Such a keypad may be called a so-called " soft key ".

3 is a conceptual diagram for explaining a method of controlling a touch operation of a display unit of a mobile terminal according to the present invention.

Here, the display unit 151 or the display module 151 is formed by overlapping the first and second display units 155 and 156.

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 terminal is in a closed state), the TOLED 155 is arranged to overlap 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 objects 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 object 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 object displayed on the TOLED 155 may also be displayed on the LCD 156 according to 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.

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).

Hereinafter, the mobile terminal according to the present invention can be divided into a mobile terminal having a dual display and a mobile terminal having a single display. In all embodiments, the mobile terminal with the single display or the dual display has a transparent display. In addition, a non-transparent display may be additionally provided.

The transparent display and the non-transparent display may be overlapped or separately formed. For example, the single display may be configured as a single module or a transparent display by superimposing a transparent display and a non-transparent display, and the dual display may include a transparent display and a non- will be.

Hereinafter, in all embodiments, the transparent display may be referred to as TOLED (Transparent OLED), and the non-transparent display (opaque display) may be referred to as an LCD (Liquid Crystal Display). However, the transparent display and the non-transparent display are not intended to be limited to TOLED and LCD, respectively.

In the mobile terminal according to the present invention, the LCD operates as a main display and TOLED operates as a sub display. If the TOLED is operated alone, the driving of the LCD may be blocked so as not to interfere with the display of the TOLED. The touch screen may be used as a touch screen by superimposing the touch pad on either the upper side or the lower side of the TOLED and the LCD.

Hereinafter, it is assumed that the TOLED and the LCD operate on a touch screen, although not mentioned in all embodiments of the present invention.

4 is a diagram illustrating a first embodiment for explaining a stereoscopic effect applying method of a mobile terminal according to the present invention.

As shown, the mobile terminal assumes that a camera function is executed and a preview image is output. It is assumed that the preview image is a group portrait photograph.

The control unit 180 outputs the preview image to the LCD 156. [ Accordingly, the user can see the image outputted through the TOLED 155 overlaid on the LCD 156. [ At this time, the preview image is a planar (2D-shaped) image. In the center of the preview image, a focal image (e.g., a rectangular frame or a circular frame) 210 indicating the focal position of the camera may be output.

In general, the focal point is the center of the camera lens, i.e., the center of the preview image. The user can then focus on the desired object by placing the focus image. In this embodiment, the focus position of the camera can be changed while the photographing direction of the camera is fixed. For example, a user can directly touch or touch a specific object or a specific point on a preview image using a touching means (e.g., a finger or a touch pen).

Accordingly, the controller 180 may output the object on which the focus image is located to the TOLED 155. The object output to the TOLED 155 may be removed from the LCD 156. For example, the control unit 180 may select an object in which the focal point image 210 is located, and cut the selected object from the preview image. The controller 180 may cut the object along the outline of the object or may cut the object into a frame of a specific shape (e.g., a circle, an ellipse, a rectangle, etc.). And output the cut object to the TOLED 155 at the same position. Accordingly, the objects 221, 222, and 223 cut out from the LCD 156 are projected while being identical in position in the preview image.

Even if the specific object is removed from the LCD 156 as described above, the object is displayed on the TOLED 155. Therefore, when the user views the image from the front of the display unit, the object may appear to have not been removed.

In the present embodiment, an effect that is projected from other objects in the preview image as described above is referred to as a stereoscopic effect.

On the other hand, in the above example, a specific object selected from the user displayed on the LCD 156 is removed from the LCD 156 and transferred to the TOLED 155 for display. However, the control unit 180 may not remove the object output to the TOLED 155 from the LCD 156. Accordingly, the object in which the focal point image 210 is located is displayed on the LCD 156 and the TOLED 155 at the same time. In addition, the object has an effect of protruding from other objects of the preview image.

When the user arbitrarily selects a specific object of the preview image by using the touching means, the controller 180 displays the selected specific object on the LCD 156 in the TOLED 155 and displays the selected specific object And can be simultaneously displayed on the LCD 156 and the TOLED 155. At this time, the controller 180 may further blur the remaining objects not selected in the LCD 156 to further emphasize the object displayed on the TOLED 155. [ That is, various special effects that can display the selected object from the user and the unselected objects can be additionally applied.

5 is a diagram illustrating a second embodiment for explaining a stereoscopic effect applying method of a mobile terminal according to the present invention.

As described above, it is assumed that the mobile terminal executes a camera function and outputs a preview image. It is assumed that the preview image is a group portrait photograph.

Here, the controller 180 may recognize the faces of the objects displayed in the preview image. The mobile terminal according to the present invention may store an arbitrary face recognition algorithm (not shown) in the memory 160 for the face recognition. The controller 180 can recognize faces of the objects displayed on the preview image or the image retrieved from the photo album using the face recognition algorithm.

When the face of the objects is recognized, the controller can move the recognized face from the LCD 156 to the TOLED 155 and display the face. Or frames 231 and 232 indicating that the face has been recognized. For example, the control unit 180 may cut out the face-recognized object from the preview image of the LCD 156 and output it to the TOLED 155 at the same position. Accordingly, the face recognized object is seen to be protruded. The control unit 180 may copy the object output from the TOLED 155 to the TOLED 155 without removing the object from the LCD 156,

When the face recognition of all the objects displayed on the preview image is completed as described above, the controller 180 can move the objects displayed on the TOLED 155 back to the LCD 156 and display the objects. However, if an object whose face is not recognized remains, the object whose face is not recognized may be displayed on the LCD 156, and objects whose face is recognized may be displayed on the TOLED 155. Or all the objects may be displayed on the LCD 156 while the faces 231 and 232 may be displayed on the faces recognized objects. Accordingly, the user can easily distinguish between a face-recognized object and an object whose face is not recognized.

If there is an object 232 to which the identification information is to be recognized among the recognized objects, the user directly touches or touches a specific object displayed on the TOLED 155 using a touching means (e.g., a finger or a touch pen) Touch to select. When a specific object is selected as described above, the objects other than the selected object may be displayed on the LCD 156. [

When the face recognition of all the objects displayed on the preview image is completed and the specific object 232 recognized as the face is selected from the user, the controller 180 displays the identification information corresponding to the selected object 233 can be displayed on the TOLED 155. Also, when the face recognized objects are displayed on the TOLED 155, the identification information 233 may be displayed together. For example, the identification information may be any one of information stored in a phone book, such as a name of a face-recognized object, a phone number, and a nickname.

The identification information 232 of the specific object may disappear when the specific object is selected again and disappear when another specific object is selected. Also, the identification information of the specific object may be continuously displayed together with the identification information even if another specific object is selected. The object on which the identification information is displayed may be displayed on the LCD 156 to the TOLED 155 and the object on which the identification information disappeared may be displayed on the TOLED 155 to the LCD 156. [ When the objects are displayed on the LCD 156 or the TOLED 155 as described above, the user can feel a stereoscopic effect.

6 is a diagram illustrating a third embodiment for explaining a stereoscopic effect applying method of a mobile terminal according to the present invention.

As described above, it is assumed that the mobile terminal executes a camera function to output a preview image. It is assumed that the preview image is a group portrait photograph.

The user can select one of the specific objects displayed on the preview image by directly touching or touching with proximity using touch means (e.g., a finger or a touch pen). The control unit 180 may display the frames 241, 242, and 243 indicating the selected object. The frame may be displayed by being moved to the newly selected object when the user selects another specific object.

Also, when the frame is displayed as described above, the user can move the frame to another object by using a scroll button (not shown). The user can also touch the frame and drag it to another specific object. That is, the user can select a specific object by dragging the frame.

In addition, a magnet effect can be applied to the frame. For example, the magnet effect is automatically displayed as the frame is dragged onto the particular object, even if the user does not drag the frame further when the frame approaches the particular object.

Also, when the user multi-touches two or more objects displayed on the preview image, the controller 180 may display a frame 243 of a size that can include all of the multi-touched objects. The frame may be set to a specific shape (e.g., contour, circle, ellipse, square, etc.) of the object. The multi-touch may mean touching two or more objects at the same time or touching two or more objects continuously within a preset specific time. The objects in which the frame is displayed may be automatically selected after a certain time, or may be selected when the user touches the frame again (double-touch). Here, it is not intended to limit the selection method of the specific object by the above-described method. Meanwhile, the selected object may be deselected by a toggle method (for example, a method of reselecting the selected object).

When the specific objects are selected as described above, the control unit 180 displays the selected objects to the TOLED 155, and does not change the color. The unselected objects are displayed on the LCD 156 as they are, and color (e.g., black and white), lightness, brightness, etc. may be changed. Whenever a user selects a specific object, the selected objects are changed from a monochrome state to a color state, and at the same time, transferred from the LCD 156 to the TOLED 155 and displayed. When the objects displayed on the TOLED 155 are deselected, the color state is changed to the black and white state, and at the same time, the TOLED 155 can be transferred to the LCD 156 and displayed. The stereoscopic effect may be displayed depending on the display position and the color state of the selected and unselected objects.
