member, thereby preventing the electromagnetic field density generated in the electromagnetic member from decreasing to a noise level (magnetic field noise floor) when the electronic device changes from an unfolded angle of the second shell relative to the first shell to a folded state.

[0144] The electronic device may measure the electromagnetic field generated in the electromagnetic member based on the magnetic data received from the electromagnetic sensor while controlling the second current c2 to be provided to the electromagnetic member, and when it is identified that the measured electromagnetic field density reaches a second threshold value greater than the first threshold value th, control the supply of the first current c1 lower than the second current c2 to the electromagnetic member. After controlling the supply of the first current c1 to the electromagnetic member, the electronic device may measure the electromagnetic field generated in the electromagnetic member based on the magnetic data received from the electromagnetic sensor, and detect the folding and opening angle corresponding to the electromagnetic field density in the folding and opening angle table stored in the memory of the electronic device.

[0146] Fig.12 1200 is a flowchart showing how to detect a folding and opening angle using an electromagnetic field in an electronic device according to an embodiment. The operation of detecting the folding and opening angle may include operations 1201 to 1211. In the following embodiments, the operations may be performed sequentially, but may also be performed non-sequentially. For example, the order of the operations may be changed, at least two operations may be performed in parallel, or other operations may be added.

[0147] In operation 1201, the electronic device 901 (eg, Figure 1 electronic device 101, Figure 2 and Figure 3 The electronic device 200, Figure 5 The electronic device 300 and / or Fig. 9 The electronic device 901) can load a folding and opening angle table to detect the folding and opening angle.

[0148] According to an embodiment, based on the folding and opening angle detector (for example, Fig. 9 The folding angle detector 950) is an electromagnetic sensor (for example, Figure 5 and Figure 6 The electromagnetic sensor 323a and / or Fig. 9 The electromagnetic sensor 953) receives magnetic data measured by the electromagnetic member of the folding opening and closing angle detector (e.g., Figure 5 and Figure 6 The electromagnetic member 323b and / or Fig. 9 When the electromagnetic member 951 generates an electromagnetic field, the electronic device can recognize the information stored in the memory of the electronic device (for example, Fig. 9 The folding and opening angle table in the memory 930).

[0149] In operation 1203, the electronic device 901 (eg, Figure 1 electronic device 101, Figures 2 to 3 The electronic device 200, Figure 5 The electronic device 300 and / or Fig. 9 The electronic device 901) can identify whether there is a folding opening and closing angle in the first axis information.

[0150] According to an embodiment, the electronic device may identify whether there is a folding and opening angle mapped to first axis (for example, x-axis) information among a plurality of axis information stored in the folding and opening angle table.

[0151] When it is recognized in operation 1203 that the folding opening and closing angle on the first axis exists, the electronic device may detect the folding opening and closing angle mapped to the first axis as the current folding opening and closing angle of the electronic device in operation 1205 .

[0152] When the electronic device does not identify the existence of the folding opening and closing angle in the first axis information in operation 1203 , the electronic device may identify whether there is a folding opening and closing angle mapped to the second axis information in operation 1207 .

[0153] According to an embodiment, the electronic device may identify whether there is a folding and opening angle mapped to second axis (for example, y-axis) information among a plurality of axis information stored in the folding and opening angle table.

[0154] When the presence of the folding and opening angle in the second axis information is identified in operation 1207 , the electronic device may detect the folding and opening angle mapped to the second axis information as the current folding and opening angle of the electronic device in operation 1209 .

[0155] When the presence of the folding and opening angle on the second axis information is not recognized in operation 1207 , the electronic device may detect the folding and opening angle mapped to the third axis information as the current folding and opening angle of the electronic device in operation 1211 .

[0156] According to an embodiment, the electronic device may detect the folding and opening angle mapped to the third axis (eg, z-axis) information among the plurality of axis information stored in the folding and opening angle table as the current folding and opening angle of the electronic device.

[0157] Fig.13a , Fig.13b , Fig.13c and Fig.13d 1301 , 1303 , 1305 , and 1307 are graphs showing changes in electromagnetic field density measured by an electromagnetic member in an electronic device according to an embodiment.

[0158] Fig.13a , Fig.13b , Fig.13c and Fig.13d is a graph showing scalar values ​​of magnetic data of an electromagnetic sensor that acquires an electromagnetic field generated in an electromagnetic member in a state in which the electromagnetic member (eg, a small disk-shaped magnet) is disposed in a first housing (eg, Figure 2 and Figure 3 The electromagnetic sensor (eg, a 3D electromagnetic sensor) is disposed in the electronic device (eg, Figure 1 electronic device 101, Figure 2 and Figure 3 The electronic device 200, Figure 5The electronic device 300 and / or Fig. 9 The second housing of the electronic device 901 (eg, Figure 2 and Figure 3 The second housing 220) includes a display area (eg, Figure 2 and Figure 3 The display area 240) is folded (eg, Figure 2 and Figure 3 folding region 243) or a folding axis extending parallel to the Y axis (e.g., Figure 2 and Figure 3 The folding axis A (axis A) is divided.

[0159] Fig.13a is a graph showing scalar values ​​of three axes (eg, X-axis, Y-axis, and Z-axis) of magnetic data generated in an electromagnetic member (eg, a small disk magnet) using an electromagnetic sensor (eg, a 3D electromagnetic sensor), Fig.13b is a graph showing the scalar value of magnetic data on the Y axis, Fig.13c is a graph showing the scalar value of magnetic data on the X-axis, Fig.13d : is a graph showing the scalar value of the magnetic data of the Z axis.

[0160] As shown in the figure, the folding and opening angle can be detected using magnetic data of the Z axis within the range of 0 degrees to 45 degrees, and the folding and opening angle can be detected using magnetic data of the X axis direction within the range of 45 degrees to 180 degrees.

[0161] Therefore, in the electronic device 901 (for example, Figure 1 electronic device 101, Figure 2 and Figure 3 The electronic device 200 and / or Fig. 9 A memory (eg, Fig. 9 In the folding and opening angle table stored in the memory 930), in order to accurately detect the folding and opening angle, the density of the electromagnetic field, the information about the axis (for example, the X-axis and the Z-axis), and the folding and opening angle value can be mapped to each other and stored.

[0162] As described above, the electronic device (eg, Figures 1 to 5 The electronic device 101, 200 or 300) can detect the first housing (eg, Figures 2 to 5 The first housing 210 and the second housing (eg, Figures 2 to 5 The relative position of the second housing 220) or even if an electromagnetic sensor (e.g., Figures 6 to 8The electromagnetic sensor 323a of the embodiment (for example, a three-dimensional Hall sensor) can also detect the partial direction of the screen display area. For example, even if the internal space of the electronic device is small, it can be easily installed. In the embodiment, although an electromagnetic sensor and / or an electromagnetic member (for example, as Figures 6 to 8 The permanent magnet or coil of the electromagnetic member 323b or 423b) is also easy to detect in a partial direction of the screen display area, so that the setting of additional sensors can be suppressed, thereby saving manufacturing costs. Since the electronic device can adjust the currently output screen based on the detected information about the relative position of the first shell and the second shell or the partial direction of the screen display area, the electronic device can provide a variety of user experiences suitable for the actual use environment. Since the electronic device adjusts the current supplied to the electromagnetic member based on the change in the electromagnetic field density or magnetic field density generated from the electromagnetic member, the electronic device can prevent the electromagnetic field generated from the electromagnetic member from decreasing to a noise level or increasing power consumption.
