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 configured to process an image signal and an audio signal;

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

a speaker on a rear side of the display apparatus, the speaker being configured to output a sound wave corresponding to the audio signal processed by the signal processor;

a storage unit configured to store predetermined sound adjustment values;

a user interface (UI) generator configured to generate a UI for a user to select an installation condition of the display unit, the UI being displayed on the display unit, providing a plurality of selection options, for the installation condition selection, including a desktop type and a wall-mounted type;

a proximity sensor configured to sense a distance between the display apparatus and a wall; and

a controller configured to;

in response to the proximity sensor sensing the distance between the display apparatus and the wall, compare the sensed distance with a preset default, and determine, using the compared result, whether the installation condition of the display apparatus is the desktop type or the wall-mounted type;

in response to the installation condition being selected using the UI, determine, using the selected installation condition, whether the installation condition of the display apparatus is the desktop type or the wall-mounted type;

control, in response to determining that the installation condition of the display apparatus is the desktop type, the signal processor to adjust the sound wave of the speaker using a predetermined sound adjustment value for the desktop type stored in the storage unit; and

control, in response to determining that the installation condition of the display apparatus is the wall-mounted type, the signal processor to adjust the sound wave of the speaker using a predetermined sound adjustment value for the wall-mounted type stored in the storage unit.

2. The display apparatus according to claim 1, wherein the signal processor further comprises a frequency adjuster configured to adjust a frequency of the audio signal based on the adjustment value stored in the storage unit.

3. The display apparatus according to claim 1, wherein the controller is further configured to control the signal processor to adjust a frequency of the audio signal based on the adjustment value stored in the storage unit.

4. The display apparatus according to claim 1, further comprising a user input unit, wherein the controller is further configured to control the signal processor to adjust the sound wave to the adjustment value in response to a signal corresponding to the installation condition of the display apparatus being received through the user input unit.

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

a user input unit, wherein the controller is further configured to control 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.

6. The display apparatus according to claim 1, further comprising a rear side cover configured to accommodate the display unit therein.

7. The display apparatus according to claim 6, wherein the signal processor, the speaker, and the controller are provided in the rear side of the display unit, and accommodated by the rear side cover.

8. The display apparatus according to claim 6, further comprising a supporting casing configured to accommodate therein the signal processor, the speaker and the controller separately from the display unit.

9. The display apparatus according to claim 8, further comprising a supporter configured to be supported by the supporting casing, 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 connected to the supporting casing and the display unit through the supporter.

10. The display apparatus according to claim 8, wherein the supporting casing is configured to detachably connect to an external side of the rear side cover and electrically connect to the display unit to install the display apparatus on a horizontal surface.

11. The display apparatus according to claim 8, wherein the supporting casing comprises a supporting connector configured to be 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 configured to be exposed and formed from an external side of the display unit and connected to the supporting connector.

12. The display apparatus according to claim 11, further comprising a supporter configured to be supported by the supporting casing and attached to the display unit, and

the supporter comprises a connector configured to connect the supporting connector and the display connector.

13. The display apparatus according to claim 12, wherein the controller is further configured to determine whether the supporting connector is directly connected to the display connector or connected to the display connector through the connector, and to confirm the installation condition of the display apparatus.

14. The display apparatus according to claim 13, wherein, in response to the supporting connector being directly connected to the display connector, a high signal is applied to the controller, and the controller confirms that the display apparatus is installed on a vertical surface.

15. The display apparatus according to claim 13, wherein, in response to the supporting connector being is connected to the display connector through the connector, a low signal is applied to the controller and the controller confirms that the display apparatus is installed on a horizontal surface.

16. 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;

generating a UI for a user to select an installation condition of the display apparatus, the UI being displayed on a display unit of the display apparatus and providing a plurality of selection options for the installation condition selection including a desktop type and a wall-mounted type;

receiving through the generated UI a selection corresponding to the installation condition of the display unit;

sensing a distance between the display apparatus and a wall;

comparing the sensed distance between the display apparatus and the wall with a preset default;

determining whether the display apparatus is the desktop type of the wall-mounted type based on the compared result; and

adjusting a sound wave of a speaker provided on a rear side of the display apparatus using a predetermined sound adjustment value according to the determined result, wherein

in response to the display apparatus being determined to be the desktop type, the sound wave of the speaker is adjusted using a predetermined sound adjustment value for the desktop type, and in response to the display apparatus being determined to be the wall-mounted type, the sound wave of the speaker is adjusted using a predetermined sound adjustment value for the wall-mounted type; and
