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

In response to the display unit 151 (touch screen) and the touch pad 135 being touched together within a predetermined time range, one function of the terminal may be executed. When touched together, the user may clamp 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 can also detect less than three or more than four proximity depths.

In detail, when the pointer is completely in contact with the touch screen (d0), the pointer is recognized as a touch. When the pointer is positioned below the distance d1 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 d1 or more and less than d2 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 d2 distance by more than d3 distance on the touch screen, it is recognized as a proximity touch of a third proximity depth. When the pointer is located at a distance greater than or equal to d3 on 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 in which light does not transmit, such as 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 or the TOLED 155 is detected, the controller 180 may determine a touch type and a touch time. Accordingly, at least one image of the image list displayed on the TOLED 155 may be selected or run.

Hereinafter, touch, long touch, long touch, and drag (drag) are applied to a method in which information displayed on another display unit or LCD 156 is controlled when a touch is applied to the TOLED 155 exposed to the outside in an overlapped form. The description is based on the input method separated by).

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. The object displayed on the TOLED 155 may also be displayed on the LCD 156 according to a predetermined touch input for the TOLED 155, for example, flicking or swirling. 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 (movement of the proximity touch corresponding to the drag) is detected together with the long proximity touch (the proximity 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.

When a mobile terminal having a transparent display module according to the present invention is classified according to the structure of the display module, the mobile terminal may be divided into a terminal having a dual display module and a terminal having a single display.

The single display terminal refers to a terminal composed of one transparent display module or a terminal composed of one display module by overlapping the transparent display with a non-transparent display. The dual display terminal refers to a terminal in which the transparent display module and the non-transparent display module are separately configured.

The dual display terminal and the single display terminal may each be a folder type, a flip type, a slide type, a bar type, a rotation type (swivel, swing) type, or It can be applied to watch type.

The transparent display module described below may be touched on both sides.

Touch pads may be attached to both sides of the transparent display module for the two-sided touch. For convenience of description, the side facing both sides of the transparent display facing the user is referred to as the front side and the opposite side is referred to as the rear side.

6 is an exemplary diagram for explaining an object selection and execution method of a mobile terminal according to the present invention. In Figure 6 (a) is an exemplary view showing the front of the transparent display module, (b) is an exemplary view showing the back of the transparent display module.

The transparent display module displays specific objects 410 on the execution screen according to a menu executed in the mobile terminal. For example, the specific objects 410 refer to objects that can be selected and executed or edited by a user, such as a menu icon, a menu item, or a content item. Thus, the objects may be in the form of images or in the form of text.

In order to select or execute the specific object by a touch method, a touch time or a touch count is generally used. For example, if one of the objects is touched briefly, a selection operation is performed, and if the touch is released, an execution operation of the selected object is performed. Alternatively, when one of the objects is briefly touched once, the selection operation is performed, and when the user touches twice briefly, the execution of the selected object is performed.

However, in the method of selecting or executing a specific object using the touch method as described above, an object that the user simply wants to select may be executed. That is, a touch error may occur according to a slight difference in the touch method of the user, and thus an operation not desired by the user may be executed.

However, when the mobile terminal of the present invention selects and executes an object by a touch method, the touch error as described above is distinguished by distinguishing a simple selection operation and an execution operation of a specific object displayed on the screen according to the touch input side of the two surfaces. Can be prevented. That is, when the specific object displayed on the transparent display module is touched from the front side, the preset first operation is executed, and when the same object is touched from the back side, the preset second operation is executed.

The first and second operations may vary according to the type of the selected object.

In addition, the first operation and the second operation may also vary according to the specific menu executed. For example, if the displayed object is a multimedia file (eg, still image, video, music, etc.), when the user touches the multimedia file from the front, the controller 180 immediately executes (plays) the multimedia file. When the user touches the multimedia file from the back side, the controller 180 may simply display information (eg, preview screen, preview, additional information, etc.) about the multimedia file.

In this case, an operation of immediately executing the multimedia file becomes a first operation, and an operation of displaying information about the multimedia file becomes a second operation. As described above, a touch error can be prevented by distinguishing an operation performed according to a touch input surface of both surfaces of the display module.

7 is a flowchart illustrating an object selection and execution method of a mobile terminal according to the present invention.

According to a preset configuration option (not shown), the controller 180 may selectively activate touch pads attached to both sides of the transparent display module. That is, only one of the double-sided touch pads may be activated or both of the double-sided touch pads may be activated.

Hereinafter, it is assumed that both touch pads of both sides are activated (S101).

When the user executes a specific menu, the controller 180 displays various submenu items or content items on the execution screen of the specific menu. In the following description, the sub-menu items or content items are referred to as objects, respectively. That is, the controller 180 displays objects related to the specific menu in operation S102.

When any one of the displayed objects is touched by the user (S103), the controller 180 detects which side of the transparent display module has been touched (S104). If it is touched through the first surface (for example, the front surface) according to the detection result (S105), the controller 180 executes a preset first operation (S106), and if it is touched through the second surface (for example, the rear surface). The set second operation is executed (S107). In this case, the first and second operations may vary depending on the executed menu or the type of the selected object.

Hereinafter, the first operation and the second operation will be described through various embodiments.

In other words, in the embodiment of FIG. 9, the preview screen of the thumbnail item is displayed when the rear touch is performed. In the embodiment of FIG. 10, additional information of the thumbnail item is displayed when the rear touch is performed. That is, even if the same menu or object is touched on the same surface, the third operation or the fourth operation may be executed according to a preset configuration option (not shown).

11 is a third exemplary view for explaining a method of selecting and executing an object of a mobile terminal according to the present invention. In FIG. 11, (a) is an exemplary view showing a scheduler (or schedule) execution screen displayed on the front surface, and (b) is an exemplary view showing a front screen when a specific object (eg, date) is touched on the front surface. , (c) is an exemplary view showing a front screen when the same specific object (eg, date) is touched from the back side.

If a specific object (for example, date) among the objects displayed in FIG. 11 (a) is touched from the front, as shown in (b), the controller 180 may control the specific object (for example, date). Enter the schedule editing mode. If a schedule is already set on the specific date, the schedule content is displayed on the full screen.

When the specific object is touched from the rear side, as shown in (c), the controller 180 displays the schedule set on the specific object (eg, a date) on the preview screen 440. When the touch is released, as shown in (d), the controller 180 immediately displays the scheduler execution screen again.

In the above embodiment, the first operation executed when the specific object is touched from the front is an operation of entering a schedule editing mode of a specific date, and the second operation is an operation of displaying a preview screen of the schedule set on the specific date.

12 is a fourth exemplary view for explaining an object selection and execution method of a mobile terminal according to the present invention. In FIG. 12, (a) is an exemplary diagram showing a multimedia file list screen displayed on the front surface, and (b) is an exemplary diagram showing the front screen when a specific object (for example, a multimedia file) is touched from the front. And (c) is an exemplary view showing a screen displayed in front when the same specific object (for example, a multimedia file) is touched from the rear side.

If a specific object (eg, a multimedia file) 450 among the objects displayed in FIG. 12A is touched from the front, as shown in (b), the controller 180 controls the specific object (eg, Display the playback screen for the multimedia file). The playback information screen includes a plurality of control buttons (eg, stop, go back, go forward, volume control, file loading, etc.) 451.

When the specific object is touched from the rear side, as shown in (c), the controller 180 displays a preview playback screen 452 of the specific object (eg, a multimedia file). When the preview playback screen is output, music is output when the multimedia file is a music file, and video and sound are output when the multimedia file is a video file. In this case, the preview playback screen 452 may simply display a status bar indicating a playback state without including a control button. When the touch on the rear surface is released, as shown in (d), the controller 180 immediately displays the multimedia file list screen again.

In the above embodiment, the first operation executed when the specific object is touched from the front side is an operation of displaying a playback screen including a control button for controlling the playback operation together with the playback of the multimedia file. View This operation displays the playback screen.

FIG. 13 is an exemplary diagram for describing another operation performed according to the method for touching an object in the embodiment of FIG. 12.

If a specific object (eg, multimedia file) 450 of the objects (eg, multimedia files) displayed in FIG. 13A is touched on the front surface of both sides of the transparent display module, as shown in (b) The controller 180 displays a play screen for the specific object (eg, a multimedia file). The reproduction information screen includes a plurality of control buttons.

When the specific object is touched from the rear side, as shown in (c), the controller 180 may include additional information related to the specific object (eg, a multimedia file) (eg, album information including a multimedia file, a singer). Information, actor information, author information, composer information, etc.) 453. When the rear touch is released, as shown in (d), the controller 180 immediately displays the multimedia file list screen again.

In other words, in the embodiment of FIG. 12, the preview playback screen is displayed when the rear touch is performed. In the embodiment of FIG. 13, the additional information of the multimedia file is displayed when the rear touch is performed. That is, even if the same object is touched on the same surface, different operations may be executed according to a preset environment setting option.

14 is a fifth exemplary view for explaining an object selection and execution method of a mobile terminal according to the present invention. In FIG. 14, (a) is an exemplary view showing a short message (SMS) list displayed on the front, and (b) is a screen shown on the front when a specific object (for example, a short message item) is touched from the front. (C) is an exemplary view showing the front screen when the same specific object (eg, a short message item) is touched from the rear side.

If a specific object (for example, a short message item) 460 among the objects displayed in FIG. 14A is touched from the front, as shown in (b), the controller 180 controls the specific object (eg : Enters the edit mode for the short message item). In the short message editing mode, the user can edit the message content.

When the specific object is touched from the rear side, as shown in (c), the controller 180 displays the contents of the specific object (eg, a short message item) 460 on the preview screen 461. . The user can immediately check the message contents through the preview screen. In other words, there is no need to enter multiple buttons to change modes. When the touch of the rear side is released, as shown in (d), the controller 180 immediately displays the short message list screen again.

In the above embodiment, the first operation executed when the specific object is touched from the front is to enter an edit mode for editing the content of the specific short message item, and the second operation is to preview the content of the specific short message. This operation displays the screen.

However, even if the same menu or object is touched on the same surface, the first operation and the third operation may be executed according to a preset configuration option (not shown). That is, although not illustrated in the drawing, when the specific object (eg, a short message item) is touched from the rear side, the controller 180 may provide additional information related to the specific object (eg, a short message item) (eg, caller information, Sender, number of messages sent / received, message items, etc.) can be displayed.

As described above, a method of executing different operations according to the touch surface of a specific object may be applied to an operation of outputting information during a call. For example, although not illustrated in the drawing, when a phone book list or a specific party in a call is touched from the back side, the call history with the other party (eg, call information, message transmission / reception information, etc.) or additional information related to the other party (eg, Group, memo, picture, etc.), and when the specific counterpart is touched from the front, a call or a message can be directly transmitted.

15 is a sixth exemplary view for explaining a method of selecting and executing an object using a touch in a mobile terminal according to the present invention. The method of executing different operations according to the surface on which the specific object is touched on both sides of the display module may be applied to the scrolling operation of the screen.

For example, if a user touches and drags the scroll bar from the front, the screen at the position where the scroll bar is moved is maintained even if the touch is released. However, when the user touches and drags the scroll bar from the rear side, the user may release the touch to return to the position before the scroll bar is dragged. That is, when simply previewing a screen of another position, the user may move the scroll bar to a desired position by touching it from the rear side, and when the touch of the scroll bar is released, the user may return to the original screen before moving the scroll bar.

The scroll function is a function for displaying the remaining parts that are not displayed on the screen by moving the entire contents already displayed on the screen up or down or left and right when the amount of specific information (eg, document, photo, web page, etc.) exceeds one screen. In addition, when specific information items exceed the number that can be displayed on one screen, the items are moved up and down or left and right to display the remaining information items that are not displayed on the screen.

In order to scroll the specific information in a desired direction, it is common to touch the scroll bar and drag it in a desired direction. However, in certain cases, the user may scroll by touching one of the information items and dragging it in the desired direction. However, in a touch input method in which a specific object is selected and executed by touching one surface of the display module as in the related art, when an arbitrary information item is selected for scrolling, an error that the information item is executed (or played) occurs. May occur. For example, when the information item is touched or double touched above a predetermined pressure, an error may occur that the information item is executed (or reproduced).

However, according to the present invention, the method of classifying the selection operation or the execution operation of the object according to the touched surface of the object may prevent a touch error that may occur in the conventional touch input method.

That is, as shown in (a) of FIG. 15, when any object (for example, an information item) 470 displayed on the transparent display module is touched from the front, as shown in (b), the controller ( 180 executes (or plays) the object 470. In addition, as shown in (c), when the same object 470 is touched from the rear side, the controller 180 is not executed even if the object 470 is selected, so that the user touches the object. When dragging in an arbitrary direction (eg, left direction), the objects may be scrolled in the dragged direction as shown in (d).

The information items that may be the scroll object correspond to a text message list, a call list, and a multimedia file list (eg, music, photo, video, wallpaper, theme, phone number, etc.). Meanwhile, when any one of the scrolled information items is selected from the front side, the information item can be immediately executed. For example, when a multimedia file is selected, playback is performed immediately, and when a new wallpaper or menu mode is selected, the background or menu mode can be changed immediately.

16 is a seventh exemplary view for explaining a method of selecting and executing an object using a touch in a mobile terminal according to the present invention.

In FIG. 16, (a) is an exemplary diagram showing a subway map displayed on the front surface, and when a specific object (for example, subway station) 480 is touched from the rear in the route map shown in (a), it is shown in (b). As described above, the controller 180 enlarges a predetermined area around the specific object (eg, a subway station) and displays the preview screen. Then, when the touch is released, as shown in (c), the controller 180 immediately displays the subway map before it is enlarged again.

In the case (b), when the user touches the rear surface and drags to another point, the enlarged and displayed point may be moved accordingly. In addition, the user may select a plurality of specific objects (eg, a subway station) in the route map for quick route search. In order to select the specific object, the user may touch the front surface. The specific object may be selected from the entire subway map shown in (a) or the enlarged subway map shown in (b).

17 is an eighth exemplary view for explaining a method of selecting and executing an object using a touch in a mobile terminal according to the present invention. As described above, the operation of enlarging and displaying a specific object according to the touched surface may be applied to a web browser screen or an image screen.

In FIG. 17, (a) is an exemplary view showing a web browser (or a swap browser) screen displayed on the front side, in which a specific object (or a specific point) 490 is touched from the back in the web browser screen shown in (a). As shown in (b), the controller 180 displays a preview screen enlarged at a preset magnification centering on the specific object (or a specific point) 490. When the touch is released, as shown in (c), the controller 180 immediately displays a web browser screen before being enlarged again.

Although not shown, when a specific point of the still image is touched from the rear side, a still image enlarged around the touch point may be displayed.

As described above, each operation executed according to a surface on which a specific object is touched may be preset through an environment setting option (not shown), and is not limited to the operations described in the above embodiments.

In the above, the operation of directly selecting or executing the same specific object according to the touched surface has been described. For example, the operations of previewing, previewing, and enlarging information related to the object, and playing the object, entering a submenu of the object, or editing the contents of the object have been described.

Hereinafter, a multitasking method of additionally executing separate menus (or functions) according to the touch input side of both sides of the display module, rather than directly selecting or executing a specific object, will be described. That is, the additionally executed menus may have nothing to do with a specific object of a previously executed menu. However, any information related to the particular object may be available in the additionally executed menu.

18 is a flowchart illustrating a multitasking method using touch in a mobile terminal according to the present invention.

It is assumed that a specific menu (eg, a first menu) is already executed in the mobile terminal.

Accordingly, various objects are displayed on the execution screen of the first menu, and as described with reference to FIGS. 6 to 17, the user may touch the objects from the front or the rear, and the touch is input. In some cases, you can perform specific functions related to the object.

In addition, an additional menu (for example, a second menu or a third menu) irrelevant to the executed specific menu may be additionally executed. That is, while the first menu is being executed, the user may additionally execute the second menu or the third menu by touching the front or rear surface of the transparent display module. In other words, the multitasking operation may be performed by touching either side of both sides of the transparent display module.

Any one of the two-sided touch method for executing the operation related to the specific object or the two-sided touch method for executing the multitasking operation may be selected through a specific hardware button, a software button, or a predetermined specific command input method.

Since the two-sided touch method for executing an operation related to the specific object has been described above with reference to FIGS. 5 to 16, the following describes an operation method on the assumption that the two-sided touch method for executing the multitasking operation is selected.

When the transparent display module is touched in a state in which the first menu is already executed (S101) (S202), the controller 180 detects which side of the transparent display module is touched through which of the surfaces (S203). The preset second menu or the third menu is executed according to the touch input surface. That is, when a touch is input through the first surface (for example, the front surface) (S204), a preset second menu is executed (S205), and if a touch is input through the second surface (for example, the rear surface), the third menu is preset. Is executed (S206).

In other words, when a touch is input through the first surface, a first menu and a second menu are executed (S207). When a touch is input through the second surface, a first menu and a third menu are executed. It becomes a state (S208). In this case, even if the second menu or the third menu is not directly related to the first menu that is already executed, specific information related to the first menu may be used.

19A and 19B are exemplary diagrams for describing a multitasking method using a touch in a mobile terminal according to the present invention.

Here, FIG. 19A is an exemplary diagram illustrating a screen for writing a message to be transmitted to a counterpart in a video call by executing a memo, schedule, or text message menu when a front surface of both sides of the display module is touched, and FIG. 19B is a rear touch panel. In this case, the memo, schedule, or text message menu is executed to show an example of a screen for editing or creating previously stored contents.

19A and 19B, (a) is an exemplary view showing a video call screen displayed on the front side. That is, FIGS. 19A and 19B are exemplary views illustrating a method of executing the second menu or the third menu as the front or rear surface of the display module is touched while a specific menu (eg, the first menu) is already executed. .

The second and third menus executed in FIGS. 19A and 19B are not directly related to the first menu. That is, the menu is not a menu for directly selecting or executing a specific object (eg, a video call counterpart) displayed on the first menu. However, the second menu and the third menu may selectively use information related to a specific object of the first menu. In other words, assuming that the first menu is a video call menu and the second menu is a short message menu, it means that information of the other party in the video call is available in the second menu.

In the present embodiment, the second menu or the third menu includes a memo, a schedule, or a text message menu. If the execution screen of the second menu or the third menu is displayed, the controller 180 displays the first menu (eg, a video call) screen relatively transparently and executes the execution screen of the second menu or the third menu. Can be displayed relatively clearly. On the contrary, the execution screen of the second menu or the third menu can be displayed relatively transparently, and the first menu (eg, video call) screen can be displayed relatively clearly. The screen processing as described above may be executed until the creation of a memo, schedule, or text message is completed or the transmission is completed, and optionally, the transparent background may be processed as an opaque background.

As shown in (a) of FIG. 19A, when the front surface is touched, the controller 180 controls specific information related to the first menu (for example, the video call menu) (for example, the other party's telephone number). ), A second menu (for example, a short message menu) can be executed. In the execution screen of the second menu, the counterpart information used in the second menu may be displayed together. For example, a thumbnail of the counterpart may be displayed as shown in (b), or an image of the counterpart may be displayed in the background as shown in (c). Alternatively, the name or phone number of the other party may be displayed on one side of the execution screen of the second menu. As shown in (d), when the execution of the second menu is completed, that is, when the multitasking operation is completed, the controller 180 displays the execution screen of the first menu again.

As shown in (a) of FIG. 19B, when the rear surface is touched, the controller 180 controls the third menu (eg, the video call menu) to be completely unrelated to the first menu (eg, the video call menu). : Memo menu). As shown in (b), the controller 180 may change the size of the execution screen of the first menu and display the execution screen of the third menu on one side of the display area. In this case, the first menu or the third menu may be displayed in an overlapping manner by adjusting transparency. As shown in (c), when the execution of the third menu is completed, that is, when the multitasking operation is completed, the controller 180 displays the execution screen of the first menu again.

Of course, other functions not described in the above embodiments may be executed. For example, while you're running Internet browsing, you might want to run games, download files, and view documents.

Meanwhile, when the multitasking operation is performed as described above, a plurality of menu execution screens (or a plurality of menu active windows) may be overlapped and displayed. When each menu execution screen (or menu active window) is referred to as a layer, the top layer is displayed on the front surface, but the bottom layer is hidden by the upper layers, so that it is not displayed on the front surface.

Accordingly, when the menu active window of the lower layer is not visible by the menu active window of the upper layer, the menu active window of the lower layer is applied to the upper layer by applying the double-sided touch input of the present invention. You can easily move it to make it appear.

For example, assume that a plurality of menu active windows (eg, a first menu active window-a fourth menu active window) is displayed. At this time, the user can move the menu active window (for example, the fourth menu active window) of the lowest layer to the top layer by touching it as if pushing the rear, so that the menu active window of the lowest layer is immediately displayed on the front.
