Title: Electronic device and method for correcting geomagnetic data

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a by-pass continuation application of International Application No. PCT/KR2021/008375, filed on Jul. 1, 2021, which based on and claims priority to Korean Patent Application No. 10-2020-0081629, filed on Jul. 2, 2020, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference herein in their entireties. 
    
    
     BACKGROUND 
     1. Field 
     The disclosure relates to an electronic device and a method for improving accuracy of data through correction of a magnetic sensor. 
     2. Description of Related Art 
     Recently, in line with a significant increase in processing performance of electronic devices such as smartphones, large-area displays are preferred in order to effectively provide various functions. In addition, miniaturization of electronic devices is also required to improve portability. 
     In response to these demands, an electronic device employing a rollable display is able to provide both a wide screen and portability. When a portion of the display is rolled into the electronic device such that the display is reduced, it is possible to secure portability and provide a wide screen when the display is expanded. 
     Recent electronic devices are often equipped with a geomagnetic sensor for providing azimuth information. However, the accuracy of the geomagnetic sensor may be lowered depending on the surrounding environment, so a calibration of the geomagnetic sensor is required to obtain accurate azimuth information. For example, an application that mainly uses the geomagnetic sensor may provide a User Interface (UI) requesting the user to move the device in a circle or figure eight shape, thereby perform calibration. 
     Assuming a scenario in which a user utilizes a geomagnetic sensor in a rollable electronic device, the user must extend the rollable electronic device and then perform an operation to move the rollable electronic device in a circle or in a figure eight (8). However, since the extended electronic device has a large size, it is not convenient for the user to move the electronic device, and the user is likely to drop the electronic device, causing a risk of falling or damage. 
     Although existing electronic devices are capable of using geomagnetic data in two operations of executing an app and correcting sensor data, a rollable electronic device may require three operations such as executing an app, expanding a device, and correcting sensor data. 
     SUMMARY 
     According to an aspect of the disclosure, an electronic device includes: a housing having a first housing and a second housing coupled to the first housing to be movable relative to the first housing; a roller part; a drive part connected to the roller part; a rollable display having (i) a first part disposed adjacent to the second housing, and (ii) a second part surrounding the roller part and having a portion disposed inside the electronic device; a magnetic sensor disposed at a position corresponding to the second part; and at least one processor configured to electrically connect to the magnetic sensor. The magnetic sensor is disposed at a first position in the second housing coupled with the first housing in a first state. The magnetic sensor is configured to move from the first position to a second position based on a movement of the second housing in the first state relative to the first housing so that the first housing and the second housing are coupled in a second state. The magnetic sensor is configured to move from the second position to the first position based on a switching from the second state to the first state. The at least one processor is further configured to: obtain geomagnetic data based on a movement of the magnetic sensor; and obtain correction data based on the obtained geomagnetic data. 
     According to another aspect of the disclosure, a method of correcting geomagnetic data of an electronic device having a rollable display and a magnetic sensor, includes: arranging the magnetic sensor at a first position in a second housing coupled with a first housing, the magnetic sensor being movable from the first position to a second position; obtaining geomagnetic data from the magnetic sensor based on a movement of the second housing relative to the first housing, the movement of the second housing changing an area where the rollable display is exposed to the outside of the electronic device; and obtaining correction data based on the obtained geomagnetic data. 
     According to one or more embodiments of the disclosure, in an electronic device having a rollable structure, a change in the coupling structure of the device may be detected, and one or more movements occurring at this time may be used to calibrate a geomagnetic sensor to correct geomagnetic sensor data when switching between the coupling structures, thereby improving accuracy. 
     In addition, it is possible to provide corrected geomagnetic data according to a user&#39;s request without additional operations of the user. Effects obtained from one or more embodiments of the disclosure are not limited to the above-mentioned effects, and other effects not mentioned above will be clearly understood by those of ordinary skill in the art to which the disclosure belongs from the description below.

       FIG.  1 A  is a front perspective view of an electronic device in a first state according to an embodiment.  FIG.  1 B  is a front perspective view of an electronic device in a second state according to an embodiment. 
     Referring to  FIGS.  1 A and  1 B , the electronic device  100  according to an embodiment may have a display  120  positioned on one surface. Hereinafter, the surface on which the display  120  is positioned will be referred to as a ‘front surface.’ According to an embodiment, the display  120  may occupy most of the front surface of the electronic device  100 . According to an embodiment, the display  120  may include a flat shape and a curved shape. The display  120  and the housing  110  surrounding at least a portion of an edge of the display  120  may be disposed on the front surface of the electronic device  100 . According to an embodiment, the housing  110  may form a partial area of the front surface, a side surface, and a rear surface of the electronic device  100 . According to another embodiment, the housing  110  may form a partial area of a side surface and a rear surface of the electronic device  100 . According to an embodiment, the housing  110  may include a first housing  111  and a second housing  112  that is movable relative to the first housing  111 . 
     According to an embodiment, the display  120  may include a first part  121  that may be coupled to the second housing  112 , and a second part  122  that extends from the first part  121  and may be received inside the electronic device  100 . According to an embodiment, if the electronic device  100  switches from the first state  100   a  to the second state  100   b  according to the movement of the second housing  112 , the second part  122  of the display  120  may be drawn out of the electronic device  100 . According to an embodiment, if the electronic device  100  switches from the second state  100   b  to the first state  100   a  according to the movement of the second housing  112 , the second part  122  of the display  120  may be received inside the electronic device  100 . 
       FIG.  2 A  is a cross-section view of an electronic device in a first state according to an embodiment.  FIG.  2 B  is a cross-section view of an electronic device in a second state according to an embodiment. 
     Referring to  FIGS.  2 A and  2 B , an electronic device  100  according to an embodiment may include a display  120 , a first housing  111 , a second housing  112 , a roller part  130 , a rolling rail  160 , a magnetic sensor  140 , a Printed Circuit Board (PCB)  211 , a Flexible PCB (FPCB)  212 , and a structure detection sensor  150 . The elements of the electronic device  100  illustrated in  FIGS.  2 A and  2 B  are only examples for convenience of description, and other elements may be added thereto, or at least some of the illustrated elements may be excluded or modified. 
     Referring to  FIGS.  2 A and  2 B , the display  120  may be disposed on the front surface of the electronic device  100  according to an embodiment. According to an embodiment, the roller part  130  may be disposed inside the electronic device  100 . According to an embodiment, the rolling rail  160  may be coupled to the display  120 . The rolling rail  160  may be disposed to surround the roller part  130 . According to an embodiment, the rolling rail  160  may move along with the display  120  while surrounding the roller part  130  according to the movement of the second housing  112 . 
     According to an embodiment, the roller part  130  may include elements capable of providing rotational motion. For example, it may include a shaft configuring a rotation shaft and a gear structure. 
     According to an embodiment, if the electronic device  100  switches from the first state  100   a  to the second state  100   b , the second part  122  of the display  120  may be exposed to the outside of the electronic device  100  according to the movement of the rolling rail  160 . According to another embodiment, if the electronic device  100  switches from the second state  100   b  to the first state  100   a , the second part  122  of the display  120  may be received inside the electronic device  100  while surrounding the roller part  130  according to the movement of the rolling rail  160 . 
     The magnetic sensor  140  according to an embodiment may include, but is not limited to, a geomagnetic sensor, the Hall sensor, and a compass sensor. 
     According to an embodiment, the magnetic sensor  140  may be disposed adjacent to the display  120  on the rolling rail  160 . According to another embodiment, the magnetic sensor  140  may be disposed on one surface adjacent to the rolling rail  160  of the display  120 . According to an embodiment, the magnetic sensor  140  may be disposed inside the rolling rail  160  so as to be adjacent to the display  120 . According to another embodiment, the magnetic sensor  140  may be disposed inside the rolling rail  160  so as to be adjacent to the roller part  130 . According to an embodiment, a printed circuit board  211  may be disposed in the electronic device  100 . For example, the magnetic sensor  140  may be disposed on the printed circuit board  211  or may be electrically connected to the printed circuit board  211 . According to an embodiment, the magnetic sensor  140  may be electrically connected to the printed circuit board  211  and the FPCB  212 . 
     In an embodiment, as the state of the electronic device  100  changes, the magnetic sensor  140  may move around the roller part  130  together with the display  120 . For example, the magnetic sensor  140  may be disposed adjacent to the rear surface of the electronic device  100  in the first state  100   a  but may be disposed adjacent to the front surface of the electronic device  100  in the second state  100   b . In an embodiment, the magnetic sensor  140  may be turned upside down when moving around the roller part  130 . For example, the upper surface  140   a  (e.g., the surface facing the display  120 ) of the magnetic sensor  140  may face the rear surface of the electronic device  100  in the first state  100   a  and face the front surface of the electronic device  100  in the second state  100   b . According to an embodiment, as the display screen of the electronic device  100  expands, the magnetic sensor  140  may move relative to the electronic device  100  along a straight path having a first length, and move along a curved path around the roller part  130 , and then move along a straight path having a second length. Here, if it is assumed that the magnetic sensor moves in a first direction when moving the first length, the magnetic sensor may move in the opposite direction of the first direction when moving the second length. Alternatively or in addition, the first length may be the same as or different from the second length depending on design. 
     According to another embodiment, as the state of the electronic device  100  changes, the magnetic sensor  140  may move in the direction of movement of the second housing  112  in the area corresponding to the second part  122  of the display  120  of the electronic device  100 . 
     According to an embodiment, the structure detection sensor  150  may be disposed in a part of the housing  110  or inside the housing  110  to detect a change in the structure of the housing  110 . The structure detection sensor  150  may include, for example, at least one of the Hall sensor and a distance sensor, but is not limited thereto. For example, it may include at least one of an optical distance sensor, an ultrasonic distance sensor, and a radio wave distance sensor capable of detecting the state of the housing  110  or the movement distance of the housing  110 . 
     According to an embodiment, if the electronic device  100  switches from the first state  100   a  to the second state  100   b  or from the second state  100   b  to the first state  100   a , the structure detection sensor  150  may detect a change in the state of the electronic device  100 . For example, the structure detection sensor  150  may detect that a state change is started, that a state change is in progress, or that a state change is completed. For example, the Hall sensor may be a magnetic sensor and may be disposed in a part of the housing  110  or inside the housing  110  to detect a change in magnetism according to the movement of the housing  110 , thereby detecting a change in the state of the housing  110 . The disposition of the structure detection sensor  150  is not limited to the inside or part of the housing, and it may be disposed inside the electronic device  100 . According to an embodiment, it is possible to measure a distance between a first point of the first housing  111  and a second point of the second housing  112 , thereby detecting a change in state of the electronic device  100  according to a change in the distance. For example, a distance sensor may measure distance by emitting light or radio waves and using the time it takes for the light or radio waves to be reflected from other objects and come back. For example, the distance sensor may include a Time-Of-Flight (TOF) sensor that is an optical distance sensor. The TOF sensor may further include a light-emitting unit and measure the time it takes for the light emitted from the light-emitting unit to be reflected from other objects and come back, thereby measuring a distance. For example, the light-emitting unit of the TOF sensor may be disposed in a part of the housing  110  or inside the housing  110  to be spaced apart from the TOF sensor. 
     According to an embodiment, the structure detection sensor  150  may be disposed on a printed circuit board disposed inside the housing  110  or may be electrically connected to the printed circuit board. However, those skilled in the art will readily understand that disposition of the structure detection sensor  150  is not limited and that any disposition capable of detecting the state change, according to one or more embodiments of the disclosure, may be applied. 
       FIG.  3 A  is a cross-section view of an electronic device including a plurality of joint structures in a first state according to an embodiment.  FIG.  3 B  is a cross-section view of an electronic device including a plurality of joint structures in a second state according to an embodiment. 
       FIGS.  3 A and  3 B  are cross-sectional views of the electronic device  300  in which some configurations of the electronic device  300  are omitted in order to explain the movement of the housing  110  in the first state  300   a  and the second state  300   b.    
     Referring to  FIGS.  3 A and  3 B , an electronic device  300  according to an embodiment may include a display  120 , a first housing  111 , a second housing  112 , a roller part  130 , a rolling rail  160 , a magnetic sensor  140 , and/or a structure detection sensor  150 . According to an embodiment, the electronic device  300  may include at least one spring inside the electronic device  300 . According to another embodiment, at least one (e.g., at least one spring) of the above-described elements of the electronic device  300  may be omitted or other elements may be added thereto. The same reference numerals will be used for the same or the substantially same elements as those described above, and redundant descriptions will be omitted. 
     According to an embodiment, the first housing  111  may form at least a portion of a side surface and/or a rear surface of the electronic device  300 . According to an embodiment, the second housing  112  may form at least a portion of a front surface and/or a side surface of the electronic device  300 . According to an embodiment, the display  120  may be coupled to at least a portion of the second housing  112 . 
     According to an embodiment, a partial area of the display  120  may be disposed to overlap the second housing  112 . For example, at least a partial area of one surface of the display  120  may be disposed to come into contact with at least a partial area of the front surface of the second housing  112 , and the opposite surface of the second housing  112  may be disposed to be exposed to the outside. 
     According to an embodiment, the rolling rail  160  may include a plurality of joint structures  161  and a support plate  162 . In an example, a partial area of the plurality of joint structures  161  may be deformed in its shape while the state (e.g., the first state  300   a  or the second state  300   b ) of the electronic device  300  switches. For example, a partial area of the plurality of joint structures  161  may be bent to have a specified curvature or unfolded when the electronic device  300  switches from the first state  300   a  to the second state  300   b  or from the second state  300   b  to the first state  300   a . According to another embodiment, the second housing  112  may be fixed or coupled to one end of the plurality of joint structures  161 , and a portion of the first part  121  of the display  120  may be disposed at the upper end of the second housing  112 . In another example, the support plate  162  may be fixed or coupled to one end of the plurality of joint structures  161 . 
     According to an embodiment, the roller part  130  may include a first roller  130   a  and/or a second roller  130   b  disposed to be spaced apart from the first roller  130   a . For example, the second housing  112  of the display  120  may be coupled to one end of the second roller  130   b . Accordingly, the above-described second roller  130   b  may serve to maintain the flatness of the display  120  when the electronic device  300  switches from the second state  300   b  to the first state  300   a  or from the first state  300   a  to the second state  300   b . According to an embodiment, the first roller  130   a  may include elements (e.g., a rotation shaft and a gear) that provides rotational motion. Additionally, the first roller  130   a  may further include a motor connected to at least one (e.g., a rotation shaft) of the elements. 
     According to an embodiment, the first roller  130   a  may come into contact with the plurality of joint structures  161  of the rolling rail  160 , and the rolling rail  160  may move within a specified range by rotation of the first roller  130   a . For example, if the first roller  130   a  rotates clockwise while the electronic device  300  is switching from the first state  300   a  to the second state  300   b , a partial area of the plurality of joint structures  161 , which is in the bent state, may become flat so that the rolling rail  160  may move in a first direction (e.g., a direction away from the first roller  130   a ). As another example, if the first roller  130   a  rotates counterclockwise while the electronic device  300  is switching from the second state  300   b  to the first state  300   a , a partial area of the plurality of joint structures  161 , which is in the flat state, may be bent so that the rolling rail  160  may move in a second direction (e.g., the opposite direction of the first direction). According to an embodiment, as the shape of the partial area of the plurality of joint structures  161  is deformed when the state of the electronic device  300  switches, the shape of the second part  122  of the display  120 , supported by the plurality of joint structures  161 , may also be deformed to correspond to the shape of the plurality of joint structures  161 . 
     According to an embodiment, the display  120  may be disposed on the outer circumferential surface of the rolling rail  160 , and the above-described display  120  may move together with the rolling rail  160  by the rotation of the first roller  130   a . According to an embodiment, the display  120  may include a first part  121  and/or a second part  122  whose shape may be deformed according to the state of the electronic device  300 . 
     According to an embodiment, the first part  121  of the display  120  may be located at the upper end of the second housing  112  of the rolling rail  160  and/or the partial area of the plurality of joint structures  161  to be supported by the second housing  112  and/or the plurality of joint structures  161 . In an example, the first part  121  of the display  120  may be exposed to the outside of the electronic device  300  regardless of the state of the electronic device  300  (e.g., the first state  300   a  or the second state  300   b ). 
     According to an embodiment, the second part  122  of the display  120  may be located at the upper end of the partial area of the plurality of joint structures  161  of the rolling rail  160  to be supported by the plurality of joint structures  161 . In an example, the second part  122  of the display  120  may be selectively exposed to the outside of the electronic device  300  depending on the state of the electronic device  300 . 
     For example, when the electronic device  300  is in the first state  300   a , the second part  122  of the display  120  may be received in the inner space of the electronic device  300  while being wound around the plurality of joint structures  161 , and as a result, the second part  122  may not be exposed to the outside of the electronic device  300 . As another example, if the electronic device  300  switches from the first state  300   a  to the second state  300   b , the area of the second part  122  of the display  120 , which is adjacent to the first part  121 , may be drawn out of the electronic device  300 . As the partial area of the second part  122  adjacent to the first part  121  is drawn out of the electronic device  300 , the area of the display  120  exposed to the outside of the electronic device  300  may be expanded. As another example, if the electronic device  300  switches from the second state  300   b  to the first state  300   a , the area of the second part  122  exposed to the outside of the electronic device  300 , which is adjacent to the support plate  162 , may be received inside the electronic device  300 . As the partial area of the second part  122  adjacent to the support plate  162  is received inside the electronic device  300 , the area of the display  120  exposed to the outside of the electronic device  300  may be reduced. 
     The electronic device  300  according to one or more embodiments is not limited to the configuration illustrated in  FIGS.  2 A to  3 B . For example, the display  120  may be disposed to surround most of the front surface and a part of the rear surface of the electronic device  300 , so that the partial area of the display  120  may be exposed to the outside through the rear surface of the electronic device  300  even in the first state  300   a.

According to an embodiment, the first spring  511  and/or the second spring  512  may move in a second direction opposite the first direction to reduce the pressure applied to the part of the housing  110 . Accordingly, the part of the housing  110  may move so that the electronic device  100  may switch from the second state  100   b  to the first state  100   a.    
     According to an embodiment, the magnetic sensor  140  may be disposed on one surface of the first spring  511  or the second spring  512 . According to an embodiment, the magnetic sensor  140  may move in the same direction as the movement direction of the spring  510  according to the movement of the spring  510 . 
     According to an embodiment, in the case where the first spring  511  or the second spring  512  each includes a plurality of spring structures, it is possible to apply pressure to a part of the housing  110  using the repulsive force between the plurality of spring structures. Accordingly, as the part of the housing  110  moves, the electronic device  100  may switch from the first state  100   a  to the second state  100   b . For example, the repulsive force between the plurality of spring structures may be generated by at least one of a magnet, an electrical signal, and a physical coupling structure.

     According to an embodiment, a sphere equation (e.g., the above-described Equation 1) may be estimated using the obtained geomagnetic data. However, the equation estimated using the geomagnetic data is not limited to the sphere equation and may include an equation having a plurality of variables.
