Description:
TECHNICAL FIELD 
     The present specification relates to a bended display device having a main region facing the front side of the device and a sub-region of a prescribed curvature extended from the main region and a method of controlling therefor, and more particularly, to a bended display device controlling the scroll speed of event information displayed on the sub-region according to a posture of the device and a method of controlling therefor. 
     BACKGROUND ART 
     Various electronic devices are used in our daily life with the help of the development of a semiconductor technology and a communication technology. Among the various electronic devices, a display device capable of watching and listening multimedia is most widely used. 
     Recently, a foldable display to which flexibility is provided by replacing a glass plate around liquid crystal of an LCD (liquid crystal display), an LED (light emitting diode), an OLED (organic LED), and an AMOLED (active matrix OLED) with a plastic film receives attention as a display used for a device. The display is divided into a bended display capable of maintaining a bended shape in a manner of being connected to a main body of a device and a flexible display capable of being freely folded and unfolded. 
     When the bended display is connected to the main body of the device, the bended display may have a main region facing the front side of the device and a sub-region having a prescribed curvature in a manner of being extended from the main region. A function of the device can be displayed and managed by linking information on the main region with information on the sub-region. In particular, the sub-region of the bended display can be used as a function region and a display region. For example, various informations such as event information corresponding to an application of the main region, attachment information, status information, control information, and the like can be provided via the sub-region. If it is necessary to control a screen of the main region, it is able to control a function on the screen by controlling the sub-region. 
     Meanwhile, a user of the device may or may not pay attention to various informations displayed on the sub-region. In particular, when the user of the device pays attention to information displayed on the sub-region, the user may pay attention to the information displayed on the sub-region as much as the extent not affecting the use of an application displayed on the main region. Hence, it is necessary to provide the user with a method of displaying the information displayed on the sub-region in association with an action of the device user. 
     DISCLOSURE OF THE INVENTION 
     Technical Task 
     The present specification is designed by recognizing the aforementioned related art. An object of the present specification is to provide a bended display device capable of controlling the scroll speed of event information displayed on a sub-region according to a posture of the device and a method of controlling therefor. 
     Technical Solution 
     To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described, according to one embodiment, a bended display device includes a bended display including a main region facing the front side of the device and a sub-region having a prescribed curvature in a manner of being extended from the main region, a tilt sensor capable of sensing a posture of the device, and a control unit configured to control a function of the device, the control unit configured to display information on an event (hereinafter, event information), which is generated in the middle of executing an application for displaying a screen on the main region, on the sub-region, the control unit configured to control the scroll speed of the event information displayed on the sub-region in a manner of associating the scroll speed with the posture of the device sensed via the tilt sensor. 
     According to one embodiment of the present specification, if the posture of the device is tilted in a manner that a direction at which the sub-region is facing is tilted to a direction at which the main region is facing, the control unit can increase the scroll speed of the event information displayed on the sub-region. In this case, the control unit can increase the scroll speed in proportion to a tilted level of the posture of the device. And, if the direction at which the main region is facing is tilted to the direction at which the sub-region is facing, the control unit can decrease the scroll speed of the event information displayed on the sub-region. 
     According to one embodiment of the present specification, if the posture of the device is tilted in a manner that a direction at which the sub-region is facing is tilted to a direction at which the main region is facing, the control unit can control the scroll of the event information displayed on the sub-region to be started. 
     According to one embodiment of the present specification, if the posture of the device is tilted in a manner that a direction at which the sub-region is facing is tilted to a direction at which the main region is facing, the control unit can control the event information displayed on the sub-region to be scrolled in a direction orthogonal to a direction in which the posture of the device is tilted. 
     The bended display according to the present specification can output an input signal to the control unit by sensing a contact of a user. If the user touches the sub-region while the event information displayed on the sub-region is scrolled, the control unit can stop scrolling the event information displayed on the sub-region. 
     According to one embodiment of the present specification, the control unit can maintain the scroll of the event information displayed on the sub-region in a paused state while the user maintains the touch touched on the sub-region. 
     According to a different embodiment of the present specification, if the user retouches the sub-region after the scroll of the event information displayed on the sub-region is paused, the control unit can control the scroll of the event information displayed on the sub-region to be started again. 
     According to a further different embodiment of the present specification, if the user sweeps the touch in a certain direction while the touch touched on the sub-region is maintained, the control can control contents of the event information displayed on the sub-region to move in the direction to which the touch is swept. 
     Meanwhile, if the posture of the device is returned to a posture at the time of generating the event information, the control unit can stop displaying the event information on the sub-region. 
     According to one embodiment of the present specification, if the application for displaying the screen on the main region corresponds to an application for playing digital media, the control unit can control a volume of the digital media to be reduced from the timing at which the posture of the device sensed by the tilt sensor is tilted. 
     According to one embodiment of the present specification, if the application for displaying the screen on the main region corresponds to an application for playing digital media, the control unit can control the playback of the digital media to be stopped from the timing at which the posture of the device sensed by the tilt sensor is tilted. 
     According to one embodiment of the present specification, if the application for displaying the screen on the main region corresponds to an application for playing digital media using real-time data received from the external, the control unit can store the data of the digital media received in real-time from the timing at which the posture of the device sensed by the tilt sensor is tilted. 
     In this case, if the posture of the device is returned to a posture at the time of generating the event information, the control unit can stop storing the data. And, the control unit can display information related to the stored data on the sub-region. Moreover, if the stored data include images, the control unit can display at least one of the stored images on the sub-region as a thumbnail. In this case, the thumbnail may correspond to a plurality of thumbnails arranged at the sub-region according to the passage of time. The bended display can output an input signal to the control unit by sensing a contact of a user. Hence, if the user touches one of a plurality of the thumbnails, the control unit can play digital media from a part corresponding to the touched thumbnail among the stored data. 
     To further achieve these and other advantages and in accordance with the purpose of the present invention, according to a different embodiment, a method of controlling a bended display device, which includes a bended display containing a main region facing the front side of the device and a sub-region having a prescribed curvature in a manner of being extended from the main region and a tilt sensor capable of sensing a posture of the device, includes the steps of displaying information on an event (hereinafter, event information), which is generated in the middle of executing an application for displaying a screen on the main region, on the sub-region, monitoring the posture of the device via the tilt sensor, and controlling the scroll speed of the event information displayed on the sub-region in a manner of associating the scroll speed with the posture of the device.

     BEST MODE 
     Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. While embodiments are concretely described with reference to the attached diagrams and the contents written on the diagrams, the present specification may be non-restricted or non-limited to the embodiments. 
       FIG. 1  is a perspective diagram for a bended display device according to one embodiment of the present specification. 
     Referring to  FIG. 1 , it is able to check a bended display  110  included in a device  100  according to the present specification. The bended display  110  includes a main region  111  facing the front side of the device  100  and a sub-region  112  having a prescribed curvature in a manner of being extended from the main region  111 . 
     In the embodiment shown in  FIG. 1 , although the sub-region  112  is positioned at the right side of the device on the basis of the front side of the device  100  for example, the bended display  110  according to the present specification can be implemented in various shapes. For example, the sub-region  112  can be positioned at one side among the left side, the upper side, and the lower side. The bended display  110  may have the sub-region  112  positioned at least two positions selected from the group consisting of the right side, the left side, the upper side, and the lower side. 
     Since the bended display  110  uses a plastic board rather than a generally used glass plate, the bended display can be formed using a processor manufactured in low temperature instead of a legacy processor to prevent damage of the board. The bended display  110  provides flexibility capable of being folded and unfolded by replacing a glass plate around liquid crystal of an LCD (liquid crystal display), an LED (light emitting diode), an OLED (organic LED), and an AMOLED (active matrix OLED) with a plastic film. The bended display  110  is thin, light, and shock-resistant. Moreover, as mentioned in the foregoing description, since the bended display is bendable and foldable, it may be able to manufacture the bended display in various shapes. 
     The bended display  110  may have an active matrix screen of a specific screen size (e.g., 3 inches, 4 inches, 4.65 inches, 4.8 inches, 5 inches, 6.5 inches, 7.7 inches, 8.9 inches, 10.1 inches, etc.) depending on a size of the device  100 . The sub-region  112  can be connected with the device  100  in a manner that the curvature of the sub-region  112  is folded with a radius of curvature equal to or less than a radius of curvature (e.g., radius of curvature 5 cm, 1 cm, 7.5 mm, 5 mm, 4 mm, etc.) in which the bended display  110  is operable. 
       FIG. 2  is a schematic block diagram for configurations of a bended display device according to the present specification. 
     Referring to  FIG. 2 , a device  100  according to the present specification includes a bended display  110 , a tilt sensor  120 , and a control unit  130 . 
     Since the bended display  110  has already been explained with reference to  FIG. 1 , explanation on the bended display is omitted at this time. 
     The tilt sensor  120  can sense a posture of the device  100 . The posture of the device  100  shows the degree of tilting of the device  100  on the basis of gravity direction, a direction at which the device is facing on the basis of terrestrial magnetism, whether the device  100  is in a stationary state or a rotating state, or whether the device  100  is put in vertical direction or horizontal direction. 
     In order to sense the posture of the device  100 , the tilt sensor  120  can forward information to the control unit using one or more sensors mounted on the device  100 . The sensor can include a gravity sensor, a terrestrial magnetism sensor, a motion sensor, a gyro sensor, an acceleration sensor, and the like.

     The control unit  130  can control a function of the device  100 . In particular, the control unit  130  can display information on an event (hereinafter, event information), which occurs in the middle of executing an application for displaying a screen on the main region  111 , on the sub-region  112 . In particular, the control unit can display and manage the function of the device  100  using the sub-region  112 . In this case, the event information displayed on the sub-region  112  may correspond to information related to the application for displaying the screen on the main region  111  or information irrespective of the application for displaying the screen on the main region  111 . For example, the information related to the application for displaying the screen on the main region  111  may correspond to various informations such as pop-up information corresponding to the application, attachment information, status information, control information, and the like. If it is necessary to control the screen displayed on the main region  111 , it may be able to control a function for the screen by operating the sub-region  112 . On the contrary, for example, the information irrespective of the application for displaying the screen on the main region  111  may correspond to information for notifying data in response to message reception (e.g., SMS (short message service)/MMS (multimedia message service) based message reception), mail reception, information reception of a push service, notification reception of a social network service (SNS), and the like, or information for notifying status information (e.g., charging state of a battery, notification of data clipped by a user, indicator, etc.) of the device  100 .

     The control unit  130  according to the present specification can control the scroll speed of event information displayed on the sub-region  112  in a manner of associating the scroll speed with a posture of the device  100  sensed by the inclination sensor  120 . As mentioned in the foregoing description, the event information can be displayed on the sub-region  112 . In this case, if a user is interested in the information displayed on the sub-region  112 , the user may want to more closely watch the information displayed on the sub-region  112 . To this end, the user may tilt the device  100  to make the sub-region of the device  100  to be positioned at the front side of a gaze of the user. 
     In the following, control logic of the control unit  130  according to the present specification is explained in more detail with reference to  FIGS. 4 to 10 . 
       FIG. 4  is a diagram for an example of displaying information on an event, which has occurred in the middle of executing an application for displaying a screen on a main region of a bended display, on a sub-region. 
       FIG. 4  shows a situation that the control unit  130  receives a message while playing and displaying a video on the main region  111  and displays the message on the sub-region  112  as event information. 
       FIG. 5  is a diagram for an example of tilting a device to more closely watch event information displayed on a sub-region. 
     When a posture of the device is tilted in a manner that a direction to which the sub-region  112  is facing is tilted to a direction at which the main region  111  is facing, the control unit  130  according to the present specification can increase the scroll speed of the event information displayed on the sub-region  112 . If a user of the device  100  recognizes that the event information is displayed on the sub-region  112 , the user may want to more closely watch the event information displayed on the sub-region  112 . Since the sub-region  112  has a prescribed curvature, in order for the user to more closely watch the sub-region  112 , the user may tilt the device  100  to make the sub-region  112  to be positioned at the front side of a gaze of the user. In this case, the control unit  130  can sense that the posture of the device  100  is tilted via the tilt sensor  120 . As shown in  FIG. 5 , if the posture of the device  100  is tilted, it can be determined as the user intends to more closely watch the sub-region  112 . 
     Moreover, the control unit  130  can increase the scroll speed in proportion to a tilted level of the posture of the device  100 . In particular, the more the device is tilted, the more the scroll speed increases. 
     On the contrary, when the direction at which the main region  111  is facing is tilted to the direction at which the sub-region is facing, the control unit  130  can decrease the scroll speed of the event information displayed on the sub-region  112 . 
     Meanwhile, the event information displayed on the sub-region  112  may or may not be scrolled on the sub-region  112  at the time of generating the event information. Preferably, the control unit  130  according to the present specification can start to scroll the event information displayed on the sub-region  112  when the posture of the device is tilted in a manner that the direction at which the sub-region  112  is facing is tilted to the direction at which the main region  111  is facing. 
     According to the embodiment of the present specification, the control unit  130  can scroll the event information displayed on the sub-region  112  in a direction orthogonal to a direction to which the posture of the device  100  is tilted when the posture of the device is tilted in a manner that the direction at which the sub-region  112  is facing is tilted to the direction at which the main region  111  is facing. 
     According to one embodiment of the present specification, if an application for displaying a screen on the main region  111  corresponds to an application for playing a digital media, the control unit  130  can reduce a volume of the digital media from the timing at which the posture of the device sensed by the tilt sensor  120  is tilted. 
     According to a different embodiment of the present specification, if an application for displaying a screen on the main region  111  corresponds to an application for playing a digital media, the control unit  130  can stop playing the digital media from the timing at which the posture of the device sensed by the tilt sensor is tilted. 
       FIG. 6  is a diagram for an example of controlling the scroll of event information by touching a sub-region. 
     Referring to  FIG. 6 , it is able to see that a user touches the sub-region  112 . According to the embodiment of the present specification, the sensor unit  160  can be mounted on the bended display  110 . Hence, the control unit  130  can detect various user inputs inputted on the bended display  110  via the sensor unit  160 . For example, if the sensor unit  160  includes a touch sensor, the control unit  130  can receive various touch inputs of the user inputted on the bended display  110 . In particular, in the present specification, the bended display  110  of the device  100  may correspond to a touch screen. 
     In this case, the bended display  110  senses a contact of a user and can output an input signal to the control unit  130 . If the user touches the sub-region  112  while the event information displayed on the sub-region  112  is scrolled, the control unit  130  can stop scrolling the event information displayed on the sub-region  112 . By doing so, when the event information displayed on the sub-region  112  is scrolled, the user temporarily stops the scrolling and may be able to check important information in detail. 
     According to one embodiment of the present specification, if a user maintains a touch touched on the sub-region  112 , the control unit  130  can maintain the scroll of the event information displayed on the sub-region  112  in a stop state. 
     According to a different embodiment of the present specification, if the user stops scrolling the event information displayed on the sub-region  112  and then touches the sub-region  112  again, the control unit  130  can control the scroll of the event information displayed on the sub-region  112  to be started again. 
       FIG. 7  is a diagram for an example of moving content of event information by sweeping a sub-region while the sub-region is touched. 
     Referring to  FIG. 7 , a user sweeps a touch in the left direction in a state that the user maintains the touch touched on the sub-region  112 . 
     According to a further different embodiment of the present specification, when the user sweeps the touch in a direction in a state that the user maintains the touch touched on the sub-region  112 , the control unit  130  can control contents of the event information displayed on the sub-region  112  to be moved in the direction to which the touch is swept. The user can more quickly move to content preferred by the user among the contents of the event information via the sweeping. 
       FIG. 8  is a diagram for an example of restoring a posture of a device to an original position. 
     According to a different embodiment of the present specification, if the posture of the device  100  is returned to the posture at the time of generating the event information, the control unit  130  can stop displaying the event information displayed on the sub-region  112 . If a user changes the posture of the device  100  to an original position, it can be comprehended as the user has checked all of the event information displayed on the sub-region  112 . 
     Meanwhile, an application for displaying a screen on the main region  111  may correspond to an application for playing digital media. According to one embodiment of the present specification, if the posture of the device  100  is returned to the posture at the time of generating the event information, the control unit  130  can make a volume of the digital media to be returned to an original volume. According to a different embodiment of the present specification, the control unit  130  can play the digital media again. 
       FIGS. 9 and 10  are diagrams for an example that an application for displaying a screen on a main region corresponds to an application for playing digital media using real-time data received from the external. 
     In the examples mentioned earlier in  FIGS. 4 to 8 , it is assumed that an application for displaying a screen on the main region  111  plays digital media stored in the storing unit  180 . Hence, the control unit  130  can stop playing the digital media or play the digital media again. Moreover, a user does not fail to lose sound or a screen of the digital media while checking the event information displayed on the sub-region  112  via the pause of the digital media. Yet, the application for displaying a screen on the main region  111  may correspond to an application for playing digital media using real-time data received from the external. For example, the real-time data may correspond to a streaming data or DMB data provided by an external server. In this case, the user may fail to lose sound or a screen of the digital media while checking the event information displayed on the sub-region  112 . 
     According to the embodiment of the present specification, if an application for displaying a screen on the main region  111  corresponds to an application for playing digital media using real-time data received from the external, the control unit  130  can store the data of the digital media received in real-time from the timing at which a posture of the device  100  sensed by the tilt sensor  120  is tilted. In this case, the control unit  130  can store the data of the digital media received in real time in the storing unit  180 . The control unit  130  can terminate the storing of the data when the posture of the device  100  is returned to a posture at the timing of generating the event information. 
     Moreover, the control unit  130  can display information related to the stored data on the sub-region  112 . In this case, if the stored data includes images, the control unit  130  can display at least one of the stored images on the sub-region  112  as a thumbnail. Preferably, the thumbnail corresponds to a plurality of thumbnails arranged at the sub-region  112  according to the passage of time. Referring to the example shown in  FIG. 9 , it may be able to check  4  thumbnails displayed on the sub-region  112 . The  4  thumbnails correspond to thumbnails for a digital media received in real time between the timing at which the posture of the device  100  is tilted and the timing at which the posture of the device is returned to the original posture (i.e., while the user checks the event information displayed on the sub-region  112 ). The control unit  130  can generate a thumbnail image file by selecting an image of a core part from the data of the digital media received and stored in real time. The image selected from the stored digital media can be selected in various ways. 
     Subsequently, as shown in  FIG. 10 , if a user touches a thumbnail from among a plurality of thumbnails, the control unit  130  can play the digital media from a part corresponding to the touched thumbnail among the stored data. 
     In the following, a method of controlling the aforementioned bended display device  100  is explained. In explaining the control method according to the present specification, since each of the configurations of the bended display device  100  has already been explained in detail, overlapped explanation is omitted at this time. 
       FIG. 11  is a schematic flowchart for an algorithm of a control method according to one embodiment of the present specification. 
     Referring to  FIG. 11 , in the step S 200 , the control unit  130  executes an application for displaying a screen on the main region  111  of the bended display  110 . The control unit  130  controls the processor to move to the step S 210  from the step S 200 . 
     In the step S 210 , the control unit  130  determines whether or not event information is generated. If the event information is not generated (‘no’ in the step S 210 ), the control unit  130  controls the processor to move to the step S 200 . Hence, the control unit  130  repeatedly executes the steps S 200  and S 210 . On the contrary, if the event information is generated (‘yes’ in the step S 210 ), the control unit  130  controls the processor to move to the step S 220 . 
     In the step S 220 , the control unit  130  displays the event information on the sub-region  112  of the bended display  110 . The control unit  130  controls the processor to move to the step S 230  from the step S 220 . 
     In the step S 230 , the control unit  130  monitors a posture of the device  100  via a tilt sensor  120  capable of sensing the posture of the device  100 . The control unit  130  controls the processor to move to the step S 240  from the step S 230 . 
     In the step S 240 , the control unit  130  determines whether or not the posture of the device  100  is tilted. If the posture of the device  100  is not tilted (‘no’ in the step S 240 ), the control unit  130  controls the processor to move to the step S 230 . Hence, the control unit  130  repeatedly executes the steps S 230  and S 240 . On the contrary, if the posture of the device  100  is tilted (‘yes’ in the step S 240 ), the control unit  130  controls the processor to move to the step S 250 . 
     In the step  150 , the control unit  130  controls the scroll speed of the event information displayed on the sub-region  112  of the bended display  110 . 
     According to one embodiment of the present specification, in the step S 250 , if the posture of the device  100  is tilted in a manner that a direction at which the sub-region  112  is facing is tilted to a direction at which the main region  111  is facing, the control unit  130  can increase the scroll speed of the event information displayed on the sub-region  112 . In this case, the control unit  130  can increase the scroll speed in proportion to a tilted level of the posture of the device  100 . On the contrary, when the direction at which the main region  111  is facing is tilted to the direction at which the sub-region is facing, the control unit  130  can decrease the scroll speed of the event information displayed on the sub-region  112 . 
     According to a different embodiment of the present specification, in the step S 250 , if the posture of the device  100  is tilted in a manner that a direction at which the sub-region  112  is facing is tilted to a direction at which the main region  111  is facing, the control unit  130  can control the scroll of the event information displayed on the sub-region  112  to be started. 
     Meanwhile, an application for displaying a screen on the main region  111  may correspond to an application for playing digital media. In this case, the control unit  130  can reduce a volume of the digital media from the timing at which the posture of the device  100  sensed by the tilt sensor  120  is tilted. And, the control unit  130  can control the playback of the digital media to be stopped from the timing at which the posture of the device  100  sensed via the tilt sensor  120  is tilted. On the contrary, since the aforementioned embodiments are explained with explained through  FIGS. 5 and 8 , overlapped explanation is omitted at this time. 
     Meanwhile, if the posture of the device  100  is tilted in a manner that the direction at which the sub-region  112  is facing is tilted to the direction at which the main region  111  is facing, the control unit  130  can control the scroll direction of the event information displayed on the sub-region  112  to be orthogonal to the direction to which the posture of the device  100  is tilted. 
       FIG. 12  is a schematic flowchart for an algorithm of a control method according to a different embodiment of the present specification. 
     Referring to  FIG. 12 , it is able to see that contents of the steps S 200  to S 240  are identical to the contents of  FIG. 11 . Hence, the step S 251  having a difference from the embodiment shown in  FIG. 11  is explained first. 
     In the step S 251 , the control unit  130  can control the scroll speed of the event information displayed on the sub-region  112  of the bended display  110  to be increased or decreased. The control unit  130  controls the processor to move to the step S 260  from the step S 251 . 
     In the step S 260 , the control unit  130  determines whether or not the posture of the device  100  is returned to a posture at the time of generating the event information. If the posture of the device  100  is not returned (‘no’ in the step S 260 ), the control unit  130  controls the processor to move to the step S 270 . Hence, the control unit  130  repeatedly executes the steps S 251  and S 260 . On the contrary, if the posture of the device  100  is returned (‘yes’ in the step S 260 ), the control unit  130  controls the processor to move to the step S 270 . 
     In the step S 270 , the control unit  130  can stop displaying the event information displayed on the sub-region  112 . And, the control unit  130  ends the processor. 
       FIG. 13  is a schematic flowchart for an algorithm of a control method according to a further different embodiment of the present specification. 
     Referring to  FIG. 13 , it is able to see that contents of the steps S 200  to S 250  are identical to the contents of  FIG. 11 . Hence, the step S 261  having a difference from the embodiment shown in  FIG. 11  is explained first. 
     In the step S 261 , the control unit  130  determines whether or not a user touches the sub-region  112 . If the user does not touch the sub-region (‘no’ in the step S 261 ), the control unit  130  controls the processor to move to the step S 250 . Hence, the control unit  130  repeatedly executes the steps S 250  and S 261 . On the contrary, if the user touches the sub-region (‘yes’ in the step S 261 ), the control unit  130  controls the processor to move to the step S 262 . 
     In the step S 262 , the control unit  130  controls the scroll of the event information displayed on the sub-region  112  to be stopped. The control unit  130  controls the processor to move to the step S 263  from the step S 262 . 
     In the step S 263 , the control unit  130  determines whether or not the user maintains a touch touching the sub-region  112 . If the user maintains the touch (‘yes’ in the step S 261 ), the control unit  130  controls the processor to move to the step S 262 . Hence, the control unit  130  repeatedly executes the steps S 262  and S 263 . On the contrary, if the user does not maintain the touch (‘no’ in the step S 263 ), the control unit  130  controls the processor to move to the step S 264 . 
     In the step S 264 , the control unit  130  controls the scroll of the event information displayed on the sub-region  112  to be started again. And, the control unit  130  ends the processor. Since the method described in  FIG. 13  is explained in detail with reference to  FIG. 6 , overlapped explanation is omitted at this time. 
       FIG. 14  is a schematic flowchart for an algorithm of a control method according to a further different embodiment of the present specification. 
     Referring to  FIG. 14 , it is able to see that contents of the steps S 200  to S 262  and contents of the step S 264  are identical to the contents of  FIG. 13 . Hence, the step S 263 ′ having a difference from the embodiment shown in  FIG. 13  is explained first. 
     In the step S 263 ′, the control unit  130  determines whether or not a user retouches the sub-region  112 . If the user does not retouch the sub-region (‘no’ in the step S 263 ), the control unit  130  controls the processor to move to the step S 262 . Hence, the control unit  130  repeatedly executes the steps S 262  and S 263 ′. On the contrary, if the user retouches the sub-region (‘yes’ in the step S 263 ′), the control unit  130  controls the processor to move to the step S 264 . Since the step S 264  has already been explained, overlapped explanation is omitted at this time. 
       FIG. 15  is a schematic flowchart for an algorithm of a control method according to a further different embodiment of the present specification. 
     Referring to  FIG. 15 , it is able to see that contents of the steps S 200  to S 262  are identical to the contents of  FIG. 13 . Hence, the step S 265  having a difference from the embodiment shown in  FIG. 13  is explained first. 
     In the step S 265 , the control unit  130  determines whether or not a user sweeps a touch in a direction while If the user does not sweep the touch (‘no’ in the step S 265 ), the control unit  130  controls the processor to move to the step S 262 . Hence, the control unit  130  repeatedly executes the steps S 262  and S 265 . On the contrary, if the user sweeps the touch (‘yes’ in the step S 265 ), the control unit  130  controls the processor to move to the step S 266 . 
     In the step S 264 , the control unit  130  controls contents of the event information displayed on the sub-region  112  to move to the direction in which the touch is swept. And, the control unit  130  ends the processor. 
       FIG. 16  is a schematic flowchart for an algorithm of a control method according to a further different embodiment of the present specification. 
     Referring to  FIG. 16 , it is able to see that contents of the steps S 200  to S 250  are identical to the contents of  FIG. 11 . Hence, the step S 280  having a difference from the embodiment shown in  FIG. 11  is explained first. 
     In the step S 280 , if an application for displaying a screen on the main region  111  corresponds to an application for playing digital media using a real-time data received from the external, the control unit  130  stores the data of the digital media received in real time from the timing at which a posture of the device sensed via the tilt sensor  120  is tilted. The control unit  130  controls the processor to move to the step S 281  from the step S 268 . 
     In the step S 281 , the control unit  130  determines whether or not the posture of the device  100  is returned to the posture at the time of generating the event information. If the posture of the device is not returned (‘no’ in the step S 281 ), the control unit  130  controls the processor to move to the step S 280 . Hence, the control unit  130  repeatedly executes the steps S 280  and S 281 . On the contrary, if the posture of the device is returned (‘yes’ in the step S 281 ), the control unit  130  controls the processor to move to the step S 282 . 
     In the step S 282 , the control unit  130  terminates the storing of the data. And, the control unit  130  controls the processor to move to the step S 283  from the step S 282 . 
     In the step S 283 , the control unit  130  displays information related to the stored data on the sub-region. According to the embodiment of the present specification, if the stored data includes images, at least one of the stored images can be displayed on the sub-region as a thumbnail. The thumbnail may correspond to a plurality of thumbnails arranged at the sub-region  112  according to the passage of time. The control unit  130  controls the processor to move to the step S 284  from the step S 283 . 
     In the step S 284 , the control unit  130  plays the digital media from a part corresponding to touched information among the stored data. And, the control unit  130  ends the processor.
