In the following description, when it is determined that a detailed description of a related known function or configuration would unnecessarily obscure the key points of the present disclosure, the detailed description will be omitted.

[0142] In the case where “including,” “having,” and “comprising” described in the present specification are used, another component may be added unless “only” is used. Terms in the singular form may include plural forms unless otherwise described.

[0143] When interpreting an element, although there is no explicit description of the error or tolerance range, the element is interpreted as including the error or tolerance range.

[0144] When describing a positional relationship, for example, when the positional relationship between two components is described as, for example, "on," "above," "below," and "after," one or more other components may be disposed between the two components, unless more restrictive terms, such as "directly" or "directly," are used.

[0145] When describing a temporal relationship, for example, when a time sequence is described as, for example, "after," "subsequently," "next," and "before," discontinuities may be included unless more restrictive terms such as "just," "immediately," or "directly" are used.

[0146] It should be understood that although the terms "first", "second", etc. may be used to describe various elements in this article, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, without departing from the scope of the present disclosure, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

[0147] When describing the elements of the present disclosure, the terms "first", "second", "A", "B", "(a)", "(b)", etc. may be used. These terms are intended to distinguish corresponding elements from other elements, and the basis, order or number of corresponding elements should not be limited by these terms.

The middle frame 700 according to some embodiments of the present disclosure may be coupled or connected to each other so that the support portion 710 and the side wall portion 730 form a single body, thereby having a frame structure having a “┠”-shaped cross section.

[0214] The display apparatus according to one embodiment of the present disclosure may include an adhesive member instead of the middle frame 700 .

[0215] The adhesive member may be located between the rear edge of the display device 100 and the front edge of the support member 300, and may provide a gap space GS between the display device 100 and the support member 300.

The second sidewall may be located between the outer surface of the display device 100 and the first sidewall. For example, the second sidewall may not be exposed to the outermost surface of the display device and may be covered by the first sidewall, thereby improving the side appearance design of the display device.

[0218] Therefore, a display device according to one embodiment of the present disclosure can output sound PVS in a forward direction FD based on the vibration of the display device 100 (e.g., the display panel 110) caused by the vibration of one or more vibration devices 500 disposed between the display device 100 and the supporting member 300, thereby enhancing the immersive experience of a viewer viewing an image displayed by the display device.

[0219] Furthermore, in the display apparatus according to one embodiment of the present disclosure, since the sound PVS is generated based on the vibration of the display device 100 (eg, the display panel 110 ), a separate speaker may not be provided, thereby enhancing the degree of freedom in design of the complete apparatus and arrangement of elements.

[0220] FIG. 3A to FIG. 3C A vibration device according to one embodiment of the present disclosure is shown.

[0221] Reference FIG. 3A to FIG. 3C, one or more vibration devices 500 may include a bobbin 1650 disposed around a magnet 1620 and a coil 1660 disposed around the bobbin 1650 .

[0222] For example, the magnet 1620 may be disposed on the first plate 1610. The magnet 1620 may use a sintered magnet of barium ferrite, and the magnet 1620 may be made of iron (III) oxide (Fe 2 O 3 ), barium carbonate (BaCO 3 ; "barium carbonate"), neodymium (Nd) magnets, strontium ferrite (Fe 12 O 19 Sr), alloy casting magnets including aluminum (Al), nickel (Ni) and cobalt (Co), and / or the like. As another embodiment, the neodymium magnet may be neodymium iron boron (Nd-Fe-B). However, the embodiments of the present disclosure are not limited to these materials or examples.

[0223] The central magnetic pole 1630 may be disposed on the magnet 1620 . The central magnetic pole 1630 may be referred to as a pole piece. As another embodiment of the present disclosure, a pole piece may also be disposed on the central magnetic pole 1630 .

[0224] The bobbin 1650 may surround the magnet 1620. For example, the bobbin 1650 may be disposed on the first plate 1610. The bobbin 1650 may have a circular shape or an oval shape, but the embodiments of the present disclosure are not limited thereto. The oval shape may have an elliptical shape, a rectangular shape with rounded corners, or a non-circular curved shape whose width is different from its height, but the present embodiment is not limited thereto. For example, in the bobbin 1650 having an oval shape, the ratio of the major axis diameter to the minor axis diameter may be configured to be 1.3:1 to 2:1. The bobbin 1650 having an oval shape may improve the sound of the high-pitched vocal cords better than a circular shape, and may reduce the generation of heat caused by vibration, thereby having excellent heat dissipation characteristics.

[0225] The coil 1660 according to some embodiments of the present disclosure may be wound around the outer circumferential surface of the bobbin 1650, and a sound generating current (or voice current) may be provided thereto from the outside. The coil 1660 may be lowered or raised together with the bobbin 1650. The coil 1660 may be referred to as a voice coil. When current is applied to the coil 1660, based on the applied magnetic field generated around the coil 1660 and the external magnetic field generated around the magnet 1620, the entire portion of the bobbin 1650 may move up and down according to Fleming's left-hand rule, and may generate sound PVS or sound waves based on the vibration of the display device 100 caused by the vertical movement (or vibration) of the bobbin 1650.

[0226] The bobbin 1650 according to some embodiments of the present disclosure may be disposed on the first plate 1610 to surround the magnet 1620. According to one embodiment of the present disclosure, when the coil 1660 is wound around the outer peripheral surface of the bobbin 1650, heat generated in the coil 1660 may be transferred to the bobbin 1650, and the coil 1660 may include a material with good heat dissipation characteristics, so as to reduce image quality defects affecting the display panel 110 due to the heat of the bobbin 1650.

[0227] Because the bobbin 1650 according to some embodiments of the present disclosure vibrates upward and downward, eccentric vibration (or horizontal vibration) may occur due to vertical vibration, and the eccentric vibration of the bobbin 1650 may be affected by the weight of the bobbin 1650. The weight of the bobbin 1650 may be affected by the weight of the coil 1660. Therefore, when the weight of the coil 1660 is reduced, the eccentric vibration of the bobbin 1650 can be reduced. Therefore, considering the heat transferred to the bobbin 1650 and the eccentric vibration of the bobbin 1650, the coil 1660 may have better heat dissipation characteristics because its thermal conductivity is better than copper, which is a material of a general coil, and may include an aluminum (Al) material having better heat dissipation characteristics and being lighter than copper.

[0228] In addition, in aluminum, since oxides are formed in the air, it may not be easy to perform welding when manufacturing the vibration device 500, so the coil 1660 according to one embodiment of the present disclosure may include an aluminum (Al) layer (or a first metal layer) for heat dissipation and a metal covering layer (or a second metal layer) surrounding the Al layer. The metal covering layer may include one of copper (Cu), silver (Ag), and gold (Au). For example, the coil 1660 may be a copper-clad aluminum wire covered with copper. The metal covering layer may be formed as a thin film type outside the first metal layer, so the increase in the weight of the coil 1660 may not be greatly affected. Therefore, compared with a coil including only Cu or Cu wire, the weight of the coil 1660 according to one embodiment of the present disclosure can be reduced by about 60%.

[0229] According to some embodiments of the present disclosure, the bobbin 1650 may include a structure including a material obtained by processing pulp or paper, aluminum (Al) or magnesium (Mg) or an alloy thereof, or a synthetic resin such as polyimide. For example, the bobbin 1650 may be implemented using a polyimide film having relatively good heat dissipation characteristics and relatively light weight to prevent image quality defects of the display panel 110 caused by heat generated in the coil 1660.

[0230] The polyimide film may have physical properties that remain unchanged over a wide temperature range of -273°C to 400°C, and may have heat resistance, electrical insulation, flexibility, and non-flammability. In addition, since the polyimide film has good thermal and mechanical strength, the polyimide film may enhance the reliability of the bobbin 1650, and may reduce the generation of heat caused by the vibration of the bobbin 1650 based on excellent heat dissipation characteristics. For example, the polyimide film may be KAPTON, and may be a condensate of pyromellitic dianhydride and 4,4'-diaminodiphenyl ether, but embodiments of the present disclosure are not limited thereto.

[0231] The central magnetic pole 1630 may be accommodated or inserted into the bobbin 1650, and may guide the rise or fall of the bobbin 1650. For example, since the central magnetic pole 1630 is accommodated or inserted into the bobbin 1650, the outer peripheral surface of the central magnetic pole 1630 may be surrounded by the bobbin 1650. The central magnetic pole 1630 may be referred to as a lifting guide or a pole piece, but the embodiments of the present disclosure are not limited thereto.

[0232] The second plate 1610' may be disposed on the first plate 1610. The second plate 1610' may be a yoke, but embodiments of the present disclosure are not limited thereto. One or more of the first plate 1610 and the second plate 1610' may be formed of a magnetic material such as iron (Fe), but embodiments of the present disclosure are not limited thereto.

[0233] The frame 1640 may be disposed outside around the second plate 1610'. The damper 1670 may be disposed between the frame 1640 and the bobbin 1650. The frame 1640 according to some embodiments of the present disclosure may be disposed at the front edge of the second plate 1610' to have a specific height and the same shape as the bobbin 1650. According to another embodiment of the present disclosure, the frame 1640 may include a hollow portion disposed at the front edge of the second plate 1610' to have a specific height and the same shape as the bobbin 1650.

[0234] The damper 1670 may be connected between the frame 1640 and the vibration device. For example, the damper 1650 may be connected between the frame 1640 and the bobbin 1650. The damper 1670 may be referred to as a bracket, a suspension, or an edge, but the embodiments of the present disclosure are not limited thereto.

[0235] One end or a portion of the damper 1670 according to some embodiments of the present disclosure may be connected to the frame 1640, and the other end or another portion of the damper 1670 may be connected to the upper outer surface of the bobbin 1650. The damper 1670 may have a pleated structure between one end and the other end thereof, and may contract and relax based on the vertical movement of the bobbin 1650 to control the vibration of the bobbin 1650. The damper 1670 may be connected between the bobbin 1650 and the frame 1640, and may limit the vibration distance of the bobbin 1650 using a restoring force. For example, when the bobbin 1650 vibrates a specific distance or more or vibrates a specific distance or less, the bobbin 1650 may be restored to the original position by the restoring force of the damper 1670.

[0236] One or more vibration devices 500 according to some embodiments of the present disclosure may also include a bobbin ring 1652 .

[0237] The bobbin ring 1652 may be provided on the front surface (or front end portion) of the bobbin 1650. The bobbin ring 1652 may transmit the rising and falling motion (or vibration) of the bobbin 1650 to the rear surface of the display device 100. The bobbin ring 1652 according to some embodiments of the present disclosure may have a ring shape provided at the front surface of the bobbin 1650, a disc shape (or a circular plate shape) covering the entire front surface of the bobbin 1650, or a hat shape surrounding the front surface and upper outer surface of the bobbin 1650, but the shape is not limited thereto. For example, the bobbin ring 1652 may be referred to as a bobbin protection member, but embodiments of the present disclosure are not limited thereto.

[0238] In the display apparatus according to one embodiment of the present disclosure, the display device 100 may further include a heat dissipation member 102 .

[0239] The heat dissipation member 102 may be disposed at the rear surface of the display device 100. For example, the heat dissipation member 102 may be disposed between one or more vibration devices 500 and the display device 100. The heat dissipation member 102 according to one embodiment of the present disclosure may be attached at the rear surface of the display device 100 to overlap with the vibration device 500. The first adhesive member 401 may be disposed between the heat dissipation member 102 and the display device 100. For example, the first adhesive member 401 may be disposed between the heat dissipation member 102 and the display panel 110. For example, the heat dissipation member 102 may be attached to the display panel 110 through the first adhesive member 401. For example, the heat dissipation member 102 may be attached to the rear surface of the display panel 110 through the first adhesive member 401. The first adhesive member 401 may include one or more of a double-sided tape, a double-sided foam tape, a double-sided pad, a double-sided foam pad, a single-sided tape, a single-sided foam tape, a single-sided pad, a single-sided foam pad, an adhesive, and a bonding agent, but the embodiments of the present disclosure are not limited thereto. The second adhesive member 403 may be disposed between the heat dissipation member 102 and the vibration device 500. For example, the heat dissipation member 102 may be attached to the vibration device 500 via the second adhesive member 403. For example, the second adhesive member 403 may be disposed between the heat dissipation member 102 and the bobbin ring 1652. The heat dissipation member 102 may be attached to the bobbin ring 1652 via the second adhesive member 403. The second adhesive member 403 may include one or more of a double-sided tape, a double-sided foam tape, a double-sided pad, a double-sided foam pad, a single-sided tape, a single-sided foam tape, a single-sided pad, a single-sided foam pad, an adhesive, and a bonding agent, but the embodiments of the present disclosure are not limited thereto. FIG. 3A to FIG. 3C As shown, the second adhesive member 403 may be formed at a portion on which the heat dissipation member 102 is attached. However, the present disclosure is not limited thereto, and the second adhesive member 403 may be formed on the entire rear surface of the display panel 110 or the heat dissipation member 102. For example, the second adhesive member 403 may be formed on the entire surface between the rear surface of the heat dissipation member 102 or the rear surface of the display panel 110 and the vibration device 500. For example, the second adhesive member 403 may be formed at the entire surface between the rear surface of the heat dissipation member 102 or the rear surface of the display panel 110 and the bobbin ring 1652.

[0240] Since the heat dissipation member 102 is disposed at the rear surface of the display device 100 to overlap with the vibration device 500, the heat generated when the vibration device 500 is driven can be diffused toward the display device 100, thereby preventing the performance of the vibration device 500 from being reduced due to the heat. In addition, the heat dissipation member 102 can have a size relatively larger than or equal to the vibration device 500 with respect to the central portion of the vibration device 500, and thus, the heat generated when the vibration device 500 is driven can be diffused to a wider area, thereby preventing the heat from being concentratedly transferred to the local area of ​​the display device 100 overlapping with the vibration device 500. Therefore, the local uneven brightness of the display device 100 can be prevented or minimized.

[0241] According to some embodiments of the present disclosure, the heat dissipation member 102 may include a metal material having high thermal conductivity, and may include, for example, one of aluminum (Al), copper (Cu), silver (Ag), and magnesium (Mg) or an alloy thereof, but the embodiments of the present disclosure are not limited thereto. The heat dissipation member 102 may be referred to as other terms, such as a heat diffusion member, a heat diffusion sheet, a heat diffusion layer, a heat diffusion plate, a heat sink, a heat sink, or a heat dissipation plate, but the embodiments of the present disclosure are not limited thereto.

[0242] Reference Figure 3A , one or more vibration devices 500 may further include a diameter expansion portion 1614. For example, the diameter expansion portion 1614 and the first plate 1610 may be provided as one body. For example, the diameter expansion portion 1614 may be formed integrally with the first plate 1610. The first plate 1610 of the vibration device 500 may not have a cylindrical shape or a cylindrical shape. One side of the first plate 1610 may include a protrusion having a diameter greater than that of other parts of the first plate 1610. The protrusion region having an enlarged diameter may be referred to as the diameter expansion portion 1614. The diameter expansion portion 1614 may have an annular shape. An expansion portion 1612 for arranging the vibration device 500 may be formed at a portion of the diameter expansion portion 1614.

[0243] The fourth connection member 333 may be provided at the expansion portion 1612. The fourth connection member 333 may include a screw 1720 and a nut 1730. For example, the nut 1730 may be provided in the support member 300. One or more vibration devices 500 may be coupled to the second support member 350 by the nut 1730 and the screw 1720. Therefore, the vibration device 500 may be accommodated in the support hole 350S provided at the second support member 350.

[0244] Nut 1730 may be, for example, a self-clinching nut. Examples of self-clinching nuts may include When the self-locking nut is used, the vibration generated by the vibration device 500 can be absorbed by a portion of the self-locking nut (ie, the nut 1730), and thus, the vibration transmitted to the support member 300 can be reduced.

[0245] exist FIG. 3A to FIG. 3C In the embodiment of the present invention, an example in which the support member 300 includes the first support member 310 and the second support member 350 is described, but the embodiments of the present disclosure are not limited thereto. For example, the support member 300 may include only the second support member 350 .

[0246] Figure 3B Shows a thickness less than Figure 3A The vibration device of the vibration device.

[0247] Reference Figure 3B , the fourth connection member 333 may be provided at the vibration device 500 so as to place the vibration device 500 inside (or inside space) of the display device. The first plate 1610 may include an extension 1612. The fourth connection member 333 may be provided at the extension 1612 of the first plate 1610. For example, a tap may be formed by increasing the thickness of the first plate 1610, and then, screwing may be performed. Examples of taps may include manual taps, machine taps, pipe thread taps, and standard taps, but embodiments of the present disclosure are not limited thereto. For example, the fourth connection member 333 may be provided in the support member 300. For example, the fourth connection member 333 may be provided in the first support member 310. The fourth connection member 333 may include a screw 1720 and a nut 1730. The screw 1720 and the nut 1730 may be provided in the support member 300, and the vibration device 500 may be provided in the support member 300 by the screw 1720 and the nut 1730. For example, the nut 1730 may be a self-locking nut. Examples of self-locking nuts may include Nut, but the embodiments of the present disclosure are not limited thereto.

[0248] The vibration device 500 can be connected to the support member 300 by a press-fit scheme (or an indentation method) through a nut 1730 without a support hole of the support member 300 (e.g., the second support member 350). The press-fit scheme can use a sawtooth press-fit scheme, but the embodiments of the present disclosure are not limited to the connection scheme or shape. Therefore, the vibration device 500 can be arranged inside the display device. For example, the vibration device 500 can be arranged between the display panel 110 and the support member 300 by the fourth connecting member 333. Therefore, the vibration device can be arranged inside the display device, and therefore, the support hole of the support member can not be arranged, thereby preventing particles from penetrating through the support hole of the support member from the outside. In addition, the vibration device may not be exposed at the rear surface of the support member, and therefore, a display device with an aesthetic appearance can be provided, thereby preventing damage to the vibration device. In addition, the vibration device can be arranged inside the display device, and therefore, the sound of the low-pitched vocal cords of the vibration device can be better enhanced.

[0249] Reference Figure 3C , the fourth connection member 333 may be provided in the vibration device 500 so as to place the vibration device 500 inside the display device. The frame 1640 may include an extension 1642. The fourth connection member 333 may be provided at the extension 1642 of the frame 1640. The fourth connection member 333 may include a screw 1720 and a nut 1730. The screw 1720 and the nut 1730 may be provided in the support member 300, and the vibration device 500 may be provided at the support member 300 by the screw 1720 and the nut 1730. For example, the nut 1730 may be a self-locking nut. Examples of self-locking nuts may include Nut, but the embodiments of the present disclosure are not limited thereto.

[0250] For example, the vibration device 500 can be connected to the support member 300 by a press-fit scheme (or an indentation method) through a nut 1730 without a support hole of the support member 300. The press-fit scheme can use a sawtooth press-fit scheme, but the embodiments of the present disclosure are not limited to the connection scheme or shape. Therefore, the vibration device 500 can be arranged inside the display device. For example, the vibration device 500 can be arranged between the display panel 110 and the support member 300 by the fourth connecting member 333. Therefore, the vibration device can be arranged inside the display device, and therefore, the support hole of the support member can not be set, thereby preventing particles from penetrating through the support hole of the support member from the outside. In addition, the vibration device may not be exposed to the rear surface of the support member, and therefore, a display device with an aesthetic appearance can be provided, thereby preventing damage to the vibration device. In addition, the vibration device can be arranged inside the display device, and therefore, the sound of the low-pitched vocal cords of the vibration device can be better enhanced.

[0251] Figure 4 It is along Figure 1 Another cross-sectional view taken along line II' is shown.

[0252] Reference Figure 1 and Figure 4 , a display device according to an embodiment of the present disclosure may include a display device 100, a support member 300, and one or more vibration devices 500. The description of the display device 100, the display panel 110, the support member 300, and the middle frame 700 is the same as that of the above reference Figure 1 and Figure 2 The description given is the same, and thus, a repeated description of elements other than the partition and elements related thereto may be omitted or will be briefly given.

[0253] According to one embodiment of the present disclosure, one or more vibration devices 500 may be arranged at a structure 510 arranged at a support member 300. The one or more vibration devices 500 arranged at the structure 510 to vibrate the display device 100 may be a monomer structure or a single structure modularized as one element (or one component). For example, the structure 510 and the one or more vibration devices 500 may be manufactured as a finished product (finished product), such as a monomer structure or a single structure, by a modular process (or assembly process) rather than an assembly process performed on a display device. After the structure 510 and the one or more vibration devices 500 are manufactured as finished products, the gap space GS between the display device 100 and the support member 300 may be installed or arranged by a relatively simple element (or component) installation (or placement) process in the assembly process performed on the display device. Therefore, in a display device according to one embodiment of the present disclosure, the assembly of the one or more vibration devices 500 may be improved in the process of assembling the module, thereby improving productivity.

[0254] According to some embodiments of the present disclosure, the first support member 310 and the second support member 350 may be coupled or connected to each other by a connecting member 330. For example, the connecting member 330 may be an adhesive resin, a double-sided tape, or a double-sided adhesive foam pad. The connecting member 330 may have elasticity for absorbing impact.

[0255] According to some embodiments of the present disclosure, the connection member 330 may be provided at the entire region between the first support member 310 and the second support member 350 .

[0256] According to some embodiments of the present disclosure, the connection member 330 may be provided in a mesh structure including an air gap between the first support member 310 and the second support member 350. For example, a portion of the air gap between the first support member 310 and the second support member 350 may be used as a setting area for a signal transmission member or a cable connected to the vibration device 500.

[0257] One or more vibration devices 500 may generate sound PVS using the display device 100 as a vibration plate. For example, one or more vibration devices 500 may generate sound PVS using the display panel 110 as a vibration plate.

[0258] The display apparatus according to some embodiments of the present disclosure may include one or more vibration devices 500 disposed at a rear center portion (or a central area) of the display device 100. For example, the one or more vibration devices 500 may vibrate the rear center portion of the display device 100 to generate a sound PVS toward a forward direction (FD) of the display device 100 based on the vibration of the display device 100.

[0259] According to another embodiment of the present disclosure, the display device may include a first vibration device 500-1 disposed at a first area (or left area) of the display device 100 and a second vibration device 500-2 disposed at a second area (or right area) of the display device 100, relative to the rear center portion of the display device 100. For example, the first vibration device 500-1 may vibrate the first rear area of ​​the display device 100 to generate a sound PVS based on the vibration of the first area of ​​the display device 100. The second vibration device 500-2 may vibrate the second rear area of ​​the display device 100 to generate a sound PVS based on the vibration of the second area of ​​the display device 100. The display device according to another embodiment of the present disclosure may output a two-channel sound based on the left and right sound separation of the first vibration device 500-1 and the second vibration device 500-2. For example, the first vibration device 500-1 may be configured to output a left sound, and the second vibration device 500-2 may be configured to output a right sound.

[0260] According to some embodiments of the present disclosure, one or more vibration devices 500 may be located between the display device 100 and the support member 300, and may vibrate the display device 100 to generate sound PVS. The rear surface of the one or more vibration devices 500 may be covered by the support member 300, and thus may be hidden and not directly exposed at the outermost rear surface of the display device. Therefore, since the rear surface of at least one vibration device 500 is covered by the support member 300, the display device according to one embodiment of the present disclosure may have a simple back design, wherein the rear surface or a portion of the at least one vibration device 500 is not exposed or not seen by the user's eyes, thereby improving the rear appearance design.

[0261] According to some embodiments of the present disclosure, the structure 510 provided at the support member 300 and the one or more vibration devices 500 provided at the structure 510 to vibrate the display device 100 may be a monolithic structure or a single structure modularized into one element (or one component). For example, one or more vibration devices 500 may be manufactured as a finished product type, such as a monolithic structure or a single structure, through a modularization process (or assembly process) rather than an assembly process performed on a display device, and then, at least one vibration device 500 may be installed or provided in the gap space GS between the display device 100 and the support member 300 through a relatively simple element (or component) installation (or placement) process in the assembly process performed on the display device. Therefore, in a display device according to one embodiment of the present disclosure, the assembly of one or more vibration devices 500 may be improved in the process of assembling modules, thereby improving productivity.

[0262] One or more vibration devices 500 according to one embodiment of the present disclosure may directly or indirectly vibrate the display device 100. For example, one or more vibration devices 500 may be directly connected to the display panel 110, and may directly vibrate the display panel 110. As another embodiment of the present disclosure, one or more vibration devices 500 may indirectly vibrate the display panel 110 by a vibration transfer member directly connected to the display panel 110. For example, the vibration transfer member may be implemented in the corresponding vibration device 500 or the display device 100. For example, the vibration transfer member implemented in the one or more vibration devices 500 may be a vibration transfer plate (or vibration transfer sheet) contacting (or coupled to) the display device 100. In addition, the vibration transfer member implemented in the display device 100 may be a backlight module disposed at the rear surface of the display panel 110, or may be a vibration transfer plate (or heat sink plate) coupled to (or attached to) the rear surface of the display panel 110.

[0263] Therefore, a display device according to one embodiment of the present disclosure can output sound PVS to the forward area FD based on the vibration of the display device 100 (e.g., the display panel 110) caused by the vibration of one or more vibration devices 500 arranged between the display device 100 and the supporting member 300, thereby enhancing the immersive experience of the viewer watching the image displayed by the display device.

[0264] Furthermore, in the display apparatus according to one embodiment of the present disclosure, since the sound PVS is generated based on the vibration of the display device 100 , a separate speaker may not be provided, thereby enhancing the degree of freedom in design of the set and arrangement of components.

[0265] In addition, since the vibration device 500 is disposed in the gap space GS between the display device 100 and the support member 300, the rear surface of the vibration device 500 can be covered by the support member 300, and therefore, the display device according to one embodiment of the present disclosure can have a simple back design, in which the rear surface or a portion of the vibration device 500 is not exposed or visible to the user, thereby improving the rear appearance design of the display device.

[0266] In addition, in a display device according to one embodiment of the present disclosure, the structure 510 and the vibration device 500 can be modularized into one element and can be installed at the gap space GS between the display device 100 and the supporting member 300 through a relatively simple element installation process. Therefore, the assembly of the vibration device 500 can be improved in the assembly process performed on the display device, thereby improving productivity.

[0267] FIG. 5A to FIG. 5E A vibration device according to one embodiment of the present disclosure is shown.

[0268] Reference Figures 4 to 5E , a vibration generating device 501 according to one embodiment of the present disclosure may include a structure 510 and a vibration device 500 .

[0269] The structure 510 may be disposed at the support member 300. For example, the structure 510 may be disposed at the support member 300 and may fix or support the vibration device 500. According to some embodiments of the present disclosure, the structure 510 may be a metal plate including a metal material and having a plate shape. The structure 510 may be referred to as a support structure, a module structure, a plate mechanism, a base structure, a base mechanism, a module support frame, or a module support plate, but embodiments of the present disclosure are not limited thereto.

[0270] The structure 510 may be disposed on or fixed to the support member 300 through the first member 410 (or module member). The rear surface of the structure 510 may be covered by the support member 300, and thus may be hidden and not directly exposed at the outermost rear surface of the display device. For example, the rear surface of the structure 510 may be completely covered by the support member 300, and thus may be hidden and not directly exposed at the outermost rear surface of the display device.

[0271] The first member 410 according to some embodiments of the present disclosure may be a double-sided adhesive member between the structure 510 and the support member 300.

[0273] According to some embodiments of the present disclosure, the double-sided adhesive member as the first member 410 may further include a heat transfer material. The heat transfer material may quickly transfer the heat generated in the vibration generating device 501 to the support member 300, and thus the heat of the vibration generating device 501 may be dissipated toward the support member 300, thereby preventing or minimizing the local brightness non-uniformity of the display device 100 caused by the heat generated when the vibration generating device 501 is driven being locally transferred to the area of ​​the display device 100 overlapping with the vibration generating device 501. According to some embodiments of the present disclosure, the heat transfer material may include conductive particles or a conductive layer, but the embodiments of the present disclosure are not limited thereto. For example, the double-sided adhesive member including the heat transfer material may be referred to as a heat transfer tape or a heat dissipation tape, but the embodiments of the present disclosure are not limited thereto.

[0274] The vibration device 500 may be disposed at the structure 510 and may vibrate the display device 100. For example, the vibration device 500 may be disposed at the structure 510 and may vibrate the display panel 110. The integrated member 520 may be disposed between the vibration device 500 and the structure 510.

[0277] The bottom plate 531 may be disposed at or fixed to the structure 510, and may be a main body of the vibration device 500. The bottom plate 531 may support one or more of the magnet 532, the central magnetic pole 533, and the edge frame 536. The bottom plate 531 may include a metal material having magnetism, such as iron (Fe). The bottom plate 531 may be referred to as a lower plate, a chassis, or a yoke, but embodiments of the present disclosure are not limited thereto.

[0278] The bottom plate 531 may include a groove portion accommodating the magnet 532 and the bobbin 534. For example, the groove portion may be concavely provided from the upper surface of the bottom plate 531 to have a circular shape.

[0279] The integrated component 520 may be disposed between the bottom plate 531 and the structure 510. For example, the bottom plate 531 may be integrally provided with the structure 510 through the integrated component 520, or may be provided at the structure 510.

[0280] The integrated member 520 may be an adhesive member. The adhesive member may be disposed between the extension portion (or placement portion) 531a of the bottom plate 531 and the structure 510, and thus the bottom plate 531 may be disposed at the structure 510. The integrated member 520 may be an adhesive or a double-sided tape, but the embodiments of the present disclosure are not limited thereto.

[0281] According to another embodiment of the present disclosure, the integration member 520 may include a plurality of screws. The plurality of screws may pass through the expansion portion 531 a of the bottom plate 531 and may be fastened to the structure 510 , and thus, the bottom plate 531 may be disposed at the structure 510 .

[0282] According to another embodiment of the present disclosure, the integrated component 520 may include a bolt and a nut. The nut may overlap with the extension 531a of the bottom plate 531 and be disposed on or fixed to the structure 510. The bolt may pass through the extension 531a of the bottom plate 531 and may be fastened to the nut. The nut according to some embodiments of the present disclosure may be a self-locking nut disposed at the structure 510, but the embodiments of the present disclosure are not limited thereto. The self-locking nut may be Nut.

[0283] The magnet 532 , the central magnetic pole 533 , the bobbin 534 , and the coil 535 may be referred to as a magnetic circuit portion or a magnetic vibration portion, which is mounted on the bottom plate 531 to vibrate the display device 100 .

[0284] The magnetic circuit portion according to some embodiments of the present disclosure may have an external or dynamic magnetic type structure in which the magnet 532 is arranged outward from the coil 535, or may have an internal magnetic type or micro structure in which the magnet 532 is arranged inward from the coil 535. The vibration device 500 including the magnetic circuit portion having the internal magnetic type structure may have an overall smaller size and extremely low leakage flux. The vibration device 500 according to some embodiments of the present disclosure may have an external magnetic type or an internal magnetic type structure. Hereinafter, an example in which the vibration device 500 has an internal magnetic type will be described. The description of the magnet 532, the central magnetic pole 533, the bobbin 534, and the damper 537 may be the same as that described above with reference to FIG. 3A to FIG. 3C Descriptions given are the same or similar, and thus, duplicate descriptions thereof may be omitted or briefly given.

[0285] The magnet 532 according to some embodiments of the present disclosure may be inserted or accommodated in the groove portion of the bottom plate 531. The magnet 532 may be a permanent magnet that can be inserted or accommodated in the bobbin 534. For example, the magnet 532 may be a permanent magnet having a cylindrical shape that can be inserted or accommodated in the bobbin 534.

[0286] The bobbin 534 according to some embodiments of the present disclosure may be disposed on the bottom plate 531 and surround the magnet 532. The central magnetic pole 533 may be received or inserted in the bobbin 534 and may guide the rise or fall of the bobbin 534. The central magnetic pole 533 may be referred to as a lifting guide or a pole piece, but embodiments of the present disclosure are not limited thereto.

[0287] The edge frame 536 may be provided at the front edge (or front periphery) of the bottom plate 531, and may support the damper 537. The edge frame 536 according to some embodiments of the present disclosure may be provided at the front edge of the bottom plate 531 to have a specific height and the same shape as the bobbin 534. According to another embodiment of the present disclosure, the edge frame 536 may include a hollow portion provided at the front edge of the bottom plate 531 to have a specific height and the same shape as the bobbin 534.

[0288] The damper 537 may be disposed or connected between the edge frame 536 and the magnetic circuit portion. For example, the damper 537 may be disposed or connected between the edge frame 536 and the bobbin 534. The damper 537 may be referred to as a bracket, a suspension, or an edge, but the embodiments of the present disclosure are not limited thereto.

[0289] Since the vibration device 500 is disposed between the display device 100 and the support member 300, the vibration device 500 should have a thinner thickness to reduce the thickness of the display device thinner or make the display device slim, thereby, when the height (or thickness) of the bobbin 534 is reduced, the sound pressure level may be reduced. Therefore, in order to solve the problem of reduced sound pressure level due to the reduced height of the bobbin 534, the inventors have designed a structure in which the area of ​​the damper 537 disposed near the bobbin 534 is wider. When the area of ​​the damper 537 increases, the inventors have realized that the space in which the line for applying current to the coil 535 is provided becomes narrower, resulting in interference between the line and the damper 537. Therefore, through various experiments, the inventors have configured a damper 537 formed by a conductor and performing the function of a line.

[0290] The damper 537 according to some embodiments of the present disclosure may include a metal material electrically connected to the coil 535. For example, the damper 537 may be formed of stainless steel or copper (Cu), but embodiments of the present disclosure are not limited thereto.

[0291] The vibration device 500 according to some embodiments of the present disclosure may further include a bobbin protection member 538 .

[0292] The bobbin protection member 538 may be provided at the front surface (or front end portion) of the bobbin 534, and may transmit the ascending and descending motion (or vibration) of the bobbin 534 to the rear surface of the display device 100. The bobbin protection member 538 according to some embodiments of the present disclosure may have a ring shape provided on the front surface of the bobbin 534, a disc shape covering the entire front surface of the bobbin 534, or a cap shape surrounding the front surface and upper outer surface of the bobbin 534, but the shape is not limited thereto. For example, the bobbin protection member 538 may be called a bobbin ring, but embodiments of the present disclosure are not limited thereto.

[0293] The vibration generating device 501 according to one embodiment of the present disclosure may further include a connecting member 550 .

[0294] The connecting member 550 may be disposed between the structure 510 and the display device 100. The connecting member 550 according to some embodiments of the present disclosure may be disposed between the front edge portion (or front peripheral portion) of the structure 510 and the rear edge portion (or rear peripheral portion) of the display device 100. For example, the connecting member 550 may be a double-sided tape or a double-sided foam tape, but the embodiments of the present disclosure are not limited thereto. The connecting member 550 may provide a vibration space around the vibration device 500 between the structure 510 and the display device 100. The vibration space may be referred to as a sound pressure level space, a sound space, a sound box, a sound portion, a resonance box, or a resonance portion, but the embodiments of the present disclosure are not limited thereto.

[0295] The vibration generating device 501 according to one embodiment of the present disclosure may further include a vibration transferring member 570 .

[0296] The vibration transferring member 570 may be connected or coupled to each of the connection member 550 and the vibration device 500 , and may vibrate based on the vibration of the vibration device 500 to transfer the vibration of the vibration device 500 to the display device 100 .

[0297] According to some embodiments of the present disclosure, the rear edge portion or the rear peripheral portion of the vibration transfer member 570 can be connected or coupled to the connecting member 550, and the rear central portion of the vibration transfer member 570 can be connected to the front surface of the bobbin 534 of the vibration device 500, or can be connected or coupled to the bobbin protection member 538 of the vibration device 500.

[0298] The vibration transfer member 570 according to some embodiments of the present disclosure may be formed of one or more materials of aluminum (Al), magnesium (Mg), Mg alloy, Mg-lithium (Li) alloy and Al alloy, but the embodiments of the present disclosure are not limited thereto. For example, the magnesium alloy may include one or more materials of aluminum (Al), zinc (Zn) and manganese (Mn). The magnesium alloy may be the lightest material among the metal materials used as the speaker vibration plate, may have a relatively high non-rigidity (rigidity / specific gravity) and a relatively high vibration damping capacity (ability to absorb and gradually reduce vibration), and may have good dimensional stability relative to temperature changes and the passage of time.

[0299] According to some embodiments of the present disclosure, the second member 430 (or module bonding member) may be disposed between the vibration transfer member 570 and the display device 100. For example, the front surface of the vibration transfer member 570 may be coupled or connected to the rear surface of the display device 100 through the second member 430.

[0300] The second member 430 may be a double-sided adhesive member between the display device 100 and the vibration transfer member 570. The double-sided adhesive member may be a double-sided tape or a double-sided foam tape, but the embodiments of the present disclosure are not limited thereto. One surface (or front surface) of the second member 430 may be disposed on the rear surface of the display device 100 or coupled to the rear surface of the display device 100, and the other surface (or rear surface) of the second member 430 may be disposed on the front surface of the vibration transfer member 570 or coupled to the front surface of the vibration transfer member 570. For example, one surface of the second member 430 may be disposed on or fixed to the rear surface of the display device 100 in a state where the upper protective sheet is peeled off.

[0301] According to some embodiments of the present disclosure, in order to facilitate assembly between the vibration generating device 501 and the display device 100, the second member 430 may be coupled (or modularized) to the uppermost surface of the vibration generating device 501 modularized as one element, and may be protected by an upper protective sheet. For example, the upper protective sheet may be referred to as an upper peeling sheet or a top liner (or upper liner), but embodiments of the present disclosure are not limited thereto.

[0302] For example, all of the vibration transfer members 570 and the second member 430 may be omitted. For example, the vibration generating device 501 may include an upper protective sheet coupled or connected to each of the connecting member 550 and the vibration device 500. The upper protective sheet may be coupled or connected to each of the connecting member 550 and the vibration device 500 to cover the entire front surface of the vibration generating device 501, and thus, in a transfer process after a modularization process is performed on the vibration generating device 501 modularized into one element, each of the vibration device 500 and the connecting member 550 of the vibration generating device 501 may be prevented from being exposed to the outside, and particles such as dust may be prevented from penetrating into the vibration generating device 501. The upper protective sheet may be peeled off from the vibration generating device 501 immediately before the assembly process between the vibration generating device 501 and the display device 100.

[0303] Therefore, the vibration generating device 501 according to one embodiment of the present disclosure can be arranged between the display device 100 and the supporting member 300 in a state where the structure 510 and the vibration device 500 are modularized into one element. Therefore, through the display device 100 as a vibration plate, the sound PVS based on the vibration of the display panel 110 can be output, and the outermost rear surface of the display device may not expose the vibration generating device 501, thereby improving the rear appearance design of the display device.

[0304] Reference Figure 5B and Figure 5C , the adhesive member 522 can be arranged between the vibration device 500 and the structure 510. The adhesive member 522 may include one or more of a double-sided tape, a double-sided foam tape, a double-sided pad, a double-sided foam pad, a single-sided tape, a single-sided foam tape, a single-sided pad, a single-sided foam pad, an adhesive and a bonding agent, but the embodiments of the present disclosure are not limited thereto. Compared with screws or nuts and bolts, when the adhesive member 522 is provided, the assembly process can be simplified, and the extension of the hole or plate for fastening with the screws or nuts and bolts may not be required, thereby providing a thinner vibration device. The description of the vibration device is the same as that of the above reference. FIG. 3A to FIG. 3C and Figure 5A The descriptions given are the same, and therefore, their repeated descriptions may be omitted.

[0305] Reference Figure 5B , the vibration device 500 can be asymmetrically arranged. When the vibration device 500 is asymmetrically arranged, the dip phenomenon of a specific frequency can be reduced. For example, when standing waves appear in the upper part, the lower part, the left part and the right part relative to the vibration device 500, the dip phenomenon may occur in the upper part, the lower part, the left part and the right part, but when the vibration device 500 is asymmetrically arranged, the phenomenon that the standing waves appear in the upper part, the lower part, the left part and the right part at the same time can be reduced. Therefore, the dip phenomenon can be reduced, and thus the sound characteristics can be better enhanced.

[0306] Reference Figure 5D and Figure 5E , the support member 300 may include a first support member 310 and a second support member 350. The description of the first support member 310 and the second support member 350 is the same as that of the above reference Figure 2 The descriptions given are the same, and therefore, their repeated descriptions may be omitted.

[0307] Reference Figure 5D , the vibration device 500 may be accommodated in the first support member 310. For example, the vibration device 500 may be disposed at the removed portion of the first support member 310. The vibration device 500 may be attached to the second support member 350 by an adhesive member 522. The adhesive member 522 may be disposed between the vibration device 500 and the second support member 350. The first support member 310 and the vibration device 500 may be attached by an adhesive member 522. As another embodiment of the present disclosure, the adhesive member 522 may also be disposed between the vibration device 500 and the first support member 310. For example, the adhesive member 522 may also be disposed between the extension portion 531a of the bottom plate 531 and the first support member 310. The adhesive member 522 may include one or more of a double-sided tape, a double-sided foam tape, a double-sided pad, a double-sided foam pad, a single-sided tape, a single-sided foam tape, a single-sided pad, a single-sided foam pad, an adhesive, and a bonding agent, but embodiments of the present disclosure are not limited thereto. A portion of the first support member 310 may be removed, and the vibration device 500 may be disposed at the removed region of the first support member 310, and thus, the thickness of the vibration device 500 may be reduced, thereby reducing the thickness of the display device. In addition, when the vibration device 500 is disposed adjacent to the first support member 310 and / or the second support member 350, abnormal vibration may occur when the vibration device 500 vibrates, and thus, the vibration device 500 may be spaced apart from the first support member 310 and / or the second support member 350 by a certain interval or distance D. For example, the vibration device 500 may be spaced apart from the first support member 310 and / or the second support member 350 by the interval or distance D. For example, the interval or distance D may be 1 mm or more, but embodiments of the present disclosure are not limited thereto.

[0308] Reference Figure 5E, the vibration device 500 may be accommodated between the first support member 310 and between the second support member 350. For example, the bottom plate 531 of the vibration device 500 may have an external appearance. The bottom plate 531 of the vibration device 500 may be disposed between the first support member 310 and between the second support member 350. The bottom plate 531 of the vibration device 500 may be configured to penetrate the first support member 310 and the second support member 350. The adhesive member 522 may be disposed between the vibration device 500 and the first support member 310. For example, the adhesive member 522 may be disposed at the extension 531a of the bottom plate 531 and on one side of the first support member 310. The adhesive member 522 may include one or more of a double-sided tape, a double-sided foam tape, a double-sided pad, a double-sided foam pad, a single-sided tape, a single-sided foam tape, a single-sided pad, a single-sided foam pad, an adhesive, and a bonding agent, but embodiments of the present disclosure are not limited thereto. Since the bottom plate 531 of the vibration device 500 is configured to have an external appearance, the thickness of the vibration device 500 can be reduced, thereby reducing the thickness of the display device. In addition, when the vibration device 500 is disposed adjacent to the first support member 310 and the second support member 350, abnormal vibration may occur when the vibration device 500 vibrates, and therefore, the vibration device 500 may be spaced apart from the first support member 310 and the second support member 350 by a certain interval or distance D. For example, the vibration device 500 may be spaced apart from the first support member 310 and the second support member 350 by the interval or distance D. For example, the interval or distance D may be 1 mm or more, but embodiments of the present disclosure are not limited thereto.

[0309] One or more vibration devices 500 can realize dual-channel sound including left sound and right sound, therefore, the inventor has recognized that it is difficult to reproduce or generate sound in the upper and lower parts. For example, multi-channel sound can be reproduced by a sound bar, but the upper channel may be an indirect sound produced by reproducing sound through reflection of the ceiling, therefore, the inventor has recognized that there is a problem that it is difficult to reproduce the desired sound due to the position difference between the displayed picture and the sound image. Therefore, the inventor has conducted various experiments to reproduce real sound instead of indirect sound. Through various experiments, the inventor has invented a display device with a new structure for realizing real sound and multi-channel sound. This will be described below.

[0310] FIG. 6A to FIG. 6B A display device including a vibration device according to one embodiment of the present disclosure is shown.

[0311] Reference Fig. 6A and Figure 6B, the display device may include a display device 100, the display device 100 includes a display panel 110, the display panel 110 displays an image and includes a first area (1), a second area (2), a third area (3), a fourth area (4), a fifth area (5) and a sixth area (6). For example, the rear surface of the display device 100 may include a first area (1) to a sixth area (6). The first area (1), the second area (2) and the third area (3) may be arranged at an upper portion of the display device 100. For example, the third area (3) may be arranged between the first area (1) and the second area (2). The fourth area (4) to the sixth area (6) may be arranged at a lower portion of the first area (1) to the third area (3). For example, the sixth area (6) may be arranged between the fourth area (4) and the fifth area (5).

[0312] At least one or more vibration devices may be disposed at at least one or more of the first region (1) to the sixth region (6). In the following embodiments, an example in which the vibration device is disposed at the rear surface of the display device 100 (e.g., the rear surface of the display panel 110) will be described, but the embodiments of the present disclosure are not limited thereto. For example, the vibration device may be disposed between the display panel 110 and the support member 300. For example, the vibration device may be disposed between the rear surface of the display panel 110 and the upper surface of the support member 300. As another embodiment of the present disclosure, FIG. 5A to FIG. 5E As shown, the vibration device can be configured to be modularized into one element (or one component).

[0313] According to some embodiments of the present disclosure, the display device may further include a partition. For example, the partition may be disposed between the display panel 110 and the support member 300. The partition may be an air gap or space that generates sound when the display panel 110 is vibrated by a vibration device. The air gap or space that generates or outputs sound may be referred to as a partition. The partition may separate the sound or may separate the sound channel, thereby preventing or reducing the occurrence of nontransparent sound caused by the interference of the sound. The partition may be referred to as a housing or a baffle, but the embodiments of the present disclosure are not limited thereto. In the following embodiments, an example in which the partition is disposed at the support member will be described. However, the embodiments of the present disclosure are not limited thereto, and the partition may be disposed at the rear surface of the display panel. In order to illustrate the vibration device and the partition, an example in which the vibration device and the partition are disposed at the support member will be described. For example, when the partition is disposed at the support member, the adverse effect on the image quality of the display panel caused by the partition disposed at the display panel may be reduced.

[0314] Reference Fig. 6A, a partition may be provided to separate the left sound and the right sound output by the vibration device provided at the rear surface of the display panel 110. For example, the partition may be provided between the display panel 110 (corresponding to the first area (1) to the sixth area (6) of the display panel 110) and the support member 300. For example, the first partition 1711 may be provided between the first area (1) and the third area (3). The second partition 1712 may be provided between the second area (2) and the third area (3). The third partition 1721 may be provided between the fourth area (4) and the sixth area (6). The fourth partition 1722 may be provided between the fifth area (5) and the sixth area (6). For example, the first partition 1711 and the second partition 1712 may separate the left and right channels or the left and right sounds generated by the first vibration device 500HL and the second vibration device 500HR. For example, the third partition 1721 and the fourth partition 1722 may separate the left and right channels or the left and right sounds generated by the third vibration device W1 and the fourth vibration device W2.

[0315] The first vibration device 500HL and the second vibration device 500HR may also be configured to implement multi-channel sound, and the partition should be configured to separate the channel or sound generated by the first vibration device 500HL and the second vibration device 500HR from the channel or sound generated by the third vibration device W1 and the fourth vibration device W2. When the first partition 1711 to the fourth partition 1722 are provided, the left and right sounds or the left and right channels may be separated from each other. The partition for generating sound in each vibration device should be configured to separate the upper sound or the upper channel from the lower sound or the lower channel, and the vibration device provided at the area of ​​the rear surface of the display panel 110 implements independent sound for each area.

[0316] The partition may be configured to separate an upper channel or a height channel of the display panel 110 from a center channel of the display panel 110. For example, the fifth partition 1731 may separate an upper channel or a height channel of the display panel 110 from a center channel of the display panel 110. For example, the fifth partition 1731 may separate a channel or a sound generated by the first vibration device 500HL and the second vibration device 500HR disposed at the upper portion of the display panel 110 from a channel or a sound generated by the third vibration device W1, the fourth vibration device W2, and the fifth vibration device 500C disposed at the lower portion of the display panel 110. The sixth partition 1732 may be disposed at the lower portion of the display panel 110 and may be separated from a driver for driving the display panel 110. For example, the sixth partition 1732 may be disposed at the lower portion of the third vibration device W1, the fourth vibration device W2, and the fifth vibration device 500C. For example, the sixth spacer 1732 may separate the third vibration device W1, the fourth vibration device W2, and the fifth vibration device 500C from a driver for driving the display panel 110. The fifth spacer 1731 may be disposed between the first region (1) to the third region (3) and the fourth region (4) to the sixth region (6). The sixth spacer 1732 may be disposed at the lower portion of the fourth region (4) to the sixth region (6).

[0317] The first to sixth spacers 1711 to 1732 may be disposed at the support member 300. For example, the first to sixth spacers 1711 to 1732 may be disposed on the upper surface of the support member 300. For example, the first to sixth spacers 1711 to 1732 may be disposed between the display panel 110 and the support member 300. For example, the first to sixth spacers 1711 to 1732 may be disposed between the rear surface of the display panel 110 and the upper surface of the support member 300.

[0318] Reference Figure 6B, the display device may include first to fifth spacers 1711 to 1731 and a seventh spacer 1750 disposed between the support member 300 and the display panel 110. For example, the seventh spacer 1750 may be disposed at the periphery of the support member 300. For example, the seventh spacer 1750 may be disposed at the periphery of the upper surface of the support member 300. The seventh spacer 1750 may be the entire area of ​​the four sides of the outer side of the upper surface of the support member 300. As another embodiment of the present disclosure, the seventh spacer 1750 may be disposed at the periphery of the rear surface of the display device 100 (e.g., the display panel 110). For example, the seventh spacer 1750 may surround the periphery of the display device 100 (e.g., the display panel 110). The seventh spacer 1750 may be the entire area of ​​the four sides of the outer side of the rear surface of the display panel 110. The seventh spacer 1750 may be the entire area of ​​the rear surface of the display panel 110 or the entire area of ​​the support member 300. For example, the seventh spacer 1750 may be disposed to surround the first to fifth vibration devices 500HL to 500C. For example, the seventh spacer 1750 may be disposed along an area between the rear periphery of the display panel 110 and the front periphery of the support member 300 to surround the vibration device. The seventh spacer 1750 may be referred to as an edge spacer, a sound blocking member, an edge housing, or an edge baffle, but the embodiments of the present disclosure are not limited thereto. The seventh spacer 1750 may be disposed along the shape of the display device 100 to prevent a wave phenomenon of the display device 100. The wave phenomenon may be a phenomenon in which the shape of the spacer causes the screen of the display device to bulge when the thickness of the substrate constituting the display device becomes thinner. In addition, it may also be a problem in which some areas of the display panel are identified as uneven due to the unevenness of the display device or the unevenness of the support member. For example, when the seventh spacer 1750 is Figures 1 to 5E When the adhesive member for attaching the display panel 110 and the supporting member 330 described in Figures 1 to 5E , and the seventh spacer 1750 may serve as an adhesive member. However, the embodiments of the present disclosure are not limited thereto, and an adhesive member for attaching the display panel 110 and the support member 300 may be provided at the support member 300 or at the rear surface of the display panel 110. For example, the seventh spacer 1750 may be provided adjacent to or in contact with the connecting member 550, and may be surrounded by the connecting member 550. As another embodiment of the present disclosure, the seventh spacer 1750 and the connecting member 550 may be provided as one body (or a single body).

[0319] Therefore, since the display device according to one embodiment of the present disclosure further includes the seventh partition 1750, the peak phenomenon or the sedimentation phenomenon can be reduced, and the flatness of the sound characteristics can be improved. For example, the peak phenomenon can be a phenomenon in which the sound pressure level suddenly rises (bounce) at a specific frequency, and the sedimentation phenomenon can be a phenomenon in which a low sound pressure level is generated because a specific frequency is not generated. For example, the flatness of the sound characteristics can be the deviation amplitude between the highest sound pressure level and the lowest sound pressure level.

[0320] The first to seventh spacers 1711 to 1750 may include one or more of a double-sided tape, a double-sided foam tape, a double-sided pad, a double-sided foam pad, a single-sided tape, a single-sided foam tape, a single-sided pad, a single-sided foam pad, an adhesive, and a bonding agent, but the embodiments of the present disclosure are not limited thereto. When the first to seventh spacers 1711 to 1750 are configured with a double-sided tape or a double-sided foam pad, the adhesive force can be enhanced in the process of attaching the rear surface of the display panel 110 to the upper surface of the support member 300. For example, at least one or more of the first to seventh spacers 1711 to 1750 may include a material with elasticity that can achieve a certain degree of compression. For example, the first to seventh spacers 1711 to 1750 may include polyurethane, polyolefin, or polyethylene, but the embodiments of the present disclosure are not limited thereto.

[0321] According to some embodiments of the present disclosure, at least one first vibration device 500HL may be disposed at a first area (1) of the rear surface of the display panel. At least one second vibration device 500HR may be disposed at a second area (2) of the rear surface of the display panel. For example, the first vibration device 500HL may be a left upper channel or a left high channel. For example, the second vibration device 500HR may be a right upper channel or a right high channel.

[0322] According to some embodiments of the present disclosure, at least one third vibration device W1 may be disposed at a fourth region (4) of the rear surface of the display panel. At least one fourth vibration device W2 may be disposed at a fifth region (5) of the rear surface of the display panel. At least one fifth vibration device 500C may be disposed at a sixth region (6) of the rear surface of the display panel. For example, the third vibration device W1 may be a left channel, the fourth vibration device W2 may be a right channel, and the fifth vibration device 500C may be a center channel.

[0323] For example, the first vibration device 500HL and the second vibration device 500HR may be an upper channel or a high channel. The third to fifth vibration devices W1, W2, and 500HC may be main channels. For example, the first vibration device 500HL and the second vibration device 500HR may be vibration devices that output a full range of sounds. The third to fifth vibration devices W1, W2, and 500HC may be vibration devices that output a full range of sounds. For example, a full range of vocal cords may be about 300Hz or greater, but embodiments of the present disclosure are not limited thereto. For example, when the third vibration device W1 and the fourth vibration device W2 are provided, left and right sounds may be reproduced. In addition, in a display device according to an embodiment of the present disclosure, since the first vibration device 500HL and the second vibration device 500HR are also provided, an upper channel (or a high channel or an upper sound) may be reproduced, thereby realizing the real sound of the upper channel. For example, in the display device according to one embodiment of the present disclosure, since the first vibration device 500HL and the second vibration device 500HR are also provided, there may be no position difference between the picture and the sound image, and therefore, a sound image based on the picture can be realized, thereby realizing a real sound based on the position. In addition, since the fifth vibration device 500C is also configured with a center channel in addition to the left sound and the right sound, a display device for outputting multi-channel sound can be realized.

[0324] According to some embodiments of the present disclosure, the vibration device may not be configured at the third area (3). Therefore, the vibration of the first vibration device 500HL and the second vibration device 500HR can be attenuated and absorbed in the third area (3) of the display panel 110, and therefore, the sound transmission from the first area (1) to the second area (2) can be prevented or reduced, and the sound transmission from the second area (2) to the first area (1) can be prevented or reduced. Therefore, the degradation of the sound quality caused by the interference of the sound generated in the first area (1) and the second area (2) can be reduced, and the sound characteristics of the middle and high pitch vocal cords can be better enhanced. For example, the middle pitch vocal cords can be about 200 Hz to about 3 kHz, the high pitch vocal cords can be 3 kHz or more, and the low pitch vocal cords can be 200 Hz or less. However, the range of the vocal cords is not limited thereto.

[0325] Therefore, the display device according to one embodiment of the present disclosure may include five vibration devices, and may be configured with a plurality of vibration devices including an upper channel or a high channel and a main channel, thereby providing five channels. In addition, the five vibration devices may be independently provided with a sound signal and driven by the sound signal, so that each of the five vibration devices can reproduce an independent channel.

[0326] For example, since the third vibration device W1 and the fourth vibration device W2 are configured as woofer-integrated vibration devices, 3.1.2 channels or 3.2.2 channels can be implemented. In addition, since the third vibration device W1 and the fourth vibration device W2 are configured as woofer-integrated vibration devices, there is no need to separately provide a woofer for reproducing the sound of the low-pitched vocal range. Fig.11A and Fig. 11B A woofer speaker integrated with a vibration device is described.

[0327] According to some embodiments of the present disclosure, for the left-right symmetry of the sound, the third vibration device W1 and the fourth vibration device W2 may be configured as the same vibration device. For example, one or more of the first vibration device 500HL and the second vibration device 500HR may be configured as a vibration device different from one or more of the third vibration device W1 and the fourth vibration device W2. For example, the first vibration device 500HL and the second vibration device 500HR may be configured as coil-type vibration devices. The coil-type vibration device may be the same as that described above with reference to Figures 1 to 5E The vibration device described. For example, the third vibration device W1 and the fourth vibration device W2 can be configured as a woofer integrated vibration device or a vibration device including a woofer. For example, one or more of the first vibration device 500HL and the second vibration device 500HR can be configured as a vibration device different from one or more of the third vibration device W1, the fourth vibration device W2 and the fifth vibration device 500C. The fifth vibration device 500C can be configured as a vibration device that is the same as the first vibration device 500HL and the second vibration device 500HR. For example, the fifth vibration device 500C can be configured as a coil-type vibration device. Therefore, a display device for realizing 3.2.2 channels can be provided. In addition, the first vibration device 500HL, the second vibration device 500HR and the fifth vibration device 500C can be configured as a vibration device that is cheaper than the third vibration device W1 and the fourth vibration device W2. Therefore, the channels of the third vibration device W1 and the fourth vibration device W2 as the main channels can be enhanced, so that the sound can be enhanced, and the cost of the vibration device can be reduced.

[0328] The inventors have recognized that although the partition is configured to separate the upper channel or sound from the lower channel or sound, it is difficult to output the sound of the low-pitched vocal band. Therefore, the inventors have conducted various experiments to realize the sound of the low-pitched vocal band, and have realized multi-channel sound including the low-pitched vocal band based on the various experiments.

[0329] Reference Fig. 6A, the size of one or more of the first partition 1711 and the second partition 1712 may be configured to be different from the size of one or more of the third partition 1721 and the fourth partition 1722. For example, the length of one or more of the first partition 1711 and the second partition 1712 may be configured to be different from the length of one or more of the third partition 1721 and the fourth partition 1722. For example, the length a1 of the first partition 1711 may be configured to be different from the length a4 of the third partition 1721. For example, the length a1 of the first partition 1711 may be configured to be smaller than the length a4 of the third partition 1721. Therefore, the first vibration device 500HL and the second vibration device 500HR can output a vocal cord of 300 Hz or higher, and the third vibration device W1, the fourth vibration device W2, and the fifth vibration device 500C can output a full range of vocal cords.

[0341] Reference Fig. 6A and Figure 6B , the size of the first area (1) and the second area (2) may be the same as or different from the size of the third area (3). When the size of the third area (3) is larger than the size of the first area (1) and the second area (2), the sound of the low-pitched vocal range may be better enhanced. For example, the size of the fourth area (4), the size of the fifth area (5), and the size of the sixth area (6) may be the same.

For example, stereo and vivid sound can be provided on the side or part of the upward, downward, left and right sides based on the position of an object or person in the displayed picture. According to one embodiment of the present disclosure, compared with a sound bar, a first vibration device 500HL and a second vibration device 500HR as an upper channel or a high channel can generate sound at a high position, thereby providing a vibration device for implementing sound without the need for an additional algorithm.

[0344] Reference Fig. 7A and Figure 7B According to another embodiment of the present disclosure, a display device may include a display apparatus 100, the display apparatus 100 includes a display panel 110, the display panel 110 includes a first area (1), a second area (2), a third area (3), a fourth area (4), a fifth area (5), and a sixth area (6). One or more vibration devices may be provided at one or more of the first area (1) to the sixth area (6).

[0345] According to some embodiments of the present disclosure, at least one first vibration device 500HL may be disposed at a first area (1) of the rear surface of the display panel 110, and at least one second vibration device 500HR may be disposed at a second area (2) of the rear surface of the display panel 110. For example, the first vibration device 500HL may be a left upper channel or a left high channel. For example, the second vibration device 500HR may be a right upper channel or a right high channel.

[0346] At least one third vibration device 500L may be disposed at a fourth area (4) of the rear surface of the display panel 110, and at least one fourth vibration device 500R may be disposed at a fifth area (5) of the rear surface of the display panel 110. At least one fifth vibration device 500C may be disposed at a sixth area (6) of the rear surface of the display panel 110. For example, the third vibration device 500L may be a left channel, the fourth vibration device 500R may be a right channel, and the fifth vibration device 500C may be a center channel.

[0347] For example, the first vibration device 500HL and the second vibration device 500HR may be upper channels or high channels, and the third vibration device 500L, the fourth vibration device 500R, and the fifth vibration device 500C may be main channels. The first vibration device 500HL and the second vibration device 500HR may be vibration devices that output full-range sounds. The third vibration device 500L, the fourth vibration device 500R, and the fifth vibration device 500C may be vibration devices that output full-range sounds. For example, the full-range vocal cord may be about 300Hz or higher, but the embodiments of the present disclosure are not limited thereto. For example, in the case where the third vibration device 500L and the fourth vibration device 500R are provided, left and right sounds may be reproduced. In addition, in a display device according to an embodiment of the present disclosure, since the first vibration device 500HL and the second vibration device 500HR are also provided, the upper channel or the high channel may be reproduced, thereby realizing the real sound of the upper channel. For example, in the display device according to one embodiment of the present disclosure, since the first vibration device 500HL and the second vibration device 500HR are also provided, there may be no position difference between the picture and the sound image, and therefore, a sound image based on the picture can be realized, thereby realizing a real sound based on the position. In addition, since the fifth vibration device 500C is also configured with a center channel in addition to the left sound and the right sound, a display device for outputting multi-channel sound can be realized.

[0348] According to some embodiments of the present disclosure, the third region (3) may not be configured with a vibration device. Therefore, the vibration of the first vibration device 500HL and the second vibration device 500HR can be attenuated and absorbed in the third region (3) of the display panel 110, and thus, the sound transmission from the first region (1) to the second region (2) can be prevented or reduced, and the sound transmission from the second region (2) to the first region (1) can be prevented or reduced. Therefore, the degradation of the sound quality caused by the interference of the sound generated in the first region (1) and the second region (2) can be reduced, and the sound characteristics of the middle-pitched vocal cords and the high-pitched vocal cords can be better enhanced.

[0349] Therefore, a display device according to an embodiment of the present disclosure may include five vibration devices, and may be configured with a plurality of vibration devices including an upper channel or a high channel and a main channel, thereby providing a display device including five channels. In addition, the five vibration devices may be independently provided with sound signals and driven by the sound signals, and therefore, each of the five vibration devices may reproduce an independent channel.

[0350] According to some embodiments of the present disclosure, for the left-right symmetry of the sound, the third vibration device 500L and the fourth vibration device 500R may be configured as the same vibration device. For example, the third vibration device 500L and the fourth vibration device 500R may be configured as coil-type vibration devices. The coil-type vibration device may be the same as the one described above. Figures 1 to 5E The vibration device described. For example, one or more of the first vibration device 500HL and the second vibration device 500HR can be configured as the same vibration device as one or more of the third vibration device 500L, the fourth vibration device 500R, and the fifth vibration device 500C. The fifth vibration device 500C can be configured as the same vibration device as the first vibration device 500HL and the second vibration device 500HR. For example, the fifth vibration device 500C can be configured as a coil-type vibration device. Therefore, a display device for realizing 3.2.2 channels can be provided.

[0351] Reference Fig. 7A and Figure 7B , the size of one or more of the first partition 1711 and the second partition 1712 may be configured to be different from the size of one or more of the third partition 1721 and the fourth partition 1722. The size of one or more of the fifth partition 1731 and the sixth partition 1732 may be configured to be different from the size of one or more of the first partition 1711 and the second partition 1712. For example, the length of one or more of the first partition 1711 and the second partition 1712 may be configured to be different from the length of one or more of the third partition 1721 and the fourth partition 1722. For example, the length of one or more of the fifth partition 1731 and the sixth partition 1732 may be configured to be different from the length of one or more of the first partition 1711 and the second partition 1712. Therefore, the first vibration device 500HL and the second vibration device 500HR can output a vocal cord of 300 Hz or higher, and the third vibration device 500L, the fourth vibration device 500R, and the fifth vibration device 500C can output a full range vocal cord. The description of the separator and the first region (1) to the sixth region (6) can be referred to above. Fig. 6A and Figure 6B The descriptions given are the same, so duplicate descriptions are omitted.

[0352] Therefore, according to one embodiment of the present disclosure, the size of the partition near the vibration device may be variously configured, thereby providing a display apparatus including a vibration device for outputting a sound band of 180 Hz or higher and / or a full-range sound band.

For example, each of the first vibration device 600HL and the second vibration device 600HR may have a square shape or a rectangular shape. For example, the first vibration device 600HL may be a left upper channel or a left high channel. For example, the second vibration device 600HR may be a right upper channel or a right high channel.

For example, the third vibration device W1 may be a left channel, the fourth vibration device W2 may be a right channel, and the fifth vibration device 500C may be a center channel.

[0357] For example, the first vibration device 600HL and the second vibration device 600HR may be upper channels or high channels, and the third vibration device W1, the fourth vibration device W2, and the fifth vibration device 500C may be main channels. The first vibration device 600HL and the second vibration device 600HR may be vibration devices that output full-range sounds. The third vibration device W1, the fourth vibration device W2, and the fifth vibration device 500C may be vibration devices that output full-range sounds. For example, the full-range vocal cord may be about 300Hz or higher, but the embodiments of the present disclosure are not limited thereto. For example, in the case where the third vibration device W1 and the fourth vibration device W2 are provided, left and right sounds may be reproduced. In addition, in a display device according to an embodiment of the present disclosure, since the first vibration device 600HL and the second vibration device 600HR are also provided, the upper channel or the high channel may be reproduced, thereby realizing the real sound of the upper channel. For example, in the display device according to one embodiment of the present disclosure, since the first vibration device 600HL and the second vibration device 600HR are also provided, there may be no position difference between the picture and the sound image, and therefore, a sound image based on the picture can be realized, thereby realizing a real sound based on the position. In addition, since the fifth vibration device 500C is also configured with a center channel in addition to the left sound and the right sound, a display device for outputting multi-channel sound can be realized.

[0358] According to some embodiments of the present disclosure, the third region (3) may not be configured with a vibration device. Therefore, the vibration of the first vibration device 600HL and the second vibration device 600HR can be attenuated and absorbed in the third region (3) of the display panel 110, and thus, the sound transmission from the first region (1) to the second region (2) can be prevented or reduced, and the sound transmission from the second region (2) to the first region (1) can be prevented or reduced. Therefore, the degradation of the sound quality caused by the interference of the sound generated in the first region (1) and the second region (2) can be reduced, and the sound characteristics of the middle-pitched vocal cords and the high-pitched vocal cords can be better enhanced.

[0359] Therefore, a display device according to an embodiment of the present disclosure may include five vibration devices, and may be configured with a plurality of vibration devices including an upper channel or a high channel and a main channel, thereby providing a display device including five channels. In addition, the five vibration devices may be independently provided with sound signals and driven by the sound signals, and therefore, each of the five vibration devices may reproduce an independent channel.

[0360] For example, since the third vibration device W1 and the fourth vibration device W2 are configured as woofer integrated vibration devices, 3.1.2 channels or 3.2.2 channels can be implemented. In addition, since the third vibration device W1 and the fourth vibration device W2 are configured as woofer integrated vibration devices, there is no need to separately set a woofer for reproducing the sound of the low-pitched vocal range.

[0361] According to some embodiments of the present disclosure, for the left-right symmetry of the sound, the third vibration device W1 and the fourth vibration device W2 may be configured as the same vibration device. One or more of the first vibration device 600HL and the second vibration device 600HR may be configured as a vibration device different from one or more of the third vibration device W1 and the fourth vibration device W2. For example, one or more of the first vibration device 600HL and the second vibration device 600HR may be configured as a thin film type vibration device. Figures 12 to 17 A film-type vibration device is described. For example, one or more of the third vibration device W1 and the fourth vibration device W2 may be configured as a woofer integrated vibration device. For example, one or more of the first vibration device 600HL and the second vibration device 600HR may be configured as a vibration device different from one or more of the third vibration device W1, the fourth vibration device W2, and the fifth vibration device 500C. For example, the fifth vibration device 500C may be configured as a coil-type vibration device. For example, the first vibration device 600HL to the fifth vibration device 500C may be configured as two or more different vibration devices. Therefore, a display device for realizing 3.2.2 channels can be realized.

[0362] Reference Fig. 8A , the size of one or more of the first partition 1711 and the second partition 1712 may be configured to be different from the size of one or more of the third partition 1721 and the fourth partition 1722.

For example, the length a1 of the first partition 1711 may be configured to be greater than the length a4 of the third partition 1721. Therefore, the first vibration device 600HL and the second vibration device 600HR can output a vocal cord of 300Hz or higher, and the third vibration device W1, the fourth vibration device W2, and the fifth vibration device 500C can output a full range of vocal cords.

[0374] Reference Fig. 8A and Figure 8B , the size of the first area (1) and the second area (2) may be the same as or different from the size of the third area (3). When the size of the third area (3) is larger than the size of the first area (1) and the second area (2), the sound of the low-pitched vocal range may be better enhanced. For example, the size of the fourth area (4), the size of the fifth area (5), and the size of the sixth area (6) may be the same.

[0375] Therefore, according to one embodiment of the present disclosure, the size of the partition near the vibration device can be adjusted differently, thereby providing a display device including a vibration device for outputting a vocal cord of 180 Hz or higher and / or a full-range vocal cord. For example, the size of the partition of the first vibration device 600HL and the second vibration device 600HR, which are thin-film vibration devices, can be configured to be larger than the size of the partition of the other vibration devices, and thus, a vocal cord of 180 Hz or higher and / or a full-range vocal cord can be output.

[0376] Fig. 9A and Fig. 9B A display device including a vibration apparatus according to another embodiment of the present disclosure is shown.

[0377] Reference Fig. 9A and Fig. 9BThe display device may include a display apparatus 100, the display apparatus 100 includes a display panel 110, the display panel 110 includes a first area (1), a second area (2), a third area (3), a fourth area (4), a fifth area (5), and a sixth area (6). One or more vibration devices may be provided at one or more of the first area (1) to the sixth area (6).

[0378] According to some embodiments of the present disclosure, at least one first vibration device 600HL may be disposed at a first area (1) of the rear surface of the display panel 110, and at least one second vibration device 600HR may be disposed at a second area (2) of the rear surface of the display panel 110. For example, the first vibration device 600HL may be a left upper channel or a left high channel. For example, the second vibration device 600HR may be a right upper channel or a right high channel.

[0379] At least one third vibration device 500L may be disposed at a fourth area (4) of the rear surface of the display panel 110, and at least one fourth vibration device 500R may be disposed at a fifth area (5) of the rear surface of the display panel 110. At least one fifth vibration device 500C may be disposed at a sixth area (6) of the rear surface of the display panel 110. For example, the third vibration device 500L may be a left channel, the fourth vibration device 500R may be a right channel, and the fifth vibration device 500C may be a center channel.

[0380] For example, the first vibration device 600HL and the second vibration device 600HR may be upper channels or high channels, and the third vibration device 500L, the fourth vibration device 500R, and the fifth vibration device 500C may be main channels. The first vibration device 600HL and the second vibration device 600HR may be vibration devices that output full-range sounds. The third vibration device 500L, the fourth vibration device 500R, and the fifth vibration device 500C may be vibration devices that output full-range sounds. For example, the full-range vocal cord may be about 300Hz or higher, but the embodiments of the present disclosure are not limited thereto. For example, when the third vibration device 500L and the fourth vibration device 500R are provided, left and right sounds may be reproduced. In addition, in a display device according to an embodiment of the present disclosure, since the first vibration device 600HL and the second vibration device 600HR are also provided, the upper channel or the high channel may be reproduced, thereby realizing the real sound of the upper channel. For example, in the display device according to one embodiment of the present disclosure, since the first vibration device 600HL and the second vibration device 600HR are also provided, there may be no position difference between the picture and the sound image, and therefore, a sound image based on the picture can be realized, thereby realizing a real sound based on the position. In addition, since the fifth vibration device 500C is also configured with a center channel in addition to the left sound and the right sound, a display device for outputting multi-channel sound can be realized.

[0381] According to some embodiments of the present disclosure, the third region (3) may not be configured with a vibration device. Therefore, the vibration of the first vibration device 600HL and the second vibration device 600HR can be attenuated and absorbed in the third region (3) of the display panel 110, and thus, the sound transmission from the first region (1) to the second region (2) can be prevented or reduced, and the sound transmission from the second region (2) to the first region (1) can be prevented or reduced. Therefore, the degradation of the sound quality caused by the interference of the sound generated in the first region (1) and the second region (2) can be reduced, and the sound characteristics of the middle-pitched vocal cords and the high-pitched vocal cords can also be enhanced.

[0382] Therefore, a display device according to an embodiment of the present disclosure may include five vibration devices, and may be configured with a plurality of vibration devices including an upper channel or a high channel and a main channel, thereby providing a display device including five channels. In addition, the five vibration devices may be independently provided with sound signals and driven by the sound signals, and therefore, each of the five vibration devices may reproduce an independent channel.

[0383] According to some embodiments of the present disclosure, for the left-right symmetry of the sound, the third vibration device 500L and the fourth vibration device 500R may be configured as the same vibration device. For example, the third vibration device 500L and the fourth vibration device 500R may be configured as coil-type vibration devices. The coil-type vibration device may be the same as the one described above. Figures 1 to 5E The vibration device described. For example, one or more of the first vibration device 600HL and the second vibration device 600HR may be configured as the same vibration device as one or more of the third vibration device 500L, the fourth vibration device 500R, and the fifth vibration device 500C. The first vibration device 600HL and the second vibration device 600HR may be configured as a film-type vibration device. The fifth vibration device 500C may be configured as the same vibration device as the first vibration device 600HL and the second vibration device 600HR. For example, the fifth vibration device 500C may be configured as a coil-type vibration device. For example, the first vibration device 600HL to the fifth vibration device 500C may be configured as two or more different vibration devices. Therefore, a display device for realizing 3.2.2 channels can be realized.

[0384] Reference Fig. 9A and Fig. 9B , the size of one or more of the first partition 1711 and the second partition 1712 may be configured to be different from the size of one or more of the third partition 1721 and the fourth partition 1722. The size of one or more of the fifth partition 1731 and the sixth partition 1732 may be configured to be different from the size of one or more of the first partition 1711 and the second partition 1712. For example, the length of one or more of the first partition 1711 and the second partition 1712 may be configured to be different from the length of one or more of the third partition 1721 and the fourth partition 1722. For example, the length of one or more of the fifth partition 1731 and the sixth partition 1732 may be configured to be different from the length of one or more of the first partition 1711 and the second partition 1712. Therefore, the first vibration device 600HL and the second vibration device 600HR can output a vocal cord of 300Hz or higher, and the third vibration device 500L, the fourth vibration device 500R, and the fifth vibration device 500C can output a full range of vocal cords. The description of the separator and the first region (1) to the sixth region (6) can be referred to above. Fig. 8A and Figure 8B The descriptions given are the same, so duplicate descriptions are omitted.

[0385] Therefore, according to one embodiment of the present disclosure, the size of the partition near the vibration device may be adjusted differently, thereby providing a display apparatus including a vibration device for outputting a sound band of 180 Hz or higher and / or a full-range sound band.

[0386] FIG. 10A to FIG. 10F A display device including a vibration apparatus according to another embodiment of the present disclosure is shown.

[0387] The following will refer to, for example Fig. 6A Display device to describe FIG. 10A to FIG. 10D ,and FIG. 6B to FIG. 7B The display device of can also be applied to this in the same way. Fig. 8A Display device to describe Fig.10E and Fig.10F ,and FIG. 8B to FIG. 9B The display device can also be applied here in the same way.

[0388] The sound waves generated when the display device 100 (e.g., the display panel 110) is vibrated by the vibration device 500 can be radially expanded from the center of the vibration device and can propagate. The sound waves can be called forward waves. The forward waves can be reflected on one side of the partition to generate reflected waves, and the reflected waves can propagate in the opposite direction of the forward waves. The reflected waves overlap and interfere with the forward waves and do not propagate, thereby generating standing waves that stop at a certain position. The sound pressure is reduced by the standing waves, and therefore, the sound output characteristics are deteriorated.

[0389] When a partition is provided at the display device 100, the peak phenomenon or the sedimentation phenomenon caused by the standing wave cannot be controlled. The peak phenomenon may be a phenomenon in which the sound pressure level rises suddenly in a specific frequency, and the sedimentation phenomenon may be a phenomenon in which the generation of a specific frequency is suppressed to produce a low sound pressure. The sound output characteristics of the vibration device 500 may be reduced due to the peak phenomenon or the sedimentation phenomenon. The structure for controlling the peak phenomenon or the sedimentation phenomenon is not simply implemented, but has been implemented through various experiments. Therefore, a pad portion may be provided at the partition to reduce the peak phenomenon or the sedimentation phenomenon caused by the standing wave appearing in the longitudinal direction of the vibration device. The sound pressure reduction phenomenon caused by the standing wave generated by the interference between the reflected wave and the forward wave can be reduced by the pad portion. However, the phenomenon that the shape of the partition protrudes to the screen of the display device 100 (e.g., the display panel 110) due to the shape of the pad portion may occur, and the problem of identifying the uneven display panel due to the uneven display device or display panel or the uneven support member may occur. This phenomenon may be an uneven phenomenon or a fluctuation phenomenon (hereinafter referred to as a fluctuation phenomenon) of the display device 100 (e.g., the display panel 110) or the support member 300, but the embodiments of the present disclosure are not limited thereto. Therefore, the partition should be implemented to prevent the fluctuation phenomenon and to easily control the peak phenomenon or the sedimentation phenomenon caused by the standing wave. Therefore, the inventors conducted various experiments on the shape of the partition. Through various experiments, the inventors have realized that the partition should be set based on the shape of the display device 100 (e.g., the display panel 110). For example, the partition may have a quadrilateral shape but is not limited thereto, and the shape of the partition may be changed based on the shape or perimeter shape of the display panel 110. When the display device 100 (e.g., the display panel 110) is a curved display panel device or a curved display panel device having an arc shape, etc., the partition may have a curved surface shape or an arc shape. Therefore, because the partition is set along the shape or perimeter shape of the display device 100 (e.g., the display panel 110), the attraction of the display device 100 (e.g., the display panel 110) is reduced during the process of attaching the support member 300 to the display device 100 (e.g., the display panel 110), and thus the fluctuation phenomenon can be prevented.

[0390] The shape of the pad portion may be configured to prevent a fluctuation phenomenon from occurring when the display device 100 is pulled in the process of being attached to the support member due to the pad portion at the support member. Alternatively, the shape of the pad portion may be configured to prevent a fluctuation phenomenon from occurring when the display device 100 is pulled in the process of being attached to the support member due to the pad portion at the display panel. For example, the pad portion should be implemented to easily control a peak phenomenon or a settling phenomenon caused by a standing wave of a vibration device, and to prevent a fluctuation phenomenon. In the following embodiments, an example in which a spacer is disposed at a support member will be described, and the embodiments of the present disclosure are not limited thereto, and the spacer may be disposed at the rear surface of the display panel. In order to illustrate the vibration device and the spacer, an example in which a spacer is disposed at a support member will be described. For example, when a spacer is disposed at a support member, the adverse effect on the image quality of the display panel caused by a spacer disposed at the display panel can be reduced.

[0391] Reference FIG. 10A to FIG. 10F , the standing waves that cause the sound pressure level to decrease may appear more at points where the amplitudes of the forward wave and the reflected wave are larger. Therefore, the pad portion can be set at the position where the sound wave transmitted from the vibration device is the largest. For example, the pad portion can be set at one or more sides of the four sides of the partition to which the strongest sound wave is transmitted, and can be implemented toward the vibration device.

[0392] Reference Fig. 10A and Fig. 10B, one or more pad sections may be disposed at one or more sides of the first separator 1711.

[0420] The lower frame 1610a may support the rear surface of the magnet 1620. For example, the lower frame 1610a may support the magnet 1620. The magnet 1620 may share the first vibration generating part 1801 and the second vibration generating part 1802. For example, the bobbin 1650a of the first vibration generating part 1801 and the coil 1660a near the bobbin 1650a may be arranged near the magnet 1620. For example, the second bobbin 1650b of the second vibration generating part 1802 and the second coil 1660b near the second bobbin 1650b may be arranged near the magnet 1620. For example, the lower frame 1610a and the plate 1611 may be respectively arranged at the lower and upper parts of the magnet 1620, and the magnetic flux density generated by the magnet 1620, the coil 1660a and the second coil 1660b may be increased, thereby enhancing the vibration characteristics. The lower frame 1610a may be a yoke, but embodiments of the present disclosure are not limited thereto.

[0421] The side frame 1610b may be connected or coupled to the lower frame 1610a, and may include at least one hole 217 to output sound or vibration. For example, the hole 217 may be a vent. For example, the hole 217 may output the sound of a low-pitched vocal band generated by the vibration plate 214b of the second vibration generating portion 1802 in the air gap inside the vibration device 1800 to the rearward area behind the display panel 110.

[0422] The side frame 1610b may include a conductive material and may control the magnetic flux generated by the magnet 1620. For example, the side frame 1610b may surround the magnet 1620 and be spaced apart therefrom, thereby allowing the magnetic flux generated by the magnet 1620 to be concentrated inside the second bobbin 1650b, thereby preventing leakage magnetic flux. The side frame 1610b may be a yoke, but the embodiments of the present disclosure are not limited thereto. The hole 217 may be provided in the side frame 1610b, and may further be provided in the lower frame 1610a, and may be provided in an area connected to the side frame 1610b and the lower frame 1610a. The side frame 1610b may be connected to the back cover by a connecting member 1710 such as a nut or a bolt, or may be provided between the display panels.

[0423] The first vibration generating part 1801 may include a magnet 1620 disposed on the frame, a bobbin 1650a near the magnet 1620, and a coil 1660a and a damper 1670a near the bobbin 1650a. For example, the description thereof is the same as that described above with reference to Figures 2 to 5E The descriptions given are similar, and thus, duplicate descriptions thereof may be omitted or briefly given.

[0424] The magnet 1620 may be disposed on the lower frame 1610a. For example, the magnet 1620 may be disposed between the plate 1611 and the lower frame 1610a. The lower frame 1610a and the plate 1611 may control the magnetic flux generated by the magnet 1620. For example, the magnet 1620 may be surrounded by the lower frame 1610a and the plate 1611, and thus, the magnetic flux generated by the magnet 1620 may be concentrated inside the bobbin 1650a and may be controlled.

[0425] The bobbin 1650a may be attached to the rear surface of the bobbin ring 1652a. For example, when a sound generating current (or a vibration generating current) is applied to the coil 1660a wound on the outer peripheral surface of the bobbin 1650a to generate a magnetic field in the first vibration generating unit 1801, a display device (e.g., a display panel) may vibrate based on the magnetic field through the bobbin ring 1652a. The bobbin ring 1652a may be located between the bobbin 1650a and the display panel, and the vibration of the bobbin 1650a may be transmitted to the display panel. The first vibration generating unit 1801 may output the sound of the middle and high pitch vocal cords.

[0426] The second vibration generating part 1802 may include a magnet 1620 disposed on the frame, a plate 1611 on the magnet 1620 , a second bobbin 1650 b near the magnet 1620 , and a second coil 1660 b and a second damper 1670 b near the second bobbin 1650 b .

[0427] The vibration plate 214b may be disposed on the second bobbin 1650b. For example, the vibration plate 214b may be spaced apart from the rear surface of the display panel, and heat generated in the second bobbin 1650b may be prevented from being transferred to the display panel.

[0428] When a sound generating current (or a vibration generating current) is applied to the second coil 1660b wound on the outer peripheral surface of the second bobbin 1650b to generate a magnetic field in the second vibration generating part 1802, the second bobbin 1650b can vibrate the air layer or air gap of the peripheral portion of the vibration plate through the vibration plate 214b based on the magnetic field to output sound. For example, the front surface of the second bobbin 1650b can contact the vibration plate 214b, and the vibration plate 214b can be vibrated based on the state of whether the current is applied thereto. The second vibration generating part 1802 can output sound to the forward area and the rearward area relative to the vibration plate 214b. For example, the second vibration generating part 1802 can output the sound of the low-pitched vocal cord. For example, the sound generated by the vibration plate 214b of the second vibration generating part 1802 may include a first low-pitched sound propagating to the upper part of the vibration plate 214b and a second low-pitched sound propagating to the lower part of the vibration plate 214b. For example, the second vibration generating part 1802 may be a woofer, but the embodiments of the present disclosure are not limited thereto.

[0429] The magnet 1620 may be disposed on the lower frame 1610a. The plate 1611 may be spaced apart from the vibration plate 214b. The second bobbin 1650b may be disposed on the rear surface of the vibration plate 214b. For example, the second bobbin 1650b may surround the magnet 1620 and the plate 1611.

[0430] The second damper 1670b may be disposed between the first vibration generating part 1801 and the second vibration generating part 1802. For example, the second damper 1670b may be disposed between the damper 1670a of the first vibration generating part 1801 and the second bobbin 1650b of the second vibration generating part 1802. For example, the second damper 1670b may be disposed between the vibration plate 214b of the first vibration generating part 1801 and the second vibration generating part 1802. The vibration plate 214b may not be in physical contact with the first vibration generating part 1801. For example, the second damper 1670b may prevent sound interference between the first vibration generating part 1801 and the second vibration generating part 1802. The edge 1670c may be disposed on the vibration plate 214b. When the vibration plate 214b performs vertical movement, the edge 1670c may prevent deformation (e.g., twisting) of the vibration plate 214b, thereby providing a clean sound quality and enhancing the reliability of the vibration device 1800. The second damper 1670 b may be a first suspension, and the edge 1670 c may be a second suspension, but embodiments of the present disclosure are not limited thereto.

[0431] The magnet 1620 of the first vibration generating unit 1801 and the magnet 1620 of the second vibration generating unit 1802 may have magnetic fields in opposite directions. The first vibration generating unit 1801 may vibrate (or directly vibrate) the display panel to output the sound of the high-pitched vocal cords to the front area in front of the display panel, and the second vibration generating unit 1802 may output the sound of the low-pitched vocal cords to the rear area behind the display panel. Therefore, because the first vibration generating unit 1801 and the second vibration generating unit 1802 have magnetic fields in opposite directions, the vibrations of the first vibration generating unit 1801 and the second vibration generating unit 1802 may be independently driven or controlled.

[0432] Therefore, the woofer integrated vibration device may include a woofer disposed near the vibration device. The vibration device may be disposed on the rear surface of the display panel and may produce the sound of the mid-high pitch vocal cords, while the woofer may be spaced apart from the rear surface of the display panel and may perform vertical vibration to produce the sound of the low pitch vocal cords. For example, the vibration device and the woofer may be driven based on different sound signals or voice signals applied thereto. Therefore, the woofer integrated vibration device may enhance the sound of the low pitch vocal cords.

[0433] In order to provide sound in the display device, in the case of implementing a speaker, the speaker can be implemented as a thin film type, and therefore, the thickness of the display device can be configured to be thin. The thin film type vibration device can be manufactured to have a large area, and therefore can be applied to a large area display device. However, the piezoelectric characteristics of the thin film type vibration device may be low, and therefore, due to the low vibration, there may be a problem of difficulty in applying the thin film type vibration device to a large area display device. When the thin film type vibration device is implemented by applying ceramics to enhance the piezoelectric characteristics, there may be problems of poor durability and limited size of the ceramics.

[0434] When a vibration device including a piezoelectric composite containing piezoelectric ceramics is applied to a display device, the piezoelectric composite may vibrate in a lateral direction relative to the width direction (for example, in a lateral direction relative to the width direction of the display device), and therefore, the display device may not be fully vibrated in an upward and downward (or forward and backward) direction, and thus, it may be difficult to apply the vibration device to the display device, and the desired sound may not be output in the forward direction of the display device. In the case where a thin film piezoelectric element is applied to a display device, there may be a problem of lower sound pressure level characteristics compared to a speaker such as an exciter. In the case where a stacked piezoelectric element (including a plurality of films of a thin film piezoelectric element formed by a plurality of layers being stacked) is applied to a display device to improve the sound pressure level, there may be a problem of increased power consumption and a thicker thickness of the display device. In addition, in the case where a vibration device is set on the rear surface of a display panel (for example, a mobile display device), the inventor has recognized that a mono sound is output, but there is a problem of difficulty in outputting multi-channel sound. Therefore, the vibration device can also be set at the periphery of the display panel to achieve multi-channel sound, but it may be difficult to place the exciter in a flexible display device in which the arc portion is set at the display panel. In addition, in the case of setting a speaker including piezoelectric ceramics, there may be a problem that the piezoelectric ceramics are easily broken. According to one embodiment of the present disclosure, a vibration device suitable for realizing multi-channel sound characteristics and a display device including a flexible display device can be set. This will be referred to below Figures 12 to 17 Give a description.

[0435] Fig.12 A vibration device according to another embodiment of the present disclosure is shown.

[0436] Reference Fig.12 , a vibration device 450 according to one embodiment of the present disclosure may include a piezoelectric vibration portion 451 , a first electrode portion E1 , and a second electrode portion E2 .

[0437] The piezoelectric vibration part 451 may include a piezoelectric material (or an electroactive material) having a piezoelectric effect. For example, the piezoelectric material may have a property in which pressure or distortion (or bending) is applied to a crystal structure by an external force, a potential difference is generated due to dielectric polarization caused by a change in the relative positions of positive (+) ions and negative (-) ions, and vibration is generated by an electric field based on a voltage applied thereto. The piezoelectric vibration part 451 may be referred to as a vibration layer, a piezoelectric layer, a piezoelectric material layer, an electroactive layer, a vibration part, a piezoelectric material part, an electroactive part, a piezoelectric structure, an inorganic material layer, or an inorganic material part, but the embodiments of the present disclosure are not limited thereto.

[0438] The piezoelectric vibration portion 451 may be formed of a transparent, translucent, or opaque piezoelectric material (or electroactive material), and may be transparent, translucent, or opaque. The piezoelectric vibration portion 451 may be formed of a ceramic-based material for generating higher vibrations, or may be formed of a piezoelectric ceramic having a perovskite-based crystal structure.

The perovskite crystal structure may be composed of the chemical formula "ABO 3 Here, A may include a divalent metal element, and B may include a tetravalent metal element. For example, in the chemical formula "ABO 3 ", A and B may be cations, and O may be an anion. For example, a perovskite crystal structure may include PbTiO 3 , PbZrO 3 , PbZrTiO 3 , BaTiO 3 and SrTiO 3 At least one or more of , but the embodiments of the present disclosure are not limited thereto.

[0439] The piezoelectric vibration part 451 according to one embodiment of the present disclosure may include a lead zirconate titanate (PZT)-based material including lead (Pb), zirconium (Zr) and titanium (Ti); or may include a lead zirconate niobate nickel (PZNN)-based material including lead (Pb), zirconium (Zr), nickel (Ni) and niobium (Nb), but the embodiments of the present disclosure are not limited thereto. In addition, the piezoelectric vibration part 451 may include CaTiO 3 , BaTiO 3 and SrTiO 3 At least one or more of , but the embodiments of the present disclosure are not limited thereto.

[0440] The piezoelectric vibration part 451 according to one embodiment of the present disclosure may be configured in a circular shape, an elliptical shape, or a polygonal shape, but the embodiments of the present disclosure are not limited thereto.

[0441] The first electrode portion E1 may be disposed at a first surface (or top surface or upper surface or front surface) of the piezoelectric vibration portion 451 and electrically connected to the first surface of the piezoelectric vibration portion 451. For example, the first electrode portion E1 may have a single electrode type disposed at the entire first surface of the piezoelectric vibration portion 451. For example, the first electrode portion may have the same shape as the piezoelectric vibration portion 451, but embodiments of the present disclosure are not limited thereto. The first electrode portion E1 according to an embodiment of the present disclosure may be formed of a transparent conductive material, a semi-transparent conductive material, or an opaque conductive material. For example, examples of transparent conductive materials or semi-transparent conductive materials may include indium tin oxide (ITO) or indium zinc oxide (IZO), but embodiments of the present disclosure are not limited thereto. Examples of opaque conductive materials may include aluminum (Al), copper (Cu), gold (Au), silver (Ag), molybdenum (Mo), and magnesium, or alloys thereof, but embodiments of the present disclosure are not limited thereto.

[0442] The second electrode portion E2 may be disposed at a second surface (or bottom surface or lower surface or rear surface) of the piezoelectric vibration portion 451 opposite to the first surface, and electrically connected to the second surface of the piezoelectric vibration portion 451. For example, the second electrode portion E2 may have a single electrode type disposed at the entire second surface of the piezoelectric vibration portion 451. For example, the second electrode portion E2 may have a larger size than the piezoelectric vibration portion 451, and may have the same shape as the piezoelectric vibration portion 451, but the embodiments of the present disclosure are not limited thereto. The second electrode portion E2 according to one embodiment of the present disclosure may be formed of a transparent conductive material, a semi-transparent conductive material, or an opaque conductive material. For example, the second electrode portion E2 may be formed of the same material as the first electrode portion E1, but the embodiments of the present disclosure are not limited thereto. In another example, the second electrode portion E2 may be formed of a material different from the first electrode portion E1.

[0443] The piezoelectric vibration portion 451 may be polarized (or polarized) by applying a specific voltage to the first electrode portion E1 and the second electrode portion E2 in a specific temperature atmosphere or in a temperature atmosphere that can be changed from high temperature to room temperature. The embodiments of the present disclosure are not limited to these examples. The piezoelectric vibration portion 451 may vibrate by contracting and expanding alternately and / or repeatedly based on the piezoelectric effect (or piezoelectric characteristics) according to a sound signal (or voice signal) applied from the outside to the first electrode portion E1 and the second electrode portion E2.

[0444] The vibration device 450 according to one embodiment of the present disclosure may further include a first protection member and a second protection member.

[0445] The first protective member may be disposed at the first electrode portion E1 and protect the first electrode portion E1.

[0446] The second protective member may be disposed at the second electrode portion E2 and protect the second electrode portion E2. For example, the second protective member may be formed of a plastic material, a fiber material, or a wood material, but the embodiments of the present disclosure are not limited thereto. For example, the first protective member may be formed of the same or different material as the second protective member. Any one of the first protective member and the second protective member may be attached or coupled to the display panel via an adhesive member.

[0447] Fig.13 A vibration device according to another embodiment of the present disclosure is shown.

[0448] Reference Fig.13 According to another embodiment of the present disclosure, the vibration device 450 may be referred to as a flexible sound generator, a flexible actuator, a flexible speaker, a flexible piezoelectric speaker, a thin film actuator, a thin film piezoelectric composite actuator, a thin film speaker, a thin film piezoelectric speaker or a thin film piezoelectric composite speaker, but the embodiments of the present disclosure are not limited thereto.

[0449] The vibration device 450 according to one embodiment of the present disclosure may include a piezoelectric vibration portion 453 , a first electrode portion E1 , and a second electrode portion E2 .

[0450] The piezoelectric vibration portion 453 may include a piezoelectric material, a composite piezoelectric material, or an electroactive material, and the piezoelectric material, the composite piezoelectric material, and the electroactive material may have a piezoelectric effect. The piezoelectric vibration portion 453 may be referred to as a vibration layer, a piezoelectric layer, a piezoelectric material layer, an electroactive layer, a vibration portion, a piezoelectric material portion, an electroactive portion, a piezoelectric structure, a piezoelectric composite layer, a piezoelectric composite, or a piezoelectric ceramic composite, but the embodiments of the present disclosure are not limited thereto. The piezoelectric vibration portion 453 may be formed of a transparent, translucent, or opaque piezoelectric material, and may be transparent, translucent, or opaque.

[0451] The piezoelectric vibration portion 453 according to one embodiment of the present disclosure may include a plurality of first portions 453a and a plurality of second portions 453b. For example, the plurality of first portions 453a and the plurality of second portions 453b may be arranged alternately and repeatedly in the first direction X (or the second direction Y). For example, the first direction X may be the width direction or the first horizontal direction of the piezoelectric vibration portion 453. The second direction Y may be the longitudinal direction or the second horizontal direction of the piezoelectric vibration portion 453. The embodiments of the present disclosure are not limited thereto, and the first direction X may be the longitudinal direction or the second horizontal direction of the piezoelectric vibration portion 453, and the second direction Y may be the width direction or the first horizontal direction of the piezoelectric vibration portion 453.

[0452] Each of the plurality of first portions 453a may be configured as an inorganic material portion. The inorganic material portion may include the above-mentioned piezoelectric material. For example, each of the plurality of first portions 453a may include the same Fig.12 The piezoelectric vibration portion 453 described above is substantially the same piezoelectric material, and therefore, a repeated description thereof may be omitted.

[0453] Each of the plurality of first portions 453a according to an embodiment of the present disclosure may be disposed between the plurality of second portions 453b. For example, the plurality of first portions 453a may have a first width W1 parallel to the first direction X (or the second direction Y) and a length parallel to the second direction Y (or the first direction X). Each of the plurality of second portions 453b may have a second width W2 parallel to the first direction X (or the second direction Y), and may have a length parallel to the second direction Y (or the first direction X). The first width W1 may be the same as or different from the second width W2. For example, the first width W1 may be greater than the second width W2. For example, the first portion 453a and the second portion 453b may include a linear shape or a strip shape having the same size or different sizes. Therefore, the piezoelectric vibration portion 453 may include a 2-2 composite structure, and thus may have a resonant frequency of 20kHz or less, but the embodiment is not limited thereto, and the resonant frequency of the piezoelectric vibration portion 453 may vary based on one or more of the shape, length, and thickness.

[0454] In the piezoelectric vibration portion 453, each of the plurality of first portions 453a and the plurality of second portions 453b may be disposed (or arranged) in parallel on the same plane (or the same layer). Each of the plurality of second portions 453b may be connected or attached to a second portion 453b adjacent thereto. For example, each of the plurality of second portions 453b may be configured to fill a gap between two adjacent first portions in the plurality of first portions 453a, and may be connected or attached to a second portion 453b adjacent thereto. Based on the side connection (or connection) of the first portion 453a and the second portion 453b, the piezoelectric vibration portion 453 may extend a desired size or length.

[0455] In the piezoelectric vibration portion 453 , a width (or size) W2 of each of the plurality of second portions 453 b may gradually decrease in a direction from a central portion to both peripheral edges (or both ends) of the piezoelectric vibration portion 453 or the vibration device 450 .

[0456] According to one embodiment of the present disclosure, the second portion 453b having the largest width W2 among the plurality of second portions 453b may be located at a portion where the highest stress may be concentrated when the piezoelectric vibration portion 453 or the vibration device 450 vibrates in the vertical direction Z (or thickness direction). The second portion 453b having the smallest width W2 among the plurality of second portions 453b may be located at a portion where relatively low stress may occur when the piezoelectric vibration portion 453 or the vibration device 450 vibrates in the vertical direction Z. For example, the second portion 453b having the largest width W2 among the plurality of second portions 453b may be disposed at the central portion of the piezoelectric vibration portion 453, and the second portion 453b having the smallest width W2 among the plurality of second portions 453b may be disposed at both edges or both peripheries of the piezoelectric vibration portion 453. Therefore, when the piezoelectric vibration portion 453 or the vibration device 450 vibrates in the vertical direction Z, interference of sound waves or overlap of resonance frequencies occurring in the portion where the highest stress is concentrated may be reduced or minimized. Therefore, the settling phenomenon of the sound pressure level occurring in the low-pitched vocal band can be reduced, thereby improving the flatness of the sound characteristics in the low-pitched vocal band. For example, the flatness of the sound characteristics may be the deviation level between the highest sound pressure and the lowest sound pressure.

[0457] In the piezoelectric vibration part 453, each of the plurality of first parts 453a may have a different size (or width). For example, the size (or width) of each of the plurality of first parts 453a may be gradually reduced or increased in a direction from the central part to both peripheries (or both ends) of the piezoelectric vibration part 453 or the vibration device 450. For example, in the piezoelectric vibration part 453, based on various natural vibration frequencies according to the vibration of each of the plurality of first parts 453a having different sizes, the sound pressure level characteristics of the sound may be enhanced, and the sound reproduction vocal cord may be enlarged.

[0458] Each of the plurality of second parts 453b may be disposed between the plurality of first parts 453a. Therefore, in the piezoelectric vibration portion 453 or the vibration device 450, the vibration energy of the link in the unit lattice of the first part 453a may be increased by the corresponding second part 453b. Therefore, the vibration may be increased, and the piezoelectric characteristics and flexibility may be ensured. For example, the second part 453b may include at least one or more of an epoxy-based polymer, an acrylic polymer, and a silicon-based polymer, but the embodiments of the present disclosure are not limited thereto.

[0459] The plurality of second portions 453b according to an embodiment of the present disclosure may be configured as organic material portions. For example, the organic material portion may be disposed between the inorganic material portions, and may absorb the impact applied to the inorganic material portion (or the first portion), may release the stress concentrated on the inorganic material portion to enhance the overall durability of the piezoelectric vibration portion 453 or the vibration device 450, and may provide flexibility to the piezoelectric vibration portion 453 or the vibration device 450.

[0460] The modulus and viscoelasticity of the plurality of second portions 453b according to one embodiment of the present disclosure may be lower than those of the first portion 453a, and thus the second portion 453b may enhance the reliability of the first portion 453a which is susceptible to impact due to its fragile characteristics. For example, the second portion 453b may include a material having a loss coefficient of about 0.01 to about 1.0 and a modulus of about 0.1 [GPa] to about 10 [GPa].

[0461] The organic material portion included in the second portion 453b may include one or more of an organic material, an organic polymer, an organic piezoelectric material, and an organic non-piezoelectric material having flexible characteristics compared to the inorganic material portion of the first portion 453a. For example, the second portion 453b may be referred to as an adhesive portion, an elastic portion, a bending portion, a damping portion, or a flexible portion having flexibility, but the embodiments of the present disclosure are not limited thereto.

[0462] A plurality of first portions 453a and a second portion 453b may be disposed on (or connected to) the same plane, and thus the piezoelectric vibration portion 453 of the vibration array 210 according to various embodiments of the present disclosure may have a single film type. For example, the piezoelectric vibration portion 453 may have a structure in which a plurality of first portions 453a are connected to one side of the piezoelectric vibration portion 453. For example, a plurality of first portions 453a may have a structure connected to the entire piezoelectric vibration portion 453. For example, the piezoelectric vibration portion 453 may have a structure in which a plurality of first portions 453a extend to one side of the piezoelectric vibration portion 453. For example, a plurality of first portions 453a may have a structure extending to the entire piezoelectric vibration portion 453. For example, the piezoelectric vibration portion 453 may vibrate in a vertical direction (or thickness direction) by the first portion 453a having vibration characteristics, and may be bent into a curved shape by the second portion 453b having flexibility. In addition, in the piezoelectric vibration section 453 according to various embodiments of the present disclosure, the size of the first part 453a and the size of the second part 453b can be adjusted based on the piezoelectric characteristics and flexibility required by the piezoelectric vibration section 453 or the vibration device 450. For example, when the piezoelectric vibration section 453 requires piezoelectric characteristics but not flexibility, the size of the first part 453a can be adjusted to be larger than the size of the second part 453b. As another example, when the piezoelectric vibration section 453 requires flexibility but not piezoelectric characteristics, the size of the second part 453b can be adjusted to be larger than the size of the first part 453a. For example, the size of the second part 453b and the size of the first part 453a can be one or more of width, length, and thickness. Therefore, the size of the piezoelectric vibration section 453 can be adjusted based on its required characteristics, and therefore, the piezoelectric vibration section 453 can be easily designed.

[0463] The first electrode portion E1 may be disposed at the first surface (or upper surface) of the piezoelectric vibration portion 453. The first electrode portion E1 may be commonly disposed or coupled to the first surface of each of the plurality of first portions 453a and the first surface of each of the plurality of second portions 453b, and may be electrically connected to the first surface of each of the plurality of first portions 453a. For example, the first electrode portion E1 may be a single electrode type disposed at the entire first surface of the piezoelectric vibration portion 453. For example, the first electrode portion E1 may have the same shape as that of the piezoelectric vibration portion 453, but the embodiments of the present disclosure are not limited thereto. As described above with reference to Fig.12 As described above, the first electrode portion E1 according to one embodiment of the present disclosure may include a transparent conductive material, a semi-transparent conductive material, or an opaque conductive material.

[0464] The second electrode portion E2 may be disposed at a second surface (or rear surface) opposite to the first surface of the piezoelectric vibration portion 453. The second electrode portion E2 may be commonly disposed or coupled to the second surface of each of the plurality of first portions 453a and the second surface of each of the plurality of second portions 453b, and may be electrically connected to the second surface of each of the plurality of first portions 453a. For example, the second electrode portion E2 may be a single electrode type disposed on the entire second surface of the piezoelectric vibration portion 453. For example, the second electrode portion E2 may have the same shape as that of the piezoelectric vibration portion 453, but embodiments of the present disclosure are not limited thereto. As described above with reference to Fig.12 As described above, the second electrode portion E2 according to one embodiment of the present disclosure may include a transparent conductive material, a semi-transparent conductive material, or an opaque conductive material.
