Description

DISPLAY DEVICE AND METHOD OF CONTROLLING THE SAME

The present disclosure relates to a display device and a method of controlling the same, and more particularly, to a display device that controls displaying of a window in which an application is executed, and a method of controlling the display device.

A desktop computer has at least one display device (for example, a monitor). A mobile device (for example, a mobile phone, a smart phone, or a tablet Personal Computer (PC)) using a touch screen has one display device.

A user of the desktop computer may divide a screen of the display device according to a working environment (for example, horizontally or vertically divide the screen while displaying a plurality of windows) and use the divided screens. When a web browser is executed, the user can move in an up or down direction of the web page by using a page up button or a page down button arranged in a keyboard. When the user uses a mouse instead of the keyboard, the user can move in the up or down direction of the web page by selecting a scroll bar located in a side part of the web page by using a cursor. Further, the user can move in the up or down direction of the web page by selecting a top button displayed as a text or an icon located in a bottom part of the web page.

The mobile device has a smaller size of the displayed screen in comparison with the desktop computer and a limitation in an input. The user has a difficulty in dividing and then using the mobile device.

Further, the mobile device can execute various applications such as basic applications produced by a manufacturer of the mobile device and then installed in the mobile device and additional applications downloaded from an application selling site through the Internet.

Therefore, tens of thousands to hundreds of thousands of applications are currently provided to the mobile apparatuses free of charge or at a cost according to types of the mobile apparatuses.

Although various applications which simulate consumers' curiosity and satisfy consumers demands are provided to the mobile device, since the mobile device is provided to have a portable size, it has a limitation in a size of a display device and a User Interface (UI) thereof. Accordingly, the users feel it is inconvenient to execute a plurality of applications in the mobile device.

Accordingly, a technology for displaying a plurality of windows on a single display and a technology for easily adjusting a size of the plurality of windows are required.

Therefore, the present disclosure has been made in view of the above-mentioned problems, and an aspect of the present disclosure is to provide a display device that can easily adjust a size of a plurality of windows on a single display, and a method of controlling the display device.

In accordance with an aspect of the present disclosure, there is provided a method of controlling a display device including a touch screen, the method including: displaying, on the touch screen, a plurality of windows executing applications, respectively, such that the windows do not overlap each other; displaying a plurality of boundary lines differentiating the plurality of windows, and a center button disposed at an intersection point of the plurality of boundary lines; receiving, through the touch screen, an input of a window size change command to change a size of at least one of the plurality of windows; and resizing and displaying at least one of the plurality of windows in correspondence to the window size change command.

In accordance with another aspect of the present disclosure, there is provided a display device including: a touch screen that displays a plurality of windows executing applications, respectively, such that the windows do not overlap each other, and displays a plurality of boundary lines differentiating the plurality of windows and a center button disposed at an intersection point of the plurality of boundary lines; and a controller that resizes and displays at least one of the plurality of windows in correspondence to a window size change command to change a size of at least one of the plurality of windows, when the window size change command is input on the touch screen.

As described above, the present disclosure provides a display device and a method of controlling the display device which can easily adjust a size of a plurality of windows on a single display. Accordingly, a user can adjust the size of the plurality of windows simultaneously or separately so that user convenience can be maximized.

Further, the touch screen controller 195 may be included in the controller 110.

FIGS. 2a to 2e illustrate a display device according to various embodiments of the present disclosure. It will be understood by those skilled in the art that a display device 200 may be implemented in various forms such as an ordinary Television (TV), an internet TV, and a medical data display device, as well as the mobile device described above in relation to FIG. 1. Namely, any device provided with a unit capable of displaying a rendered image may be used as the display device without limitation.

FIG. 2a illustrates a display device according to an embodiment of the present disclosure. A touch screen of the display device is divided into four areas, and different windows are displayed in the respective areas. A controller (not illustrated) of the display device 200 may set a layout such that a screen is divided into four equal areas. More specifically, the controller (not illustrated) may set first, second, third, and fourth areas. The controller (not illustrated) may set a first boundary line 211 between the first and second areas, a second boundary line 212 between the third and fourth areas, a third boundary line 213 between the first and third areas, and a fourth boundary line 214 between the second and fourth areas. Here, the first and second boundary lines 211 and 212 may configure one line segment, and the third and fourth boundary lines 213 and 214 may configure one line segment. The controller (not illustrated) sets the first to fourth areas not to overlap each other. For example, as illustrated in FIG. 2a, the controller (not illustrated) sets the first area on an upper left side of the screen, the second area on an upper right side of the screen, the third area on a lower left side of the screen, and the fourth area on a lower right side of the screen. The controller (not illustrated) sets the first and second boundary lines 211 and 212 to divide the screen into left and right areas, and sets the third and fourth boundary lines 213 and 214 to divide the screen into upper and lower areas.

The controller (not illustrated) displays windows for executing an application in the respective areas. For example, the controller (not illustrated) displays a first window 201 for executing an application A in the first area, a second window 202 for executing an application B in the second area, a third window 203 for executing an application C in the third area, and a fourth window 204 for executing an application D in the fourth area.

Meanwhile, the controller (not illustrated) displays a center button 210 at a point where the first and second boundary lines 211 and 212 intersect with the third and fourth boundary lines 213 and 214. The center button 210 will be described below more specifically.

The window may be an area including an execution screen of a particular application, a title bar for the executed application, and a control area. Objects related to the application may be displayed on the execution screen of the application. The objects may be formed in various shapes such as a text, a figure, an icon, a button, a check box, a picture, a video, a web, a map and the like. When a user touches the corresponding object, a predetermined function or event for the object may be performed in a corresponding application. The object may be referred to as a view according to an operating system. The title bar may include at least one control key for controlling a display of the window. For example, the control key may be a window display minimizing button, a window display maximizing button, or a window closing button.

Meanwhile, applications are programs independently implemented by a manufacturer of the display device 200 or an application developer. Accordingly, a pre-execution of one application is not required to execute another application. Further, although one application ends, another application can be continuously executed.

The applications are distinguished from a complex function application (or a dual application) generated by adding some functions (a memo function and a message transmission/reception function) provided by one application to functions of another application in that the applications are independently implemented programs. However, the complex function application is a single application newly produced to have various functions and thus has differences from conventional applications. Accordingly, the complex function application provides only limited functions, without providing various functions like the conventional applications. Further, users have the burden of separately purchasing such a new complex function application.

Referring to FIG. 2b, a user 1 may increase a size of the fourth window 204 for executing the application D. For example, the user 1 may touch the second boundary line 212 and then may input a window size change command 215 to drag the second boundary line 212 leftward to a first end point 216. The controller (not illustrated) may determine in correspondence to the drag gesture 215 input on the touch screen that the window size change command has been input. The controller (not illustrated) analyzes the input window size change command, and resizes and displays the windows. For example, the controller (not illustrated) may control such that the third and fourth areas are displayed while a horizontal length of the third area is decreased and a horizontal length of the fourth area is increased by the input window size change command. More specifically, the controller (not illustrated) may determine, based on the fact that a start point of the drag gesture 215 is on the second boundary line 212, that the window size change command to change the horizontal lengths of the third and fourth areas has been input. Further, the controller (not illustrated) may determine, based on the fact that the drag gesture 215 is made leftward, that the window size change command to decrease the horizontal length of the third area and increase the horizontal length of the fourth area has been input. In addition, the controller (not illustrated) may determine a degree of a change in the window size by the window size change command, based on a location of the end point 216 of the drag gesture 215. As described above, the controller (not illustrated) may determine, based on the input window size change command, at least one of a target window to be changed in size, a change in a horizontal or vertical length of the corresponding window, and a degree of the change. Table 1 illustrates a change in a window size according to a window size change command.

Table 1 Drag start point Drag direction Change in Window size 1st Boundary line Leftward Decrease in horizontal length of 1st area &Increase in horizontal length of 2nd area Rightward Increase in horizontal length of 1st area &Decrease in horizontal length of 2nd area 2nd Boundary line Leftward Decrease in horizontal length of 3rd area &Increase in horizontal length of 4th area Rightward Increase in horizontal length of 3rd area &Decrease in horizontal length of 4th area 3rd Boundary line Upward Decrease in vertical length of 1st area &Increase in vertical length of 3rd area Downward Increase in vertical length of 1st area &Decrease in vertical length of 3rd area 4th Boundary line Upward Decrease in vertical length of 2nd area &Increase in vertical length of 4th area Downward Increase in vertical length of 2nd area &Decrease in vertical length of 4th area

When analyzing the window size change command, the controller (not illustrated) may change the horizontal lengths of the third and fourth windows 223 and 224 based on the window size change command, and may display the third and fourth windows 223 and 224, as illustrated in FIG. 2c. More specifically, the controller (not illustrated) may reset a second boundary line 217 to the end point 216 of the drag gesture 215 input by the user 1. The controller (not illustrated) may change the horizontal lengths of the third and fourth windows 223 and 224 based on the second boundary line 217, and may display the third and fourth windows 223 and 224. Meanwhile, the controller (not illustrated) displays the third window 223 in the size-changed third area and the fourth window 224 in the size-changed fourth area. In this case, the controller (not illustrated) resizes and displays the third window 223, namely, an execution screen of the application C in correspondence to the size-changed third area. The controller (not illustrated) resizes and displays the fourth window 224, namely, an execution screen of the application D in correspondence to the size-changed fourth area. For example, the controller (not illustrated) may display the execution screen of the application C in the entire third area. In this case, the controller (not illustrated) may reduce and display the execution screen of the application C in the same rate as the third area. Further, the controller (not illustrated) may display only a portion of the execution screen of the application C. For example, the controller (not illustrated) may display only a right side portion of the execution screen of the application C, thereby creating an effect that the application C is pushed to a left side. Furthermore, the controller (not illustrated) may also display the third window 223 at a portion of the third area, while maintaining a horizontal to vertical ratio of the execution screen of the application C. The controller may leave the remaining area of the third area empty, in which the third window 223 is not displayed in the remaining area. Moreover, the controller (not illustrated) may change the execution screen of the application to another screen, and may display the another screen. The controller (not illustrated) may also change and display the execution screen of the application in correspondence to an area reduced or enlarged in various ways. This will be described below more specifically.

Meanwhile, the controller (not illustrated) may form a view having a predetermined thickness while the boundary line serving as a center line of the thickness, and may control such that the view is not displayed. Since the boundary line is displayed as a line, it may be difficult to determine whether the boundary line is touched. Accordingly, when the view having the predetermined thickness is touched, the controller (not illustrated) may determine that the boundary line is touched.

As described above, the display device 200 provides a function of making the user 1 change the size of the two areas simultaneously and easily.

FIGS. 2d and 2e illustrate a process of changing a window size according to another embodiment of the present disclosure. As illustrated in FIG. 2d, a user 1 may input a window size change command 231 on a touch screen. In the embodiment of FIG. 2d, the window size change command 231 may be an upward drag gesture from a third boundary line 213 to a second end point 232.

The controller (not illustrated) may analyze the input window size change command 231, and may control such that first and third areas are displayed as illustrated in FIG. 2e while a vertical length of the first area is decreased and a vertical length of the third area is increased. The controller (not illustrated) resizes and displays first and third windows 241 and 243 in correspondence to the changed window display spaces.

Further, the controller (not illustrated) may set a third boundary line 218 as the second end point 232 to change the size of the first and third areas.

FIG. 3a is a flowchart illustrating a method of controlling a display device according to an embodiment of the present disclosure.

The display device may set a plurality of window display spaces such as, for example, first to fourth areas of FIG. 2a to display a plurality of windows, in step S301. The display device may set, for example, at least one boundary line, and thereby may set the plurality of window display spaces.

When the plurality of window display spaces are set, the display device may receive an input of a window size change command to drag the boundary line, in step S303. The display device may determine in step S305 whether a starting boundary line for the drag is a boundary line between left and right window display spaces or a boundary line between upper and lower window display spaces. When the starting boundary line for the drag is the boundary line between the left and right window display spaces (S305-Y), the display device may move the boundary line between the left and right window display spaces to an end point of the drag, in step S307. In addition, the display device may change a horizontal length of the window display spaces in step S309, while a vertical length of the window display spaces adjacent to the corresponding boundary line is fixed. For example, the display device may decrease a horizontal length of a first window adjacent to the corresponding boundary line, and at the same time, may increase a horizontal length of a second window adjacent to the corresponding boundary line. When the starting boundary line for the drag is the boundary line between the upper and lower window display spaces (S305-Y), the display device may move the boundary line between the upper and lower window display spaces to the end point of the drag, in step S311. Further, the display device may change a vertical length of the window display spaces in step S313, while a horizontal length of the window display spaces adjacent to the corresponding boundary line is fixed. For example, the display device may decrease a vertical length of a first window adjacent to the corresponding boundary line, and at the same time, may increase a vertical length of a second window adjacent to the corresponding boundary line.

FIG. 3b is a flowchart illustrating a method of controlling a display device according to another embodiment of the present disclosure. Since the steps S301 and S303 have been described above with reference to FIG. 3a, descriptions thereof will be omitted below.

The display device may move the corresponding boundary line to an end point of the drag, in step S323. After moving the corresponding boundary line, the display device may change a size of window display spaces based on the moved boundary line, in step S325. Namely, unlike the embodiment of FIG. 3a, the display device may reset the window display spaces based on at least one boundary line after the movement of the boundary line. The display device displays windows in the reset window display spaces, respectively.

FIGS. 4a to 4g illustrate a process of changing a window size according to another embodiment of the present disclosure.

FIG. 4a illustrates a display device according to an embodiment of the present disclosure. A touch screen of the display device is divided into four areas, and different windows are displayed in the respective areas. A controller (not illustrated) of the display device 400 may set a layout such that a screen is divided into four equal areas. More specifically, the controller (not illustrated) may set first, second, third, and fourth areas. The controller (not illustrated) may set a first boundary line 411 between the first and second areas, a second boundary line 412 between the third and fourth areas, a third boundary line 413 between the first and third areas, and a fourth boundary line 414 between the second and fourth areas.

The controller (not illustrated) displays windows for executing an application in the respective areas. For example, the controller (not illustrated) displays a first window 401 for executing an application A in the first area, a second window 402 for executing an application B in the second area, a third window 403 for executing an application C in the third area, and a fourth window 404 for executing an application D in the fourth area.

Meanwhile, the controller (not illustrated) displays a center button 410 at a point where the first and second boundary lines 411 and 412 intersect with the third and fourth boundary lines 413 and 414.

As illustrated in FIG. 4B, a user 1 may input, as a window size change command, a leftward drag gesture 421 from the center button 410 to a first end point 422. As illustrated in FIG. 4c, the controller (not illustrated) may change a location of the center button 410 to the first end point 422, and may display the button 410. In addition, the controller (not illustrated) may reset and display the boundary lines 411 to 414 based on the center button 410. For example, the controller (not illustrated) resets the first boundary line 411 from the center button 410 to an upper side, the second boundary line 412 from the center button 410 to a lower side, the third boundary line 413 from the center button 410 to a left side, and the fourth boundary line 414 from the center button 410 to a right side. Further, the controller (not illustrated) resizes and displays the first to fourth areas based on the reset boundary lines 411 to 414. Namely, in contrast to the embodiment of FIG. 2c, a size of all the window display areas may be changed together in the embodiment of FIG. 4B.

FIG. 4d illustrates a method of changing a window size according to another embodiment of the present disclosure. As illustrated in FIG. 4d, a user may input, as a window size change command, an upward drag gesture 435 from the center button 410 to a second end point 436. As illustrated in FIG. 4E, the controller (not illustrated) may change a location of the center button 410 to the second end point 436, and may display the button 410. In addition, the controller (not illustrated) may reset and display the boundary lines 411 to 414 based on the center button 410. The controller (not illustrated) resizes and displays the first to fourth areas based on the reset boundary lines 411 to 414.

FIG. 4f illustrates a method of changing a window size according to another embodiment of the present disclosure. As illustrated in FIG. 4f, a user may input, as a window size change command, an upper-left drag gesture 464 from the center button 410 to a third end point 465. As illustrated in FIG. 4g, the controller (not illustrated) may change a location of the center button 410 to the third end point 465, and may display the button 410. In addition, the controller (not illustrated) may reset and display the boundary lines 411 to 414 based on the center button 410. The controller (not illustrated) resizes and displays the first to fourth areas based on the reset boundary lines 411 to 414. Further, the controller (not illustrated) may resize and display windows in correspondence to a size of the reset first to fourth areas.

FIG. 5 is a flowchart illustrating a method of changing a window size according to an embodiment of the present disclosure.

The display device may set a plurality of window display spaces such as, for example, first to fourth areas of FIG. 4a to display a plurality of windows, in step S501. The display device may set, for example, at least one boundary line, and thereby may set the plurality of window display spaces. Here, a center button may be formed at an intersecting point of the at least one boundary line.

When the plurality of window display spaces are set, the display device may receive an input of a window size change command to drag the center button, in step S503. The display device moves the center button to an end point of the drag, and thereafter resets boundary lines based on the moved center button, in step S505. The display device resets a size of the windows based on the at least one reset boundary line, and then displays the windows, in step S507.

FIGS. 6a to 6c illustrate a case in which a screen is reduced.

Referring to FIG. 6a, a display device 600 displays first to fourth windows 601 to 604 on a touch screen. The third window 603 may execute a gallery application that displays a specific image file. As illustrated in FIGS. 6b and 6c, a user may reduce the third window 603 by dragging a center button.

A controller (not illustrated) reduces a horizontal size of the third window 603 based on the input window size change command, and displays the third window 603. As illustrated in FIG. 6b, the controller (not illustrated) may decrease a horizontal length of the third window 603 to display the third window 603. The controller (not illustrated) controls such that only a portion of an image is displayed as the size of the third window 603 is reduced. For example, the controller (not illustrated) controls such that a right side portion of the image is not displayed, thereby creating an effect that the right side portion of the image is hidden due to the size reduction of the third window 603. Meanwhile, when the size of the third window 603 is further reduced as illustrated in FIG. 6c, the display device 600 displays only a portion of the image in correspondence to the size reduction. More specifically, the controller (not illustrated) may control the display device 600 to display only a portion of the image such that the image is hidden by a boundary line.

FIG. 6d illustrates a process of changing a window size according to another embodiment of the present disclosure. As illustrated in FIG. 6d, the controller (not illustrated) may change a horizontal to vertical ratio of an image to display the image in the entire reduced third window 603.

FIGS. 6e and 6f illustrate a process of changing a window size according to another embodiment of the present disclosure.

As illustrated in FIG. 6e, a controller (not illustrated) reduces horizontal and vertical sizes of a third window 603 based on the input window size change command, and displays the third window 603. The controller (not illustrated) may decrease horizontal and vertical lengths of the third window 603 to display the third window 603, as illustrated in FIG. 6e. As the size of the third window 603 is reduced, the controller (not illustrated) may also reduce and display an image at the same rate as the third window 603. That is, the reduced image may have the same scale as the image prior to the reduction. However, when an image is reduced in size smaller than a preset threshold value, a user may have difficulty in recognizing the image. Accordingly, when the window is reduced in size smaller than the threshold value, as illustrated in FIG. 6f, the controller (not illustrated) may display only a portion of the image. More specifically, the controller (not illustrated) may display only a portion of the image such that the image is hidden by a boundary line.

FIGS. 6g to 6k illustrate a process of moving a screen according to various embodiments of the present disclosure. As illustrated in FIG. 6g, a user 1 may input a screen movement command 670 on a third window 625. The screen movement command 670 may be a rightward drag. However, the rightward drag is merely illustrative. When the screen movement command 670 is input, a controller (not illustrated) may move and display the screen displayed on the third window 625 in response to the screen movement command 670. As illustrated in FIG. 6h, the controller (not illustrated) may display a screen 680 moved leftwards on the third window. Alternatively, as another embodiment, as illustrated in FIG. 6i, the controller (not illustrated) may generate and display a scroll bar 671. The scroll bar 671 may be moved by a user, and a screen may be moved and displayed in correspondence to a movement of the scroll bar 671. For example, as illustrated in FIG. 6j, a user 1 may input a screen movement command that is a rightward drag 672 on the scroll bar 671. As illustrated in FIG. 6k, the controller (not illustrated) may display the screen 680 moved rightward on the third window in response to the input screen movement command. In addition, when a preset time interval passes after the screen is moved, the controller (not illustrated) may not display the scroll bar 671. Meanwhile, the scroll bar 671 displayed at an upper side of the third window and moved leftward and rightward is merely illustrative, and the scroll bar 671 may also be displayed at a left side or right side of the third window, and may be moved upward and downward.

As another embodiment of the present disclosure, as illustrated in FIG. 6l, the controller may generate and display a directional navigator 673. A screen may be moved and displayed in a direction input by a user through the directional navigator 673. For example, as illustrated in FIG. 6m, a user 1 may input a screen movement command that is a rightward touch 674 on the directional navigator 673. As illustrated in FIG. 6n, the controller (not illustrated) may display a screen 680 moved rightward on a third window in response to the input screen movement command. In addition, when a preset time interval passes after the screen is moved, the controller (not illustrated) may not display the directional navigator 673. Meanwhile, the directional navigator 673 displayed at a center of the third window is merely illustrative, and the directional navigator 673 may also be displayed at a left, right, upper, or lower side of the third window.

FIGS. 7a to 7c illustrate a case in which a screen is reduced according to another embodiment of the present disclosure.

Referring to FIG. 7a, a display device 700 displays first to fourth windows 701 to 704 on a touch screen. The third window 703 may execute a gallery application that displays a specific image file. As illustrated in FIGS. 7b and 7c, a user may reduce the third window 703 by dragging a center button.

A controller (not illustrated) decreases a horizontal length of the third window 703 based on the input window size change command, and displays the third window 703. As illustrated in FIG. 7b, the controller (not illustrated) may decrease the horizontal length of the third window 703 to display the third window 703. The controller (not illustrated) controls such that only a portion of an image is displayed as the size of the third window 703 is reduced. For example, the controller (not illustrated) controls such that a left side portion of the image is not displayed, thereby creating an effect that the image is pushed leftward due to the size reduction of the third window 703. Meanwhile, when the size of the third window 703 is further reduced as illustrated in FIG. 7c, the display device 700 displays only a portion of the image in correspondence to the size reduction. More specifically, the controller (not illustrated) may control such that the image is displayed as if pushed out by a boundary line.

FIGS. 7d and 7e illustrate a process of changing a window size according to another embodiment of the present disclosure.

As illustrated in FIG. 7d, a controller (not illustrated) reduces horizontal and vertical sizes of a third window 703 based on the input window size change command, and displays the third window 703. The controller (not illustrated) may decrease horizontal and vertical lengths of the third window 703 to display the third window 703, as illustrated in FIG. 7d. As the size of the third window 703 is reduced, the controller (not illustrated) may also reduce and display an image at the same rate as the third window 703. That is, the reduced image may have the same scale as the image prior to the reduction. However, when an image is reduced in size smaller than a preset threshold value, a user may have difficulty in recognizing the image. Accordingly, when the window is reduced in size smaller than the threshold value, as illustrated in FIG. 7e, the controller (not illustrated) may display only a portion of the image. More specifically, the controller (not illustrated) may control such that the image is displayed as if pushed out by a boundary line.

FIG. 7f is a flowchart illustrating a method of controlling a display device according to an embodiment of the present disclosure.

The display device may set a plurality of window display spaces such as, for example, first to fourth areas of FIG. 2a to display a plurality of windows, in step S771. The display device may set, for example, at least one boundary line, and thereby may set the plurality of window display spaces.

When the plurality of window display spaces are set, the display device may receive an input of a window size change command such as a gesture to drag a boundary line or a center button, in step S773.

The display device grasps the windows to be changed in size, based on the input window size change command. The display device may identify an attribute of an application executed in the windows to be changed in size, in step S775. More specifically, the display device may identify a size change attribute of an execution screen of the application executed in the windows to be changed in size, and attributes of applications are illustrated in Table 2 below.

Table 2 Application Attribute 1st Application Size & Horizontal to Vertical Ratio are changeable. 2nd Application Size is changeable.Horizontal to Vertical Ratio is unchangeable. 3rd Application Size & Horizontal to Vertical Ratio are unchangeable: A portion of execution screen is hidden when window size is changed. 4th Application Size & Horizontal to Vertical Ratio are unchangeable: A portion of execution screen is pushed out when window size is changed.

As illustrated above, the attribute of the application may relate to a change in at least one of a size and a horizontal to vertical ratio of the execution screen of the application. The display device may identify that an execution screen of the first application is changeable in size and horizontal to vertical ratio. The display device may identify that an execution screen of the second application is changeable in size and is unchangeable in horizontal to vertical ratio. The display device may identify that an execution screen of the third application is unchangeable in size and horizontal to vertical ratio. Meanwhile, when a window size is changed, the third application displays only a portion of the application execution screen, in which case the application execution screen may be displayed as illustrated in FIGS. 6a to 6c, while being hidden by a boundary line. The display device may identify that an execution screen of the fourth application is unchangeable in size and horizontal to vertical ratio. Meanwhile, when a window size is changed, the fourth application displays only a portion of the application execution screen, in which case the application execution screen may be displayed as if pushed out as illustrated in FIGS. 7a to 7c. At a time point when the respective applications are installed, the display device may identify meta data of the applications, and may identify and store an attribute included in the meta data.

The display device generates and displays an application execution screen in the corresponding window, based on the identified attribute of the applications, in step S777, and resizes and displays the window based on a window size change command, in step S779.

As described above, the display device may also diversely change and display the application execution screen according to the change in the window size.

FIGS. 7g to 7k illustrate a process of moving a screen according to various embodiments of the present disclosure. As illustrated in FIG. 7g, a user 1 may input a screen movement command 770 on a third window 723. The screen movement command 770 may be a leftward drag. However, the leftward drag is merely illustrative. When the screen movement command 770 is input, a controller (not illustrated) may move and display the screen displayed on the third window 723 in response to the screen movement command 770. As illustrated in FIG. 7h, the controller (not illustrated) may display a screen 780 moved leftwards on the third window.

Alternatively, as another embodiment, as illustrated in FIG. 7i, the controller (not illustrated) may generate and display a scroll bar 771. The scroll bar 771 may be moved by a user, and a screen may be moved and displayed in correspondence to a movement of the scroll bar 771. For example, as illustrated in FIG. 7j, a user 1 may input a screen movement command that is a leftward drag 772 on the scroll bar 771. As illustrated in FIG. 7k, the controller (not illustrated) may display the screen 780 moved leftward on the third window in response to the input screen movement command. In addition, when a preset time interval passes after the screen is moved, the controller (not illustrated) may not display the scroll bar 771. Meanwhile, the scroll bar 771 displayed at an upper side of the third window and moved leftward and rightward is merely illustrative, and the scroll bar 771 may also be displayed at a left side or right side of the third window, and may be moved upward and downward.

FIGS. 8a to 8c illustrate a process of changing a window size.

Referring to FIG. 8a, a display device 800 displays first to fourth windows 801 to 804 on a touch screen. The third window 803 may execute a gallery application that displays a specific image file. As illustrated in FIGS. 8b and 8c, a user may enlarge the third window 803 by dragging a center button.

As illustrated in FIG. 8b, a controller (not illustrated) enlarges and displays an application execution screen such that the application execution screen may be displayed in an entire area of a enlarged third window 813.

Meanwhile, as illustrated in FIG. 8c, if the application execution screen is enlarged in correspondence to a window size when a third window 823 is further enlarged, there may be a problem in resolution. Accordingly, the display device may enlarge and display only the third window 823 without further enlarging the application execution screen. Namely, the display device may compare the size of the application execution screen with a preset threshold value, and may control such that the application execution screen is not enlarged in excess of the threshold value.

FIGS. 9a to 9c illustrate a process of reducing a window size according to another embodiment of the present disclosure.

Referring to FIG. 9a, a display device 900 displays first to fourth windows 901 to 904 on a touch screen. The third window 903 may execute a clock application that displays time. As illustrated in FIGS. 9b and 9c, a user may reduce the third window 903 by dragging a center button.

As illustrated in FIG. 9b, a controller (not illustrated) reduces and displays an application execution screen such that the application execution screen may be displayed in an entire area of a reduced third window 913.

However, when a third window 923 is reduced as illustrated in FIG. 9c, it is difficult for a user to recognize time through an analog clock. Accordingly, the controller (not illustrated) may display another application execution screen instead of the existing application execution screen, when the third window 923 is reduced in size smaller than a preset threshold value. It may be identified in the embodiment of FIG. 9c that the execution screen of the application executed on the third window 923 has been replaced from the analog clock to a digital clock.

FIGS. 10a to 10c illustrate a process of enlarging a window size according to another embodiment of the present disclosure.

Referring to FIG. 10a, a display device 1000 displays first to fourth windows 1001 to 1004 on a touch screen. The third window 1003 may execute a gallery application that displays images. As illustrated in FIGS. 10b and 10c, a user may enlarge the third window 1003 by dragging a center button.

As illustrated in FIG. 10b, a controller (not illustrated) enlarges and displays an application execution screen such that the application execution screen may be displayed in an entire area of an enlarged third window 1013.

However, when a third window 1023 is enlarged as illustrated in FIG. 10c so that a size of the third window 1023 exceeds a preset threshold value, the display device may display another application execution screen instead of the existing execution screen. As noted, in the embodiment of FIG. 10c, an image screen of the gallery application has been replaced with a screen that displays folders into which applications are grouped.

FIGS. 11a and 11b illustrate a process of displaying an application execution screen depending on a change in a window size according to an embodiment of the present disclosure.

Referring to FIG. 11a, a display device 1100 may display a plurality of windows 1101, 1102, 1103, and 1104 such as, for example, first to fourth areas. A user may input a command to change a size of the plurality of windows 1101, 1102, 1103, and 1104 through a drag gesture on a center button or a boundary line. As illustrated in FIG. 11b, depending on the change in the window size according to the embodiment of the present disclosure, application execution screens may be displayed in respective windows 1111, 1112, 1113, and 1114 the size of which is changed through scaling by which a horizontal to vertical ratio prior to the change is maintained.

FIG. 12 is a flowchart describing a method of controlling a display device according to another embodiment of the present disclosure.

The display device may set a plurality of window display spaces such as, for example, the first to fourth areas of FIG. 2a to display a plurality of windows, in step S1101. The display device may set, for example, at least one boundary line, and thereby may set the plurality of window display spaces.

When the plurality of window display spaces are set, the display device may receive an input of a window size change command such as a drag gesture on a boundary line or a center button, in step S1103.

The display device may determine in step S1105 whether a window size is smaller or larger than a threshold value. When the window size is not smaller or larger than the threshold value (S1105-N), the display device resizes and displays the window, and at the same time, resizes and displays the application execution screen in correspondence to the window size. When the window size is smaller or larger than the threshold value (S1105-Y), the display device may display another screen instead of the application execution screen, in step S1107.
