The memory <NUM> may store data supporting various functions of the electronic device <NUM>. The memory <NUM> may store application programs (or applications) run in the electronic device <NUM>, data for operation of the electronic device <NUM>, and instructions. At least a portion of the application programs may be downloaded from an external server through wireless communication. Also, at least a portion of the application programs may exist in the electronic device <NUM> for a basic function (for example, call forwarding and outgoing function and message receiving and outgoing function) of the electronic device <NUM> from the time of manufacture. The application program may be stored in the memory <NUM>, installed in the electronic device <NUM>, and run by the controller <NUM> to perform an operation (or function) of the mobile terminal.

The controller <NUM> may generally control an overall operation of the electronic device <NUM> in addition to operations related to the application programs. The controller <NUM> may process a signal, data, information, and the like input or output through the aforementioned components or run the application program stored in the memory <NUM>, thereby providing information to a user or performing appropriate information or function.

Also, to run the application program stored in the memory <NUM>, the controller <NUM> may control at least a portion of the components shown in <FIG>. Furthermore, to run the application program, the controller <NUM> may operate a combination of two or more components among the components included in the electronic device <NUM>.

At least a portion of the aforementioned components may operate in cooperation with each other to implement an operation, a control, or a control method of the mobile terminal according to various embodiments as described below. Also, the operation, control, or control method of the mobile terminal may be implemented on the mobile terminal through an execution of at least one application program stored in the memory <NUM>.

In the present disclosure, the electronic device <NUM> may refer to a mobile terminal obtained by applying a flexible display to the above-described mobile terminal. The flexible display may refer to a flexible display to be bent such that a winding area is changed.

The flexible display may refer to a lightweight and durable display manufactured on a thin and flexible substrate so as to be curved, bendable, folded, twisted, or rolled like a paper while having a characteristic of a typical flat panel display.

The flexible display may implement a flexible touch screen in combination with a touch sensor. In response to a touch being input through the flexible touch screen, the controller <NUM> may perform a control corresponding to the touch input.

The touch sensor may sense a touch (or touch input) applied to the touch screen based on at least one of various touch types including a resistive type, a capacitive type, an infrared type, an ultrasonic type, and a magnetic field type.

As an example, the touch sensor may be configured to convert a change such as a pressure applied to a predetermined portion of the touch screen or a capacitance generated at the predetermined portion into an electrical input signal. The touch sensor may be configured to detect a position at which a touch object applying a touch on the touch screen is touched on the touch sensor, an area, a touch pressure, a touch capacitance, and the like.

The electronic device <NUM> may include a deformation detection part that detects a deformation of the flexible display. The deformation detection part may be included in the sensing part.

Information related to the deformation may include, for example, a direction in which the flexible display is deformed, a degree of deformation, a deformed position, a deformation time, and an acceleration at which the deformed flexible display is restored. In addition, the information related to the deformation may be various information to be detected in response to the flexible display being bent.

Also, based on the information related to the deformation of the flexible display detected by the deformation detection part, the controller <NUM> may change information displayed on the flexible display or generate a control signal for controlling functions of the electronic device <NUM>.

A state change of the flexible display, for example, an expansion or reduction of a front surface area may occur due to an external force but not be limited thereto. For example, the front surface area of the flexible display may be expanded or reduced by the user or based on a command of an application. A driver may be included to change the state of the flexible display without applying the external force.

When the flexible display covers from the front surface to a rear surface, a space implemented in a typical rear case to mount an antenna may be restricted. Thus, the antenna may be embodied on the flexible display. An antenna on display (AOD) may be in a form of a transparent film in which an electrode layer including a pattern and a dielectric layer are laminated. The AOD may be implemented to be thinner than a laser direct structuring (LDS) antenna implemented through copper nickel plating, have a low thickness dependency, and be invisible on appearance.

The display <NUM> may be implemented as the flexible display. The flexible display <NUM> may refer to a plurality of panel sets that directly perform an output function, including the flexible display. For example, the flexible display <NUM> may include the flexible display and the touch screen. The above-described properties of the deformable flexible display may be equally applied to the flexible display <NUM>. The display <NUM> mentioned below is assumed to be the flexible display <NUM> unless otherwise state.

<FIG> and <FIG> are conceptual diagrams illustrating the states before and after a display <NUM> of an electronic device <NUM> related to an embodiment of the present disclosure is extended.

Specifically, <FIG> illustrates the case where an edge on which a display <NUM> is rolled up and out in relation to extension is a first direction edge <NUM>, and <FIG> illustrates the case where an edge on which the display <NUM> is rolled up and out in relation to extension is a second direction edge <NUM> that opposes the first direction edge <NUM>.

Specifically, (a) in <FIG> illustrates an electronic device <NUM> with the display <NUM> which is extended, and (b) in <FIG> illustrates the electronic device <NUM> with the display <NUM> which is not extended.

Referring to <FIG>, the display <NUM> may have one side fixed at a front surface with reference to the electronic device <NUM> and may be rolled up on a first direction edge <NUM> to be provided on a back surface (or a rear surface). A front region 151F of the display <NUM> may be extended. When the front region 151F of the display <NUM> is extended, a rear region 151R of the display <NUM> may be reduced. On the contrary, when the front region 151F of the display <NUM> is reduced, the rear region 151R of the display <NUM> may be extended.

A direction in which the front region 151F of the display <NUM> is extended may be defined as a first direction, and a direction in which the front region 151F of the display <NUM> is reduced may be defined as a second direction. In this case, if the front region 151F of the display <NUM> increases in area, the first direction edge <NUM> of the display <NUM> may move in the first direction, and, if the front region 151F of the display <NUM> decreases in area, the first direction edge <NUM> of the display <NUM> may move in the second direction.

In order to guide and support the display <NUM> to be extended or retracted, a frame supporting the display <NUM> may be extended or retracted as well. The frame may include a first frame 151A and a second frame 151B, which slidably moves in the first direction relative to the first frame 151A.

A part of the front region 151F to be maintained regardless of extension and retraction of the display <NUM> may be defined as a fixed part 151U. A part of the front region 151F to be selectively exposed according to extension and retraction of the display <NUM> may be defined as a variable part 151X. In a state that the front region 151F of the display <NUM> is extended, the fixed part 151U of the display <NUM> may be positioned at the first frame 151A and the variable part 151X of the display <NUM> may be positioned at the second frame 151B.

When the second frame 151B slidably moves in the first direction to be extended from the first frame 151A, the front region 151F of the display <NUM> may be extended, causing the fixed part 151U and the variable part 151X to be exposed at the front surface. When the second frame 151B slidably moves in a direction opposite to the first direction to be retracted toward the first frame 151A, the front region 151F of the display <NUM> may be reduced as well, causing only the fixed part 151U to remain exposed at the front surface.

The rear region of the display <NUM> may be exposed at a rear surface of the second frame 151B. The rear region of the display <NUM> may be covered by a light-transmitting rear window and therefore visible from the outside.

Meanwhile, the front region 151F of the display <NUM> may be exposed at a front surface without an additional window. In some cases, however, a deco frame may cover a boundary region between the front region 151F and the first frame 151A, thereby preventing an external material and covering a bezel region of the electronic device to help visibility of a screen for a user.

An electronic part may be formed in an inner surface formed by external structures such as the first frame 151A and the second frame 151B. An electronic component for driving the electronic device <NUM>, such as a battery <NUM>, may be mounted at a main Printed Circuit Board (PCB) and thus provided in the electronic part. Alternatively, an electronic component such as an internal antenna module may be mounted directly at the electronic part rather than mounted at the main PCB.

In an embodiment, the electronic device <NUM> may include a driving part for controlling a size of the display <NUM>. The driving part may be implemented, for example, using a motor. The electronic device100 may control a size of the display <NUM> by controlling a moving direction of the first direction edge <NUM> of the display <NUM> using a motor.

Specifically, (a) of <FIG> illustrates an electronic device <NUM> with a display <NUM> which is extended, and (b) of <FIG> illustrates the electronic device <NUM> with the display <NUM> which is not extended.

Referring to <FIG>, the display <NUM> may have one side fixed at a front region with reference to the electronic device <NUM> and may be rolled up on a second direction edge <NUM> to be provided over a back surface (or a rear surface). A front region 151F of the display <NUM> may be extended. When the front region 151F of the display <NUM> is extended, a rear region 151R of the display <NUM> may be reduced. On the contrary, when the front region 151F of the display <NUM> is reduced, the rear region 151R of the display <NUM> may be extended.

A direction in which the front region 151F of the display <NUM> is extended may be defined as a first direction, and a direction in which the front region 151F of the display <NUM> is reduced may be defined as a second direction. In this case, even when the front region 151F of the display <NUM> increases or decreases in area, the second direction edge <NUM> of the display <NUM> may remain at the same position. A redundant description of <FIG> with <FIG> will be omitted.

In <FIG> and <FIG>, the display is described as being extended in the first direction, but is not limited thereto. For example, the display may be extended in the second direction. In the following description, the display may be extended in various directions (e.g., the first direction or the second direction).

In the example embodiment, the event-related information <NUM> is displayed for a predetermined time. In some cases, after the predetermined time elapses, displaying of the event-related information <NUM> may be suspended and a screen of the reference numeral 4a may be displayed.

In the example embodiment, the electronic device may receive a specific input corresponding to the event related to the notification. The specific input may include a user input to a specific position (e.g., at least a portion of a second surface) of the display.

In response to the specific input being received, the electronic device may display notification-related content <NUM> as indicated by reference numeral 4c. The notification-related content <NUM> may include content corresponding to the notification and content associated with information to be indicated through the notification. As an example, the notification-related content <NUM> may include at least one of a text and an image related to the notification. As another example, when an application providing the notification is a messenger application, the notification-related content <NUM> may include a message.

The notification-related content <NUM> may be displayed in at least a portion of the first surface of the electronic device. For example, the notification-related content <NUM> is displayed at an upper end of the display placed horizontally.

<FIG> illustrates content displayed on a second surface of an electronic device according to an example embodiment of the present disclosure.

Reference numeral 5a represents an example of a second surface of an electronic device. A portion <NUM> of a display may be located at the second surface of the electronic device. The display may be wound on one surface of the electronic device to be located at a first surface and the second surface. The portion <NUM> of the display shown in <FIG> may be a display located at the second surface.

Specifically, the display may be located in at least a portion of the second surface. As illustrated, the display may be located to occupy an overall upper end portion of the second surface but is not limited thereto. The portion <NUM> of the display may be located to correspond to a specific area, for example, an area <NUM>.

Reference numeral 5b represents an example of displaying notification-related content <NUM> on a display of the second surface. In the example embodiment, the notification-related content <NUM> may be displayed on the display of the second surface based on an event related to a notification. As an example, the notification-related content <NUM> may be displayed in response to the notification being received. As another example, the notification-related content <NUM> may be displayed on the display of the second surface while the screen of the reference numeral 4b of <FIG> is on the display of the first surface.

The notification-related content <NUM> may be displayed in at least a portion of the display of the second surface. For example, the notification-related content <NUM> may be displayed in a portion of an upper end of the display placed horizontally.

In the example embodiment, when the display corresponds to the area <NUM> of the reference numeral 5a, the notification-related content <NUM> may be displayed in the area <NUM>.

<FIG> is a functional block diagram illustrating an electronic device according to an example embodiment of the present disclosure. As described below, an element of an electronic device <NUM> may be a unit that processes at least one function or operation and may be implemented through hardware, software, or a combination of hardware and software.

The electronic device <NUM> includes a first sensor <NUM>, a second sensor <NUM>, a display <NUM>, and a controller <NUM>. In some cases, the first sensor <NUM> or the second sensor <NUM> may be omitted.

The first sensor <NUM> may include a proximity sensor. Specifically, the first sensor <NUM> may include a proximity sensor that senses a living body or an object approaching within a predetermined radius. The first sensor <NUM> may be disposed in at least a portion of the electronic device <NUM>. For example, the first sensor <NUM> may be disposed in an upper portion of a first surface (e.g., a front surface) of the electronic device <NUM>.

The second sensor <NUM> may include a pose recognition sensor. Specifically, the second sensor <NUM> may include a pose recognition sensor (e.g., a gyro sensor) that detects a pose of the electronic device <NUM> including the second sensor <NUM>.

In the example embodiment, the second sensor <NUM> may detect whether a pose of the electronic device <NUM> is horizontal or vertical. However, embodiments are not limited thereto. The second sensor <NUM> may detect whether the electronic device <NUM> is upside down. Since it is obvious to those skilled in the art, related description will be omitted.

The display <NUM> may be provided such that a size by which the display <NUM> is exposed on a first surface of the electronic device <NUM> (e.g., a front surface of the electronic device <NUM>) can be changed. The display <NUM> may be implemented to be flexible.

The display <NUM> may display a variety of information associated with an operation of the electronic device <NUM>. For example, the display <NUM> may display content of an application provided based on an execution of the application or content representing the application.

In the example embodiment, a portion of the display <NUM> may be located at the first surface. Also, another portion may be wound at one surface of the electronic device <NUM> to be located at a second surface of the electronic device <NUM>. Here, the first surface may include the front surface of the electronic device <NUM> and the second surface may include a rear surface of the electronic device <NUM> facing the first surface.

Specifically, the display <NUM> may be bent at one end in contact with the first surface, so that at least a portion is located at the first surface and at least another portion is located at the second surface in contact with the one end. Since the related description has been made with reference to <FIG> or <FIG>, repeated description is omitted.

The controller <NUM> may display application-related content in a first area. The first area may include an area of at least a portion of the display located at the first surface of the electronic device <NUM>. That is, the controller <NUM> may display the content related to the application in the first area of the first surface.

The application-related content may include, for example, visual content to be viewed by a user such as multimedia but not limited thereto.

The controller <NUM> may identify a notification-related event. The notification-related event may include an event set to provide a notification. For example, the notification-related event may include a situation in which a message is received. The notification may include information indicating that the message is received.

The controller <NUM> may display event-related information in at least a portion of the first area in response to the notification-related event. For example, when the first area corresponds to the entire display located at the first surface, the controller <NUM> may display the event-related information in an area in an upper end portion of the first area.

The event-related information may include specific content. The event-related information may include, for example, a specific image or a specific light emitting pattern. Here, the specific light emitting pattern may include a pattern for a color or a brightness of at least a portion of the display. This is merely an example of the event-related information and the event-related information may be implemented as various content.

In the example embodiment, the event-related information may be designated for each event. For example, when an event is related to a message reception, the event-related information may be designated to first content. Also, when an event is related to a game invitation, the event-related information may be designated to second content.

In the example embodiment, the event-related information may be designated for each application. For example, when an alarm event is related to a first application, the event-related information may be designated to first content. Also, when an alarm event is related to a second application, the event-related information may be designated to second content.

Here, the first content and the second content may be implemented to have the same configuration and different colors. However, this is merely an example and the first content and the second content may also be implemented as content having different configurations.

In response to a first input to a second area, the controller <NUM> may display at least a portion of notification-related content in the first area. The second area may include an area of a displayed located at a second surface (e.g., a rear surface) of the electronic device <NUM>.

The notification-related content may include content corresponding to a target for notification. As an example, when a notification informs of a message reception, the notification-related content may include a received message. As another example, when a notification informs of a game invitation, the notification-related content may include at least one of a text and an image showing details of the game invitation.

The electronic device may store the notification-related content corresponding to the notification-related event. In some cases, a plurality of notification-related events may occur. In such cases, the electronic device may store notification-related content corresponding to each of the notification-related events.

The first input may be an input designated in advance. As an example, the first input may include a touch input to the second area. As another example, the first input may include a touch input to the first area. In some cases, the first input may include an input applied to a specific point or an input to at least one point. However, the aforementioned examples are not to be taken as being limited thereto.

In the example embodiment, the first input may include an input maintained for a predetermined time. For example, the first input may include an input of which a touch is maintained for a first period of time. In this example, the controller <NUM> may display at least a portion of the notification-related content in the first area for the first period of time, that is, a time in which the first input is maintained.

In the example embodiment, the controller <NUM> may identify a second input to a proximity sensor. In this case, the controller <NUM> may display at least a portion of the notification-related content in the first area in response to the second input. The second input may be included in the first input or may include an input maintained for a predetermined time as described above. In such a case, the controller <NUM> may display at least a portion of the notification-related content in the first area for a time in which the second input is maintained.

In the example embodiment, the controller <NUM> may activate an input detection for the second area based on an event. The controller <NUM> may identify an input applied to the second area in response to the input detection being activated. The controller <NUM> may set an input to be detected from the second area in response to the event being identified, and identify an input applied to the second area.

In the example embodiment, in a general situation irrelevant to the event, the controller <NUM> may deactivate the input detection for the second area. The deactivation of the input detection may include a situation in which an applied input is neglected or the input detection is not performed due to a power blockage. Once the input detection is deactivated, even if an input is applied to the second area, the controller <NUM> may neglect the input. Alternatively, the input to the second area may not be detected by the controller <NUM>.

In the example embodiment, the controller <NUM> may display at least a portion of the notification-related content in the second area. As an example, the controller <NUM> may display at least a portion of the notification-related content in the second area based on the notification-related event. As another example, when the notification-related event is identified, the controller <NUM> may display at least a portion of the notification-related content in the second area for a predetermined time.

The controller <NUM> may control at least one of a display brightness corresponding to the first area and a display brightness corresponding to the second area based on a pose of the electronic device <NUM>. As an example, when a pose of the electronic device <NUM> is a first pose, the controller <NUM> may adjust the display brightness corresponding to the first area to a first brightness and adjust the display brightness corresponding to the second area to a second brightness. In some cases, the notification-related content may be displayed in the second area.
