The relative sizes and depictions of these elements may be exaggerated for clarity, illustration, and convenience. DETAILED DESCRIPTION

[0047] Reference will now be made in detail to embodiments of the present disclosure, examples of which may be illustrated in the accompanying drawings.

[0048] The advantages and features of the present disclosure and their implementation methods will be explained by the following embodiments described with reference to the accompanying drawings. However, the present disclosure can be implemented in different forms and should not be interpreted as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art. In addition, the present disclosure is limited only by the scope of the claims.

[0049] The shapes, sizes, ratios, angles, and quantities disclosed in the drawings used to describe the embodiments of the present disclosure are merely examples, and therefore, the embodiments of the present disclosure are not limited to the details shown. The same reference numerals always refer to the same elements. In the following description, when it is determined that the detailed description of the related known technology unnecessarily obscures the focus of the present disclosure, the detailed description will be omitted.

[0050] When “including,” “having,” and “comprising” described in the present specification are used, another part may be added unless “only” is used. Terms in the singular form may include plural forms unless otherwise specified.

[0051] When explaining an element, the element is interpreted as including an error or tolerance range, even though there is no explicit description of such an error or tolerance range. When describing a positional relationship, for example, when the positional relationship between two parts is described as, for example, "on...", "above...", "below...", and "close to", one or more other parts may be arranged between the two parts, unless more restrictive terms such as "just" or "directly (directly)" are used. When describing a temporal relationship, for example, when the temporal sequence is described as, for example, "after...", "subsequently...", "next...", and "before...", discontinuous situations may be included, unless more restrictive terms such as "just", "immediately (immediately)" or "directly (directly)" are used.

[0052] It will be understood that although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the present disclosure.

[0053] 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 identify the corresponding element from other elements, and the basis, order or number of the corresponding elements should not be limited by these terms. The expression that an element is "connected", "coupled" or "bonded" to another element or layer means that the element or layer can not only be directly connected or bonded to the other element or layer, but also can be indirectly connected or bonded to the other element or layer using one or more intermediate elements or layers "disposed" between the elements or layers, unless otherwise specified.

[0054] The term "at least one" should be understood to include any and all combinations of one or more of the associated listed items. For example, the meaning of "at least one of the first, second, and third items" means all items proposed from two or more of the first, second, and third items and the combination of the first, second, or third items.

[0055] In the description of the embodiments, when a structure is described as being positioned "on or above" or "below or below" another structure, the description should be interpreted as including the case where the structures are in contact with each other and the case where a third structure is disposed therebetween. The size and thickness of each element shown in the drawings are given only for convenience of description, and the embodiments of the present disclosure are not limited thereto unless otherwise specified.

[0056] The features of the various embodiments of the present disclosure may be coupled or combined with each other in part or in whole, and may interoperate and be technically driven differently from each other, as can be fully understood by those skilled in the art. The embodiments of the present disclosure may be performed independently of each other, or may be performed together in a mutually dependent relationship.

[0057] Hereinafter, embodiments of a display device and a vehicle including the display device according to the present disclosure will be described in detail with reference to the accompanying drawings. When reference numerals are added to the elements of each figure, the same reference numerals may refer to the same elements even though the same elements are shown in other figures. In the following description, the detailed description may be omitted when it is determined that a detailed description of a related known function or configuration unnecessarily obscures the present disclosure. In addition, for ease of description, the scale of each element shown in the drawings is different from the actual scale, and therefore, is not limited to the scale shown in the drawings.

[0058] When the driving circuit of the display device is directly arranged on the rear surface of the display panel, the inventor has recognized the problem that the desired sound is not transmitted to the display panel due to the driving circuit when the vibration of the vibration generating module is transmitted to the display panel. In addition, when the vibration generating module is applied to an automobile display device with a relatively small size, the inventor has recognized the problem that the driving circuit is damaged by the vibration of the vibration generating module. Therefore, the inventor has conducted various experiments to reduce the damage to the driving circuit caused by the vibration generating module. Through various experiments, the inventor has invented a display device with a new structure, which prevents the driving circuit from being damaged by the vibration generating module, reduces the contact between the driving circuit and the display panel to reduce the vibration caused by the driving circuit, and enhances the sound of the vibration generating module.

[0060] Reference Figure 1 , the display device according to the embodiment of the present disclosure can output sound DVS (or display vibration sound) according to the vibration of the display panel 200 for displaying an image. Therefore, the display device according to the embodiment of the present disclosure can output sound DVS using the display panel 200 as a vibration plate. Therefore, the display device can output the sound DVS to the front area FD in front of the screen of the display panel 200, thereby transmitting accurate sound, improving sound quality, and increasing the immersive experience of the viewer or listener.

The plurality of pad portions 217 may be arranged at specific intervals in the first direction X. Thus, the flexible circuit film 310 may be connected to the plurality of pad portions 217 arranged at specific intervals, and thus, may be arranged at specific intervals in the first direction X. For example, the flexible circuit film 310 may be disposed in the pad portion 217 in the display panel 200 by a film attachment process using an anisotropic conductive film.

[0099] The flexible circuit film 310 may surround the rear surface of the display panel 200. The flexible circuit film 310 may be bent (or folded) from the pad portion 217 toward the rear surface of the display panel 200. For example, the other side of the flexible circuit film 310 may be disposed at a first rear peripheral portion (or first region) of the display panel 200. A middle portion (or bent portion) between one side and the other side of the flexible circuit film 310 may be bent (or folded) to surround one surface of the display panel 200.

[0100] The plurality of data driver ICs 320 may be mounted on the flexible circuit films 310, respectively, or may be mounted on the plurality of flexible circuit films 310, respectively. Each of the plurality of data driver ICs 320 may be mounted on the corresponding flexible circuit film 310 through a chip bonding process or a surface mounting process. Each of the plurality of data driver ICs 320 may convert input digital pixel data into an analog data signal based on a data control signal provided from the outside, and may provide the analog data signal to a corresponding pixel.

[0101] The PCB 330 may be commonly connected to the flexible circuit film 310. The PCB 330 may be electrically connected to the other side of the flexible circuit film 310 through a film attachment process using an anisotropic conductive film, and may be disposed on the first rear peripheral portion of the display panel 200 based on the bending of the flexible circuit film 310. The first rear peripheral portion of the display panel 200 may be a region of the rear surface of the display panel 200 where the flexible circuit film 310 and the PCB 330 are disposed. For example, the first rear peripheral portion of the display panel 200 may be one rear portion of the display panel 200. The PCB 330 may be between the rear surface of the display panel 200 and the first support 600. The PCB 330 according to an embodiment of the present disclosure may be spaced apart from the rear surface of the display panel 200 or floated from the rear surface of the display panel 200, and thus may not directly contact the rear surface of the display panel 200. For example, the rear surface of the PCB 330 may be placed so as not to contact the back plate 250 of the display panel 200.

[0102] For example, when the display device according to an embodiment of the present disclosure is applied to an automobile display device whose size is relatively smaller than that of a display device for a large-screen television (TV), the size of the PCB 330 on the rear surface of the display panel 200 may correspond to about 20% to 30% of the size of the display panel 200, and the PCB 330 may be placed or disposed in a vibration region of the display panel 200 based on the vibration of the vibration generating module 700. Therefore, in a case where the PCB 330 is disposed to directly contact the rear surface of the display panel 200, when the vibration of the display panel 200 for the sound DVS is directly transmitted to the PCB 330, the PCB 330 may be damaged or detachment between the PCB 330 and the flexible circuit film 310 may occur due to the vibration of the shaking of the PCB 330, and the data driving IC 320 may be damaged due to the vibration of the shaking of the flexible circuit film 310 caused by the vibration of the shaking of the PCB 330. Therefore, in the display device according to the embodiment of the present disclosure, the PCB 330 may be between the rear surface of the display panel 200 and the first support 600 so as not to directly contact the rear surface of the display panel 200. This may thereby prevent or minimize the transmission of vibration of the display panel 200 to the PCB 330, thereby preventing or minimizing damage to the PCB 330 caused by the vibration of the display panel 200, preventing or minimizing detachment between the flexible circuit film 310 and the PCB 330, and preventing or minimizing damage to the data driver IC 320.

[0103] The driving circuit 300 according to an embodiment of the present disclosure may include a control board 340 , a signal transmitting member 350 , a timing control circuit 360 , and a user connector 370 .

[0104] The control board 340 may be disposed on the rear surface of the first support 600 and may be connected to the PCB 330 through the signal transmission member 350. The control board 340 may be connected to the display host system (or display driving system) through the user connector 370. The control board 340 may provide the timing control circuit 360 with the timing synchronization signal and the video data respectively provided from the display host system, and may provide the digital pixel data output from the timing control circuit 360 to the data driving IC 320 through the signal transmission member 350, the PCB 330, and the flexible circuit film 310.

[0105] The control board 340 may further include a voltage generating circuit that generates various driving voltages required to drive the display device.

[0106] The timing control circuit 360 may be mounted on the control board 340 and may receive timing synchronization signals and video data respectively provided from the display host system through the user connector 370. For example, the timing synchronization signals may include a vertical synchronization signal, a horizontal synchronization signal, a data enable signal, and a main clock signal.

[0107] The timing control circuit 360 may generate a gate control signal for controlling the driving timing of the gate driving circuit and a data control signal for controlling the driving timing of each of the plurality of data driving ICs 320 based on the timing synchronization signal. For example, the gate control signal may include at least one gate start signal and a plurality of gate shift clocks. The data control signal may include a source start signal, a source shift clock, and a source output enable signal.

[0108] The timing control circuit 360 may be mounted on the front surface of the PCB 330 instead of the control board 340. In addition, the voltage generating circuit may be mounted on the front surface of the PCB 330 instead of the control board 340. In this case, the control board 340 may be omitted.

[0109] The driving circuit 300 according to an embodiment of the present disclosure may further include a touch driving circuit connected to a touch electrode layer of the display panel 200 .

[0110] The touch driving circuit may sense a user touch through each of a plurality of touch electrodes disposed on the touch electrode layer to generate touch raw data, and may send coordinate information about the user touch to a display host system based on the generated touch raw data.

[0111] The display host system may include a mainboard, various circuits mounted on the mainboard, various storage media, peripheral devices, a keyboard, and a power supply device. The various circuits mounted on the mainboard may include a central control circuit for processing various information, an image processing circuit for processing data according to the control of the central control circuit, and a sound processing circuit for processing sound according to the control of the central control circuit. The display host system may process various information, generate a timing synchronization signal and video data to provide the timing synchronization signal and the video data to the control board 340, and may generate a drive signal including a sound signal or a tactile feedback signal to provide the drive signal to the control board 340. For example, the sound signal may be synchronized with the video data, or may not be synchronized with the video data.

[0112] The display host system may execute an application associated with the touch coordinates corresponding to the coordinate information about the user's touch provided from the touch drive circuit, or may execute a user interface based on the user's touch drawing. In addition, the display host system may generate a drive signal including a tactile feedback signal corresponding to the coordinate information about the user's touch provided from the touch drive circuit.

[0113] The second support 400 may be disposed (or connected) between the rear surface of the display panel 200 and the driving circuit 300. The second support 400 may be disposed (or connected) between the rear surface of the display panel 200 and the PCB 330 of the driving circuit 300. The second support 400 may support the PCB 330 to separate the PCB 330 from the rear surface of the display panel 200. For example, the PCB 330 may be supported by the second support 400 and may be disposed between the rear surface of the display panel 200 and the first support 600.

[0114] The first surface (or front surface) of the second support 400 may be disposed (or connected) on the rear surface of the display panel 200, and the second surface (or rear surface) of the second support 400 opposite to the first surface (or front surface) may be disposed (or connected) on the rear surface of the PCB 330. For example, the first surface (or front surface) of the second support 400 may be disposed (or connected) on the back plate 250 which is the rearmost surface of the display panel 200. Therefore, the PCB 330 may be supported by the second support 400 and may be disposed (or connected) on the rear surface of the display panel 200 using the second support 400.

[0115] The second support 400 according to an embodiment of the present disclosure may include a vibration absorbing material or an elastic material that can be compressed to a certain extent that blocks or minimizes the transmission of vibration of the display panel 200 to the PCB 330. For example, the second support 400 may include a double-sided tape or a double-sided foam tape each including a vibration absorbing layer (or an elastic layer), but is not limited thereto.

[0116] According to another embodiment of the present disclosure, the second support 400 may include a double-sided conductive tape or a double-sided conductive foam tape. In this case, the PCB 330 may include a ground pattern exposed at its rear surface. For example, the second surface (or rear surface) of the second support 400 may be electrically connected to the ground pattern exposed at the rear surface of the PCB 330, and the back plate 250 of the display panel 200 may be electrically connected to the ground pattern exposed at the rear surface of the PCB 330. Therefore, the back plate 250 of the display panel 200 may perform the heat dissipation function of the display panel 200 and the function of grounding the ground pattern of the PCB 330.

[0117] The support frame 500 may be on the rear surface of the front member 100. For example, the support frame 500 may surround the side surface of the display panel 200 or the side surface of the driving circuit 300. For example, the support frame 500 may surround the side surface of the display panel 200 and the side surface of the driving circuit 300. The support frame 500 may accommodate the driving circuit 300 of the display panel 200. The support frame 500 may have the same shape as that of the front member 100. The support frame 500 may be on the outermost surface of the display device and may be directly exposed to the outside of the display device. For example, the support frame 500 may be an "outermost frame", "outermost mold material", "outermost mechanism", "guide frame", "guide panel", "edge frame" or "molding frame", but the term is not limited thereto.

[0118] The support frame 500 may support the first support 600 and may provide an air gap AG between the rear surface of the display panel 200 and the first support 600 , or may provide a receiving space or a storage space of the display panel 200 .

[0119] The support frame 500 may be disposed at a rear peripheral portion of the front member 100 through a first connection member (or a first coupling member) 501 .

[0120] The first connecting member 501 may be disposed (or connected) between the rear peripheral portion of the front member 100 and the support frame 500, and therefore, the support frame 500 may be disposed on the rear surface of the front member 100 (or connected to the rear surface of the front member 100). The first connecting member 501 according to an embodiment of the present disclosure may include an adhesive resin, a double-sided tape having an adhesive layer, or a double-sided foam pad having an adhesive layer, but is not limited thereto. In the first connecting member 501 according to an embodiment of the present disclosure, the adhesive resin or adhesive layer may include an acrylic or urethane-based adhesive material, but is not limited thereto. For example, in the first connecting member 501 according to an embodiment of the present disclosure, the adhesive resin or adhesive layer may include a urethane-based adhesive material having a relatively ductile property and unlike an acrylic-based adhesive material having a relatively high hardness property, for preventing the transmission of the vibration of the front member 100 to the support frame 500 or minimizing the transmission of the vibration of the front member 100 to the support frame 500.

[0121] The support frame 500 according to an embodiment of the present disclosure may include a frame portion 510 and a frame side portion 530 .

[0122] The frame portion 510 may be disposed on the rear surface of the front member 100. For example, the frame portion 510 may include an opening 515 disposed at a rear peripheral portion of the front member 100 to overlap with the display panel 200. The frame portion 510 may be disposed at a rear peripheral portion of the front member 100. For example, the frame portion 510 may have the same shape as that of the front member 100, but is not limited thereto. For example, the frame portion 510 may have a polygonal shape or a non-polygonal shape that is the same as that of the front member 100.

[0123] The opening 515 of the frame portion 510 may be defined by an inner surface of the frame portion 510. The opening 515 of the frame portion 510 may receive the display panel 200. The opening 515 of the frame portion 510 may have the same shape as that of the display panel 200, and may have a size greater than that of the display panel 200. The opening 515 of the frame portion 510 may have the same polygonal shape as that of the display panel 200 or a non-polygonal shape.

[0124] The frame side portion 530 may be disposed at the inner peripheral portion of the frame portion 510. For example, the frame side portion 530 may be vertically disposed at the inner peripheral portion of the frame portion 510 or protrude from the inner peripheral portion of the frame portion 510. The opening 515 may also be disposed in the frame side portion 530. For example, the frame portion 510 and the frame side portion 530 may each have a cross-sectional structure having a “┐┌” shape. The frame side portion 530 may surround the side surface of the display panel 200 and / or the driving circuit 300 of the display panel 200.

[0125] like Figure 4 As shown in , the support frame 500 according to an embodiment of the present disclosure may further include a plurality of connection portions 550 arranged at certain intervals on the outer side wall of the frame side portion 530. Each of the plurality of connection portions 550 may be a structure for placing the first support 600 in the support frame 500 (or connected to the support frame 500) and may protrude from the outer side wall of the frame side portion 530. For example, each of the plurality of connection portions 550 may include a hole. For example, the hole may be a screw hole, but is not limited thereto.

[0126] Reference Figures 2 to 5 , the first support 600 may be on the rear surface of the display panel 200. For example, the first support 600 may be supported by the peripheral portion of the support frame 500 and may cover (or overlie) the rear surface of the display panel 200. The first support 600 may support or accommodate (or store) the vibration generating module 700. The first support 600 may have the same shape as that of the display panel 200 and may be supported by the support frame 500.

[0127] The first support member 600 according to an embodiment of the present disclosure may serve as a support member for supporting the vibration generating module 700, and therefore, may include a metal material or a metal alloy material. For example, the first support member 600 may include one of Al, Al alloy, Mg alloy, iron-nickel (Fe-Ni) alloy, and stainless steel or its alloy, or may have a knot structure, but is not limited thereto. For example, the first support member 600 may have a thickness of 0.5 mm or more, but is not limited thereto. The first support member 600 may be a "support member", "back cover", "back cover" or "rear member", but the term is not limited thereto.

[0128] According to another embodiment of the present disclosure, the first support 600 may have a thickness of 0.5 mm or less to reduce the weight of the display device. In this case, since the rigidity of the first support 600 is weak due to the relatively thin thickness compared to the front member 100, the distortion of the first support 600 may occur due to the vibration of the vibration generating module 700. Due to this, the vibration of the vibration generating module 700 may not be normally transmitted to the front member 100. When the first support 600 does not have sufficient rigidity, the inventors have recognized the problem that the first support 600 absorbs a portion of the energy of the vibration generating module 700. For example, because the first support 600 absorbs the energy of the vibration generating module 700, insufficient vibration equal to the energy absorbed by the first support 600 may be transmitted to the display panel 200. Therefore, due to the insufficient vibration of the vibration generating module 700, the display panel 200 may be difficult to output sufficient sound. For this reason, when the energy or vibration of the vibration generating module 700 is lost, the inventors have recognized the problem that the display panel 200 is difficult to output the desired sound. Therefore, the inventors have conducted various experiments to increase or strengthen the rigidity of the first support member 600. Another structure may be provided in the first support member 600 to increase the rigidity of the first support member 600, but in this case, there may be a problem of thickening the display device. Through various experiments, the inventors provided a forming portion (or a receiving portion or a rigidity reinforcing structure) in the first support member 600 for increasing or strengthening the rigidity of the first support member 600 without increasing the thickness of the display device. In addition, the display device according to an embodiment of the present disclosure may further include at least one reinforcing portion for reinforcing the rigidity of the first support member 600. For example, at least one reinforcing portion may further include a reinforcing rod or a rigidity reinforcing structure. This will be described below.

[0129] The first support 600 according to an embodiment of the present disclosure may include a first plate 610 , a side portion 620 , and a forming portion 630 .

[0130] The first plate 610 (or the support plate) may be disposed on the rear surface of the display panel 200. For example, the first plate 610 may be disposed to face the rear surface (or back side) of the display panel 200 and may cover (or overlie) the rear surface of the display panel 200. The first plate 610 may be disposed at (or supported by) the frame side portion 530 of the support frame 500 through a plurality of first connection members 613. Each of the first connection members 613 may be a screw or a bolt, but is not limited thereto.

[0131] Each of the plurality of first connection members 613 may pass through a corresponding hole 611 of the plurality of holes 611 along the outer peripheral portion of the first plate 610, and may be disposed at a corresponding connection portion 550 of a plurality of connection portions 550 disposed at the frame side portion 530 of the support frame 500 (or connected to a corresponding connection portion 550 of a plurality of connection portions 550 disposed at the frame side portion 530 of the support frame 500), thereby placing the first plate 610 at the support frame 500 (or connected to the support frame 500). The first plate 610 may be disposed at the frame side portion 530 of the support frame 500 (or connected to the frame side portion 530 of the support frame 500) or supported by the frame side portion 530 of the support frame 500 using the plurality of first connection members 613. Therefore, the first plate 610 and the support frame 500 may each include a four-surface support structure, and therefore, four surfaces (or upper, lower, left, and right surfaces) of each of the front member 100, the support frame 500, and the first support 600 may have the same rigidity. Therefore, since each of the first plate 610 and the first support 600 has a four-surface support structure in which all four surfaces (or upper, lower, left and right sides) thereof are supported by the support frame 500, the four surfaces (or upper, lower, left and right peripheral portions) of each of the front member 100, the support frame 500 and the first support 600 can have the same rigidity. Therefore, the main vibration mode of the display panel 200 can be set near the vibration generating module 700, and the vibration area of ​​the vibration generating module 700 can match the maximum displacement position of the display panel 200, thereby enhancing the vibration efficiency of the vibration generating module 700 to enhance the sound pressure level, quality and reproduction band of the sound generated by the vibration of the display panel 200.

[0132] The side portion 620 (or support side portion) may be bent from the outer peripheral portion of the first plate 610. The side portion 620 may increase the rigidity of the first support 600 and may provide an accommodation (or storage) space on the first plate 610 for accommodating the frame side portion 530 of the support frame 500.

[0133] The side portion 620 may be on the rear surface of the support frame 500. For example, the side portion 620 may be provided at the rear peripheral portion of the support frame 500 using a second connection member (or a second coupling member) 621. For example, the side portion 620 may be provided at the frame portion 510 of the support frame 500 or connected to the frame portion 510 of the support frame 500 through the second connection member 621.

[0134] The second connecting member 621 may be between the side portion 620 and the frame portion 510 of the support frame 500, and the side portion 620 may be placed at the frame portion 510 of the support frame 500, connected or coupled to the frame portion 510 of the support frame 500. The second connecting member 621 according to an embodiment of the present disclosure may include an adhesive resin, a double-sided tape having an adhesive layer, or a double-sided foam pad having an adhesive layer, but is not limited thereto. The adhesive resin or adhesive layer of the second connecting member 621 according to an embodiment may include an acrylic or urethane-based adhesive material, but is not limited thereto. For example, the adhesive resin or adhesive layer of the second connecting member 621 may include a urethane-based adhesive material having a relatively ductile property, unlike an acrylic-based adhesive material having a relatively high hardness property. Therefore, the urethane-based adhesive material can prevent or minimize the transmission of vibrations based on the vibration of the vibration generating module 700 from the first support member 600 to the support frame 500, but the embodiments of the present disclosure are not limited thereto.

[0135] The forming portion 630 may be disposed on (or connected to) the first plate 610. The forming portion 630 may support the vibration generating module 700. The forming portion 630 may be disposed (or connected) to be concave or convex from the first plate 610. The forming portion 630 may increase or strengthen the rigidity of the first support 600. For example, the forming portion 630 may be disposed to be concave from the first plate 610 to reduce the increase in the thickness (or height) of the display device caused by the thickness (or height) of the vibration generating module 700 or minimize the increase in the thickness (or height) of the display device caused by the thickness (or height) of the vibration generating module 700, and thin the display device. However, the shape is not limited thereto.

[0136] The forming portion 630 may be concavely disposed (or connected) to have a quadrilateral shape from the front surface of the first plate 610 facing the rear surface of the display panel 200. The forming portion 630 may protrude from the first plate 610 in a rearward direction opposite to the forward direction toward the rear surface of the display panel 200, and therefore, may be concavely disposed on the first plate 610 (or connected to the first plate 610). However, embodiments of the present disclosure are not limited thereto. The forming portion 630 may be a "first forming portion", "groove portion", "recessed portion", "protruding portion", "engraved portion", "accommodating portion" or "rigidity reinforcing portion".

[0137] The forming portion 630 according to an embodiment of the present disclosure may include a bottom surface 631 facing the rear surface of the display panel 200 and an inclined surface 633 between the first plate 610 and the bottom surface 631. The inclined surface 633 may provide an accommodation space (or a supporting space) on the bottom surface 631, and may increase or strengthen the rigidity of the first support 600 and the rigidity of the first plate 610.

[0138] The first bearing 600 according to an embodiment of the present disclosure may further include a hole 640 in the formed portion 630. The hole 640 may be provided in the formed portion 630 to have a size and shape each capable of embedding or accommodating a portion of the rear surface of the vibration generating module 700 therein.

[0139] The hole 640 according to an embodiment of the present disclosure may include a first hole 641 in a first region of the forming portion 630 and a second hole 643 in parallel with the first hole 641 in a second region of the forming portion 630 .

[0140] The first hole 641 may be provided to pass through a first area of ​​the forming portion 630 overlapping the first rear area A1 of the display panel 200. For example, the first rear area A1 of the display panel 200 may be an area (or a left area) of the display panel 200 with respect to a center line (or a horizontal length center line) CL of the display panel 200 parallel to the first direction X.

[0141] The second hole 643 may be disposed through a second area of ​​the forming portion 630 overlapping the second rear area A2 of the display panel 200. For example, the second rear area A2 of the display panel 200 may be another area (or right area) of the display panel 200 with respect to the center line CL of the display panel 200.

[0142] like Figure 2 and Figure 3 As shown in , the first hole 641 and the second hole 643 according to an embodiment of the present disclosure may each have a circular shape, but are not limited thereto. For example, the first hole 641 and the second hole 643 may each have an elliptical shape or a polygonal shape, or may have a shape that enables a portion of the rear surface of the vibration generating module 700 to be embedded or accommodated therein.

[0143] The first support 600 according to an embodiment of the present disclosure may further include a cable hole 650 and a wire hole 660 in the formed portion 630 .

[0144] The cable hole 650 may be between the first hole 641 and the second hole 643 in the formed portion 630. The cable hole 650 may have a size and a shape each capable of allowing the signal transmitting member 350 to pass through the cable hole 650 to electrically connect the PCB 330 to the control board 340. A portion of the signal transmitting member 350 may be connected to the PCB 330 between the rear surface of the display panel 200 and the first support 600, and another portion of the signal transmitting member 350 may pass through the cable hole 650, may be unloaded to the rear surface of the first support 600, and may be connected to the control board 340.

[0145] The wire hole 660 may be in the bottom surface 631 of the forming portion 630 adjacent to the hole 640. The wire hole 660 may have a size and a shape each capable of enabling a driving signal cable of the vibration generating module 700 disposed between the rear surface of the display panel 200 and the first support 600 to be unloaded to the outside through the wire hole 660. The wire hole 660 according to an embodiment may include a first wire hole 661 in the bottom surface 631 of the forming portion 630 adjacent to the first hole 641 and a second wire hole 663 in the bottom surface 631 of the forming portion 630 adjacent to the second hole 643.

[0146] The first support 600 according to an embodiment of the present disclosure may further include a second forming portion 670 .

[0147] The second forming portion 670 according to an embodiment of the present disclosure may be on the first plate 610. For example, the second forming portion 670 may protrude from the central portion of the first plate 610 other than the peripheral portion toward the rear surface of the display panel 200. The second forming portion 670 may protrude to have an inclined surface from the central portion of the first plate 610 other than the peripheral portion toward the rear surface of the display panel 200, and thus, the rigidity of the first plate 610 may be reinforced. The second forming portion 670 may support the forming portion 630 (or the first forming portion 630). Therefore, the forming portion 630 may be arranged (or connected) to be recessed from the second forming portion 670. For example, the second forming portion 670 may be an "auxiliary forming portion", "groove portion", "recessed portion", "protruding portion", "engraving portion", "accommodating portion", "storage portion" or "rigidity reinforcing portion", but the term is not limited thereto. Therefore, the rigidity of the first support 600 may be increased due to the dual reinforcement structure including the forming portion 630 and the second forming portion 670.

[0148] According to another embodiment of the present disclosure, the second forming portion 670 may protrude from a central portion of the first plate 610 excluding a peripheral portion in a direction toward a rear surface (or back surface) of the first support 600 opposite to a direction toward a rear surface of the display panel 200, thereby reinforcing the rigidity of the first plate 610. The forming portion 630 may be concavely or convexly disposed at the second forming portion 670.

[0149] The first support 600 according to an embodiment of the present disclosure may further include a plurality of support portions 680. The plurality of support portions 680 may each be a "support pin," "bracket," or "support portion," but the term is not limited thereto.

[0150] A plurality of support portions 680 may be on the rear surface of the first plate 610. For example, each of the plurality of support portions 680 may be along a rear peripheral portion of the first plate 610. Each of the plurality of support portions 680 may be disposed at a support or a separate structure that supports the display device. Therefore, a display device according to an embodiment of the present disclosure may be supported by a support or a separate structure or be disposed at a support or a separate structure using a plurality of support portions 680.

[0151] Reference Figures 2 to 5 , the vibration generating module 700 may be disposed (or connected) between the first support 600 and the display panel 200. The vibration generating module 700 may be supported by the first support 600 and may vibrate the display panel 200. The vibration generating module 700 may vibrate based on a driving signal including a sound signal or a tactile feedback signal to directly vibrate the display panel 200, and thus, may output a sound DVS based on the vibration of the display panel 200 or may generate a tactile feedback (or tactile vibration) in response to a user's touch.

[0152] The vibration generating module 700 may be implemented as a sound generating device including a coil (or voice coil) and a magnet. The vibration generating module 700 according to an embodiment may include a bobbin and a coil wound around the bobbin, and the bobbin may contact the rear surface of the display panel 200 .

[0153] The vibration generating module 700 may include one sound generator or a plurality of sound generators 710 and 730. The sound generators 710 and 730 may be disposed in the shaped portion 630 in the first support 600 or accommodated (or stored) in the shaped portion 630 in the first support 600, and may vibrate the display panel 200. For example, the sound generators 710 and 730 may each include a bobbin and a coil wound around the bobbin, and the bobbin may contact the rear surface of the display panel 200.

[0154] The vibration generating module 700 according to an embodiment of the present disclosure may include a first sound generator 710 for vibrating a first rear surface of the display panel 200 and a second sound generator 730 for vibrating a second rear surface of the display panel 200 .

[0155] The first sound generator 710 may be supported by or accommodated (or stored) in the shaped portion 630 in the first support 600, and may be on the first rear surface of the display panel 200. The first sound generator 710 may vibrate based on a first driving signal including a sound signal or a tactile feedback signal to directly vibrate the first rear surface of the display panel 200, and thus, may generate a sound DVS based on the vibration of the display panel 200 or may generate a tactile feedback (or tactile vibration) in response to a user's touch. For example, a portion of the rear surface of the first sound generator 710 may be embedded or accommodated in the first hole 641 in the first region of the shaped portion 630, thereby reducing the thickness of the display device.

[0156] The second sound generator 730 may be supported by the forming part 630 provided in the first support 600 or accommodated (or stored) in the second region of the forming part 630 provided in the first support 600, and may be on the second rear surface of the display panel 200. The second sound generator 730 may vibrate according to the second driving signal including the sound signal or the tactile feedback signal to directly vibrate the second rear surface of the display panel 200, and thus, the sound DVS may be generated by the vibration of the display panel 200, or the tactile feedback (or tactile vibration) may be generated in response to the user's touch. For example, a portion of the rear surface of the second sound generator 730 may be embedded or accommodated (or stored) in the second hole 643 in the second region of the forming part 630, thereby reducing the thickness of the display device.

[0157] The first drive signal and the second drive signal may be the same or different. For example, the first drive signal may include a left sound signal or a first tactile feedback signal corresponding to the first area (or left area) A1 of the display panel 200. The second drive signal may include a right sound signal or a second tactile feedback signal corresponding to the second area (or right area) A2 of the display panel 200.

[0158] Each of the first sound generator 710 and the second sound generator 730 may be disposed at the first support 600 and may be symmetrical about a center line (or horizontal length center line) CL of the display panel 200, and may include substantially the same structure as each other. The first sound generator 710 and the second sound generator 730 may be a "vibration unit," "actuator," "stimulator," or "transducer," but the term is not limited thereto.

[0159] Therefore, the display device according to an embodiment of the present disclosure may output sound to the front region FD in front of the display panel 200 using the display panel 200 as a vibration plate for generating sound DVS, thereby improving sound quality and increasing the immersive experience of the viewer.

[0160] In a display device according to an embodiment of the present disclosure, the PCB 330 connected to the display panel 200 may be between the display panel 200 and the first support member 600 and may be spaced apart from the rear surface of the display panel 200, thereby preventing damage to the PCB 330 caused by vibration of the display panel 200 or minimizing damage to the PCB 330 caused by vibration of the display panel 200.

[0161] In addition, the display device according to the embodiment of the present disclosure may have a four-surface support structure in which all four surfaces (upper, lower, left and right) of each of the front member 100 and the first support 600 are supported by the support frame 500, the main vibration mode generated according to the vibration of the vibration generating module 700 may be set near the vibration generating module 700, and the vibration area of ​​the vibration generating module 700 may match the maximum displacement position of the display panel 200, thereby enhancing the vibration efficiency of the vibration generating module 700 to enhance the sound pressure level, quality and reproduction band of the sound generated by the vibration of the display panel 200. For example, the display device according to the embodiment of the present disclosure may output a sound of 100 Hz to 20 kHz at a sound pressure level of 65 dB or more based on the vibration of the display panel 200, and, for example, may output a sound of 150 Hz to 20 kHz at a sound pressure level of 75 dB or more.

[0162] Figure 6 yes Figure 4 1 is an enlarged view of a portion 'A' shown in FIG. 1 and is a diagram for describing the first sound generator 710 of the vibration generating module 700 according to an embodiment of the present disclosure.

[0163] Reference Figure 4 and Figure 6 , the first sound generator 710 of the vibration generating module 700 according to an embodiment of the present disclosure may be configured to vibrate the display panel 200 using a current of a driving signal including a sound signal or a tactile feedback signal, each of which is applied to the first sound generator 710 based on Fleming's left-hand rule of motors.

[0164] The first sound generator 710 according to an embodiment of the present disclosure may include a base plate 711 , a magnet 712 , a center rod 713 , a bobbin 714 , a coil 715 , an edge plate 716 , a damper 717 , and a terminal portion 718 .

[0165] The base plate 711 may be disposed at the first support 600 and may be a main body of the first sound generator 710. The base plate 711 may support the magnet 712, the center rod 713, and the edge plate 716. The base plate 711 may include a metal material having magnetism such as iron (Fe). The base plate 711 may be a "lower plate", "base frame", or "yoke", but the term is not limited thereto.

[0166] The base plate 711 may include a groove portion accommodating the magnet 712 and the bobbin 714. For example, the groove portion may be concavely provided from the upper surface of the base plate 711 to have a circular shape, but the shape is not limited thereto.

[0167] The base plate 711 according to an embodiment of the present disclosure may be on the bottom surface of the forming portion 630 of the first support 600 using a fixing member such as an adhesive or a double-sided tape.

[0168] According to another embodiment of the present disclosure, a portion of the rear surface of the base plate 711 may be embedded or accommodated in the first hole 641 in the formed portion 630 of the first support 600. In this case, the base plate 711 according to another embodiment of the present disclosure may include a rear protruding portion 711a embedded in the first hole 641 provided in the formed portion 630 of the first support 600. The rear protruding portion 711a may protrude from the base plate 711 toward the first support 600 to include a groove portion accommodating the magnet 712 and the bobbin 714, and may protrude to the outside of the rear surface of the rear cover 600 through the first hole 641 in the formed portion 630 of the rear cover 600 or may be exposed to the outside of the rear surface of the rear cover 600 through the first hole 641 in the formed portion 630 of the rear cover 600. Therefore, the heat generated by the driving (or vibration) of the first sound generator 710 can be dissipated through the rear surface of the base plate 711 based on air cooling, and the rear surface of the base plate 711 protrudes to the outside of the rear surface of the rear cover 600 through the first hole 641 or is exposed to the outside of the rear surface of the rear cover 600.

[0169] According to another embodiment of the present disclosure, the base plate 711 may be provided at the forming portion 630 of the first support 600 using a plurality of second connection members 701 passing through the bottom surface of the forming portion 630 of the first support 600. The plurality of second connection members 701 may be respectively in a plurality of holes passing through the bottom surface of the forming portion 630 in the corner portions of the base plate 711, and thus, the first sound generator 710 may be provided at the forming portion 630 of the first support 600.

[0170] The magnet 712 , the center rod 713 , the bobbin 714 , and the coil 715 may each be a magnetic circuit unit or a magnetic vibration unit on the base plate 711 to vibrate the display panel 200 .

[0171] The magnetic circuit unit according to an embodiment of the present disclosure may have an external magnetic type structure or a dynamic type structure including a magnet 712 arranged outward from the coil 715, or may have an internal magnetic type structure or a microstructure including a magnet 712 arranged inward from the coil 715. The first sound generator 710 including a magnetic circuit unit having an internal magnetic type structure may have an overall small size and low leakage magnetic flux. The first sound generator 710 according to an embodiment of the present disclosure may have an external magnetic type structure or an internal magnetic type structure. Hereinafter, an example in which the first sound generator 710 has an internal magnetic type structure will be described.

[0172] The magnet 712 according to an embodiment of the present disclosure may be inserted into the groove portion of the base plate 711. The magnet 712 may be a permanent magnet having a cylindrical shape capable of being inserted into the bobbin 714. According to an embodiment of the present disclosure, the magnet 712 may be implemented with a sintered magnet such as barium ferrite, and the material of the magnet 712 may include Fe2O3, BaCO3, a neodymium magnet, a strontium ferrite (Fe2O3) having an improved magnet component, and a sintered magnet such as barium ferrite. 12 O 19 The neodymium magnet may be one or more of an alloy cast magnet including Sr, Al, nickel (Ni) and cobalt (Co). For example, the neodymium magnet may be neodymium iron boron (Nd-Fe-B).

[0173] The bobbin 714 according to an embodiment of the present disclosure may be located on the base plate 711 to surround the magnet 712. The bobbin 714 may have a circular shape or an elliptical shape, but is not limited thereto. The elliptical shape may have an elliptical shape, a rectangular shape with rounded corners, or a non-circular curved shape having a width different from its height, but the embodiment is not limited thereto. For example, in the bobbin 714 having an elliptical shape, the ratio of the major axis diameter to the minor axis diameter may be set to 1.3:1 to 2:1. The bobbin 714 having an elliptical shape may improve the sound of the high vocal cords more than a circular shape, and may reduce the generation of heat caused by vibration, and therefore, may have excellent heat dissipation characteristics.

[0174] The coil 715 according to an embodiment of the present disclosure may be wound around the outer peripheral surface of the bobbin 714, and may be provided with an electric current (or voice current) of a drive signal from the outside. The coil 715 may be lowered or raised together with the bobbin 714. The coil 715 may be a "voice coil", but the term is not limited thereto. When an electric current is applied to the coil 715, the entire portion of the bobbin 714 may vibrate upward and downward based on the applied magnetic field generated around the coil 715 and the external magnetic field generated around the magnet 712 according to Fleming's motor left-hand rule, and may generate sound DVS or sound waves by the vibration of the display panel 200 caused by the vertical movement (or vibration) of the bobbin 714.

[0175] According to an embodiment of the present disclosure, when the coil 715 is wound around the outer peripheral surface of the bobbin 714, the heat generated in the coil 715 may be transferred to the bobbin 714, and the coil 715 may include a material having relatively good heat dissipation characteristics for reducing the image quality defects of the display panel 200 due to the heat of the bobbin 714. In addition, because the bobbin 714 vibrates upward and downward, horizontal vibration may be generated due to vertical vibration, and the horizontal vibration of the bobbin 714 may be affected by the weight of the bobbin 714. The weight of the bobbin 714 may be affected by the weight of the coil 715, and therefore, when the weight of the coil 715 is reduced, the horizontal vibration of the bobbin 714 may be reduced. Therefore, considering the heat transferred to the bobbin 714 and the horizontal vibration of the bobbin 714, the coil 715 may have relatively good heat dissipation characteristics because its thermal conductivity is better than that of copper, which is a material of a general coil, and may include an Al material, which has relatively good heat dissipation characteristics and is relatively lightweight compared to copper.

[0176] In addition, in aluminum, since oxides are formed in the air, welding may not be easy when manufacturing the first sound generator 710. Therefore, the coil 715 according to an embodiment of the present disclosure may include an 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 Cu, Ag, and gold (Au). For example, the coil 715 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, and therefore, the increase in the weight of the coil 715 may not be greatly affected. The weight of the coil 715 according to an embodiment of the present disclosure can be reduced by about 60% compared to a coil including only Cu or Cu wire.

[0177] According to an embodiment of the present disclosure, the bobbin 714 may include a structure including a material obtained by processing pulp or paper, Al or Mg or an alloy thereof, or a synthetic resin such as polyimide. For example, the bobbin 714 may be implemented with a polyimide film having relatively good heat dissipation characteristics and relatively light weight to prevent local image quality defects of the display panel 200 caused by heat generated in the coil 715.

[0178] The polyimide film may have physical properties that do not change over a wide temperature range of -273°C to 400°C, and may have heat resistance, electrical insulation, flexibility, and non-uniformity. In addition, because the polyimide film has good thermal and mechanical rigidity, the polyimide film may enhance the reliability of the bobbin 714, and may reduce the generation of heat caused by the vibration of the bobbin 714 based on excellent heat dissipation characteristics. For example, the polyimide film may be KAPTON, and may be a condensation of 1,2,4,5-pyromellitic dianhydride and 4,4'-diaminodiphenyl ether, but is not limited thereto.

[0179] The center rod 713 may be accommodated in or inserted into the bobbin 714 and may guide the raising or lowering of the bobbin 714. For example, since the center rod 713 is inserted into the bobbin 714, the outer peripheral surface of the center rod 713 is surrounded by the bobbin 714. The center rod 713 may be a "height guide" or a "rod member", but the term is not limited thereto.

[0180] The edge plate 716 may be provided at the front peripheral portion of the base plate 711 and may support the damper 717. The edge plate 716 according to an embodiment of the present disclosure may be provided at the front peripheral portion of the base plate 711 to have a certain height and the same shape as the shape of the bobbin 714. According to another embodiment of the present disclosure, the edge plate 716 may include a hollow portion provided at the front peripheral portion of the base plate 711 to have a certain height and the same shape as the shape of the bobbin 714.

[0181] The damper 717 may be located between the edge plate 716 and the magnetic circuit unit. For example, the damper 717 may be located between the edge plate 716 and the bobbin 714. The damper 717 may be a "tripod", "suspension" or "edge", but the term is not limited thereto.

[0182] A portion of the damper 717 according to an embodiment of the present disclosure may be connected to the edge plate 716, and another portion of the damper 717 may be connected to the upper outer surface of the bobbin 714. The damper 717 may have a pleat structure between a portion and another portion thereof, and may contract and relax based on the vertical movement of the bobbin 714 to control the vibration of the bobbin 714. The damper 717 may be connected between the bobbin 714 and the edge plate 716 and may limit the vibration distance of the bobbin 714 with a restoring force. For example, when the bobbin 714 vibrates a certain distance or more or a certain distance or less, the bobbin 714 may be restored to an original position by the restoring force of the damper 717.

[0183] Because the first sound generator 710 is located between the display panel 200 and the first support 600, the first sound generator 710 can have a relatively thin thickness to reduce the thickness of the display device or make the display device thinner. Thus, when the height (or thickness) of the bobbin 714 is reduced, the sound pressure level may be reduced. Therefore, in order to solve the problem of reduced sound pressure level due to the reduction in the height of the bobbin 714, the first sound generator 710 can be configured with a structure in which the area of ​​the damper 717 arranged near the bobbin 714 is wide. In the case where the area of ​​the damper 717 is increased, the space for setting the wire for applying current to the coil 715 can be narrowed, thereby causing interference between the wire and the damper 717. Therefore, the damper 717 can be formed by a conductor, and thus can perform the function of a wire.

[0184] The damper 717 according to an embodiment of the present disclosure may include a metal material electrically connected to the coil 715. For example, the damper 717 may be formed of stainless steel or Cu, but is not limited thereto.

[0185] The terminal portion 718 may include a pair of terminals on a portion of the base plate 711 and electrically connected to the damper 717. The terminal portion 718 may overlap the first wire hole 661 in the formed portion 630 of the first support 600, and may be exposed at the outer side of the rear surface of the first support 600. The pair of terminals in the terminal portion 718 may be electrically connected to a driving signal cable passing through the first wire hole 661, and a driving signal may be provided from a display host system through the driving signal cable.

[0186] The first sound generator 710 according to an embodiment of the present disclosure may further include a bobbin protection member 719 .

[0187] The bobbin protection member 719 may be disposed (connected) on the front surface (or front end portion) of the bobbin 714, and may transmit the raising and lowering motion (or vibration) of the bobbin 714 to the rear surface of the display panel 200. The bobbin protection member 719 according to an embodiment of the present disclosure may have an annular shape on the front surface of the bobbin 714, a disc shape covering the entire front surface of the bobbin 714, or a notch shape surrounding the front surface and upper outer surface of the bobbin 714, but the shape is not limited thereto. For example, the bobbin protection member 719 may be a "bobbin ring", but the term is not limited thereto.

[0188] The bobbin protection member 719 may be disposed on (or coupled to) the rear surface of the display panel 200 using a first adhesive member. The first adhesive member may be located between the back plate 250 of the display panel 200 and the bobbin protection member 719. The adhesive member according to an embodiment of the present disclosure may include an adhesive or a double-sided tape, but is not limited thereto.

[0189] The second sound generator 730 of the vibration generating module 700 according to an embodiment of the present disclosure may be disposed at the first support 600, and may be symmetrical with the first sound generator 710 with respect to the center line (or horizontal length center line) CL of the display panel 200. The second sound generator 730 may include a structure substantially the same as that of the first sound generator 710, and thus, a repeated description thereof is omitted.

[0190] Figure 7 yes Figure 4 0 is another enlarged view of a portion 'A' shown in FIG. 1 and shows an example in which a blocking member is disposed between the display panel and the vibration generating module. Hereinafter, a description of the same elements except for the blocking member and related elements will be briefly given or omitted.

[0191] Reference Figure 7 , the display device according to an embodiment of the present disclosure may further include a blocking member 720 disposed between the display panel 200 and the vibration generating module 700. The first sound generator 710 according to an embodiment of the present disclosure may further include a blocking member 720.

[0192] The blocking or shielding member 720 (or heat blocking member or heat insulating member) may block or minimize heat transfer to the display panel 200 generated in the first sound generator 710 due to the driving (or vibration) of the first sound generator 710, and thus, may prevent or minimize a local temperature rise of the display panel 200 caused by the heat generated in the first sound generator 710, thereby preventing image quality defects of the display panel 200 caused by a rapid temperature difference in a local area of ​​the display panel 200 overlapping with the first sound generator 710. For example, heat generated in the coil 715 and the like of the first sound generator 710 may not be transferred to the display panel 200 through the blocking member 720, and may be diffused and dissipated through the first support 600 and the heat dissipation member 130 via the base plate 711, or may be dissipated to the first support 600 based on air cooling through the rear surface (or back side) of the base plate 711. The blocking member 720 may be configured to have a size that is the same as or similar to that of the first sound generator 710, but is not limited thereto. For example, the blocking member 720 may be configured to have a size that is the same as or similar to that of the pixel array substrate 210 .

[0193] For example, the blocking member 720 may have a film type or a plate type, each of which includes one of polyethylene, polyvinyl pyrrolidone (PVP), polyethylene oxide (PEO), polyvinyl alcohol (PVA), polyvinyl acetate (PVAc), polylactic acid (PLA), polyamide (PA), polyester (PE), and polypropylene (PP), but is not limited thereto. As another example, the blocking member 720 may have a film type or a plate type, each of which includes one of rubber, silicon, fiber reinforced plastic, and a composite resin including fiber reinforced plastic, but is not limited thereto. For example, the fiber reinforced plastic may include one of carbon fiber reinforced plastic, glass fiber reinforced plastic, and graphite fiber reinforced plastic, or a combination thereof, but is not limited thereto.

[0194] The blocking member 720 according to an embodiment of the present disclosure may be located between the rear surface of the display panel 200 and the bobbin 714 of the first sound generator 710, and in this case, the bobbin protection member 719 may be omitted. For example, the blocking member 720 may be located on the bobbin 714 of the first sound generator 710, and may be provided on the back plate 250 of the display panel 200 or connected (or coupled) to the back plate 250 of the display panel 200 by an adhesive member.

[0195] According to another embodiment of the present disclosure, the blocking member 720 may be located between the back plate 250 of the display panel 200 and the bobbin protection member 719 of the first sound generator 710. For example, the blocking member 720 may be disposed on (or connected to) the front surface of the bobbin protection member 719, and may be disposed on the back plate 250 of the display panel 200 or connected (or coupled) to the back plate 250 of the display panel 200 by an adhesive member.

[0196] The blocking member 720 may be located between the display panel 200 and the second sound generator 730 of the vibration generating module 700. For example, the blocking member 720 may be located between the rear surface of the display panel 200 and the bobbin 714 of the second sound generator 730, and in this case, the bobbin protection member 719 of the second sound generator 730 may be omitted. As another example, the blocking member 720 may be located between the back plate 250 of the display panel 200 and the bobbin protection member 719 of the second sound generator 730.

[0197] The display device according to an embodiment of the present disclosure may include a blocking member 720 between the display panel 200 and the vibration generating module 700, and thus, a local temperature increase of the display panel 200 caused by heat generated in the vibration generating module 700 may be prevented or minimized, thereby preventing image quality defects of the display panel 200 caused by a rapid temperature difference in a local area of ​​the display panel 200 overlapping with the vibration generating module 700.

[0198] Figure 8 yes Figure 4 Another enlarged view of the portion 'A' shown in FIG. 1 and showing an example in which the arrangement or connection (or coupling) structure between the vibration generating module and the first support is modified. Hereinafter, a description of the same elements other than the arrangement or connection (or coupling) structure between the vibration generating module and the first support will be briefly given or omitted.

[0199] Reference Figure 8 According to an embodiment of the present disclosure, the first sound generator 710 of the vibration generating module 700 can be set at the forming portion 630 of the first support 600 using a plurality of second connecting members 701, and is supported by or connected (or coupled) to the forming portion 630 of the first support 600.

[0200] Each of the plurality of second connection members 701 may be connected to or disposed on the inner surface of the first support 600 through the vibration generating module 700, and thus, the vibration generating module 700 may be supported by the first support 600 or connected (or coupled) to the first support 600. For example, each of the plurality of second connection members 701 may be disposed on or connected to the bottom surface of the forming portion 630 through the outer peripheral portion of the base plate 711 of the first sound generator 710 using an internal connection method. Therefore, the first sound generator 710 may be supported by or connected (or coupled) to the bottom surface of the forming portion 630.

[0201] The first support 600 may further include a plurality of boss portions 635 on the bottom surface of the first forming portion 630. Each of the plurality of boss portions 635 may include a hole protruding from the bottom surface of the forming portion 630 overlapping the peripheral portion of the base plate 711 and connected to a corresponding second connection member 701 of the plurality of second connection members 701. For example, each of the plurality of boss portions 635 may be inserted into or accommodated in a corresponding boss groove of a plurality of boss grooves provided at the peripheral portion of the base plate 711 of the first sound generator 710.

[0202] Similar to the first sound generator 710, the second sound generator 730 of the vibration generating module 700 according to an embodiment of the present disclosure can be set on the bottom surface of the forming part by an internal connection method using a connecting member, and supported by the bottom surface of the forming part or connected (or coupled) to the bottom surface of the forming part.

[0203] The vibration generating module 700 according to the embodiment of the present disclosure can be connected (or coupled) to the first support 600 according to the internal connection mode using the plurality of second connection members 701 to increase the supporting force or coupling force between the vibration generating module 700 and the first support 600, and when the vibration generating module 700 is being driven (or vibrated), the noise caused by the undesired vibration between the vibration generating module 700 and the first support 600 can be prevented. In addition, since each of the plurality of second connection members 701 for supporting the vibration generating module 700 or coupling the vibration generating module 700 to the first support 600 is not exposed to the rear surface (or back side) of the first support 600, the display device according to the embodiment of the present disclosure can have a back structure with a clean rear, thereby enhancing the aesthetic feeling of the design. In addition, in the display device according to the embodiment of the present disclosure, the thickness of the vibration generating module 700 can be reduced, and therefore, the vibration generating module 700 can be disposed between the display panel 200 and the first support 600, thereby reducing the thickness of the display device. In addition, since the vibration generating module 700 according to an embodiment of the present disclosure is disposed between the display panel 200 and the first support 600, the rear surface of the first support 600 may not need to be provided with a hole for the vibration generating module 700, thereby enhancing the degree of freedom based on the size or model of the display device.

Therefore, the first sound generator 710 may be supported by or coupled to the bottom surface of the forming portion 630. Therefore, the first sound generator 710 may be disposed on the bottom surface of the forming portion 630 by a two-way connection using the second connection members 701 and the coupling members 703, and may be supported by or connected (or coupled) to the bottom surface of the forming portion 630.

[0219] A pair of bridges 413 may be bent from both sides of the second plate 411 and may be connected to the support frame 500, thereby supporting the second plate 411. For example, a pair of bridges 413 may be bent from both ends or both sides of the second plate 411 and may be connected to the support frame 500, thereby supporting the second plate 411. A pair of bridges 413 may be disposed at the frame side portion 530 of the support frame 500 using a plurality of third connection members 415. Each of the third connection members 415 may be a screw or a bolt, but is not limited thereto. Therefore, the second plate 411 may be supported by a pair of bridges 413 connected to or disposed at the support frame 500, and may therefore be spaced a certain distance from the rear surface of the display panel 200.

[0220] The second bearing 400 according to an embodiment of the present disclosure may further include a buffer member 450 .

[0225] For example, the PCB 330 (or the first PCB or the main PCB) may have a mass and thus may be used as a mass on the first area of ​​the display panel 200. Therefore, when the display panel 200 is vibrating, a vibration deviation or a maximum vibration displacement deviation may be generated in the first area where the PCB 330 is disposed and the third area where the PCB 330 is not disposed. Therefore, the balancing member 800 may be used as a mass on the third area where the PCB 330 is not disposed, and thus, the vibration balance between the first area where the PCB 330 is disposed and the third area where the PCB 330 is not disposed may be adjusted, thereby improving the vibration efficiency of the vibration generating module 700.

[0226] The balancing member 800 according to an embodiment of the present disclosure may include a second PCB 810 and a third adhesive member 830 .

[0231] The third adhesive member 830 according to an embodiment of the present disclosure may include a vibration absorbing material or an elastic material that can be compressed to a certain extent for preventing or minimizing noise generated by vibration of the second PCB 810 caused by the vibration of the display panel 200. For example, the third adhesive member 830 may include a material for blocking or minimizing the transmission of vibration of the display panel 200 to the PCB 330. For example, the third adhesive member 830 may include a double-sided tape or a double-sided foam tape, each including a vibration absorbing layer (or an elastic layer), but is not limited thereto.

[0232] Therefore, a display device according to another embodiment of the present disclosure may have Figures 1 to 12 The effect is the same as that of the display device shown in and the balancing member 800 can be used to achieve vibration balance of the display panel 200, thereby improving the vibration efficiency of the vibration generating module 700 and increasing the reproduction band and sound pressure level of the sound generated by the vibration of the display panel 200.
