[0093] A plurality of microphones 290 may be provided.

[0094] Next, FIG. 4 will be described.

[0095] FIG. 4 illustrates an example of utilizing a remote control device 200 according to an embodiment of the present disclosure.

[0096] FIG. 4( a ) illustrates an example in which a pointer 205 corresponding to the remote control device 200 is displayed on the display 180 .

[0097] The user can move the remote control device 200 up and down, left and right, and rotate it. A pointer 205 displayed on the display 180 of the display device 100 corresponds to the movement of the remote control device 200. Such a remote control device 200 can be called a "space remote control" because the pointer 205 moves and is displayed according to the movement in the 3D space, as shown in the drawing.

[0098] FIG. 4(b) illustrates that when the user moves the remote control device 200 to the left, the pointer 205 displayed on the display 180 of the display device 100 also moves to the left correspondingly.

[0099] Information about the movement of the remote control device 200 sensed by a sensor of the remote control device 200 is transmitted to the display device 100. The display device 100 can calculate coordinates of the pointer 205 from the information about the movement of the remote control device 200. The display device 100 can display the pointer 205 according to the calculated coordinates.

[0100] 4(c) illustrates an example in which, while pressing a specific button on the remote control device 200, the user moves the remote control device 200 away from the display 180. As a result, the selected area on the display 180 corresponding to the pointer 205 is zoomed in and enlarged.

[0101] Conversely, when the user moves the remote control device 200 closer to the display 180, the selected area in the display 180 corresponding to the pointer 205 is zoomed out and displayed in a smaller size.

[0102] On the other hand, when the remote control device 200 moves away from the display 180, the selection area is zoomed out, and when the remote control device 200 moves closer to the display 180, the selection area is zoomed in.

[0103] Furthermore, when a specific button on the remote control device 200 is pressed, recognition of up / down and left / right movement is eliminated. That is, when the remote control device 200 moves toward or away from the display 180, up / down and left / right movement is not recognized, and only forward / backward movement is recognized. When a specific button on the remote control device 200 is not pressed, only the pointer 205 moves in accordance with the up / down and left / right movement of the remote control device 200.

[0104] On the other hand, the moving speed and direction of the pointer 205 can correspond to the moving speed and direction of the remote control device 200 .

[0105] Meanwhile, the pointer in this specification refers to an object displayed on the display 180 in response to the operation of the remote control device 200. Therefore, the pointer 205 can be an object of various shapes other than the arrow shape shown in the drawings. For example, it may be a concept including a point, a cursor, a prompt, a thick border, etc. The pointer 205 can be displayed corresponding to one point on the horizontal or vertical axis on the display 180, or can be displayed corresponding to multiple points such as a line or a surface.

[0106] Next, the display device 100 according to an embodiment of the present disclosure will be described in more detail.

[0107] FIG. 5 is a perspective view of a display device 100 according to an embodiment of the present disclosure.

[0108] FIG. 6 is a diagram illustrating the state of the display apparatus 100 according to the display operation mode according to an embodiment of the present disclosure.

[0109] FIG. 7 is a perspective view illustrating a configuration of a display and a lower case 520 therefor according to an embodiment of the present disclosure.

[0110] The display device 100 according to an embodiment of the present disclosure may be embodied in the shape of a box (or briefcase) containing a display, although this shape is merely an example and the present disclosure is not limited thereto.

[0111] A display device according to an embodiment of the present disclosure may include a first case accommodating at least one speaker and a second case accommodating a display. When the first case is detached from the second case, the first case can be opened at a predetermined angle and tilted. The second case may include a moving mechanism that supports movement of the display to any position. The moving mechanism may be mounted, for example, to a groove provided in the second case and to one surface of the display. The moving mechanism may be configured as a foldable stand that supports up / down, left / right, and / or rotational movement. At least one of the first case and the second case may include a processor that controls the output of the at least one speaker depending on the state of the display.

[0112] Referring to FIG. 5, the display device 100 may be composed of an upper case 510 and a lower case 520 .

[0113] In this specification, the term "case" may be substituted with terms such as "box" or "housing," but is not limited thereto. The upper case may be expressed as, for example, an upper box or an upper housing. However, for convenience of explanation, it will be referred to as "case" hereinafter.

[0114] The upper case 510 and the lower case 520 constituting the display device 100 according to an embodiment of the present disclosure may be formed to have an openable and closable structure.

[0115] In this regard, for the sake of convenience, FIG. 5 shows the upper case 510 in an open state.

[0116] One side of the upper case 510 and one side of the corresponding lower case 520 may be coupled to each other by a first coupling means, which may include, but is not limited to, a hinge.

[0117] The other side of the upper case 510 and the corresponding other side of the lower case 520 can be connected and separated by a second connecting means. Unlike the first connecting means described above, the second connecting means may include a configuration in which the connecting force weakens and the connection is released when pressure is applied. When pressure is applied to the second connecting means, the upper case 510 is released from the lower case 520 and opened as shown in FIG. 5. The upper case 510 can be automatically opened by the first connecting means. The opening speed of the upper case 510 is adjusted by the first connecting means.

[0118] The second coupling means may be embodied, for example, by a latch-lock groove combination. The latch may be formed on the upper case 510. The lock groove may be formed on the lower case 520. The upper case 510 and the lower case 520 are coupled together by inserting the latch into the lock groove. When pressure is applied to the lock groove opening formed on the outer casing 560 of the lower case 520, the latch inserted into the lock groove is released from the lock groove. However, the second coupling means is not limited to the latch-lock groove combination.

[0119] 5, four grooves (not shown) are formed on the lower surface of the lower case 520. Each groove accommodates at least one rack 540 for supporting the display device 100.

[0120] Casters 550 are coupled to the other side of the racks 540 accommodated in the grooves of the lower case 520. The casters 550 can support the movement of the display device 100. Although four grooves, four racks, and four casters are illustrated in FIG. 5, the number of grooves, racks, and casters is not limited thereto. There is no limit to the number of grooves, racks, and casters as long as they support the movement of the display device 100.

[0121] Each rack 540 can be detachably attached to a corresponding groove formed on the lower surface of the lower case 520. Each rack 540 can be extended in the length direction. The racks 540 allow the height of the display device 100 to be adjusted.

[0122] The caster 550 may include wheels. The caster 550 may support the display apparatus 100 so that it can move in any direction by applying pressure through the wheels. The caster 550 may also include a fixing means for restricting the movement of the wheels. The fixing means may support the display apparatus 100 so that it is fixed in a predetermined position, for example, to prevent problems in viewing content due to unintentional movement of the display apparatus 100.

[0123] The upper case 510 and the lower case 520 may each have a predetermined thickness. A strap (handle) 530 may be provided on the outer surface of at least one of the upper case 510 and the lower case 520. Although FIG. 5 illustrates an example in which the strap 530 is formed on the outer surface of the lower case 520, the present invention is not limited thereto. A user can move the display device 100 to a desired position using the strap 530.

[0124] Hereinafter, the operation of the display apparatus 100 shown in FIG. 5 will be described in more detail.

[0125] 5, the upper case 510 may be provided with at least one audio output means such as a speaker, and the lower case 520 may be provided with a display 610, but is not limited thereto.

[0126] The display 610 described herein is generally embodied in a rectangular shape, but is not limited thereto. The rectangular shape may include a rectangular shape as a whole or a shape in which each vertex is rounded.

[0127] The display device 100 may include at least one speaker, a display, and a processor that controls the at least one speaker and the display. The processor may control the output of the at least one speaker based on relationship information between the at least one speaker and the display. The relationship information is obtained from a physical relationship between the display and the at least one speaker when the display is moved to an arbitrary position by a movement mechanism. The movement mechanism may be coupled to one side of the display.

[0128] The movement mechanism may include, but is not limited to, a folding stand or may be configured to operate by the folding stand. The folding stand may include at least one hinge. The display device 100 may further include at least one sensor that senses the position of the display moved by the movement mechanism. The at least one sensor may be attached to or built into one surface of the display.

[0129] The physical relationship between the display and the at least one speaker may be defined according to the degree of overlap with the output direction of the at least one speaker depending on the position of the moved display. The physical relationship between the display and the at least one speaker may be defined by the distance between the moved display and the at least one speaker. The physical relationship between the display and the at least one speaker may be defined by the degree of overlap with the output direction of the at least one speaker depending on the position of the moved display and the distance between the display and the at least one speaker, but is not limited to this.

[0130] The processor can define an operating mode for the display based on relationship information according to a physical relationship between the display and the at least one speaker.

[0131] The operating modes of the display may include at least one of a first operating mode in which there is no overlap with the output direction of at least one speaker, a second operating mode in which there is full overlap with the output direction of at least one speaker, and a third operating mode in which there is partial overlap with the output direction of at least one speaker, but are not limited to these.

[0132] The processor may define an output of the at least one speaker in the first operating mode as a reference output, and the processor may control the output of the at least one speaker in the remaining operating modes but not in the first operating mode based on the reference output.

[0133] When the display operates in the second operating mode, the processor can control the output of the at least one speaker to decrease the output in the first frequency band and increase the output in the second frequency band compared to the reference output.

[0134] When the display operates in the third operating mode, the processor can control the output of the at least one speaker to decrease the output in the third frequency band and increase the output in the fourth frequency band compared to the reference output.

[0135] When the display operates in the third operating mode, the processor can control the output of the fifth frequency band to be lowered and the output of the sixth frequency band to be higher compared to the output of the at least one speaker in the second operating mode.

[0136] The processor can control the output of the at least one speaker according to the operation mode of the display determined based on the relationship information and the mapped EQ mode.

[0137] When the at least one speaker is implemented in an array form, the processor may control an output direction of the at least one speaker according to an operation mode determined based on the relationship information.

[0138] More specifically, the operation modes of the display device 100 will be described as follows.

[0139] In addition to the definitions of the operation modes described above, the operation modes may be defined based on the relationship between the display 610 and the lower case 520. The operation modes may be defined based on the relationship between the display 610 and the upper case 510. The operation modes may be defined based on the relationship between the display 610, the upper case 510, and the lower case 520, but are not limited to this.

[0140] The operation mode may be substituted by various terms such as a screen mode, a playback mode, an output mode, or a display state.

[0141] As mentioned above, three operation modes are illustrated in FIG.

[0142] In the description of the operation mode, it is assumed that the upper case 510 is opened so that the display 610 connected to the lower case 520 can be exposed to the outside. Here, "exposed to the outside" may refer to a state in which, for example, when content is played through the display, the user can view the content.

[0143] The opened upper case 510 may be fixed at a position where an arbitrary angle is formed between it and the lower case 520. Here, the arbitrary angle may be determined by settings or user selection. The arbitrary angle may represent, for example, an angle between the upper case 510 and the lower case 520 (or a reference plane such as a floor plane) between 90 degrees and 270 degrees, but is not limited thereto.

[0144] The first operational mode may represent a state in which the display 610 is fixed to the lower case 520 (or parallel to the lower case) as shown in Figure 6(a). Thus, in the first operational mode, the display 610 is parallel to the lower case 520 but forms an arbitrary angle (e.g., 90 degrees) with the upper case 510. The first operational mode may also be referred to as a turntable operational mode, a basic or default operational mode, etc.

[0145] When not in the first operating mode, the display 610 may indicate a state in which the display 610 is not fixed to the lower case 520, i.e., an unlocked state. In this sense, the first operating mode may be referred to as a fixed mode, and when not in the first operating mode, it may be referred to as an unlocked mode or an unlocked mode.

[0146] The release mode may include, but is not limited to, a second operation mode as shown in Fig. 6(b) and a third operation mode as shown in Fig. 6(c).

[0147] 6(b) and 6(c), the second and third operating modes may represent states in which the display 610 is released from the lower case 520 and fixed at an arbitrary position. The arbitrary position may represent, for example, a position in which an arbitrary angle is formed between the lower case 520 or a reference plane and the display 610. The arbitrary angle may represent, but is not limited to, a range of 1 to 180 degrees.

[0148] Alternatively, as described above, if the display 610 is disposed on the front surface of the upper case 510 and overlaps at least a portion of the upper case 510 when viewed from the front, the degree of overlap can be defined as a second operating mode (overlap equal to or greater than a reference value) or a third operating mode (overlap less than a reference value).

[0149] Alternatively, when the display device 100 is viewed from the side, the case in which the display 610 and the upper case 510 are parallel (or nearly parallel) with a predetermined gap between them can be defined as the second or third operation mode.

[0150] The second operating mode may represent a case where the display 610 is disposed in front of the upper case 510 and the display 610 and the upper case 510 overlap each other by a reference value or more when the display device 100 is viewed from the front. The second operating mode may be called a landscape mode or a horizontal mode, in distinction from a third operating mode described below.

[0151] When the display device 100 is in the second operation mode, the audio output from the speaker provided in the upper case 510 is interrupted by the display 610 disposed in front, and therefore, control of the audio output is required.

[0152] The second operating mode may be defined as a mode in which content is played back in a state where the display 610 is long horizontally and short vertically, like a typical rectangular display, as shown in (b) of Figure 6. Meanwhile, the third operating mode may be defined as a mode in which content is played back in a state where the display 610 in the second operating mode is rotated about a vertical axis relative to the lower case 520, i.e., where the display is short horizontally and long vertically, as shown in (c) of Figure 6. In this sense, the third operating mode may be distinguished from the second operating mode and referred to as a portrait mode or a portrait mode.

[0153] The rotation angle is, for example, 90 degrees as shown in FIG. 6(c), but is not limited to this.

[0154] As mentioned above, the third operating mode can be defined as simply when the display 610 is rotated by a predetermined angle in the second operating mode, but it can also be defined to represent all cases that are not the first or second operating modes.

[0155] The third operating mode may include not only the case where the display 610 is rotated by an arbitrary angle in the second operating mode, but also the case where the angle formed with the lower case 520 or the reference plane (or the angle formed with the upper case 510) is an arbitrary angle different from that in the second operating mode. However, for convenience of explanation, the case of (c) of FIG. 6 will be described as the third operating mode as an example.

[0156] FIG. 7 illustrates the structure of display device 100 for supporting movement of display 610 in relation to display operating modes.

[0157] For convenience of explanation, only the lower case 520 and the display 610 are shown in Fig. 7. Fig. 7 shows a perspective view in which the rear surface of the display 610 is exposed to explain the state changes of the display 610 according to the operation mode.

[0158] Referring to FIG. 7, a base (or stand base) 710 may be provided inside the lower case 520.

[0159] The base 710 is formed to have a predetermined thickness or height so that the display 610 can be accommodated or seated thereon.

[0160] The base 710 is formed with at least one recess 715, 716. A mechanism is mounted or accommodated in the first recess 715. The mechanism may include a foldable stand (or base, lever, etc.) 720. The second recess 716 accommodates the remote control device 200. The depth of each recess 715, 716 is determined by the foldable stand 720, the remote control device 200, etc.

[0161] The base 710 may be provided with a separate fixing means or coupling means (not shown) to fix or couple a structure provided at the lower end of the rear surface of the display 610. The base 710 may identify whether the display 610 is fixed or coupled to the lower case 520. The fixing means or coupling means may include, for example, a structure or configuration that is fixed or coupled when a predetermined pressure is applied.

[0162] The folding stand 720 is attached so as to be in direct contact with the rear surface of the display 610. The folding stand 720 can be coupled to a mounter 730 provided on the rear surface of the display 610. The folding stand 720 can support the movement of the display 610, i.e., can move and fix it to any position.

[0163] The mechanism may be embodied in a folding manner using a structure such as a hinge 725 to support movement of the display 610 to any angle (or any position), such as up and down, left and right, but is not limited thereto.

[0164] The foldable stand 720 may include a first stand part attached or fixed to the receiving groove 715 and a second stand part connected to a mounter 730 formed on the rear surface of the display 610. The first stand part and the second stand part are connected by a hinge 725 and can move at any angle. The first stand part can support the second stand part.

[0165] A plurality of hinges may be used depending on the shape of the folding stand. For convenience, a hinge for supporting up-and-down movement of the display 610 is disclosed in FIG. 7, but the present invention is not limited to this. A separate hinge for supporting left-and-right movement of the display 610 may be provided. A single hinge may support both up-and-down and left-and-right movement of the display 610. Such a hinge may include a pivot hinge.

[0166] A connector (or coupler) 735 having a structure or shape for coupling with the mounter 730 is attached to the other side of the folding stand 720 (e.g., one side of the second stand). The connector 735 may have a structure or shape that can be coupled with the mounter 730 to support not only up-down and left-right movements of the display 610 but also rotational movements.

[0167] 7, i.e., through at least one of the support parts, i.e., the folding stand 720, the hinge 725, the mount 730, and the connector 735, not only as shown in (b) and (c) of FIG. 6, but also after the display 610 is released from the lower case 520, it can be tilted at any angle from the lower case 520 (or a reference plane) or moved to any position and fixed.

[0168] The display apparatus 100 may adjust and control the output of at least one speaker provided in the upper case 510 based on relationship information between the at least one speaker and the display 610 connected to the lower case 520 .

[0169] In the above, the related information may represent the above-mentioned operation mode, but is not limited to this.

[0170] In the first operating mode, i.e., the basic operating mode, shown in FIG. 6(a), the display 610 blocks the speaker output or has no effect on the output. In contrast, in the second and third operating modes, shown in FIG. 6(b) and (c), the display 610 is positioned in front of the speaker output direction, blocking or affecting all or part of the speaker output. Therefore, in the latter case, the user can sense a change in sound through the speaker. In the case of the relationship between the display 610 and speaker shown in FIG. 6(b) and (c), the display 610 is positioned in front of the speaker output direction, and acts like an obstacle due to the positional relationship between the two components, which can cause phenomena such as sound reflection, diffraction, transmission, and sound absorption. Therefore, even if there is no change in the speaker output in operating modes other than the basic operating mode, the user may feel as if the speaker output has changed (e.g., a deterioration in sound quality), resulting in inconvenience.

[0171] FIG. 8 is a block diagram of a display device 100 according to another embodiment of the present disclosure.

[0172] 8 illustrates and describes only the configuration related to adjusting or controlling the speaker output according to the operation mode of the display, but is not limited thereto. If necessary, one or more components illustrated in FIG. 1 may be further included.

[0173] Referring to FIG. 8, the display device 100 includes a memory 140, a receiving unit 810, a sensor unit 820, a controller 170, a video processing unit 830, and an audio processing unit 840.

[0174] The memory 140 can store information and data received or generated by the display device 100 .

[0175] The memory 140 may store control content associated with each operation mode of the display device 100 shown in Figures 6(a) to 6(c). The stored control content may include preset audio output control content associated with each operation mode (e.g., preset information on the characteristics of the display 610 and the output characteristics of the speaker in the first to third operation modes). Meanwhile, the mapping may be configured in the form of a table.

[0176] The display apparatus 100 may refer to the mapped control content when controlling according to the operation mode, or may automatically apply the control content like a macro function in the identified operation mode based on the mapped control content.

[0177] When the operation mode is changed to the third operation mode, the content being provided through the display 610 in the second operation mode is rotated in a certain direction to match the display (i.e., rotated in the second operation mode) in the third operation mode and output, and a preset value is applied to match the speaker output in the third operation mode. Compared to the second operation mode, the display 610 does not completely block or completely shut off the speaker output in the third operation mode. Therefore, different values ​​or methods are applied to the audio control in the second operation mode, which completely overlaps with the speaker output direction and completely blocks or shuts off the sound, and the audio control in the third operation mode.

[0178] The memory 140 can also map and store data on settings input by a user or automatically determined or set display and speaker output adjustments according to a display fixed at an arbitrary position. The memory 140 can receive user feedback data on table information values ​​via a receiving unit 810 (described later) and update already mapped information.

[0179] The receiving unit 810 may receive a user input to the display apparatus 100. The receiving unit 810 may have the same configuration as the user input interface 150 of FIG. 1 or may be a separate configuration. The user input may include a touch input if the display 610 employs a touch screen. If the display 610 does not employ a touch screen, the user input may include an IR input via the remote control device 200 (or a mobile terminal linked to the display apparatus 100) shown in FIGS. 2 to 4. The user input may also include a voice input via an AI speaker linked to the display apparatus 100 or a gesture input via a wearable device. Of course, the user input may be a combination of the above-mentioned inputs, and the receiving unit 810 may process a signal corresponding to the above-mentioned input or a combination of inputs.

[0180] The sensor unit 820 can sense the movement of the display 610 .

[0181] For motion sensing of the display 610, an acceleration sensor as shown in Fig. 8(b) or a gyro sensor as shown in Fig. 8(c) may be included, but this is merely an example and is not limited thereto.

[0182] 8(b), the sensor unit 820 can sense the gravitational acceleration using an acceleration sensor to obtain a value of -G in each axis direction, where G represents a unit of acceleration where 1G is the same value as the standard gravitational acceleration.

[0183] The acceleration sensor according to the present disclosure can process the movement of the display 610, i.e., the operation mode of the display device 100, as follows.

[0184] [Table 1]

[0185] 8(c), the gyro sensor may be, for example, a 6-axis gyro sensor incorporating an acceleration sensor that senses three-axis values ​​of speed and acceleration per second, but is not limited thereto. The sensor unit 820 may further sense how much the X, Y, and Z axes have rotated per time unit by the gyro sensor.

[0186] The controller 170 can read the movement data of the display 610, that is, the X, Y, and Z axis coordinate value data, from the sensor unit 820 to identify the operation mode of the display.

[0187] The controller 170 may identify the operation mode of the display in real time based on the movement data (X-, Y-, and Z-axis coordinate value data) of the display 610 received by the sensor unit 820, and perform control according to the identified operation mode of the display. Such control according to the operation mode may include, for example, adjusting and controlling the output of at least one speaker by the audio processing unit 840, or controlling the operation of the video and audio processing units 830 and 840 with respect to the content output via the display 610.

[0188] When the sensor unit 820 receives movement data of the display 610, the controller 170 can determine the operation mode of the display 610 only if the movement data corresponds to a predetermined reference value (e.g., based on an absolute value). When the sensor unit 820 receives movement data of the display 610, the controller 170 can determine the operation mode of the display 610 only if the movement data is equal to or greater than a predetermined reference value (e.g., based on a relative value (difference)). The controller 170 can appropriately control the output of the speaker according to the determined operation mode.

[0189] Meanwhile, even if the movement data of the display 610 is received from the sensor unit 820, if the movement data does not correspond to a predetermined reference value (e.g., based on an absolute value) or is less than the predetermined reference value (e.g., based on a relative value (difference)), the controller 170 may not need to separately determine the operation mode of the display 610. Nevertheless, if a table mapping the control level of the speaker output compared to the reference value already exists, the controller 170 may control the output of the currently applied speaker based on the value mapped in the table.

[0190] When sensing data is collected by the sensor unit 820, the controller 170 may analyze the collected sensing data.

[0191] Alternatively, the controller 170 may periodically or irregularly collect sensing data using the sensor unit 820. The controller 170 may periodically or irregularly analyze the collected sensing data.

[0192] Meanwhile, the controller 170 can acquire relationship information (e.g., angle information) formed between the upper case 510 and the lower case 520 from the sensing data collected by the sensor unit 820. The controller 170 can analyze the acquired relationship information, i.e., the collected sensing data only when the angle formed between the upper case 510 and the lower case 520 is equal to or greater than a critical value.

[0193] The video processor 830 may process video data constituting content differently depending on the operation mode of the display 610. For example, the video processor 830 may process and output video data at a lower resolution than the resolution of the original data (e.g., 4K resolution to Full-HD resolution) in the first or third operation mode under the control of the controller 170, since the importance of video may be relatively low (e.g., data mainly consisting of still images or text rather than video data). This not only reduces the power consumption of the display device 100, but also increases the data processing speed and efficiently utilizes resources by providing Full-HD resolution video data rather than ultra-high resolution video data. Meanwhile, in the second operation mode, the importance of video output is relatively higher than in other operation modes, so the video resolution of the original content may be further increased. However, the above content is merely an example, and the present disclosure is not limited to this example.

[0194] The audio processor 840 may process audio data constituting content differently depending on the operation mode of the display, for example. For example, under the control of the controller 170, the audio processor 840 may process the audio data so that sound is output in a first EQ mode (basic mode) in a first operation mode.

[0195] Meanwhile, the audio processing unit 840 may process audio data to be served in the second EQ mode in the second operation mode under the control of the controller 170. Also, the audio processing unit 840 may process audio data to be served in the third EQ mode in the third operation mode under the control of the controller 170. Thus, the display apparatus 100 may control the output of video and / or audio in a customized manner according to the identified display operation mode, thereby outputting content.

[0196] The operation of the audio processor 830 will be described in more detail below.

[0197] FIG. 9 is a flowchart illustrating an audio data processing method according to an embodiment of the present disclosure.

[0198] FIG. 10 is a flowchart illustrating an audio data processing method according to another embodiment of the present disclosure.

[0199] 11a to 11c and 12a to 12c are diagrams illustrating a method for processing audio data according to each display operation mode according to an embodiment of the present disclosure.

[0200] Referring to FIG. 9, when the display device 100 is turned on (S101), the controller 170 can receive a user input (S103).

[0201] In the above, "turned on" may indicate, for example, a state in which power is supplied to the display apparatus 100. Meanwhile, even if power is supplied to the display apparatus 100, if the display apparatus 100 is not in a content output ready state in the first to third operation modes as shown in Fig. 6, that is, if the upper case 510 is not opened or the display is not exposed to the outside, it may be determined that the display apparatus 100 is not in a turned on state.

[0202] When the display apparatus 100 closes the upper case 510 without transmitting or selecting an end input during content playback in the first to third operation modes according to the user's selection or setting, the display apparatus 100 can output the content (in this case, the video is turned off and only audio is output to reduce power consumption) for at least a predetermined time. In this case, the content is excluded by the above-mentioned turn-on.

[0203] The user input receiving process may be omitted or may be replaced by the user moving the display 610 in space at will. For example, if the user directly fixes the display 610 in a desired position rather than via the remote control device 200, the detected operation mode change signal may be replaced by the user input. In this sense, step S103 may be omitted.

[0204] On the other hand, the display device 100 may directly select an operation mode by an input means such as a user's remote control device 200, in which case the display device 100 may automatically release the display 610 to match the selected operation mode, move it to a corresponding position, or vice versa.

[0205] In step S105, the sensor unit 820 can sense data regarding the operation mode of the display 610 using the sensors shown in (b) and (c) of Figure 8, and the controller 170 can obtain sensing data regarding the operation mode of the display 610 from the sensor unit 820.

[0206] In the present disclosure, the sensor unit 820 may be mounted on or built into the display 620.

[0207] Meanwhile, the sensor unit 820 can transmit the sensing value, i.e., raw data, obtained from the sensor directly to the controller 170. The sensor unit 820 can also convert the sensing value into relationship information according to the relationship between the upper case 510, the lower case 520, or the reference surface and the display 610 and transmit the information to the controller 170.

[0208] In step S107, the controller 170 may determine whether the display 610 is currently in the first operation mode by using the sensing data regarding the operation mode of the display 610 acquired in step S105.

[0209] When the display 610 is in the first operation mode, the controller 170 does not need to control the current output of the speaker, and therefore can control the content to be output as is without transmitting a separate control command.

[0210] On the other hand, in step S109, if the display 610 is not in the first operation mode as a result of the determination in step S107, the controller 170 may re-determine whether the display 610 is in the second operation mode.

[0211] In step S111, the controller 170 may transmit a first audio output control signal to the audio processor 840 if the display 610 is in the second operation mode as a result of the determination in step S109.

[0212] In step S113, if the display 610 is not in the second operation mode as a result of the determination in step S109, the controller 170 may determine that the display 610 is in the third operation mode and transmit a second audio output control signal to the audio processor 840. If there are additional operation modes, the controller 170 may further perform a process of determining whether each operation mode is in the corresponding operation mode.

[0213] In step S115, the controller 170 may control the display 610 to output content suitable for each operation mode.

[0214] Next, an example of audio output control will be described with reference to Fig. 10. In particular, in Fig. 10, when the first operation mode is determined, there is no need to perform any particular audio control, so the description will be given assuming the second and third operation modes.

[0215] In step S201, the controller 170 may determine the operation mode of the display device 100.

[0216] A first EQ mode (not shown) may represent the EQ mode originally applied in the first operating mode.

[0217] In step S203, the controller 170 may determine to apply a second EQ mode if the determination result in step S201 indicates the second operation mode. The second EQ mode value may be a value obtained by changing at least a part of the value of the first EQ mode.

[0218] In step S205, the controller 170 may determine to apply a third EQ mode if the determination result in step S201 is not the second operation mode. The value of the third EQ mode may be different from the value of the first EQ mode or the value of the second EQ mode, and may be a value obtained by changing at least a part of the value of the first EQ mode (or the value of the second EQ mode).

[0219] In step S207, the controller 170 may determine whether to perform a write operation of an AMPEQ value corresponding to the EQ mode determined in step S203 or S205 when applying the EQ mode to the display device 100.

[0220] In step S209, if the AMPEQ value is not written in step S207, the controller 170 may perform a write operation on the corresponding AMPEQ value according to a user input or setting.

[0221] In step S211, the controller 170 may control the output of a sound according to the operation mode.

[0222] The EQ modes in FIGS. 9 and 10 will be described below with reference to FIGS.

[0223] As described above, the display apparatus 100 according to the present disclosure may include at least one speaker in the upper case 510. Hereinafter, a case where the upper case 510 of the display apparatus 100 includes two speakers will be described as an example, but the present disclosure is not limited thereto. One of the two speakers may be a full-range speaker that outputs audio in a relatively wide frequency band, and the other may be a tweeter speaker that outputs audio in a relatively narrow frequency band. The tweeter speaker may be responsible for audio output in a particularly high frequency band. However, this is merely an example and the present disclosure is not limited thereto.

[0224] 11 and 12 are graphs illustrating comparative explanations of control over the output of a full-range speaker and a tweeter speaker according to the operation mode of the display device 100, respectively.

[0225] 11 and 12 may represent the respective EQ modes described above, for example, Fig. 11a and Fig. 12a may represent the first EQ mode, Fig. 11b and Fig. 12b may represent the second EQ mode, and Fig. 11c and Fig. 12c may represent the third EQ mode.

[0226] First, the output of the full-range speaker in FIG. 11 will be explained.

[0227] 11a may be the output setting of the full-range speaker in the first operation mode, i.e., the first EQ mode content, of the display device 100. The first operation mode may be, for example, a case in which the display 610 is fixed to the lower case 520 as shown in FIG. 6(a) above. In this case, there is no overlap between the front of the upper case 510 on which the full-range speaker is provided (or built-in), i.e., the audio output direction of the full-range speaker, and the display. Therefore, the display does not obstruct or interfere with the audio output of the full-range speaker, and therefore no separate control of the audio output is required.

[0228] The output of the full-range speaker in Fig. 11a can be used as a reference for adjusting the speaker output in other operating modes. For ease of explanation, the output adjustment control of the full-range speaker according to each operating mode shown in the graphs of Figs. 11b and 11c will be described below in comparison with the full-range speaker output in the first operating mode (i.e., first EQ mode) shown in the graph of Fig. 11a.

[0229] FIG. 11b may be an output setting of the full-range speaker in a second operation mode of the display device 100, i.e., a second EQ mode. Referring to the graph of FIG. 11b, the output setting of the full-range speaker in the second operation mode is controlled by controlling the output in at least one frequency region compared to the output of the full-range speaker in the first operation mode on the graph of FIG. 11a. For example, in FIG. 11b, compared to FIG. 11a, the output in the first frequency region 1110 may be relatively decreased and the output in the second frequency region 1120 may be relatively increased. However, this is not limited to this. Meanwhile, the output of the full-range speaker of the display device 100 in FIG. 11b may be referred to as a second EQ mode (e.g., FIG. 9).

[0230] FIG. 11c may be an output setting of the full-range speaker in a third operation mode of the display device 100, i.e., a third EQ mode. Referring to the graph of FIG. 11c, the output setting of the full-range speaker in the third operation mode controls the output in at least one frequency range compared to the output of the full-range speaker in the first operation mode on the graph of FIG. 11a. For example, the output in the first frequency range 1130 may be relatively decreased, and the output in the second frequency range 1140 may be relatively increased. However, this is not limited to this. Meanwhile, the output of the full-range speaker of the display device 100 in FIG. 11b may be referred to as a third EQ mode (e.g., in FIG. 9).

[0231] Meanwhile, when comparing the graph of Figure 11c with the output of the full-range speaker in the second operating mode on the graph of Figure 11b, it can be seen that the first frequency ranges 1110 and 1130 are similar to each other, but the output is further reduced in the sub-range corresponding to relatively low frequencies in the first frequency range 1130 compared to Figure 11b. Also, the output of the second frequency ranges 1120 and 1140 is further reduced in the sub-range corresponding to relatively low frequencies in the frequency range 1140 compared to Figure 11b, but on the other hand, the output is further increased in the sub-range corresponding to high frequencies compared to Figure 11b.

[0232] Meanwhile, the audio output frequency band and audio level vary depending on the content, as shown in the graph of Figure 11. Therefore, the following embodiments may be referred to or combined.

[0233] According to an embodiment, the EQ mode control for each operation mode may be performed by dividing the audio frequency band of 20-20,000 Hz into a frequency range that most significantly affects the user's hearing when the same speaker output is affected by interference from the display 610 and a frequency range that does not, and controlling the divided ranges differently. For example, in the latter case, since the audio output control has a minimal effect on the user's hearing enhancement, the latter frequency range may be excluded from the frequency range to be controlled, and audio output may be controlled only for the former frequency range. In this case, various audio output control methods may be used, such as the methods described above. Meanwhile, the frequency range targeted for electronic audio output control, i.e., the frequency range that contributes to the user's hearing enhancement, may be divided into at least one or more sub-frequency ranges and individually controlled. In this case, the individual control may be performed based on personal information such as the user's age and gender, content attributes, etc.

[0234] According to an embodiment, control of the EQ mode corresponding to each operation mode can be performed by outputting an audio output corresponding to a first operation mode in the same manner in a changed operation mode, receiving a measured audio output (e.g., when measuring an audio level at a preset user position), and comparing the measured value of the audio output in the first operation mode with the measured value of the audio output in another operation mode. In this case, using a graph such as that shown in FIG. 11 as an example, frequency regions where an audio level difference equal to or greater than a preset critical value occurs are selected as candidate frequency regions, and at least one of the selected candidate frequency regions is determined as a final frequency region to be subject to audio control, and audio control can be performed on the frequency region. In this case, the determination method can determine only one or more frequency regions with the largest audio level difference as the frequency region to be controlled. Meanwhile, the audio level control criterion can be calculated and used as an average value of audio level differences of all candidate frequency regions where a difference equal to or greater than a critical value occurs, or by selecting and using any one of the average value of audio level differences excluding the largest and smallest audio level differences, the largest audio level difference, etc. Meanwhile, in relation to determining the control target, weights can be assigned depending on the frequency range among multiple candidate frequency ranges, or only frequency ranges that are considered to have a relatively small impact, for example, the aforementioned audible frequency range, can be selected to contribute to the user's hearing amplification effect, and the remaining ranges can be excluded.

[0235] According to the embodiment, ambient noise is detected taking into consideration the outdoor environment, and a weighting value is set according to the detected ambient noise (for example, a noise weighting value of 1 for a groove and a noise weighting value of 5 for outdoors), and the degree of the audio level control described above can be controlled differently depending on the set weighting value. In addition to the ambient noise, time of day, weather, location, etc. can also be taken into consideration to assign individual weighting values ​​and reflect them in the audio output control.

[0236] According to the embodiment, in the second or third operating mode, except for the first operating mode, audio output may be significantly different for each frame or scene, even if the content is the same. Therefore, the display apparatus 100 can not only uniformly apply audio output according to the operating mode, but also, if a change in audio output that exceeds a predetermined threshold is detected for each frame or scene compared to the previous frame or scene (e.g., as can be identified from the buffer), it can reflect this in the audio output control that is already being applied. Meanwhile, the above-described content can also be applied when the channel is changed even in the same operating mode, or when the content is changed even in the same channel.

[0237] In a similar manner, the above-mentioned content (field) may vary depending on the number of users detected in front of or around the display device 100, the distance from the users, the degree of user movement, position change, etc. For example, a preset weight may be assigned to the number of users, the distance from the users, etc., so that the audio output control can be taken into consideration.

[0238] As another example, the display apparatus 100 may set and apply a value for each operation mode based on the speaker output itself, rather than the user's position. In this case, the display apparatus 100 may control the output so that a preset speaker output value is applied according to the change in operation mode, and may also consider variables. In this case, the variables may include the above-mentioned conditions and weights.

[0239] Additionally, the display apparatus 100 may use an artificial intelligence engine including a trained artificial intelligence model, or may download or receive audio output control content that generally provides a user with listening inconvenience or satisfaction in each operation mode from a server (not shown) including the same, and reflect the content. Alternatively, the display apparatus 100 may learn from user feedback after controlling the audio output according to each operation mode, continuously update the artificial intelligence model, and control user-customized audio output according to each operation mode.

[0240] Next, the output of the tweeter speaker in Figure 12 will be described. As mentioned above, the output of the tweeter speaker basically corresponds to the high frequency band, and changing the operation mode may not make a significant difference. However, depending on the type and attributes of the content, the output control of the tweeter speaker according to the operation mode may be performed with reference to the control details of the full-range speaker described above.

[0241] Figure 12a also shows the output of the tweeter speaker in the first operation mode of the display device 100, but unlike the output of the full-range speaker in Figure 11, the output of the tweeter speaker in the second operation mode in Figure 12b and the output of the tweeter speaker in the third operation mode in Figure 12c are similar. Specifically, the output of the tweeter speaker in Figure 12b, i.e., the second operation mode, is slightly higher than the output in Figure 12a, i.e., the first operation mode, and the output in Figure 12c, i.e., the third operation mode, is slightly higher than the output in the second operation mode.

[0242] However, the speaker output of a tweeter, which is responsible for a relatively high frequency band, is less likely to be affected by a change in the operation mode than a full-range speaker because there is less need to adjust the speaker output in relation to the operation mode of the display apparatus 100. From this perspective, adjusting and controlling the speaker output in this specification can be interpreted as, for example, adjusting and controlling the output of a full-range speaker rather than the output of a tweeter speaker, but is not limited thereto.

[0243] 10, the frequency bands for the output of the full-range speaker may be divided into at least two or more, and in this case, the output change for each divided frequency band may be controlled to be different from each other. For example, if the divided frequency bands are a first frequency band for low sounds and a second frequency band for high sounds, the display device 100 may lower the output of the first frequency band and raise the output of the second frequency band.

[0244] Meanwhile, the display device 100 may acquire sensing information on ambient noise, etc., using the sensor unit 820, and set a weighting value for the acquired sensing information on ambient noise, etc., so that the weighting value is reflected when controlling speaker output according to each of the above-mentioned cases, i.e., the operating mode.

[0245] The display apparatus 100 may pre-map and store resolution control details of the display 610 in addition to the speaker output according to the operation mode. The display apparatus 100 may pre-map and store brightness control details of the display 610 in addition to the speaker output according to the operation mode. In this case, similar to the above-described speaker control method, a weight is assigned to the sensed value of the ambient illuminance, and the brightness, resolution, etc. of the display set according to the current operation mode can be additionally controlled according to the assigned weight.

[0246] 13 and 14 are diagrams illustrating usage scenarios according to operation modes of the display device 100 according to an embodiment of the present disclosure.

[0247] 13 shows an example of a usage scenario of the first operation mode of the display device 100. FIG. 14 shows an example of a usage scenario of the second and third operation modes of the display device 100.

[0248] 13(a) and 13(b), the first operation mode of the display device 100 may provide a single- or multi-user game application, a web browser application, etc. In addition, the display device 100 may be used as an audio-only device through the first operation mode.

[0249] Meanwhile, FIG. 14(a) illustrates the second operation mode of the display device 100, and FIG. 14(b) illustrates the third operation mode.

[0250] When viewing general videos, still images, or broadcast programs, they are provided in the second operating mode as shown in (a) of Figure 14. On the other hand, music applications that provide sheet music may be provided in the third operating mode as shown in (b) of Figure 14. Here, "provided" may mean that the operating mode is recommended to the user or that the operating mode is automatically switched to and provided without any separate user control.

[0251] Meanwhile, the display device 100 may automatically switch between the first to third operation modes in consideration of the attributes of content that the user wishes to play. For example, when a game application execution input is received from the user, the display device 100 may automatically switch to the first operation mode or provide a recommendation guide regarding the operation mode if it determines that there are relatively many touch inputs, etc., according to the received input (i.e., game application). As shown in (b) of Figure 14, when a music application execution request that outputs sheet music when playing guitar or piano on the entire screen of the display device 100 is received from the user, the display device 100 may automatically switch to the third operation mode or provide a recommendation guide.

[0252] 15 and 16 are diagrams illustrating control of the display device 100 according to an embodiment of the present disclosure.

[0253] The above-described operation modes of the display device 100 are based on the assumption that an object (ie, a user) is positioned in front of the display.

[0254] However, if a user who was positioned in front of the display device 100 moves to the side, as shown in FIG. 15, the user may no longer be positioned in front of the display device 100 and may not be able to fully view the content being output through the display 610.

[0255] In this case, the display apparatus 100 may detect the user's position and rotate at least one of the display 610 and the upper case 510 including the speaker according to the detected user's position, allowing the user to view content as if the user were positioned in front of the display apparatus 100. At this time, the attributes of the currently played content are also taken into consideration when rotating at least one of the display 610 and the upper case 510. For example, if video is more important content, only the display may be rotated; if audio is more important content, only the upper case 510 may be rotated or not; and if both video and audio are important, both may be rotated.

[0256] Meanwhile, the display device 100 may need to analyze the user's intention because unconditional rotation in response to the user's movement may not necessarily be in line with the user's intention. For this intention analysis, at least one of the following is referenced: the current time, the user's voice, content attributes, previously set schedules, and whether or not the user has made any additional input. For example, if the user has not transmitted a power-off command for the display device 100 but has not made any input after moving the device to the side, this can be interpreted as indicating that the user has not intended to use the display device 100 for at least a certain period of time. Therefore, if there has been no user input for a certain period of time, the display device 100 may be controlled to rotate so as not to provide content against the user's will. A server provided by the display device 100 manufacturer may be used in connection with the intention analysis.

[0257] In a similar manner, FIG. 16 may be for controlling the movement of the display device 100 when the height of the object, ie, the user, changes.

[0258] If a user is initially sitting and watching content using the display device 100 and then stands up, the angle formed between the user's eyes and the display 610 changes, which may cause disruption to the user's viewing.

[0259] 16, the display apparatus 100 can detect the user's eye height and adjust the angle between the display and the lower case 520 accordingly. In this case, the overlapping area of ​​the display with the speaker of the upper case 510 changes depending on the degree to which the angle between the display and the lower case 520 is adjusted. Therefore, the display apparatus 100 can determine whether to adjust the speaker output based on the difference in the overlapping area, and adjust the speaker output based on the determination result.

[0260] However, even in this case, as mentioned above, even if the user's height changes, it is difficult to interpret this as necessarily meaning that the user intends to continue watching. Similarly, only if there is additional input from the user can it be determined that the user intends to continue watching, and the angle of the display can be adjusted accordingly.

[0261] FIG. 17 is a diagram illustrating how separate operations of displays are controlled according to an embodiment of the present disclosure.

[0262] Referring to FIG. 17, the display may include a first display 1710 and a second display 1720.

[0263] In FIG. 17(a), a first display 1710 and a second display 1720 are in contact with each other and can function as if they were a single display as described above.

[0264] On the other hand, in (b) and (c) of FIG. 17, the first display 1710 and the second display 1720 are separated from each other and can operate as two displays.

[0265] In Fig. 17, even if the displays 1710 and 1720 function as a single display as shown in Fig. 17(a), they can be separated from each other, and a foldable stand may be assigned to each display to support its movement. The structure between each display and the foldable stand can be seen in the description of Fig. 7, and a duplicate description will be omitted here.

[0266] FIG. 17(b) shows a state in which the first display 1710 and the second display 1720 are separated and moved horizontally relative to each other.

[0267] Also, FIG. 17(c) shows a state in which the first display 1710 and the second display 1720 are separated and moved not only horizontally but also vertically.

[0268] (b) and (c) of Figure 17 may be such that one user can use different content (or channels) in a multi-view mode, or multiple users can use their desired content in a desired location via a desired display (1710 or 1720).

[0269] In the cases of (b) and (c) of Figure 17, the separation of the display results in relatively less interference and disturbance caused by the speaker output compared to (b) and (c) of Figure 6, so the speaker output change can be controlled so that it does not increase or decrease as much compared to Figures 10 and 11 described above.

[0270] FIG. 18 is a diagram illustrating the operation of the display device 100 including at least two displays.

[0271] For ease of explanation, FIG. 18 illustrates a display device 100 including physically separated and individual displays, i.e., two displays.

[0272] Each display 1810, 1820 can be individually controlled by a user. For convenience, each display 1810, 1820 may be provided with an individual mount, and an individual mechanism (e.g., a folding stand) may be connected to the lower case 520. According to an embodiment, one folding stand may be extended from the lower case 520, and only the second stand portion may be separated to support each display 1810, 1820.

[0273] In FIG. 18(a), each of the separated displays can be moved 90 degrees to the left and right from the lower case 520, allowing each user, ie, user A and user B, to view content individually.

[0274] On the other hand, in FIG. 18(b), each of the separated displays can be moved 45 degrees to the left and right from the lower case 520, allowing each user, ie, user A and user B, to view individual content.

[0275] In the cases of (a) and (b) in Figure 18, the displays are separated and can view the same or different content. In the former case, audio settings can be set collectively based on the relationship between each separated display and the upper case, but in the latter case, information about the content being provided through each display must be additionally referenced. In other words, in the latter case, if each user is viewing different content, the audio settings will differ depending on the type or attributes of the content provided through each display.

[0276] The type or attribute of content may represent the importance of audio in relation to audio. For example, in the case of a music playback program, the importance of audio may be considered relatively high, whereas in the case of content where video is more important, such as in gallery mode, the importance of audio may be considered relatively low. Therefore, if a music program is provided to user A through first display 1810 and a gallery or drama is provided to user B through second display 1820, audio related to the music program being provided through first display 1810 may be output or controlled to be output from the speaker provided in upper case 510, and the content being provided through second display 1820 may be replaced with subtitles.

[0277] FIG. 19 is a diagram illustrating an operation of a rollable display mounted on a display device 100 according to an embodiment of the present disclosure.

[0278] In FIG. 19, the display device 100 includes a rollable display inside a lower case 520, and the rollable display can be exposed to a predetermined height from the upper part of the lower case 520 depending on the display mode.

[0279] At this time, the operation mode of the display may be automatically determined based on at least one of the type of content, user settings, etc., or may be manually determined at the user's request.

[0280] For example, when only music is being played without short information such as weather or a music video, audio is relatively less important and can be provided in mode A.

[0281] If both video and audio are output and their importance is similar, they can be provided in mode B.

[0282] On the other hand, if both video and audio are output but video is more important, the video can be emphasized and provided in Mode C. In the case of Mode C, for example, the second operation mode of Fig. 6(b) or the third operation mode of Fig. 6(c) may be used.

[0283] If the display device 100 is operating in one display mode (e.g., mode C) according to the content type, etc., but the content type is changed at the user's request, etc., the display device 100 can automatically change the already set display mode from mode C to mode A or mode B according to the changed content type.

[0284] Meanwhile, in FIG. 19, for the sake of convenience, the display modes are divided into Mode A to Mode C. However, the extent to which the rollable display is exposed from the lower case 520, i.e., the height of the display, may be continuously changed or arbitrarily determined based on at least one of the content, the user, and the importance of the video and audio.

[0285] Unlike the previously described embodiments, FIGS. 20-25 disclose another embodiment for controlling the audio output of the upper case 510. FIG.

[0286] 20 to 22 are diagrams illustrating a display device 100 including a movable speaker structure according to an embodiment of the present disclosure.

[0287] First, in (a) of Figure 20, an embodiment is shown in which the upper case 510 of the display device 100 includes two speakers 2010 and 2020 that can be separated to the left and right, and in (b) of Figure 20, the upper case 510 of the display device 100 includes a speaker 2030 that can move up and down.

[0288] The cases of (a) and (b) in Figures 20 can also be used in the second operating mode (landscape mode) in Figure 6(b) or the third operating mode (portrait mode) in Figure 6(c).

[0289] Referring to (a) of FIG. 20, the first speaker 2010 and the second speaker 2020 can each be moved left and right in the horizontal direction. In this case, by moving the speakers 2010 and 2020 left and right, especially when the display operates in the third operating mode as shown in (c) of FIG. 6, the speakers can move left and right so as not to be obstructed by the display in front of them in the audio output direction, allowing the user to listen to the audio without any problems without controlling the audio output. Meanwhile, depending on the degree of left and right movement of the speakers, this can also be used in the second operating mode as shown in (b) of FIG. 6. Even if the speakers cannot be moved sufficiently to avoid audio output obstruction due to the display placed in front of them, the speaker output level can be controlled to a relatively low level compared to (b) of FIG. 6, thereby reducing obstruction to the user's audio listening.

[0290] On the other hand, in the case of Figure 20(b), where the speaker 2030 can move up and down vertically, if the speaker 2030 cannot move up and down when operating in the second operating mode as in Figure 6(b), its audio output would be interrupted by the display disposed in front of it as described above, and the audio would have to be controlled by changing the EQ mode as described above. However, if the speaker 2030 can move up and down as shown in Figure 20(b), audio output control may be relatively reduced or eliminated even when the display operates in the second operating mode as in Figure 6(b).

[0291] In addition, by combining the left-right movement of the speaker shown in (a) of Figure 20 (even in this case, the speaker may not necessarily be separated but may be able to move left-right) with the up-down movement of the speaker shown in (b) of Figure 20, the speaker can be moved to a position where the display minimizes interference with the speaker output, thereby minimizing audio output interference to the user.

[0292] Next, referring to FIG. 21, the first speaker 2110 can move by any angle in the direction of user 1, and the second speaker 2120 can move by any angle in the direction of user 2, and even if the front output direction of the audio is a front direction that corresponds 1:1 to the user as shown by the arrow, it can move a little further in relation to the display placed in front, different from what is shown.

[0293] In this case, unlike the one described above in FIG. 6, at least two full-range speakers are provided, and each speaker is provided in a user-customized format, thereby minimizing audio disturbance caused by the front-mounted display.

[0294] Unlike the above-described FIGS. 20 and 21, the upper case 510 including the speaker is physically separated or immovable, but in FIG. 22, only the speaker portion can move left and right or up and down.

[0295] FIG. 22(a) shows the original speaker position in the third operating mode shown in FIG. 6(c), and FIG. 22(b) shows the third operating mode in which the lower case remains the same, but only the speakers 2210 and 2220 move left and right, allowing the user to listen to the audio without having to control the audio output.

[0296] On the other hand, in Figures 23 and 24, instead of physically moving the upper speaker 510 or the speakers installed inside it left and right or up and down as in Figures 20 to 22 described above, the audio output direction is controlled to produce the same or similar effects.

[0297] 23 and 24 are diagrams illustrating a display device 100 having a speaker with controllable output direction according to an embodiment of the present disclosure.

[0298] First, in FIG. 23, the speakers themselves do not physically move horizontally or vertically, but each speaker 2310, 2320 is formed in an array structure, for example, as shown in FIG. 23(c) or (d), to be embodied so that it can have directionality, and the audio output direction at that position can be adjusted and controlled toward each user, for example, as shown in FIG. 23(a) to 23(b).

[0299] As shown in FIG. 23, when at least one speaker 2310, 2320 included in the lower case 520 is implemented in an array form, it is possible to adjust and control the audio output direction in the second operation mode as shown in FIG. 6(a) or the third operation mode as shown in FIG. 6(c) by processing it using DSP (Digital Signal Processing).

[0300] Meanwhile, as shown in Fig. 24, unlike the speakers 2310 and 2320 formed in an array structure in Fig. 23, a plurality of individual speakers may be arranged in a horizontal direction (2410, 2420) based on the upper case 510, the lower case 520, or the display. In this case, the types and attributes of the individual speakers provided in each case may be the same or different. For example, one of the individual speakers may be a full-range speaker and the other a tweeter speaker, etc. However, the present invention is not limited to this.

[0301] The display apparatus 100 can individually control whether each speaker is activated or not by selecting the degree of output during operation depending on whether the display apparatus 100 is in the second operation mode as shown in (a) of Fig. 24 or the third operation mode as shown in (b) of Fig. 24. For example, in the third operation mode as shown in (b) of Fig. 24, assuming that the output direction of the speakers is a straight forward direction, some of the individual speakers 2410 and 2420 that cause interference can be deactivated, and only the remaining individual speakers can be activated.

[0302] Meanwhile, at least one of the individual speakers included in each of the speakers 2410 and 2420 in FIG. 24 may be implemented in an array form.

[0303] FIG. 25 is a diagram illustrating the operation of the display apparatus 100 having a movable upper case with a speaker according to an embodiment of the present disclosure.

[0304] In the above-described embodiment, the display linked to the lower case 520 can be moved. Referring to FIG. 25 , which shows a side view of the display device 100, the upper case 510 including the speaker can also be moved to form any angle with the lower case 520. In this case, even if the speaker does not move by itself as in the above-described embodiment, the upper case 520 including the speaker can be moved to form any angle with respect to the audio output direction. Of course, the embodiment of FIG. 25 can also be combined with speaker movement and output direction control. A mechanism similar to the above-described mechanism may be used to control the movement of the speaker or upper case 520. Alternatively, the display device 100 may provide a user with a guide screen on the display for the recommended position or angle of the speaker or upper case 520.

[0305] FIG. 26 is a diagram illustrating how the display apparatus 100 controls audio output in cooperation with a peripheral audio device depending on the display operation mode according to an embodiment of the present disclosure.

[0306] As described above, the user can control the display device 100 by touching the display 610, but can also control the display device 100 by voice input via the artificial intelligence speaker 2610 or via the remote control device 200.

[0307] In this situation, when the display device 100 operates in any of the operation modes (a) to (c) of Figure 6, if it is linked to other audio devices in the vicinity, the above-mentioned audio output control will be different.

[0308] In this case, assuming that the peripheral audio devices 2620 and 2630 are, for example, auxiliary speakers such as woofers and are audio devices that have been registered in advance in the display device 100, the display device 100 can attempt to link or connect with each of the audio devices 2620 and 2630, for example, via Bluetooth.

[0309] The display apparatus 100 may first determine the operation mode, identify the user's position, and then control audio output through the speakers. In this case, if at least one auxiliary speaker 2620, 2630 is linked to output audio as shown in Fig. 26, output control for at least one speaker provided in the upper case 510 of the display apparatus 100 may be determined in consideration of various circumstances such as the type, performance, etc. of each auxiliary speaker 2620, 2630 and the relationship with the user's position.

[0310] In this case, the speaker provided in the upper case 510 of the display apparatus 100 may be turned off, and at least one of the external speakers 2620 and 2630 may be used to output audio for the content being output through the display 610. In this case, even if all the external speakers 2620 and 2630 are used, the audio control content for each external speaker may be different.

[0311] According to an embodiment of the present disclosure, when the upper case 510 of the display device 100 is opened, the display device 100 immediately enters the first operation mode, and in this case, content is output on the display without any additional special action by the user. That is, a fixing means provided on the outer surface of the lower case 520 can function as a kind of power trigger for the display device 100.

[0312] In this case, the display device 100 may act against the user's will, so if there is no additional input or control from the user within a predetermined time, it may determine that the viewing of the content has been accepted and output audio data for the content.

[0313] According to an embodiment, the display apparatus 100 may provide a list of previously viewed content from the time the upper case 510 is opened and immediately output selected content.

[0314] According to an embodiment, the display device 100 may provide recommended content or a list according to the time point based on the time point when the upper case 510 is opened. In this case, the time point may represent, for example, a time period (which may be defined as a season, a weekday, a weekend, morning, daytime, evening, etc.).

[0315] According to an embodiment, the display device 100 may provide recommended content or a list based on the weather at the time when the upper case 510 is opened. In this case, the weather may refer to the current and near future weather for a corresponding area based on location information such as GPS.

[0316] The recommended content may be determined by, for example, referring to currently hot content, viewer ratings, search term rankings on web browsers, etc. Alternatively, the recommended content may be determined by identifying a user or referring to registered user information, taking into consideration various information such as the user's schedule, SNS information, interest level, previous viewing history, etc.

[0317] Meanwhile, the above-described contents may be triggered not necessarily at the time when the upper case is opened, but by a specific input, gesture, voice, etc. after the upper case is opened.

[0318] Unless otherwise specified, the order of at least some of the operations disclosed in this disclosure may be performed simultaneously, may be performed in a different order than previously described, or may be omitted or added.

[0319] According to one embodiment of the present disclosure, the above-described method may be embodied as processor-readable code on a program-recorded medium, such as a ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc.

[0320] The display device described above is not limited to the configurations and methods of the above-described embodiments, and the above embodiments may be configured by selectively combining all or part of each embodiment to allow for various modifications. [Explanation of symbols]
