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 of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection fluorescent light sensor, a mirror reflection fluorescent light sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. 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, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have.

Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, 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 transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen).

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The touch sensor may be a film having a touch pattern and disposed between the window 151a and a display (not shown) on the rear surface of the window 151a, or may be a metal wire . Alternatively, the touch sensor may be formed integrally with the display. For example, the touch sensor may be disposed on a substrate of the display or inside the display.

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

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

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

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

The button is exposed to the outside from the front of the terminal, and receives the push input of the first function. The first function may be a function of causing predetermined display information to be displayed on the display area. In another example, if a user applies a push input to the button while a web page screen is displayed on the display area, the web page screen of the display area may be switched to a home screen page. In another example, when a home screen page is output to the first touch screen 151a and a plurality of home screen pages are formed, the home screen page can be switched by the push input applied to the button have.

The first user input unit 123a may be configured to scan the fingerprint of the user's finger applying the push with the push input. More specifically, a fingerprint scanner module is mounted on one surface (upper surface in this example) of the button, thereby recognizing the fingerprint of the finger contacting the button. The button is slidably formed by the pushing, thereby pushing the switch. When the switch is pressed, the control unit detects the push input and processes the corresponding control command.

However, the present invention is not necessarily limited to the above structure. For example, the push button may be replaced by 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 can be replaced with the touch input through the touch button.

The fingerprint scanner module can be utilized as a function key related to power on / off. For example, if the button of the first user input unit 123a is pushed while the power of the terminal is turned off, power is supplied to the fingerprint scanner module to perform fingerprint recognition. The terminal determines whether the recognized fingerprint corresponds to the fingerprint of the user, and proceeds to power on and boot the terminal when the fingerprint corresponds. As described above, since the power-on command of the terminal is made in two stages (fingerprint scanner power-on and terminal power-on), the consumed current can be reduced. That is, the security function according to the fingerprint recognition is given to the power-on operation, but the fingerprint scanner module can be turned off together with the terminal main body instead of the on-state.

Further, in this case, since the user turns on the terminal, when the power-on and the terminal boot are completed, the display area can directly enter the home screen page without going through the lock screen.

In addition, if the recognized fingerprint does not correspond to the fingerprint of the user, power-on and terminal booting are interrupted. In this case, the terminal may output a warning message that the fingerprint is not the user's fingerprint. The warning message may be, for example, given a lighting effect for a predetermined period of time or outputting an effect sound.

As another example, in the lock mode in which the lock screen is displayed on the display area, when the push input is applied to the first user input unit 123a, the lock screen is unlocked and the lock screen can be switched to the home screen page. In this case, the first user input unit 123a may be a hotkey for unlocking.

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

The first body 101 and the second body 102 may move in a direction away from each other or in a direction in which they approach each other by a user gesture.

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

When the fingerprint scanner is switched 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.

And a lock screen configured to receive a password for unlocking while maintaining the locked state when the recognized fingerprint does not exist or is inconsistent with a fingerprint of a previously stored user. The password may be a password set by the user or may be set in various forms such as a pattern.

When the lock screen is displayed on the display area, guidance 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. The first touch screen 151a may be in a state in which only the touch input related to the operation of releasing the lock state is available in the state in which the lock screen is output (or in the lock mode). The operation of releasing the lock state may be an operation of inputting a pattern or a password set by the user.

Alternatively, if the recognized fingerprint corresponds to the fingerprint of the user, the controller 180 switches the locked state to the released state and outputs the home screen page to the display area. The second touch screen 121b may output guidance information indicating that the fingerprint recognition is successful.

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

The home screen page can be output on the display unit 251 when the terminal is in the standby state. More specifically, an icon (icon) or a widget (wiget) of an application installed in the mobile terminal may be displayed on the home screen page. Further, the home screen page may be composed of a plurality of home screens depending on the user's selection or the number of applications installed in the terminal.

Thus, switching to the home screen page is not a lock mode, but may be a form of returning to a home screen page while a specific application is running. For example, if the first user input unit 123a is pushed while the web page is displayed on the display area, the web page may be reduced to a 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 turned off by the roll-out is turned on and the screen information is displayed, but the locked state is released or maintained depending on whether a fingerprint matching the user fingerprint previously stored in the first user input unit 123a is recognized. Thus, the user can control the rolled-up terminal to output different screen information when the roll-out is performed.

Meanwhile, when the lock is released in the open state, a plurality of icons related to execution of different applications may be displayed on the second touch screen 151b. In other words, when the home screen page is displayed on 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 selected by a user or executed recently. If the plurality of icons are associated with applications preset by the user, the type of the predetermined application may be reset by user input.

When a touch is applied to one of the plurality of graphic objects in the open state, the control unit 180 executes an application corresponding to the one of the plurality of graphic objects, 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 being output to the display area, the home screen page may be executed Screen.

When the execution screen is output to the display area, the icons disappear on the second touch screen 151b, and graphic objects corresponding to functions 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 vertically long rectangular shape to a horizontally long rectangular shape. When the user holds the terminal using the first and second bodies 101 and 102, it is difficult for the user to apply a touch to the graphic object when the graphic object is displayed at the center of the display area. In order to prevent such an inconvenience, when the execution screen is displayed in the display area, the rolled mobile terminal according to the present invention may display at least one of the graphic objects to be included in the execution screen, (Or may be displayed on the display area and the second touch screen 151b in an overlapped manner). Thereby, the user can execute the 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. The second touch screen 151b provides a predetermined icon for quick execution in the open state, Can be provided.

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

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

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

The second user input unit 123b may operate as a size adjustment key of a display area for enlarging 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 exposed to the front surface of the terminal body. The second user input unit 123b includes keys disposed on the upper and lower sides, respectively, and receives the user input for rotating the drive unit in the clockwise direction or in the counterclockwise direction.

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

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

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

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

At least one area in which the user can see visual information is exposed as the display area and the area other than the display area is set as the remaining area.

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

Since the remaining area is accommodated in the first body 101, the time information output from the remaining area is not shown to the user. In view of this, the time information may not be output to the remaining area of the touch screen 151. [

For example, in a state in which time information related to information processed by the mobile terminal 100 is output to the display area, an outline image surrounding the time information may be output to the remaining area. The outline image may be filled with a specific sequence of colors (e.g., black).

In another example, the controller 180 may control the touch screen 151 such that the display area is turned on to output screen information and the remaining area is turned off. In this example, since only a part of the touch screen 151 is driven, the display 151 can be efficiently driven as compared with the previous example in which the entire display 151 is driven, thereby achieving a power saving effect.

Next, in response to the user's 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 rotation of the rotation axis (S430).

In order to receive the user input, a user input unit may be disposed on one side of the first body 101. The user input unit may operate as a size adjustment key of a display area for enlarging or reducing the size of the display area. For example, the user input unit may include an enlarging key for enlarging the size of the display area and a reducing key for reducing the size of the display area.

The user input unit may be implemented by a hardware key or a software key (or a virtual button) output from at least one area of the touch screen 151.

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

For example, when the enlargement key is pressed once, the drive unit 220 rotates clockwise by a predetermined amount, and when the enlargement key is pressed twice, the drive unit 220 is rotated clockwise . When the enlargement key is continuously pressed, the driving unit 220 can be rotated clockwise until the pressurization ends or the display area reaches a maximum value.

For example, when the first user input satisfying the first condition is applied to the user input unit, the control unit 180 controls the driving unit 220 to maximize the display area, When the user input is applied to the user input unit, the driving unit 220 can be controlled so that the touch screen 151 is housed in the first body 101.

Accordingly, 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 has 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 so that different screen information is displayed on the display area according to the size of the display area (S450).

For example, when the display area is changed from the first area to the second area by user input while the first execution screen of the application is being displayed in the display area, the controller 180 controls the application The second execution screen can be output to the display area.

The application is a concept including a widget, a home launcher, and the like, and refers to all types of programs that can be run on the terminal. Accordingly, the application may be a program that performs a function of a web browser, a moving image playback, a message transmission / reception, a schedule management, and an application update.

The size of the second area is changed according to the user input applied to the user input unit and the second execution screen of the application displayed in the second area is changed according to the size of the second area.

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

In another example, when an event is generated in the second application while the execution screen of the first application is displayed in the display area, the controller 180 outputs guide information for notifying the event to the display area, The driving unit 220 may be driven so that the display area is a second area larger than the first area in the first area.

The occurrence of an event can be detected, 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, An LCD awake key, an alarm, an incoming call, a missed notification, 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 control unit senses the event. Or when there is an item entered by the user on the schedule management, when the date corresponds to the item, the event occurs in the schedule management application.

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 second part different from the first part in the second area is displayed in the second part 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 portion (or the second portion) newly exposed by the user input outside the first body 101 has the second The execution screen of the application is displayed.

Since the information related to the event is displayed in the extended display area, the user can additionally confirm the information related to the event while using the screen information that has been output previously.

The size of the second area varies depending on the type of the event. As another example, the event may have a different size depending on the type of the application in which the event is generated, or may have different sizes depending on the amount of information related to the event.

For example, when a message is received, the display area may be enlarged if the message content is large, and the display area may be enlarged if the message content is small. As a result, the battery is efficiently used, and the display area is prevented from being enlarged unnecessarily.

The user input of the predetermined method is distinguished from the user input of the general method for using the screen information that has been displayed in the larger screen.

For example, if the enlargement key is pressed once during the output of the guide information, the display area is expanded by a preset amount, and the execution screen of the first application that has been output is output to the expanded display area. Alternatively, if a predetermined user input is input while the guide information is output, the display area is expanded 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 user input of the preset method may be a user input which 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 being output in the second area, the driving unit 220 is driven, The second region is changed to the first region. Accordingly, the execution screen of the second application disappears from the display area. The user can easily confirm the information related to the event and restore the display area to the 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. Hereinafter, in the illustrated embodiment, the same or similar reference numerals are given to the same or similar components as those of the preceding example, and the description is replaced with the first explanation.

FIGS. 5A to 13 are conceptual diagrams illustrating operations for adjusting a display area according to user input, and thereby controlling information displayed in the display area, as an example of operations performed by the mobile terminal of FIG.

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

The mobile terminal 100 can provide navigation information in real time due to its portable nature. In particular, when the user uses the vehicle, the user can operate the mobile terminal 100 by fixing the vehicle to the vehicle and using the navigation information output from the mobile terminal 100.

For example, the user fixes the touch screen 151 to the windshield window of the vehicle to indirectly check the navigation information through the information reflected on the windshield, or controls the touch screen 151 to the user So that 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 indirectly displayed and the information which is directly displayed should be output in a different manner. For example, when the information is indirectly displayed, the information reflected on the window is transmitted to the user, so that information to be output to the touch screen 151 should be inverted unlike the general case. Furthermore, when complicated information is displayed on the windshield, there is a possibility that the user's gaze may be interrupted. Therefore, information to be transmitted to the user should be minimized.

In consideration of this problem, the mobile terminal 100 according to the present invention adjusts the size of the display area based on the user input applied to the user input part 123, and based on the size of the adjusted display area, 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 shown in FIG. 5A, when the size of the display area is within the first reference range, navigation information according to the first mode is output. When the size of the display area is within the second reference range, If the size of the display area is within the third reference range, the navigation information according to the third mode can be output. In another example, as shown in FIG. 5B, when a user input satisfying a specific condition is applied, the display area becomes the maximum size, and navigation information according to the fourth mode can be output.

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

Conversely, when the reduction key is pressed, the display area can be stepped down because the fourth and first modes are sequentially executed.

Since the plurality of modes that can be executed in the application and the screen ratio (or size) of the display area corresponding to each mode are built in, the control unit 180 determines which one of the modes And drive the drive unit such that the display area has a size corresponding to any one of the modes. The user input unit 123 receives a user input for selecting one of the plurality of modes.

Substantially the same information (current position, traveling direction, speed, remaining distance) is output in different ways depending on the mode in which it is executed, and the user can press the user input 123 in various manners, You can simply choose one. Further, since one mode is sequentially changed to another mode every time the user input unit 123 is pressed, a specific mode can be selected according to the situation.

If an artificial force is applied during the operation to adjust the display area, there is a risk of accidents. However, since the mobile terminal according to the present invention provides a user interface that can easily adjust the display area using the user input unit 123 and the driving unit 123, the risk is reduced.

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

When the user input unit 123 is pressed during the notification, at least a part of the touch screen 151 stored in the first body 101 is exposed as a display area, and an execution screen of an application in which an event occurs in the display area Is displayed.

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

For example, if a first type of user input is applied while a notification is received according to message reception, the driving unit 220 is driven such that the display area has a size at which the contents of the message can be output.

As another example, when the user input of the second mode is applied, the drive unit 220 is driven so that not only the contents of the message but also the size of the reply input window and the virtual keypad can be displayed together.

If the user wishes to simply check the contents of the message, he or she can apply the user input of the first scheme and apply the user input of the second scheme if the user wishes to quickly reply to the message contents.

On the other hand, if a preset user input is applied, the controller 180 may enlarge the display area to different sizes according to the information displayed in the display area. FIGS. 7A and 11B are conceptual diagrams illustrating an operation example of a mobile terminal according to a predetermined user input.

When the user input unit 123 is pressed in a predetermined manner while the execution screen of the first application is displayed in the display area, the controller 180 controls the display area to be a second area larger than the first area in the first area And drives the driving 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 predetermined type of user input is applied while a message screen including an attached file is displayed, in the first area corresponding to the first area in the second area, And an execution screen of the attached file is displayed in 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 depending on the type of the attached file.

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

An optimal aspect ratio may be preset for each application. The control unit 180 searches for an aspect ratio set for the application while executing an application associated with the attached file, and adjusts the size of the second area based on the screen ratio. Thus, the user can receive an optimized screen according to the attached file.

Meanwhile, referring to FIG. 8A, the user input portion may be pressed in a predetermined manner while a graphic object associated with a playback function of a moving image is displayed in the display region.

Here, the graphic object associated with the playback function may refer to a link to any movie. For example, when a web page is output, a link to the video may be attached to the body of the web page. Generally, when a touch is applied to the graphic object, a playback image of a specific moving image is output.

The controller 180 drives the driving unit such that the display area is a second area larger than the first area in the first area when the user input part is pressed in a preset manner while the graphic object is being displayed. In addition, the graphic object may be displayed in a first portion corresponding to the first region in the second region, and the reproduction screen of any moving picture may be displayed in a second portion different from the first portion in the second region. Control the touch screen. When the display area becomes the second area, any of the moving pictures can be automatically reproduced.

At this time, the size of the second area varies depending on the aspect ratio of the moving picture. Since the vertical length of the display area is fixed and only the horizontal length is changed, the controller 180 determines the size of the second area according to the aspect ratio of the moving image. For example, when the aspect ratio of the moving picture is 16: 9, the size of the second area is determined such that the width of the second part is longer than the length of the second area. If the aspect ratio of the moving picture is 9:16, The size of the second area can be determined such that the vertical length of the two parts is longer than the horizontal length.

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

On the other hand, the control unit 180 senses a control command related to the information displayed on the first part using a touch input applied to the first part, and outputs a control command related to the information displayed on the second part to the second part By using a touch input applied to the touch panel. That is, the first portion and the second portion are separate windows that allow individual touch input and display the output accordingly. For example, as shown in FIG. 8B, the web browser screen displayed on the first portion may be changed from the first screen to the second screen by touch input on the web browser screen. In this case, the moving picture reproduction screen outputted from the second part is outputted without change.

9A, when an event occurs in the second application while the execution screen of the first application is displayed in the display area, the controller 180 outputs guidance information 910 for notifying the event to the display area can do.

If the user input portion is pressed in a preset manner while the guide information 910 is being output, the controller 180 controls the driving unit 220 such that the display region is a second region larger than the first region in the first region, .

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 second part different from the first part in the second area is displayed in the second part 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 portion (or the second portion) newly exposed by the user input outside the first body 101 has the second The execution screen of the application is displayed.

The size of the second area varies depending on the type of the event. As another example, the event may have a different size depending on the type of the application in which the event is generated, or may have different sizes depending on the amount of information related to the event.

For example, when a message is received, the display area may be enlarged if the message content is large, and the display area may be enlarged if the message content is small. As a result, the battery is efficiently used, and the display area is prevented from being enlarged unnecessarily.

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 being output from the second area, The display area is changed from the second area to the first area.

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

10, when the user input unit 123 is pressed in a predetermined manner while the execution screen of the application is displayed on the display area, the control unit 180 displays the application screen in the display area, Driving unit 220 is driven.

The user can adjust the size of the display area by applying an external force. The display area may have an aspect ratio not supported by the application. In this case, at least a part of the execution screen may be cut off and not displayed in the display area, or the time information may not be displayed in a part of the display area.

The control unit 180 drives the driving unit 220 such that the display area has a predetermined aspect ratio in response to the user input of the predetermined mode so that the display area is appropriately changed to the execution screen.

11A and 11B, when the user input portion is pressed in a preset manner while the execution screen of the first application is displayed in the display area, the controller 180 controls the display area And drives the driving unit to be in a second region larger than the first region. Further, the touch screen 151 is controlled such that an execution screen of the first application and an execution screen of a second application different from the first application are displayed in the second area.

At this time, 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 telephone call is received while the web browser screen 1110 is being displayed in the display area, the web browser screen 1110 is switched to the telephone receiving screen 1120.

Thereafter, when a predetermined type of user input is applied to the user input unit 123, the display area is expanded from the first area to the second area.

A call receiving screen 1120 is displayed in a first part corresponding to the first area in the second area and a second part different from the first part in the second area is displayed in a first part corresponding to the first area, I.e., a web browser screen 1110 is displayed.

The user can carry out the existing web browser operation while performing the telephone conversation.

11B, if the moving picture reproduction screen 1130 is outputted most recently, the controller 180 controls the display area in the first area in response to the predetermined user input, The size of the second area may be determined to fit the moving picture playback screen 1130. Accordingly, the telephone receiving screen 1120 and the moving picture reproducing screen 1130 are output together.

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

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

Meanwhile, due to the development of mobile terminals, portal vendors providing web pages provide a web page classified into a mobile version suitable for a mobile terminal and a pc version suitable for a fixed terminal. Since the mobile terminal generates billing by the amount of data to be used, the mobile version has a problem that the amount and 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 the 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 is connected to the web page, and when the size of the display area is larger than or equal to the reference size, the user can access the web page of the PC version. Thus, the user can use the rolled mobile terminal as an existing mobile terminal or use it as a fixed terminal.

The present invention described above can be embodied as computer-readable codes on a medium on 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 the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
