It cannot be seen through the transparent display unit 151.

Some transparent mode or some opaque mode means a mode in which only a specific area of the first transparent display panel 151a operates in the opaque mode, and the remaining areas of the first transparent display panel 151a operate in the transparent mode.

5B is a text message transmission screen when the transparent display unit 151 or 135 of FIG. 3A or 3B operates in some opaque mode.

Referring to FIG. 5B, the controller 180 of FIG. 1 drives both the first transparent display panel 151a and the second transparent display panel 151b, and the second transparent display panel 151b is the first transparent display panel. It drives so that a light source may irradiate from the specific area | region of 151a.

As a result, the front user of the mobile terminal may display items (transmitted / received text messages, keypads) displayed on the first transparent display panel (151a of FIG. 3A or 3B) and objects located at the rear corresponding to an area other than a specific area ( Cups and cans) can be seen through the transparent display unit 151.

A rear user of the mobile terminal may also display an item (keypad) displayed in an area other than a specific area of the first transparent display panel 151a of FIG. 3A or 3B, and a user located in front of the mobile terminal corresponding to an area other than the specific area; or Other objects (not shown) may be seen through the transparent display unit 151.

However, since a text message, which is an item displayed on a specific area of the first transparent display panel 151a of FIG. 3A or 3B, is not visible to a user located at the rear of the mobile terminal, a security state may be maintained.

The controller 180 of FIG. 1 may not only control the transparent mode or the opaque mode with respect to the entire surface of the first transparent display panel 151a of FIG. Control can be in transparent or opaque mode.

The controller (180 of FIG. 1) may determine an area of the first transparent display panel 151a corresponding to the received specific input as a specific area, and control only the specific area to operate in an opaque mode.

Here, the specific input may be a touch input, a zoom in / zoom out touch input, an operation of an operation key or a function key, a call reception, a text message reception, or another notification reception signal.

The controller 180 of FIG. 1 may determine a specific region according to the type of a specific input.

For example, when a specific input is an input for designating an area such as a touch input or a zoom in / zoom out touch input, the controller (180 of FIG. 1) may receive a region of a range set based on a point where a specific input is received, and a specific input is received. The area of the point that is diagonally formed or the received specific area and the area of the first transparent display panel determined by the set method may be determined as the specific area.

In addition, when an operation of the operation key or a function key, a specific input is a call reception, a text message reception, or other notification reception signal, the controller (180 of FIG. 1) may include a first transparent display in which an item to be displayed is displayed after the specific input is received. An area of the display panel may be determined as a specific area.

In addition to the above methods, a specific area corresponding to a specific input may be determined in the first transparent display panel in various ways.

When the second transparent display panel is disposed between the two first transparent display panels to operate in the dual mode, the controller 180 of FIG. 1 may independently control the two first transparent display panels.

That is, different items may be displayed on the two first transparent display panels, and different processing results may be displayed according to the received input.

In the dual mode, when a specific input is received through one of the two first transparent display panels, the controller (180 of FIG. 1) may select a specific area corresponding to the specific input from the first transparent display panel to which the specific input is input. You can decide.

When the controller (180 of FIG. 1) drives the second transparent display panel to irradiate the light source to the determined specific region, the light source is irradiated to the corresponding region of the other first transparent display panel to be opaquely controlled.

As a result, in a dual mode, when a specific input is received from one of the two first transparent display panels, the controller (180 of FIG. 1) determines a specific area from the first transparent display where the specific input is received, and then irradiates a light source. Since the light source is also irradiated to another area of the first transparent display corresponding to the specific area, corresponding areas of the two first transparent display panels are opaquely controlled.

In the dual mode, the controller 180 of FIG. 1 may display the same item on two first transparent display panels, but invert the item on one of the two first transparent display panels. In this case, the user may see the same item from two first transparent display panels.

The controller (180 of FIG. 1) considers the position of the inverted displayed item when a specific input is received through any one of the two first transparent display panels while inverting and displaying the same item on the two first transparent display panels. The specific area may be determined from the two first transparent display panels. In this case, the specific area means an area corresponding to two first transparent display panels.
