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.

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 transparently, 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 (d ₀ ), it is recognized as a contact touch. If the pointer is located on the touch screen at a distance less than the distance d ₁ , it is recognized as a proximity touch of the first proximity depth. If the pointer is located on the touch screen at a distance of d ₁ or more and less than distance d ₂ , it is recognized as a proximity touch of the second proximity depth. If the pointer is located on the touch screen at a distance of d ₂ or more and less than d ₃ distance, it is recognized as a proximity touch of the third proximity depth. If the pointer is positioned apart from the touch screen by a distance d ₃ or more, 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.

5 is a conceptual diagram for explaining a control method for a touch operation in a form in which a pair of display units 155 and 156 are overlapped.

The terminal shown in this figure is a folder type terminal connected to a main body so that a folder portion is foldable. The first display unit 155 mounted on the folder unit may be of a light transmitting type or a transparent type such as TOLED or the second display unit 156 mounted on the main body may be a form that does not transmit light like an LCD. The first and second display units 155 and 156 may be configured as a touch screen capable of touch input, respectively.

For example, when a touch (a contact touch or a proximity-touch) to the first display unit or the TOLED 155 is detected, the control unit 180 determines whether the touch At least one of the images displayed in the TOLED 155 may be selected or run.

Hereinafter, with respect to the manner in which the information displayed on the other display unit or the LCD 156 is controlled when touching the TOLED 155 exposed to the outside in an overlapped form, a touch, a long touch, a long touch and drag ), And so on.

In the overlapped state (the mobile communication terminal is in a closed state), the TOLED 155 is disposed in a superimposed manner on the lower side of the LCD 156. In this state, if a touch such as a long touch (for example, a touch that lasts for 2 seconds to 3 seconds) is detected in a manner different from the touch for controlling the image displayed on the TOLED 155 in advance, ) 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 according to the execution of the selected image is displayed on the TOLED 155.

The long touch may also be used to selectively move a desired one of the entities displayed on the LCD 156 to the TOLED 155 (without performing any action thereto). That is, when a user selects one area of the TOLED 155 corresponding to a specific entity of the LCD 156 In the case of a long touch, the control unit 180 moves the corresponding object to the TOLED 155 to be displayed. The entity displayed on the TOLED 155 may also be displayed on the LCD 156 by a predetermined touch input to the TOLED 155, for example, flicking, swirling, and the like. In this figure, the menu No. 2 displayed on the LCD 156 is displayed on the TOLED 155.

If another input, for example, a drag, is detected in addition to the long touch, the control unit 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, As shown in FIG. In this drawing, a case where a preview (male photograph) is performed on the menu No. 2 (image file) is illustrated.

The control unit 180 displays a selection cursor (or a selection bar) of the LCD 156 in the state that the preview screen is being output, while dragging toward another image is further performed on the TOLED 155 while maintaining the long touch And displays the image selected by the selection cursor on a preview screen (female photograph). Thereafter, when the touch (long touch and drag) ends, the controller 180 displays the first image selected by the long touch.

When the slide (the operation of the proximity touch corresponding to the drag) is detected together with the long proximity touch (the proximity touch continuing for at least 2 seconds to 3 seconds) to the TOLED 155 .

When a touch operation other than those described above is detected, the controller 180 can operate in the same manner as a general touch control method.

The control method for the touch operation in the overlapped form can 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.

FIGS. 6A and 6B are views referred to the description of the proximity touch recognition area where the proximity signal is detected and the haptic area where the tactile effect occurs.

6A shows objects such as icons and menu items in a circular form for convenience of explanation. The area of the object displayed on the display unit 151 can be divided into a first area A in the center and a second area B surrounding the center area as shown in FIG. 6A. The first region A and the second region B can be configured to generate tactile effects having different intensities or patterns. For example, when the second region B is touched, a first vibration is output, and when the first region A is touched, a second vibration larger than the first vibration is output.

In the case where the proximity touch recognition area and the haptic area are simultaneously set in the area where the object is displayed, the haptic area where the tactile effect is generated and the proximity touch 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, the area including the first area A and the second area B may be a proximity touch recognition area, and the first area A may be set as a haptic area.

(N > 4) as shown in Fig. 6 (a), as shown in Fig. 6 (b) It is also possible to divide into two areas. Each divided region can be configured to generate a tactile effect with 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 can be set differently according to the use environment.

The size of the proximity touch recognition area may be changed depending on the proximity depth to the display unit 151. [ That is, as shown in (a) of FIG. 6, the corresponding proximity touch recognition area may be gradually reduced to 'C', 'B', and 'A' according to the proximity depth to the display unit 151, Or the contiguous touch recognition area corresponding to the proximity depth to the display unit 151 may be gradually increased. In this case as well, the haptic area can be set to a constant size regardless of the proximity depth to the display unit 151, such as the 'H' area shown in FIG. 6B (b).

 In the case of dividing the area in which the object is displayed for the setting of the haptic area or the proximity touch recognition area, in addition to the concentric segmentation as shown in Fig. 6A, segmentation in the horizontal direction or vertical direction, radial segmentation, And various methods such as partitioning can be used.
