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 (the mobile communication 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.

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.

6A shows an object such as an icon or a menu item in a circle for convenience of description. As illustrated 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 area 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.

7 is an exemplary view showing an implementation of a content playback method according to an embodiment of the present invention. As shown in the drawing, when a finger or a stylus pen comes close to the touch screen while the content is being played, the music file or video content being played is paused. At the same time, a playback progress bar is displayed at the bottom or one side of the screen. The controller, which receives the proximity touch information from the touch screen, displays the playback position information of the current content in a translucent manner. That is, assuming that the total content is 100, the playback position of the current content is displayed in the form of a percentage value.

If the user scrolls to the left or right or up or down of the playback progress bar while maintaining the proximity touch state, the controller receives movement information and displays the current playback position by changing the percentage value. That is, as shown, when the content is being played about 42% and scrolls to the right while maintaining the proximity touch, the content is displayed at the position of 90%. In a similar manner, if the user moves to the left from the current touch position while maintaining the proximity touch, the playback position display is changed in the form of decreasing percentage value. In other words, the percentage value for the entire content is displayed in a form of decreasing toward the left and increasing toward the right. Of course, if the playback progress bar is displayed vertically on the side of the screen may be displayed while moving up and down.

When scrolling is complete, the user releases the proximity touch. That is, when the proximity touch is performed using the stylus pen or the finger and the stylus pen or the finger is away from the touch screen, the proximity touch is released. This is detected by a touch screen that includes a proximity sensor. Accordingly, the controller recognizes the final proximity touch position. The controller controls the playback operation by searching for a content playback location corresponding to the final proximity touch location.

8 is an exemplary view of a screen according to another embodiment of the present invention. As described with reference to FIG. 7, when the playback progress bar proximity touch operation is performed while the content is being played, the content being played is paused and the current playback position is semi-transparently displayed on the playback progress bar as a percentage value.

That is, when the initial proximity touch position is about 30% and the user moves to the right while maintaining the proximity touch, the position is displayed as the position of 70%. If the user maintains the proximity touch state for more than a predetermined time in this state, the controller searches for the position of the content corresponding to the current proximity touch position. Control content to be played from the searched position.

9 is an exemplary view of a screen according to another embodiment of the present invention. That is, the case in which the playback speed can be controlled for each playback section of the content is shown. For example, when the content currently being played corresponds to 25% of the total content, when the proximity touch is made, the content being played is paused. In the playback progress bar area, the current playback position is displayed semitransparently as a percentage value and the current playback speed is displayed. In this state, if the user scrolls to the right while maintaining the proximity touch, the percentage value for the playback position is displayed as 70%, for example. At this time, the reproduction speed display is 1x (1x) → 1.5x (1.5x) → 2x (2x) → 0.5x (0.5x) → 1x (1x). It may be displayed while being repeated at a predetermined time in the form of. The user may set the playback speed in a section from the position where the first proximity touch is performed to the scrolling position and the current playback position that maintains the proximity touch.

For example, as shown, the first proximity touch is made at 25%, and when selecting 1.5 times speed (1.5x) at the position of 70%, and selecting 0.5 times speed (0.5x) at the position of 70%. Cases may occur.

In this case, each reproduction speed is made as follows. First, when 1.5x speed is selected at 70% playback position, playback is performed at 1x speed from 0% to 25% position, 1.5x speed (1.5x) from 25% position to 70% position, and 100% playback from 70% position. Up to the position, the content is played back at the speed of 1x (1x). This information can be stored in memory as needed. That is, the user can set the desired playback speed in accordance with the content to be played.

On the other hand, if the content is similar but needs time to think while learning or playing a language, it may be necessary to slow down the playback speed. If this is the case, in contrast to the above, 1x speed from the 0% position to the 25% position, 0.5x (0.5x) from the 25% position to the 70% position, and 1x again to the playback position 100% from the 70% position The content is played at a speed of).
