User terminal apparatus and controlling method thereof

1. A user terminal apparatus comprising:

a first body;

a second body mounted on one side of the first body to be slidably connected to the first body;

a transparent display formed on the second body;

a display formed on the first body, and

a controller configured to:

identify the second body being slid from the first body to open the first body to form a first area and a second area in the transparent display, and

based on the identification, provide different functions to the first area and the second area, respectively,

wherein the first area is an area in the transparent display, which overlaps with the first body, and the second area is an area which is a remaining part of the transparent display,

wherein the transparent display comprises a touch panel configured to receive a user touch,

wherein the controller is configured to, based on at least one control menu being displayed only on the first area, activate a partial area of the touch panel corresponding to the first area, and inactivate a remaining area of the touch panel corresponding to the second area on which a first content is displayed,

wherein the controller is configured to display a second content, symmetrical to the first content, on at least one of the first area and the second area based on a user manipulation,

wherein the controller is further configured to:

provide another function to a third area in the display which does not overlap with the transparent display,

based on an outside object being recognized through the second area in the transparent display, control the display to display additional information regarding the outside object on the first area and display at least one control menu on the third area,

based on the outside object being recognized as a sign, control the display to display a map of a region corresponding to the sign on the first area as the additional information, and

based on the outside object including a text, control the display to display a translation of the text on the first area as the additional information, and

wherein the additional information comprises at least one of a map, text translation, an address of a related website, a related image, and a commercial content.

2. The apparatus of claim 1 , wherein the display is one of a light-emitting display, a reflective display and a transparent display.

3. The apparatus of claim 1 , wherein the controller is configured to display a control menu on the third area for controlling the first area and the second area, and inactivate the touch panel.

4. The apparatus of claim 1 , wherein the first body comprises a panel unit configured to receive a user manipulation, and

wherein the controller is further configured to turn off a backlight provided to the panel unit in a close state where the second body covers the first body, and provide the backlight to the panel unit based on the panel unit being exposed as the second body is slid from the first body.

5. The apparatus of claim 1 , wherein the first body comprises a panel unit configured to receive a user manipulation,

wherein the controller is further configured to perform a control operation corresponding to the user touch which is received through the touch panel in a close state where the second body covers the first body, and perform a control operation corresponding to the user manipulation which is input through the panel unit in an open state where the panel unit is exposed as the second body is slid from the first body.

6. The apparatus of claim 1 , wherein the controller is configured to inactivate at least one of the transparent display and the display in a close state where the second body covers the first body.

7. The apparatus of claim 1 , further comprising:

a camera formed on one of the first body and the second body,

wherein the controller is configured to recognize the outside object by identifying an edge of the outside object included in a photographing image of the camera, and search for additional information corresponding to the outside object.

8. The apparatus of claim 1 , further comprising a connector configured to connect the first body and the second body so that the second body is slid from the first body in phase.

9. The apparatus of claim 8 , wherein respective sizes of the first area and the second area change according to a sliding phase of the second body, and

wherein the controller is configured to display a user interface (UI) screen in a different layout according to a size of the first area.

10. A method of controlling a user terminal apparatus including a first body, a second body mounted on one side of the first body to be slidably connected to the first body, a transparent display formed on the second body and a display formed on the first body, the method comprising:

controlling to identify the second body being slid from the first body to open the first body to form a first area and a second area in the transparent display, wherein the transparent display comprises a touch panel configured to receive a user touch; and

based on the identification providing different functions to the first area and the second area, respectively,

based on at least one control menu being displayed only on the first area, activating a partial area of the touch panel corresponding to the first area and inactivating a remaining area of the touch panel corresponding to the second area on which a first content is displayed,

based on a user manipulation, displaying a second content, symmetrical to the first content, on at least one of the first area and the second area,

providing another function to a third area in the display which does not overlap with the transparent display,

based on an outside object being recognized through the second area in the transparent display, displaying additional information regarding the outside object on the first area and displaying at least one control menu on the third area,

based on the outside object being recognized as a sign, displaying a map of a region corresponding to the sign on the first area as the additional information, and

based on the outside object including a text, displaying a translation of the text on the first area as the additional information, and

wherein the additional information comprises at least one of a map, text translation, an address of a related website, a related image, and a commercial content, and

wherein the first area is an area in the transparent display, which overlaps with the first body, and the second area is an area which is a remaining part of the transparent display.

11. The method of claim 10 , wherein the display is one of a light-emitting display, a reflective display and a transparent display.
