Method of providing external device list and image display device

1. A method of providing an external device list to an image display device, the method comprising:

displaying, via a display of the image display device, a plurality of external device icons including a first external device icon corresponding to a first external device connectable to the image display device via a first external interface and a second external device icon corresponding to a second external device connectable to the image display device via a second external interface, wherein the first external device icon includes a first default image and the second external device icon includes a second default image;

changing, via a controller of the image display device, the first default image to a first image based on a first image signal input from the first external device in response to the first external device icon being selected if the first external device is connected to the image display device, wherein the first image is displayed at a position corresponding to an area where the first external device icon is displayed, and

changing, via the controller, the second default image to a second image based on a second image signal input from the second external device in response to the second external device icon being selected if the second external device is connected to the image display device, wherein the second image is displayed at a position corresponding to an area where the second external device icon is displayed.

2. The method according to claim 1 , wherein the first external device icon is highlighted in response to the first external device icon being selected and the second external device icon is highlighted in response to the second external device icon being selected.

3. The method according to claim 1 , further comprising:

displaying, via the display, a third external device icon corresponding to a third external device connectable to the image display device via a third external interface, wherein the third external device icon includes a third default image; and

changing, via the controller, the third default image to a third image based on a third image signal input from the third external device in response to the third external device icon being selected if the third external device is connected to the image display device, wherein the third image is displayed at a position corresponding to an area where the third external device icon is displayed.

4. The method according to claim 1 , further comprising:

transmitting a control command for controlling the first external device to the first external device; and

displaying an execution result of the control command on the display of the image display device in response to the control command.

5. An image display device comprising:

a display;

a first external interface configured to receive a first image signal input from a first external device connected to the image display device;

a second external interface configured to receive a second image signal input from a second external device connected to the image display device;

a controller coupled with the display, the first external interface and the second external interface, the controller configured to:

display a plurality of external device icons including a first external device icon corresponding to the first external device and a second external device icon corresponding the second external device, wherein the first external device icon includes a first default image and the second external device icon includes a second default image,

change the first default image to a first image based on the first image signal in response to the first external device icon being selected if the first external device is connected to the image display device, wherein the first image is displayed at a position corresponding to an area where the first external device icon is displayed, and

change the second default image to a second image based on the second image signal in response to the second external device icon being selected if the second external device is connected to the image display device, wherein the second image is displayed at a position corresponding to an area where the second external device icon is displayed.

6. The image display device according to claim 5 , wherein the controller is further configured to:

highlight the first external device icon in response to the first external device icon being selected, and

highlight the second external device icon in response to the second external device icon being selected.

7. The image display device according to claim 5 , further comprising:

a third external interface configured to receive a third image signal input from a third external device connected to the image display device,

wherein the controller is further configured to:

display a third external device icon corresponding to the third external device, wherein the third external device icon includes a third default image, and

change the third default image to a third image based on the third image signal in response to the third external device icon being selected if the third external device is connected to the image display device, wherein the third image is displayed at a position corresponding to an area where the third external device icon is displayed.

8. The image display device according to claim 5 , wherein the controller is further configured to:

transmit a control command for controlling the first external device to the first external device, and

display an execution result of the control command on the display.

9. The method according to claim 1 , wherein when the first or second external devices are connected to the image display device, the first or second external device icons are respectively displayed to be distinguished from when the first or second external devices are not connected to the image display device.

10. The image display device according to claim 5 , wherein when the first or second external devices are connected to the image display device, the first or second external device icons are respectively displayed to be distinguished from when the first or second external devices are not connected to the image display device.

11. The device according to claim 5 , wherein the first image is simultaneously displayed with the plurality of external device icons for a period of time.

12. The method according to claim 1 , wherein the first and second external device icons are selectable via a cursor positioned on the first and second external device icons, respectively.

13. The method according to claim 12 , wherein the cursor is controlled by a remote controller interfacing with the image display device.

14. The method according to claim 1 , wherein the first and second images are displayed in place of the first and second external device icons, respectively.

15. The image display device according to claim 5 , wherein the first and second external device icons are selectable via a cursor positioned on the first and second external device icons, respectively.

16. The image display device according to claim 15 , wherein the cursor is controlled by a remote controller interfacing with the image display device.

17. The image display device according to claim 5 , wherein the first and second images are displayed in place of the first and second external device icons, respectively.
