The rear case 102 may be further equipped with a touch pad 135 for sensing a touch. Like the display unit 151, the touch pad 135 may also be configured to have a light transmission type. In this case, if the display unit 151 is configured to output visual information from both sides, the visual information may be recognized through the touch pad 135. The information output on both surfaces may be controlled by the touch pad 135. Alternatively, a display may be additionally mounted on the touch pad 135, and a touch screen may also be disposed on the rear case 102.

The touch pad 135 operates in association with the display unit 151 of the front case 101. The touch pad 135 may be disposed in parallel to the rear of the display unit 151. The touch pad 135 may have the same or smaller size as the display unit 151.

Hereinafter, the 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 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.

In order to input such information, at least one of the letters, numbers, symbols, graphics, or icons may be displayed in a predetermined arrangement so as to be implemented in the form of a keypad. Such a keypad may be called a so-called " soft key ".

3A illustrates receiving a touch applied to a softkey through the front of the terminal body.

The display unit 151 may operate in an entire area or may be operated in a divided manner. 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. In the input window 151b, a soft key 151c displaying a number for inputting a telephone number or the like is output. When the softkey 151c is touched, a number or the like corresponding to the touched softkey is displayed on the output window 151a. When the first manipulation unit 131 is operated, a call connection to the telephone number displayed on the output window 151a is attempted.

3B illustrates receiving a touch applied to a softkey through the rear of the terminal body. If FIG. 3A is a portrait in which the terminal body is arranged vertically, FIG. 3B illustrates a landscape in which 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 terminal. The display unit 151 displays the output window 135a and the input window 135b. In the input window 135b, a plurality of softkeys 135c on which at least one of letters, symbols, and numbers are displayed may be arranged. The softkeys 135c may be arranged in the form of a QWERTY key.

When the soft keys 135c are touched through the touch pad 135, letters, numbers, symbols, etc. corresponding to the touched soft keys are displayed on the output window 135a. As described above, the touch input through the touch pad 135 has an advantage of preventing the softkey 135c from being blocked by the finger when touched, as compared with the touch input through the display unit 151. When the display unit 151 and the touch pad 135 are transparent, the fingers located at the rear of the terminal body can be visually checked, and thus more accurate touch input is possible.

In addition to the input methods disclosed in the above embodiments, the display unit 151 or the touch pad 135 may be configured to receive a touch input by scrolling. By scrolling the display unit 151 or the touch pad 135, the user may move an object displayed on the display unit 151, for example, a cursor or a pointer located at an icon. 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 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 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 be configured according to the type of touch and the touch time. At least one image from the list of images 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. 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 by a long proximity touch (a close touch lasting at least 2 seconds to 3 seconds or more) for the TOLED 155 and a slide (movement of the proximity touch corresponding to the drag) detected. The same applies to the case.

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 the proximity touch recognition region and the tactile effect generation region.

6A shows 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.

Hereinafter, embodiments related to a key control process of a keypad displayed on the touch screen 151 in the terminal 100 configured as described above will be described with reference to the accompanying drawings. Of course, the embodiments described below can be used alone or in combination with each other.
