The window may be an area including a title bar and a control area for an execution screen of a specific application and an application to be executed. On the execution screen of the application, objects related to the application can be displayed. The object can be formed in various shapes such as text, graphic, icon, button, check box, photograph, video, web, map and the like. When a user touches an object, the object can be performed in an application corresponding to a predetermined function or event. The object may be referred to as a view depending on the operating system. The title bar may include at least one control key for controlling the display of the window. For example, the control key may be a window display minimization button, a window display maximize button, and a window exit button.

The applications are programs independently implemented by the manufacturer of the display device 300 or application developers. Accordingly, one application does not require another application to be executed in advance to be executed. Even if one application is terminated, another application can be continuously executed.

The application is a program implemented independently of each other. Therefore, a multi-function application (or a dual-function application) in which some functions (memo function, message transmission / reception function) provided by another application are added in one application (for example, Application). However, such a multifunctional application is a single new application that has various functions and is different from existing applications. Accordingly, the multi-function application can not provide various functions as in existing applications, and not only provides limited functions, but also has a burden to the user to purchase the new multi-function application separately.

On the other hand, the control unit 110 controls the plurality of windows 311 and 312 to be partially overlapped and displayed. The control unit 110 can set display ranks for the plurality of windows 311 and 312, respectively. For example, the controller 110 may set a first display order for the window 311 and a second display order for the window 312. [ Accordingly, the control unit 110 displays the window 311 having a relatively high display order so as to cover the window 312. Of the areas of the window 312 having the relatively low display rank, portions overlapping the window 311 having a relatively high display rank are not displayed.

The control unit 110 can set the highest display order to the window in which the control event is most recently inputted. For example, when the user touches the window 311, the control unit 110 sets the highest display order to the window 311. [

3B is a conceptual diagram for explaining a framework according to the present invention.

3B, in the framework 270, the activity manager 291, the window manager 292, and the view system 294 may be compatible with the multi-window framework 400. Here, the compatibility with the multi-window framework 400 may be an application program interface (API) call, for example.

The multi-window framework 400 includes a multi-window manager 410 and a multi-window service 420.

The activity manager 291, the window manager 292, and the view system 294 may perform an API (Application Program Interface) call for the multi-window.

The multi-window manager 410 provides the functions of the multi-window service 420 to the user in API form, and the Manager / Service structure can operate based on IPC. The multi-window manager 410 may generate a title bar for each window. The multi-window manager 410 may also retrieve the z-order of each window or determine the z-order order between the windows. In addition, when a specific window is covered with another window, it is also possible to control to display a conversion icon on the title bar that can be switched over to the window displayed.

The multi-window service 420 tracks the lifecycles of applications executed in a multi-window, and manages the states such as size and location of each application.

The called API can manage the size, location, and visibility of each window.

As described above, the framework according to the present invention can be performed by providing an independent multi-window framework and calling an API.

In addition, the application layer 260 may directly call the API from the multi-window manager 410 (404). That is, the user can use the API provided from the multi-window manager 410 even when developing a new application.

As described above, the present invention adopts the multi-window framework 400 and can display two or more applications at the same time.

3C is a screen for explaining the display rank change.

In Fig. 3C, the user 1 touches the window 312. Fig. The control unit 110 sets the highest display order in the window 312 in which the control event is most recently inputted. In addition, the control unit 110 sets a next highest ranking for the window 311 of the existing highest ranking. That is, the control unit 110 decreases the display order of the window 311 by one level.

FIG. 3D is a screen in which a window in which the display rank is changed is displayed.

As shown in FIG. 3D, the window 312, which is the highest display order, can be displayed while covering the window 311. [ The portion of the window 311 having the relatively low display order and the portion overlapping the window 312 having the relatively high display order are not displayed.

3E is a conceptual diagram of a task stack. The task stack can set a high task ranking for applications that have most recently entered control events. For example, in the embodiment of FIG. 3A, the album (ALBUM) application 352 has a higher task ranking than the note application 351. On the other hand, in the embodiment of FIG. 3D, the note application 351 has a higher task ranking than the album application 352. [

3F is a conceptual view of the display stack. Like the task stack, the display stack can be set to a higher priority for the application that has most recently entered control events. For example, in the embodiment of FIG. 3A, the ALBUM application 352 has a higher display rank than the note application 351. On the other hand, in the embodiment of Fig. 3D, the note application 351 has a higher display rank than the album application 352. [

That is, the control unit 110 may set the task stack and the display stack to be the same.

3G is a conceptual diagram of a display stack when a new application is executed.

In Fig. 3G, it is assumed that the A to D applications 371 to 374 are being executed. On the other hand, the user can input the top display command to the A application 371 and the B application 372. [ On the other hand, the user can newly execute the New application 375. [ The control unit 110 preferentially sets the highest display order in the New application 375. [ In addition, the control unit 110 can adjust the display order of the New application 375 to the next higher level of the A and B applications 371 and 372 receiving the highest display command. The control unit 110 adjusts the display order of the New application 375 to be higher than that of the other applications 373 and 374. [ As described above, the control unit 110 can control the applications A and B that received the top-level display command to have the highest display order even if the last selected new application is executed by the user. The top position of the display stack may be the most recently executed application or the most recently selected topmost display application.

4A to 4D are conceptual diagrams for explaining the operation of the display device according to the embodiment of the present invention.

4A, the display device 400 may display the first windows 411 and 412 and the second windows 421 and 422 on the touch screen. The first windows 411 and 412 may include a first title bar 411 and an execution screen 412 of the first application. The second windows 421 and 422 may include a second title bar 421 and an execution screen 422 of the second application.

On the other hand, the user can move the second windows 421 and 422 in the left direction. The user can move the second windows 421 and 422 by, for example, designating the second title bar 421 and then dragging it to the left. However, it is understood that changing the position of the window by performing dragging after designating the title bar is merely exemplary, and those skilled in the art can easily change the position of the window in various other ways.

FIG. 4B is a conceptual diagram for explaining a case where the positions of the second windows 421 and 422 are changed and displayed while covering the first windows 411 and 412. FIG. 4B, the user may move the positions of the second windows 421 and 422 to the left until the first windows 411 and 412 are covered. In such a case, the task ranking of the second windows 421 and 422 is set higher than the task ranking of the first windows 411 and 412. In addition, the display order of the second windows 421 and 422 is set higher than the display order of the first windows 411 and 412. Accordingly, the second windows 421 and 422 can be displayed while covering the first windows 411 and 412. That is, the first windows 411 and 412 are covered by the second windows 421 and 422.

The control unit (not shown) of the display device 400 can confirm that the second windows 421 and 422 cover and cover the first windows 411 and 412. For example, the control unit (not shown) may compare the pixel coordinate range of the area where the second windows 421 and 422 are displayed and the pixel coordinate range of the area where the first windows 411 and 412 are displayed. The control unit (not shown) can determine whether the pixel coordinate range of the area where the second windows 421 and 422 are displayed and the pixel coordinate range of the area where the first windows 411 and 412 are displayed overlap each other. If it is determined that the pixel coordinate range of the area in which the second windows 421 and 422 are displayed and the pixel coordinate range of the area in which the first windows 411 and 412 are displayed overlap each other, Order windows 421 and 422 can be compared. When the z-order of the second windows 421 and 422 is higher than the z-order of the first windows 411 and 412, the control unit (not shown) displays the second windows 421 and 422 while covering the first windows 411 and 412 .

If it is determined that the second windows 421 and 422 are to be displayed while covering the first windows 411 and 412, the control unit (not shown) may display the first window change icon 430 on the second title bar 421 . Here, the first window switching icon 430 may be an icon for switching the first windows 411 and 412 to be displayed at the top when designated. It is to be appreciated that the display of the first window switching icon 430 on the second title bar 421 is merely exemplary and that the display position of the first window switching icon 430 is not limited There will be.

On the other hand, the user can designate the first window switching icon 430 to view the first windows 411 and 412.

4D is a conceptual diagram when the first window switching icon is designated. 4D, when the first window switching icon is designated, the control unit (not shown) may display the first windows 411 and 412 on the second windows 421 and 422. [ More specifically, the control unit (not shown) can control the task ranking and the display order of the first windows 411 and 412 to the highest level, thereby controlling the first windows 411 and 412 to be displayed at the top . According to the above description, the user can change the first window 421, 422 without moving the second window 421, 422 to view the first window 411, 412 when the first window 411, 412 is covered by the second window 421, The first windows 411 and 412 can be easily seen.

4A to 4D illustrate that the above-described bar is applied to two windows, but this is merely an example, and a person skilled in the art can easily understand that a window can be applied to cover two or more windows I can understand it. This will be described later in more detail.

5 is a flowchart illustrating a method of controlling a display device according to an embodiment of the present invention. As shown in FIG. 5, the first window and the second window may be displayed on the touch screen, respectively (S501).

The control unit can determine whether the first window displayed on the touch screen covers the second window and displays the second window (S503). For example, the control unit compares the pixel coordinates of the area in which the first window and the second window are displayed, and determines whether pixel coordinates overlap. When the pixel coordinates of the area in which the first window and the second window are displayed overlap, the controller can compare the z-order of the first window and the second window. If the z-order of the first window is larger than the z-order of the second window, the control unit may determine that the first window covers the second window.

If the first window is not displayed while covering the second window (S503-N), the control unit displays the first window and the second window on the touch screen at step S501. If the first window is not displayed while covering the second window (S503-Y), the control unit can display the icon for switching to the second window (S505). For example, the control unit can display the second window switching icon on the title bar of the first window, but the display position of the second window switching icon is not limited.

On the other hand, the creation of the conversion icon can be performed by the window manager of the framework. As described above, the window manager can generate the title bar of each window, and can also search the z-order of each window. The window manager may determine the z-order order between windows. In addition, when a specific window is covered with another window, a conversion icon that can be switched to a window that is covered and displayed is displayed on the title bar.

Here, the control unit may control the second window switching icon to be displayed when the first window displays the second window completely covering the second window. Alternatively, the control unit may control the second window switching icon to be displayed when the first window is displayed while covering a part of the second window. For example, the control unit may control the second window switching icon to be displayed from the time point when the first window covers the second window. Alternatively, the control unit may control the second window switching icon to be displayed from the time point when the first window covers the predetermined ratio or more of the second window. There is no limitation on the time point at which the second window switching icon is displayed and it will be easily understood by those skilled in the art that the display time point of the second window switching icon can be changed to maximize user convenience.

The control unit determines whether a second window switching icon is designated (S507). If it is not determined that the second window change icon is designated (S507-N), the control unit maintains the second window change icon display (S505). If it is determined that the second window switching icon is designated (S507-Y), the control unit displays the second window at the top (S509). More specifically, the control unit switches the task ranking and display rank of the second window to the highest level. Accordingly, the control unit controls the second window to be displayed while covering the first window.

6 is a detailed flowchart of step S503 of FIG. 5 whether the first window according to an exemplary embodiment of the present invention is displayed while covering the second window.

The controller confirms the pixel coordinates of the first window display area displayed on the touch screen (S601). The controller confirms the pixel coordinates of the second window display area displayed on the touch screen (S603).

The controller may determine whether the pixel coordinates of the first window display area and the pixel coordinates of the second window display area overlap (S605). If it is determined that the pixel coordinates of the first window display area and the pixel coordinates of the second window display area do not overlap (S605-N), the controller may determine that the first window does not display while covering the second window S607). If it is determined that the pixel coordinates of the first window display area and the pixel coordinates of the second window display area overlap (S605-Y), the controller compares the z-order of each of the first window and the second window (S609). If it is determined that the z-order of the first window is larger than the z-order of the second window (S609-Y), the controller may determine that the first window is displayed while covering the second window (S611) . If it is determined that the z-order of the first window is smaller than the z-order of the second window (S609-N), the controller may determine that the second window is displayed while covering the first window (S613) .
