Abstract

A display device, a mobile terminal, and a method for displaying a second screen image are discussed. The display device according to one embodiment includes an interface unit configured to be connected to a mobile terminal having a first display unit displaying a first screen image in a first display direction; a second display unit; and a controller configured to receive information related to the first screen image, and display a monitor window for displaying a second screen image corresponding to the first screen image on the second display unit. The second screen image is displayed in the first display direction. The controller is further configured to receive a user command to intend the monitor window to be oriented in a second display direction and control the monitor window to be oriented in the second display direction according to the user command, and transmit a control signal.

Claims

1. A mobile terminal, comprising:

a first display unit configured to display a mobile screen image;

an interface unit configured to be connected to an external display device having a second display unit for displaying a monitor window for displaying a monitor screen image; and

a controller configured to;

receive a control signal relating to a modification of the mobile screen image from the external display device, wherein a housing of the mobile terminal is in a first orientation direction,

control the mobile screen image to be modified in response to the control signal, even though the first orientation direction of the housing of the mobile terminal is not changed into a second orientation direction, and

provide a modified mobile screen image to the external display device,

wherein the external display device maintains the monitor window in the first orientation direction, even though an orientation direction of the mobile screen image is changed from the first orientation direction to the second orientation direction.

2. The mobile terminal of claim 1, wherein the modified mobile screen image is displayed on the first display unit despite that the orientation direction of the housing is not changed.

3. The mobile terminal of claim 1, wherein the mobile screen image and the monitor screen image share a content image related to a menu or application executed in the mobile terminal.

4. The mobile terminal of claim 1, wherein the mobile terminal further includes a wireless communication unit to interface with the external display device.

5. The mobile terminal of claim 1, wherein the mobile terminal further includes a wired data port to interface with the external display device.

6. The mobile terminal of claim 1, wherein the mobile terminal further includes a sensing unit configured to sense the orientation direction of the housing.

7. A system, comprising:

a display device having a second display unit for displaying a monitor window for displaying a monitor screen image; and

a mobile terminal including a first display unit for displaying a mobile screen image and a controller, wherein the controller of the mobile terminal is configured to;

interface to the display device,

receive a control signal relating to a modification of the mobile screen image from the display device, wherein a housing of the mobile terminal is in a first orientation direction,

control the mobile screen image to be modified in response to the control signal, even though the first orientation direction of the housing of the mobile terminal is not changed into a second orientation direction, and

provide a modified mobile screen image to the display device,

wherein the display device maintains the monitor window in the first orientation direction, even though an orientation direction of the mobile screen image is changed from the first orientation direction to the second orientation direction.

8. The system of claim 7, wherein the modified mobile screen image is displayed on the first display unit despite that the orientation direction of the housing is not changed.

9. The system of claim 7, wherein the mobile screen image and the monitor screen image share a content image related to a menu or application executed in the mobile terminal.

10. The system of claim 7, wherein the mobile terminal and the display device are interfaced to each other through a wireless communication unit.

11. The system of claim 7, wherein the mobile terminal and the display device are interfaced to each other through a wired data port.

12. The system of claim 7, wherein the monitor window has a substantially identical shape to one face of the housing of the mobile terminal.

13. A method for displaying a mobile screen image in a mobile terminal, the method comprising:

interfacing to an external display device having a second display unit for displaying a monitor window for displaying a monitor screen image;

receiving a control signal relating to a modification of the mobile screen image from the external display device, wherein a housing of the mobile terminal is in a first orientation direction;

controlling the mobile screen image to be modified in response to the control signal, even though the first orientation direction of the housing of the mobile terminal is not changed into a second orientation direction; and

providing a modified mobile screen image to the external display device,

wherein the external display device maintains the monitor window in the first orientation direction, even though an orientation direction of the mobile screen image is changed from the first orientation direction to the second orientation direction.

14. The method of claim 13, further including:

displaying the modified mobile screen image on the first display unit of the mobile terminal despite that the orientation direction of the housing is not changed.

15. The method of claim 13, wherein the mobile screen image and the monitor screen image share a content image related to a menu or application executed in the mobile terminal.

16. The method of claim 13, wherein the interfacing to the external display device is through a wireless communication unit.

17. The method of claim 13, wherein the interfacing to the external display device is through a wired data port.
