Description

[0001] Cross-reference to related applications

[0002] This application claims the benefit of Korean Patent Application No. 10-2021-0184066, filed on December 21, 2021, which is incorporated herein by reference as fully set forth herein. Technical Field

[0003] This disclosure relates to apparatuses, and more specifically to apparatuses for generating vibrations that simplify the connection structure between a vibration device and an audio controller. Background Technology

[0004] The device includes a separate loudspeaker or sound unit for providing sound. When loudspeakers are placed in the device, the design and spatial arrangement of the device become limited due to the space occupied by the loudspeakers.

[0005] A loudspeaker used in a device can be, for example, an actuator comprising a magnet and a coil. However, when an actuator is used in a device, there is a drawback of its thickness. Piezoelectric devices, which aim to achieve a thinner thickness, are attracting widespread attention.

[0006] Due to their fragile nature, piezoelectric devices are easily damaged by external impacts, resulting in low reliability of sound reproduction. Furthermore, when loudspeakers using piezoelectric devices are applied to flexible devices, their fragility can cause damage.

[0007] Furthermore, due to the unloading hole of the vibration signal cable of the piezoelectric device, the stiffness and heat dissipation quality are reduced, the position of the piezoelectric device is restricted, and heat is generated due to the vibration signal cable when driving the piezoelectric device.

[0008] The information disclosed in the Background section was already known to the inventors of the inventive concept prior to the implementation of this disclosure, or is technical information obtained in the course of implementing this disclosure. Therefore, it may contain information that does not constitute prior art already known to the public in this country. Summary of the Invention

[0011] Another aspect of this disclosure is intended to provide a vibration device with a simplified structure and an apparatus including the vibration device.

However, this disclosure may be implemented in different forms, and it should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to make this disclosure detailed and complete, and to fully convey the scope of this disclosure to those skilled in the art. Furthermore, this disclosure is defined only by the scope of the claims.

[0042] The shapes, dimensions, ratios, angles, and quantities disclosed in the accompanying drawings, which are used to describe embodiments of this disclosure, are merely examples, and therefore, embodiments of this disclosure are not limited to the details shown. Throughout the specification, the same reference numerals refer to the same elements. In the following description, detailed descriptions of relevant known functions or configurations will be omitted where it is determined that such detailed descriptions unnecessarily obscure the essential points of this disclosure.

[0043] When using terms such as “comprise,” “have,” “include,” “contain,” “form,” “comprise,” “form of,” etc., one or more additional elements may be added unless a term such as “only” is used. Unless the context explicitly indicates otherwise, singular terms may include plural forms.

[0048] The terms “first horizontal axis direction,” “second horizontal axis direction,” and “vertical axis direction” should not be interpreted solely based on the geometric relationship that the directions are perpendicular to each other, but may refer to directions that have a broader directional nature within the scope of the functional operability of the components of this disclosure.

[0049] The term "at least one" should be understood to include any and all combinations of one or more associated enumerated items. For example, "at least one of the first, second, and third items" means a combination of all items derived from two or more of the first, second, and third items, as well as the first, second, or third item.

[0054] For example, the vibrating member 100 can output sound based on the vibration of the vibrating device 200. The vibrating device 200 can output sound by using the vibrating member 100 as a vibrating plate. For example, the vibrating device 200 can output sound toward the front surface of the vibrating member 100 by using the vibrating member 100 as a vibrating plate. For example, the vibrating device 200 can generate sound such that the sound travels toward the front surface of the vibrating member 100 or the display panel. The vibrating device 200 can cause the vibrating member 100 to vibrate to output sound. For example, the vibrating device 200 can directly cause the vibrating member 100 to vibrate to output sound. For example, the vibrating member 100 can be a vibrating object, a display panel, a vibrating panel, or a front member, but the embodiments of this disclosure are not limited thereto.

In the top-emitting type, visible light emitted from the pixel array layer can illuminate the substrate in a forward direction to enable image display, while in the bottom-emitting type, visible light emitted from the pixel array layer can illuminate the substrate in a rearward direction to enable image display.

[0058] The vibration member 100 according to embodiments of the present disclosure may include a pixel array portion disposed on a substrate. The pixel array portion may include a plurality of pixels that display an image based on a signal supplied through each of the signal lines. The signal lines may include gate lines, data lines, and pixel drive power lines, etc., but embodiments of the present disclosure are not limited thereto.

[0059] Each of the plurality of pixels may include a pixel circuit layer comprising: a driving TFT disposed in a pixel region configured with a plurality of gate lines and / or a plurality of data lines; an anode electrode electrically connected to the driving TFT; a light-emitting device formed on the anode electrode; and a cathode electrode electrically connected to the light-emitting device.

A cathode electrode (or common electrode) may be connected to the OLED layer disposed in each pixel region. For example, the OLED layer may have a stacked structure comprising two or more structures or a single structure containing the same color. In another embodiment of this disclosure, the OLED layer may have a stacked structure comprising two or more structures containing one or more different colors for each pixel. The two or more structures containing one or more different colors may be configured as one or more of blue, red, yellow-green, and green, or combinations thereof, but embodiments of this disclosure are not limited thereto. Examples of combinations may include blue and red, red and yellow-green, red and green, and red / yellow-green / green, but embodiments of this disclosure are not limited thereto. Furthermore, combinations may be applied regardless of their stacking order. The stacked structure comprising two or more structures having the same color or one or more different colors may also include a charge-generating layer between the two or more structures. The charge generation layer can have a PN junction structure and can include an N-type charge generation layer and a P-type charge generation layer.

The cathode electrode may be connected to the second terminal of the miniature LED device disposed in each pixel region.

[0064] An encapsulation portion can be formed on a substrate to surround the pixel array portion, thereby preventing oxygen or water from penetrating into the light-emitting device layer of the pixel array portion. The encapsulation portion according to embodiments of this disclosure can be formed as a multilayer structure with alternating organic and inorganic material layers, but embodiments of this disclosure are not limited thereto. The inorganic material layer prevents oxygen or water from penetrating into the light-emitting device layer of the pixel array portion. The organic material layer can be formed to have a thickness relatively thicker than the inorganic material layer to cover particles generated during the manufacturing process. For example, the encapsulation portion may include a first inorganic layer, an organic layer on the first inorganic layer, and a second inorganic layer on the organic layer. The organic layer may be a particle covering layer, but the terminology is not limited thereto. A touch panel can be disposed on the encapsulation portion, or the touch panel may be disposed on the rear surface of the pixel array portion or disposed within the pixel array portion.

[0065] The vibrating member 100 according to embodiments of this disclosure may include a first substrate, a second substrate, and a liquid crystal layer. The first substrate may be an upper substrate or a TFT array substrate. For example, the first substrate may include a pixel array (or display section or display area) comprising a plurality of pixels disposed in a pixel area configured by a plurality of gate lines and / or a plurality of data lines. Each of the plurality of pixels may include a TFT connected to the gate lines and / or data lines, a pixel electrode connected to the TFT, and a common electrode formed adjacent to the pixel electrode and supplied with a common voltage.

[0066] The first substrate may further include a pad portion disposed at its first edge (or non-display portion) and a gate driving circuit disposed at its second edge (or second non-display portion).

[0067] The pad portion can supply externally supplied signals to the pixel array portion and / or the gate drive circuit. For example, the pad portion may include: multiple data pads connected to multiple data lines via multiple data link lines; and / or multiple gate input pads connected to the gate drive circuit via gate control signal lines. For example, the size of the first substrate may be larger than the size of the second substrate, but the terminology is not limited thereto.

[0068] The gate driving circuit can be embedded (or integrated) into the second edge of the first substrate to connect to multiple gate lines. For example, the gate driving circuit can be implemented using a shift register comprising transistors formed by the same process as TFTs disposed in the pixel region. According to another embodiment of this disclosure, the gate driving circuit may not be embedded in the first substrate, but can be disposed in an IC-type panel driving circuit.

[0069] The second substrate can be a lower substrate or a color filter array substrate. For example, the second substrate may include: a pixel pattern (or pixel definition pattern) capable of including an opening region overlapping with a pixel region formed in the first substrate; and a color filter layer formed in the opening region. The second substrate may have a smaller size than the first substrate, but embodiments of this disclosure are not limited thereto. The second substrate may overlap with a portion of the first substrate other than the first edge. The second substrate may be bonded to a portion of the first substrate other than the first edge using a sealant, wherein the liquid crystal layer is located between the second substrate and the first substrate.

[0070] A liquid crystal layer may be disposed between a first substrate and a second substrate. The liquid crystal layer may include liquid crystal, wherein the orientation of the liquid crystal molecules changes based on an electric field generated by a common voltage and a data voltage applied to the pixel electrodes of each pixel.

[0071] The second polarizing member can be attached to the lower surface of the second substrate and can polarize light incident from the backlight and traveling in parallel to the liquid crystal layer. The first polarizing member can be attached to the upper surface of the first substrate and can polarize light passing through the first substrate and emitted to the outside.

[0072] The vibrating member 100 according to embodiments of this disclosure can drive the liquid crystal layer using an electric field generated by a common voltage and a data voltage applied to each pixel, thereby displaying an image based on light passing through the liquid crystal layer.

[0073] In another embodiment of the vibrating member 100 according to the present disclosure, the first substrate may be a color filter array substrate, and the second substrate may be a TFT array substrate. For example, the vibrating member 100 according to another embodiment of the present disclosure may have a form in which the vibrating member 100 according to the embodiment of the present disclosure is vertically reversed. In this case, the pad portion of the vibrating member 100 according to another embodiment of the present disclosure may be covered by a separate mechanism.

[0074] According to another embodiment of the present disclosure, the vibration member 100 may include a bending portion that is bent or flexed to have a specific radius of curvature or a curved shape.

[0075] The bending portion of the vibrating member 100 can be implemented at one or more of its parallel edge portions and other edge portions. One edge portion and another edge portion of the vibrating member 100 implementing the bending portion may only include the non-display area IA, or may include the display area AA and the edge portion of the non-display area IA. The vibrating member 100 including the bending portion implemented by bending the non-display area IA can have a single-sided edge bending structure or a double-sided edge bending structure. Furthermore, the vibrating member 100 including the edge portion of the display area AA and the bending portion implemented by bending the non-display area IA can have a single-sided active bending structure or a double-sided active bending structure.

[0076] The vibration device 200 can cause the vibrating member 100 to vibrate at the rear surface of the vibrating member 100, and thus can provide sound and / or tactile feedback to the user based on the vibration of the vibrating member 100. The vibration device 200 can be implemented at the rear surface of the vibrating member 100 to directly cause the vibrating member 100 to vibrate. For example, the vibration device 200 can be a vibration generating device, a displacement device, a sound device, or a sound generating device, but the terminology is not limited thereto.

[0077] In embodiments of this disclosure, the vibration device 200 may vibrate based on a vibration drive signal synchronized with an image displayed by the vibration member 100, thereby causing the vibration member 100 to vibrate. According to another embodiment of this disclosure, the vibration device 200 may vibrate based on a haptic feedback signal (or haptic feedback signal) synchronized with a user touch applied to a touch panel (or touch sensor layer) disposed on or embedded in the vibration member 100, and thus cause the vibration member 100 to vibrate. Therefore, the vibration member 100 may vibrate based on the vibration of the vibration device 200 to provide one or more of auditory and haptic feedback to a user (or viewer).

[0078] The vibration device 200 can cause the display panel or the vibrating member 100 to vibrate. For example, the vibration device 200 can be implemented on the rear surface of the vibrating member 100 to directly cause the display panel or the vibrating member 100 to vibrate. For example, the vibration device 200 can cause the vibrating member 100 to vibrate at the rear surface of the display panel or the vibrating member 100, and thus can provide sound and tactile feedback to the user (or viewer) based on the vibration of the display panel or the vibrating member 100.

[0079] The vibration device 200 according to embodiments of this disclosure can be implemented as a diaphragm. Since the vibration device 200 is implemented as a diaphragm, it can have a thinner thickness than the vibrating member 100, thereby minimizing the increase in device thickness caused by the arrangement of the vibration device 200. For example, the vibration device 200 may be referred to as a sound generating module using a display panel or vibrating member 100 as a vibrating plate or sound vibrating plate, a sound generating device, a vibration generating device, a displacement device, a sound device, a diaphragm actuator, a diaphragm piezoelectric composite actuator, a diaphragm loudspeaker, a diaphragm piezoelectric loudspeaker, or a diaphragm piezoelectric composite loudspeaker, but the terminology is not limited thereto.

[0080] According to another embodiment of this disclosure, the vibration device 200 may not be disposed on the rear surface of the vibration member 100, and may be applied to a non-display panel instead of a display panel. For example, the non-display panel may be one or more of the following: wood, plastic, glass, metal, cloth, fiber, rubber, paper, leather, vehicle interior materials, building interior ceilings, aircraft interior materials, but embodiments of this disclosure are not limited thereto. In this case, the non-display panel can be used as a vibrating plate, and the vibration device 200 can cause the non-display panel to vibrate to output sound.

[0081] For example, an apparatus according to an embodiment of this disclosure may include a vibrating member (or vibrating object) 100 and a vibrating device 200 disposed in the vibrating member 100. For example, the vibrating member 100 may include a display panel containing pixels for displaying images, or it may include a non-display panel. For example, the vibrating member 100 may include a display panel containing pixels for displaying images, or it may be one or more of the following: wood, plastic, glass, metal, cloth, fiber, rubber, paper, leather, mirror, vehicle interior material, vehicle window, building interior ceiling, building window, building interior material, aircraft interior material, and aircraft window, but the embodiments of this disclosure are not limited thereto.

For example, the non-display panel may be a light-emitting diode (LED) lighting panel (or device), an organic light-emitting diode (OLED) lighting panel (or device), or an inorganic light-emitting diode (LED) lighting panel (or device), but the embodiments of this disclosure are not limited thereto. For example, the vibrating member 100 may include a display panel containing pixels for displaying images, or may be one or more of the following: a light-emitting diode (LED) lighting panel (or device), an organic light-emitting diode (OLED) lighting panel (or device), and an inorganic light-emitting diode (LED) lighting panel (or device), but the embodiments of this disclosure are not limited thereto.

[0082] According to another embodiment of this disclosure, the vibrating member 100 may include a plate. The plate may comprise a metallic material, or it may comprise a single non-metallic material or a composite non-metallic material, including one or more of the following: wood, plastic, glass, cloth, fiber, rubber, paper, mirror, and leather, but the embodiments of this disclosure are not limited thereto. For example, the paper may be tapered paper for a loudspeaker. For example, the tapered paper may be pulp or foam plastic, but the embodiments of this disclosure are not limited thereto. For example, the vibrating member 100 may be a vibrating object, a vibrating plate, or a front member, but the embodiments of this disclosure are not limited thereto.

[0083] According to an embodiment of the present disclosure, the vibration device 200 can be disposed on the rear surface of the vibration member 100 to overlap with the display area (or active area) AA of the vibration member 100. For example, the vibration device 200 can overlap with half or more of the display area AA of the vibration member 100. According to another embodiment of the present disclosure, the vibration device 200 can overlap with the entire display area AA of the vibration member 100.

[0084] When an alternating current (AC) voltage is applied, the vibration device 200 according to embodiments of the present disclosure can alternately contract and expand based on the inverse piezoelectric effect, and can vibrate the vibration member 100 based on vibration. According to embodiments of the present disclosure, the vibration device 200 can vibrate the display panel 100 based on a voice signal synchronized with an image displayed on the display panel. According to another embodiment of the present disclosure, the vibration device 200 can vibrate based on a tactile feedback signal (or haptic feedback signal) synchronized with a user touch applied to a touch panel (or touch sensor layer) disposed on or embedded in the vibration member 100, and thus can vibrate the vibration member 100. Therefore, the vibration member 100 can vibrate based on the vibration of the vibration device 200 to provide one or more of sound and tactile feedback to the user (or viewer).

[0085] Therefore, the apparatus according to embodiments of the present disclosure can output sound generated by the vibration of the vibrating member 100 in the forward direction of the vibrating member 100 based on the vibration of the vibrating device 200. Furthermore, the apparatus for generating vibration according to embodiments of the present disclosure can further enhance the sound localization and sound pressure level characteristics based on the vibration of the vibrating member 100 by using a diaphragm-type vibrating device 200 to vibrate a large area of ​​the vibrating member 100.

[0086] According to embodiments of this disclosure, the rear surface (or rear side surface) of the vibrating member 100 may include a first region (or first rear region) A1 and a second region (or second rear region) A2. For example, on the rear surface of the vibrating member 100, the first region A1 may be a left rear region, and the second region A2 may be a right rear region. For a first direction X, the first region A1 and the second region A2 may be horizontally symmetrical with respect to the centerline CL of the vibrating member 100, but embodiments of this disclosure are not limited thereto. For example, each of the first region A1 and the second region A2 may overlap with the display area AA of the vibrating member 100.

[0087] The vibration device 200 according to the embodiments of the present disclosure may include a first vibration device 200-1 and a second vibration device 200-2 disposed on the rear surface of the vibration member 100.

[0088] A first vibration device 200-1 may be disposed in a first region A1 of the vibration member 100. For example, the first vibration device 200-1 may be disposed near the center portion or edge of the first region A1 of the vibration member 100 relative to a first direction X. According to embodiments of the present disclosure, the first vibration device 200-1 can cause the first region A1 of the vibration member 100 to vibrate, and thus can generate a first vibrational sound or a first tactile feedback in the first region A1 of the vibration member 100. For example, according to embodiments of the present disclosure, the first vibration device 200-1 can directly cause the first region A1 of the vibration member 100 to vibrate, and thus can generate a first vibrational sound or a first tactile feedback in the first region A1 of the vibration member 100. For example, the first vibrational sound may be a left-handed sound. Based on the characteristics of the first vibrational sound or the desired sound characteristics of the device, the size of the first vibration device 200-1 according to embodiments of the present disclosure may be half or less than the size of the first region A1, or may be half or more of the size of the first region A1. In another embodiment according to the present disclosure, the size of the first vibration device 200-1 may be a size corresponding to the first region A1 of the vibration member 100. For example, the size of the first vibration device 200-1 can be less than or equal to the size of the first region A1 of the vibration member 100.

[0089] The second vibration device 200-2 may be disposed in the second region A2 of the vibration member 100. For example, the second vibration device 200-2 may be disposed near the center portion or edge of the second region A2 of the vibration member 100 relative to the first direction X. According to embodiments of the present disclosure, the second vibration device 200-2 can cause the second region A2 of the vibration member 100 to vibrate, and thus generate a second vibration sound or a second tactile feedback in the second region A2 of the vibration member 100. For example, according to embodiments of the present disclosure, the second vibration device 200-2 can directly cause the second region A2 of the vibration member 100 to vibrate, and thus generate a second vibration sound or a second tactile feedback in the second region A2 of the vibration member 100. For example, the second vibration sound may be a right-handed sound. Based on the characteristics of the second vibration sound or the desired sound characteristics of the device, the size of the second vibration device 200-2 according to embodiments of the present disclosure may be half or less than the size of the second region A2, or may be half or more of the size of the second region A2. In another embodiment of the present disclosure, the size of the second vibration device 200-2 may be a size corresponding to the second region A2 of the vibration member 100 or the display panel. For example, the size of the second vibration device 200-2 can be less than or equal to the size of the second region A2 of the vibration member 100. Therefore, based on the left-right sound characteristics and / or the overall sound characteristics of the device 10, the first vibration device 200-1 and the second vibration device 200-2 can have the same size or different sizes. Furthermore, the first vibration device 200-1 and the second vibration device 200-2 can be arranged in a left-right symmetrical or left-right asymmetrical structure relative to the center line CL of the vibration member 100.

[0090] Each of the first vibration device 200-1 and the second vibration device 200-2 may include a piezoelectric structural material (vibrating part or piezoelectric vibrating part), which includes a piezoelectric ceramic having piezoelectric properties, but the embodiments of this disclosure are not limited thereto. For example, each of the first vibration device 200-1 and the second vibration device 200-2 according to the embodiments of this disclosure may include a piezoelectric ceramic having a perovskite crystal structure, and therefore may vibrate (or mechanically displace) in response to an externally applied electrical signal. For example, when a vibration drive signal (or voice signal) is applied, each of the first vibration device 200-1 and the second vibration device 200-2 may alternately and repeatedly contract and expand based on the inverse piezoelectric effect of the piezoelectric structural material (vibrating part or piezoelectric vibrating part), and therefore may displace (or vibrate) in the same direction based on the bending phenomenon of alternating bending directions, thereby increasing or maximizing the displacement (or bending force) or amplitude displacement of the vibration device 200 and / or the vibration member 100.

[0091] The vibrations generated by each of the first vibration device 200-1 and the second vibration device 200-2 can cause the entire first region (or first rear region) A1 and the second region (or second rear region) A2 to vibrate, thereby improving user satisfaction and increasing the sound localization. Furthermore, the contact area (or panel coverage) between the vibrating member 100 and each of the first vibration device 200-1 and the second vibration device 200-2 can be increased, and thus the vibration area of ​​the vibrating member 100 can be increased, thereby enhancing the mid-to-low frequency sound generated based on the vibration of the vibrating member 100. Moreover, the vibration device 200 applied to a large device can cause the entire vibrating of the vibrating member 100, which has a large size (or large area), and thus can further enhance the sound localization based on the vibration of the vibrating member 100, thereby achieving an enhanced sound effect. Therefore, the vibration device 200 according to the embodiments of this disclosure can be disposed on the rear surface of the vibrating member 100 so that the vibrating member 100 vibrates sufficiently in the vertical (or forward or backward) direction, thereby outputting the desired sound in the forward direction of the display device or device. For example, the vibration device 200 can be disposed on the rear surface of the vibration member 100 so that the vibration member 100 vibrates sufficiently in the vertical (forward or backward) direction relative to the first direction X, thereby outputting the desired sound in the forward direction of the display device or the device.

[0093] For example, the connecting member 250 may be disposed between the vibration device 200 and the rear surface of the vibration member 100 or the display panel, and thus the vibration device 200 may be connected or coupled to the rear surface of the vibration member 100. For example, the vibration device 200 may be connected or coupled to the rear surface of the vibration member 100 or the display panel using the connecting member 250, and thus may be supported by or disposed on the rear surface of the vibration member 100 or the display panel.

[0095] The adhesive layer of the connecting member 250 may also include additives such as tackifiers, wax components, or antioxidants, but embodiments of this disclosure are not limited thereto. Additives can prevent the connecting member 250 from detaching (peeling off) from the vibrating member 100 due to vibration of the vibrating device 200. For example, the tackifier may be a rosin derivative, the wax component may be paraffin wax, and the antioxidant may be a phenolic antioxidant such as a thiolesterol ester, but embodiments of this disclosure are not limited thereto.

The hollow portion of the connecting member 250 may provide an air gap between the vibrating device 200 and the vibrating member 100 or the display panel. Based on this air gap, the sound waves (or sound pressure level) generated by the vibration of the vibrating device 200 may not be dispersed by the connecting member 250 but may be concentrated on the vibrating member 100 or the display panel, and thus vibration loss based on the connecting member 250 may be minimized, thereby increasing the sound pressure level characteristics and / or sound characteristics of the sound generated by the vibration of the vibrating member 100.

[0097] The device 10 for generating vibration according to embodiments of the present disclosure may further include a support member 300 disposed on the rear surface (or rear side surface) of the vibration member 100.

[0113] Figure 3 This is a perspective view showing a vibration device according to an embodiment of the present disclosure, and Figure 4 It is along Figure 3 The cross-sectional view taken by line B-B'.

[0114] Reference Figure 3 and Figure 4 The vibration device 200 according to the embodiments of this disclosure may be referred to as a flexible vibration structure material, a flexible vibrator, a flexible vibration generating device, a flexible vibration generator, a flexible sound generator, a flexible sound device, a flexible sound generating device, a flexible sound generator, a flexible actuator, a flexible loudspeaker, a flexible piezoelectric loudspeaker, a membrane actuator, a membrane piezoelectric composite actuator, a membrane loudspeaker, a membrane piezoelectric loudspeaker, or a membrane piezoelectric composite loudspeaker, but the terminology is not limited thereto.

[0115] The vibrating part 210a may include a piezoelectric material. For example, the vibrating part 210a may include a piezoelectric material (or an electroactive material) having a piezoelectric effect. For example, the piezoelectric material may have the following characteristics: when pressure or torsion is applied to the crystal structure by an external force, a potential difference is generated due to dielectric polarization caused by the change in the relative positions of positive (+) ions and negative (-) ions, and vibration is generated by an electric field based on the voltage applied thereto. The vibrating part 210a may be referred to by terms such as vibrating layer, piezoelectric layer, piezoelectric material layer, electroactive layer, vibrating part, piezoelectric material part, electroactive part, piezoelectric structural material, piezoelectric composite layer, piezoelectric composite, or piezoelectric ceramic composite, but the terminology is not limited thereto. The vibrating part 210a may include a transparent conductive material, a semi-transparent conductive material, or an opaque conductive material, and may be transparent, semi-transparent, or opaque.

[0116] The vibrating part 210a according to embodiments of this disclosure may include a ceramic-based material for generating relatively high vibrations, or may include a piezoelectric ceramic having a perovskite-based crystal structure. The perovskite crystal structure may have a piezoelectric effect and / or an inverse piezoelectric effect, and may be an oriented plate-like structure. The perovskite crystal structure may be represented by the chemical formula "ABO3". In the chemical formula, "A" may include a divalent metal element, and "B" may include a tetravalent metal element. For example, in the chemical formula "ABO3", "A" and "B" may be cations, and "O" may be an anion. For example, the vibrating part 210a may contain one or more of lead(II) titanate (PbTiO3), lead zirconate (PbZrO3), lead zirconate titanate (PbZrTiO3), barium titanate (BaTiO3), and strontium titanate (SrTiO3), but embodiments of this disclosure are not limited thereto.

[0117] In perovskite crystal structures, the polarization can be altered by changing the position of the central ion through external stress or a magnetic field, and a piezoelectric effect can be generated based on this change in polarization. In perovskite crystal structures including PbTiO3, the polarization can be changed by altering the position of the Ti ion corresponding to the central ion, and thus a piezoelectric effect can be generated. For example, in perovskite crystal structures, a cubic shape with a symmetrical structure can be changed into a square, orthorhombic, or rhombohedral shape, each with an asymmetrical structure, by using external stress or a magnetic field, and thus a piezoelectric effect can be generated. The polarization can be high at the isomorphic phase boundaries (MPBs) of the square and rhombohedral structures, and the polarization can be easily realigned, resulting in high piezoelectric properties.

[0118] According to embodiments of the present disclosure, the vibrating part 210a may include one or more materials selected from lead (Pb), zirconium (Zr), titanium (Ti), zinc (Zn), nickel (Ni) and niobium (Nb), but the embodiments of the present disclosure are not limited thereto.

According to another embodiment of this disclosure, the vibrating part 210a may include one or more of calcium titanate (CaTiO3), BaTiO3, and SrTiO3, none of which contain Pb, but the embodiments of this disclosure are not limited thereto.

[0121] According to another embodiment of this disclosure, the vibrating part 210a may have a piezoelectric deformation coefficient "d" of 1,000 pC / N or greater in the thickness direction Z. 33 "Through the high piezoelectric deformation coefficient "d 33 This can provide vibration devices that can be applied to display panels or vibrating components (or vibrating objects) with large sizes, or that possess sufficient vibrational or piezoelectric properties. For example, to achieve a high piezoelectric deformation coefficient "d 33 The inorganic material portion may include PZT-based materials (PbZrTiO3) as the main component, and may include softening agent dopant materials doped to the A site (Pb) and relaxor ferroelectric materials doped to the B site (ZrTi).

[0122] Softener dopant materials can enhance the piezoelectric and dielectric properties of the vibrating part 210a. For example, softener dopant materials can increase the piezoelectric deformation coefficient "d" of the inorganic material portion. 33 The softener dopant material according to embodiments of this disclosure may include divalent elements "+2" to trivalent elements "+3". Quasi-isomorphic phase boundaries (MPBs) can be achieved by adding softener dopant materials to PZT-based materials (PbZrTiO3), and thus piezoelectric and dielectric properties can be enhanced. For example, softener dopant materials may include strontium (Sr), barium (Ba), lanthanum (La), neodymium (Nd), calcium (Ca), yttrium (Y), erbium (Er), or ytterbium (Yb). For example, ions of softener dopant materials doped into PZT-based materials (PbZrTiO3) (e.g., Sr...) 2+ Ba 2+ La 2+ 、Nd 3+ Ca 2+ Y 3+ Er 3+ and Yb 3+This material can replace the lead (Pb) portion of PZT-based materials (PbZrTiO3), and the substitution rate can be from about 2 mol% to about 20 mol%. For example, when the substitution rate is less than 2 mol% or greater than 20 mol%, the perovskite crystal structure may be disrupted, and thus the electromechanical coupling coefficient "kP" and the piezoelectric deformation coefficient "d" may be reduced. 33 When the softener dopant is replaced, an MPB can be formed, and the piezoelectric and dielectric properties of the MPB can be high, thereby realizing a vibration device with high piezoelectric and high dielectric properties.

[0123] According to embodiments of this disclosure, relaxor ferroelectric materials doped into PZT-based materials (PbZrTiO3) can enhance the electrical deformation properties of the inorganic material portion. The relaxor ferroelectric materials according to embodiments of this disclosure may include PMN-based materials, PNN-based materials, PZN-based materials, or PIN-based materials, but embodiments of this disclosure are not limited thereto. PMN-based materials may include Pb, Mg, and Nb, and may include, for example, Pb(Mg,Nb)O3. PNN-based materials may include Pb, Ni, and Nb, and may include, for example, Pb(Ni,Nb)O3. PZN-based materials may include Pb, Zr, and Nb, and may include, for example, Pb(Zn,Nb)O3. PIN-based materials may include Pb, In, and Nb, and may include, for example, Pb(In,Nb)O3. For example, relaxor ferroelectric materials doped into PZT-based materials (PbZrTiO3) can replace a portion of each of the zirconium (Zr) and titanium (Ti) in the PZT-based material (PbZrTiO3), and the substitution rate can be from about 5 mol% to about 25 mol%. For example, when the substitution rate is less than 5 mol% or greater than 25 mol%, the perovskite crystal structure may be disrupted, and thus the electromechanical coupling coefficient “kP” and the piezoelectric deformation coefficient “d” may be reduced. 33 ".

[0124] According to embodiments of this disclosure, the vibrating part 210a may further include donor material doped into the B-site (ZrTi) of the PZT-based material (PbZrTiO3) to further improve the piezoelectric coefficient. For example, the donor material doped into the B-site (ZrTi) may include a tetravalent element "+4" or a hexavalent element "+6". For example, the donor material doped into the B-site (ZrTi) may include tellurium (Te), germanium (Ge), uranium (U), bismuth (Bi), niobium (Nb), tantalum (Ta), antimony (Sb), or tungsten (W).

[0125] According to embodiments of this disclosure, the vibrating part 210a may have a piezoelectric deformation coefficient "d" of 1,000 pC / N or greater in the thickness direction Z. 33 Therefore, a vibration device 200 with enhanced vibration characteristics can be realized. For example, a vibration device 200 with enhanced vibration characteristics can be realized in a device or vibrating object with a large area.

The opaque conductive material may include aluminum (Al), copper (Cu), gold (Au), silver (Ag), molybdenum (Mo), or magnesium (Mg) or alloys thereof, but embodiments of this disclosure are not limited thereto.

[0128] The second electrode portion 210c can be disposed on the second surface (or rear surface or rear side surface) of the vibrating portion 210a opposite to the first surface, and can be electrically connected to the second surface of the vibrating portion 210a. For example, the second electrode portion 210c can have a common electrode form disposed on the entire second surface of the vibrating portion 210a. According to embodiments of the present disclosure, the second electrode portion 210c can include a transparent conductive material, a semi-transparent conductive material, or an opaque conductive material.

For example, the first cover member 240 may cover the first electrode portion 210b disposed on the first surface of the vibration portion 210a, and thus may protect the first surface of the vibration portion 210a or the first electrode portion 210b.

[0131] The second cover member 260 may be provided on the second surface of the vibration device 200. For example, the second cover member 260 may be provided at the second electrode portion 210c. For example, the second cover member 260 may be on the second electrode portion 210c. For example, the second cover member 260 may cover the second electrode portion 210c provided on the second surface of the vibration portion 210a, and thus protect the second surface of the vibration portion 210a or the second electrode portion 210c.

[0132] Each of the first cover member 240 and the second cover member 260 according to embodiments of this disclosure may include one or more materials selected from plastic, fiber, and wood, but embodiments of this disclosure are not limited thereto. For example, the first cover member 240 and the second cover member 260 may include the same material or different materials. For example, the first cover member 240 and the second cover member 260 may be a polyimide film or a polyethylene terephthalate film, but embodiments of this disclosure are not limited thereto.

[0133] According to another embodiment of this disclosure, the vibration device 200 may further include a first adhesive layer 220 and a second adhesive layer 230. For example, the first adhesive layer 220 may be disposed between the first cover member 240 and the first electrode portion 210b. For example, the second adhesive layer 230 may be disposed between the second cover member 260 and the second electrode portion 210c.

[0134] According to embodiments of this disclosure, the first cover member 240 can be disposed on the first surface of the vibrating portion 210a using a first adhesive layer 220. For example, the first cover member 240 can be connected or coupled to the first electrode portion 210b using the first adhesive layer 220. For example, the first cover member 240 can be disposed on the first surface of the vibrating portion 210a using a film lamination process with the first adhesive layer 220. Therefore, the vibrating portion 210a can be provided (or disposed) integrally with the first cover member 240.

[0135] According to embodiments of this disclosure, the second cover member 260 can be disposed on the second surface of the vibrating portion 210a using a second adhesive layer 230. For example, the second cover member 260 can be connected or coupled to the second electrode portion 210c using the second adhesive layer 230. For example, the second cover member 260 can be disposed on the second surface of the vibrating portion 210a using a film lamination process with the second adhesive layer 230. Therefore, the vibrating portion 210a can be provided (or disposed) integrally with the second cover member 260.

[0136] For example, the first adhesive layer 220 and the second adhesive layer 230 can completely surround the vibration device 200. For example, the first adhesive layer 220 and the second adhesive layer 230 can be disposed between the first cover member 240 and the second cover member 260 to surround the vibration portion 210a, the first electrode portion 210b, and the second electrode portion 210c. For example, the first adhesive layer 220 and the second adhesive layer 230 can be disposed between the first cover member 240 and the second cover member 260 to completely surround the vibration portion 210a, the first electrode portion 210b, and the second electrode portion 210c. For example, the vibration portion 210a, the first electrode portion 210b, and the second electrode portion 210c can be embedded or recessed between the first adhesive layer 220 and the second adhesive layer 230. For ease of description, the first adhesive layer 220 and the second adhesive layer 230 are shown as a first adhesive layer 220 and a second adhesive layer 230, but are not limited thereto and can be configured as a single adhesive layer.

[0137] Each of the first adhesive layer 220 and the second adhesive layer 230 according to embodiments of this disclosure may include an electrically insulating material having adhesive properties and capable of compression and decompression. For example, each of the first adhesive layer 220 and the second adhesive layer 230 may include epoxy resin, acrylic resin, silicone resin, or polyurethane resin, but embodiments of this disclosure are not limited thereto.

[0138] The audio controller can generate an AC vibration drive signal, including a first vibration drive signal and a second vibration drive signal, based on a sound source. The first vibration drive signal can be either a positive (+) vibration drive signal or a negative (-) vibration drive signal, and the second vibration drive signal can also be either a positive (+) vibration drive signal or a negative (-) vibration drive signal. For example, the first vibration drive signal can be supplied to the first electrode portion 210b of the vibration device 200 via the terminals of the signal cable 219, the pad electrodes of the pad portion, and the first power line. The second vibration drive signal can be supplied to the second electrode portion 210c of the vibration device 200 via the terminals of the signal cable, the pad electrodes of the pad portion, and the second power line.

[0139] According to embodiments of the present disclosure, the vibration unit 210a can be integrally constructed by the first cover member 240 and the second cover member 260, thereby providing a vibration device with a simplified structure and thin thickness.

[0140] One or more first power lines PL1 in the vibration device 200 may extend relatively long along the second direction Y. The first power lines PL1 may be disposed at the first cover member 240 and electrically connected to the first electrode portion 210b. For example, the first power line PL1 may be disposed on the rear surface of the first cover member 240 facing the first electrode portion 210b and electrically connected to the first electrode portion 210b. Alternatively, the first power line PL1 may be disposed on the rear surface of the first cover member 240 directly facing the first electrode portion 210b and directly electrically connected to the first electrode portion 210b. For example, the first power line PL1 may be electrically connected to the first electrode portion 210b by using an anisotropic conductive film. As another example, the first power line PL1 may be electrically connected to the first electrode portion 210b by a conductive material (or particles) included in the first adhesive layer 212.

[0141] For example, one or more first power lines PL1 in the vibration device 200 may include one or more first power lines protruding along a first direction X intersecting the second direction Y. One or more first power lines may extend a considerable distance along the first direction X from one or more surfaces of the first power line PL1 and may be electrically connected to the first electrode portion 210b. Therefore, one or more first power lines can enhance the uniformity of the vibration drive signal applied to the first electrode portion 210b.

[0142] The pad portion 217 may be electrically connected to a first portion (or one side or one end) of one or more of the first power line PL1 and the second power line PL2. For example, the pad portion 217 may be provided at the edge portion of one or more of the first cover member 240 and the second cover member 260.

[0143] The pad portion 217 according to the embodiment may include a first pad electrode and a second pad electrode, the first pad electrode being electrically connected to a first portion (or one side or one end) of a first power line PL1, and the second pad electrode being connected to a first portion (or one side or one end) of a second power line PL2. For example, one or more of the first pad electrode and the second pad electrode may be exposed at a first edge portion of one or more of the first cover member 240 and the second cover member 260.

[0144] Figure 5A and 5B This is a perspective view of the vibrating section according to an embodiment of the present disclosure.

[0145] Reference Figure 5A and Figure 5B The vibration device according to the embodiments of this disclosure may be referred to as a flexible vibration structure material, a flexible vibrator, a flexible vibration generating device, a flexible vibration generator, a flexible sound generator, a flexible sound device, a flexible sound generating device, a flexible sound generator, a flexible actuator, a flexible loudspeaker, a flexible piezoelectric loudspeaker, a membrane actuator, a membrane piezoelectric composite actuator, a membrane loudspeaker, a membrane piezoelectric loudspeaker, or a membrane piezoelectric composite loudspeaker, but the terminology is not limited thereto.

[0146] The vibration section 210a according to embodiments of the present disclosure may include a plurality of first portions 210a1 and a plurality of second portions 210a2. For example, the plurality of first portions 210a1 and the plurality of second portions 210a2 may be arranged alternately and repeatedly along a first direction X (or a second direction Y). For example, the first direction X may be the width direction of the vibration section 210a, and the second direction Y may be the length direction of the vibration section 210a intersecting the first direction X. However, embodiments of the present disclosure are not limited to this, and the first direction X may be the length direction of the vibration section 210a, and the second direction Y may be the width direction of the vibration section 210a.

[0147] For example, the first part 210a1 may contain an inorganic material, while the second part 210a2 may contain an organic material. For example, the first part 210a1 may be a piezoelectric material, while the second part 210a2 may have ductile or flexible properties. For example, the inorganic material of the first part 210a1 may be a piezoelectric material, while the organic material of the second part 210a2 may have ductile or flexible properties.

[0148] Each of the plurality of first portions 210a1 may include an inorganic material portion. The inorganic material portion may include a piezoelectric material, a composite piezoelectric material, or an electroactive material having a piezoelectric effect.

[0149] Each of the plurality of first portions 210a1 may comprise a ceramic-based material for generating relatively high vibrations, or may comprise a piezoelectric ceramic having a perovskite-based crystal structure. For example, each of the plurality of first portions 210a1 may comprise one or more of lead(II) titanate (PbTiO3), lead zirconate (PbZrO3), lead zirconate titanate (PbZrTiO3), barium titanate (BaTiO3), and strontium titanate (SrTiO3), but embodiments of this disclosure are not limited thereto.

[0150] Each of the plurality of first portions 210a1 may comprise a lead zirconate titanate (PZT) based material (which includes lead (Pb), zirconium (Zr), and titanium (Ti)); or may comprise a lead nickel zirconate niobate (PZNN) based material (which includes lead (Pb), zirconium (Zr), nickel (Ni), and niobium (Nb)), but embodiments of this disclosure are not limited thereto. According to another embodiment of this disclosure, each of the plurality of first portions 210a1 may comprise one or more of calcium titanate (CaTiO3), BaTiO3, and SrTiO3, none of which contain Pb, but embodiments of this disclosure are not limited thereto.

[0151] Each of the plurality of second portions 210a2 according to embodiments of the present disclosure may include an organic material portion. The organic material portion included in the second portion 210a2 may comprise an organic material, organic polymer, organic piezoelectric material, or organic non-piezoelectric material that has flexible properties compared to the inorganic material portion serving as the first portion 210a1. For example, the second portion 210a2 may be referred to as an adhesive portion, a stretching portion, a bending portion, a damping portion, or a flexible portion having flexibility, but embodiments of the present disclosure are not limited thereto. For example, the organic material portion may be disposed between two adjacent inorganic material portions, and thus may absorb impacts applied to the inorganic material portion (or the first portion) and may release stress concentrated on the inorganic material portion, thereby enhancing the durability of the vibrating part 210a or the vibration device 210 and providing flexibility to the vibrating part 210a or the vibration device 210.

[0152] Reference Figure 5A A plurality of first portions 210a1 and a plurality of second portions 210a2 may be arranged alternately and repeatedly along a first direction X. Each of the plurality of first portions 210a1 may be disposed between the plurality of second portions 210a2. For example, each of the plurality of first portions 210a1 may have a first width W1 parallel to the first direction X and a length parallel to the second direction Y. Each of the plurality of second portions 210a2 may have a second width W2 parallel to the first direction X and a length parallel to the second direction Y. 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 portions 210a1 and the second portions 210a2 may include line shapes or strip shapes having the same size or different sizes. Therefore, Figure 5A The vibrating part 210a shown may have a 2-2 composite structure and may have a resonant frequency of 20 kHz or less, but the embodiments of this disclosure are not limited thereto. For example, the resonant frequency of the vibrating part 210a may vary based on one or more of the shape, length, and thickness of the vibrating part.

[0153] exist Figure 5A In the illustrated vibrating section 210a, a plurality of first portions 210a1 and a plurality of second portions 210a2 can be arranged (or arranged) in parallel on the same plane (or the same layer). Each of the plurality of second portions 210a2 can be configured to fill the gap between two adjacent first portions 210a1, and therefore, each of the plurality of second portions 210a2 can be connected to or attached to an adjacent first portion 210a. Thus, the vibrating section 210a can extend to a desired size or length based on the lateral coupling (or connection) of the first portions 210a1 and the second portions 210a2.

[0154] exist Figure 5A In the vibrating part 210a shown, the width W2 of each of the plurality of second parts 210a2 can gradually decrease along the direction from the center part of the vibrating part 210a or the vibrating device to its two edge parts (or sides or ends).

[0155] According to embodiments of this disclosure, the second portion 210a2 having the largest width W2 among the plurality of second portions 210a2 can be located at the portion where the highest stress may concentrate when the vibrating part 210a or the vibrating device vibrates in the vertical direction Z (or the thickness direction). The second portion 210a2 having the smallest width W2 among the plurality of second portions 210a2 can be located at the portion where relatively low stress may occur when the vibrating part 210a or the vibrating device vibrates in the vertical direction Z. For example, the second portion 210a2 having the largest width W2 among the plurality of second portions 210a2 can be provided at the central portion of the vibrating part 210a, and the second portion 210a2 having the smallest width W2 among the plurality of second portions 210a2 can be provided at each of the two peripheries of the vibrating part 210a. Therefore, when the vibrating part 210a or the vibrating device vibrates in the vertical direction Z, the interference of sound waves or the overlap of resonant frequencies that both occur in the portion where the highest stress concentration occurs can be reduced or minimized. Therefore, the drop in sound pressure level in the low-pitched sound band can be reduced, thereby improving the flatness of the sound characteristics in the low-pitched band. For example, the flatness of sound characteristics can be the level of deviation between the highest and lowest sound pressure levels.

[0156] exist Figure 5AIn the vibrating section 210a shown, the plurality of first portions 210a1 can have different dimensions (or widths) W1. For example, the dimension (or width) of each of the plurality of first portions 210a1 can gradually decrease or increase along the direction from the center portion of the vibrating section 210a or the vibrating device to its two edge portions (or sides or ends). Therefore, based on the vibration of the plurality of first portions 210a1 with different dimensions, the sound pressure level characteristics of the sound of the vibrating section 210a can be enhanced through various unique vibration frequencies, and the sound reproduction frequency band can be extended.

[0157] Each of the plurality of second portions 210a2 can be disposed between the plurality of first portions 210a1. Therefore, in the vibrating section 210a or the vibrating device 210, the vibrational energy of the links in the unit grid based on the first portions 210a1 can be increased by the second portions 210a2, and thus, vibrational characteristics can be improved while piezoelectric properties and flexibility can be guaranteed. For example, the second portions 210a2 may comprise one of epoxy-based polymers, acrylic polymers, and silicone polymers, but embodiments of this disclosure are not limited thereto.

[0158] Each of the plurality of second portions 210a2 according to embodiments of the present disclosure may be configured to have an organic material portion. For example, the organic material portion may be disposed between two adjacent inorganic material portions and thus may absorb impacts applied to the inorganic material portion (or the first portion) and may release stress concentrated on the inorganic material portion, thereby enhancing the durability of the vibrating part 210a or the vibration device 210 and achieving the flexibility of the vibrating part 210a or the vibration device 210.

[0159] The second portion 210a2 according to embodiments of this disclosure may have a lower modulus and viscoelasticity than the first portion 210a1, and therefore, the second portion 210a2 may enhance the reliability of the first portion 210a1, which is susceptible to impact due to the brittle nature of the first portion 210a1. For example, the second portion 210a2 may comprise a material having a loss coefficient of about 0.01 to about 1 and a modulus of about 0.1 [GPa] to about 10 [GPa].

[0160] The organic material portion included in the second part 210a2 may contain organic materials, organic polymers, organic piezoelectric materials, or organic non-piezoelectric materials that have flexible properties compared to the inorganic material portion of the first part 210a1. For example, the second part 210a2 may be referred to as an adhesive portion, a flexible portion, a bending portion, a damping portion, or a ductile portion, etc., but embodiments of the present disclosure are not limited thereto.

[0161] Multiple first portions 210a1 and multiple second portions 210a2 can be disposed on the same plane (or connected to) the same plane, and therefore, the vibrating portion 210a according to this embodiment can have the form of a single thin film. For example, the vibrating portion 210a can have a structure in which multiple first portions 210a1 are connected to one side thereof. For example, the vibrating portion 210a can have a structure in which multiple first portions 210a1 are connected in all vibrating portions 210a. For example, the vibrating portion 210a can vibrate in the vertical direction relative to the display panel or vibrating member by means of the first portions 210a1 having vibration characteristics, and can be bent into a curved shape by means of the flexible second portions 210a2. Furthermore, in the vibrating portion 210a according to this embodiment, the size of the first portion 210a1 and the size of the second portion 210a2 can be set based on the piezoelectric characteristics and flexibility required by the vibrating portion 210a or the vibrating device 210. For example, in a vibrating portion 210a that requires piezoelectric characteristics rather than flexibility, the size of the first portion 210a1 can be set to be larger than the size of the second portion 210a2. In another embodiment of this disclosure, in a vibrating section 210a that requires flexibility rather than piezoelectric properties, the size of the second portion 210a2 can be set to be larger than the size of the first portion 210a1. Therefore, the size of the vibrating section 210a can be adjusted based on the desired characteristics, and thus the vibrating section 210a can be designed easily.

[0162] Reference Figure 5B According to another embodiment of the present disclosure, the vibration part 210a may include a plurality of first parts 210a1 spaced apart from each other in a first direction X and a second part 210a2 disposed between the plurality of first parts.

[0163] A plurality of first portions 210a1 may be arranged spaced apart from each other in each of the first direction X and the second direction Y. For example, the plurality of first portions 210a1 may be arranged in a lattice form to have a hexahedral shape including the same dimensions. Each of the plurality of first portions 210a1 may contain elements as referenced above. Figure 5A The piezoelectric material described in the first part 210a1 is substantially the same as that of the piezoelectric material, and therefore, the same reference numerals refer to the same elements and repeated descriptions thereof are omitted.

[0164] The second portion 210a2 may be arranged between the plurality of first portions 210a1 in each of the first direction X and the second direction Y. The second portion 210a2 may be configured to fill the gap between two adjacent first portions 210a1 or surround each of the plurality of first portions 210a1, and thus may be connected or adhered to adjacent first portions 210a1. According to embodiments of the present disclosure, the width of the second portion 210a2 disposed between two first portions 210a1 adjacent to each other along the first direction X may be the same as or different from the width of the first portions 210a1, and the width of the second portion 210a2 disposed between two first portions 210a1 adjacent to each other along the second direction Y may be the same as or different from the width of the first portions 210a1. The second portion 210a2 may include the same as the portion referred to above. Figure 5A The piezoelectric material described in the second part 210a2 is substantially the same as that of the piezoelectric material, and therefore, the same reference numerals refer to the same elements and repeated descriptions thereof are omitted.

[0165] As described above, the vibrating part 210a according to another embodiment of the present disclosure may have a 1-3 composite structure with piezoelectric characteristics including 1-3 vibration modes, and therefore may have a resonant frequency of 30 MHz or less, but the embodiments of the present disclosure are not limited thereto. For example, the resonant frequency of the vibrating part 210a may vary based on one or more of its shape, length, and thickness.

[0166] According to another embodiment of this disclosure, each of the plurality of first portions 210a1 may have a planar structure including a circular shape. For example, each of the plurality of first portions 210a1 may have a circular plate shape, but the embodiments of this disclosure are not limited thereto. For example, each of the plurality of first portions 210a1 may have a point shape including an elliptical shape, a polygonal shape, or a ring shape.

[0167] According to another embodiment of this disclosure, each of the plurality of first portions 210a1 may have a planar structure including a triangular shape. For example, each of the plurality of first portions 210a1 may have a triangular plate shape.

[0168] Therefore, multiple first portions 210a1 and multiple second portions 210a2 can be disposed on the same plane (or connected to the same plane), and thus, the vibration part 210a according to this embodiment can have the form of a single thin film. For example, the vibration part 210a can have a structure in which multiple first portions 210a1 are connected to one side thereof. For example, the vibration part 210a can have a structure in which multiple first portions 210a1 are connected in all vibration parts 210a. For example, the vibration part 210a can vibrate in the vertical direction relative to the display panel or vibration member by means of the first portions 210a1 having vibration characteristics, and can be bent into a curved shape by means of the flexible second portions 210a2. Furthermore, in the vibration part 210a according to this embodiment, the size of the first portion 210a1 and the size of the second portion 210a2 can be set based on the piezoelectric characteristics and flexibility required by the vibration part 210a or the vibration device 210. For example, in a vibration part 210a that requires piezoelectric characteristics rather than flexibility, the size of the first portion 210a1 can be set to be larger than the size of the second portion 210a2. In another embodiment of this disclosure, in a vibrating section 210a that requires flexibility rather than piezoelectric properties, the size of the second portion 210a2 can be set to be larger than the size of the first portion 210a1. Therefore, the size of the vibrating section 210a can be adjusted based on the desired characteristics, and thus the vibrating section 210a can be designed easily.

Each flexible data circuit film 110 can be attached to a corresponding pad of the pad portion PP provided in the display panel 100 by a film attachment process using conductive anisotropic films. Here, the film attachment process can use tape-on-board (TAB) technology.

[0173] Each pad (PP) can be located in the upper non-display area adjacent to one end of each of the multiple data lines, and can be electrically connected to one end of the multiple data lines.

[0174] According to embodiments of this disclosure, the display panel 100 may further include a gate driver disposed in a non-display area 1A of the display panel 100, and the gate driver may be configured as a gate embedded circuit. The gate driver may be electrically connected to one end of each of a plurality of gate lines.

[0175] Each of the data driver ICs 120 can be mounted on a corresponding flexible data circuit film 110. Each data driver IC 120 can be connected to data lines, pixel drive power lines, and sensor lines via the corresponding flexible data circuit film 110 and corresponding pad portion PP.

[0176] Each data driver IC 120 according to embodiments of this disclosure can supply a data voltage Vdata and a reference voltage Vref to each pixel, sense the threshold voltage and mobility characteristic changes of the driving transistor Tdr included in each pixel via a sensing line, and output the sensed value of the driving transistor Tdr to the outside.

[0186] Reference Figures 7A to 7C According to embodiments of the present disclosure, the support member 300 may include: a vibration signal cable 360, a portion of which is mounted on a first surface or front surface of the support member 300; a support member opening 370 formed in at least a portion of the support member 300; a control board 150 disposed on a second surface or rear surface of the support member 300; and an audio controller 170, a power board 190, and a voltage generator 191 mounted on the control board 150.

[0187] The vibration signal cable 360 ​​can be configured to connect from the first surface of the support member 300 to its second surface through the support member opening 370. A portion of the vibration signal cable 360 ​​can be disposed on the first surface or front surface of the support member 300, and another portion of the vibration signal cable 360 ​​can be mounted on the second surface or rear surface of the support member 300 and can be disposed in the support member opening 370.

[0188] The support member opening 370 can be formed to pass through the first and second surfaces of the support member 300. The location of the support member opening 370 is not limited to this, and the support member opening 370 can be formed at any desired location, such as the location of the control panel 150 of the display device. For example, the support member opening 370 can be formed adjacent to the audio controller 170, as shown below. Figure 10A The opening 370 of the support member can be formed at a position adjacent to the vibration generating device.

[0189] According to an embodiment of the present disclosure, one end of the vibration signal cable 360 ​​can be connected to an audio controller 170 on the rear surface of the support member 300, and the other end of the vibration signal cable 360 ​​can be disposed on the front surface of the support member 300 and can be electrically connected to the vibration device 200 by using the conductive connection member 500 described below.

[0190] The audio controller 170 can supply AC voltage or AC signal and audio signal from the timing controller 160 to the vibration device 200 via the vibration signal cable 360 ​​during the drive cycle or vibration generation cycle of the vibration device 200. The AC signal can be a vibration drive signal, a sound drive signal, or a tactile drive signal of the vibration device 200. Alternatively, the audio controller 170 can be driven independently of the timing controller 160 and can be controlled to supply audio signals from a separate sound processing circuit. When the operation of the audio controller 170 is controlled by the timing controller 160, a structure can be implemented where the sound processing circuit is mounted on or integrated into the timing controller 160. Here, the audio controller 170 may be referred to as an audio circuit, an audio amplifier circuit, an audio amplifier, or an audio amplifier unit, but the terminology is not limited thereto.

[0191] For example, the audio controller 170 can amplify and output each of the positive and negative audio signals, as well as each of the positive and negative vibration drive signals, based on a predetermined gain value or a gain value adjusted by the timing controller 160.

[0192] Voltage generator 191 can be mounted on power board 190 and can generate and output various voltages based on the input power supplied to voltage generator 191 for displaying images on each pixel of display panel 100 and for driving timing controller 160, data driver IC 120 and gate driver. Furthermore, voltage generator 191 can supply DC voltage to audio controller 170. Power board 190 can be connected to control board 150 via signal cable 180.

[0193] The support member conduit 390 can be formed to pass through the first and second surfaces, and can be formed on the rear surface of the display panel 100 at a position corresponding to or overlapping with the vibration device 200. The support member conduit 390 allows the air layer driven by the vibration device 200 or disposed between the display panel 100 and the support member 300 to flow smoothly, and can generate sound resonance and echo through the support member conduit 390 and the air layer between the display panel 100 and the support member 300, thereby enhancing the sound characteristics (e.g., low-frequency sound characteristics) of the vibration device 200.

[0194] For reference Figure 6 and Figures 7A to 7CAccording to the description, in the structure of the display device in which the display panel 100 is coupled to the support member 300, the other end of the vibration signal cable 360 ​​disposed on the front surface of the support member 300 may be configured to overlap with at least a portion of the vibration device 200, and for example, the other end of the vibration signal cable 360 ​​disposed on the front surface of the support member 300 may be configured to overlap with at least a portion of each of the first power line PL1 and the second power line PL2 of the vibration generating device 200 described below, or the pad portion of the vibration generating device 200.
