And, the second body includes a second display unit and may display an image on the second area using the second display unit. And, the third body includes a third display unit and may display an image on the third area using the third display unit. In particular, a display unit is separately included in each body and may display an image on an area included in each body. And, as an example, the display unit 110 may display images on the first area, the second area and the third area, respectively, as an integrated unit. As an example, if the portable device 100 corresponds to a flexible display device, the display unit 110 may correspond to an integrated structure. In this case, the display unit 100 may display images on the first area, the second area and the third area, respectively, based on folding of the flexible display device. In particular, the display unit 110 may correspond to a unit capable of displaying images on the first area of the first body, the second area of the second body and the third area of the third body, by which the present specification may be non-limited.
And, as an example, the display unit 110 may display images on a front side area and a rear side area of the first body, the second body and the third body. More specifically, the aforementioned first area may be set to a front side or a rear side of the first body.

The portable device 100 may include a first sensor unit 120. In this case, as an example, the first sensor unit 120 may correspond to a sensor unit configured to detect a folded state of the second body and a folded state of the third body. More specifically, the first sensor unit 120 may correspond to a sensor unit configured to detect whether the second body and the third body are folded to the first body. In this case, the first sensor unit 120 may detect a first folding angle between the first body and the second body. And, the first sensor unit 120 may detect a second folding angle between the first body and the third body. In this case, as an example, the first sensor unit 120 measures an angle formed by an internal angle between the first body and the second body or an angle formed by an internal angle between the first body and the third body and may be then able to sense whether the portable device is in an unfolded state or a folded state. As a different embodiment, the first sensor unit 120 may sense whether each of the bodies is folded based on a distance of each body or an operation state of a hinge. And, the first sensor unit 120 may deliver detected folding information to the processor 150. In particular, the first sensor unit 120 may correspond to a sensor unit capable of detecting a folded state of the first body and the second body and a folded state of the first body and the third body, by which the present specification may be non-limited.
A second sensor unit 130 may correspond to a sensor configured to detect a state that a rear side of each body is contacted with a different real object. In this case, the real object may correspond to a hand of a user, a desk or the like. In particular, the second sensor unit may correspond to a sensor unit configured to detect whether a rear side of each body is in a state of being contacted with a different real object. In this case, as an example, the second sensor unit 130 may detect a state of being contacted with a different real object using a resistive touch sensor or a capacitive touch sensor. As a different example, the second sensor unit 130 may include at least one selected from the group consisting of an infrared sensor, a proximity sensor, an ultrasonic sensor and an illumination sensor. In this case, the second sensor unit 130 may correspond to a sensor configured to measure distance and may be able to detect whether a rear side of each body is in a state of being contacted with a different real object based on distance between the real side of each body and the different real object. In particular, the second sensor unit 130 may correspond to a sensor unit configured to detect whether a real side of each body is in a state of being contacted with a different real object, by which the present specification may be non-limited.
The portable device 100 may further include a control input sensing unit 140 as an optional configuration. In this case, the control input sensing unit 140 may deliver environment recognized by a user input or a device to the processor 150 using at least one or more sensors installed in the portable device 100. More specifically, the control input sensing unit 140 may sense a control input of a user using at least one or more sensors installed in the display device 100. In this case, at least one or more sensing means may include various sensing means such as a touch sensor, a fingerprint sensor, a motion sensor, a proximity sensor, an illumination sensor, a voice recognition sensor, a pressure sensor and the like configured to sense a control input. The control input sensing unit 120 is a common name of the aforementioned various sensing means. The aforementioned sensors may be included in a device as a separate element or may be included in the device in a manner of being integrated into at least one or more elements. In particular, the control input sensing unit 120 may correspond to a unit configured to sense a control input of a user, by which the present specification may be non-limited. And, as an example, the control input may correspond to a gesture input and may correspond to contact or non-contact various inputs. And, the control input may correspond to an input inputted by an input device or an input inputted by voice or audio, by which the present specification may be non-limited. And, as an example, the control input sensing unit 130 may correspond to an element integrated with a display unit 110. As an example, the display unit 110 may correspond to a touch sensitive display unit 110.
The processor 150 may correspond to a unit configured to control at least one selected from the group consisting of the display unit 110, the first sensor unit 120, the second sensor unit 130 and the control input sensing unit 140. More specifically, the processor 150 may detect a folded state of the first body and the second body and a folded state of the first body and the third body using the first sensor unit 120. In this case, as an example, the processor 150 may detect a first folding angle corresponding to an internal angle between the first body and the second body using the first sensor unit 120. And, the processor 150 may detect a second folding angle corresponding to an internal angle between the first body and the third body. In this case, as an example, the processor 150 may set a first mode based on the first folding angle and the second folding angle. In this case, as an example, the processor 150 may execute a first application in the first mode. The first mode may correspond to a state that the first folding angle and the second folding angle are less than a first threshold angle. In this case, the first threshold angle may correspond to a threshold angle determining whether a device is folded and may have a prescribed error range. The first threshold angle is a very small angle and may correspond to an angle configured to detect a folded state. In particular, the first mode may correspond to a mode configured to be set in a state that both the second body and the third body are folded to the first body. As a different embodiment, the first mode may correspond to a state that the first folding angle and the second folding angle are equal to or greater than a second threshold angle. In this case, the second threshold angle may correspond to a threshold angle determining whether a device is unfolded and may have a prescribed error range. In particular, the second threshold angle is a very large angle close to 180 degrees and may correspond to an angle configured to detect an unfolded state. In particular, the first mode may correspond to a mode configured to be set in a state that both the second body and the third body are unfolded. In this case, the processor 150 may detect change of the first folding angle and change of the second folding angle using the first sensor unit 120. And, the processor 150 may detect whether a rear side of each body is in a state of being contacted with a different real object using the second sensor unit 130. In this case, as an example, if the processor 150 detects that the changed first folding angle is equal to or greater than a third threshold angle, the change second folding angle is less than a fourth threshold angle and a rear side of the second body is in a state of being contacted with a different real object, the processor may switch the first mode to a second mode. In this case, the second mode may correspond to a mode displaying a first application on a first area using the display unit 110. And, the second mode may correspond to a mode displaying a second application associated with a first object included in the first application on a second area. Regarding this, it shall be described later with reference to FIG. 3.
The aforementioned elements may be included in the portable device 100 as a separate element or may be included in the portable device in a manner of being integrated into at least one or more elements.
FIG. 2 is a diagram for a method of folding a portable device according to one embodiment of the present specification. As mentioned in the foregoing description, a portable device 100 may include a first body 210, a second body 220 and a third body 230. In this case, the second body 220 may be located at the left of the first body 210. And, the third body 230 may be located at the right of the first body 210.
The portable device 100 may make the first area, the second area and the third area of the display unit 110 to be located at a front side direction of the portable device. In particular, the front direction may correspond to a direction in which an image is displayed in the portable device 100. And, a rear side direction may correspond to a direction in which an image is not displayed in the portable device 100. In particular, in case that a user holds the portable device 100, the front side direction corresponds to a direction facing the user and the rear side direction may correspond to an opposite direction of the front side direction. In this case, as an example, the second body 220 may be folded to the first body 210 to make a front side of the second body 220 and a front side of the first body to be overlapped with each other. And, the third body 230 may be folded to the first body 210 to make a rear side of the third body 230 and a rear side of the first body 210 to be overlapped with each other. In particular, the second body 220 and the third body 230 may be folded to make two sides of the first body 210 to be contacted with the second body 220 and the third body 230, respectively.
As a different example, the second body 220 may be folded to the first body 210 to make a rear side of the second body 220 and the rear side of the first body to be overlapped with each other. And, the third body 230 may be folded to the first body 210 to make a front side of the third body 230 and the front side of the first body 210 to be overlapped with each other. In particular, the second body 220 and the third body 230 may be folded to make two sides of the first body 210 to be contacted with the second body 220 and the third body 230, respectively.
In particular, the portable device 100 including 3 bodies may have various folding structures, by which the present specification may be non-limited.
FIG. 3 is a diagram of a method for a portable device to set an operation mode based on a folding angle according to one embodiment of the present specification. In this case, as an example, if both a second body 220 and a third body 230 are in an unfolded state, a portable device 100 may set a first mode. And, as an example, if the both the second body 220 and the third body 230 are in a folded state, the portable device 100 may set the first mode. This is identical to what is mentioned earlier in FIG. 1.
The portable device 100 may detect change of a first folding angle 310 and change of a second folding angle 320 in the first mode. In this case, the portable device 100 may detect a state that the changed first folding angle 310 is equal to or greater than a first threshold angle and the changed second folding angle 320 is less than a second threshold angle. In this case, as an example, the first threshold angle may correspond to an angle between 90 degrees and 180 degrees. And, the second threshold angle may correspond to an angle between 0 degree and 90 degrees. In particular, the first threshold angle and the second threshold angle may correspond to a threshold angle configured to determine a folded state of the first body 210, that of the second body 220 and that of the third body 230. In this case, the portable device 100 may detect a state that the rear side of the second body 220 is contacted with a different real object. In this case, the different real object may correspond to a user, a desk or the like. If the first folding angle 310 is equal to or greater than the first threshold angle, the second folding angle 320 is less than the second threshold angle and the rear side of the second body 220 is in the state of being contacted with the different real object, the portable device 100 may switch the first mode to a second mode. More specifically, referring to FIG. 3, the portable device 100 detects a folded state of the portable device, which is used in a manner of being put on a desk or the like in a prescribed form, and may set the second mode. In this case, as an example, the second mode corresponds to a cradle mode. The cradle mode may correspond to a mode of using the portable device 100 in a manner of putting the portable device on a prescribed location. By doing so, a user may use the portable device 100 including 3 bodies as a notebook or a device of a form of being cradled.
As a further different example, the portable device 100 may set the second mode only when the portable device further detects that a landscape mode is set. More specifically, the portable device may be set by either a portrait mode or the landscape mode. In this case, the portrait mode may correspond to a mode of the portable device of which the portable device 100 is used vertically. And, the landscape mode may correspond to a mode of the portable device of which the portable device 100 is used horizontally. As an example, the portable device 100 detects a direction of the portable device 100 using a sensor unit (not depicted) and may be able to set either the portrait mode or the landscape mode based on the detected direction. In this case, the portable device 100 may be configured to switch to the second mode in the landscape mode only. By doing so, a user may control a method of setting the second mode.
And, as an example, if the first mode is set in a manner that both the second body 220 and the third body 230 are unfolded, the portable device 100 may display a first application on a first area of the first body, a second area of the second body 220 and a third area of the third body 230. In particular, the portable device 100 may display the first application on a whole body. In this case, if the first mode is switched to the second mode, the portable device 100 may display the first application on the first area in a manner of reducing the first application with a predetermined ratio. In particular, the portable device 100 may display the first application on the first area in a manner of reducing the first application in accordance with a size of the first area.
And, as an example, if the first mode is set in a manner that both the second body 220 and the third body 230 are folded, the portable device 100 may display the first application on the second area of the second body 220 or the third area of the third body 230. In this case, if the first mode is switched to the second mode, the portable device 100 may display the first application in a manner of moving the first application to the first area. In particular, the portable device 100 may display the first application on the first area in a same size in a manner of moving the first application to the first area.
FIGS. 4A and 4B are diagrams of a method for a portable device to display a second application for an object included in a first application in a second mode according to one embodiment of the present specification. A portable device 100 may execute a first application 410 in a first mode. In this case, as an example, the first application 410 may correspond to an internet application. In this case, the portable device may detect that the first mode is switched to a second mode. If the first mode is switched to the second mode, the portable device 100 may display the first application 410, which is used to be executed in the first mode, on a first area of a first body 210. And, the portable device 100 may display a second application 420 associated with the first application 410 on a second area of a second body 220. In this case, as an example, the second application 420 may correspond to an application related to a first object 430 included in the first application 410. In this case, the first object 430 may correspond to an image, a text, an icon and the like included in the first application 410. And, the first object 430 may correspond to an area configured by a user or a processor 150.
As an example, referring to FIG. 4A, the first application 410 may correspond to an internet application. And, the first object 430 may correspond to a search window 430 included in the internet application. In this case, the second application 420 may correspond to a virtual keyboard application as an application related to the search window 430. In particular, if a user switches the first mode to the second mode, the portable device 100 may display a keyboard application 420 related to the search window 430 of the internet application 410 on the second area.
As a different example, referring to FIG. 4B, the first application 410 may include a second object 450. In this case, as an example, the second object 450 may correspond to an image. In this case, if the first mode is switched to the second mode, the portable device 100 may display a third application 440 related to the second object 450 on the second area. In this case, the third application 440 may correspond to an application used for determining whether to store an image. In particular, the portable device 100 may display an application related to a specific object among objects included in the first application 410 on the second area.
In this case, as an example, the portable device 100 may display the first application 410 in the first mode. In this case, the portable device 100 may detect a first control input selecting a first object 430 included in the first application 410 in the first mode. Subsequently, if the first mode is switched to the second mode, the portable device 100 may display a second application 420 related to the first object on the second area.
And, the portable device 100 may detect a second control input selecting a second object 450 in the first mode. Subsequently, if the first mode is switched to the second mode, the portable device 100 may display a third application 440 related to the second object 450 on the second area. In particular, the portable device 100 may display an application related to a selected object.
As a different example, in case that the portable device 100 displays the second application 420 on the second area in the second mode, the portable device 100 may detect a third control input selecting the second object 450. In this case, the portable device 100 may display the third application 440 on the second area based on the third control input. In particular, the portable device 100 may change an application displayed on the second area based on a control input in the second mode.
FIGS. 5A and 5B are diagrams of a method for a portable device to control an application based on a control input in a second mode according to one embodiment of the present specification.
