Abstract

A display unit includes a transparent light emitting element and displaying information on both sides thereof; a sensing unit for detecting the direction in which the screen of the display unit faces; and a controller for determining a placed state of the display unit according to the detected screen direction and changing information displayed on the display unit according to the determined placed state of the display unit. The screen direction may be one of a first direction in which a front surface of the display unit faces upward, and a second direction in which a rear surface of the display unit faces upward. By using the transparent display device, information can be displayed by using both surfaces of the display device, and displayed information can be changed according to a placed state of the display device. Thus, the users'"'"' interest and fun can be aroused and user convenience can be provided.

Claims

1. A mobile terminal comprising:

a display unit for displaying information;

a sensing unit for detecting a placed state of the display unit; and

a controller for changing information displayed on the display unit according to the detected placed state of the display unit.

2. The mobile terminal of claim 1, wherein the display unit is implemented as a transparent organic light emitting element.

3. The mobile terminal of claim 1, wherein the display unit displays information by using both surfaces thereof.

4. The mobile terminal of claim 1, wherein the controller determines the placed state according to a screen direction in which the screen of the display unit faces.

5. The mobile terminal of claim 4, wherein the screen direction is one of a first direction in which a front surface of the display unit faces upward and a second direction in which a rear surface of the display unit faces upward.

6. The mobile terminal of claim 1, wherein the controller displays information displayed on the display unit in a forward direction according the placed state of the display unit.

7. A display method of a mobile terminal comprising:

detecting a placed state of a display device; and

changing information displayed on the display device according to the detected placed state.

8. The method of claim 7, wherein the display device is transparent when light is not emitted, and displays information on both surfaces thereof.

9. The method of claim 7, wherein the detecting of the placed state of the display device comprises:

detecting a screen direction of the display device; and

determining the placed state of the display device according to the detected screen direction.

10. The method of claim 9, wherein the screen direction is one of a first direction in which a front surface of the display unit faces upward and a second direction in which a rear surface of the display unit faces upward.

11. The method of claim 7, wherein, in changing the information displayed on the display device, the information displayed on the display device is displayed in a forward direction according to the placed state of the display device.
