[0039] Throughout the accompanying drawings and detailed embodiments, unless otherwise described, it should be understood that the same reference numerals denote the same elements, features, and structures. For clarity, illustrative purposes, and convenience, the relative size, length, and thickness of layers, regions, and elements, and their depiction, may be exaggerated.

[0040] The advantages and features of this disclosure and its implementation methods will be illustrated by the following embodiments described with reference to the accompanying drawings. However, this disclosure may be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are examples and are provided so that this disclosure will be thorough and complete, assisting those skilled in the art in understanding the inventive concept, without limiting the scope of protection of this disclosure. Furthermore, this disclosure is limited only by the scope of the appended claims.

[0041] The shapes, dimensions (e.g., size, length, width, height, thickness, position, radius, diameter, and area), ratios, angles, numbers, number of elements, etc., disclosed herein (including those illustrated in the accompanying drawings) are merely examples, and therefore, this disclosure is not limited to the illustrated details. However, it should be noted that the relative dimensions of the parts illustrated in the accompanying drawings are part of this disclosure. The same reference numerals always refer to the same elements. In the following description, a detailed description of the relevant known art will be omitted where it is determined that such a detailed description would unnecessarily obscure the essential points of this disclosure. Where terms such as “comprise,” “have,” “include,” “contain,” “constitute,” “made of,” “formed of,” “composed of,” etc., are used in this disclosure, an additional part may be added unless “only,” “merely,” etc., are used. Singular terms may include plural forms unless otherwise noted. The word “exemplary” is used to mean used as an example or illustration. An implementation is an exemplary implementation. An aspect is an exemplary aspect. Terms such as “implementation method,” “example,” and “aspect” should not be construed as being preferred or advantageous over other implementation methods. Example implementation method, example, example implementation method, aspect, etc., can refer to one or more implementation methods, one or more examples, one or more example implementation methods, one or more aspects, etc., unless otherwise stated. Furthermore, the term “may” encompasses all the meanings of the term “can.”

[0042] In one or more respects, unless otherwise expressly stated, components, features, or corresponding information (e.g., grade, range, size, dimensions, etc.) are interpreted as including a range of errors or tolerances, even if no explicit description of such a range of errors or tolerances is provided. An error or tolerance range can be caused by a variety of factors (e.g., process factors, internal or external shocks, noise, etc.). When interpreting numerical values, values ​​are interpreted as including the range of errors, unless otherwise expressly stated.

[0043] When describing positional relationships, for example, when using terms such as “above,” “on top,” “top,” “above,” “below,” “under,” “near,” “adjacent,” “next to,” “beside,” “immediately next to,” “on one side or above,” etc., to describe the positional relationship between two parts (e.g., layers, membranes, regions, components, sections, etc.), one or more additional parts may be placed between the two parts unless more restrictive terms such as “immediately,” “closely,” “right,” or “exactly” are used. For example, when an element is described as being positioned “above,” “top,” “above,” “top,” “above,” “below,” “below,” “near,” “near,” “adjacent to,” “next to,” “beside,” “immediately next to,” or “on one side or above” of another element, the description should be interpreted to include cases where the elements are in direct contact with each other and cases where one or more additional elements are placed or inserted therebetween. In addition, terms such as "front", "back", "back", "left", "right", "top", "bottom", "down", "up", "above", "below", "up", "column", "row", "vertical", and "horizontal" can be used to refer to any reference system.

[0044] Spatial relative terms such as “below,” “under,” “down,” “above,” “above,” and “up” can be used to easily describe the relationship between one or more elements (e.g., layer, film, region, component, segment, etc.) and another one or more elements, as illustrated in the figure.

[0045] In addition to the directions illustrated in the figures, spatial relative terms can also be understood to include terms that describe different orientations of the device during use or operation. For example, when the device in the figure is flipped, an element described as "below" or "under" other elements can be placed "above" other elements. Therefore, the exemplary terms "below" or "under" can include both downward and upward directions.

[0046] It will be understood that while terms such as “first,” “second,” etc., may be used herein to describe various elements (e.g., layers, films, regions, components, segments, etc.), these elements should not be limited by such terms to any particular order, priority, or number of elements. These terms are merely used to distinguish one element from another and may not specify any order. For example, a first element may be referred to as a second element without departing from the scope of this disclosure, and similarly, a second element may be referred to as a first element. Furthermore, without departing from the scope of this disclosure, first elements, second elements, etc., may be arbitrarily named as appropriate by those skilled in the art. For clarity, the function or structure of these elements (e.g., first element, second element, etc.) is not limited by the ordinal number or name preceding the element. Additionally, a first element may include one or more first elements. Similarly, a second element, etc., may include one or more second elements, etc.

[0047] In describing the elements of this disclosure, terms such as “first,” “second,” “A,” “B,” “(a),” “(b),” etc., may be used. These terms are intended to identify corresponding elements from other elements, and the basis, order, or number of corresponding elements shall not be limited by these terms. Describing an element (e.g., layer, film, component, unit, wire, electrode, material, structure, etc.) as “connected,” “joined,” “attached,” or “adhered” to another element means that the element may be directly connected, joined, attached, or adhered to the other element, or indirectly connected, joined, attached, or adhered to the other element, with one or more intermediate elements “set” or “interposed” between these elements, unless otherwise specified.

[0048] The term “at least one” should be understood to include any and all combinations of one or more of the items listed. For example, “at least one of the first, second and third items” means any combination of all items proposed using two or more of the first, second and third items, as well as the first, second or third item alone.

[0049] In this disclosure, "display device" can include display devices in the narrow sense, such as display modules (or display components) including a display panel and a driver for driving the display panel, light-emitting display modules (e.g., organic light-emitting display modules, quantum dot light-emitting display modules), or liquid crystal display modules (LCMs). Furthermore, a display module can include fixed devices (or fixed equipment) or fixed electronic devices (such as notebook computers, televisions, computer monitors, assembly equipment including equipment for vehicles, automotive equipment, or other types of equipment for vehicles) or mobile electronic devices (such as smartphones, tablets, etc.), both of which constitute a complete product (or final product) including display modules such as liquid crystal display modules and light-emitting display modules (e.g., quantum dot light-emitting display modules, organic light-emitting display modules).

[0050] Therefore, the display device according to the exemplary embodiments of this disclosure may include the display device itself, such as a liquid crystal display module, an organic light-emitting display module, a quantum dot light-emitting display module, a micro light-emitting diode display module, etc., as well as a fixed device that includes a liquid crystal display module, an organic light-emitting display module, a quantum dot light-emitting display panel, a micro light-emitting diode display module, etc., as a final consumer device or application product.

[0051] The display device according to the exemplary embodiments of this disclosure can be implemented as a user interface device such as a central control panel in a car, and therefore can be applied to vehicles. For example, the display device can be positioned between passengers sitting in two front seats so that vibrations of the display panel are transmitted into the vehicle interior. Therefore, the audio experience inside the vehicle is improved compared to the case where speakers are positioned on the interior side of the vehicle.

[0052] Features of the various embodiments of this disclosure may be linked or combined with each other in part or in whole, and may interact with each other in various ways and be technically driven, as will be fully understood by those skilled in the art. Embodiments of this disclosure may be practiced independently of each other or may be practiced together in an interdependent manner.

[0053] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0136] According to an exemplary embodiment of this disclosure, the host control unit 191 of the display device 100 can receive an identification signal (or authentication signal) sent from the sound device 300 via a general-purpose input / output port 185, and can perform a connection (or pairing) operation between the display device 100 and the sound device 300 based on the received identification signal (or authentication signal). For example, since the identification information of the sound device 300 is stored in the storage unit 196, the host control unit 191 can identify the received identification signal and the identification signal stored in the storage unit 196 to complete the connection (or pairing) operation between the display device 100 and the sound device 300.

[0137] According to an exemplary embodiment of this disclosure, the host control unit 191 can set the sound mode of the display device 100 based on whether the sound device 300 is connected (or paired) to the display device 100 via a general-purpose input / output port 185 or via a wireless communication unit. That is, the sound mode can be set among multiple different sound modes based on the connection type (e.g., wired or wireless) used to connect the display device 100 and the sound device 300. For example, the external sound device 300 and the sound output device in the display device 100 can be configured to selectively output sound according to the sound mode. For example, the sound mode can include multiple different sound modes such as a first sound mode to a third sound mode. For example, the sound output device 150 at the display device 100 can be configured to output sound according to the first sound mode or the third sound mode. The sound output device 150 and the vibration device at the display device 100 can be configured to output sound according to the first sound mode or the third sound mode. The external sound device 300 can be configured to output sound according to the first sound mode or the second sound mode. Alternatively, the sound output device 150 and vibration device 170 at the display device 100 can be configured to output sound according to a second sound mode. The external sound device 300 can be configured to output sound according to a third sound mode.

[0138] According to an exemplary embodiment of this disclosure, when the host control unit 191 is connected (or paired) with the sound device 300 via the general-purpose input / output port 185 and the signal cable 200, the host control unit 191 can set the display device 100 to a first sound mode. That is, the first sound mode is set in response to the display device 100 and the sound device 300 being connected to each other via the signal cable 200 (e.g., wiring). For example, when the sound device 300 and the display device 100 are connected via the signal cable 200, the sound device 300 and the display device 100 can automatically connect (or pair). For example, the host control unit 191 can control the output of sound through each of the display device 100 and the sound device 300 according to the first sound mode. The host control unit 191 or the sound processing unit 193 can generate surround sound data corresponding to the number of surround sound channels according to the first sound mode. For example, the host control unit 191 can output sound from at least one of the vibration device 170 and the sound output device 150 of the display device 100 according to the surround sound data of the first sound mode. As another example, the host control unit 191 can output sound from at least one of the sound output device 150 and the vibration device 170 of the display device 100 according to the stereo sound data of the first sound mode. Simultaneously, the host control unit 191 can control the sound device 300 to output sound. For example, the first sound mode can be a surround sound mode, a 5.1 channel mode, or a stereo mode. Therefore, during the first sound mode, the sound device 300 and the internal sound output devices of the display device 100 (e.g., at least one of the sound output device 150 and the vibration device 170) output sound.

[0139] According to the first sound mode of the example implementation, such as Figure 5A As shown, the display device 100 according to an exemplary embodiment of this disclosure can output a left low-frequency (LLS) sound based on surround sound data according to a first sound mode, and output a right low-frequency (RLS) sound based on the driving of one or more first sound output devices 151 of the sound output device 150. Additionally, the sound device 300 can output a left high-frequency (LHS) sound based on surround sound data according to the first sound mode, and output a right high-frequency (RHS) sound based on the driving of one or more first speakers 331, and output a right high-frequency (RHS) sound based on the driving of one or more second speakers 332. Therefore, the display device 100 (or display system) including the sound device 300 can output four or more channels of surround sound (or stereo sound) according to the first sound mode via the left low-frequency (LLS), right low-frequency (RLS), left high-frequency (LHS), and right high-frequency (RHS).

[0140] Furthermore, the display device 100 according to the exemplary embodiment of this disclosure can, according to a first sound mode, output left center sound (LMS) based on the vibration of the display member 110 caused by the vibration (or drive) of one or more first vibration devices 171 of the vibration device 170, and can, according to the first sound mode, output right center sound (RMS) based on the vibration of the display member 110 caused by the vibration (or drive) of one or more second vibration devices 172 of the vibration device 170. Accordingly, the display device 100 (or display system) including the sound device 300 can, according to the first sound mode, output six or more channels of surround sound (or stereo sound) through left low sound (LLS), right low sound (RLS), left center sound (LMS), right center sound (RMS), left high sound (LHS), and right high sound (RHS).

[0141] According to an exemplary embodiment of this disclosure, when the host control unit 191 is not connected (or paired) with the sound device 300 via the general-purpose input / output port 185 and the signal cable 200, but is connected (or paired) with the sound device 300 via the wireless communication unit 195, the display device 100 can be set to a second sound mode. That is, the second sound mode is set in response to the display device 100 and the sound device 300 being wirelessly connected to each other. The host control unit 191 or the sound processing unit 193 can generate first stereo data corresponding to the number of stereo channels according to the second sound mode. For example, the host control unit 191 can control the sound output of the display device 100 to be deactivated, and can control the output of sound through the sound device 300 according to the second sound mode. For example, the host control unit 191 can deactivate the drive of each of the sound output device 150 and the vibration device 170 of the display device 100 according to the second sound mode. Simultaneously, the host control unit 191 can control the sound device 300 to output sound according to the first stereo data in the second sound mode. For example, the second sound mode can be the first stereo mode, the external stereo mode, or the external speaker sound mode. Therefore, during the second sound mode, the sound device 300 outputs sound, but the internal sound output device of the display device 100 (e.g., at least one of the sound output device 150 and the vibration device 170) does not output sound.

[0142] According to the second sound mode of the display device 100 according to an exemplary embodiment of the present disclosure, such as Figure 5BAs shown, the display device 100 can activate the driving of one or more first audio output devices 151 of the audio output device 150 according to the second sound mode, and the audio device 300 can output left high-frequency (LHS) sound based on the first stereo data through the driving of one or more first speakers 331 according to the second sound mode of the display device 100, and can output right high-frequency (RHS) sound based on the first stereo data through the driving of one or more second speakers 332 according to the second sound mode of the display device 100. Accordingly, the display device 100 (or display system) including the audio device 300 can output two or more channels of stereo (or first stereo) sound through the left high-frequency (LHS) and right high-frequency (RHS) sound according to the second sound mode.

[0143] According to an exemplary embodiment of this disclosure, when the host control unit 191 is not connected (or paired) with the sound device 300 via any of the general purpose input / output port 185, signal cable 200, and wireless communication unit 195, the host control unit 191 can set the display device 100 to a third sound mode. That is, the third sound mode is set in response to the display device 100 and the sound device 300 not being connected to each other. The host control unit 191 or the sound processing unit 193 can generate second stereo data corresponding to the number of stereo channels according to the third sound mode. For example, the host control unit 191 can control the sound output of the sound device 300 to be deactivated according to the third sound mode, and sound can be output through the display device 100. For example, the host control unit 191 can deactivate the drive of the sound device 300 according to the third sound mode, and control the output of sound from at least one of the sound output device 150 and the vibration device 170 of the display device 100. For example, the third sound mode can be a normal mode, a second stereo mode, an internal stereo mode, or an internal speaker sound mode. Therefore, during the third sound mode, the sound device 300 does not output sound, and the internal sound output device of the display device 100 (e.g., at least one of the sound output device 150 and the vibration device 170) outputs sound.

[0144] According to the third sound mode of the display device 100 according to the exemplary embodiment of this disclosure, such as Figure 5CAs shown, the display device 100 can activate the driver of the sound device 300 according to the third sound mode, and can output left bass LLS through the driving of one or more first sound output devices 151 of the sound output device 150 based on the second stereo data, and can output right bass RLS through the driving of one or more second sound output devices 152 of the sound output device 150 based on the second stereo data. Accordingly, the display device 100 (or display system) including the sound device 300 can output two or more channels of stereo (or second stereo) through the left bass LLS and right bass RLS according to the third sound mode.

[0145] Furthermore, the display device 100 according to embodiments of this disclosure can, based on second stereo data and a third sound mode, output left center sound (LMS) based on the vibration of the display member 110 caused by the vibration (or drive) of one or more first vibration devices 171 of the vibration device 170, and can, based on second stereo data and a third sound mode, output right center sound (RMS) based on the vibration of the display member 110 caused by the vibration (or drive) of one or more second vibration devices 172 of the vibration device 170. Accordingly, the display device 100 (or display system) including the sound device 300 can, based on the third sound mode, output four or more channels of surround sound (or stereo effect sound) through left low sound (LLS), right low sound (RLS), left center sound (LMS), right center sound (RMS), left high sound (LHS), and right high sound (RHS).

[0146] According to an example embodiment of this disclosure, the host control unit 191 can read the sound output characteristic information of the connected (or paired) sound device 300 from the storage unit 196 when the display device 100 and the sound device 300 are connected (or paired) to each other, and can provide the sound output characteristic information to the sound processing unit 193.

[0147] According to an exemplary embodiment of this disclosure, when the display device 100 and the sound device 300 are connected (or paired) to each other, the host control unit 191 receives connection sound characteristic information sent from the microphone device 350 of the sound device 300 via the wireless communication unit 195 or the general input / output port 185, and generates sound correction information for correcting the sound output characteristics of the sound device 300 by analyzing and comparing the received connection sound characteristic information with reference connection sound characteristic information stored in the storage unit 196, and then provides the generated sound correction information to the sound processing unit 193.

[0148] The sound processing unit 193 can correct and output the frequency characteristics and noise characteristics of the sound data based on the sound correction information provided from the host control unit 191, but the embodiments of this disclosure are not limited thereto. For example, sound data correction based on sound correction information can be performed by the host control unit 191.

[0149] According to an exemplary embodiment of this disclosure, the host control unit 191 can be configured to receive audio information transmitted from the audio device 300 via the wireless communication unit 195 or the general purpose input / output port 185, and to perform control operations corresponding to the received audio information. For example, the host control unit 191 can be configured to delay the audio data transmitted to the audio device 300, or to correct the frequency characteristics of the audio data based on the received audio information.

[0150] According to an exemplary embodiment of this disclosure, the sound processing unit 193 or the host control unit 191 compares the sound correction information sent from the microphone device 350 of the sound device 300 with the reference connection sound characteristic information, such as... Figure 6A The delay time Td between the sound correction information SI and the reference connection sound characteristic information RI is calculated as shown, and the sound data is delayed by the calculated delay time Td.

[0151] According to another exemplary embodiment of this disclosure, the sound processing unit 193 or the host control unit 191 can compare the sound correction information sent from the microphone device 350 of the sound device 300 with the reference connection sound characteristic information, and can perform operations as follows: Figure 6B The frequency deviation between the sound correction information SI and the reference connection sound characteristic information RI is calculated based on the reference connection sound characteristic information RI, and the sound data can be corrected by reflecting the calculated frequency deviation in the sound data.

[0152] According to an example embodiment of the present disclosure, the host control unit 191 can receive ambient sound information transmitted from the microphone device 350 of the sound device 300 via the wireless communication unit 195 or the general-purpose input / output port 185. It can compare the received ambient sound information with the optimal sound characteristic information stored in the storage unit 196, generate sound optimization information for optimizing the sound output characteristics of the sound device 300, and provide the generated sound optimization information to the sound processing unit 193.

[0153] According to an exemplary embodiment of this disclosure, the sound processing unit 193 or the host control unit 191 can correct the sound data to have frequency characteristics corresponding to sound optimization information generated based on ambient sound information transmitted from the microphone device 350 of the sound device 300. For example, the sound processing unit 193 or the host control unit 191 can, as... Figure 6AThe sound data can be corrected by calculating the delay time between the surrounding sound information and the sound data, as shown, or by means of... Figure 6B The frequency response deviation between ambient sound information and sound data is calculated to correct the sound data.

[0154] According to an exemplary embodiment of this disclosure, the host control unit 191 can receive audio information, including voice recognition information transmitted from the microphone device 350 of the audio device 300, via the wireless communication unit 195 or the general-purpose input / output port 185, and can control the operation of one or more of the display device 100 and the audio device 300 in response to the received voice recognition information. For example, the host control unit 191 can perform control operations such as volume adjustment, powering off the display device, or powering on the display device based on the user's voice recognition information.

[0155] As described above, the display device 100 and the sound device 300 according to the exemplary embodiments of this disclosure can be connected or paired with each other by wired and wireless methods, thereby shortening the connection time and pairing time between the display device 100 and the sound device 300, and minimizing the loss of sound data generated during the connection time and pairing time between the display device 100 and the sound device 300.

[0156] Furthermore, the display device 100 according to an exemplary embodiment of this disclosure can selectively output sound via one or more of an internal sound output device 150, a vibration device 170, and an external sound device 300 based on any one of a first to a third sound mode corresponding to a connection (or pairing) with the sound device 300 via a signal cable 200 and a general-purpose input / output port 185 and a connection (or pairing) with the sound device 300 via a wireless communication unit 195. Accordingly, the display device 100 according to an exemplary embodiment of this disclosure can provide not only stereo sound to the user but also surround sound or stereo effect sound.

[0157] Furthermore, the display device 100 according to the example embodiments of this disclosure can correct the sound quality of the sound, or can perform control operations based on sound information received by a microphone device 350 embedded (or built into) an external sound device 300.

[0158] According to an exemplary embodiment of the present disclosure, the sound device 300 can output sound or stereo corresponding to sound data sent from the display device 100 to the sound output device 150 of the display device 100, or can output sound together with the display device 100 to provide stereo sound or surround sound to the user or viewer.

[0159] According to an exemplary embodiment of the present disclosure, the sound device 300 can perform real-time correction and real-time optimization of the sound data generated by the display device 100 by providing sound information received through the microphone device 350 to the display device 100, can perform control operations corresponding to user voice, and can execute the Voice Internet Protocol.

[0160] According to an exemplary embodiment of this disclosure, the sound device 300 can perform voice Internet Protocol or closed-circuit television functions through the camera device 360, thereby transmitting captured image information of the surrounding environment to the display device 100 or the user's terminal device in real time.

[0161] Figure 7 This is a flowchart illustrating a method for driving a display device according to an exemplary embodiment of the present disclosure. Figure 7 A method for driving a display device paired with a sound device according to an exemplary embodiment of the present disclosure is illustrated.

[0162] Reference Figure 2 and Figure 7 A method for driving a display device paired with a sound device, according to an example embodiment of this disclosure, is described. The method for driving the display device includes... Figures 1 to 6B Repeating parts that are identical to each other will be omitted or briefly described.

[0163] First, based on the operation of the user or viewer, the display device 100 is turned on (powered on) (S100).

[0164] Then, it is determined whether the display device 100 is connected (or paired) with the sound device 300 (S110). For example, in step S110, it can be determined whether the display device 100 is connected (or paired) with the sound device 300 through the general purpose input / output port 185 and the signal cable 200.

[0165] Next, based on the determination result of S110, if the display device 100 is connected (or paired) with the sound device 300 by using wiring ("Yes" in S110), the display device 100 switches to the first sound mode and outputs surround sound through the display device 100 and the sound device 300, thereby providing surround sound to the user or viewer (S120).

[0166] According to an exemplary embodiment of this disclosure, step S120 may include the following steps: converting the display device 100 into a first sound mode (S121), converting sound data into surround sound data according to the first sound mode and sending the surround sound data to the sound device 300 (S122), and outputting sound through one or more of the sound output device 150 and the vibration device 170 of the display device 100 according to the surround sound data, while simultaneously outputting sound through the sound device 300 (S123).

[0167] In step S122, the surround sound data can be transmitted to the sound device 300 via signal cable 200 or wireless communication.

[0168] In step S123, as Figure 5A As shown, the surround sound according to the first sound mode may include left low-frequency (LLS) and right low-frequency (RLS) output from one or more first sound output devices 151 and one or more second sound output devices 152 of the sound output devices 150 of the display device 100, and left high-frequency (LHS) and right high-frequency (RHS) output from one or more first speakers 331 and one or more second speakers 332 of the sound device 300, thereby enabling the display device 100 (or display system) including the sound device 300 to output four or more channels of surround sound (or stereo sound) according to the first sound mode. Additionally, in step S123, the surround sound according to the first sound mode may also include, for example... Figure 5A The left center sound LMS and right center sound RMS are shown as output by the vibration of the display member 110, which is vibrated (or driven) by each of one or more first vibration devices 171 and one or more second vibration devices 172 included in the vibration device 170 of the display device 100, respectively. Thus, the display device 100 (or display system) including the sound device 300 can output six or more channels of surround sound (or stereo sound) according to the first sound mode.

[0169] Then, based on the determination result of S110, if the display device 100 is not connected (or paired) with the sound device 300 by using wiring ("No" in S110), it is determined whether the display device 100 is wirelessly connected (or paired) with the sound device 300. For example, in step S210, it is determined that the display device 100 is wirelessly connected (or paired) with the sound device 300 via wireless communication.

[0170] Next, based on the determination result of S210, if the display device 100 is wirelessly connected (or paired) with the sound device 300 ("Yes" in S210), the display device 100 switches to the second sound mode and outputs the first stereo sound only through the sound device 300, thereby providing stereo sound to the user or viewer (S220).

[0171] According to an exemplary embodiment of this disclosure, step S220 may include the following steps: switching the display device 100 to a second sound mode (S221), converting sound data into first stereo data according to the second sound mode and sending the first stereo data to the sound device 300 (S222), deactivating the sound output of the vibration device 170 and the sound output device 150 in the display device 100, and simultaneously outputting first stereo through the sound device 300 according to the first stereo data (S223).

[0172] In step S222, the first stereo data can be transmitted to the sound device 300 via signal cable 200 or wireless communication.

[0173] In step S223, as Figure 5B As shown, the first stereo according to the second sound mode may include left high-frequency (LHS) and right high-frequency (RHS) output from one or more first speakers 331 and one or more second speakers 332 of the sound device 300, thereby the display device 100 (or display system) including the sound device 300 can output two or more channels of stereo according to the second sound mode.

[0174] Then, based on the determination result of S210, if the display device 100 is not wirelessly connected (or paired) with the sound device 300 ("No" in S210), the display device 100 switches to the third sound mode and outputs the second stereo sound only through the display device 100, thereby providing stereo sound to the user or viewer (S320).

[0175] According to an example embodiment of the present disclosure, step S320 may include the following steps: switching the display device 100 to a third sound mode (S321), converting sound data into second stereo data according to the third sound mode and outputting the second stereo data to the sound output device 150 in the display device 100 (S322), deactivating the sound output of the sound device 300, and simultaneously outputting second stereo data through the sound output device 150 (S323).

[0176] In step S323, the second stereo according to the third sound mode may include left bass LLS and right bass RLS output from one or more first sound output devices 151 and one or more second sound output devices 152 of the sound output devices 150 of the display device 100, respectively, such as Figure 5C As shown.

[0177] According to another exemplary embodiment of this disclosure, in step S322, the second stereo data may be additionally output to the vibration device 170 of the display device 100. In this case, in step S323, the second stereo data may be output through each of the sound output device 150 and the vibration device 170 of the display device 100. For example, as Figure 5C As shown, the second stereo according to the third sound mode may include left low sound LLS and right low sound RLS output from one or more first sound output devices 151 and one or more second sound output devices 152 of the sound output devices 150 of the display device 100, and left center sound LMS and right center sound RMS output by vibration of the display member 110 according to the vibration of each of one or more first vibration devices 171 and one or more second vibration devices 172 of the vibration devices 170.

[0178] According to another exemplary embodiment of this disclosure, in step S322, the sound data according to the third sound mode can be converted into surround sound data and can be output to each of the sound output device 150 and the vibration device 170 in the display device 100. Therefore, in step S323, surround sound can be output instead of second stereo sound. For example, as Figure 5C As shown, the surround sound according to the third sound mode may include left bass LLS and right bass RLS output from one or more first sound output devices 151 and one or more second sound output devices 152 of the sound output devices 150 of the display device 100, and left center LMS and right center RMS output according to the vibration of the display member 110 caused by the vibration (or drive) of one or more first vibration devices 171 and one or more second vibration devices 172 of the vibration devices 170. Therefore, the display device 100 (or display system) including the sound device 300 can output four or more channels of surround sound (or stereo sound) according to the third sound mode.

[0179] Accordingly, the method for driving the display device 100 according to the example embodiments of this disclosure can provide not only stereo sound but also surround sound or stereo effect sound to the user through one or more of the internal sound output device 150, the vibration device 170 and the external sound device 300, based on any one of the first to third sound modes corresponding to one or more of the wired and wireless connections between the display device 100 and the sound device 300.
