3 is a cross-sectional view of a display having a double bond structure according to the present invention.

As shown in the figure, the display according to the present invention has a structure in which two display units 210 and 220 are superimposed as upper and lower layers. Here, the two display units (e.g., the first display unit 210 and the second display unit 220) are each configured as a touch screen.

For example, a first display unit (= a first touch screen) having a first display and a first touch pad coupled thereto is disposed on a first layer, and a second display and a second touch pad (= Second touch screen) is disposed on the second layer.

Here, the first display may be an LCD, and the second display may be a transparent display. The transparent display may be formed of Graphene.

Here, the second display unit 220 is superimposed on the first display unit 210. The second display unit is movable. Therefore, the second display unit can be moved so as to completely overlap the first display unit, overlap only a part of the first display unit, or prevent overlapping at all.

Here, the second display unit may be moved by a sliding method, a folder method, a swing method, or a swivel method. And a groove or slot suitable for each of the above-described schemes can be formed on one side of the body of the mobile terminal. Further, coupling means (not shown) may be further added to prevent the second display unit from being completely separated from the main body of the mobile terminal when the second display unit is moved, and the second display unit may be prevented from being undesirably disconnected by the user can do.

The first display and the first touch pad, and the second display and the second touch pad may be independently connected to the controller 180. Therefore, independent control is possible regardless of whether the first display unit and the second display unit overlap each other. Or the pressure sensed by the second touch pad may be transmitted to the first touch pad through the second display and the input coordinates may be transmitted to the controller 180. [

The second display can control transparency according to the characteristics of graphene. The transparency can be controlled from 0% which is completely transparent to 100% which is opaque. For example, the user can control the transparency of the second display by touching a specific point (e.g., lower side) of the display unit and then flicking (or dragging) the same to another specific point (e.g., upper side). That is, the transparency becomes 100% as the upper side flicking is performed, and the transparency becomes 0% as the lower side flicking becomes.

Also, the controller 180 can control on / off of the second display under any circumstances by using a touch. For example, if the user touches a specific point (eg, left) on the display section and then flicking (or dragging) to another specific point (eg, right) turns off the second display, ) To a specific point (for example, left), the second display can be turned on.

In addition, the controller 180 can link the transparency control and the on / off control. For example, if the transparency of the second display is set to a predetermined value (e.g., transparency of 10%), the second display is turned off if the transparency of the second display is set to be less than a predetermined specific value The second display can be turned on.

If the transparency of the second display is set to a predetermined value (e.g., transparency of 90%), the first display is turned off and the transparency of the second display is set to a predetermined value (e.g., transparency of 90% The first display can be turned on. The on / off of the first and second displays according to the transparency of the second display described above is an embodiment, and the first and second displays may be turned on / off regardless of the transparency of the second display.

As described above, the present invention can control the on / off and transparency of the display according to the flicking (or dragging) direction, and the control method is not limited to the method described in the above embodiment. For convenience of explanation, the first display unit 210 and the second display unit 220 are referred to as a first display or a second display.

Hereinafter, a method for controlling the operation of a mobile terminal having a display having a double-bonded structure will be described.

4 is a diagram illustrating an example of a character input method using a display having a double bond structure according to the present invention.

The control unit 180 displays an execution screen corresponding to the character input mode on the first display 210. In this case, And a character input screen for inputting the character on the second display 220. [ That is, a plurality of soft keys may be arranged in the second display in which at least one of a character, a symbol and a number is displayed, and the soft keys may be arranged in the form of a QWERTY key.

At this time, the priority for receiving the touch of the user may be changed depending on whether the second display is on. For example, when the second display is on, the priority of receiving a touch is higher than that of the first display. That is, when the soft keys are displayed at the same coordinates of the first display and the second display, the soft key displayed on the second display can be input when the second display is on, The user can input the soft key displayed on the first display. If there is a soft key area of the second display and a non-overlapping soft key area of the first display, the soft key displayed on the first display may be input.

Accordingly, the user can select a display to receive a touch through on / off of the second display. For example, when the user turns on the second display, the character input screen is displayed overlaid with the execution screen displayed on the first display. Accordingly, the user can input the soft key displayed on the second display while referring to the content of the execution screen viewed through the second display. Also, the user can turn off the second display and prevent the character input screen from being displayed even when the input of the contents is not completed. The second display may be turned on to display the character input screen again to continuously input the contents. That is, the display of the character input screen can be easily controlled even during the input of characters according to the convenience of the user.

As described above, since the entire display area can be used as an input screen and the contents of an execution screen can be used, the present invention facilitates securing a work space.

5 is an exemplary diagram for explaining a video output method using a display having a double bonding structure according to the present invention.

The controller 180 displays a list of the images (e.g., a thumbnail or a text) on the first display 210, assuming that an arbitrary image output mode (e.g., a photo album, And can select any one of them from the user. In addition, the second display 220 displays the selected image in the image list on the full screen.

According to the setting, the image list may be output to the second display, and the first display may display the image selected in the image list on the full screen. According to the present invention, the second display can be easily turned on / off, so that it is preferable to output the image list to the second display and display the selected image on the first display in the full screen on the first display.

On the other hand, when the specific image selected in the image list is displayed on the second display in full screen, the controller 180 controls the transparency of the second display to prevent the first display from being displayed. When the transparency of the second display is controlled to be opaque as described above, the controller 180 may turn off the first display to save power.
