[ This may be useful for editing an image displayed on the display unit 151.

One function of the terminal may be executed in response to a case where the display unit 151 (touch screen) and the touch pad 135 are touched together within a predetermined time range. In the case of being touched together, there may be a case where the user clamps the terminal body using the thumb and index finger. For example, the function may include activation or deactivation of the display unit 151 or the touch pad 135.

The proximity sensor 141 described with reference to FIG. 1 will be described in more detail with reference to FIG. 4.

4 is a conceptual diagram illustrating a proximity depth of a proximity sensor.

As shown in FIG. 4, when a pointer such as a user's finger or pen approaches the touch screen, the proximity sensor 141 disposed in or near the touch screen detects this and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to a distance between the proximity touched pointer and the touch screen (hereinafter, referred to as “proximity depth”).

In FIG. 4, for example, a cross section of a touch screen on which three proximity sensors capable of sensing three proximity depths is disposed is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d ₀ ), it is recognized as a touch touch. When the pointer is positioned below the distance d ₁ on the touch screen, the pointer is recognized as a proximity touch of a first proximity depth. When the pointer is spaced apart from the distance d ₁ or more and less than d ₂ on the touch screen, the pointer is recognized as a proximity touch of a second proximity depth. When the pointer is spaced apart from the distance d ₂ or more and less than d ₃ on the touch screen, the pointer is recognized as a proximity touch of a third proximity depth. When the pointer is positioned at a distance of more than d ₃ from the touch screen, the proximity touch is recognized as released.

Accordingly, the controller 180 may recognize the proximity touch as various input signals according to the proximity depth and the proximity position of the pointer, and perform various operation control according to the various input signals.

FIG. 5 is a conceptual diagram illustrating a control method for a touch operation when a pair of display units 155 and 156 overlap.

The terminal disclosed in this drawing is a folder-type terminal in which a folder unit is foldable with respect to a main body. The first display unit 155 mounted on the folder unit may be a light transmissive type or a transparent type such as a TOLED, but the second display unit 156 mounted on the main body may have a form such that light does not penetrate like an LCD. The first and second display units 155 and 156 may be configured as touch screens capable of touch input, respectively.

For example, when a touch (contact touch or proximity touch) with respect to the first display unit (for example, the TOLED) 155 is detected, the controller 180 determines the type of touch. And at least one image selected from the image list displayed on the TOLED 155 according to the touch time.

Hereinafter, the touch, long touch, and the like may be controlled in a manner in which information displayed on the second display unit (for example, LCD) 156 is controlled when the TOLED 155 is exposed to the outside in an overlapped form. The following description will be based on input methods divided into long touch and drag.

In the overlapped state (mobile terminal is closed), the TOLED 155 is disposed to overlap the lower side of the LCD 156. In this state, when a touch different from a touch for controlling the image displayed on the TOLED 155 is detected, for example, a long touch (for example, a touch lasting more than 2 seconds to 3 seconds), the controller 180 ) Causes at least one image of the image list displayed on the LCD 156 to be selected according to the sensed touch input. The result of the execution of the selected image is displayed on the TOLED 155.

The long touch can also be used to selectively move a desired one of the objects displayed on the LCD 156 to the TOLED 155 (without its execution operation). That is, the user may select one area of the TOLED 155 corresponding to the specific object of the LCD 156. In the long touch, the controller 180 moves the object to the TOLED 155 for display. Meanwhile, the object displayed on the TOLED 155 may also be transferred to the LCD 156 according to a predetermined touch input, for example, flicking, swirling, or the like, on the TOLED 155. In this figure, the menu No. 2 displayed on the LCD 156 is moved to the TOLED 155 and illustrated.

If another input, for example, a drag, is additionally detected along with the long touch, the controller 180 is a function related to the image selected by the long touch, for example, a preview screen for the image is displayed on the TOLED 155. Can be displayed on. In this figure, the case where the preview (male photograph) with respect to the 2nd menu (image file) is performed is illustrated.

When the preview screen is output and the drag is made to the TOLED 155 to another image while maintaining the long touch, the controller 180 controls the selection cursor (or selection bar) of the LCD 156. The selected cursor is displayed on the preview screen (woman photo). After that, when the touch (long touch and drag) is finished, the controller 180 displays the first image selected by the long touch.

The touch operation (long touch and drag) may be performed when a slide (a close touch operation corresponding to the drag) is detected together with a long proximity touch (a close touch lasting at least 2 seconds to 3 seconds) for the TOLED 155. The same applies to.

If a touch operation other than those mentioned above is detected, the controller 180 may operate in the same manner as a general touch control method.

The control method for the touch operation in the overlapped form may be applied to a terminal having a single display. In addition, the present invention can be applied to a terminal different from a folder type having a dual display.

6A and 6B are views referred to for describing a proximity touch recognition region in which a proximity signal is detected and a haptic region in which a haptic effect occurs.

FIG. 6A illustrates an object such as an icon or a menu item in a circle for convenience of description. As shown in (a) of FIG. 6A, an area where an object is displayed on the display unit 151 may be divided into a first area A in the center and a second area B surrounding the area. The first area A and the second area B may be configured to generate a tactile effect having different intensities or patterns. For example, the first vibration may be output when the second region B is touched, and the second vibration may be output when the first region A is touched.

If it is necessary to simultaneously set the proximity touch recognition area and the haptic area in the area where the object is displayed, the haptic area where the haptic effect occurs and the proximity touch recognition area where the proximity signal is detected Can be set differently. That is, the haptic area may be set narrower than the proximity touch recognition area, or the haptic area may be set wider than the proximity touch recognition area. For example, in (a) of FIG. 6A, an area including the first area A and the second area B may be set as a proximity touch recognition area, and the first area A may be set as a haptic area.

As shown in Fig. 6A (b), the area in which the object is displayed is divided into three areas A, B, and C, or as shown in Fig. 6A (c), N (N> 4). It can also be divided into three areas. Each divided area may be configured to generate a tactile effect having different intensities or patterns. Even when the area in which one object is displayed is divided into three or more areas, the haptic area and the proximity touch recognition area may be set differently according to the use environment.

The display unit 151 may be configured such that the size of the proximity touch recognition area varies depending on the depth of proximity. That is, as shown in (a) of FIG. 6B, the corresponding proximity touch recognition area is gradually reduced to 'C', 'B', and 'A' according to the proximity depth to the display unit 151, Alternatively, the corresponding proximity touch recognition region may be gradually increased according to the depth of proximity to the display unit 151. Even in this case, the haptic region may be set to a constant size regardless of the depth of proximity to the display unit 151 as in the 'H' region illustrated in FIG. 6B.

 In the case of dividing the region where the object is displayed for setting the haptic region or the proximity touch recognition region, in addition to the concentric division as shown in FIG. 6A, the division in the horizontal or vertical direction, the radial division, and a combination thereof Various methods, such as division, can be used.

For convenience of description, it is assumed that the mobile terminal mentioned below includes at least one of the components shown in FIG. 1. In addition, it is assumed that the mobile terminal mentioned below includes a touch screen. In addition, the touch mentioned below may include both the above-described contact touch and proximity touch.

Hereinafter, the background screen display control method of the mobile terminal according to the present invention will be described with reference to FIG. 7. 7 is a flowchart illustrating a method for controlling a background screen display of a mobile terminal according to an embodiment of the present invention.

As illustrated in FIG. 7, the mobile terminal 100 may control at least two of the plurality of areas including an area for storing available function icons (hereinafter, referred to as a storage area) under the control of the controller 180. An image including an area (hereinafter, 'multiple area image') is displayed on the touch screen (S710).

Here, the storage area may mean an area in which all function icons stored and managed in the mobile terminal 100 are displayed on the screen.

Also, in areas except the storage area, at least one icon among function icons stored in the storage area is allocated according to the user's selection or the controller 180's selection, and the function icons allocated on the screen are displayed. It may mean an area that becomes.

Therefore, in the areas included in the multi-region image displayed in the display operation S710, a function icon corresponding to each may be displayed. In addition, the plurality of regions included in the plurality of region images may be displayed separately.

Here, the function icon is an icon assigned to each of functions (eg, a schedule management function, a picture viewing function, a video viewing function, a messenger function, a radio listening function, etc.) that can be executed in the mobile terminal 100. When a function icon is selected, a function corresponding to a specific function icon may be executed.

In addition, the function icon may be displayed in the form of a widget. More specifically, the function icon that can be displayed in the form of a widget among the function icons may be displayed in the form of a widget. Here, the widget refers to a key area for receiving a signal related to execution of a corresponding function directly from a user and an icon displaying brief contents of the corresponding function. Accordingly, the user may execute or control the corresponding function using the key area displayed in the widget without inputting a separate operation for executing the corresponding function with respect to the function icon displayed in the form of a widget.

In the display step S710, a multi-region image may be displayed as a background screen. Alternatively, the display step S710 may be performed as one of the background screen setting processes as a menu item corresponding to the background screen setting is selected by the user.

For example, as illustrated in FIG. 8, the multi-region image may include a first region 810, a second region 820, and a storage region 830. In the storage area 830, function icons stored in the mobile terminal 100 are displayed, and function icons assigned to the first and second areas are displayed in the first and second areas. In particular, function icons that can be displayed in the form of a widget in each region may be displayed in the form of a widget.

Returning to FIG. 7, the mobile terminal 100 allocates at least one function icon to each of the plurality of areas (excluding the storage area) under the control of the controller 180 (S720).

For convenience of description, it is assumed that the plurality of areas includes the first and second areas.

First, a process of assigning a function icon using touch drag from a storage area to a first or second area will be described. In this regard, this may be described with reference to FIGS. 9A and 9B.

If the touch screen includes the storage area and the first area (or the second area) in the multi-region image displayed in the display step S710, the function icon displayed in the storage area corresponds to the touch operation input from the user. Any function icon among these may be touch-draged to the first area (or the second area).

Therefore, in the assigning step S720, the controller 180 may allocate the touch dragged arbitrary function icon to the first area (or the second area).

For example, as shown in FIGS. 9A and 9B, as the function icon 831 displayed in the storage area 830 is touch-draged to the first area 810, the function icon 831 is changed to the first area ( 810 may be assigned.

Next, a process of assigning a function icon using touch drag between the first area and the second area will be described. In this regard, this may be described with reference to FIGS. 10A and 10B.

When the first area and the second area are included in the multi-region image displayed in the display step S710, the touch screen is displayed in the first area (or the second area) to correspond to a touch operation input from the user. Any function icon among the function icons may be touch-draged to the second area (or the first area).

Accordingly, in the assigning step S720, the controller 180 may allocate the touch dragged arbitrary function icon to the second area (or the second area).

For example, as shown in FIGS. 10A and 10B, as the function icon 815 displayed in the first area 810 is touch-draged to the second area 820, the function icon 815 is moved to the second area. 820 may be assigned.

Next, a process of deassigning a function icon using touch drag from the first or second area to the storage area will be described. In this regard, this may be described with reference to FIGS. 11A and 11B.

If the touch screen includes the storage area and the first area (or the second area) in the multi-region image displayed in the display step S710, the touch screen may correspond to the touch operation input from the user, or the first area (or the second area). Touch any function icon among the function icons displayed in the area) to the storage area.

Therefore, in the assigning step S720, the controller 180 may release the touch dragged arbitrary function icon from the first region (or the second region).

For example, as shown in FIGS. 11A and 11B, as the function icon 815 displayed in the first area 810 is touch-draged to the storage area 830, the function icon 815 may be changed to the first area ( Allocation to 810 may be released.

In addition, the assigning step (S720) may be performed by receiving a user selection operation through a screen for allocating a function icon for each region as a menu item corresponding to a function icon allocation for each region is selected by the user. .

In addition, in the assigning step S720, the controller 180 may designate an application for each region according to a user's selection and allocate at least one function icon corresponding to the designated application to the corresponding region.

For example, when a broadcast mode related application is assigned to the first area, a function icon (s) corresponding to the broadcast mode related application may be assigned to the first area, and when a camera related application is assigned to the second area. In the second area, function icon (s) corresponding to a camera-related application may be allocated.

When the mobile terminal 100 receives a region selection operation from the user, the mobile terminal 100 selects a specific region from among the plurality of region images displayed in the display step S710 under the control of the controller 180 (S730).

In operation S730, an area touched by the user may be selected from among the plurality of areas included in the multi-region image. Alternatively, when a number is assigned to each of the plurality of areas included in the plurality of area images in the selecting step S730, an area to which a number selected by the user is assigned may be selected. Alternatively, in the selection step S730, a specific area may be selected among the plurality of areas included in the multi-region image by manipulating the direction key.

Alternatively, in the selecting step S730, as a menu item corresponding to a background screen setting is executed, an area selected by a user may be selected from among a plurality of areas to which a function icon is assigned.

The mobile terminal 100 displays the first image including at least one function icon assigned to the area selected in the selection step S730 as a background screen under the control of the controller 180. (S740).

The selection step S730 and the display step S740 will be described in detail with reference to FIGS. 12A to 13B.

As shown in FIGS. 12A and 12B, when a user selects a first area 810 among a plurality of area images, the controller 180 may include images including function icons assigned to the first area 810. Can be displayed as the background screen.

Alternatively, as shown in FIGS. 13A and 13B, when the first and second regions 810 and 820 are selected from among the multi-region images, the controller 180 may include the first region 810 and the second region ( The image including the function icons assigned to each of the screens may be displayed as a background screen. In this case, the first area 810 and the second area 820 may be displayed differently.

Returning to FIG. 7, among the function icons included in the image displayed in the display step S740, the function icon displayed in the form of a widget includes a key area for selecting end of display in the form of a widget (hereinafter referred to as “widget end key area”). ') May be included.

When the widget end key area included in the specific function icon is selected, the controller 180 may end the display of the specific function icon in the form of a widget. This does not mean that the specific function icon is deallocated in the corresponding area, but merely means to release the display of the specific function icon as a widget in the corresponding area. Therefore, the controller 180 may display the specific function icon as a general function icon instead of a widget form or stop displaying the specific function icon. In this case, a key area (hereinafter, referred to as a "return key area") for returning the display in the form of a widget is provided in one area of the screen, and when a return key area is selected by the user, a specific function icon is set again in the widget shape. Can be displayed as

For example, as illustrated in FIGS. 14A and 14B, when the widget end key area of the first function icon 811 is selected from among a plurality of function icons displayed in the form of a widget on the background screen, the controller 180 The display may return to the widget form of the first function icon 811 and display the return key area 811-1 for returning the display of the first function icon 811 in the form of a widget to an area of the screen. have. Therefore, when the return key area 811-1 is selected by the user, as illustrated in FIG. 14A, the first function icon 811 may be displayed in the form of a widget.

Although not shown in the drawing, each widget end key region may be selected for at least two function icons among a plurality of function icons displayed in the form of a widget, and each return when the display in the form of a widget is terminated. The key area can be displayed. Thus, the user can individually select the function icon that he wants to display in the form of a widget.

Of course, the function icon that is not displayed in the form of a widget may also include a key area (hereinafter, an 'icon end key area') for selecting the end of display of the function icon. When the icon end key area is selected, the allocation of the corresponding function icon is not released, only the on-screen display is released, and the on-screen display may be returned according to the user's selection.

Of course, the end key region may also be included in the function icon displayed in the form of a widget in the image displayed in the display step 710 and the display step S760 described later.

The mobile terminal 100 receives a touch operation corresponding to a background screen change command through the touch screen (S750). The controller 810 may detect whether a touch operation corresponding to a background screen change command is input.

In general, the input step S750 may be performed in a state in which an image including at least one function icon assigned to a specific area is displayed as a background screen.

For convenience of description, it is assumed that the mobile terminal 100 displays the first image including at least one function icon allocated to the first area as the background screen when the input step S750 is performed.

In addition, in the input operation S750, the touch operation may be input at a predetermined proximity height while the first image is displayed as the background screen by applying the proximity touch.

And, the mobile terminal 100, according to the control of the controller 180, corresponding to the touch operation received in the input step (S750), the second image including a function icon assigned to other areas except the first area Is displayed as a background screen on the touch screen (S760).

The touch operation input in the input step S750 may include a touch pattern for distinguishing an area selection direction, an area selection order, or a specific area designation. Therefore, the background screen displayed in the display step S760 may display an area corresponding to the touch pattern.

Of course, the controller 180 determines whether the touch pattern of the touch operation input in the input step S750 matches the preset touch pattern, and if it matches, selects an area corresponding to the touch pattern of the input touch operation. Can be displayed.

Hereinafter, as shown in FIG. 8, the first area 810 and the second area 820 are disposed in the horizontal direction, and the storage area 830 is a lower end of the first and second areas 810 and 820. It is assumed that the case is arranged in the vertical direction.

Alternatively, when a touch operation in a downward direction is input while the first image is displayed as a background screen (2 in FIG. 15A), the controller 180 may include an image including function icons stored in the storage area 830. (Hereinafter, 'third image') may be displayed as a background screen (see FIGS. 15A and 15C).

Next, the area selection order will be described in detail as follows. For convenience of description, the area selection order is specified in the order of the first area 810, the second area 820, and the storage area 830. The touch operation in the right direction (or the downward direction) may be assumed to be a touch operation for sequentially selecting regions according to the region selection order.

Therefore, when the touch operation in the right direction (or the downward direction) is input while the first image is displayed as the background screen, the controller 180 may display the second image as the background screen. The controller 180 may display the third image as the background screen when the touch operation in the right direction (or the downward direction) is input while the second image is displayed as the background screen.

When the first image is displayed as the background screen and the touch operation in the right direction (or the downward direction) is received twice in succession, the controller 180 may display the third image as the background screen. .

In addition, when the proximity touch is applied, as the height of the proximity becomes short while the first image is displayed as the background screen, the controller 180 may sequentially select the second image and the third image as the background screen.
