The seventh digitizer area (417) is located below the seventh display area (337) and may overlap with the seventh display area (337). The eighth digitizer area (418) is located below the eighth display area (338) and can overlap with the eighth display area (338).

[0106] According to one embodiment of the present disclosure, based on data (e.g., the position of the tip (T) of the stylus (Y) in FIG. 5) detected by regions (411, 412, 413, 414, 415, 416, 417, 418) of a digitizer panel (410), it can be visually displayed through regions (331, 332, 333, 334, 335, 336, 337, 338) of a display (330) corresponding to each digitizer region (411, 412, 413, 414, 415, 416, 417, 418). For example, based on data detected by the first digitizer area (411), an image (e.g., a dot, a line, or a shape) may be displayed through the first display area (331). Based on data detected by the second digitizer area (412), an image may be displayed through the second display area (332). Based on data detected by the third digitizer area (413), an image may be displayed through the third display area (333). Based on data detected by the fourth digitizer area (414), an image may be displayed through the fourth display area (334). Based on data detected by the fifth digitizer area (415), an image may be displayed through the fifth display area (335).

Based on data detected by the eighth digitizer area (418), an image can be displayed through the eighth display area (338).

[0107] FIG. 11 is a front view of an electronic device (101) according to one embodiment of the present disclosure, equipped with an external case (E), showing an image displayed on a display (330) by a stylus (Y) before digitizer calibration. FIG. 12 is a front view of an electronic device (101) according to one embodiment of the present disclosure, equipped with an external case (E), showing an image displayed on a display (330) by a stylus (Y) after digitizer calibration.

[0108] The movement path of the tip (T) of the stylus (Y, see FIG. 5), described below with reference to FIG. 11 and FIG. 12, is a path along which the tip (T) of the stylus (Y) moves on the front surface (310A, see FIG. 2) of the electronic device (101). For example, it can be understood as a path along which the tip (T) of the stylus (Y) moves on the surface of the display (330) while in contact with the surface of the display (330). FIG. 11 and FIG. 12 respectively illustrate images formed when the tip (T) of the stylus (Y) is moved parallel to the X-axis and Y-axis shown in FIG. 11 and FIG. 12.

[0109] Referring to FIGS. 5, FIGS. 11 and FIGS. 12, digitizer calibration according to one embodiment of the present disclosure can be understood as an operation of calibrating the position of the tip (T) of the stylus (Y) calculated through a digitizer module (400, see FIG. 16) so that a point on the display (330) located below the tip (T) of the stylus (Y) and a point on the display (330) on which an image by the stylus (Y) is displayed substantially coincide, based on an external magnetic field (e.g., magnetic field (M3) of FIG. 6) recognized through a magnetic field sensor (1761). The position of the tip (T) of the stylus (Y) produced through the digitizer module (400) can be understood as a point (or area) on the digitizer panel (410) and / or a point (or area) on the display (330) that overlaps with the point (or area) on the digitizer panel (410).

[0110] According to one embodiment of the present disclosure, with reference to FIGS. 11 and 12, a plurality of lines (W1, W2) formed along the end (T) of a stylus (Y) may be displayed through a display (330). The plurality of lines (W1, W2) may include a plurality of horizontal lines (W1) and a plurality of vertical lines (W2). The plurality of horizontal lines (W1) may be understood as lines extending along the X-axis as shown in FIGS. 11 and 12. The plurality of horizontal lines (W1) may be arranged along the longitudinal direction (e.g., Y-axis direction) of the vertical lines (W2). The plurality of vertical lines (W2) may be understood as lines extending along the Y-axis as shown in FIGS. 11 and 12. The plurality of vertical lines (W2) may be arranged along the longitudinal direction (e.g., X-axis direction) of the horizontal lines (W1).

[0111] According to one embodiment of the present disclosure, FIG. 12 illustrates a plurality of lines (W1, W2) formed substantially parallel to the movement path of the end (T) of the stylus (Y). Compared to FIG. 12, FIG. 11 illustrates a plurality of lines (W1, W2) formed at a location deviating from the movement path of the end (T) of the stylus (Y) in one area (331, 332, 333, 334, 335, 336, 337, 338) of the display (330).

[0112] According to one embodiment of the present disclosure, a plurality of lines (W1, W2) may be distorted in various ways depending on the strength and / or shape of a magnetic field outside the electronic device (101) (e.g., a magnetic field (M3) by a magnet array (E1) of an outer case (E), see FIG. 5). The distortion of the plurality of lines (W1, W2) may be understood as a case where a point on the digitizer panel (410) (or a point on the display (330)) calculated at the position of the tip (T) of the stylus (Y) and the movement path of the tip (T) of the stylus (Y) on the display (330) are different from each other.

[0113] As an example, FIG. 11 illustrates a distorted appearance in which a plurality of lines (W1, W2) displayed in a region (331, 332, 333, 334, 335, 336, 337, 338) of a display (330) are moved away from the center of the region (331, 332, 333, 334, 335, 336, 337, 338) of the display (330) (e.g., the center of the wireless charging coil (391) in FIG. 7). As another example, due to the failure to recognize the position of the stylus (Y) and / or end (T) at one point of the digitizer panel (410), multiple lines (W1, W2) may be formed in a partially broken or distorted shape in a direction different from the direction shown in FIG. 11 in one area (331, 332, 333, 334, 335, 336, 337, 338) of the display (330).

[0114] FIG. 12 illustrates that the digitizer calibration is performed based on a magnetic field outside the electronic device (101) (e.g., a magnetic field (M3) by a magnetic array (E1) of an outer case (E)), so that a plurality of lines (W1, W2) are formed substantially parallel to the movement path of the tip (T) of the stylus (Y) despite the presence of a magnetic field outside the electronic device (101).

[0115] FIG. 13 illustrates a wireless charger (C) aligned with an electronic device (101) according to one embodiment of the present disclosure. FIG. 14 illustrates a user interface (UI) displayed through a display (330) in scan mode according to one embodiment of the present disclosure. The description of the wireless charger (C) described below may be applied substantially identically to external accessories including magnetic materials, provided they are not positioned relative to each other.

[0116] Referring to FIGS. 13 and 14, according to one embodiment of the present disclosure, a wireless charger (C) for delivering power to a wireless charging coil (391) may be disposed on the outside (e.g., rear) of an electronic device (101). The wireless charger (C) may include magnets (not shown) that are coupled to a magnet array (E1) of an outer case (E). By the magnets (not shown) of the wireless charger (C) being coupled to the magnet array (E1) of the outer case (E), the centers of the wireless charger (C) and the wireless charging coil (391) may be aligned. By aligning the centers of the wireless charger (C) and the wireless charging coil (391), the wireless charging efficiency of the electronic device (101) may be improved.

[0117] According to one embodiment of the present disclosure, a magnetic field sensor (1761, see FIG. 6) may be configured to recognize information (e.g., strength and / or direction) about a magnetic field outside the electronic device (101). As one example, the magnetic field outside the electronic device (101) may include a magnetic field from an external case (E) and / or a wireless charger (C). As another example, the magnetic field outside the electronic device (101) may include a magnetic field from an external accessory (e.g., a card wallet) containing a magnetic material.

[0118] According to one embodiment of the present disclosure, the external accessory (e.g., wireless charger (C)) may include a magnetic body extending along a magnetic array (E1) of an external case (E). The magnetic body included in the external accessory (e.g., wireless charger (C)) may be coupled with the magnetic array (E1) of the external case (E). As an example, the magnetic body included in the external accessory (e.g., wireless charger (C)) may have a shape extending along the circumference of a wireless charging coil (391) so as to overlap with the magnetic array (E1) of the external case (E) of the electronic device (101).

[0119] According to one embodiment of the present disclosure, an electronic device (101) may perform a scan mode to form a magnetic field distribution of an external accessory. As an example, the electronic device (101) may perform the scan mode by input from a user. In the scan mode, an external accessory (e.g., a wireless charger (C)) is placed on the outside (e.g., rear) of the electronic device (101), and by rotating the electronic device (101) with respect to the external accessory, a magnetic field distribution of the magnetic material of the external accessory (e.g., a wireless charger (C)) combined with the magnetic array (E1) of the external case (E) may be formed.

[0120] As an example, the magnetic field distribution map may be understood as data matching the strength and / or direction of the magnetic field acting on the first digitizer area (411, see FIG. 10) to the eighth digitizer area (418, see FIG. 10) and each digitizer area (411, 412, 413, 414, 415, 416, 417, 418, see FIG. 10) of the digitizer panel (410, see FIG. 10) by an external accessory (e.g., wireless charger (C)).

[0121] Referring to FIGS. 6 and FIGS. 13, according to one embodiment of the present disclosure, a magnetic field sensor (1761) may be placed in a region of the edge of the wireless charging coil (391). A portion of the magnetic array (E1) of the outer case (E) may overlap with the magnetic field sensor (1761). The magnetic field sensor (1761) may obtain information (e.g., strength and / or direction) regarding the magnetic field of a portion of the magnetic array (E1) of the outer case (E) through a sensing hole (393H). The magnetic array (E1) of the outer case (E) and the magnetic material of the outer accessory (e.g., wireless charger (C)) may have an annular shape extending along the edge of the wireless charging coil (391). The magnetic array (E1) of the outer case (E) and the magnetic material of the outer accessory (e.g., wireless charger (C)) may overlap each other. The magnetic field sensor (1761) can obtain information (e.g., strength and / or direction) regarding the magnetic field of a portion of the magnetic array (E1) of the outer case (E) and a portion of the magnetic material of the outer accessory (e.g., wireless charger (C)) through the sensing hole (393H). Accordingly, when the electronic device (101) is rotated relative to the outer accessory (e.g., wireless charger (C)), the electronic device (101) can form a magnetic field distribution map of the magnetic material of the outer accessory (e.g., wireless charger (C)) based on the information obtained through the magnetic field sensor (1761).

[0122] According to one embodiment of the present disclosure, the magnetic field distribution formed through the scan mode may be understood as information regarding the magnetic field of a magnetic material included in an external accessory (e.g., wireless charger (C)) distributed along the edge of the wireless charging coil (391) (or along the longitudinal direction of the magnetic array (E1)). Alternatively, the magnetic field distribution formed through the scan mode may be understood as information (strength and / or direction) regarding the magnetic field of a magnetic material included in an external accessory (e.g., wireless charger (C)) distributed along the magnetic array (E1) of the external case (E).

[0123] According to one embodiment of the present disclosure, by forming a magnetic field distribution of a magnetic material included in the external accessory (e.g., wireless charger (C)), the accuracy of the digitizer calibration based on the magnetic field of the magnetic material of the external accessory (e.g., wireless charger (C)) can be improved. By obtaining information on the magnetic field of an external accessory that is not stored in the electronic device (101) through the scan mode, the accuracy of the digitizer calibration can be improved.

[0124] According to one embodiment of the present disclosure, in the scan mode, a gauge (G) and a visual object (P) may be displayed through a display (330) to visually indicate the degree of the scan. The gauge (G) may have a circular loop shape. As the angle at which the electronic device (101) is rotated with respect to the external accessory (e.g., wireless charger (C)) increases, the visual object (P) may expand along the gauge (G). By providing a UI in which the visual (P) expands in correspondence with the rotation angle of the electronic device (101), information regarding the progress of the scan mode may be visually provided to the user.

[0125] FIG. 15 illustrates a wireless charger (C) rotated at a predetermined angle compared to FIG. 13. The description of the wireless charger (C) described below may be applied substantially identically to external accessories including magnetic materials, provided they are not positioned relative to each other.

[0126] Referring to FIG. 15, when a user uses the electronic device (101) or when the electronic device (101) is rotated at a predetermined angle relative to the wireless charger (C) during the operation of the electronic device (101), the magnetic field distribution of the wireless charger (C) in the state of being rotated at the predetermined angle can be obtained based on the magnetic field distribution of the wireless charger (C) formed through the scan mode according to one embodiment of the present disclosure. As an example, if the magnetic field strength (hereinafter, first strength) and direction (hereinafter, first direction) for the first digitizer area (411, see FIG. 10) obtained in a state not rotated by the predetermined angle are the magnetic field strength (hereinafter, second strength) and direction (hereinafter, second direction) for the second digitizer area (412, see FIG. 10), then the magnetic field strength and direction for the first digitizer area (411, see FIG. 10) in the state of being rotated by the predetermined angle can be changed to the second strength and the second direction. Accordingly, for a wireless charger (C) (external accessory) that has already acquired a magnetic field distribution map through the above scan mode, even if the wireless charger (C) is rotated by a predetermined angle and the magnetic field distribution map changes, the previously acquired magnetic field distribution map can be utilized to form a changed magnetic field distribution map without reactivating the above scan mode.

[0127] FIG. 16 is a block diagram of a part of an electronic device (101) according to one embodiment of the present disclosure.

[0128] Referring to FIG. 16, an electronic device (101) according to one embodiment of the present disclosure may include a digitizer module (400).

A plurality of digitizer patterns (411) may be placed on the digitizer panel (410, see FIG. 5). The digitizer patterns (411) may be connected to a battery (189) and configured to form a magnetic field.

[0129] According to one embodiment of the present disclosure, a digitizer module (400) may include a digitizer sensor (420). The digitizer sensor (420) may be connected to a plurality of digitizer patterns (411). The digitizer sensor (420) may be configured to detect current and / or voltage of the plurality of digitizer patterns (411). Voltage and current may be induced in the coil (Q, see FIG. 5) of a stylus (Y, see FIG. 5) by the magnetic field formed by the digitizer pattern (411). The digitizer sensor (420) may be configured to detect a change in the voltage value flowing through the digitizer pattern (411) due to electromagnetic coupling between the digitizer pattern (411) and the coil (Q, see FIG. 5) of the stylus (Y, see FIG. 5). As an example, the processor (120) can calculate the position of the tip (T, see FIG. 5) of the stylus (Y, see FIG. 5) on the digitizer panel (410, see FIG. 5) and / or the display (330) based on a value detected by the digitizer sensor (420).

[0130] According to one embodiment of the present disclosure, an electronic device (101) may include a magnetic field sensor (1761). The magnetic field sensor (1761) may be configured to measure the strength of a magnetic field and / or the direction of a magnetic field.

[0131] According to one embodiment of the present disclosure, the electronic device (101) may include a gyroscope sensor (1762). The gyroscope sensor (1762) may be configured to detect information regarding the rotation of the electronic device (101). As an example, the gyroscope sensor (1762) may be configured to measure the rotation direction and rotation speed of the electronic device (101) with respect to a forward-backward axis (e.g., the Z-axis of FIGS. 2 to 15).

[0132] According to one embodiment of the present disclosure, the battery (189) can be charged by a voltage induced in the wireless charging coil (391) by a wireless charger outside the electronic device (101) (e.g., wireless charger (C) of FIG. 13 to 14).

[0133] According to one embodiment of the present disclosure, an electronic device (101) may include at least one processor (120) and a memory (130) for storing instructions. The instructions stored in the memory (130) may cause the electronic device (101) to perform a predetermined operation (e.g., the digitizer calibration, and / or the scan mode) when executed individually or collectively by at least one processor (120).

[0134] FIG. 17 is a flowchart of a digitizer calibration operation according to one embodiment of the present disclosure.

[0135] Referring to FIGS. 16 and 17, a digitizer calibration operation of an electronic device (101) according to one embodiment of the present disclosure may include an operation (S11) of acquiring information about an external magnetic field using a magnetic field sensor (1761). The information about the external magnetic field may include the strength of the magnetic field and / or the direction of the magnetic field. The electronic device (101) may set a wireless charging protocol based on the measurement value acquired in the external magnetic field information acquisition operation (S11).

[0136] According to one embodiment of the present disclosure, the digitizer calibration operation of the electronic device (101) may include an operation (S12, S13) for determining whether an external accessory is mounted based on the strength of an external magnetic field and the measurement time. The electronic device (101) may determine that an external accessory is mounted if the strength of the magnetic field measured using the magnetic field sensor (1761) (hereinafter, the measured value) is greater than or equal to a reference value and the measured value is measured for a time greater than or equal to a reference duration (hereinafter, the measurement time).

[0137] According to one embodiment of the present disclosure, the digitizer calibration operation of the electronic device (101) according to one embodiment of the present disclosure may include an operation (S14) of calibrating digitizer coordinates based on the measurement value. Digitizer coordinates may be understood as a point on the digitizer panel (410) and / or a point on the display (330). In the digitizer coordinate calibration operation (S14), data of the digitizer sensor (420) corresponding to a point on the digitizer panel (410) and / or a point on the display (330) may be calibrated. Data of the digitizer sensor (420) may be understood as data acquired by the digitizer sensor (420) in response to an external input (e.g., electromagnetic coupling with a stylus (Y)).

[0138] According to one embodiment of the present disclosure, in a digitizer coordinate calibration operation (S14), data of the digitizer sensor (420) can be calibrated based on the strength of the magnetic field detected by the magnetic field sensor (1761). A point on the display (330) calculated based on the data of the digitizer sensor (420) calibrated through the digitizer coordinate calibration operation (S14) can substantially overlap with a region of the digitizer panel (410) that overlaps with the end (T, see FIG. 5) of the stylus (Y).

[0139] According to one embodiment of the present disclosure, in a digitizer coordinate correction operation (S14), the digitizer coordinates can be corrected based on the direction of distortion in each region (331, 332, 333, 334, 335, 336, 337, 338, see FIG. 11) of the display (330). For example, referring to FIG. 11, the image displayed in the plurality of display areas (331, 332, 333, 334, 335, 336, 337, 338) before digitizer calibration can be calibrated so that the digitizer coordinates are closer to the center of the plurality of display areas (331, 332, 333, 334, 335, 336, 337, 338) based on the appearance of being distorted to move away from the center of the plurality of display areas (331, 332, 333, 334, 335, 336, 337, 338).

[0140] According to one embodiment of the present disclosure, after the digitizer coordinate fixing operation (S14), an operation to display an image in a portion of the display (330) calculated based on the corrected data can be performed using the display (330). The image is a graphic element based on the movement and / or tilt of the stylus (Y), and may include points, lines, shapes, etc.

[0141] According to one embodiment of the present disclosure, an electronic device (101) can recognize identification information from the outside. The electronic device (101) can receive identification information for a wireless charger (C, see FIG. 13) from the outside of the electronic device (101) through a wireless charging coil (391) and / or an antenna (392, see FIG. 4). The electronic device (101) can perform an operation (S15) of comparing the recognized identification information with previously stored identification information to determine whether the recognized identification information matches the previously stored identification information.

[0142] According to one embodiment of the present disclosure, in an identification information matching operation (S15), if the recognized identification information matches the previously stored identification information, the electronic device (101) may perform a digitizer coordinate correction operation (S16) based on data corresponding to the previously stored identification information. The description regarding the digitizer coordinate correction operation (S14) based on the measurement value may be applied substantially identically to the digitizer coordinate correction operation (S16) based on the identification information, to the extent that they are not mutually contradictory.

[0143] According to one embodiment of the present disclosure, in a digitizer coordinate correction operation (S16) based on the identification information, if the recognized identification information matches the previously stored identification information and the magnetic field strength measured by the magnetic field sensor (1761) is different from the magnetic field strength corresponding to the previously stored identification information, the data of the digitizer sensor (420) can be corrected based on the difference between the measured magnetic field strength and the previously stored magnetic field strength.

[0144] According to one embodiment of the present disclosure, in an identification information matching operation (S15), if the recognized identification information does not match the previously stored identification information, the electronic device (101) may perform an operation (S17) of activating a scan mode based on user input. In the scan mode activation operation (S17), the electronic device (101) may provide visual information to the user using a display (330). If the electronic device (101) obtains user input in the scan mode activation operation (S17), a scan mode initiation operation (S18) may be performed. The scan mode will be described in detail later with reference to FIG. 18.

[0145] FIG. 18 is a flowchart of the operation sequence of a scan mode according to one embodiment of the present disclosure.

[0146] Referring to FIGS. 16 to 18, according to one embodiment of the present disclosure, the scan mode may include an operation (S21) of acquiring information regarding the rotation of an electronic device (101) using a gyroscope sensor (1762). In the operation of acquiring rotation information (S21), the rotation direction and / or rotation speed of the electronic device (101) may be acquired by the gyroscope sensor (1762). As an example, the gyroscope sensor (1762) may be configured to detect the rotation direction and / or rotation speed of the electronic device (101) rotating with respect to a front-rear axis (e.g., the winding axis of the wireless charging coil (391)).

[0147] According to one embodiment of the present disclosure, the scan mode may include an operation of acquiring data regarding the strength and / or direction of an external magnetic field continuously (sequentially) using a magnetic field sensor (1761) while the electronic device (101) is rotated (while). According to one embodiment of the present disclosure, in the scan mode, data regarding the strength and / or direction of the magnetic field may be acquired through the gyroscope sensor (1762) and the magnetic field sensor (1761) while the electronic device (101) is rotating. As an example, an operation of measuring the strength and direction of the magnetic field may be performed whenever the electronic device (101) is rotated about 5 degrees.

[0148] According to one embodiment of the present disclosure, the scan mode may include an operation (S22) of matching the measured value of the magnetic field sensor (1761) according to the rotation angle of the electronic device (101). In the rotation angle-magnetic field matching operation (S22), each rotation angle of the electronic device (101) (e.g., 5 degrees, 10 degrees, 15 degrees) and the strength of the magnetic field and the direction of the magnetic field matched thereto may be stored in the memory (130). In the rotation angle-magnetic field matching operation (S22), the scan mode UI described with reference to FIG. 14 may be displayed through the display (330).

[0149] According to one embodiment of the present disclosure, the scan mode may include an operation (S23) of correcting digitizer coordinates based on a measurement value matched to each rotation angle. The description of the digitizer coordinate correction operation (S14) based on the measurement value described with reference to FIG. 17 may be applied substantially identically to the digitizer coordinate correction operation (S23) based on the measurement value matched to the rotation angle, to the extent that they are not mutually opposed. In the scan mode-digitizer correction operation (S23), the data of the digitizer sensor (420) for the plurality of digitizer regions (411, 412, 413, 414, 415, 416, 417, 418, see FIG. 10) may be corrected based on the strength and / or direction of the sequentially measured magnetic field.

[0150] According to one embodiment of the present disclosure, in a rotation angle-magnetic field matching operation (S22), identification information corresponding to information regarding rotation angles and the magnetic field matched thereto may be stored in a memory (130). Accordingly, if the identification information recognized through the electronic device (101) after the scan mode corresponds to the identification information stored in the rotation angle-magnetic field matching operation (S22), the data of the digitizer sensor (420) for the plurality of first regions (411, 412, 413, 414, 415, 416, 417, 418) may be corrected based on the rotation angle corresponding to the identification information stored in the rotation angle-magnetic field matching operation (S22) and the strength and / or direction of the magnetic field matched thereto.

[0151] FIG. 19 is a flowchart of the operation when the value detected by the magnetic field sensor (1761) changes, according to one embodiment of the present disclosure.

[0152] Referring to FIGS. 16 and FIGS. 19, an electronic device (101) according to one embodiment of the present disclosure may include an operation (S31) of acquiring information about an external magnetic field using a magnetic field sensor (1761). The description of the operation (S11) of acquiring external magnetic field information described with reference to FIG. 17 may be applied substantially identically to the operation (S31) of acquiring external magnetic field information described with reference to FIG. 19, to the extent that they are not incompatible with each other.

[0153] According to one embodiment of the present disclosure, the electronic device (101) may perform an operation (S32) of detecting a change in the strength of a magnetic field measured through a magnetic field sensor (1761). When a change in the strength of a magnetic field measured through the magnetic field sensor (1761) is detected, the electronic device (101) may perform an operation of obtaining a rate of change in the strength of the magnetic field. As an example, the rate of change in the strength of the magnetic field measured by the magnetic field sensor (1761) may be calculated by a processor (120).

[0154] According to one embodiment of the present disclosure, the electronic device (101) may perform an operation (S33, S34) of comparing the calculated rate of change with a previously stored rate of change (e.g., a threshold rate of change and a limit rate of change). A case where the rate of change of the magnetic field strength is greater than or equal to a first threshold rate of change and less than a second threshold rate of change may be understood as a case where an external accessory previously mounted has been rotated by a predetermined angle or changed to another external accessory.

[0155] According to one embodiment of the present disclosure, the electronic device (101) may include an operation (S35) of determining whether the recognized identification information matches the previously stored identification information when the rate of change of the magnetic field strength detected by the magnetic field sensor (1761) is greater than or equal to a first threshold rate of change and less than a second threshold rate of change, and identification information is recognized from the outside. If the recognized identification information matches the previously stored identification information, the electronic device (101) may perform an operation (S37) of correcting the digitizer coordinates based on the rotation angle of the external accessory. The operation of correcting the digitizer coordinates based on the rotation angle (S37) will be described in detail later with reference to FIG. 20.

[0156] According to one embodiment of the present disclosure, the electronic device (101) may include an operation (S36) of correcting digitizer coordinates based on the measurement value of the magnetic field sensor (1761) if the rate of change of the magnetic field strength detected by the magnetic field sensor (1761) is greater than or equal to a limit rate of change. The electronic device (101) may perform an operation (S36) of correcting digitizer coordinates based on the measurement value of the magnetic field sensor (1761) if the recognized identification information does not match the previously stored identification information. The description of the digitizer coordinate correction operation (S14) based on the measurement value described with reference to FIG. 17 may be applied substantially identically to the digitizer coordinate correction operation (S36) illustrated in FIG. 19 to the extent that they are not mutually opposed.

[0157] FIG. 20 is a flowchart of the operation sequence in which an external accessory is rotated at a predetermined angle after a scan mode, according to one embodiment of the present disclosure. FIG. 20 describes the state after the scan mode as an example, but the operation illustrated in FIG. 20 is not necessarily limited to being performed after the scan mode. As another example, the operation illustrated in FIG. 20 may be performed based on data stored in memory (130).

[0158] Referring to FIGS. 16, 19 and 20, an electronic device (101) according to one embodiment of the present disclosure may perform an operation (S41) of comparing the strength of the magnetic field finally measured by the magnetic field sensor (1761) with the strength of the magnetic field sequentially measured in the scan mode when the rate of change of the magnitude of the magnetic field (M3) detected by the magnetic field sensor (1761) is greater than or equal to a first threshold rate of change and less than a second threshold rate of change. The strength of the magnetic field finally measured may be understood as the strength of the magnetic field acquired last in time by the magnetic field sensor (1761) in the external magnetic field information acquisition operation (S31).

[0159] According to one embodiment of the present disclosure, the electronic device (101) may perform an operation (S42) of detecting (determining) a rotation angle that is matched to one of the magnetic field strengths that is closest to the final measured magnetic field strength among the magnetic field strengths sequentially measured in the scan mode. In the rotation angle detection operation (S42), the electronic device (101) may perform an operation of detecting (determining) a rotation angle that is matched to one of the magnetic field strengths that is closest to the final measured magnetic field strength by comparing the magnetic field strengths stored in the memory (130), rather than the magnetic field strengths measured in the scan mode, with the magnetic field strengths that are closest to the final measured magnetic field strength.

[0160] According to one embodiment of the present disclosure, the electronic device (101) can change the rotation angle matched to the magnetic field strengths sequentially measured in the scan mode based on the detected rotation angle. As an example, if the magnetic field strength matched to a rotation angle of 5 degrees is 7 mT, the magnetic field strength matched to a rotation angle of 10 degrees is 8 mT, and the detected rotation angle is 5 degrees, the magnetic field strength matched to a rotation angle of 10 degrees can be changed from 8 mT to 7 mT.

[0161] According to one embodiment of the present disclosure, the electronic device (101) may include an operation (S43) for correcting digitizer coordinates based on the rotation angle detected in the rotation angle detection operation (S42). The description of the digitizer coordinate correction operation (S23) based on the measurement value matched to the rotation angle described with reference to FIG. 18 may be applied substantially identically to the digitizer coordinate correction operation (S43) based on the rotation angle detected in a range that is not mutually conflicting. Based on the strength of the magnetic field matched to the rotation angle changed based on the rotation angle detected in the rotation angle detection operation (S42), the data of the digitizer sensor (420) for the plurality of digitizer regions (411, 412, 413, 414, 415, 416, 417, 418, see FIG. 10) may be corrected.

[0162] An electronic device may include a digitizer module for detecting the position or tilt of a stylus via electromagnetic induction. Meanwhile, the electronic device may be equipped with various types of external accessories containing magnetic materials. In the case of electronic devices made of metal, external accessories containing magnetic materials can be mounted, eliminating the need for separate connecting or adhesive components. However, the digitizer may be affected by the magnetic field of the magnets included in the external accessories. For example, interference with magnetic field detection by the digitizer module may result in inaccurate calculation of the stylus's position on the display. Accordingly, much research is being conducted to reduce operational errors in the digitizer module when various external accessories are mounted.

[0163] The problem to be solved in the present disclosure may be to improve the operation error of a digitizer module caused by the magnetic field of an external accessory.

[0164] However, the problems to be solved in this disclosure are not limited to those mentioned above, and may be determined in various ways without departing from the spirit and scope of this disclosure.
