According to another exemplary embodiment of the present specification, when an execution image of a specific icon is displayed on the first display unit 310 and 410, and when the user unfolds the foldable mobile device after a zoom-in operation is performed, an image being in connection with the first image is displayed on the second display unit 320 and 420 as the second image. Herein, the second image corresponds to an image having the same zoom-in ratio as the first image or corresponds to an image having a zoom-in ratio greater than that of the first image.
(a) and (b) of FIG. 5 respectively show examples of an image, which is in connection with a first image, being displayed on a second display unit 120 as a second image, when a foldable mobile device is unfolded without any zoom-in operations after an execution image of a specific icon is displayed on a first display unit 110 of the foldable mobile device shown in FIG. 1. More specifically, (a) and (b) of FIG. 5 respectively show exemplary embodiments of the present specification of a case when the second image of a predetermined display mode corresponds to an image being in connection with the first image.
Most particularly, (a) of FIG. 5 shows an example of a first image being displayed on the touchscreen of the first display unit 110, when a location tracking application for searching my current position (or the current position of the user) or someone else's current position (or the current position of another user) is being executed from the first display unit 110 of the foldable mobile device shown in FIG. 1. For example, when my current position as been requested, the Current Position (or ‘You are here’) being indicated on the map becomes my current position (or the current position of the current user). In another example, when someone else's current position has been requested, the Current Position (or ‘You are here’) being indicated on the map becomes the current position of the particular person requested by me (i.e., the current user). Additionally, the Current Position (or ‘You are here’) marked (or indicated) on the map may be used (or considered) as an important point having a significance given by the current user. (b) of FIG. 5 shows an example of an image being in connection with the first image being displayed on a combined (or merged) touchscreen of the first and second folding areas 130 and 140 of the second display unit 120 as the second image, when the user unfolds the foldable mobile device without performing any zoom-in operations, while the foldable mobile device is in a state of having the current position of an individual (or person) designated by the user being indicated (or marked) on a map, which is displayed on the touchscreen of the first display unit 110 of the foldable mobile device, as shown in (a) of FIG. 1.
For example, the second image of (b) of FIG. 5 includes a first image, which is displayed on the first display unit 110 of (a) of FIG. 5, and a third image, which is not displayed on the first display unit 110. This is because the size of the touchscreen of the first display unit 110 is smaller than the size of a combined (or merged) touchscreen consisting of the touchscreens of the first and second folding areas 130 and 140 of the second display unit 120 put together. At this point, according to the exemplary embodiment of the present specification, an object of the second image being displayed on the second display unit 120 is larger or identical to an object of the first image being displayed on the first display unit 110. At this point, according to the exemplary embodiment of the present specification, since the current position corresponds to an important point designated by the user, when the foldable mobile device is unfolded, the current position must be displayed on the second display unit 120.
Meanwhile, according to the exemplary embodiment of the present specification, although it is not displayed on the first display unit 110, when Point of Interest (POI) information, which is predetermined by the user, exists in the surroundings of the current position, which is marked on the map, a third image including the POI information is displayed on the second display unit 120. According to the exemplary embodiment of the present specification, the POI information is displayed as an icon, which easily indicates the type of the point of interest (POI). Although the POI information may be designated by the user, the map producer (or provider) may also designate public facilities or hospitals, and so on, as the POI information. In the description of the present specification, examples of the user designating the POI information will be described, and POI information designated by the map producer (or provider) may also be displayed herein.
In (b) of FIG. 5, two different types of POI information 151 and 152 are displayed on the second folding area 140 of the second display unit 120. (b) of FIG. 5 shows an example of the two different types of POI information 151 and 152 being located on the right side of the current position. If at least one type of POI information is located on the left side of the current position, the section displaying the current position may be shifted rightward and displayed in the second display unit 120 as compared to the displayed location shown in (b) of FIG. 5.
If there is no POI information designated by the user in the surroundings of the current position, the same image as that of (a) of FIG. 5 is displayed on the touchscreen of the first folding area 130 of the second display unit 120, and a third image, which was not displayed on the first display unit 110 shown in (a) of FIG. 5, may be displayed on the touchscreen of the second folding area 140.
In another example, a first image is displayed at the center (or in the middle) of the combined touchscreen of the first and second folding areas 130 and 140 of the second display unit 120, and a third image may be displayed on the surroundings of the displayed first image. If a horizontal/vertical ratio of the first image is predecided, the first image may be displayed only on a partial section (e.g., center) of the display screen of the second display unit 120 as the second image. (a) and (b) of FIG. 6 respectively show examples of icons of a Home screen or Menu screen being displayed on a second display unit 120 as a second image, when a foldable mobile device is unfolded without any zoom-in operations after an execution image of a specific icon is displayed on a first display unit 110 of the foldable mobile device shown in FIG. 1. More specifically, (a) and (b) of FIG. 6 respectively show exemplary embodiments of the present specification of a case when the second image of a predetermined display mode corresponds to an icon image being in connection with the first image.
Since the content being displayed on the first display unit 110 of (a) of FIG. 6 is identical to that of (a) of FIG. 5, detailed description of the same will be omitted for simplicity.
(b) of FIG. 6 shows an example of icons of the Menu screen being displayed on each touchscreen of the first and second folding areas 130 and 140 of the second display unit 120 as the second image, when the user unfolds the foldable mobile device without performing any zoom-in operations, while the foldable mobile device is in a state of having the current position of an individual (or person) designated by the user being indicated (or marked) on a map, which is displayed on the touchscreen of the first display unit 110 of the foldable mobile device, as shown in (a) of FIG. 1.
In another example, icons of the same Home screen as the first display unit 110 are displayed on the touchscreen of the first folding area 130 of the second display unit 120, and icons of another page of the Home screen are displayed on the second folding area 140 of the second display unit 120. In yet another example, icons of the same Home screen as the first display unit 110 may be displayed on the touchscreen of the first folding area 130 of the second display unit 120, and icons of the Menu screen may be displayed on the second folding area 140 of the second display unit 120. In yet another example, icons of remaining pages of the Home screen, which is displayed on the first display unit 110, may be displayed on at least one of the first folding area 130 and the second folding area 140 of the second display unit 120.
(a) to (c) of FIG. 7 respectively show examples of a first image and a second image, when the first image is zoomed-in in the first display unit 110, and when the foldable mobile device is unfolded afterwards.
More specifically, (a) of FIG. 7 shows an example of a first image being displayed on the touchscreen of the first display unit 110, when a location tracking application for searching my current position (or the current position of the user) or someone else's current position (or the current position of another user) is being executed from the first display unit 110 of the foldable mobile device shown in FIG. 1.
When a zoom-in command is inputted in order to enlarge the first image of the first display unit 110 shown in (a) of FIG. 7, the image that is zoomed-in (or enlarged) in accordance with the zooming ratio is displayed on the first display unit 110 as shown in (b) of FIG. 7. At this point, as the first image is enlarged in accordance with the zoom-in ratio and displayed on the first display unit 110, a portion of the first image disappears from the touchscreen of the first display unit 110. This is because the objects included in the first image are also enlarged in accordance with the zoom-in ratio. At this point, the image (or portion of the image), which has disappeared from the first display unit 110 due to the zoom-in operation, may correspond to an image of the important point, to which the user has given significance prior to the zoom-in operation. For example, due to the zoom-in operation, a section of the image indicating the Current Position may not be displayed on the first display unit 110. This may occur when the zoom-in command is inputted from a specific section (or location) that is spaced apart from the section indicating the Current Position at a predetermined distance.
Herein, a zoom-in/zoom-out command may be inputted by the user by directly or indirectly touching the touchscreen using at least one finger, or by directly or indirectly touching the touchscreen using a touch pen, or by using a Menu, and so on. In another example, the zoom-in/zoom-out command may be inputted by the user using a keypad, a dome switch, a jog wheel, a jog switch, and so on, which are provided on the foldable mobile device. In yet another example, a scroll bar for inputting a zoom-in/zoom-out command may be displayed on a predetermined section of the touchscreen having the image displayed thereon. Thereafter, the zoom-in/zoom-out command may be inputted by manipulating (or operating) the scroll bar. According to the exemplary embodiment of the present specification, in the description of the present specification, if the user spreads out two fingers (i.e., drags outward) at a specific section of the touchscreen he (or she) wishes to enlarge, this gesture is recognized as a zoom-in command, and if the user gathers the two fingers inward (i.e., drags inward), this gesture is recognized as a zoom-out command. Hereinafter, in the description of the present specification, the zoom-in/zoom-out command will also be referred to as a zoom-in/zoom-out gesture for simplicity.
Additionally, when the image that is zoomed-in (or enlarged) in accordance with the zoom-in ratio, is displayed on the first display unit 110 as shown in (b) of FIG. 7, the zoom-in ratio may be set up in advance or may be decided in accordance with the spreading range of the user's two fingers. Similarly, the zoom-out ratio may also be set up in advance or may be decided in accordance with the gathering range of the user's two fingers.
When the user unfolds the foldable mobile device, while the foldable mobile device is in a state of having the first image zoomed-in by a zoom-in ratio and displayed on the first display unit 110 of the foldable mobile device, as shown in (b) of FIG. 7, a second image is displayed on the second display unit 120, as shown in (c) of FIG. 7. At this point, the second image being displayed on the second display unit 120 may correspond to the image being zoomed-in by the respective zoom-in ratio in the first display unit 110, or the second image may correspond to a zoomed-in image of the first image (i.e., the original first image) shown in (a) of FIG. 7 by the respective zoom-in ratio, when the foldable mobile device is unfolded.
In the description of the present specification, the zoom-in ratio of the image being zoomed-in and displayed on the first display unit 110 will hereinafter be referred to as a first zoom-in ratio, and the zoom-in ratio of the image being zoomed-in and displayed on the second display unit 120 will hereinafter be referred to as a second zoom-in ratio.
Hereinafter, according to the exemplary embodiment of the present specification, in the description of the present specification, when the user unfolds the foldable mobile device, while the foldable mobile device is in a state of having the first image zoomed-in by the first zoom-in ratio and displayed on the first display unit 110, the image shown in (a) of FIG. 7 (i.e., the image prior to being zoomed-in by the first zoom-in ratio) is zoomed-in by the second zoom-in ratio and displayed on the second display unit 120. According to another exemplary embodiment of the present specification, if the first zoom-in ratio is identical to the second zoom-in ratio, the first image being zoomed-in by the first zoom-in ratio may be displayed on the second display unit 120. According to yet another exemplary embodiment of the present specification, if the second zoom-in ratio is greater than the first zoom-in ratio, the first image that has been zoomed-in by the first zoom-in ratio may be further zoomed-in by a zoom-in ratio corresponding to a difference between the first zoom-in ratio and the second zoom-in ratio, thereby displaying the newly zoomed-in image on the second display unit 120.
If the first zoom-in ratio is equal to the second zoom-in ratio, the size of the objects of the image being zoomed-in and displayed on the first display unit 110, as shown in (b) of FIG. 7, is the same as the size of the objects of the image being zoomed-in and displayed on the second display unit 120, as shown in (c) of FIG. 7. Conversely, if the first zoom-in ratio is different from the second zoom-in ratio, the size of the objects of the image being zoomed-in and displayed on the first display unit 110, as shown in (b) of FIG. 7, is also different from the size of the objects of the image being zoomed-in and displayed on the second display unit 120, as shown in (c) of FIG. 7.
According to the exemplary embodiment of the present specification, the second image being displayed on the second display unit 120, as shown in (c) of FIG. 7, includes at least a portion of the image being zoomed-in and displayed on the first display unit 110. At this point, since the combined touchscreen of the second display unit 120 is larger than the touchscreen of the first display unit 110, a portion of the first image or the whole first image, which has disappeared from the first display unit 110 due to the zoom-in operation, may be additionally displayed on the second display unit 120. Additionally, the second image may further include a third image, which has not been displayed on the first display unit 110 shown in (a) of FIG. 7.
For example, as shown in (c) of FIG. 7, the zoomed-in image shown in (b) of FIG. 7 is directly displayed on the touchscreen of the first folding area 130 of the second display unit 120 without any modification, and a portion of the first image that has disappeared from the first display unit 110 due to the zoom-in operation and/or a third image that has not been displayed on the first display unit 110 prior to the zoom-in operation may be zoomed-in and then displayed.
In another example, the zoomed-in image shown in (b) of FIG. 7 may be displayed at the center of the combined touchscreen of the first and second folding areas 130 and 140 of the second display unit 120, and the portion of the first image that has disappeared from the first display unit 110 due to the zoom-in operation and/or the third image that has not been displayed on the first display unit 110 prior to the zoom-in operation may be zoomed-in and then displayed on the remaining sections of the combined touchscreen.
According to the exemplary embodiment of the present specification, in the present specification, the second zoom-in ratio is set up (or determined) based upon the first zoom-in ratio. According to the exemplary embodiment of the present specification, the first zoom-in ratio may be set up to be equal to the second zoom-in ratio. According to another exemplary embodiment of the present specification, the second zoom-in ratio may be set up to be greater than the first zoom-in ratio. According to yet another exemplary embodiment of the present specification, an image type, and at least one of a display mode of the first display unit 110 and a display mode of the second display unit 120 may be additionally used for deciding the second zoom-in ratio. At this point, also, the second zoom-in ratio is set up to be equal to or greater than the first zoom-in ratio.
Herein, the image type may be categorized as a picture (or photo), a drawing, a map, a document, a webpage, and so on. The document may correspond to a PowerPoint file. And, the display mode indicates whether each of the first image or the second image is respectively being displayed on the first and second display unit 110 and 120 in a horizontal display mode (or landscape view mode) or a vertical display mode (or a portrait view mode). In the first display unit 110, the vertical display mode (or portrait view mode) corresponds to a state when the first image is being vertically displayed, and the horizontal display mode (or landscape view mode) corresponds to the opposite state (i.e., a state when the first image is being horizontally displayed). In the second display unit 120, the vertical display mode corresponds to a case when the second image is being horizontally displayed, while the first folding area 130 of the second display unit 120 is located on the left side, and while the second folding area 140 of the second display unit 120 is located on the right side. And, in the second display unit 120, the horizontal display mode corresponds to a case when the second image is being vertically displayed, while the first folding area 130 is horizontally located on an upper portion, and while the second folding area 140 is horizontally located on a lower portion.
Thereafter, when the foldable mobile device is unfolded, while the foldable mobile device is in a state of having the first image being displayed in the first display unit 110 in the portrait view mode, the second image is also displayed in the portrait view mode in the second display unit 120. Conversely, when the foldable mobile device is unfolded, while the foldable mobile device is in a state of having the first image being displayed in the first display unit 110 in the landscape view mode, the second image is also displayed in the landscape view mode in the second display unit 120.
For example, when the user unfolds the foldable mobile device, after a drawing or picture having a pre-decided horizontal/vertical ratio is zoomed-in by the first zoom-in ratio and is displayed in the first display unit 110 in the portrait view mode, the drawing or picture that is zoomed-in by the second zoom-in ratio is displayed in the second display mode 120 in the portrait view mode. At this point, the corresponding drawing or picture may be displayed on only a portion (e.g., center) of the touchscreen of the second display unit 120 in accordance with the second zoom-in ratio. If the second zoom-in ratio is set up to be greater than the first zoom-in ratio, a portion of the picture or drawing that is zoomed-in by the first zoom-in ratio disappears from the touchscreen of the second display unit 120. Therefore, it will be preferable that the second zoom-in ratio in this case is set up to be equal to the first zoom-in ratio.
Meanwhile, when a drawing or picture being zoomed-in by a second zoom-in ratio, which is equal to the first zoom-in ratio or greater than the first zoom-in ratio, is rotated by 90 degrees (90°) and is displayed on the touchscreen of the second display mode 120 in the landscape view mode, the picture or drawing that is zoomed-in by the second zoom-in ratio may be displayed on the entire display section (or display area) of the touchscreen of the second display unit 120. Therefore, in this case, it is preferable that the second zoom-in ratio is set up to be equal to or greater than the first zoom-in ratio. Additionally, in this case, a portion of the drawing or picture that is zoomed-in by the first zoom-in ratio does not disappear from the touchscreen of the second display unit 120.
The above-described exemplary embodiment of the present specification described a case when the drawing or picture is displayed on the first display unit 110 in the portrait view mode, and the above-described exemplary embodiment of the present specification is also similarly applied to a case when the picture or drawing is displayed on the first display unit 110 in the landscape view mode. More specifically, when the foldable mobile device is unfolded, it will be more effective to zoom-in the picture or drawing that is displayed on the first display unit 110 in the landscape view mode by a second zoom-in ratio, which is equal to or greater than the first zoom-in ratio, and to rotate the zoomed-in picture or drawing by 90 degrees and to display the rotated picture or drawing on the second display unit 120 in the portrait view mode, than to display the corresponding picture or drawing on the second display unit 120 in the landscape view mode.
At this point, the shifting of the landscape view mode/portrait view mode in the second display unit 120 may be manually set up by the user or may be automatically shifted by the system by using a first zoom-in ratio, a second zoom-in ratio, a display mode of the first display unit 110, an image type, and so on.
Meanwhile, in case of a webpage or a document, just as a picture or drawing, it will be more effective to shift the display mode in the second display mode 120 and to display the corresponding webpage or document, when the foldable mobile device is unfolded. Since the horizontal/vertical ratio of the map is not pre-decided, when a zoomed-in map being displayed on the first display unit 110 in the portrait view mode is displayed on the second display unit 120 in the portrait view mode, the corresponding map is displayed on the entire display section of the touchscreen of the second display unit 120. Similarly, when a zoomed-in map being displayed on the first display unit 110 in the landscape view mode is displayed on the second display unit 120 in the landscape view mode, the corresponding map is displayed on the entire display section of the touchscreen of the second display unit 120. Therefore, in case of a map, it will be preferable to set up the first zoom-in ratio to be equal to the second zoom-in ratio.
As described above, the second zoom-in ratio may be set up to be equal to the first zoom-in ratio, or the second zoom-in ratio may be set up based upon the first zoom-in ratio, an image type, and a display mode of the first and second display units 110 and 120. In this case, the second zoom-in ratio should be greater than the first zoom-in ratio.
(a) to (d) of FIG. 8 respectively show examples of a first image and a second image, when the foldable mobile device is unfolded after the first image, which is displayed on the first display unit 110 of the foldable mobile device in the landscape view mode, is zoomed-in.
Since reference may be made to the description given in FIG. 7 on the method of inputting a zoom-in/zoom-out command and setting up first and second zoom-in ratios, detailed description of the same will be omitted in FIG. 8 for simplicity.
(a) of FIG. 8 shows an example of a first image being displayed on the touchscreen of the first display unit 110 in the landscape view mode (or horizontal display mode), when a location tracking application for searching my current position (or the current position of the user) or someone else's current position (or the current position of another user) is being executed from the first display unit 110 of the foldable mobile device shown in FIG. 1.
When a zoom-in command is inputted to the first display unit 110 of (a) of FIG. 8 in order to enlarge the first image, an image that is zoomed-in (or enlarged) in accordance with the first zoom-in ratio is displayed on the first display unit 110 in the landscape view mode (or horizontal display mode), as shown in (b) of FIG. 8. At this point, as the first image is enlarged in accordance with the first zoom-in ratio and displayed on the first display unit 110, a portion of the first image disappears from the touchscreen of the first display unit 110. This is because the objects included in the first image are also enlarged in accordance with the first zoom-in ratio.
(c) of FIG. 8 shows an example of a second image, which is zoomed-in by a second zoom-in ratio and displayed on the second display unit 120 in the portrait view mode (or vertical display mode), when the user unfolds the foldable mobile device, while the foldable mobile device is in a state of having the image, which is zoomed-in as shown in (b) of FIG. 8, being displayed on the first display unit 110 in the landscape view mode. More specifically, the second image is displayed as a single image on a combined (or merged) touchscreen, which consists of a first folding area 130 located on the left side of the second display unit 120 and a second folding area 140 located on the right side of the second display unit 120.
(d) of FIG. 8 shows an example of a second image, which is zoomed-in by a second zoom-in ratio and displayed on the second display unit 120 in the landscape view mode (or horizontal display mode), when the user unfolds the foldable mobile device, while the foldable mobile device is in a state of having the image, which is zoomed-in as shown in (b) of FIG. 8, being displayed on the first display unit 110 in the landscape view mode. More specifically, the second image is displayed as a single image on a combined (or merged) touchscreen, which consists of a first folding area 130 located on the upper portion of the second display unit 120 and a second folding area 140 located on the lower portion of the second display unit 120.
According to the exemplary embodiment of the present specification, in (c) of FIG. 8 and (d) of FIG. 8, the size of the objects included in the second image are identical to the size of the objects included in the image, which is enlarged in the first display unit 110 in accordance with the first zoom-in ratio. At this point, since the combined touchscreen of the second display unit 120 is larger than the touchscreen of the first display unit 110, a portion of the first image or the entire first image that disappears from the touchscreen of the first display unit 110 due to the zoom-in command may be zoomed-in and displayed on the second display unit 120. Additionally, in accordance with the zoom-in/zoom-out position within the touchscreen, the second display unit 120 may zoom-in a third image, which has not been displayed on the first display unit 110 shown in (a) of FIG. 8, and may additionally display the zoomed-in third image. However, depending upon whether the display mode of the second display unit 120 corresponds to the landscape view mode (or horizontal display mode) or the portrait view mode (or vertical display mode), the contents of the image that has disappeared from the touchscreen of the first display unit 110 due to the zoom-in operation and/or the contents of the third image that has not been displayed on the first display unit 110 shown in (a) of FIG. 8 may be varied (or changed).
(a) of FIG. 9 shows an example of a first image being displayed on the touchscreen of the first display unit 110, when an application, such as a pathfinder, is executed in order to allow the user to be provided with directions to a specific destination in a first display unit 110 of the foldable mobile device shown in FIG. 1. For example, the first image may correspond to a map showing the surrounding area of the point of departure having the requested path marked thereon.
(b) of FIG. 9 shows an example of a second image being displayed on the first and second folding areas 130 and 140 of the second display unit 120, when the user unfolds the foldable mobile device without performing any action, such as a zoom-in operation, while the foldable mobile device is in a state of having a map, which shows the surrounding area of the point of departure having the requested path marked thereon, being displayed on the touchscreen of the first display unit 110, as shown in (a) of FIG. 9. The second image shown in (b) of FIG. 9 may include the first image shown in (a) of FIG. 9 and a third image, which has not been displayed on the first display unit 110. This is because the size of the touchscreen of the first display unit 110 is smaller than the combined (or merged) touchscreen of the first and second folding areas 130 and 140 of the second display unit 120. For example, a map having a path from a point of departure to a point of arrival (or destination) fully marked thereon may be displayed on the second display unit 120 as the second image. In another example, the same image as that shown in (a) of FIG. 9 may be displayed on the touchscreen of the first folding area 130 of the second display unit 120, and a third image that has not been displayed on the first display unit 110 shown in (a) of FIG. 9 may be displayed on the touchscreen of the second folding area 140. At this point, according to the exemplary embodiment of the present specification, if POI information exists in the surrounding area of the requested path in (b) of FIG. 9, the POI information may also be displayed along with the corresponding images.
Meanwhile, in a display state as shown in (a) of FIG. 9, when the user unfolds the foldable mobile device without performing any action, such as a zoom-in operation, instead of (b) of FIG. 9, icons shown in (b) of FIG. 6 may be displayed on the first and second folding areas 130 and 140 of the second display unit 120 as the second image. The icons may correspond to icons of the Home screen, or the icons may correspond to icons of the Menu screen. More specifically, this corresponds to a case when the icons are being set up as the second image corresponding to a predetermined display mode. Herein, the second image corresponding to the predetermined display mode may be automatically set up by the system, or the second image corresponding to the predetermined display mode may be set up by the user using the Menu screen or Menu buttons.
(a) to (c) of FIG. 10 respectively show examples of a first image and a second image, when the foldable mobile device is unfolded after the first image, which is displayed on the first display unit 110, is zoomed-in.
More specifically, (a) of FIG. 10 shows an example of a first image being displayed on the touchscreen of the first display unit 110 in the portrait view mode (or vertical display mode), when an application, such as a pathfinder, is executed in order to allow the user to be provided with directions to a specific destination in a first display unit 110 of the foldable mobile device shown in FIG. 1.
When a zoom-in command is inputted to the first display unit 110 of (a) of FIG. 10 in order to enlarge the first image, an image that is zoomed-in (or enlarged) in accordance with the first zoom-in ratio is displayed on the first display unit 110, as shown in (b) of FIG. 10. At this point, as the first image is enlarged in accordance with the first zoom-in ratio and displayed on the first display unit 110, a portion of the first image disappears from the touchscreen of the first display unit 110. This is because the objects included in the first image are also enlarged in accordance with the first zoom-in ratio.
Since reference may be made to the description given in FIG. 7 on the method of inputting a zoom-in/zoom-out command and setting up first and second zoom-in ratios, detailed description of the same will be omitted in FIG. 10 for simplicity.
When the user unfolds the foldable mobile device, while the foldable mobile device is in a state of having the first image zoomed-in and displayed on the first display unit 110, as shown in (b) of FIG. 10, the first image prior to being zoomed-in is enlarged (or zoomed-in) by the second zoom-in ratio and then displayed on the second display unit 120 as the second image. Herein, if the first zoom-in ratio is equal to the second zoom-in ratio, the size of the objects included in the second image are the same as the size of the objects included in the first image, which is enlarged in the first display unit 110 in accordance with the first zoom-in ratio.
At this point, since the combined touchscreen of the second display unit 120 is larger than the touchscreen of the first display unit 110, a portion of the first image or the entire first image that disappears from the touchscreen of the first display unit 110 due to the zoom-in command may be additionally displayed on the second display unit 120. Additionally, in accordance with the zoom-in/zoom-out position within the touchscreen of the first display unit 110, the second display unit 120 may zoom-in a third image, which has not been displayed on the first display unit 110 shown in (a) of FIG. 10, and may additionally display the zoomed-in third image.
For example, the zoomed-in image identical to that shown in (b) of FIG. 10 is displayed on the touchscreen of the first folding area 130 of the second display unit 120, and a portion of the first image that has disappeared from the first display unit 110 due to the zoom-in operation and a third image that has not been displayed on the first display unit 110 prior to the zoom-in operation may be zoomed-in and then displayed on the second folding area 140.
Meanwhile, in the foldable mobile device of FIG. 7, FIG. 8, and FIG. 10, the second image being displayed on the second display unit 120 may include an image of an important point, to which the user has given significance prior to the zoom-in process, or POI information. For example, even in case the image of an important point, to which the user has given significance prior to the zoom-in process, has disappeared from first display unit 110 due to the zoom-in operation, when the foldable mobile device is unfolded, the image of the important point, to which the user has given significance prior to the zoom-in process, may be zoomed-in so as to be displayed on the second display unit 120. At this point, the image of the important point, to which the user has given significance prior to the zoom-in process, may be displayed at the center of the combined touchscreen of the second display unit 120, or may be displayed on any one of the touchscreen of the first folding area 130 and the touchscreen of the second folding area 140 of the second display unit 120. According to another exemplary embodiment of the present specification, a zoomed-in image respective to a location, at which the zoom-in command is inputted, within the touchscreen of the first display unit 110 may be set up to be displayed on the center of the combined touchscreen of the second display unit 120, when the foldable mobile device is unfolded.
Additionally, according to the exemplary embodiment of the present specification, in the foldable mobile device of FIG. 7, FIG. 8, and FIG. 10, when the first image is zoomed-in by a first zoom-in ratio with respect to a zoom-in command, so as to be displayed on the first display unit 110, the time consumed for performing the corresponding procedure is counted (or timed). And, according to the exemplary embodiment of the present specification, when the user unfolds the foldable mobile device within a predetermined period of time, based upon the image that is zoomed-in by the first zoom-in ratio and displayed on the first display unit 110, the original first image (i.e., the first image prior to being zoomed-in) is zoomed-in by the second zoom-in ratio, so as to be displayed on the second display unit 120 as the second image. If the user does not unfold the foldable mobile device before end of the predetermined time period, the image that has been zoomed-in by the first zoom-in ratio and displayed on the first display unit 110 is recovered to the image prior to being zoomed-in. Thereafter, if the user unfolds the foldable mobile device after the predetermined time period has elapsed (or ended), a second image corresponding to a predetermined display mode is displayed on the second display unit 120. Herein, the second image corresponding to a predetermined display mode may correspond to icons or may correspond to an image being in connection with the first image.
In the description provided above, exemplary embodiments of a foldable mobile device having two folding areas, as shown in FIG. 1, have been described in detail. Hereinafter, exemplary embodiments of a foldable mobile device having three folding areas, as shown in FIG. 3, will be described in detail.
(a) to (c) of FIG. 11 respectively show examples of an image, which is in connection with a first image, being displayed on a second display unit 320 as a second image, when a foldable mobile device is unfolded without any zoom-in operations after an execution image of a specific icon is displayed on a first display unit 310 of the foldable mobile device shown in FIG. 3. More specifically, (a) to (c) of FIG. 11 respectively show exemplary embodiments of the present specification of a case when the second image of a predetermined display mode corresponds to an image being in connection with the first image.
Most particularly, (a) of FIG. 11 shows an example of a first image being displayed on the touchscreen of the first display unit 310, when a location tracking application for searching my current position (or the current position of the user) or someone else's current position (or the current position of another user) is being executed from the first display unit 310 of the foldable mobile device shown in FIG. 3. For example, when my current position has been requested, the Current Position (or ‘You are here’) being indicated on the map becomes my current position (or the current position of the current user). In another example, when someone else's current position has been requested, the Current Position (or ‘You are here’) being indicated on the map becomes the current position of the particular person requested by me (i.e., the current user).
(b) of FIG. 11 shows an example of an image being in connection with the first image being displayed on a combined (or merged) touchscreen of the first and second folding areas 330 and 340, among first to third folding areas 330 to 350, of the second display unit 320 as the second image, when the user unfolds the foldable mobile device without performing any zoom-in operations, while the foldable mobile device is in a state of having the current position of an individual (or person) designated by the user being indicated (or marked) on a map, which is displayed on the touchscreen of the first display unit 310, as shown in (a) of FIG. 11. For example, if the right side portion of the foldable mobile device is not fully unfolded, or if the power of the third folding area 350 is turned off, the second image may not be displayed on the third folding area 350. According to the exemplary embodiment of the present specification, in the description of the present specification, in order to save power, at least one of the folding areas among the first to third folding areas 330 to 350 may be independently turned on/off.
(c) of FIG. 11 shows an example of an image being in connection with the first image being displayed on first to third folding areas 330 to 350 of the second display unit 320 as the second image, when the user completely (or fully) unfolds the foldable mobile device without performing any zoom-in operations, while the foldable mobile device is in a state of having the current position of an individual (or person) designated by the user being indicated (or marked) on a map, which is displayed on the touchscreen of the first display unit 310, as shown in (a) of FIG. 11, or when the user completely (or fully) unfolds the foldable mobile device, while the foldable mobile device is in a state of having the second image being displayed on the first and second folding areas 330 and 340 of the second display unit 320, as shown in (b) of FIG. 11.
Referring to (b) and (c) of FIG. 11, the first image that is displayed on the first display unit 310 shown in (a) of FIG. 11 is displayed on the second display unit 320 along with a third image, which has not been displayed on the first display unit 310. At this point, according to the exemplary embodiment of the present specification, since the current location (or position) corresponds to an important point designated by the user, when the foldable mobile device is unfolded, the current location must be displayed on the second display unit 320.
Meanwhile, according to the exemplary embodiment of the present specification, although it is not displayed in the first display unit 310, when POI information designated in advance by the user exists in the surrounding area of the current position, which is marked on the map, a third image including the POI information is displayed on the second display unit 320.
In (b) of FIG. 11, one type of POI information 361 is being displayed on the second folding area 340 of the second display unit 320. In (c) of FIG. 11, one type of POI information 361 is being displayed on the second folding area 340 of the second display unit 320, and two types of POI information 362 and 363 are being displayed on the third folding area 350 of the second display unit 320. (b) and (c) of FIG. 11 respectively show examples of one type or three types of POI information 361, 362, and 363 being located on the right side of the current position.
If at least one type of POI information is located on the left side of the current position, the section displaying the current position may be shifted rightward, in order to display the POI information located on the left side on the second display unit 120, and may then be displayed.
If there is no POI information designated by the user in the surroundings of the current position, the same image as that of (a) of FIG. 11 is displayed on the touchscreen of the first folding area 330 of the second display unit 320, as shown in (b) of FIG. 11, and a third image, which has not been displayed on the first display unit 310 shown in (a) of FIG. 11, may be displayed on the touchscreen of the second folding area 340.
In another example, as shown in (c) of FIG. 11, an image identical to that of (a) of FIG. 11 may be displayed on the touchscreen of the first folding area 330 of the second display unit 320, and a third image that has not been displayed on the first display unit 310 shown in (a) of FIG. 11 may be displayed on the touchscreens of the second and third folding areas 340 and 350 of the second display unit 320.

(a) and (b) of FIG. 12 and FIG. 13 respectively show examples of icons of a Home screen or Menu screen being displayed on a second display unit 320 as a second image, when a foldable mobile device is unfolded without any zoom-in operations after an execution image of a specific icon is displayed on a first display unit 310 of the foldable mobile device shown in FIG. 3. More specifically, (a) and (b) of FIG. 12 and FIG. 13 respectively show exemplary embodiments of the present specification of a case when the second image of a predetermined display mode corresponds to an icon image being in connection with the first image.
Since the content being displayed on the first display unit 310 of (a) of FIG. 12 is identical to that of (a) of FIG. 11, detailed description of the same will be omitted for simplicity.
(b) of FIG. 12 shows an example of icons of the Menu screen being displayed on each touchscreen of the first and second folding areas 330 and 340, among the first to third folding areas 330 to 350, of the second display unit 320 as the second image, when the user unfolds the foldable mobile device without performing any zoom-in operations, while the foldable mobile device is in a state of having the current position of an individual (or person) designated by the user being indicated (or marked) on a map, which is displayed on the touchscreen of the first display unit 310 of the foldable mobile device, as shown in (a) of FIG. 12. For example, if the right side portion of the foldable mobile device is not fully unfolded, or if the power of the third folding area 350 is turned off, the second image may not be displayed on the third folding area 350. According to the exemplary embodiment of the present specification, in the description of the present specification, in order to save power, at least one of the folding areas among the first to third folding areas 330 to 350 may be independently turned on/off.
FIG. 13 shows an example of icons of a Menu screen being displayed on each touchscreen of the first to third folding areas 330 to 350 of the second display unit 320 as the second image, when the user completely (or fully) unfolds the foldable mobile device without performing any zoom-in operations, while the foldable mobile device is in a state of having the current position of an individual (or person) designated by the user being indicated (or marked) on a map, which is displayed on the touchscreen of the first display unit 310 of the foldable mobile device, as shown in (a) of FIG. 12, or when the user completely (or fully) unfolds the foldable mobile device, while the foldable mobile device is in a state of having the second image being displayed on the first and second folding areas 330 and 340 of the second display unit 320, as shown in (b) of FIG. 12.
In another example, icons of the same Home screen as the first display unit 310 are displayed on the touchscreen of the first folding area 330 of the second display unit 320, and icons of another page of the Home screen are displayed on the second and third folding areas 340 and 350 of the second display unit 320. In yet another example, icons of the same Home screen as the first display unit 310 may be displayed on the touchscreen of the first folding area 330 of the second display unit 320, and icons of the Menu screen may be displayed on the second and third folding areas 340 and 350 of the second display unit 320. In yet another example, icons of remaining pages of the Home screen, which is displayed on the first display unit 310, may be displayed on at least one of the first folding area 330 to the third folding area 350 of the second display unit 320.
(a) to (d) of FIG. 14 respectively show examples of a first image and a second image, when the first image is zoomed-in and displayed in the first display unit 310 of the foldable mobile device, and when the foldable mobile device is unfolded afterwards.
More specifically, (a) of FIG. 14 shows an example of a first image being displayed on the touchscreen of the first display unit 310, when a location tracking application for searching my current position (or the current position of the user) or someone else's current position (or the current position of another user) is being executed from the first display unit 310 of the foldable mobile device shown in FIG. 3.
When a zoom-in command is inputted in order to enlarge the first image of the first display unit 310 shown in (a) of FIG. 14, the image that is zoomed-in (or enlarged) in accordance with the first zoom-in ratio is displayed on the first display unit 310 as shown in (b) of FIG. 14. At this point, as the first image is enlarged in accordance with the first zoom-in ratio and displayed on the first display unit 310, a portion of the first image disappears from the touchscreen of the first display unit 310. This is because the objects included in the first image are also enlarged in accordance with the first zoom-in ratio.
Since reference may be made to the description given in FIG. 7 on the method of inputting a zoom-in/zoom-out command and setting up first and second zoom-in ratios, detailed description of the same will be omitted in FIG. 14 for simplicity.
When the user partially unfolds the foldable mobile device, while the foldable mobile device is in a state of having the first image zoomed-in and displayed on the first display unit 310, as shown in (b) of FIG. 14, a second image is displayed on the first folding area 330 and the second folding area 340 of the second display unit 320, as shown in (c) of FIG. 14. For example, if the right side portion of the foldable mobile device is not fully unfolded, or if the power of the third folding area 350 is turned off, the second image may not be displayed on the third folding area 350. According to the exemplary embodiment of the present specification, in the present specification, in order to save power, at least one of the folding areas among the first to third folding areas 330 to 350 may be independently turned on/off.
According to an exemplary embodiment of the present specification, the second image being displayed on the second display unit 320 includes at least a portion of the first image, shown in (b) of FIG. 14. According to the exemplary embodiment of the present specification, in the description of the present specification, the first image that is displayed on the first display unit 310, as shown in (a) of FIG. 14, (i.e., the first image prior to being zoomed-in) is zoomed-in by the second zoom-in ratio, so as to be displayed on the first and second folding areas 330 and 340 as the second image.
At this point, according to the exemplary embodiment of the present specification, if the first zoom-in ratio is equal to the second zoom-in ratio, the size of the objects included in the second image are the same as the size of the objects included in the image, which is enlarged in the first display unit 310 in accordance with the first zoom-in ratio.
At this point, a portion of the first image or the entire first image that has disappeared from the touchscreen of the first display unit 310 due to the zoom-in operation may be additionally displayed on the second display unit 320. Additionally, in accordance with the zoom-in/zoom-out position within the touchscreen of the first display unit 310, the second display unit 320 may zoom-in a third image, which has not been displayed on the first display unit 310 shown in (a) of FIG. 14, and may additionally display the zoomed-in third image.
For example, the zoomed-in image identical to that shown in (b) of FIG. 14 is displayed on the touchscreen of the first folding area 330 of the second display unit 320, and a portion of the first image that has disappeared from the first display unit 310 due to the zoom-in operation and/or a third image that has not been displayed on the first display unit 310 prior to the zoom-in operation may be zoomed-in and then displayed on the touchscreen of the second folding area 340.

Thereafter, according to the exemplary embodiment of the present specification, if the user unfolds the foldable mobile device within a predetermined period of time, the original first image (i.e., the first image prior to being zoomed-in) is zoomed-in by the second zoom-in ratio, based upon the image zoomed-in by the first zoom-in ratio and displayed on the first display unit 310, thereby being displayed on the second display unit 320 as the second image. However, if the user does not unfold the foldable mobile device until the end of the predetermined period of time, the image that has been zoomed-in by the first zoom-in ratio and displayed on the first display unit 310 is recovered to the original image prior to being zoomed-in. Thereafter, when the user unfolds the foldable mobile device after the predetermined period of time, a second image respective to a predetermined display mode is displayed on the second display unit 320. Herein, the second image respective to the predetermined display mode may correspond to icons or may correspond to an image being in connected with the first image.
Moreover, in the foldable mobile device shown in FIG. 14 and FIG. 16, the zoom-in ratio may be set up differently for a case when the zoomed-in first image is displayed only in the first and second folding areas 330 and 340 of the second display unit 320 and for a case when the zoomed-in first image is displayed in all of the first to third folding areas 330 to 350 of the second display unit 320. According to an exemplary embodiment of the present specification, the zoom-in ratio of the first image, which is to be displayed in all of the first to third folding areas 330 to 350, is set up to be greater than the zoom-in ratio of the first image, which is to be displayed only in the first and second foldable areas 330 and 340. In this case, also, the zoom-in ratio of the first image, which is to be displayed only in the first and second folding areas 330 and 340 of the second display unit 320 shall be equal to or greater than the zoom-in ratio of the first image, which is zoomed-in in the first display unit 310 in accordance with an inputted zoom-in command. The above-described exemplary embodiment of the present specification may be more effective when applied to a case when the first image corresponds to a drawing, photo, webpage, document, and so on, each having a pre-decided horizontal ratio/vertical ratio.
Meanwhile, referring to FIG. 11 to FIG. 16, the second image may be displayed in the first and second folding areas 330 and 340 of the second display unit 320, only when the foldable mobile device is fully (or completely) unfolded. More specifically, when the foldable mobile device is fully (or completely) unfolded, the process of displaying the second image only in the first and second folding areas 330 and 340 of the second display unit 320 may be omitted. This process may be omitted in accordance with the user's selection, when the user seeks to view the second image being displayed on the touchscreen of the first to third folding areas 330 to 350 firsthand, or this process may be omitted when the foldable mobile device is fully unfolded up to the third folding area 350 within a predetermined period of time. Alternatively, this process may also be omitted in accordance with the processing capability of the processor.
FIG. 17 illustrates a flow chart showing a method of controlling a display of the foldable mobile device according to an exemplary embodiment of the present specification.
More specifically, when a specific icon is selected from the first display unit of the foldable mobile device and then executed, the corresponding image respective to the execution of the selected icon is displayed on the first display unit as a first image (S511). Accordingly, the foldable mobile device verifies whether or not a zoom-in command is inputted by the user in order to enlarge the first image, which is displayed on the first display unit (S512). Herein, since the method for inputting the zoom-in command has been described above in FIG. 7, reference may be made to FIG. 7, and, therefore, the detailed description of the same will be omitted herein for simplicity.
When it is verified in step S512 that the zoom-in command has been inputted, the first image is zoomed-in by the first zoom-in ratio and then displayed on the first display unit (S513). In step S513, when the zoomed-in first image is displayed on the first display unit, the timed is counted (or timed) (S514). Thereafter, it is verified whether or not the foldable mobile device is unfolded before the counted (or timed) time reaches the end of a predetermined time period (S515). If the foldable mobile device is not unfolded until the end of the predetermined time period, the first image being zoomed-in and displayed on the first display unit is recovered to its original (or initial) state prior to being zoomed-in, thereby being displayed on the first display unit.
In step S515, when it is verified that the foldable mobile device is unfolded within the predetermined time period, a second image including the first image, which is zoomed-in by the second zoom-in ratio, is displayed on the second display unit (S516). In the above-described process steps, since the method for setting-up the first zoom-in ratio and the second zoom-in ratio has been described above in FIG. 7, reference may be made to FIG. 7, and, therefore, the detailed description of the same will be omitted herein for simplicity.

The first and second display units 1190a and 1190b may be input at least one touch gesture through a body of the user (e.g., fingers including a thumb) or a sensible input means (e.g., a stylus pen). The user interface may include a predetermined touch area, a soft key and a soft menu. The first and second display units 1190a and 1190b may transmit an electrical signal corresponding to at least one touch gesture being input through the user interface to the display controller 1195. Furthermore, the first and second display unit 1190a and 1190b may detect continuous touch motions and transmit electrical signals corresponding to continuous or discontinuous touch motions to the display controller 1195. The first and second display units 1190a and 1190b may be implemented in, for example, a resistive type, a capacitive type, an infrared type or an acoustic wave type.
The display controller 1195 converts an electrical signal received from the first display unit 1190a and the second display unit 1190b into a digital signal (e.g., X and Y coordinates), and transmits the digital signal to the controller 1110. The controller 1110 may control the first display unit 1190a and the second display unit 1190b by using the digital signal received from the display controller 1195. For example, the controller 1110 may cause a short-cut icon displayed on the first display unit 1190a and the second display unit 1190b to be selected or executed in response to a touch. The display controller 1195 may be included in the controller 1110.
The touch gesture according to the present specification is not limited to a direct contact between the first and second display units 1190a and 1190b and a user's body or a touchable input means and may include a non-contact (for example, a case where a detectable interval between the first and second display units 1190a and 1190b and the user's body or the touchable input means is 1 cm or shorter). The detectable interval of the first and second display units 1190a and 1190b may be changed according to a capability or a structure of the smart phone 1100.
In an exemplary embodiment, the touch gesture may include all types of user gestures which can be detected by the portable device through a direct contact or a close approach to the touch screen. For example, the touch gesture corresponds to a user's action of selecting one position or a plurality of continuous positions on the touch screen by using a finger of a right hand or left hand (particular, an index finger), a thumb, or an object (for example, a stylus pen) which can be detected by the touch screen, and may include actions such as a touch, a contact, a release of the touch, a tap, a contact and rotate, a pinch, a spread, a touch drag and the like. Here, the touch drag corresponds to a gesture of moving a finger or a thumb in a predetermined direction in a state where the finger, the thumb, or a stylus pen contacts the touch screen, and may include, for example, gestures such as a touch and drag, a flick, a swipe, a slide, a sweep and the like. A contact state with the touch screen may include a state where the finger, the thumb, or the stylus pen directly contacts the touch screen or closely approaches the touch screen without a direct contact.
The smart phone 1100 is a device for executing an application, a widget, and a function which is stored in the storage unit and can be executed by the controller 1110 through the touch screen. In general, the touch screen provides application, widgets, functions, and graphic objects (that is, soft key or short-cut icon) corresponding to a group thereof, and the portable device executes a corresponding application, widget, or function in response to the detection of the touch gesture of the user on each graphic object.
Here, the widget refers to a mini application which is downloaded and used by the user or can be generated by the user, and includes, for example, a weather widget, a stock widget, a calculator widget, an alarm clock widget, a dictionary widget and the like. A short-cut icon for executing the widget may provide simple advance information through a corresponding widget application. For example, an icon of the weather widget simply provides a current temperature and a weather symbol and a widget application executed through a touch of the icon provides much more information such as weather in each period/area. The application in this specification includes a widget based application and a non-widget based application.
Meanwhile, a first image may be displayed in the first display unit 1190a of the smart phone 1100 in accordance with the execution of a specific application. At this point, if the smart phone 1100 is unfolded without any zoom-in operations, a second image corresponding to a predetermined mode (or display mode) is displayed on the second display unit 1190b. Herein, the second image corresponding to the predetermined display mode may correspond to icons of a Home screen or a Menu screen, or may correspond to an image being in connection with the first image. And, if the first image corresponds to an image including a map, and if the second image corresponding to the predetermined display mode corresponds to an image being in connection with the first image, a third image including point of interest (POI) information may also be displayed on the second display unit 1190b. Meanwhile, in a state when the first image is displayed on the first display unit 1190a of the smart phone 1100, if a zoom-in command is inputted by the user in order to enlarge the first image, due to the control of the controller 1110, the first display unit 1190a enlarges the first image by a first zoom-in ratio and displays the enlarged first image. At this point, since the method for inputting the zoom-in command has already been described above in FIG. 7, and since reference may be made to FIG. 7, detailed description of the same will hereinafter be omitted for simplicity. For example, when a gesture of spreading out two fingers in inputted to the first display unit 1190a, the controller 1110 recognizes (or identifies) the inputted gesture as the zoom-in command.
After the first image, which is enlarged by the first zoom-in ratio, is displayed on the first display unit 1190a before a predetermined time is elapsed, the controller 1110 determines whether or not the smart phone 1100 is being unfolded. If the smart phone 1100 is not unfolded until the predetermined time is elapsed, due to the control of the controller 1100, the first display unit 1190a recovers the displayed first image, which is zoomed-in to the first zoom-in ratio, to its initial state prior to being zoomed-in (or enlarged) and displays the recovered first image.
Meanwhile, if the smart phone 1100 is unfolded before the predetermined time is elapsed (or expired), due to the control of the controller 1110, the second display unit 1190b zooms-in the original first image to a second zoom-in ratio and displays the newly zoomed-in image as the second image. For example, the second display unit 1190b displays the first image, which is zoomed-in to a second zoom-in ratio that is equal to the first zoom-in ratio or greater than the first zoom-in ratio, as a second image. Since the method for setting-up (or determining) the first zoom-in ratio and the second zoom-in ratio has already been described above in FIG. 7, and since reference may be made to FIG. 7, detailed description of the same will hereinafter be omitted for simplicity.
At this point, the sensor module 1170 includes at least one sensor detecting the state of the smart phone 1100, and, for example, the foldable mobile device senses the folded/unfolded state of the smart phone 1100. And, based upon the sensing result of the sensor module 1170, the controller 1110 controls the display of the first and second display units 1190a and 1190b. 
According to an exemplary embodiment of the present specification, if the smart phone 1100 corresponds to a foldable mobile device having two folding areas, as shown in FIG. 1, the second image is displayed on a first folding area and a second folding area of the second display unit 1190b. According to the exemplary embodiment of the present specification, specific parts that have not been described herein follow the description given with reference to FIG. 5 to FIG. 10.
According to another exemplary embodiment of the present specification, if the smart phone 1100 corresponds to a foldable mobile device having three folding areas, as shown in FIG. 3, the second image is displayed in at least two folding areas, among the first to third folding areas, of the second display unit 1190b. Herein, according to the exemplary embodiment of the present specification, portions of the present specification that are not described herein shall follow the contents described in FIG. 11 to FIG. 16.
If a flexible mobile device can be folded/unfolded, the above-described exemplary embodiments of the present specification may also be applied to the flexible mobile device.
As described above, when the foldable mobile device according to the present specification is in a folded state, by zooming-in an image that is being displayed on the first display unit in accordance with a zoom-in command, and by allowing an image that is zoomed-in at a zoom-in ratio, which is equal to or greater than the zoom-in ratio of the zoomed-in image being displayed on the first display unit, to be displayed on the second display device, when the foldable mobile device is unfolded, the user's needs and request to view an image that is more enlarged than the original image through a larger display screen may be quickly and easily satisfied.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present specification without departing from the spirit or scope of the specifications. Thus, it is intended that the present specification covers the modifications and variations of this specification provided they come within the scope of the appended claims and their equivalents.
