BACKGROUND
Various embodiments of the present disclosure relate to a case for an electronic device, an electronic device using the case, and a notification method thereof.
Recently, the dissemination and use of electronic devices (e.g., mobile communication terminals) has rapidly increased due to the remarkable development of information and communication technology and semiconductor technology. Accordingly, the electronic devices are necessities for modern people, and provide various functions desired by users. For example, the mobile communication terminal provides various functions, such as phone-calling, photographing images or movies, receiving broadcasts, connecting to the Internet, or recording.
In addition, the electronic device may receive a variety of information. For example, the electronic device may receive text messages, e-mails, call requests, advertisement messages, or the like. The electronic device may visually notify the user of the reception of a variety of information. For example, the electronic device may display icons or pop-up windows on the display in order to thereby notify the user of the receipt of the information.
Meanwhile the user may not check the received information in real time. Therefore, the electronic device may notify the user of the presence of the information that has not been checked by the user (hereinafter, “unidentified information”) through a separate light-emitting diodes (e.g., LEDs).
SUMMARY
In general, the light-emitting device is positioned on the front side of the electronic device, on which a display is provided. Since the light-emitting device is provided on the front side of the electronic device, if the front side of the electronic device is blocked (e.g., when the electronic device is placed upside down on the table), the user may not notice the light-emitting of the light-emitting device. That is, when the front side of the conventional electronic device is blocked, the user cannot recognize the visual notification of the electronic device, which notifies of the receipt of the information or the presence of the unidentified information.
In addition, in recent years, various cases for protecting the electronic devices have been introduced. In other words, in the case of the electronic devices that are fastened to the cases, when the front side of the electronic device is blocked by the flip cover of the case or when the electronic device is placed upside down, the user cannot recognize the visual notification of the electronic device.
Various embodiments of the present disclosure provide a case for an electronic device, an electronic device using the same, and a notification method thereof, which can notify the user of the occurrence of various events or the presence of the unidentified information through at least one of the lateral side or the back side of the electronic device even when the front side of the electronic device is blocked.
In accordance with an aspect of the present disclosure, a case for an electronic device having a lateral side, a back side, and a display to emit light may include: a body that is fastened to the electronic device; and a light guide unit that is formed in the body, and guides the light emitted from the display of the electronic device to at least one of the lateral side or the back side of the electronic device to be output to the outside.
In accordance with another aspect of the present disclosure, an electronic device may include: a display; a sensor unit that includes one or more sensors to check a status of the electronic device; a controller that, when an event is detected, determines whether or not a front-side notification of the electronic device is viable by using the sensor unit, and if a front-side notification is unviable, activates at least a portion of the display to emit light; and a light guide unit that guides the light emitted from the portion of the display that has been activated to at least one of the lateral side or the back side of the electronic device to be output to the outside.
In accordance with another aspect of the present disclosure, a notification method of an electronic device that a) has 1) a lateral side, 2) a back side, and 3) a display configured to emit light, and b) is fastened to a case that has a light guide unit may include: when an event is detected, determining whether or not a front-side notification of the electronic device is viable; and if a front-side notification is unviable, activating at least a portion of the display, wherein the light emitted from the portion of the display that has been activated is guided to at least one of the lateral side or the back side of the electronic device through the light guide unit to then be output to the outside.
Various embodiments of the present disclosure can visually notify the user of the occurrence of the event through at least one of the lateral side or the back side in the case where the user cannot recognize the visual notification on the occurrence of the event through the front side of the electronic device (e.g., when the front side of the electronic device is blocked). Accordingly, various embodiments of the present disclosure can visually notify the user of the occurrence of the event in a variety of situations.
In addition, since the electronic device, according to various embodiments of the present disclosure, does not adopt a separate notification unit for notifying of the occurrence of the event, the manufacturing cost of the electronic device can be reduced.

FIG. 6 is a view for explaining various notification methods of the electronic device, according to an embodiment of the present disclosure.
Referring to FIG. 6, a battery cover of the electronic device 600 or a case attached to the electronic device 600 may include a plurality of light guide units 613. The plurality of light guide units 613 may be arranged in a single file line (single-row multi-column). Meanwhile, although the light guide units 613 are illustrated as being exposed to the outside in FIG. 6 for convenience of explanation, the light guide units 613 are not actually exposed to the user.
The electronic device 600 may roughly recognize the display position of a pop-up window or an icon according to the occurrence of the event through the light guide units 613 arranged in a single file line (single-row multi-column). For example, when the pop-up window is displayed at the position corresponding to the first area 601 according to the occurrence of the event, the light guide units 613 of the first area 601 may output a light of a different color from the light guide units 613 of a second area 602, a third area 603, and a fourth area 604. According to this, the user may recognize that the pop-up window is displayed at the upper area of the display, which corresponds to the first area 601.
In addition, if the display position of the pop-up window or the icon is different depending on events, the user may roughly recognize the type of event. For example, when the IM message or the advertisement message is received, the pop-up window may be displayed in the second area 602, and when the text message or the e-mail is received, a text icon or an e-mail icon may be displayed in the first area 601. In this case, if the light from the light guide units 613 of the second area has a different color from the light of other areas, the user may recognize that the IM message or the advertisement message has been received.
According to some embodiments, the electronic device 600 may configure the light-emitting area to be different depending on the type of event. For example, the electronic device 600 may emit light in the first area 601 when the text message is received. To this end, the electronic device 600 may activate a portion of the display, which corresponds to the first area 601. Alternatively, the electronic device 600 may allow the portion of the display corresponding to the first area 601 to emit a light of a specific color (e.g., yellow), and may allow the remaining portion thereof to emit a black light.
Alternatively, the electronic device 600 may: allow the second area 602 to emit light when a call request is received; allow the third area 603 to emit light when the e-mail is received; and allow the fourth area 604 to emit light when the advertisement message is received.
According to some embodiments, the electronic device 600 may configure the light-emitting color to be different depending on the type of event. For example, the electronic device 600 may emit a yellow light in at least a part of the display when the text message is received, and may emit a blue light in at least a part of the display when the call request is received.
According to some embodiments, the electronic device 600 may configure the light-emitting area and the light-emitting color to be different depending on the type of event.
Meanwhile, although a plurality of light guide units are arranged in a single file line (single-row multi-column) in FIG. 6, the plurality of light guide units may be arranged in a single lateral line (multi-row single-column) or in a multi-line and column (multi-row multi-column).
Further, although FIG. 6 shows an example of the back-side notification, the electronic device, according to some embodiments, may have a plurality of light guide units provided on the lateral side thereof, and may notify the user of the occurrence of the event, the position, or the type of event by using the plurality of light guide units provided on the lateral side in a similar manner as FIG. 6.
FIG. 7A and FIG. 7B are views for explaining the back-side notification method of an electronic device, according to an embodiment of the present disclosure.
Referring to FIG. 7A and FIG. 7B, the electronic device 700, according to an embodiment of the present disclosure, may provide the back-side notification in the form of an icon. For example, as shown in FIG. 7A, the electronic device 700 may display a text message icon 721 on the back side upon the receipt of a text message. More specifically, when the text message is received, the electronic device 700 may activate a portion of the display corresponding to the first area 701. The light output from the portion of the activated display is transferred to the first area 701 to then be output to the outside in order to thereby display the text message icon 721.
Likewise, when a call request is received, the electronic device 700 may activate a portion of the display corresponding to the second area 702 in order to thereby display a handset icon 722.
Referring to FIG. 7B for more detailed description, when the event occurs while the display of a touch screen 730 is blocked by a front cover 710, the light of the display is transferred to a light diffusion plate 713b of a back cover 720 through an optical waveguide 713a, and may be diffused by the light diffusion plate 713b. The diffused light may be emitted to the outside in a specific form (icon) by a pattern layer 714 that is formed (printed or coated) on the light diffusion plate 713b. 
More specifically, the pattern layer 714 may include a non-penetration area 714a through which the light of the display cannot pass, and a penetration area 714b through which the light of the display can pass. The penetration area 714b is normally opaque without the light of the display.
Meanwhile, FIG. 7A shows the pattern layer 714 that displays the text message icon 721 and the handset icon 722. However, according to other embodiments of the present disclosure, the pattern layer may be formed to display three or more icons.
In addition, although it is not shown in the drawings, the back cover 720 may include a reflective plate that is formed in the bottom area 711 of the light diffusion plate 713b in order to reflect the light, which is emitted downwards, into the top of the light diffusion plate 713b. 
FIG. 8 is a block diagram showing the configuration of the electronic device, according to an embodiment of the present disclosure.
Referring to FIG. 8, the electronic device 800, according to an embodiment of the present disclosure, may include a controller 810, a memory 820, a touch screen 830, a sensor unit 840, a communication unit 850, an audio processing unit 860, and a light-emitting unit 870. The touch screen 830 may include a display 831 and a touch detecting unit 832.
The controller 810 may control the overall operation of the electronic device 800 and a signal flow between internal blocks of the electronic device 800, and may perform a data processing function. For example, the controller 810 may be implemented by a Central Processing Unit (CPU), an application processor, or the like. The controller 810 may be formed of a single-core processor or a multi-core processor. In addition, the controller 810 may be comprised of a plurality of processors.
The controller 810, according to various embodiments, may control the notification providing process. For example, the controller 810 may identify the status of the electronic device 800 through the sensor unit 840 when the event occurrence is detected, and may provide the front-side/back-side notification. More specifically, if the front-side notification of the electronic device is unviable, the controller 810 may activate at least a part of the display 831, and may transfer the light emitted from the part of the display to at least one of the lateral side or the back side of the electronic device in order to thereby provide the lateral-side/back-side notification. On the contrary, if the front-side notification is viable, the controller 810 may notify the user of the occurrence of the event through the display 831 and/or the light-emitting unit 870.
