Abstract

A display apparatus including a speaker and a control method thereof which controls the speaker to output a sound wave adjusted according to an installation condition of the display apparatus. The display apparatus includes a signal processor which processes an image signal and an audio signal; a display unit which displays an image corresponding to the image signal processed by the signal processor; a speaker which outputs a sound wave corresponding to the audio signal processed by the signal processor; and a controller which controls the signal processor to adjust the sound wave corresponding to the audio signal to an adjustment value according to an installation condition of the display apparatus.

Claims

1. A display apparatus comprising:

a signal processor which processes an image signal and an audio signal;

a display unit which displays an image corresponding to the image signal processed by the signal processor;

a speaker which outputs a sound wave corresponding to the audio signal processed by the signal processor; and

a controller which controls the signal processor to adjust the sound wave corresponding to the audio signal to an adjustment value according to an installation condition of the display apparatus.

2. The display apparatus according to claim 1, further comprising a storage unit which stores the adjustment value.

3. The display apparatus according to claim 2, wherein the signal processor further comprises a frequency adjuster which adjusts a frequency of the audio signal based on the adjustment value stored in the storage unit.

4. The display apparatus according to claim 2, wherein the controller controls the signal processor to adjust a frequency of the audio signal based on the adjustment value stored in the storage unit.

5. The display apparatus according to claim 1, further comprising a user input unit, wherein the controller controls the signal processor to adjust the sound wave to the adjustment value if a signal corresponding to the installation condition of the display apparatus is received through the user input unit.

6. The display apparatus according to claim 1, further comprising:

a user input unit; and

a user interface (UI) generator which generates a UI to display the installation condition of the display apparatus,

wherein the controller controls the UI generator to display the UI on the display unit, and controls the signal processor to adjust the sound wave to the adjustment value according to a selection from the displayed UI received through the user input unit.

7. The display apparatus according to claim 1, further comprising a rear side cover which accommodates the display unit therein.

8. The display apparatus according to claim 7, wherein signal processor, speaker and controller are provided in a rear side of the display unit, and accommodated by the rear side cover.

9. The display apparatus according to claim 7, further comprising a supporting casing which accommodates therein the signal processor, the speaker and the controller separately from the display unit.

10. The display apparatus according to claim 9, further comprising a supporter which is supported by the supporting casing and attached to at least one of the rear side cover and the display unit to install the display apparatus on a horizontal surface, and electrically connects the supporting casing and the display unit through the supporter.

11. The display apparatus according to claim 9, wherein the supporting casing is detachably connected to an external side of the rear side cover and electrically connected to the display unit to install the display apparatus on a horizontal surface.

12. The display apparatus according to claim 9, wherein the supporting casing comprises a supporting connector which is exposed and formed from an external side of the supporting casing and electrically connected to the display unit, and the display unit comprises a display connector which is exposed and formed from an external side of the display unit and connected to the supporting connector.

13. The display apparatus according to claim 12, further comprising a supporter which is supported by the supporting casing and attached to the display unit, and

the supporter comprises a connector which connects the supporting connector and the display connector.

14. The display apparatus according to claim 13, wherein the controller determines whether the supporting connector is directly connected to the display connector or connected to the display connector through the connector and confirms the installation condition of the display apparatus.

15. The display apparatus according to claim 14, wherein a high signal is applied to the controller if the supporting connector is directly connected to the display connector, and the controller confirms that the display apparatus is installed on a vertical surface.

16. The display apparatus according to claim 14, wherein a low signal is applied to the controller if the supporting connector is connected to the display connector through the connector, and the controller confirms that the display apparatus is installed on a horizontal surface.

17. A control method of a display apparatus which is installed on a horizontal surface or a vertical surface, the control method comprising:

receiving an image signal and an audio signal at the display apparatus;

determining an installation condition of the display apparatus;

processing the received audio signal according to the determined installation condition; and

outputting a sound wave corresponding to the processed audio signal.

18. The control method according to claim 17, wherein the processing the received audio signal comprising adjusting the sound wave corresponding to the audio signal to an adjustment value according to the installation condition of the display apparatus, wherein the adjustment value is prestored in the display apparatus.

19. The control method according to claim 17, wherein the determining the installation condition of the display apparatus comprises confirming reception of a signal corresponding to the installation condition of the display apparatus through a user input unit.

20. The control method according to claim 17, further comprising generating a user interface (UI) to display the installation condition of the display apparatus,

wherein the determining the installation condition of the display apparatus comprises confirming a selection from the generated UI which is received through the user input unit.
