It can be.

The display device 100 may rotate the display panel 110 when an event for rotating the display panel 110 occurs. Here, the event for rotating the display panel 110 rotates the display panel 110 through a button provided on the display device 100 or a button provided on a remote control device communicating with the display device 100. Examples include when a user command is input, when the resolution of an image being displayed on the display panel 110 is changed, or when a user terminal device communicating with the display device 100 is rotated. It is not limited.

Referring to FIGS. 1A to 1C , the display device 100 may include a display panel 110 and a body portion 20 . Here, the body part 20 is configured to support the display panel 110, and the display panel 110 can be coupled to the body part 20 and rotated based on the body part 20. For example, as shown in FIGS. 1A to 1C , the display panel 110 may be rotated based on the rotation center 10 of the body 20 .

According to an embodiment of the present disclosure, the display panel 110 may be rotated in a landscape posture or a portrait posture. Depending on embodiments, the landscape posture may be referred to as a first posture or a horizontal posture, and the portrait posture may be referred to as a second posture or a portrait posture.

Here, the landscape posture is a posture in which the horizontal length of the display panel 110 is longer than the vertical length, and the portrait posture is a posture in which the vertical length of the display panel 110 is longer than the horizontal length. can

For example, when a user command for rotating the display panel 110 is input while the display panel 110 is in the landscape posture as shown in FIG. 1A, the display device 100 rotates the display panel 110 counterclockwise. direction can be rotated.

In this case, the display panel 110 may go through the posture shown in FIG. 1B and become the portrait posture shown in FIG. 1C.

Alternatively, when a user command for rotating the display panel 110 is input while the display panel 110 is in a portrait posture as shown in FIG. 1C, the display device 100 rotates the display panel 110 clockwise. can make it

In this case, the display panel 110 may go through the posture shown in FIG. 1B and become the landscape posture shown in FIG. 1A.

Meanwhile, the embodiment in which the display panel 110 rotates is not limited to those shown in FIGS. 1A to 1C. For example, the display panel 110 may rotate clockwise from a landscape posture to become a portrait posture, or rotate counterclockwise from a portrait posture to become a landscape posture.

Further, in the foregoing, an example in which the display panel 110 rotates 90 degrees in a clockwise or counterclockwise direction to be in a portrait posture or a landscape posture has been exemplified, but embodiments of the present disclosure are not limited thereto. For example, the display panel 110 may be rotated 90 degrees counterclockwise or clockwise from a portrait posture to become a landscape posture, and may be further rotated by 90 degrees in the same direction from the landscape posture to become a portrait posture.

In addition, although the stand-type support 20 is shown in FIGS. 1A to 1C, according to embodiments, the support 20 may be a wall-mounted support that is fixed to one area of a wall and can be installed.

Meanwhile, the display device 100 may include a plurality of speakers to output multi-channel audio data.

For example, referring to FIG. 2 , the display device 100 according to an embodiment of the present disclosure includes a plurality of speakers (1, 2, 3, 4, 5, 6) arranged in a plurality of areas of the display panel 110. ) may be included. Here, the plurality of speakers may output a plurality of audio data corresponding to a plurality of channels to provide surround sound.

For example, in the landscape posture, the display device 100 outputs audio data of a first channel corresponding to the front left sound through the first speaker 1 and corresponds to the front right sound through the second speaker 2. The audio data of the second channel corresponding to the surround left sound is output through the third speaker 3, and the audio data of the third channel corresponding to the surround left sound is output through the fourth speaker 4, and the third channel corresponding to the surround right sound is output through the fourth speaker 4. 4-channel audio data is output, the 5th channel audio data corresponding to the center sound is output through the 5th speaker 5, and the 6th channel audio corresponding to the center sound is output through the 6th speaker 6 data can be output.

Therefore, even if the display panel 100 is rotated from the portrait posture to the landscape posture, the first to sixth speakers 1, 2, 3, 4, 5, and 6 are rotated as in the above-described landscape posture. If the audio data of the first to sixth channels are output through a plurality of speakers, sound image localization is not achieved due to the arrangement change of the plurality of speakers, and the plurality of audio data with the overall acoustic balance broken is output through the plurality of speakers.

For example, as shown in FIG. 3 , even though the display panel 100 is rotated from the landscape posture to the portrait posture, as in the landscape posture, audio of the first channel corresponding to the front left sound through the first speaker 1 Data is PEQ set and output according to the first PEQ information corresponding to the front left sound, and audio data of the second channel corresponding to the front right sound is output through the second speaker 2 to the second PEQ corresponding to the front right sound. PEQ is set and output according to the information, and audio data of the third channel corresponding to the surround left sound through the third speaker 3 is PEQ set and output according to the third PEQ information corresponding to the surround left sound, and the fourth This is the case when the audio data of the fourth channel corresponding to the surround right sound is output through the speaker 4 after being PEQ set according to the fourth PEQ information corresponding to the surround right sound.

To solve this problem, the display device 100 of the present disclosure may set channels and PEQ of audio data output through a plurality of speakers based on the attitude of the display panel 100 . This will be described in detail with reference to FIG. 4 below.
