Description

Technical Field

[0001] This disclosure relates to an apparatus, and in particular, for example, but not limited to, a display device and a vehicle display device that include a vibrating element. Background Technology

[0002] Recently, haptic technology has been developed to provide haptic or tactile feedback corresponding to the touch input when a user touches the screen of a display device. Display devices using haptic technology stimulate the tango-receptors in the human body, thereby enhancing the user's sense of touch and enabling them to perceive the texture of the touch.

[0003] Haptic feedback (also known as force haptic feedback or pure haptic feedback) provides users with more vivid feedback using a touch interface when applying haptic feedback. Haptic feedback is a technology that allows users to experience touch, force, and motion through input devices such as keyboards, mice, joysticks, and touchscreen panels. In particular, technologies related to haptic feedback that utilize the sense of touch felt through the skin are being applied to portable electronic devices such as smartphones, e-notebooks, e-readers, portable multimedia players (PMPs), navigation systems, mobile phones, tablet PCs (personal computers), smartwatches, watch phones, wearable devices, and game consoles. Additionally, displays incorporating haptic technology can be used, for example, as displays in vehicles such as automobiles.

[0004] Vibrating elements or actuators can be used for tactile feedback.

[0005] The descriptions provided in the background section should not be construed as prior art simply because they are mentioned in or associated with that section.

[0045] The advantages and features of this disclosure, as well as the methods for implementing them, will become clearer with reference to the detailed description of the embodiments described below and the accompanying drawings. However, this disclosure is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided only to ensure the completeness of this disclosure and to inform those skilled in the art of the invention.

[0046] The shapes, sizes, proportions, angles, quantities, etc., disclosed in the accompanying drawings used to explain the embodiments of this disclosure are merely illustrative, and this disclosure is not limited to the details depicted in the drawings. Throughout the specification, the same components may be represented by the same reference numerals. Furthermore, in describing this disclosure, detailed descriptions of related known technologies will be omitted if they are deemed unnecessarily obscuring the spirit of this disclosure.

[0047] In one embodiment of this disclosure, where the terms "comprising," "having," and "constituting of" are used, other parts may be added unless the expression "only" is used. When a component is represented in the singular, the plural is included unless otherwise expressly stated.

[0048] When explaining a component, it is interpreted as including a range of tolerances, even if there is no separate explicit description.

[0049] When describing positional relationships, such as when the positional relationship between two parts is described as "on top", "above", "below", "next to", etc., one or more other parts may be located between the two parts unless the expressions "exactly" or "directly" are used.

[0050] As illustrated in the accompanying drawings, spatially relative terms such as “below,” “below,” “lower,” “above,” and “upper” can be used to readily describe the relationship between one element or component and another. In addition to the orientations depicted in the drawings, spatially relative terms should be understood to include different orientations of elements during use or operation. For example, if an element depicted in the drawings is flipped, an element described as “below” or “below” another element may end up being placed “above” another element. Thus, the exemplary term “below” can encompass both above and below directions. Similarly, the exemplary terms “above” or “upper” can encompass both above and below directions.

[0051] When describing temporal relationships, such as "after", "following", "next", "before", etc., it can also include discontinuous cases as long as the expressions "immediately" or "directly" are not used.

[0052] Although terms such as "first" and "second" are used to describe various components, these components are not limited by these terms. These terms are only used to distinguish one component from another. Therefore, within the scope of this disclosure, the "first" component mentioned below can also be the "second" component.

[0053] At least one term should be understood to include all possible combinations of one or more related items. For example, "at least one of the first, second, and third items" can mean not only the first, second, or third item, but also any combination of items that can be represented by two or more of the first, second, and third items.

[0054] Features of each of the various embodiments of this disclosure may be combined in part or in whole, and various technical connections and operations are possible, and each embodiment may be implemented independently of each other or together in a related relationship.

[0055] Any implementation described as an "example" in this document is not necessarily to be construed as preferred or superior to other implementations.

[0056] Furthermore, when a component or layer is “connected,” “joined,” or “adhered” to another component or layer, unless otherwise stated, the component or layer may not only be directly connected or adhered to the other component or layer, but also indirectly connected or adhered to the other component or layer, with one or more intermediate components or layers “set” or “intercalated” between the components or layers. This should be understood to mean that components may be arranged to be in direct contact with each other, or may be arranged to be in direct contact with each other.

[0057] The terms “first element,” “second element,” and / or “third element” should be understood as one of the first, second, and third elements, or any or all combinations of the first, second, and third elements. For example, A, B, and / or C can refer to only A; only B; only C; any or some combinations of A, B, and C; or all of A, B, and C.

[0058] 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, “at least one of the first element, the second element, and the third element” means a combination of all three listed elements, a combination of any two of the three elements, and each individual element, the first element, the second element, or the third element.

[0059] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which the example embodiments pertain. It should also be understood that terms (such as those defined in common dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant field and should not be interpreted in an idealized or overly formal sense unless explicitly defined herein. For example, the terms “part” or “unit” can be applied to, for example, a single circuit or structure, an integrated circuit, a computational block of a circuit arrangement, or any structure configured to perform the functions described herein that would be understood by one of ordinary skill in the art.

[0060] A display device according to one embodiment of this disclosure may refer to a display module including a display panel and a driving unit for driving the display panel. The display module may include a liquid crystal display module and a light-emitting display module, such as an organic light-emitting display module. Furthermore, the display device may also be referred to as a complete product or end product including a display module, such as a laptop computer, television, computer monitor; equipment for automobiles or other types of vehicles; or a complete set of electronic devices, assemblies, or equipment, such as a mobile electronic device including a smartphone or electronic board.

[0061] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. For ease of explanation, the scale of the components depicted in the drawings may differ from the actual scale. Therefore, the actual components are not limited to the scale depicted in the drawings.

[0062] Figure 1 This is a schematic perspective view of a display device 100 according to one embodiment of the present disclosure, and Figure 2 It is along Figure 1 The cross-sectional view taken from line I-I' and the schematic diagram of touch driving circuit 601.

[0063] A display device 100 according to one embodiment of the present disclosure includes a display panel 110, a touch unit 120, a cover substrate 130, a light-shielding layer 210, a protective film 410, and a vibration element 510. The display device 100 may also include a first adhesive layer 310 or a second adhesive layer 320.

[0064] The cover substrate 130 is the frontmost structure of the display device 100, which can protect the display panel 110 and the touch unit 120 from external impacts.

[0065] The cover substrate 130 may be made of transparent plastic, glass, or tempered glass, but is not limited to these. For example, the cover substrate 130 may be referred to as a front structure, front window, cover window, glass window, cover screen, screen cover, or window glass.

[0066] The cover substrate 130 may include a transmissive region TA and a blocking region BA. The transmissive region TA is the region that allows light to pass through. The blocking region BA is the region that blocks light. By providing a light-shielding layer 210 on the blocking region BA, the blocking region BA can block light. The transmissive region TA may be defined as the region surrounded by the blocking region BA.

[0067] Display panel 110 displays an image. Display panel 110 may include a plurality of pixels configured to display an image. Display panel 110 may include at least one of, for example, an organic light-emitting display panel, a liquid crystal display panel, an electrophoretic display panel, a miniature light-emitting diode display panel, a micro-light-emitting diode display panel, an electrowetting display panel, and a quantum dot light-emitting display panel. However, display panel 110 is not limited thereto, and any panel capable of displaying an image can be display panel 110 according to embodiments of this disclosure. The shape or size of display panel 110 is not limited.

[0068] The display panel 110 overlaps with the transmissive area TA. Since the display panel 110 is configured to overlap with the transmissive area TA of the cover substrate 130, the image displayed on the display panel 110 can be viewed from the outside through the transmissive area TA. Viewers can visually identify the image displayed on the display panel 110 through the transmissive area TA of the cover substrate 130.

[0069] The display panel 110 can be disposed on the rear surface 130b of the cover substrate 130. The cover substrate 130 includes a front surface 130a and a rear surface 130b, where the rear surface 130b refers to the surface of the cover substrate 130 facing the display panel 110. Additionally, the user-visible surface of the cover substrate 130 is referred to as the front surface of the cover substrate 130. An observer can visually identify the image displayed on the display panel 110 through the front surface 130a of the cover substrate 130.

[0070] Furthermore, the side of the display panel 110 facing the cover substrate 130 is referred to as the front side of the display panel 110, and the side opposite to the cover substrate 130 is referred to as the rear side of the display panel 110. (See reference...) Figure 1 and Figure 2 Sometimes the X-axis direction is referred to as the horizontal direction, the Y-axis direction as the vertical direction, and the Z-axis direction as the thickness direction. The screen of the display device 100 can be displayed in the Z-axis direction, and the Z-axis direction can be referred to as the front side. In the following embodiments, the directions of the X-axis, Y-axis, and Z-axis, as well as the definitions of front side and rear side, are the same.

[0071] A display device 100 according to one embodiment of the present disclosure may include a light-shielding layer 210 located on a blocking region BA, a protective film 410 located on the light-shielding layer 210, and a vibration element 510 located on the protective film 410. The light-shielding layer 210, the protective film 410, and the vibration element 510 may be disposed on the rear surface 130b of a cover substrate 130. A first adhesive layer 310 may be disposed between the light-shielding layer 210 and the protective film 410. Through the first adhesive layer 310, the protective film 410 and the vibration element 510 can be stably fixed and attached to the light-shielding layer 210.

[0072] The detailed structures of the light-shielding layer 210, the protective film 410, the vibration element 510, and the first adhesive layer 310 will be described later.

[0073] A display device 100 according to one embodiment of the present disclosure may include a touch unit 120. The touch unit 120 senses a user's touch on the display device 100. For example, the touch unit 120 may be configured to sense the user's touch via a stylus or finger 10. The touch unit 120 may be referred to by various names. The touch unit 120 may also be referred to as a touch screen, touch panel, touchpad, touch surface, etc.

[0074] The touch unit 120 may be disposed between the cover substrate 130 and the display panel 110. The touch unit 120 may be manufactured separately from the display panel 110, or it may be integrally formed with the display panel 110. The touch unit 120 may be connected to or attached to the rear surface 130b of the cover substrate 130.

[0075] However, the embodiments disclosed herein are not limited thereto, and the touch unit 120 can be arranged in various forms. For example, the touch unit 120 can be disposed within the pixel array unit of the display panel 110. In this case, the touch unit 120 can be configured as an in-cell touch panel. Furthermore, the touch electrode layer can serve as the touch unit 120, and the touch sensor layer can also serve as the touch unit 120.

[0076] Reference Figure 2 The display device 100 may include a touch driving circuit 601. The touch driving circuit 601 may include a touch sensing unit 610, a vibration driving unit 620, and a control unit 650.

[0077] Touch sensing unit 610 can be electrically connected to touch unit 120. Touch sensing unit 610 senses touch applied to touch unit 120 and generates touch sensing signal.

[0078] For example, when a touch electrode is touched on the touch unit 120, the touch sensing unit 610 can sense the corresponding input value. The touch sensing unit 610 can generate a touch sensing signal based on the touch input value and sample the touch sensing signal to generate touch sensing data. The touch sensing signal can be analog information such as a voltage signal, and the touch sensing data can be digital information converted into digital form, but is not limited to these.

[0079] Control unit 650 controls touch sensing unit 610 and vibration driving unit 620. Control unit 650 can generate control signals for controlling the operation of touch sensing unit 610 and vibration driving unit 620, and send the generated control signals to each of touch sensing unit 610 and vibration driving unit 620. Furthermore, control unit 650 can use touch sensing signals or touch sensing data received from touch sensing unit 610 to execute touch algorithms to determine the presence or absence of touch input and the touch location. Control unit 650 can be electrically connected to vibration element 510 and vibration driving unit 620.

[0080] The vibration drive unit 620 is electrically connected to the vibration element 510 and can apply a vibration drive signal to the vibration element 510 to cause it to vibrate. The vibration drive unit 620 can generate a vibration drive signal based on a touch sensing signal and provide it to the vibration element 510. The vibration drive unit 620 can also generate a vibration drive signal under the control of the control unit 650 and provide it to the vibration element 510. In addition to touch operations, the vibration drive unit 620 can generate vibration drive signals for system notifications (e.g., low battery, low memory, security notifications, etc.), incoming messages or telephone calls, program notifications, etc., but is not limited to these.

[0081] Figure 3 yes Figure 2 A schematic diagram of the touch unit 120, touch sensing unit 610 and control unit 650. Figure 3 A touch panel with touch unit 120 is shown.

[0082] Reference Figure 3 The touch unit 120 may include a plurality of touch electrodes 121 and a plurality of touch lines 122 for electrically connecting the plurality of touch electrodes 121 to the touch sensing unit 610. The touch sensor may be formed by the touch electrodes 121 and the touch lines 122.

[0083] The touch sensing unit 610 can provide touch drive signals TDS to all or part of the plurality of touch electrodes 121, sense all or part of the plurality of touch electrodes 121, generate touch sensing signals or touch sensing data, and provide the generated touch sensing signals or touch sensing data to the control unit 650.

[0084] Figure 4 This is a plan view of the rear surface 130b of the cover substrate 130 of a display device 100 according to an embodiment of the present disclosure, and Figure 5 It is along Figure 4 The cross-sectional view taken from line II-II'.

[0085] Reference Figure 4 and Figure 5 A light-shielding layer 210 is disposed on the rear surface 130b of the cover substrate 130. The light-shielding layer 210 may be disposed on the blocking region BA of the cover substrate 130. The light-shielding layer 210 blocks light incident on the cover substrate 130 from passing through the blocking region BA.

[0086] The transmission region TA and the blocking region BA can be defined by the light-shielding layer 210. The area surrounded by the light-shielding layer 210 can become the transmission region TA of the substrate 130, and the area where the light-shielding layer 210 is provided can become the blocking region BA of the substrate 130.

[0087] The light-shielding layer 210 has light-shielding properties. The light-shielding layer 210 can be formed of a light-shielding material. The light-shielding layer 210 can absorb light.

[0088] For example, the light-shielding layer 210 can be formed of the same material as the black background used to distinguish each color area in the color filter. However, the material used to form the light-shielding layer 210 is not limited to this, and any material capable of blocking light can be used without restriction as the material for forming the light-shielding layer 210.

[0089] The light-shielding layer 210 can contact the cover substrate 130. The light-shielding layer 210 is disposed in the blocking region BA of the cover substrate 130. The light-shielding layer 210 can be formed on the blocking region BA by coating, but is not limited thereto. The light-shielding layer 210 can be formed by deposition on the blocking region BA, or a light-shielding film can be attached to the blocking region BA to form the light-shielding layer 210.

[0090] The light-shielding layer 210 includes an opening OA. A portion of the cover substrate 130 can be exposed from the light-shielding layer 210 through the opening OA. After the light-shielding layer 210 is formed, a portion of the material constituting the light-shielding layer 210 can be removed to form the opening OA. A portion of the cover substrate 130 is exposed from the light-shielding layer 210 through the opening OA. The light-shielding layer 210 may have two or more openings OA.

[0091] Despite Figure 4 In this context, the opening OA is depicted as having a rectangular shape, but the shape of the opening OA is not limited to this. The opening OA can have various planar shapes other than rectangles. For example, the opening OA can have planar shapes such as circles, ellipses, or polygons.

[0092] refer to Figure 4 and Figure 5 A protective film 410 can be provided on the light-shielding layer 210, and a vibration element 510 can be provided on the protective film 410. Additionally, a first adhesive layer 310 can be provided between the light-shielding layer 210 and the protective film 410. Therefore, the protective film 410 can cover the opening. Furthermore, the protective film 410 can cover a portion of the light-shielding layer 210.

[0093] The first adhesive layer 310 is used to fix the protective film 410 and the vibrating element 510 to the cover substrate 130. The first adhesive layer 310 may be disposed on the light-shielding layer 210. At least a portion of the first adhesive layer 310 may be disposed in the opening OA of the light-shielding layer 210.

[0094] The first adhesive layer 310 can be light-shielding. Because the first adhesive layer 310 is light-shielding, even if an opening OA is formed in the light-shielding layer 210, it may block the transmission of light through the opening OA. Even if the vibrating element 510 is placed on the opening OA where no light-shielding material is provided, the user may not be able to see the vibrating element 510.

[0095] The first adhesive layer 310 may include an adhesive polymer. The adhesive polymer may have both adhesive and tack properties. Therefore, the adhesive polymer may also be referred to as a tacky polymer. Examples of adhesive polymers include acrylic resins, urethane resins, and epoxy resins. However, the adhesive polymer is not limited to these, and other adhesive polymers known in the art may be applied to the first adhesive layer 310.

[0096] The first adhesive layer 310 may include a light-blocking additive dispersed in the adhesive polymer. Any material capable of blocking light can be used as the light-blocking additive, but there are no limitations.

[0097] For example, carbon black can be used as a light-shielding additive. Carbon black can be considered a black pigment. However, light-shielding additives are not limited to this; at least one of black pigments and black dyes can also be used as light-shielding additives. Besides carbon black, other colored particles with light-shielding effects can also be used as light-shielding additives. For example, silica particles, titanium dioxide particles, and alumina can be used as light-shielding additives. In addition to pigments or dyes, UV diffusing agents such as metal nanoparticles and UV diffusing agent beads can also be used as additives.

[0098] The first adhesive layer 310 may have an optical density of 1.5 or greater. Optical density is a value that represents the degree to which the intensity of light decreases after passing through an object. Optical density is defined as the logarithm of the ratio of the intensity of light incident on the object to the intensity of light transmitted through the object. When the intensity of light incident on the object is I0 and the intensity of light after passing through the object is I1, the optical density A can be obtained by Equation 1.

[0099] [Formula 1]

[0100] Optical density = log I0 / I1

[0101] A light density of 1.5 or higher corresponds to a light transmittance of 3.16% or less. When the light density of the first adhesive layer 310 is 1.5 or higher, even if light is incident through the opening OA of the light-shielding layer 210, light transmission can be suppressed by the first adhesive layer 310.

[0102] Specifically, the first adhesive layer 310 may have an optical density of 1.5 to 3.5, an optical density of 1.5 to 2.5, an optical density of 1.5 to 2.0, or an optical density of 2.0 to 2.5.

[0103] The protective film 410 can be disposed on the first adhesive layer 310. The protective film 410 can contact the first adhesive layer 310. The protective film 410 can be disposed on the light-shielding layer 210 and simultaneously adhered to the first adhesive layer 310.

[0104] The protective film 410 has light-blocking properties. Therefore, light can be blocked by the protective film 410. Light incident through the opening OA of the light-blocking layer 210 can be blocked by the protective film 410.

[0105] The protective film 410 overlaps with the opening OA of the light-shielding layer 210. (Refer to...) Figure 4 In the plan view, the protective film 410 covers the entire opening OA of the light-shielding layer 210. The protective film 410 has a larger area than the opening OA and can cover the entire opening OA. As a result, light incident through the opening OA can be blocked by the protective film 410. In the plan view, a portion of the protective film 410 can extend to the outside of the opening OA and overlap with the light-shielding layer 210.

[0106] There are no particular limitations on the material of the protective film 410. A film or sheet with light-shielding properties can be used as the protective film 410 of the display device 100 according to one embodiment of the present disclosure.

[0107] For example, the protective film 410 may include a polymer film resin and a light absorber dispersed in the polymer film resin.

[0108] The polymer film resin may include at least one of polyethylene terephthalate (PET), polyimide (PI), polyamide (PA), polycarbonate (PC), polyacrylic acid, and polyurethane.

[0109] Light absorbers may include black pigments or black dyes. Light absorbers may include at least one of, for example, carbon black, silica particles, titanium dioxide particles, alumina particles, and metal nanoparticles (nanometals).

[0110] The vibration element 510 is disposed on the protective film 410. The vibration element 510 can be fixed on the protective film 410. Alternatively, the vibration element 510 can be integrally formed with the protective film 410.

[0111] Reference Figure 4 and Figure 5The protective film 410 and the vibrating element 510 can overlap with the opening OA of the light-shielding layer 210, respectively. Therefore, the first adhesive layer 310 can contact the protective film 410 and simultaneously contact the cover substrate 130 at the opening OA. The first adhesive layer 310 can contact both the protective film 410 and the cover substrate 130 at the opening OA. When the vibrating element 510 is stably fixed to the protective film 410 and the first adhesive layer 310 is in contact with both the protective film 410 and the cover substrate 130, the vibrating element 510 can be stably attached to the cover substrate 130 via the first adhesive layer 310.

[0112] When at least a portion of the first adhesive layer 310 directly contacts the cover substrate 130, the first adhesive layer 310 can adhere more firmly to the cover substrate 130 compared to when the first adhesive layer 310 only directly contacts the light-shielding layer 210. Therefore, the vibration element 510 can be firmly attached to the cover substrate 130.

[0113] Furthermore, when the first adhesive layer 310 directly contacts the cover substrate 130, it can prevent or reduce the phenomenon that the light-shielding layer 210 peels off or separates from the cover substrate 130 due to the vibration of the vibration element 510. As a result, the vibration element 510 can be stably fixed on the cover substrate 130 without causing the light-shielding layer 210 to lift or peel off.

[0114] Although the first adhesive layer 310 is in contact with the light-shielding layer 210, the adhesive force used to fix the protective film 410 and the vibration element 510 to the cover substrate 130 mainly occurs at the joint between the first adhesive layer 310 and the cover substrate 130. Therefore, even if the vibration element 510 vibrates, the phenomenon of the light-shielding layer 210 peeling or separating from the cover substrate 130 can be suppressed or prevented.

[0115] The vibrating element 510 can be disposed on an area covered by at least one of the light-shielding layer 210 and the protective film 410. (Refer to...) Figure 4 In the plan view, the vibrating element 510 can be positioned within the area where the protective film 410 is provided. Therefore, the vibrating element 510 may be invisible to the user. Since the protective film 410 has light-blocking properties, even if an opening OA is formed in the light-blocking layer 210, it can prevent or reduce the user from seeing the vibrating element 510 through the opening OA.

[0116] As a vibrating element 510, an actuator or a piezoelectric element can be used, but it is not limited to these.

[0117] Reference Figure 5 The vibration element 510 may include a first electrode 511, a piezoelectric layer 513 on the first electrode 511, and a second electrode 512 on the piezoelectric layer 513.

[0118] The first electrode 511 and the second electrode 512 are spaced apart from each other by a piezoelectric layer 513 inserted therebetween, and at least a portion of the first electrode 511 and the second electrode 512 may be formed of a metallic material with low resistance and excellent heat dissipation properties. Alternatively, the first electrode 511 and the second electrode 512 may comprise a transparent conductive oxide or a conductive polymer.

[0119] The first electrode 511 and the second electrode 512 may each include metals containing silver (Ag), magnesium (Mg), aluminum (Al), copper (Cu), platinum (Pt), palladium (Pd), gold (Au), nickel (Ni), neodymium (Nd), iridium (Ir), and chromium (Cr), transparent conductive oxides including ITO (InSnO), IZO (InZnSnO), ZnO, and In2O3, and conductive polymers including polyaniline, polypyrrole, and polythiophene.

[0120] The piezoelectric layer 513 comprises a piezoelectric material. The piezoelectric material can vibrate due to an electric field. When pressure or torsion is applied to the crystal structure of the piezoelectric material by an external force, a potential difference can be generated in the piezoelectric material due to dielectric polarization caused by changes in the relative positions of positive (+) ions and negative (-) ions. Conversely, when an electric field is applied to the piezoelectric material, the piezoelectric material can vibrate.

[0121] Reference Figure 5 The vibrating element 510 can be connected to a first connecting line 515 and a second connecting line 516. The first connecting line 515 can be connected to a first electrode 511, and the second connecting line 516 can be connected to a second electrode 512. The first connecting line 515 and the second connecting line 516 can be connected to an external terminal, an external pad, or a drive circuit, respectively.

[0122] The first connecting line 515 can be integrally formed with the first electrode 511, and the second connecting line 516 can be integrally formed with the second electrode 512. Although not shown in the figures, the first connecting line and the second connecting line can be formed separately from the first electrode and the second electrode, respectively. Furthermore, the first electrode and the second electrode can have a multilayer structure, and multiple piezoelectric layers can be disposed between the first electrode and the second electrode.

[0123] The first electrode 511 and the second electrode 512 can be connected to the vibration drive unit 620 via the first connecting line 515 and the second connecting line 516, respectively, and the vibration element 510 can vibrate in response to a touch applied to the touch unit 120.

[0124] For example, the first connecting line 515 can provide a vibration drive signal to the vibration element 510. The vibration drive signal generated from the vibration drive unit 620 can be input to the first electrode 511 of the vibration element 510 through the first connecting line 515. Multiple vibration elements 510 can be independently connected to the first connecting line 515.

[0125] The second connecting line 516 is connected to the second electrode 512 and can apply a common voltage to the vibrating element 510. The second electrode 512 can also be connected to a ground terminal. Alternatively, multiple vibrating elements 510 can be connected to a single second connecting line 516.

[0126] Figure 6 This is a cross-sectional view of a display device 200 according to another embodiment of the present disclosure. In detail, Figure 6 It shows the corresponding Figure 5 The cross-section, and Figure 6 The configuration shown is the same as Figure 5 The difference shown in the configuration is that Figure 6 It also includes a second adhesive layer 320. In the following text, to avoid repetition, descriptions of already described components will be omitted.

[0127] refer to Figure 6 The display device 200 includes a second adhesive layer 320 between a protective film 410 and a vibrating element 510. The second adhesive layer 320 is used to fix the protective film 410 to the vibrating element 510.

[0128] The second adhesive layer 320 may include an adhesive polymer. Examples of adhesive polymers include acrylic resins, urethane resins, and epoxy resins. However, the adhesive polymer is not limited to these, and other adhesive polymers known in the art may be applied to the second adhesive layer 320.

[0129] The second adhesive layer 320 may include additives dispersed in the adhesive polymer. There are no particular limitations on the type of additives included in the second adhesive layer 320. For example, additives for improving adhesive strength and additives for preventing static electricity can be used.

[0130] The vibration element 510 can be stably fixed to the protective film 410 by the second adhesive layer 320, and the vibration element 510 can be prevented or reduced from separating from the protective film 410.

[0131] Figure 7 This is a plan view of the rear surface 130b of the cover substrate 130 applied to the display device 300 according to another embodiment of the present disclosure.

[0132] Reference Figure 7A protective film 410 can be disposed on two or more openings OA. In this case, a protective film 410 can extend in one direction to cover multiple adjacent openings OA.

[0133] According to another embodiment of this disclosure, when a protective film 410 is configured to cover multiple openings OA, the process of setting the protective film 410 can be simplified and the setting efficiency of the protective film 410 can be improved.

[0134] In addition, multiple vibration elements 510 can be disposed on a single protective film 410. When multiple vibration elements 510 are disposed on a single protective film 410, the efficiency of disposing of the vibration elements 510 can be improved, and the manufacturing cost of the display device 300 can be reduced.

[0135] Even if multiple vibration elements 510 are arranged on a single protective film 410, each of the multiple vibration elements 510 can be configured to overlap with the opening OA of the light-shielding layer 210. In this case, the vibration of the vibration element 510 can be effectively transmitted to the cover substrate 130.

[0136] Figure 8 This is a plan view of the rear surface 130b of the cover substrate of a display device 400 according to another embodiment of the present disclosure, and Figure 9 It is along Figure 8 The cross-sectional view taken from line III-III'.

[0137] Reference Figure 8 and Figure 9 Multiple vibration elements 510 can be set on an opening OA.

[0138] exist Figure 8 In the case of the light-shielding layer 210, the opening OA can be formed in a long strip along one side of the cover substrate 130. The protective film 410 can cover the entire opening OA in a plan view. The first adhesive layer 310 is disposed between the opening OA and the protective film 410. The first adhesive layer 310 can extend over the entire opening OA and extend to the outside of the opening OA, and is disposed on the light-shielding layer 210.

[0139] like Figure 8 As shown, by arranging multiple vibration elements 510 on an opening OA and a protective film 410, the operating efficiency of the vibration elements 510 can be improved, and the manufacturing cost of the display device 300 can be reduced.

[0140] like Figure 8As shown, when the first adhesive layer 310 is disposed in the elongated opening OA along one side of the cover substrate 130, the contact area between the first adhesive layer 310 and the cover substrate 130 can be increased. Therefore, the bonding strength through the first adhesive layer 310 increases, and the protective film 410 and the vibrating element 510 can be stably attached to the cover substrate 130 via the first adhesive layer 310. Furthermore, since the area of ​​the first adhesive layer 310 directly contacting the cover substrate 130 is large, and the vibrating element 510 can be firmly attached to the cover substrate 130, the vibration of the vibrating element 510 can be effectively transmitted to the cover substrate 130.

[0141] Reference Figure 8 and Figure 9 The vibrating element 510 may not be disposed on the opening OA and a portion of the first adhesive layer 310. Even if the vibrating element 510 is not disposed on the opening OA, light transmission through the opening OA can still be blocked by the first adhesive layer 310 and the protective film 410.

[0142] Figure 10 This is a cross-sectional view of a display device 500 according to another embodiment of the present disclosure. Figure 10 It shows the corresponding Figure 9 The cross-section at the location, where Figure 10 The configuration shown is the same as Figure 9 The difference in the configuration shown is that it also includes a second adhesive layer 320.

[0143] refer to Figure 10 The second adhesive layer 320 can be disposed between the protective film 410 and the vibrating element 510. The second adhesive layer 320 is used to fix the protective film 410 to the vibrating element 510.

[0144] The vibrating element 510 can be stably fixed to the protective film 410 by the second adhesive layer 320, and the second adhesive layer 320 can prevent or reduce the separation of the vibrating element 510 from the protective film 410. Since the second adhesive layer 320 has already been described, its detailed description is omitted.

[0145] Figure 11 This is a cross-sectional view of a display device 600 according to another embodiment of the present disclosure. Figure 11 It shows the relationship with Figure 5 The cross-section at the corresponding position, where Figure 11 The configuration shown is the same as Figure 5 The difference shown in the configuration is that Figure 11 It also includes sealing material 450.

[0146] refer to Figure 11The display device 600 may include a sealing material 450 that contacts the first adhesive layer 310 and the protective film 410. The sealing material 450 can improve the adhesion stability of the first adhesive layer 310 and the protective film 410, thereby improving the fixation stability of the vibrating element 510.

[0147] The sealing material 450 can contact the side surfaces of the first adhesive layer 310 and the protective film 410. Additionally, the sealing material 450 can contact the light-shielding layer 210. The sealing material 450 can contact the upper surface of the light-shielding layer 210.

[0148] By applying uncured sealant 450 to the side of the first adhesive layer 310, the side of the protective film 410, and the upper surface of the light-shielding layer 210, and then curing it, the adhesive stability of the first adhesive layer 310 and the protective film 410 can be improved.

[0149] The sealing material 450 may include a curable resin and a light-shielding additive dispersed in the curable resin. The light-shielding additive may include at least one of, for example, carbon black, silica particles, titanium dioxide particles, alumina particles, and metal nanoparticles (nanometals). However, the sealing material 450 is not limited thereto, and any known sealing material may be used as the sealing material 450 of the display device 600.

[0150] Figure 12 This is a cross-sectional view of a display device 700 according to another embodiment of the present disclosure. Figure 12 It shows the relationship with Figure 5 The cross-section at the corresponding position, where Figure 12 The configuration shown is the same as Figure 5 The difference in the configuration shown is that Figure 12 It also includes a second adhesive layer 320 and a light-shielding film 420.

[0151] refer to Figure 12 The display device 700 may also include a light-shielding film 420 on the vibrating element 510. The light-shielding film 420 protects the vibrating element 510. The light-shielding film 420 may be disposed on the upper surface of the vibrating element 510 or on the side of the vibrating element 510. The light-shielding film 420 blocks light, thereby preventing or reducing the vibrating element 510 from being unnecessarily seen from the outside.

[0153] refer to Figure 13A and Figure 13BThe light-shielding patterns 225 and 226 can be disposed in the opening OA of the light-shielding layer 210. The light-shielding patterns 225 and 226 can be made of the same material as the material forming the light-shielding layer 210. However, the light-shielding patterns 225 and 226 are not limited thereto, and the light-shielding patterns 225 and 226 can be made of a different material than the material forming the light-shielding layer 210.

[0154] In the process of forming the opening OA, a portion of the material forming the light-shielding layer 210 can be retained instead of being removed, thereby forming light-shielding patterns 225 and 226. Alternatively, the light-shielding patterns 225 and 226 can be formed in a separate process after the opening OA is formed. When the light-shielding patterns 225 and 226 are provided in the opening OA, the light-shielding efficiency can be improved.

[0155] There are no particular restrictions on the shape of the light-blocking patterns 225 and 226. For example... Figure 13A As shown, the light-shielding pattern 225 can have a dotted plane. (Reference) Figure 13B The light-shielding pattern 226 can have a linear plane. The light-shielding pattern 226 can also have a grid-like plane formed by intersecting lines.

[0185] This disclosure is not limited to the above-described embodiments and drawings. It will be apparent to those skilled in the art that various substitutions, modifications and alterations can be made without departing from the technical concept of this disclosure.

[0186] According to one embodiment of this disclosure, since the vibrating element or actuator is disposed on the light-shielding layer for haptic feedback, the display area of ​​the display device can be maintained. According to one embodiment of this disclosure, the vibrating element or actuator can be disposed on top of the light-shielding layer, and can be disposed on top of an opening formed in the light-shielding layer.

[0187] According to one embodiment of this disclosure, an adhesive layer is applied to secure a vibrating element or actuator to a cover substrate, and the adhesive layer directly contacts the cover substrate. Therefore, it is possible to prevent or reduce the light-shielding layer from peeling or separating from the cover substrate due to vibration of the vibrating element or actuator. Furthermore, because the adhesive layer directly contacts the cover substrate, the vibrating element or actuator can be stably secured to the cover substrate.

[0188] According to one embodiment of this disclosure, the adhesive layer may include a black dye or black pigment and has light-blocking properties. Because the adhesive layer has light-blocking properties, it can block light incident from the opening even when the adhesive layer is placed in an opening.
