Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in an inner region of the mobile terminal covered by the touch screen described above or near the touch screen.

Examples of the proximity sensor 141 include a transmissive photoelectric sensor, a direct reflective photoelectric sensor, a mirror reflective photoelectric sensor, a high frequency oscillating proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object by the change of the electric field according to the proximity of the conductive object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, an action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching an object on a screen is called a "contact touch." The position at which the object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, and a proximity touch movement state). have. Meanwhile, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern detected through the proximity sensor 141 as described above, and further, provides visual information corresponding to the processed data. It can be output on the touch screen. Further, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) according to whether the touch on the same point on the touch screen is a proximity touch or a touch touch. .

The touch sensor may be configured to detect a position, an area, a pressure at the touch, a capacitance at the touch, and the like, when the touch object applying the touch on the touch screen is touched on the touch sensor. Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

As such, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and then transmits the corresponding data to the controller 180. As a result, the controller 180 can know which area of the display unit 151 is touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different control or perform the same control according to the type of touch object that touches the touch screen (or a touch key provided in addition to the touch screen). Whether to perform different control or the same control according to the type of touch object may be determined according to the operation state of the mobile terminal 100 or an application program being executed.

The ultrasonic sensor may recognize location information of a sensing object using ultrasonic waves. On the other hand, the controller 180 can calculate the position of the wave generation source through the information detected from the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generation source may be calculated using a time difference from the time when the ultrasonic wave reaches the light as the reference signal.

On the other hand, the camera 121, which has been described as the configuration of the input unit 120, includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to detect a touch of a sensing object with respect to a 3D stereoscopic image. The photo sensor may be stacked on the display element, which is configured to scan the movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents mounted on the photo sensor by using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position information of the sensing object can be obtained.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven in the mobile terminal 100 or user interface (UI) and graphical user interface (GUI) information according to the execution screen information. .

The sound output unit 152 may include a receiver, a speaker, a buzzer, and the like.

The haptic module 153 generates various haptic effects that a user can feel. A representative example of the tactile effect generated by the haptic module 153 may be vibration. The intensity and pattern of vibration generated by the haptic module 153 may be controlled by the user's selection or the setting of the controller. For example, the haptic module 153 may synthesize different vibrations and output or sequentially output them.

In addition to vibration, the haptic module 153 may be used to stimulate pins that vertically move with respect to the contact skin surface, jetting force or suction force of air through the jetting or suction port, grazing to the skin surface, contact of electrodes, and electrostatic force Various tactile effects can be generated, such as effects by the endothermic and the reproduction of a sense of cold using the elements capable of endothermic heat generation.

The second touch screen 151b includes a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), and a flexible display. The display device may include at least one of a flexible display, a 3D display, and an e-ink display.

In the closed state, the first touch screen 151a is accommodated in at least one of the first and second bodies 101 and 102 and the state information of the mobile terminal 100 is displayed on the second touch screen 151b. Can be.

Referring to FIG. 3B, one end of the first touch screen 151a is fixed inside the first body 101 and the other end of the first touch screen 151a is connected to the second body 102. It is fixed. Accordingly, the user may hold and pull the first and second bodies 101 and 102 by hand to expose the display unit which is rolled and accommodated in at least one of the first and second bodies 101 and 102.

Hereinafter, at least one area that is exposed to the outside of the entire area of the first touch screen 151a to allow the user to check visual information is defined as a 'display area', and an area excluding the display area is defined. This is defined as the 'rest region'.

The controller 180 may detect at least one of the display area and the remaining area by using the sensing unit 140 or the deformation detection means. Based on the detection result, the controller 180 can control the first touch screen 151a to output the screen information while the display area is turned on and to maintain the remaining area off.

The display area displays (outputs) information processed by the mobile terminal 100 in the open state. For example, the display area may display execution screen information of an application program driven in the mobile terminal 100, or user interface (UI) and graphical user interface (GUI) information according to the execution screen information.

The first and second touch screens 151a and 151b may include a touch sensor that senses a touch on the touch screen to receive a control command by a touch method. Using this, when a touch is made with respect to the touch screen, the touch sensor may sense the touch, and the controller 180 may generate a control command corresponding to the touch based on the touch sensor. The content input by the touch method may be letters or numbers or menu items that can be indicated or designated in various modes.

Meanwhile, the touch sensor is formed of a film having a touch pattern and disposed between the window 151a and the display (not shown) on the rear surface of the window 151a or directly patterned on the rear surface of the window 151a. May be Alternatively, the touch sensor may be integrally formed with the display. For example, the touch sensor may be disposed on a substrate of the display or provided in the display.

As such, the display unit may form a touch screen together with the touch sensor, and in this case, the touch screen may function as the user input unit 123 (see FIG. 1). In some cases, the touch screen may replace at least some functions of the user input unit.

Meanwhile, a first user input unit 123a is disposed on the first body 102. However, the present invention is not necessarily limited thereto, and the position of the first user input unit 123a may be changed.

The control command for the first touch screen 151a is received from the first user input unit 123a. More specifically, when a push input is applied to the first touch screen 151a in the open state, the first touch screen 151a is switched to an activated state. That is, the first user input unit 123a may be a home button for turning on and off the first touch screen 151a.

The first user input unit 123a includes a button disposed on a front surface of the first body 101 and configured to receive a push input, and a fingerprint scanner arranged to overlap with the button to recognize a fingerprint of a contacting finger. do.

The button is exposed to the outside from the front of the terminal, it is made to receive a push input of the first function. The first function may be a function of displaying predetermined screen information on the display area. For another example, when a user applies a push input to the button while the web page screen is displayed on the display area, the web page screen of the display area may be converted to a home screen page. As another example, when the home screen page is output to the first touch screen 151a and the home screen page is composed of a plurality of home screen pages, the home screen page may be switched by a push input applied to the button. have.

The first user input unit 123a may be configured to scan a fingerprint from a finger of the user applying the push along with the push input applied. More specifically, a fingerprint scanner module is mounted on one surface of the button (upper surface in this example), thereby recognizing a fingerprint of a finger in contact with the button. The button is slidably formed by the push, thereby pressing the switch. The controller detects the push input when the switch is pressed to process the corresponding control command.

However, the present invention is not necessarily limited to the above structure. For example, the push button may be replaced with a touch button. More specifically, the fingerprint scanner module may be disposed on the upper surface of the touch button. Therefore, in the example described below, the push input through the push button may be replaced with the touch input through the touch button.

The fingerprint scanner module may be utilized as a function key associated with power on and off. For example, when the button of the first user input unit 123a is pushed while the terminal is powered off, fingerprint recognition is performed while power is supplied to the fingerprint scanner module. The terminal determines whether the recognized fingerprint corresponds to a pre-stored user's fingerprint, and if so, continues the power on and booting of the terminal. In this way, as the power on command of the terminal is made in two stages (fingerprint scanner power on and terminal power on), the current consumption may be smaller. That is, a security function according to fingerprint recognition is provided to the power-on operation, but the fingerprint scanner module can be turned off together with the terminal body instead of being continuously turned on.

Furthermore, in this case, since the user turns on the terminal, when the power-on and terminal booting are completed, the display area may directly enter the home screen page without passing through the lock screen.

In addition, if the recognized fingerprint does not correspond to the fingerprint of the user, power on and booting of the terminal are stopped. In this case, the terminal may output a warning message indicating that the user's fingerprint is not. For example, the warning message may be configured to give a lighting effect to the front of the terminal for a predetermined time or output an effect sound.

As another example, in a lock mode in which a lock screen is output to the display area, when a push input is applied to the first user input unit 123a, the lock screen may be switched to a home screen page while being unlocked. In this case, the first user input unit 123a may be a hot key for unlocking.

However, the unlocking is performed only when the fingerprint scanner performs fingerprint recognition on an object contacting the fingerprint scanner for push, and the recognized fingerprint corresponds to a pre-stored user's fingerprint. During fingerprint recognition, a notification message indicating that fingerprint is being recognized may be output on the second touch screen 151b of the terminal.

The first body 101 and the second body 102 may move in a direction away from each other by a user gesture, or may move in a direction closer to each other.

For example, the first and second bodies 101 and 102 may be spaced apart from each other based on a tension applied in a direction crossing the first direction D1 in the locked state. The first touch screen 151a is exposed between 101 and 102. Exposed at least one area of the first touch screen 151a stored in the guide unit out of the guide unit is defined as 'roll-out'. The closed state may be switched to the open state by the roll out.

On the contrary, when the first body 101 and the second body 102 move in a direction closer to each other, at least one area of the first touch screen 151a exposed outside the guide unit is accommodated in the guide unit. This is defined as 'roll-in'. The open state may be switched to the closed state by the roll-in.

When switching from the closed state to the open state, the controller 180 determines whether to release the locked state based on the fingerprint scanner recognizing the fingerprint of the finger.

If the recognized fingerprint does not exist or is inconsistent with a pre-stored user's fingerprint, a lock screen configured to receive a password for unlocking while maintaining the lock state is output to the display area. The password may be set in various forms such as a password set by a user or a pattern.

When the lock screen is output to the display area, guide information indicating that the lock state is maintained, and guide information indicating that fingerprint recognition is required may be output to the second touch screen 121b. In the state in which the lock screen is output (or the lock mode), the first touch screen 151a may be a state in which only a touch input related to an operation of releasing the lock state is possible. The operation of releasing the locked state may be an operation of inputting a pattern or a password set by a user.

In contrast, when the recognized fingerprint corresponds to a pre-stored fingerprint of the user, the controller 180 switches the locked state to the released state and outputs a home screen page to the display area. Guide information for guiding that fingerprint recognition is successful may be output to the second touch screen 121b.

Here, the home screen page may also be referred to as an idle screen, and a touch input to the display area is possible. In this case, the first user input unit 123a may be a hot key for unlocking.

The home screen page may be output on the display unit 251 when the terminal is in the standby state. More specifically, the home screen page may display an icon or a widget of an application installed in the mobile terminal. In addition, a plurality of home screen pages may be configured according to a user's selection or the number of applications installed in the terminal.

As such, switching to the home screen page may be performed in a form of returning to the home screen page in a state in which a specific application is being executed, rather than a lock mode. For example, when the web page is output to the display area, the first user input unit 123a may be pushed to return to the home screen page. That is, the first user input unit 123a may operate as a home key for performing a control command to return to the home screen page.

The display area, which is turned off by the roll out, is turned on and the screen information is displayed. However, the locked state is released or maintained according to whether the fingerprint matching the user fingerprint previously stored in the first user input unit 123a is recognized. As a result, the user may control the rollable terminal to output different screen information upon roll out.

Meanwhile, when the lock is released in the open state, a plurality of icons related to the execution of different applications may be displayed on the second touch screen 151b. In other words, when the home screen page is output to the display area, the controller 180 may output a plurality of icons to the second touch screen 151b.

The plurality of icons may be associated with an application that was selected by the user or recently executed. When the plurality of icons are associated with applications preset by the user, the type of the preset application may be reset by user input.

When a touch is applied to any one of the plurality of graphic objects in the open state, the controller 180 executes an application corresponding to the one icon and outputs the execution screen to the display area. do. For example, if a touch is applied to any one of the icons displayed on the second touch screen 151b while the home screen page is output to the display area, the home screen page is executed by the application corresponding to the one. You are switched to the screen.

When the execution screen is displayed on the display area, the icons disappear from the second touch screen 151b, and graphic objects corresponding to a function related to the application are displayed on the second touch screen.

As the roll out is performed in the closed state, the display area is changed from a long rectangular shape to a long rectangular shape. When the user grips the terminal using the first and second bodies 101 and 102, when a graphic object is displayed at the center of the display area, it is difficult for the user to apply a touch to the graphic object. In order to prevent this inconvenience, when the execution screen is displayed on the display area, the rollable mobile terminal according to the present invention replaces at least one of the graphic objects to be included in the execution screen with the second touch screen instead of the display area. The display may be displayed on the display panel 151b (or may be overlapped on the display area and the second touch screen 151b). As a result, the user may execute a function related to the execution screen by using the hand holding the terminal.

The second touch screen 151b serves as an information provider for providing simple information in the locked state, provides a predetermined icon for quick execution in the open state, or displays screen information being output to the display area. It can provide an interface to control the.

According to the present invention, since the first and second touch screens 151a and 151b operate in cooperation with each other, the mobile terminal can effectively output information necessary for the user.

On the other hand, when the open state is switched to the locked state by the roll-in in the unlocked state, the controller 180 locks the terminal. That is, the terminal is switched to the locked state.

The second user input unit 123b may be disposed on the first body. However, these configurations are not limited to this arrangement. These configurations may be excluded as needed or arranged on the other side. For example, the second user input unit 123b may be provided on the rear side or the side of the first body 101.

The second user input unit 123b may operate as a size adjusting key of the display area for expanding or reducing the size of the display area. More specifically, the second user input unit 123b is formed along the longitudinal direction of the first body 101 and is exposed to the front of the terminal body. The second user input unit 123b includes keys disposed up and down, respectively, and is configured to receive a user input for rotating the driving unit clockwise or counterclockwise.

Although not shown in the drawings, the components described above in FIG. 1 may be provided in any one of the front, side, rear, and the inside of the terminal body. For example, a first camera may be disposed on the rear surface of the first body 101, and a second camera may be disposed on the rear surface of the second body 102.

In the above, the structure of the mobile terminal 100 has been mainly described. Hereinafter, the control operation according to the structure of the mobile terminal will be described in detail.

4 is a flowchart illustrating a control method according to the present invention.

First, the controller 180 sets a portion of the touch screen 151 exposed out of the body as a display area in which visual information is output (S410).

At least one area of the entire area of the touch screen 151 exposed to the outside to allow a user to check visual information is set as a display area, and an area except the display area is set as the remaining area.

The controller 180 may sense at least one of the display area and the remaining area by using the sensing unit 140.

Since the remaining area is accommodated in the first body 101, the visual information output from the remaining area is not visible to the user. In consideration of this, visual information may not be output to the remaining area of the touch screen 151.

For example, while visual information related to information processed by the mobile terminal 100 is output to the display area, an outer image surrounding the visual information may be output to the remaining area. The outer image may be filled with a specific series of colors (eg, black).

As another example, the controller 180 may output the screen information while the display area is turned on, and control the touch screen 151 so that the remaining area is turned off. In this example, only a part of the touch screen 151 is driven, so that the display 151 can be driven more efficiently than the previous example in which the entire display 151 is driven, thereby achieving a power saving effect.

Next, in response to a user input, the controller 180 drives the driving unit such that at least a part of the touch screen is drawn out of the body or drawn into the body by the rotation of the rotating shaft (S430).

In order to receive the user input, a user input unit may be disposed on one surface of the first body 101. The user input unit may operate as a size adjusting key of the display area that enlarges or reduces the size of the display area. For example, the user input unit may include an enlargement key having a function of expanding a size of a display area and a reduction key having a function of reducing a size of a display area.

The user input unit may be implemented not only by the hardware key described above, but also by a software key (or a virtual button) output from at least one region of the touch screen 151.

According to a user input applied to the user input unit, at least one of the rotation direction and the amount of rotation of the drive unit is changed. Specifically, the controller 180 rotates the driving unit b clockwise or counterclockwise based on a user input, and adjusts the amount of rotation differently according to a user input.

For example, when the enlarged key is pressed once, the drive unit 220 rotates clockwise by a preset amount, and when the enlarged key is pressed twice, the drive unit 220 rotates clockwise by twice the preset amount. Can rotate. If the enlarged key is continuously pressed, the driving unit 220 may rotate clockwise until the pressing is terminated or the display area reaches a maximum value.

For another example, the controller 180 controls the driving unit 220 so that the display area is at the maximum size when a first user input that satisfies the first condition is applied to the user input part, and the controller 180 satisfies the second condition. 2, when the user input is applied to the user input unit, the driving unit 220 may be controlled to accommodate the touch screen 151 in the first body 101.

Thus, the mobile terminal 100 can finely adjust the size of the display area using the driving unit 220 and can provide a user interface that can be easily adjusted so that the display area becomes a predetermined size.

Next, when the display area is changed by the rotation of the rotation axis, the controller 180 controls the touch screen 151 to output different screen information to the display area according to the size of the display area (S450).

For example, if the display area is changed from the first area to the second area by a user input while the first execution screen of the application is displayed on the display area, the controller 180 may determine the size of the application based on the size of the second area. A second execution screen may be output to the display area.

The application is a concept including a widget, a home launcher, etc., and means any type of program that can be run in the terminal. Accordingly, the application may be a program that performs a function of a web browser, video playback, message transmission, reception, schedule management, and application updating.

The size of the second area varies according to the user input applied to the user input unit, and the second execution screen of the application displayed on the second area also varies according to the size of the second area.

According to the above example, even if substantially the same information is provided in any application, the interface for providing the information varies according to the size of the display area. As the display area is smaller, only the most important information is selectively displayed. As the display area is larger, the next order information is gradually displayed. The user may be provided with an optimal interface by changing the display area according to the situation.

As another example, when an event occurs in the second application while the execution screen of the first application is displayed on the display area, the controller 180 outputs guide information indicating the event to the display area and outputs the guide information. When the user input unit is pressed in a predetermined manner, the driving unit 220 may be driven such that the display area becomes a second area larger than the first area in the first area.

The occurrence of the event may be, for example, when there is a missed call, when there is an application to be updated, when a message arrives, charging, power on, power off, power off, display activation keys of the terminal. LCD awake keys, alarms, incoming calls, missed notifications, and the like.

As another example, when specific information is received through the wireless communication unit of the terminal, an event occurs in an application related to the specific information, and the controller detects this. Or, if there is an item input by the user on the schedule management, when the date is a date corresponding to the item, it means that an event occurs in the schedule management application.

In this case, an execution screen of the first application is displayed in a first portion corresponding to the first region in the second region, and the second application is displayed in a second portion different from the first portion in the second region. The execution screen of is displayed. In other words, the execution screen of the first application is displayed as it is in the displayed portion (or the first portion), and the second portion is displayed in the portion (or the second portion) newly exposed out of the first body 101 by the user input. The execution screen of the application is displayed.

Since the information related to the event is displayed on the extended display area, the user can additionally check the information related to the event while using the previously displayed screen information.

The size of the second area depends on the type of the event. As another example, they may have different sizes according to the type of application in which the event occurs or different sizes depending on the amount of information related to the event.

For example, when a message is received, if the message content is large, the display area may be enlarged. If the message content is small, the display area may be slightly expanded. This effectively uses the battery and prevents the display area from being unnecessarily enlarged.

The preset user input is distinguished from a user input of a general method for using screen information displayed on a larger screen.

For example, if the enlargement key is pressed once while the guide information is output, the display area is expanded by a predetermined amount, and the execution screen of the previously output first application is output to the expanded display area. On the other hand, if a user input of a preset method is input while the guide information is output, the display area is extended from the first area to the second area, and the execution screen of the first application and the execution screen of the second application are displayed together. .

The preset user input may be a user input that simultaneously presses the enlargement key and the reduction key.

Meanwhile, when the user input unit is pressed in the predetermined manner while the execution screen of the first application and the execution screen of the second application are output from the second area, the driving unit 220 is driven and the display area is displayed. The first area is changed from the second area. Accordingly, the execution screen of the second application disappears from the display area. The user can easily check the information related to the event and restore the display area to its original state.

The control method related to the present invention described above may be embodied in various forms as shown in FIGS. 5A to 12. In the embodiment described below, the same or similar reference numerals are assigned to the same or similar configurations as the foregoing examples, and the description is replaced with the first description.

5A to 13 are conceptual diagrams illustrating an example of an operation implemented by the mobile terminal of FIG. 2, and an operation of adjusting a display area according to a user input and controlling information displayed on the display area accordingly.

As an example of such control, referring to FIG. 5A, the output navigation information may vary according to the size of the display area.

The mobile terminal 100 may provide navigation information in real time due to the nature of being portable. In particular, when the user uses the vehicle, the user may fix the mobile terminal 100 to the vehicle and perform driving by using the navigation information output from the mobile terminal 100.

For example, the user may fix the touch screen 151 to face the windshield of the vehicle to check the navigation information indirectly through the information reflected on the windshield, or to direct the touchscreen 151 to the user. By fixing to a point, the navigation information can be directly checked through the information output from the touch screen 151.

The navigation information in the case where the information is displayed indirectly and the case in which the information is directly displayed should be output in a different manner. For example, when the display is indirectly, since information reflected on the glass window is transmitted to the user, the information output on the touch screen 151 should be reversed unlike the general case. Furthermore, when complex information is displayed on the windshield, there is a risk of disturbing the eyes of the user, so information to be delivered to the user should be minimized.

In consideration of such a problem, the mobile terminal 100 according to the present invention adjusts the size of the display area based on a user input applied to the user input unit 123, and different screen information based on the adjusted display area size. Can be output to the display area.

The application may have various modes of conveying information in different ways depending on the size of the display area.

For example, as illustrated in FIG. 5A, when the size of the display area is within the first reference range, the navigation information according to the first mode is output. When the size of the display area is within the second reference range, the second mode is displayed. The navigation information according to the third embodiment may be output. When the size of the display area is within the third reference range, the navigation information according to the third mode may be output. For another example, as illustrated in FIG. 5B, when a user input that satisfies a specific condition is applied, the display area may be the maximum size, and navigation information according to the fourth mode may be output.

Each time the enlargement key is pressed, the controller 180 can execute any one of a plurality of modes preset in the application, and enlarge the display area to a size corresponding to the one of the modes. Since the first to fourth modes are executed sequentially each time the enlargement key is pressed, the display area can be enlarged in stages.

On the contrary, when the reduction key is pressed, since the fourth to the first modes are executed sequentially, the display area can be reduced in stages.

Since a plurality of modes that can be executed and an aspect ratio (or size) of a display area corresponding to each mode are embedded in the application, the controller 180 selects one mode based on information embedded in the application. And drive the drive unit such that the display area has a size corresponding to any one of the above modes. The user input unit 123 receives a user input for selecting any one of the plurality of modes.

Substantially the same information (current position, direction of travel, speed, remaining distance) is output in different ways depending on the mode in which it is executed, and the user presses the user input unit 123 in various ways, thereby allowing any of various modes to be executed. You can simply choose one. In addition, since any one mode is sequentially changed to the other mode each time the user input unit 123 is pressed, a specific mode may be selected according to a situation.

If the display area is adjusted by applying artificial force while driving, there is a risk of an accident. However, since the mobile terminal according to the present invention provides a user interface for easily adjusting the display area by using the user input unit 123 and the driving unit 123, the risk is reduced.

As another example of control, referring to FIG. 6, when an event occurs in a closed state, a notification indicating an event occurrence may occur in at least one of a visual, tactile, and auditory manner.

When the user input unit 123 is pressed while the notification is generated, at least a part of the touch screen 151 stored in the first body 101 is exposed to the display area, and the execution screen of the application where the event occurs is displayed on the display area. Is displayed.

In this case, the size of the display area varies according to the user input applied to the user input unit 123, and the event information is output in a different manner according to the size of the display area.

For example, when a user input of a first method is applied while a notification according to a message is output, the driving unit 220 is driven so that the display area has a size to which the message content can be output.

As another example, when a second type of user input is applied, the driving unit 220 is driven to have a size such that not only the message content but also the reply input window and the virtual keypad can be displayed together.

If the user wants to simply check the message contents, the user may authorize the first type of user input, and if the user wants to quickly reply to the message contents, the user may authorize the second type of user input.

Meanwhile, when a user input of a preset method is applied, the controller 180 may enlarge the display area to different sizes according to the information displayed on the display area. 7A to 11B are conceptual views illustrating an example of an operation of a mobile terminal according to a preset user input.

If the user input unit 123 is pressed in a preset manner while the execution screen of the first application is displayed on the display area, the controller 180 may be the second area larger than the first area in the first area. Drive the drive unit 220.

In this case, an execution screen of the first application is displayed in a first part corresponding to the first area in the second area, and a new screen is displayed in a second part different from the first part in the second area. do.

For example, referring to FIG. 7A, when a user input of a preset method is applied while a message screen including an attachment is displayed, the message screen is displayed in a first portion corresponding to the first area in the second area. The execution screen of the attachment is displayed on a second part different from the first part in the second area.

The size of the second area varies depending on the type of the attached file, and different applications are executed according to the type of the attached file.

For example, as shown in FIG. 7A, if the attachment is a document, an application associated with the document is executed, and a part of the document is output in the second portion. For another example, as shown in FIG. 7B, if the attached file is a video, an application capable of playing the video is executed, and the video playback screen is output in the second part.

The optimum aspect ratio may be preset for each application. The controller 180 searches for an aspect ratio set for the corresponding application while executing an application associated with the attached file, and adjusts the size of the second area based on the found aspect ratio. As a result, the user may be provided with an optimized screen according to the attached file.

Meanwhile, referring to FIG. 8A, the user input unit may be pressed in a predetermined manner while the graphic object associated with the playback function of a certain video is displayed on the display area.

Here, the graphic object associated with the playback function may mean a link connected to a certain video. For example, when a web page is output, a link to a video may be attached to the body of the web page. In general, when a touch is applied to the graphic object, a playback screen of a specific video is output.

If the user input unit is pressed in a predetermined manner while the graphic object is displayed, the controller 180 drives the driving unit such that the display area becomes a second area larger than the first area in the first area. Further, the graphic object is displayed in a first part corresponding to the first area in the second area, and a playback screen of a certain video is displayed in a second part different from the first part in the second area. Control the touch screen. When the display area becomes the second area, the certain video may be automatically played.

In this case, the size of the second area depends on the aspect ratio of the video. Since the vertical length of the display area is fixed and only the horizontal length is different, the controller 180 determines the size of the second area according to the aspect ratio of the video. For example, when the aspect ratio of the video is 16: 9, the size of the second area is determined so that the horizontal length of the second portion is longer than the vertical length, and when the aspect ratio of the video is 9:16, The size of the second region may be determined such that the vertical length of the two parts becomes longer than the horizontal length.

The user can use the video included in the existing screen while using the existing screen as it is.

Meanwhile, the controller 180 senses a control command related to the information displayed on the first part using a touch input applied to the first part, and detects a control command related to the information displayed on the second part. Detect using touch input applied to. That is, the first part and the second part are separate windows, which individually allow a touch input and display an output accordingly. For example, as illustrated in FIG. 8B, the web browser screen output to the first portion may be changed from the first screen to the second screen by a touch input applied to the web browser screen. In this case, the moving picture reproduction screen output from the second portion is output as it is without change.

Meanwhile, referring to FIG. 9A, when an event occurs in the second application while the execution screen of the first application is displayed on the display area, the controller 180 outputs guide information 910 indicating the event to the display area. can do.

When the user input unit is pressed in a predetermined manner while the guide information 910 is output, the controller 180 controls the display unit to be a second area larger than the first area in the first area. Can be driven.

In this case, an execution screen of the first application is displayed in a first portion corresponding to the first region in the second region, and the second application is displayed in a second portion different from the first portion in the second region. The execution screen of is displayed. In other words, the execution screen of the first application is displayed as it is in the displayed portion (or the first portion), and the second portion is displayed in the portion (or the second portion) newly exposed out of the first body 101 by the user input. The execution screen of the application is displayed.

The size of the second area depends on the type of the event. As another example, they may have different sizes according to the type of application in which the event occurs or different sizes depending on the amount of information related to the event.

For example, when a message is received, if the message content is large, the display area may be enlarged. If the message content is small, the display area may be slightly expanded. This effectively uses the battery and prevents the display area from being unnecessarily enlarged.

Meanwhile, as shown in FIG. 9B, when the user input unit is pressed in the predetermined manner while the execution screen of the first application and the execution screen of the second application are output from the second area, the driving unit 220. The display area is changed from the second area to the first area while being driven.

Accordingly, the execution screen of the second application disappears from the display area. The user can easily check the information related to the event and restore the display area to its original state.

Meanwhile, referring to FIG. 10, when the user input unit 123 is pressed in a preset manner while the execution screen of the application is displayed on the display area, the controller 180 has the aspect ratio preset for the application. Drive unit 220 to operate.

The user may adjust the size of the display area by applying an external force, and the display area may have an aspect ratio that the application does not support. In this case, at least a part of the execution screen may be cut out and not displayed on the display area, or visual information may not be displayed on a part of the display area.

The controller 180 drives the driving unit 220 so that the display area has a preset aspect ratio for the application in response to a user input of a preset method so that the display area is appropriately changed to the execution screen.

Meanwhile, referring to FIGS. 11A and 11B, when the user input unit is pressed in a predetermined manner while the execution screen of the first application is displayed on the display area, the control unit 180 displays the display area in the first area. The drive unit is driven to become a second area larger than one area. In addition, the touch screen 151 is controlled to display an execution screen of the first application and an execution screen of a second application different from the first application in the second area.

In this case, the second application corresponds to the most recently executed application, and the size of the second area varies depending on the type of the second application.

For example, as shown in FIG. 11A, when a call is received while the web browser screen 1110 is displayed in the display area, the web browser screen 1110 is switched to the call reception screen 1120.

Thereafter, when a user input of a preset method is applied to the user input unit 123, the display area is extended from the first area to the second area.

In the second area, a call reception screen 1120 is displayed on a first part corresponding to the first area, and an execution screen of a most recently executed application is displayed on a second part different from the first part in the second area. That is, the web browser screen 1110 is displayed.

The user can continue to perform a web browser while performing a phone call.

For example, as illustrated in FIG. 11B, when the video playback screen 1130 is most recently output, the controller 180 may display the display area from the first area to the second area in response to a user input of a preset method. The size of the second area may be determined to fit the video play screen 1130. Accordingly, the call reception screen 1120 and the video reproduction screen 1130 are output together.

12, when the map image is output to the display area, the controller 180 may change the tracking of the map image based on a user input applied to the user input unit 123.

More specifically, when an enlargement command for the display area is received while the map image is displayed at the first scale, the first scale is changed to the second scale and the scaled image is output to the enlarged display area. Since the scale varies according to the user input applied to the user input unit, the user can easily change the map image output on the display area using the user input unit at a desired scale according to the situation.

On the other hand, with the development of mobile terminals, portal companies that provide web pages are divided into mobile versions suitable for mobile terminals and PC versions suitable for fixed terminals. Since charging is generated by the amount of data used in the mobile terminal, the mobile version has a problem that the amount or size of information is smaller than that of the PC version.

When accessing a web page, the mobile terminal 100 according to the present invention may change the type of web page to be displayed according to the size of the display area. Specifically, when the size of the display area is smaller than the reference size, the mobile version of the web page may be accessed. When the size of the display area is larger than or equal to the reference size, the PC version of the web page may be accessed. Thus, the user can use the rollable mobile terminal as a conventional mobile terminal or use a fixed terminal.

The present invention described above can be embodied as computer readable codes on a medium in which a program is recorded. The computer-readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable media include hard disk drives (HDDs), solid state disks (SSDs), silicon disk drives (SDDs), ROMs, RAMs, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, and the like. This also includes implementations in the form of carrier waves (eg, transmission over the Internet). In addition, the computer may include the controller 180 of the terminal. Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
