Abstract

Disclosed is a display apparatus including: a display unit; a power supply unit which supplies power to at least one external device; and a controller which displays on the display unit an at least one indicating image indicating an at least one power supply area of the display unit supplying power to the at least one external device, and controls the power supply unit to supply power to the at least one external device placed on the at least one power supply area in a wireless manner.

Claims

1. A display apparatus comprising:

a display unit;

at least one power supply unit which supplies power to at lease one external device; and

a controller which displays on the display unit at least one indicating image indicating at least one power supply area of the display unit supplying power to the at least one external device, and controls the at least one power supply unit to supply power to the at least one external device placed on the at least one power supply area in a wireless manner.

2. The display apparatus according to claim 1, further comprising an external device detector which detects whether the at least one external device is placed on the at least one power supply area, wherein

the controller controls the power supply unit to supply power to the at least one external device if the external device detector detects the at least one external device and to stop power supply to the at least one external device.

3. The display apparatus according to claim 2, wherein the external device detector comprises a piezo electric sensor, an ultrasonic sensor or a photo sensor.

4. The display apparatus according to claim 1, further comprising a user input unit, wherein

the controller controls the display unit to display the at least one indicating image if a command is inputted through the user input unit.

5. The display apparatus according to claim 4, wherein the controller further displays a message related to the at least one indicating image if a different command is inputted through the user input unit.

6. The display apparatus according to claim 1, further comprising a user location detector which detects a location of a user with respect to the display apparatus, wherein

the controller displays a message related to the at least one indicating image on a part of the display unit adjacent to the location of the user detected by the user location detector.

7. The display apparatus according to claim 1, further comprising a touch detector which detects a touched location on the display unit, wherein

the controller displays the at least one indicating image if a command is inputted through the touch detector.

8. The display apparatus according to claim 7, wherein the controller controls the display unit to display a message related to the at least one indicating image on the touched location of the display unit.

9. The display apparatus according to claim 1, wherein the controller controls the display unit to stop displaying the at least one indicating image if it is determined that power supply to the external device is completed.

10. The display apparatus according to claim 1, wherein a displaying side of the display unit is arranged to be opposite to an installation surface of the display apparatus.

11. A control method of a display apparatus, the control method comprising:

displaying on a display unit at least one indicating image indicating at least one power supply area of the display unit which is capable of supplying power to at lease one external device; and

supplying power to the at least one external device placed on the at least one power supply area in a wireless manner.

12. The control method according to claim 11, wherein the supplying power to the at least one external device in a wireless manner comprises detecting whether the at least one external device is placed on the at least one power supply area;

and

supplying power to the at least one external device if the at least one external device is detected.

13. The control method according to claim 11, wherein the displaying the at least one indicating image on the display unit comprises receiving a command;

and

displaying the at least one indicating image corresponding to the command.

14. The control method according to claim 13, wherein the displaying the at least one indicating image corresponding to the command comprises displaying a message related to the at least one indicating image.

15. The control method according to claim 14, wherein the displaying the message related to the at least one indicating image comprises detecting a location of a user with respect to the display apparatus inputting the command;

and

displaying the message on a part of the display unit adjacent to the detected location of the user.

16. The control method according to claim 13, wherein the inputting the command comprises touching the display unit.

17. The control method according to claim 16, wherein the displaying the at least one indicating image on the display unit further comprises detecting a touched location of the display unit;

and

displaying a message related to the at least one indicating image on the detected location of the display unit.

18. The control method according to claim 11, wherein the supplying power to the at least one external device in a wireless manner comprises suspending the display of the at least one indicating image on the display unit if it is determined that the power supply to the at least one external device is completed.
