Description

METHOD FOR DISPLAYING SCREEN IN ELECTRONIC DEVICE AND ELECTRONIC DEVICE THEREOF

The present disclosure relates to a technology for displaying a screen of an electronic device.

The cover of an electronic device such as a smartphone, a tablet personal computer (PC), or the like may be used to safely protect the electronic device from external shock. Also, the cover has been recently used as an accessory that expresses the personality of a user. In addition, with the development of a technology for implementing various functions of the electronic device, a technology for implementing various functions with the cover has been developed.

The electronic device may include a connector that connects the electronic device to the cover, and may determine whether the cover is mounted, based on a voltage level of a specific terminal of the connector. The opening/closing state of the cover after the cover is mounted may be determined by using a hall effect integrated circuit (IC) that determines whether a magnet located in the cover approaches the electronic device.

To address the above-discussed deficiencies, it is a primary object to provide an electronic device that may include a connector for determining whether an accessory is mounted, and may include a general purpose input output (GPIO) or an analog digital converter (ADC) port capable of determining the electrical state of the terminal of the connector. In addition, the electronic device may include a hall effect IC and the GPIO to determine the opening/closing state of the cover. At this time, the electronic device determines the opening/closing state of the cover. However, since it is not determined how the electronic device is mounted on the cover, it is difficult to provide a user-friendly environment in a mounted state.

According to various embodiments of the present disclosure, an electronic device may recognize the mounted state of a cover and perform an operation according to the state of the cover.

In accordance with an aspect of the present disclosure, an electronic device from which an accessory including at least one magnet is removable may include a housing of the electronic device including a front housing capable of being covered by at least part of the accessory and a rear housing from which at least other part of the accessory is removable, a display exposed through at least part of the front housing, an electromagnetic induction panel disposed inside the housing, including a first channel group corresponding to a first direction and a second channel group corresponding to a second direction perpendicular to the first direction, and sensing a first signal flowing into the first channel group and a second signal flowing into the second channel group, and a processor disposed inside the housing and electrically connected to the electromagnetic induction panel. The processor may be configured, if a combination of at least one first channel, in which it is sensed that a magnitude of the first signal is not greater than a first critical value, in the first channel group and at least one second channel, in which it is sensed that a magnitude of the second signal is not greater than a second critical value, in the second channel group corresponds to one of predefined channel combinations, to perform a preset operation.

In accordance with an aspect of the present disclosure, a method of an electronic device is provided. The method includes sensing that a magnitude of a first signal is not greater than a first critical value, sensing that a magnitude of a second signal is not greater than a second critical value, and if a combination of at least one first channel in a first channel group of an electromagnetic induction panel and at least one second channel in a second channel group of the electromagnetic induction panel corresponds to one of predefined channel combinations, performing a preset operation.

In accordance with an aspect of the present disclosure, an electronic device from which an accessory including at least one magnet is removable may include a housing of the electronic device including a front housing covered by the accessory, a display exposed through at least part of the front housing, an electromagnetic induction panel disposed inside the housing, including a first channel group corresponding to a first direction and a second channel group corresponding to a second direction perpendicular to the first direction, and sensing a first signal flowing into the first channel group and a second signal flowing into the second channel group, and a processor disposed inside the housing and electrically connected to the electromagnetic induction panel. The processor may be configured, if a combination of at least one first channel, in which it is sensed that a magnitude of the first signal is not greater than a first critical value, in the first channel group and at least one second channel, in which it is sensed that a magnitude of the second signal is not greater than a second critical value, in the second channel group corresponds to one of predefined channel combinations, to perform a preset operation.

In accordance with an aspect of the present disclosure, an electronic device coupled to an accessory may include the accessory covering at least part of a housing of the electronic device and including at least one magnet, the housing of the electronic device including a front housing, a display exposed through at least part of the front housing, an electromagnetic induction panel disposed inside the housing, including a first channel group corresponding to a first direction and a second channel group corresponding to a second direction perpendicular to the first direction, wherein a magnitude of a first signal flowing into the first channel group and a magnitude of a second signal flowing into the second channel group are reduced due to a magnetic field applied by the magnet, and a processor disposed inside the housing and electrically connected to the electromagnetic induction panel. The processor may be configured, if a combination of at least one first channel, in which a magnitude of the first signal is not greater than a first critical value, in the first channel group and at least one second channel, in which a magnitude of the second signal is not greater than a second critical value, in the second channel group corresponds to one of predefined channel combinations, to perform a preset operation.

According to various embodiments disclosed in the present disclosure, an electronic device may recognize whether an accessory using a magnet is mounted, or the state of an accessory, by using an electromagnetic induction panel, thus providing a user with a convenient usage environment.

In addition, since an electronic device according to an embodiment of the present disclosure does not connect to an accessory electrically and does not use a hall effect IC, a cost to produce the electronic device may be saved.

FIG. 1 illustrates a view of a cover, according to an embodiment of the present disclosure.

Referring to FIG. 1, a cover 110 according to an embodiment of the present disclosure may include at least one

magnet

111a, 112a, or 112b, and may include a back cover 111 and a front cover 112.

The back cover 111 may be removable from the rear housing of an electronic device and may include the at least one magnet 111a. The back cover 111 may be attached to the rear housing by the magnetic force of the magnet 111a.

The front cover 112 may cover the front housing of the electronic device and may include the at least one

magnet

112a or 112b. As illustrated in FIG. 1, the front cover 112 may include the first magnet 112a and the second magnet 112b.

The first magnet 112a may be used to recognize the opening/closing of the front cover 112. In addition, the second magnet 112b may attach the front cover 112 to the front housing and may be used to mount the electronic device that is coupled to the cover 110. For example, the front cover 112 is bended at at least one point and a part of the front cover 112 is attached to the back cover 111 by the magnetic force of the second magnet 112b, and then, as illustrated in FIG. 7a and 8a, the front cover 112 may mount the electronic device.

FIG. 2 illustrates a view of an outer appearance of an electronic device, according to an embodiment of the present disclosure.

Referring to FIG. 2, an electronic device 200 according to an embodiment may include a housing 210, an electromagnetic induction panel 220, a display 230, a processor (not illustrated), and the like.

The housing 210 may include a rear housing 211 and a front housing 212. A back cover such as the back cover as illustrated in FIG. 1 may be attached to the rear housing 211, and the front housing 212 may be covered by the front cover such as the front cover as illustrated in FIG. 1.

The electromagnetic induction panel 220 may not be exposed in the outer appearance of the electronic device 200. However, the electromagnetic induction panel 220 may be disposed inside the housing 210 and may be disposed parallel to the display 230.

The display 230 may be exposed through at least part of the front housing 212.

The processor may not be exposed in the outer appearance of the electronic device 200. However, the processor may be electrically connected to the electromagnetic induction panel 220 and the display 230 and may be disposed inside the housing 210.

Hereinafter, a configuration in which an electronic device 300 according to an embodiment of the present disclosure is included will be described with reference to FIGS. 3a and 3b.

FIG. 3a illustrates a view of an electronic device to which a magnetic field of a pen input device is applied, according to an embodiment of the present disclosure. FIG. 3b illustrates a view of a circuit diagram of an electromagnetic induction panel, according to an embodiment of the present disclosure.

Referring to FIG. 3a, the electronic device 300 according to various embodiments of the present disclosure may include an electromagnetic induction panel 320, a display 330, a processor 340, and the like. An electromagnetic induction panel pad 321 and the display 330 may be stacked. The electromagnetic induction panel 320 and the display 330 may correspond to the electromagnetic induction panel 220 and the display 230 of FIG. 2, respectively.

The electromagnetic induction panel 320 may include the electromagnetic induction panel pad 321 and an electromagnetic induction panel controller 322.

Referring to FIG. 3b, the electromagnetic induction panel pad 321 may include a plurality of loop antenna coils overlapped with each other in a first direction (e.g., a landscape mode) and in a second direction (e.g., a portrait mode) perpendicular to the first direction and may generate an electromagnetic field. One antenna coil may constitute one channel, or a plurality of antenna coils may constitute one channel. That is, the electromagnetic induction panel pad 321 may include a first channel group 321a corresponding to the first direction and a second channel group 321b corresponding to the second direction perpendicular to the first direction. In addition, the electromagnetic induction panel pad 321 may include a shield plate (not illustrated) for shielding a noise, on one surface.

The electromagnetic induction panel controller 322 may sense a signal that flows into the first channel group 321a and the second channel group 321b to detect the location of a pen input device 350; the electromagnetic induction panel controller 322 may provide the processor 340 with the detection location as coordinates at which the pen input device 350 is recognized.

If the pen input device 350 contacts or approaches the electromagnetic field of the electromagnetic induction panel pad 321, a resonance circuit unit of the pen input device 350 may generate a current, and then a magnetic field may be formed by the current. The magnitude of a signal that flows into at least one first channel of the first channel group 321a and at least one second channel of the second channel group 321b may be changed by the formed magnetic field. The electromagnetic induction panel controller 322 may detect a location, at which the first channel and the second channel, in each of which the magnitude of the signal is changed, intersect each other, as the location of the pen input device 350. For example, if the pen input device 350 approaches the electromagnetic induction panel pad 321, the magnitude of the signal flowing into the first channel and the second channel corresponding to a location that the pen input device 350 approaches may increase.

Meanwhile, the magnitude of the signal flowing into the first channel group 321a and the second channel group 321b of the electromagnetic induction panel pad 321 may decrease by applying a magnetic field of a magnet. As in the detection of the location of the pen input device 350, the electromagnetic induction panel controller 322 may sense the magnitude of the signal flowing into the first channel group 321a and the second channel group 321b and may detect the location of a magnet that contacts or approaches the electromagnetic field of the electromagnetic induction panel pad 321. For example, if the magnet approaches the electromagnetic induction panel pad 321, the magnitude of the signal flowing into the first channel and the second channel corresponding to a location that the magnet approaches may decrease.

The display 330 may output a screen generated by the processor 340.

If a combination of at least one first channel, in which it is sensed that the magnitude of the signal is not greater than a first critical value, in the first channel group 321a and at least one second channel, in which it is sensed that the magnitude of the signal is not greater than a second critical value, in the second channel group 321b corresponds to one of predefined channel combinations, the processor 340 may be configured to perform a preset operation. The operation performed by the processor 340 may include an operation of changing a screen displayed in the display 330, an operation of sensing that an accessory is attached to the electronic device 300, an operation of adjusting power consumed by the processor, or the like.

Furthermore, the processor 340 may be configured to sense a type of the attached accessory based on a combination of the first channel and at least one second channel.

The processor 340 may be configured to apply a correction value to a location of the pen input device 350, which is sensed by the electromagnetic induction panel 320, based on the combination of the first channel and at least one second channel.

FIG. 3c illustrates a flowchart of a method in which a processor performs a preset operation, according to an embodiment of the present disclosure.

In operation 301, an electromagnetic induction panel senses the magnitude of a signal flowing into a first channel group and a second channel group. The electromagnetic induction panel may sense the magnitude of a signal flowing into each of channels included in the first channel group and the second channel group.

In operation 303, the processor may determine whether the magnitude of a signal flowing into a preset channel is less than a critical value. In an embodiment, the preset channel may be a combination of a channel included in the first channel group and a channel included in the second channel group. The critical value may include a plurality of values.

In the case where the magnitude of the signal flowing into the preset channel is less than a critical value, in operation 305, the processor may perform a preset operation. In an embodiment, the processor may perform an operation based on the combination of channels into which the signal, the magnitude of which is not greater than the critical value, flows.

Hereinafter, the detailed operation of the processor for each state of an accessory will be described with reference to FIGS. 4a to 12b.

The operation of the processor in a state where the accessory is attached to a housing will be exemplified with reference to FIGS. 4a to 5b.

In the specification, it is assumed that the accessory to be mounted in the electronic device is a cover. However, the accessory to which the present disclosure is capable of being applied is not limited to a cover.

FIG. 4a illustrates a view of how a cover is attached to an electronic device 400, according to an embodiment of the present disclosure. FIG. 4b illustrates a view of a channel in which it is sensed, by an electromagnetic induction panel of the electronic device 400 illustrated in FIG. 4a, that a magnitude of a signal is not greater than a critical value, according to an embodiment of the present disclosure.

In this embodiment, it is assumed that a predefined channel combination allowing a processor to sense that a cover is attached to an electronic device 400 includes a combination of channels A, B, and C 421a as a first channel and channels D and E 421b as a second channel.

As illustrated in FIG. 4a, if a back cover 411 is attached to the rear housing of the electronic device 400, a plurality of magnets 411a included in the back cover 411 may apply a magnetic field to a cover 410. As such, the magnitude of a signal flowing into the first channel and the second channel corresponding to locations of the plurality of magnets 411a may decrease.

According to an embodiment of the present disclosure, as illustrated in FIG. 4b, it may be sensed that the magnitude of a signal of each of the channels A, B, and C 421a in the first channel group is not greater than a first critical value, by using to the magnets 411a of the back cover 411; it may be sensed that the magnitude of a signal of each of the channels D and E 421b in the second channel group is not greater than a second critical value, by using the magnets 411a of the back cover 411. That is, points at which channels A, B, and C are intersected with channels D and E may correspond to the locations of the magnets 411a of the back cover 411.

Since a combination of the channels A, B, and C 421a, in which it is sensed that the magnitude of the signal is not greater than the first critical value, and the channels D and E 421b, in which it is sensed that the magnitude of the signal is not greater than the second critical value is included in the above-described predefined channel combination, the processor may sense that the cover is attached to the electronic device 400.

FIG. 5a illustrates a view of how a cover different from a cover of FIG. 4a is attached to an electronic device 500, according to an embodiment of the present disclosure. FIG. 5b illustrates a view of a channel in which it is sensed, by an electromagnetic induction panel of the electronic device 500 illustrated in FIG. 5a, that a magnitude of a signal is not greater than a critical value, according to an embodiment of the present disclosure.

In this embodiment, it is assumed that a predefined channel combination allowing a processor to sense that a cover is attached to the electronic device 500 includes a combination of channels A and C 521a as a first channel and channels D and E 521b as a second channel.

As in descriptions given with reference to FIGS. 4a and 4b, since a combination of the channels A and C, in which it is sensed that the magnitude of the signal is not greater than a first critical value, and channels D and E, in which it is sensed that the magnitude of the signal is not greater than a second critical value is included in the above-described predefined channel combination, the processor may sense that the cover is attached to the electronic device 500.

Meanwhile, a type of the cover 410 of FIG. 4 may be different from a type of a cover 510 of FIG. 5a, and the placement of

magnets

411a or 511a included in the

back cover

411 or 511 of the covers 410 or 510 may be different from each other. The processor may sense a type of the cover attached to a rear housing, based on a combination of the at least one

first channel

421a or 521a, in which it is sensed that the magnitude of a signal is not greater than the first critical value, in the first channel group, and the at least one

second channel

421b or 521b, in which it is sensed that the magnitude of a signal is not greater than the second critical value, in the second channel group.

For example, in the case where the

first channel

421a or 521a in which it is sensed that the magnitude of a signal is not greater than the first critical value, is channels A, B, and C, and the

second channel

421b or 521b in which it is sensed that the magnitude of a signal is not greater than the second critical value, is channels D and E, the processor may sense that the cover 410 of FIG. 4a is attached to the electronic device 400. In addition, in the case where the first channel in which it is sensed that the magnitude of a signal is not greater than the first critical value, is one of the channels A and C 521a, and the second channel in which it is sensed that the magnitude of a signal is not greater than the second critical value, is one of the channels D and E 521b, the processor may sense that the cover 510 of FIG. 5a is attached to the electronic device 500.

The operation of the processor in a state where a cover covers a front housing will be exemplified with reference to FIGS. 6a and 6b.

FIG. 6a illustrates a view of how a cover covers a front housing of an electronic device 600, according to an embodiment of the present disclosure. FIG. 6b illustrates a view of a channel in which it is sensed, by an electromagnetic induction panel of the electronic device 600 illustrated in FIG. 6a, that a magnitude of a signal is not greater than a critical value, according to an embodiment of the present disclosure.

In this embodiment, it is assumed that the predefined channel combination allowing a processor to turn off a display 630 includes a combination of channels F, G, and H 621a being a first channel and channels I and J 621b being a second channel.

As illustrated in FIG. 6a, if a front cover 612 covers the front housing of an electronic device 600,

magnets

612a and 612b included in the front cover 612 may apply a magnetic field to a housing. As such, the magnitude of a signal flowing into the first channel and the second channel corresponding to the location of a magnet may decrease.

According to an embodiment of the present disclosure, as illustrated in FIG. 6b, it may be sensed that the magnitude of a signal of each of the channels F, G, and H 621a in the first channel group is not greater than the first critical value, by using the

magnets

612a and 612b of the front cover 612; it may be sensed that the magnitude of a signal of each of channels I and J 621b in the second channel group is not greater than the second critical value, by using the

magnets

612a and 612b of the front cover 612. That is, points at which channels F, G, and H are intersected with channels I and J may correspond to the locations of the

magnets

612a and 612b of the front cover 612.

Since a combination of the channels F, G, and H 621a, in which it is sensed that the magnitude of the signal is not greater than the first critical value, and the channels I and J 621b, in which it is sensed that the magnitude of the signal is not greater than the second critical value, is included in the above-described predefined channel combination, the processor may turn off the display.

The operation of the processor in a state where a part of a

cover

710, 810, or 1010 mounts the

electronic device

700, 800, or 1000 while being attached to the rear surface of an

electronic device

700, 800, or 1000 will be exemplified with reference to FIGS. 7a and 10c.

In this embodiment, it is assumed that a predefined channel combination allowing a processor to display a screen displayed in a display, in a landscape mode includes a combination of channels G and H 721a being a first channel and channel K 721b being a second channel and a combination of channels G and H 821a being a first channel and channel L 821b being a second channel.

As illustrated in FIGS. 7a and 8a, if a part of the

cover

710 or 810 is attached to the rear surface of the

electronic device

700 or 800,

magnets

712b or 812b included in a part of the

cover

710 or 810 may apply a magnetic field to a housing. As such, the magnitude of a signal flowing into the first channel and the second channel corresponding to the location of the

magnets

712b or 812b may decrease.

In an embodiment of FIG. 7a, as illustrated in FIG. 7b, it may be sensed that the magnitude of a signal of each of the channels G and H 721a in the first channel group, by using the magnets 712b of the front cover 710 is not greater than the first critical value; it may be sensed that the magnitude of a signal of the channel K 721b in the second channel group, by using the magnets 712b of the front cover 710 is not greater than the second critical value.

That is, points at which channels G and H are intersected with channel K may correspond to the locations of the magnets 712a of the front cover 710.

In an embodiment of FIG. 8a, as illustrated in FIG. 8b, it may be sensed that the magnitude of a signal of each of the channels G and H 821a in the first channel group is not greater than the first critical value, by using the magnets 812b of the front cover 810; it may be sensed that the magnitude of a signal of the channel L 821b in the second channel group is not greater than the second critical value, by using the magnets 812b of the front cover 810.

That is, points at which channels G and H are intersected with channel L may correspond to the locations of the magnets 812b of the front cover 810.

Since a combination of the channels G and H 721a, in which it is sensed that the magnitude of a signal is not greater than the first critical value, and the channel K 721b, in which it is sensed that the magnitude of a signal is not greater than the second critical value, and a combination of the channels G and H 821a, in which it is sensed that the magnitude of a signal is not greater than the first critical value, and the channel L 821b, in which it is sensed that the magnitude of a signal is not greater than the second critical value, are included in the above-described predefined channel combination, the processor may display a screen displayed in a display in a landscape mode.

For example, when the display, like a display 930 of FIG. 9a, of the

electronic device

700 or 800 of FIG. 7a or 8a displays a screen in a portrait mode, if a channel combination corresponds to one of predefined channel combinations, the processor may display the screen in the landscape mode as illustrated the display 930 of FIG. 9b.

Referring to FIGS. 7a and 8a, an angle at which the

cover

710 or 810 in each embodiment mounts the

electronic device

700 or 800 may be different. For the purpose of displaying another user interface depending on a mounting angle, if the first channels in which it is sensed that the magnitude of a signal is not greater than the first critical value are the same as each other, and the second channels in which it is sensed that the magnitude of a signal is not greater than the second critical value are different from each other, the processor may display a different user interface in a display.

If FIG. 7b is compared with FIG. 8b, the first channel constituting a channel combination of FIG. 7b and a channel combination of FIG. 8b may be channels G and

H

721a or 821a. However, the second channel constituting the channel combination of FIG. 7b may be the channel K 721b, and the second channel constituting the channel combination of FIG. 8b may be the channel L 821b.

In this embodiment, since the first channels constituting a channel combination of FIG. 7a and a channel combination of FIG. 8a are the same as each other, and the second channels are different from each other, the processor may display a different user interface in the display.

For example, in the case where a channel combination in which it is sensed that the magnitude of the signal is not greater than a critical value is the same as the channel combination of FIG. 7b, the processor may display a user interface as illustrated in the display of FIG. 9b. In the case where a channel combination in which it is sensed that the magnitude of the signal is not greater than the critical value is the same as the channel combination of FIG. 8b, the processor may display the SIP illustrated in FIG. 9c, unlike FIG. 9b. The SIP displayed in FIG. 9c may be a virtual keyboard. However, a user interface that the processor differently displays is not limited to this exemplification.

Meanwhile, referring to FIGS. 10a to 10c, the tilt angle range of a pen input device may be different depending on an angle at which the electronic device 1000 is mounted. Even though the end of a pen input device 1050 is located at the same point, the location of the pen input device 1050 that an electromagnetic induction panel detects may be changed depending on the tilt angle.

To correct the location of the pen input device 1050, which is sensed depending on a mounting angle, the processor may apply different correction values to the location of the pen input device 1050, which is sensed by the electromagnetic induction panel, based on a channel combination of at least one first channel and at least one second channel.

For example, in the case where the channel combination in which it is sensed that the magnitude of the signal is not greater than a critical value is the same as the channel combination of FIG. 7b, the processor may apply a predefined first correction value to the sensed location of the pen input device 1050. In the case where the channel combination in which it is sensed that the magnitude of the signal is not greater than a critical value is the same as the channel combination of FIG. 8b, the processor may apply a predefined second correction value to the sensed location of the pen input device 1050.

The operation of the processor that distinguishes a state where the front cover 612 covers a front housing from a state where a front cover 1112 is folded back to cover a rear housing will be exemplified with reference to FIGS. 6a, 6b, 11a, and 11b.

FIG. 6a illustrates a view of how the front cover 612 covers a front housing of the electronic device 600, according to an embodiment of the present disclosure. FIG. 6b illustrates a view of a channel in which it is sensed, by an electromagnetic induction panel 620 of an electronic device illustrated in FIG. 6a, that a magnitude of a signal is not greater than a critical value, according to an embodiment of the present disclosure.

FIG. 11a illustrates a view of how the front cover 1112 is folded to a rear surface of an electronic device, according to an embodiment of the present disclosure. FIG. 11b illustrates a view of a channel in which it is sensed, by an electromagnetic induction panel including a shield plate in at least a portion of an electronic device illustrated in FIG. 11a, that a magnitude of a signal is not greater than a critical value, according to an embodiment of the present disclosure.

In this embodiment, it is assumed that the predefined channel combination allowing a processor to turn off a display includes a combination of channels F, G, and H 621a being the first channel and channels I and J 621b being the second channel.

As described above, if the front cover 612 covers the front housing of an electronic device as illustrated in FIG. 6a, the processor may turn off a display.

As illustrated in 11a, if the front cover 1112 is folded back to cover a rear housing 1111 of an electronic device 1100, a

magnet

1112a and 1112b included in the front cover 1112 may apply a magnetic field to the rear housing 1111. As such, the magnitude of a signal flowing into a first channel and a second channel corresponding to locations of the

magnet

1112a or 1112b may decrease.

As illustrated in FIG. 6b, it may be sensed that the magnitude of a signal of each of the channels F, G, and H 621a in the first channel group is not greater than the first critical value, by using the

magnets

612a and 612b of the front cover 612; it may be sensed that the magnitude of a signal of each of the channels I and J 621b in the second channel group is not greater than the second critical value, by using the

magnets

612a and 612b of the front cover 612.

In both the case where the front cover 1112 is folded back as illustrated in FIG. 11a and the case where the front cover 612 covers a front housing as illustrated in FIG. 6a, locations at which the

magnets

1112a, 1112b, 612a, and 612b of the

front cover

1112 or 612 applies a magnetic field to a housing may be almost the same. In both two cases, it may be sensed that the magnitude of a signal of each of channels F, G, and H in the first channel group is not greater than the first critical value, and it may be sensed that the magnitude of a signal of each of channels I and J in the second channel group is not greater than the second critical value. Accordingly, the processor may turn off the display.

As such, if the operation of a processor in the case where the front cover 612 covers the front housing is the same as the operation of the processor in the case where the front cover 1112 covers the rear housing 1111, a user may be inconvenient to use the electronic device. To determine whether the location of the

magnet

612a, 612b, 1112a or 1112b applying the magnetic field is the front surface of the housing or the rear surface of the housing, the processor may be configured to perform the following operation.

In an embodiment, an electromagnetic induction panel may include a shield plate capable of shielding the magnetic field, on at least part of one surface. In the case where the shield plate is included in at least part of the rear surface of the electromagnetic induction panel, the intensity of the magnetic field applied to the electromagnetic induction panel through the rear housing may be smaller than the intensity of the magnetic field applied to the electromagnetic induction panel through the front housing. The processor may be configured to perform different operations based on at least one of the magnitude of a signal flowing into a first channel group and a second channel group of the electromagnetic induction panel or the combination of channels.

That is, if the magnitude of a signal flowing into at least one first channel in the first channel group and the magnitude of a signal flowing into at least one second channel in the second channel group satisfy a first range, the processor may be configured to perform a first operation. Moreover, if the magnitude of a signal flowing into the at least first channel in the first channel group and the magnitude of a signal flowing into the at least second channel in the first channel group satisfy a second range, the processor may be configured to perform a second operation distinguished from the first operation.

For example, as illustrated in FIG. 6a, if the magnitude of a signal flowing into the at least one first channel and the magnitude of a signal flowing into the at least one second channel satisfy the first range, the processor may turn off the display. Furthermore, as illustrated in FIG. 11a, if the magnitude of a signal flowing into the at least one first channel and the magnitude of a signal flowing into the at least one second channel satisfy the second range, the processor may perform an operation (e.g., maximally setting the brightness of the display) distinguished from an operation of turning off the display.

In another embodiment, it is assumed that the predefined channel combination allowing the processor to perform the first operation includes a combination of channels F, G, and H 621a being the first channel and channels I and J 621b being the second channel. It is assumed that the predefined channel combination allowing the processor to perform the second operation distinguished from the first operation includes a combination of channels G and H 1121a being the first channel and channel J 1121b being the second channel.

Since the shield plate is included in a part of the rear surface of an electromagnetic induction panel 1120, the magnetic field by the first magnet 1112a is shielded. Accordingly, the magnetic field by the first magnet 1112a may not be applied to the electromagnetic induction panel, and the magnetic field by the second magnet 1112b may be applied to the electromagnetic induction panel. As such, the magnitude of a signal flowing into the first channel 1121a and the second channel 1121b of FIG. 11b corresponding to locations of the

magnet

1112a or 1112b may decrease.

As illustrated in FIG. 11b, it may be sensed that the magnitude of a signal flowing into the channels G and H 1121a in the first channel group is not greater than the first critical value, by using the magnets 1112a of the front cover 1112; it may be sensed that the magnitude of a signal flowing into the channel J 1121b in the second channel group is not greater than the second critical value, by using the magnets 1112a of the front cover 1112. That is, points at which channels G and H are intersected with channel L may correspond to the locations of magnets of the front cover 1112.

Since the combination of channels G and H, in which it is sensed that the magnitude of the signal is not greater than the first critical value, and channel J, in which it is sensed that the magnitude of the signal is not greater than the second critical value is included in a channel combination allowing the processor to perform the second operation, the processor may perform the second operation distinguished from the first operation.

As described above, if the magnitude of a signal flowing into at least one first channel and the magnitude of a signal flowing into at least one second channel satisfy a first range, the processor may be configured to perform a first operation. Moreover, if the magnitude of a signal flowing into the first channel and the magnitude of a signal flowing into the second channel satisfy a second range, the processor may be configured to perform a second operation distinguished from the first operation. An embodiment thereof will be described with reference to FIGS. 12a and 12b.

FIG. 12a illustrates a view of a cover, according to an embodiment of the present disclosure.

FIG. 12b illustrates a view of a channel in which it is sensed, by an electromagnetic induction panel of an electronic device in which a cover of FIG. 4a is mounted, that a magnitude of a signal is not greater than a critical value, according to an embodiment of the present disclosure.

In this embodiment, in the case where the first channel in which it is sensed that the magnitude of a signal is not greater than the first critical value, is one of channels A, B, and C 1221a, and the second channel in which it is sensed that the magnitude of a signal is not greater than the second critical value, is one of channels D and E 1221b, the processor may sense that a cover 1210 of FIG. 12a is attached to the electronic device. A first range in which the processor performs the first operation may be defined as a range in which the magnitude of a signal flowing into the channels A, B, and C 1221a is not greater than a third critical value less than the first critical value and the magnitude of a signal flowing into the channel D 1221b is not greater than a fourth critical value less than the second critical value. A second range in which the processor performs the second operation may be defined as a range in which the magnitude of a signal flowing into the channels A, B, and C 1221a is not greater than the third critical value less than the first critical value and the magnitude of a signal flowing into the channel E 1221b is not greater than the fourth critical value less than the second critical value.

In an embodiment, as illustrated in FIG. 7a or 8a, when the cover of FIG. 12a mounts the electronic device, a second magnet 1212b of a front cover 1212 may be located at a point corresponding to a

magnet

1211a or 1211b of a back cover 1211. For example, as illustrated in FIG. 7a, in the case where the electronic device is mounted, the second magnet 1212b of the front cover 1212 in FIG. 12a may be magnetically coupled to the second magnet 1211b of the back cover 1211. For another example, in the case where the electronic device is mounted as illustrated in FIG. 8a, the second magnet 1212b of the front cover 1212 in FIG. 12a may be magnetically coupled to the first magnet 1211a of the back cover 1211.

In both the case where the second magnet 1212b is magnetically coupled to the second magnet 1211b of the back cover 1211 and the case where the second magnet 1212b is magnetically coupled to the first magnet 1211a of the back cover 1211, the

magnets

1211a, 1211b, and 1212b may apply a magnetic field to the same location of the electromagnetic induction panel. That is, since the second magnet 1212b at the same location as the location of the

magnet

1211a or 1211b of the back cover 1211 applies the magnetic field to the rear housing, the first channel, in which it is sensed that the magnitude of a signal is not greater than a first critical value may be the channels A, B, and C 1221a, and the second channel, in which it is sensed that the magnitude of the signal is not greater than a second critical value may be the channels D and E 1221b.

However, since a magnetic field by the second magnet 1212b is further applied to the electromagnetic induction panel, the intensity of the magnetic field applied to the electromagnetic induction panel may be greater than the intensity of the magnetic field by the

magnet

1211a or 1211b of the back cover 1211.

Accordingly, in the case where the second magnet 1212b is magnetically coupled to the second magnet 1211b of the back cover 1211, it may be sensed that the magnitude of a signal flowing into the channels A, B, and C 1221a in the first channel group is not greater than the third critical value less than the first critical value, and it may be sensed that the magnitude of a signal flowing into in channel D 1221b in the second channel group is not greater than the fourth critical value less than the second critical value. Since the magnitude of a signal flowing into a first channel and the magnitude of a signal of at least one second channel satisfy a first range, the processor may perform a first operation.

In the case where the second magnet 1212b is magnetically coupled to the first magnet 1211a of the back cover 1211, it may be sensed that the magnitude of a signal flowing into the channels A, B, and C 1221a in the first channel group is not greater than the third critical value less than the first critical value, and it may be sensed that the magnitude of a signal flowing into the channel E 1221b in the second channel group is not greater than the fourth critical value less than the second critical value. Since the magnitude of a signal flowing into the first channel and the magnitude of a signal flowing into at least one second channel satisfy a second range, the processor may perform a second operation.

As such, even though combinations of channels in which it is sensed that the magnitude of a signal is not greater than a critical value are the same as each other, the processor may perform an operation that is distinguished based on the magnitude of a signal flowing into each of the channels.

FIG. 13a illustrates a view of how a cover is coupled to an electronic device, according to another embodiment of the present disclosure. FIG. 13b illustrates a view of how a cover mounts an electronic device, according to FIG. 13a.

A cover 1310 illustrated in FIG. 13a may include at least one

magnet

1312a or 1312b and, unlike the cover 110 illustrated in FIG. 1, may be attached to a part of a rear housing 1311 of an electronic device 1300. That is, the cover 1310 of FIG. 13a may be a shape corresponding to the front cover 112 of FIG. 1.

As illustrated in FIG. 13b, a part of the cover 1310 illustrated in FIG. 13a may be attached to the rear housing 1311 to mount the electronic device 1300. In addition, although not illustrated, as illustrated in FIG. 5a, the cover 1310 may cover the front housing of the electronic device 1300.

Furthermore, even in the case where the cover 1310 of FIG. 13a is attached to the electronic device 1300, as described above, the processor may change a screen displayed in a display, based on the magnitude of a signal flowing into a first channel group and a second channel group.

FIG. 14 illustrates an electronic device in a network environment system, according to various embodiments.

Referring to FIG. 14, according to various embodiments, an electronic device 1401, a first electronic device 1402, a second electronic device 1404, or a server 1406 may be connected each other over a network 1462 or a short range communication 1464. The electronic device 1401 may include a bus 1410, a processor 1420, a memory 1430, an input/output interface 1450, a display 1460, and a communication interface 1470. According to an embodiment, the electronic device 1401 may not include at least one of the above-described elements or may further include other element(s).

For example, the bus 1410 may interconnect the above-described elements 1410 to 1470 and may include a circuit for conveying communications (e.g., a control message and/or data) among the above-described elements.

The processor 1420 may include one or more of a central processing unit (CPU), an application processor (AP), or a communication processor (CP). For example, the processor 1420 may perform an arithmetic operation or data processing associated with control and/or communication of at least other elements of the electronic device 1401.

The memory 1430 may include a volatile and/or nonvolatile memory. For example, the memory 1430 may store instructions or data associated with at least one other element(s) of the electronic device 1401. According to an embodiment, the memory 1430 may store software and/or a program 1440. The program 1440 may include, for example, a kernel 1441, a middleware 1443, an application programming interface (API) 1445, and/or an application program (or "an application") 1447. At least a part of the kernel 1441, the middleware 1443, or the API 1445 may be referred to as an "operating system (OS)".

For example, the kernel 1441 may control or manage system resources (e.g., the bus 1410, the processor 1420, the memory 1430, and the like) that are used to execute operations or functions of other programs (e.g., the middleware 1443, the API 1445, and the application program 1447). Furthermore, the kernel 1441 may provide an interface that allows the middleware 1443, the API 1445, or the application program 1447 to access discrete elements of the electronic device 1401 so as to control or manage system resources.

The middleware 1443 may perform, for example, a mediation role such that the API 1445 or the application program 1447 communicates with the kernel 1441 to exchange data.

Furthermore, the middleware 1443 may process task requests received from the application program 1447 according to a priority. For example, the middleware 1443 may assign the priority, which makes it possible to use a system resource (e.g., the bus 1410, the processor 1420, the memory 1430, or the like) of the electronic device 1401, to at least one of the application program 1447. For example, the middleware 1443 may process the one or more task requests according to the priority assigned to the at least one, which makes it possible to perform scheduling or load balancing on the one or more task requests.

The API 1445 may be, for example, an interface through which the application program 1447 controls a function provided by the kernel 1441 or the middleware 1443, and may include, for example, at least one interface or function (e.g., an instruction) for a file control, a window control, image processing, a character control, or the like.

The input/output interface 1450 may play a role, for example, of an interface which transmits an instruction or data input from a user or another external device, to other element(s) of the electronic device 1401. Furthermore, the input/output interface 1450 may output an instruction or data, received from other element(s) of the electronic device 1401, to a user or another external device.

The display 1460 may include, for example, a liquid crystal display (LCD), a light-emitting diode (LED) display, an organic LED (OLED) display, a microelectromechanical systems (MEMS) display, or an electronic paper display. The display 1460 may display, for example, various contents (e.g., a text, an image, a video, an icon, a symbol, and the like) to a user. The display 1460 may include a touch screen and may receive, for example, a touch, gesture, proximity, or hovering input using an electronic pen or a part of a user's body.

For example, the communication interface 1470 may establish communication between the electronic device 1401 and an external device (e.g., the first electronic device 1402, the second electronic device 1404, or the server 1406). For example, the communication interface 1470 may be connected to the network 1462 over wireless communication or wired communication to communicate with the external device (e.g., the second electronic device 1404 or the server 1406).

The wireless communication may use at least one of, for example, long-term evolution (LTE), LTE Advanced (LTE-A), Code Division Multiple Access (CDMA), Wideband CDMA (WCDMA), Universal Mobile Telecommunications System (UMTS), Wireless Broadband (WiBro), Global System for Mobile Communications (GSM), or the like, as cellular communication protocol. Furthermore, the wireless communication may include, for example, the short range communication 1464. The short range communication 1464 may include at least one of wireless fidelity (Wi-Fi), Bluetooth, near field communication (NFC), magnetic stripe transmission (MST), a global navigation satellite system (GNSS), or the like.

The MST may generate a pulse in response to transmission data using an electromagnetic signal, and the pulse may generate a magnetic field signal. The electronic device 1401 may transfer the magnetic field signal to point of sale (POS), and the POS may detect the magnetic field signal using a MST reader. The POS may recover the data by converting the detected magnetic field signal to an electrical signal.

The GNSS may include at least one of, for example, a global positioning system (GPS), a global navigation satellite system (Glonass), a Beidou navigation satellite system (hereinafter referred to as "Beidou"), or an European global satellite-based navigation system (hereinafter referred to as "Galileo") based on an available region, a bandwidth, or the like. Hereinafter, in this disclosure, "GPS" and "GNSS" may be interchangeably used. The wired communication may include at least one of, for example, a universal serial bus (USB), a high definition multimedia interface (HDMI), a recommended standard-232 (RS-232), a plain old telephone service (POTS), or the like. The network 1462 may include at least one of telecommunications networks, for example, a computer network (e.g., LAN or WAN), an Internet, or a telephone network.

Each of the first and second

electronic devices

1402 and 1404 may be a device of which the type is different from or the same as that of the electronic device 1401. According to an embodiment, the server 1406 may include a group of one or more servers. According to various embodiments, all or a portion of operations that the electronic device 1401 will perform may be executed by another or plural electronic devices (e.g., the first electronic device 1402, the second electronic device 1404 or the server 1406). According to an embodiment, in the case where the electronic device 1401 executes any function or service automatically or in response to a request, the electronic device 1401 may not perform the function or the service internally, but, alternatively additionally, it may request at least a portion of a function associated with the electronic device 1401 from another device (e.g., the

electronic device

1402 or 1404 or the server 1406). The other electronic device may execute the requested function or additional function and may transmit the execution result to the electronic device 1401. The electronic device 1401 may provide the requested function or service using the received result or may additionally process the received result to provide the requested function or service. To this end, for example, cloud computing, distributed computing, or client-server computing may be used.

FIG. 15 illustrates a block diagram of an electronic device, according to various embodiments.

Referring to FIG. 15, an electronic device 1501 may include, for example, all or a part of the electronic device 1401 illustrated in FIG. 14. The electronic device 1501 may include one or more processors (e.g., an application processor (AP)) 1510, a communication module 1520, a subscriber identification module 1529, a memory 1530, a sensor module 1540, an input device 1550, a display 1560, an interface 1570, an audio module 1580, a camera module 1591, a power management module 1595, a battery 1596, an indicator 1597, and a motor 1598.

The processor 1510 may drive, for example, an operating system (OS) or an application to control a plurality of hardware or software elements connected to the processor 1510 and may process and compute a variety of data. For example, the processor 1510 may be implemented with a System on Chip (SoC). According to an embodiment, the processor 1510 may further include a graphic processing unit (GPU) and/or an image signal processor. The processor 1510 may include at least a part (e.g., a cellular module 1521) of elements illustrated in FIG. 15. The processor 1510 may load an instruction or data, which is received from at least one of other elements (e.g., a nonvolatile memory), into a volatile memory and process the loaded instruction or data. The processor 1510 may store a variety of data in the nonvolatile memory.

The communication module 1520 may be configured the same as or similar to the communication interface 1470 of FIG. 14. The communication module 1520 may include the cellular module 1521, a Wi-Fi module 1522, a Bluetooth (BT) module 1523, a GNSS module 1524 (e.g., a GPS module, a Glonass module, a Beidou module, or a Galileo module), a near field communication (NFC) module 1525, a MST module 1526 and a radio frequency (RF) module 1527.
