The antenna 116, which forms part of the broadcast receiving module 111 (see FIG. 1), can be installed to be able to be drawn out from the terminal body.

A power supply unit 190 for supplying power to the portable terminal 100 is mounted on the terminal body. The power supply unit 190 may be built in the terminal body or may be detachable from the outside of the terminal body.

The rear case 102 may further include a touch pad 135 for sensing a touch. The touch pad 135 may also be of a light transmission type like the display unit 151. [ In this case, if the display unit 151 is configured to output time information on both sides, the time information can be recognized through the touch pad 135 as well. The information output on both sides may be all controlled by the touch pad 135. [ Alternatively, a display may be additionally mounted on the touch pad 135, and a touch screen may be disposed on the rear case 102 as well.

The touch pad 135 operates in correlation with the display portion 151 of the front case 101. The touch pad 135 may be disposed parallel to the rear of the display unit 151. The touch pad 135 may have a size equal to or smaller than that of the display unit 151.

Hereinafter, a related operation of the display unit 151 and the touch pad 135 will be described with reference to FIGS. 3A and 3B.

3A and 3B are front views of a portable terminal for explaining an operation state of the portable terminal according to the present invention.

Various types of time information can be displayed on the display unit 151. [ These pieces of information can be displayed in the form of letters, numbers, symbols, graphics, or icons.

At least one of the letters, numbers, symbols, graphics, or icons may be displayed in a predetermined arrangement for inputting such information, thereby being implemented as a keypad. Such a keypad may be called a so-called " soft key ".

FIG. 3A shows a touch input to a soft key through a front surface of a terminal body.

The display unit 151 may operate as an entire area or may be divided into a plurality of areas and operated. In the latter case, the plurality of areas can be configured to operate in association with each other.

For example, an output window 151a and an input window 151b are displayed on the upper and lower portions of the display unit 151, respectively. The output window 151a and the input window 151b are areas allocated for outputting or inputting information, respectively. In the input window 151b, a soft key 151c in which a number for inputting a telephone number or the like is displayed is output. When the soft key 151c is touched, a number corresponding to the touched soft key is displayed on the output window 151a. When the first operation unit 131 is operated, call connection to the telephone number displayed on the output window 151a is attempted.

FIG. 3B shows the input of a touch applied to the soft key through the rear surface of the terminal body. FIG. 3A shows a case where the terminal body is vertically arranged, and FIG. 3B shows a case where the terminal body is arranged horizontally. The display unit 151 may be configured to convert the output screen according to the arrangement direction of the terminal body.

3B shows that the text input mode is activated in the portable terminal. The display unit 151 displays an output window 151a 'and an input window 151b'. In the input window 151b ', a plurality of soft keys 151c' displayed with at least one of letters, symbols, and numbers may be arranged. The soft keys 151c 'may be arranged in the form of a QWERTY key.

When the soft keys 151c 'are touched through the touch pad 135 (see FIG. 2B), characters, numbers, symbols corresponding to the touched soft keys are displayed on the output window 151a'. As described above, the touch input through the touch pad 135 is advantageous in that the soft key 151c 'can not be blocked by the finger when the touch is input, compared with the touch input through the display unit 151. [ In the case where the display unit 151 and the touch pad 135 are formed to be transparent, the fingers located on the rear side of the terminal body can be visually confirmed, thereby enabling a more accurate touch input.

The display unit 151 or the touch pad 135 may be configured to receive a touch input by scrolling, as well as the input method described in the above embodiments. The user can move a cursor or a pointer located on an object displayed on the display unit 151, for example, an icon or the like, by scrolling the display unit 151 or the touch pad 135. [ Further, when the finger is moved on the display portion 151 or the touch pad 135, the path along which the finger moves may be visually displayed on the display portion 151. [ This will be useful for editing the 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. The one function may be activation or deactivation of the display unit 151 or the touch pad 135, for example.

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

4 is a conceptual diagram for explaining the proximity depth of the proximity sensor.

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

The proximity sensor 141 may be configured to output different proximity signals according to the 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 having proximity sensors capable of sensing three proximity depths 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 (d0), it is recognized as a contact touch. If the pointer is located on the touch screen at a distance less than the distance d1, it is recognized as a proximity touch of the first proximity depth. If the pointer is located on the touch screen at a distance d1 or less and less than the distance d2, the pointer is recognized as a proximity touch of the second proximity depth. If the pointer is located on the touch screen at a distance d2 or more and less than the distance d3, it is recognized as a proximity touch of the third proximity depth. If the pointer is located at a distance d3 or more on the touch screen, it is recognized that the proximity touch is released.

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

Hereinafter, embodiments related to a control method that can be implemented in the terminal configured as above will be described with reference to the accompanying drawings. The following embodiments can be used alone or in combination with each other. In addition, the embodiments described below may be used in combination with the above-described user interface (UI).

The mobile terminal of this embodiment has at least two displays (a first display, a second display) (hereinafter referred to as a dual display). At least one of the dual displays is configured as a touch screen. Also, at least one of the dual displays may comprise a transparent display (TOLED). The touch screen may be configured to be capable of proximity touch or multi touch. The proximity touch is distinguished from a direct touch by detecting access for a touch, and the multi-touch is distinguishable from a single touch because it can detect touch at two or more places at the same time.

The dual display may be configured as a folder type. When the mobile terminal is opened, the dual displays may be disposed at the upper and lower ends, respectively, or may be disposed at the left end and the right end. Each of the displays may be of the same size, or any one of the displays may be configured to be larger or smaller.

In addition, when at least one of the dual displays is configured as a transparent display, when the mobile terminal is closed, information can be output through any one of the displays. For example, if it is assumed that the first display is a transparent display, the image of the first display may be directly output, or the image of the second display may be transmitted through the first display. That is, the mobile terminal can be configured to be used as a dual display when the mobile terminal is opened and as a single display when the mobile terminal is closed.

In addition, the operating characteristics of the dual display can be controlled differently. For example, any one of the displays can be controlled to operate only the input function such as the touch pad without displaying the image information.

In addition, although the dual display is structurally divided into two displays, each display can be driven by further subdividing the display area by software. Each of the subdivided regions may have different operating characteristics. For example, one side area may be set to display only, and the other side area may be set to both display and touch input. Further, it is also possible that one side area is set to enable handwriting input, and the other side area is set to enable only touch input. The operation characteristic is automatically changed according to the operation mode of the predetermined mobile terminal.

In addition, the dual display can be operated separately for each display, and related operations are also possible. For example, a moving picture playback screen may be displayed on the first display and a web browsing screen may be displayed on the second display. In addition, a first broadcast screen may be output to the first display and a second broadcast screen may be output to the second display. In addition, one screen can be divided and output to the first display and the second display.

Or the first display may output a broadcast screen while the second display may output a channel selection screen associated with the broadcast screen. As another related operation, when a character input screen is outputted to the first display, a virtual keypad screen can be outputted to the second display, and when the Paint screen is outputted to the first display, the mouse pad screen can be outputted to the second display have. The dual display may be long in the horizontal direction or long in the vertical direction.

Hereinafter, a method of controlling the operation of the mobile terminal having the dual display will be described. For convenience of explanation, it is assumed that the first display is only capable of display and the second display is capable of both display and touch input.

5 is a flowchart illustrating a method of controlling a mobile terminal having a dual display according to the present invention.

As described above, it is assumed that a first screen including a first object (e.g., an icon) is displayed on the first display, and a second screen including the second object is displayed on the second display (S101). At this time, the second display does not necessarily have to display the second screen.

When a predetermined first signal is input in a state in which any objects pre-assigned to the first display and the second display are displayed as described above (Yes in S102), the control unit displays, in response to the first signal, The first screen displayed on the first display can be moved to the second display and displayed (S103).

Here, the first signal is a signal for instructing movement of a first screen including the first object to a predetermined display, and includes a key input signal, a touch input signal, a voice command signal, a motion detection signal, Or a sound input signal.

If the first screen is displayed on the second display as described above, the user can select or execute the first objects included in the first screen (S104). This is because the second display is capable of touch input.

Meanwhile, when the first screen is moved and displayed on the second display as described above, the second screen displayed on the second display may be displayed on the first display. That is, the positions of the first screen and the second screen are switched and displayed. Alternatively, the first screen may be displayed as an upper layer of the second screen. When the first screen and the second screen are overlapped and displayed, the transparency of each layer can be changed. That is, only the first screen displayed on the upper layer may be displayed, or the second screen and the first screen may be displayed in a superimposed manner in a translucent manner.

If the first object is selected by the user on the first screen displayed on the second display, the controller executes an operation corresponding to the selected object.

If the second signal is input except for the instruction to select or execute the arbitrary object (Yes in S105), the controller may switch the first screen and the second screen to their original state (S106). That is, the first display is displayed on the first display and the second display is displayed on the second display. At this time, the first signal and the second signal can use the same signals (e.g., at least one of a key input signal, a touch input signal, a voice command signal, a motion detection signal, a rotation detection signal, have. The first signal and the second signal are signals generated according to a user's operation of the terminal and can be input through an input unit such as an A / V input unit, a sensing unit, or a user input unit.

In order to select objects displayed on a display (e.g., a first display) having no input function among the dual displays, a mobile terminal having a dual display, ) So as to be able to select arbitrary objects, and then transferring the objects to the original display (e.g., the first display) to display the objects.

FIG. 6 is an exemplary view for explaining a method of moving an object of a mobile terminal according to the present invention.

As shown, it is assumed that icons are displayed on the first display 151a and other icons are displayed on the second display 151b. Hereinafter, any icon displayed on the first display 151a is referred to as a first object 300, and any icon displayed on the second display 151b is referred to as a second object 400. [ The first objects 300 and the second objects 400 may be changed to other information (e.g., still images, moving images, broadcast images, documents) according to the operation of the mobile terminal.

As described above, when the first display 151a does not have a touch input function, the present invention can display any one of the first objects 300 displayed on the first display 151a on the second display 151b. ≪ / RTI >

In one embodiment, the cursor 301 having a specific shape is displayed on any one of the first objects (e.g., arbitrary icons) displayed on the first display 151a, Or the second display 151b, and moves the cursor 301 to select a desired object. For example, by inputting the preset key # 1, the user can select the object corresponding to the key (e.g., the first object). Alternatively, if '2' is written on the second display, the corresponding object (eg second object) can be selected. The above embodiment describes a method of selecting the first objects on the second display while displaying the first objects on the first display.

In another embodiment, after all of the first objects displayed on the first display, or any one of the objects displayed on the second display, are displayed on the second display, You can select objects. After selecting one desired object as described above, the user can move to the first display again. The method of moving the first objects displayed on the first display to the second display may include, for example, directly touching (or proximity touching) a specific area of the second display and dragging the specific area in a specific direction or a specific shape, (E.g., downward as a direction in which the first object is to be moved), or rotates the first display and the second display such that the positions of the first display and the second display are opposite to each other, You can move 1 objects.

In addition, the method of displaying the first objects moved to the second display may, for example, overlay the first objects on an upper layer of the second objects already displayed on the second display. In addition, the first objects may be displayed on the second display while the second objects displayed on the second display may be displayed on the first display. That is, the first object and the second object can be displayed by interchanging the display.

The method for instructing the first object to move back to the first display may include, for example, selecting or executing an object desired by the user as described above, To the first display. Alternatively, the same methods of directing the first objects to move to the second display may be applied.

7 is an exemplary diagram for explaining an object moving method using rotation of a terminal in FIG.

If it is assumed that only the second display among the first display 151a and the second display 151b is touch-capable, it is necessary to select the first objects 300 displayed on the first display, It is necessary to move the display devices 300 to the second display.

That is, as a method of moving the display on which the first objects 300 are displayed, there is a method of moving the first object while fixing the positions of the first display and the second display. For example, when it is assumed that the first display 151a is disposed on the upper side of the folder type mobile terminal and the second display 151b is disposed on the lower side thereof, the first display 151a is displayed on the upper first display 151a The first object 300 can be displayed on the lower second display 151b.

Another method of moving the display on which the first object is displayed is to change the positions of the first display and the second display while maintaining the visual position where the first object is displayed. For example, as shown in FIG. 7, the folder type mobile terminal in which the first display is disposed on the upper side and the second display is disposed on the lower side is rotated to move the second display 151b upward, Assuming that the object 151a moves downward, the first objects 300 are displayed on the second display 151b moved upward. That is, the visual display position (e.g., the upper display position) of the first objects displayed on the upper display of the folder type mobile terminal is maintained.

Accordingly, the user rotates the first display and the second display so that the first objects 300 can be displayed with the touch input function (e.g., the first display 300) while the visual display position (e.g., the upper display position) 2 display 151b. As described above, according to the present invention, even if the dual displays are not all equipped with a high-priced touch screen, there is no inconvenience in selecting the objects displayed on the respective displays, and the user can have fun.

As described above, in the mobile terminal having a dual display, a method of moving objects displayed on the one-side display to select objects displayed on the one-side display, then displaying the objects on the original display after selecting the objects has been described. Hereinafter, a method of selecting objects displayed on the other side display and displaying a screen related to the selected objects will be described.

8 is an exemplary diagram for explaining a method of selecting an object of a mobile terminal and a method of displaying the selected object according to the present invention.

When the first objects displayed on the first display are displayed on the second display as described above, the user can select a specific object displayed on the second display using any selection means (e.g., a finger, a pen, etc.) .

As a method for selecting the object, at least one of a key, a proximity touch, a multi-touch, a touch and drag, a rotation of the terminal, a shake, an inclination, an impact, a voice command, a wind input, or an impact sound may be used.

The user can selectively use one of the above methods in accordance with a desired purpose. For example, when a specific object is to be enlarged or reduced and displayed, multi-touch can be used. In the case of a single-touch and multi-touch, a scroll speed can be changed, ), The number of pages can be set differently, and a detailed screen of a specific object can be displayed on another display by using the proximity touch. In addition, the number of objects to be displayed may be set differently according to the number of touches by moving to the second display.

On the other hand, objects that are moved to another display to receive the selection may be enlarged or reduced according to the size of the display. For example, if the size of the second display is larger than that of the first display, the size of the first objects can be automatically changed to a larger size. However, the sizes of the first objects are not necessarily changed, and the sizes of the first objects may be maintained as they are.

Also, the objects moved to another display in order to receive the selection may be increased or decreased in length depending on the shape of the display. For example, if the horizontal length of the second display is longer than the vertical length, the vertical length of the first objects can be increased or the horizontal length can be reduced.

9 is a diagram illustrating a method of controlling an additional function of a mobile terminal having a dual display according to the present invention.

As described above, the present invention can change not only the objects displayed on the first display or the second display, but also the operation or configuration option of each display on the second display. In other words, when the user operates the mobile terminal (S201), a preset specific signal (e.g., a first signal or a second signal) is generated (S202).

Accordingly, the control unit 180 detects the operation pattern using the specific signal (S203). Then, the detected operation pattern is compared with the operation pattern previously stored in the database (or memory), and the function set corresponding to the operation pattern is detected (S204). Then, the detected function, that is, the function corresponding to the operation pattern is immediately executed (S205).

Here, the database stores information related to an operation pattern set by the user, an operation pattern set as a default, and functions corresponding to each operation pattern.

The functions include a function (S206) for changing an operation characteristic such as transparency or color of the first display or a second display, a function (S207) for executing a configuration menu related to each display, (S208) for controlling to be visible.

The operation may be configured to be executed corresponding to a specific area of the second display, and may be configured to be executed corresponding to a specific operation pattern. Further, the specific area and the specific operation pattern may be combined and executed. The operation pattern refers to a touch input pattern, such as a circle or triangle, which is dragged to a specific shape or dragged to a dotted line. In addition, the operation pattern can be generated by the user, and the user can directly correspond the operation (or the configuration item) to be executed in correspondence with the generated operation.
