Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display device. Background Technology

[0002] The speakers in display devices typically use bottom-firing and rear-firing methods, resulting in a separation between the sound image position and the image position, leading to a poor viewing experience and failing to provide a unified audiovisual experience.

[0003] In related technologies, display devices can generate sound waves by directly vibrating the display panel through a sound exciter, allowing the display panel in the display device to perform both display and speaker diaphragm sound-generating functions, thus achieving a unified audiovisual effect.

[0004] However, the heat dissipation performance of the sound exciter in current display devices is poor. Heat is transferred to the display panel, causing the local temperature of the display panel to rise, resulting in deviations in the brightness and color of the local display of the image. Utility Model Content

[0005] Some embodiments of this application provide a display device that can solve the technical problem that the heat dissipation performance of the sound exciter in current display devices is poor, and the heat is transferred to the display panel, causing the local temperature of the display panel to rise, resulting in deviations in the brightness and color of the local display of the image.

[0006] In some embodiments of this application, a display device is provided, which includes a display panel, a backlight assembly, an actuator, a sound-emitting plate, and a backplate. The display panel is used to display image information. The backlight assembly is located on the light-incident side of the display panel and includes multiple lamp panels that are spliced ​​together. The sound-emitting plate is disposed on the side of the backlight assembly away from the display panel and is connected to a first splicing position of adjacent lamp panels, covering the first splicing position. The actuator is disposed on the side of the sound-emitting plate away from the backlight assembly and is configured to drive the sound-emitting plate to vibrate. The actuator includes an actuator body, an actuator, and a spring. The actuator is connected to the sound-emitting plate, a first end of the spring is connected to the actuator body, a second end of the spring is connected to the actuator, and is configured to transfer heat from the actuator to the actuator body.

[0007] The display device provided in some embodiments of this application divides the backlight assembly into multiple lamp panels. An exciter drives a sound-emitting panel to vibrate. The sound-emitting panel is located at the first splicing position of the lamp panels, which can drive the lamp panels to vibrate to achieve local vibration and sound generation of the display panel. Lamp panels that are not in contact with the sound-emitting panel will not vibrate and generate sound. While reducing the area of ​​the sound-emitting panel, crosstalk and mutual influence between different lamp panels can be avoided, thereby improving the sound effect while achieving audio-visual synchronization. In addition, the spring wave can dissipate heat from the exciter during vibration, preventing the heat of the exciter from being transferred to the lamp panels and avoiding damage to the lamp panels due to excessively high operating temperature.

[0008] In some embodiments, the display device may further include a back plate disposed on the side of the backlight assembly away from the display panel, the back plate having a protrusion that surrounds the lamp plate to form an accommodating space, and a sound-emitting plate located within the accommodating space.

[0009] In some embodiments, the first splicing position is located in the middle of the display device, and the protrusion covers the first splicing position.

[0010] In some embodiments, the actuator body may include a housing and a magnetic conductor, with one end of the spring bonded to the magnetic conductor and the magnetic conductor connected to the housing.

[0011] This design allows heat to be transferred to the outer casing via the magnetic conductor, improving heat dissipation efficiency.

[0012] In some embodiments, the spinner may include a thermally conductive layer and a fabric layer, with the fabric layer and the thermally conductive layer stacked together; the thermally conductive layer at the end of the spinner is at least partially exposed so that the thermally conductive layer contacts the magnetic conductor.

[0013] This design ensures the good elasticity of the wave while improving the efficiency of heat conduction.

[0014] In some embodiments, the actuator may further include a pressure ring connected between the housing and the magnetic conductor; at least a portion of the pressure ring abuts against the end of the spring.

[0015] This setup can improve the reliability of the bombardment installation.

[0016] In some embodiments, the thermally conductive layer may include a thermally conductive film having a plurality of openings.

[0017] This design can improve the heat transfer efficiency of the heat-conducting layer.

[0018] In some embodiments, the thickness of the thermally conductive film is greater than or equal to 100 μm and less than or equal to 1000 μm.

[0019] In some embodiments, the fabric layer consists of two layers, with the thermally conductive layer sandwiched between the two fabric layers; or, the thermally conductive layer consists of two layers, with the fabric layer sandwiched between the two thermally conductive layers.

[0020] In some embodiments, the sound-emitting plate extends along the splicing gap between two adjacent light panels, and the sound-emitting plate covers a portion of the light panel surface on both sides of the splicing gap.

[0021] In some embodiments, a plurality of exciters are provided on the sound-emitting plate; the plurality of exciters are arranged at intervals along the width direction of the sound-emitting plate, or the plurality of exciters are arranged at intervals along the length direction of the sound-emitting plate.

[0022] In some embodiments, there may be multiple sound-emitting panels, which are spaced apart on the side of the lamp panel away from the display panel; at least one sound-emitting panel is provided with an exciter.

[0023] Some embodiments of this application provide a display device including a display panel, a backlight assembly, an actuator, a sound-emitting plate, and a backplate. The display panel is used to display image information. The backlight assembly is located on the light-incident side of the display panel and includes multiple lamp panels that are spliced ​​together. The sound-emitting plate is disposed on the side of the backlight assembly away from the display panel and is connected to a first splicing position of adjacent lamp panels. The actuator is disposed on the side of the sound-emitting plate away from the backlight assembly and is configured to drive the sound-emitting plate to vibrate. The actuator includes an actuator body, an actuator, and a spring. The spring is connected between the actuator body and the actuator and is configured to transfer heat from the actuator to the actuator body. By reducing the area of ​​the sound-emitting plate, crosstalk and mutual influence between different lamp panels can be avoided. In addition, heat from the actuator is prevented from being transferred to the lamp panels, thus preventing the lamp panels from overheating and being damaged.

[0050] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0051] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application.

Therefore, it should not be construed as a limitation of this application.

[0053] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0054] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0055] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this disclosure. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0056] Flat panel displays, televisions, and other display devices can be used to display images. Taking a liquid crystal display (LCD) device as an example, an LCD device mainly consists of a backlight assembly, a liquid crystal panel, and a driving circuit. The liquid crystal panel, as the display panel, does not emit light itself; it relies on the light source provided by the optical elements in the backlight assembly to achieve brightness display. The display principle of an LCD is to place liquid crystal between two conductive glass plates. Driven by the electric field between two electrodes, the liquid crystal molecules undergo a twisting nematic electric field effect, which controls the transmission or blocking function of the backlight, thereby displaying the image. Adding a color filter allows for the display of color images.

[0057] In the display device, the backlight module can be a direct-lit backlight module. In this case, the backlight module has a lamp panel to provide backlight to the display panel through the light source of the lamp panel. When the lamp panel vibrates, it compresses the gas in the cavity on the light-emitting side of the lamp panel, and transmits the vibration to the display panel through the cavity to drive the display panel to vibrate. The display panel produces sound through the sound waves emitted by the vibration, so that the display panel can both display images and replace the speaker to produce sound.

[0058] The gap size of the cavity on the light-emitting side of the lamp board can be determined according to the light source of the lamp board, for example, the gap size is related to the size of the light source. Light sources such as sub-millimeter light-emitting diodes (e.g., Mini-LEDs) have a more compact size, thus allowing for a smaller gap between the backlight board and the liquid crystal display panel, thereby reducing the cavity thickness and improving the vibration transmission effect. Therefore, in some embodiments of this application, sub-millimeter light-emitting diodes (Mini-LEDs) are used as the light source for the backlight module.

[0059] For example, the cavity gap can be from 0.3mm to 10mm, with a maximum gap of 10mm. Alternatively, the gap can be 0.3mm or 1mm. For instance, when the cavity gap is 1mm, the cavity thickness is relatively small, which improves the transmission efficiency of the vibration force output by the exciter. Or, when the cavity gap is 0.3mm, the exciter is closer to the display panel, resulting in stronger vibration and better sound production. Conversely, when the cavity gap is 10mm, the cavity thickness is relatively large, which can prevent the display panel and the light source from colliding at a certain position during vibration. Specifically, the cavity gap can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, etc. It should be noted that the values ​​and ranges involved in the embodiments of this application are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors, which can be considered negligible by those skilled in the art.

[0060] In related technologies, compared to display devices using OLED light sources, OLED displays are self-emissive screens with inherent flexibility. Therefore, by placing an exciter on the back of the OLED display, the screen can elastically deform and generate sound under the excitation vibration of the exciter. However, in liquid crystal displays (LCDs), which have backlight modules, it's impossible to directly place an exciter on the back of the display panel. Furthermore, the lamp board in the backlight module is relatively rigid, making it difficult to couple and transmit its vibration to the display panel, resulting in low vibration transmission efficiency. Therefore, a support structure can be placed between the display panel and the lamp board in Mini-LED displays or other LCD devices. This support structure acts as a vibration transmission medium, transmitting the vibration of the lamp board to the display panel, thereby improving the transmission efficiency of vibration from the lamp board to the display panel. Additionally, the support structure keeps the gap between the lamp board and the display panel within a preset range, preventing the light source and display panel from colliding at a certain location, thus avoiding collision noise and abrasion risks.

[0061] In addition, the exciter of the current display device has poor heat dissipation performance. The vibration output end of the exciter becomes the only heat transfer path. Since the vibration output end of the exciter is in contact with the lamp plate on the light-incident side of the display panel, heat is transferred to the lamp plate and the display panel, causing the local temperature of the display panel to rise, resulting in damage to the lamp plate and deviations in the brightness and color of the local display of the image.

[0062] Some embodiments of this application provide a display device in which a backlight assembly is divided into multiple independent lamp panels, a sound-emitting panel corresponds to a portion of the lamp panels, and an exciter drives the sound-emitting panel to cause the lamp panels to emit sound locally. The exciter includes an actuator, a spring, and a housing. The spring is connected to the actuator and the housing respectively. The spring transfers the heat of the actuator to the housing for heat dissipation, thereby reducing the temperature of the actuator, preventing damage to the lamp panels, and reducing the impact of local temperature on image display quality.

[0063] <Composition of a display device>

[0064] Figure 1 This is a schematic diagram of the structure of a display device according to some embodiments of this application. Figure 2 This is a cross-sectional view of a display device according to some embodiments of this application. Figure 3 This is a schematic diagram illustrating the relative displacement between different lamp panels in a display device according to some embodiments of this application. Figure 4 This is a schematic diagram of the structure of the exciter in a display device according to some embodiments of this application.

[0065] like Figures 1 to 4 As shown, the display device in some embodiments of this application includes a display panel 100.

[0066] In some embodiments, the display device includes a backlight assembly 200 located on the light-incident side of the display panel 100 and capable of providing the display panel 100 with the light required for display.

[0067] The backlight assembly 200 may include a lamp panel 210, and the display device may also include an optical film assembly 110. The lamp panel 210 is used to emit light and can provide some support for the optical film assembly 110.

[0068] In some embodiments, the display device includes an exciter 400 configured to drive a sound-emitting plate 600 to vibrate. The sound-emitting plate 600 can transmit the vibration to the lamp plate 210, causing the lamp plate 210 to vibrate locally. Different local vibrations of the lamp plate 210 cause the display panel 100 to generate multiple sound-emitting zones. Different sound-emitting zones can correspond to different sound channels, so that the display device can have a multi-channel sound effect.

[0069] In some embodiments, the display device includes a backplate 500 disposed on the side of the backlight assembly 200 away from the display panel 100, and the backplate 500 can support the lamp panel 210.

[0070] It is understood that the backlight assembly 200 includes multiple lamp panels 210, which are spliced ​​together. At least some of the multiple lamp panels 210 can be connected to the back panel 500 so that the multiple lamp panels 210 are relatively independent.

[0071] The lamp panel 210 includes a first lamp panel 210a and a second lamp panel 210b, which are arranged side by side. An exciter 400 can be positioned on the side of the first lamp panel 210a facing away from the display panel 100. A sound-emitting plate 600 can be connected to the first lamp panel 210a, and the exciter 400 is configured to drive the first lamp panel 210a to vibrate via the sound-emitting plate 600. The second lamp panel 210b can be connected to the back plate 500. This allows only a portion of the lamp panels 210 to vibrate and produce sound, improving the accuracy and sensitivity of the sound emission position. Furthermore, the vibration of a portion of the lamp panel 210 has a smaller area and mass, resulting in less energy attenuation during vibration. A better sound emission effect can be achieved with a smaller vibration amplitude, improving the reliability of the device.

[0072] In some embodiments, the sound-emitting panel 600 is connected to the first splicing position of the adjacent lamp panel 210. The back panel 500 has a protrusion 510, which, together with the lamp panel 210, forms an accommodating space 520, in which the sound-emitting panel 600 is located.

[0073] Understandably, a protrusion 510 can be provided on the back plate 500 at the position corresponding to the first lamp panel 210a, and the protrusion 510 can provide space for the installation of the sound-emitting plate 600. The other areas on the back plate 500, excluding the protrusion 510, correspond to the second lamp panel 210b. Accordingly, the second lamp panel 210b can be connected to the area on the back plate 500 where the protrusion 510 is not provided, so as to improve the installation reliability of the lamp panel 210.

[0074] In some embodiments, the exciter 400 includes an exciter body 410.

[0075] In some embodiments, the actuator 400 includes an actuator 420.

[0076] In some embodiments, the actuator 400 includes a spring 430 connected between the actuator body 410 and the actuator 420.

[0077] In some embodiments, the actuator 420 is connected to the sound-emitting plate 600, and the vibration of the actuator 420 can drive the sound-emitting plate 600 to vibrate. The spring wave 430 can transfer the heat generated by the vibration of the exciter 400 to the exciter body 410 through the spring wave 430, avoiding the heat from being directly transferred to the sound-emitting plate 600 through the actuator 420, and thus avoiding the heat from being transferred to the lamp plate 210, thereby preventing the lamp plate 210 from overheating.

[0078] In addition, considering factors such as the size of the display device and the manufacturing process of the lamp board 210, the size of the display device can be matched with the sum of the areas of multiple lamp boards 210, that is, there can be multiple lamp boards 210, and the multiple lamp boards 210 are arranged in an array.

[0079] It should be noted that in some embodiments of the display device of this application, the lamp board 210 can be a Mini-LED board, and the light of each lamp board 210 can be controlled independently, so that the display panel 100 has higher positioning accuracy when displaying images. In addition, the display device can also be a laser TV. The embodiments of this application do not limit the specific image display principle of the display device, as long as the display panel 100 can vibrate and produce sound by vibrating the lamp board 210 through the exciter 400.

[0080] The following sections will describe each part of the display device in turn.

[0081] [Display Panel]

[0082] Please continue to refer to Figures 1 to 4 The display panel 100 is used to display images. The display panel 100 includes a display area and a circuit board located on one side of the display area. The circuit board drives the display of the entire display panel 100.

[0083] The display panel 100 includes a top side, a left side, a right side, and a ground side, wherein the top side and the ground side are opposite to each other, the left side and the right side are opposite to each other, the top side is connected to one end of the left side and one end of the right side respectively, and the ground side is connected to the other end of the left side and the other end of the right side respectively.

[0084] For example, the display panel 100 can be a liquid crystal display panel, which specifically includes a color filter (CF) substrate, a thin film transistor (TFT) substrate (also called an array substrate), and a liquid crystal (LC) layer, with the liquid crystal layer located between the color filter substrate and the array substrate. The TFT substrate has data lines and scan lines. By controlling the energization of the data lines and scan lines, the orientation of the liquid crystal molecules is changed, so that light from the light source is emitted through the color filter substrate to generate an image of a preset color.

[0085] [Optical film assembly]

[0086] Please continue to refer to Figures 1 to 4 The optical film assembly 110 may include a reflective sheet that reflects light generated by the light source in the light-emitting direction, thereby distributing the light emitted by the light source evenly. For example, the reflective sheet may be made of polyethylene glycol terephthalate (PET).

[0087] In some embodiments, the optical film assembly 110 may include a light guide plate, which can utilize refraction and total internal reflection to emit light from its incident side to its emitting side, converting a line light source into a surface light source. For example, the light guide plate may be made of glass, polymethyl methacrylate (PMMA), polycarbonate (PC), etc.

[0088] In some embodiments, the optical film assembly 110 may include components such as optical films. The optical films are located on the light-emitting side of the light guide plate and are configured to brighten the light. The optical films may include one or more films, and may include at least one of prism films and brightening films.

[0089] In some embodiments, the display panel 100 and the optical film assembly 110 can be pressed together to avoid an air gap between the liquid crystal screen and the optical film assembly 110 that allows air to flow between them. Exemplarily, the liquid crystal screen and the optical film assembly 110 can also be bonded together, for example, using photosensitive adhesive (UV adhesive), foam, double-sided tape, etc. Thus, the vibration of the lamp panel 210, after being transmitted to the optical film assembly 110, can be directly transmitted to the display panel 100 through the optical film assembly 110, causing the display panel 100 to vibrate and produce sound.

[0090] In other embodiments, there may be a gap between the display panel 100 and the optical film assembly 110, which is a sealed space. After the light panel 210 vibrates the optical film assembly 110, the vibration of the optical film assembly 110 will compress the space in the gap between the display panel 100 and the optical film assembly 110, thereby causing the display panel 100 to vibrate and produce sound under the action of compressed air by utilizing the viscosity of air.

[0091] In other embodiments, there may be a gap between the display panel 100 and the optical film assembly 110, which is a non-sealed space.

[0092] [Lightboard]

[0093] Please continue to refer to Figures 2 to 4 In some embodiments of this application, there are multiple lamp panels 210, which are assembled together to form a complete light-emitting panel. The lamp panels 210 in the sound-emitting area are connected to the sound-emitting panel 600. The shape of the lamp panels 210 can be square, and the specific length and width dimensions of each lamp panel 210 are not limited in the embodiments of this application.

[0094] Each light panel 210 may be provided with multiple light sources, which may be arranged in an array on the light panel 210. For example, the light source may be a strip light bar provided on the light panel 210, and the light bar has multiple light-emitting diodes (LEDs) arranged in sequence. The light-emitting diodes may be Mini-LEDs. In addition, there may be multiple light bars, which may be arranged in sequence at intervals.

[0095] In some embodiments, the plane of the first lamp plate 210a connected to the sound-emitting plate 600 is parallel to the plane of the second lamp plate 210b where the sound-emitting plate 600 is not provided, so that the first lamp plate 210a and the second lamp plate 210b emit light at the same time when vibrating, and the display panel 100 still has good display quality.

[0096] For example, the sound-emitting plate 600 can be bonded to the first lamp plate 210a with double-sided tape, and the exciter 400 can be bonded to the sound-emitting plate 600 with double-sided tape. The second sound-emitting plate 600 can be bonded to the back plate 500 with double-sided tape, or the second sound-emitting plate 600 can be connected to the back plate 500 by riveting.

[0097] For example, the first lamp panel 210a can be supported by the exciter 400. Alternatively, the first lamp panel 210a can be elastically connected to the back plate 500. For instance, the first lamp panel 210a can cooperate with the lamp panel 210 via a guide post, and a spring is provided on the guide post, with the two ends of the spring abutting against the first lamp panel 210a and the back plate 500 respectively.

[0098] It should be noted that, in the initial state, the plane of the first lamp panel 210a is flush with the plane of the second lamp panel 210b. The exciter 400 drives the sound-emitting plate 600 to vibrate, so that when the first lamp panel 210a vibrates, the first lamp panel 210a moves relative to the second lamp panel 210b. Thus, the vibration of the first lamp panel 210a will not affect the second lamp panel 210b, and the second lamp panel 210b will not affect the vibration amplitude of the first lamp panel 210a. This allows the first lamp panel 210a to have a better vibration effect, thereby improving the sound emission effect of the display panel 100 in the area corresponding to the first lamp panel 210a.

[0099] For example, the multiple light panels 210 can be arranged in two rows, one above the other. The lower row consists of multiple second light panels 210b, and the corresponding display panel 100 can emit bass sound. The upper row consists of multiple first light panels 210a or a combination of first light panels 210a and second light panels 210b, used to form the sound emission zone of each channel. The second light panels 210b located in the lower row can form a bass zone 206, used to emit low-frequency sounds.

[0100] The following provides detailed examples of different numbers of vocal zones.

[0101] Figure 13 This is a schematic diagram showing the distribution of a first type of sound-emitting zone in a display device according to some embodiments of this application.

[0102] Please refer to Figure 13 In a first possible implementation, the multiple sound-emitting zones may include a left main channel zone 201 and a right main channel zone 202, which are symmetrically arranged with respect to the central axis of the display device. The left main channel zone 201 and the right main channel zone 202 each correspond to at least two first lamp panels 210a. A second lamp panel 210b is disposed between the left main channel zone 201 and the right main channel zone 202.

[0103] Understandably, the left main channel area 201 can be equipped with two first light panels 210a, and the right main channel area 202 can be equipped with two first light panels 210a. Each first light panel 210a is equipped with an exciter 400, and each exciter 400 independently drives the vibration of its respective first light panel 210a. This avoids mutual interference between the vibrations of the left main channel area 201 and the right main channel area 202.

[0104] Figure 14 This is a schematic diagram showing the distribution of a second type of sound-emitting zone in a display device according to some embodiments of this application.

[0105] Please refer to Figure 14 In a second possible implementation, the multiple sound-emitting zones may include a left main channel zone 201, a right main channel zone 202, and a center channel zone 203, which are arranged adjacent to each other along the length of the display panel 100. The left main channel zone 201, center channel zone 203, and right main channel zone 202 each correspond to at least two first light panels 210a. A second light panel 210b is provided on the side of the left main channel zone 201 opposite to the center channel zone 203. A second light panel 210b is also provided on the side of the right main channel zone 202 opposite to the center channel zone 203.

[0106] Understandably, the left main channel area 201, the right main channel area 202, and the center channel area 203 can each have two first light panels 210a. Each first light panel 210a is equipped with an exciter 400, which independently drives the vibration of each first light panel 210a. This avoids mutual interference between the vibrations of the left main channel area 201, the right main channel area 202, and the center channel area 203.

[0107] Figure 15This is a schematic diagram showing the distribution of a third sound-emitting zone in a display device according to some embodiments of this application.

[0108] Please refer to Figure 15 In a third possible implementation, the multiple sound-emitting zones may include a left main channel zone 201, a right main channel zone 202, a center channel zone 203, a left surround channel zone 204, and a right surround channel zone 205. The left surround channel zone 204, left main channel zone 201, center channel zone 203, right main channel zone 202, and right surround channel zone 205 are arranged adjacent to each other along the length of the display panel 100. The second lamp panel 210b is located below the sound-emitting zones.

[0109] Understandably, the difference from the previous implementation lies in the addition of a left surround channel area 204 and a right surround channel area 205. The left surround channel area 204 can be equipped with a corresponding first light panel 210a, and the right surround channel area 205 can be equipped with a corresponding first light panel 210a. Each first light panel 210a is equipped with an exciter 400, and each exciter 400 independently drives the vibration of its respective first light panel 210a. This avoids mutual interference between the vibrations of the left main channel area 201, right main channel area 202, center channel area 203, left surround channel area 204, and right surround channel area 205. The left and right channels, as well as the surround channels, can all emit sound towards the front of the display panel 100 of the display device, resulting in better sound quality.

[0110] Figure 16 This is a schematic diagram showing the distribution of a fourth sound-emitting zone in a display device according to some embodiments of this application.

[0111] Please refer to Figure 16 In the fourth possible implementation, the multiple sound zones may include a left main channel zone 201, a right main channel zone 202, a left surround channel zone 204, and a right surround channel zone 205. The difference from the third implementation is that the fourth implementation does not include a center channel zone 203. The specific layout of the light panel 210 for this implementation will not be described in detail in this embodiment.

[0112] Figure 17 This is a schematic diagram showing the distribution of the actuators in some embodiments of the display device of this application.

[0113] It should be noted that in some embodiments of this application, a greater number of sound-emitting zones can be set, and other arrangements of sound-emitting zones can be adopted. This is only necessary because the first lamp plates 210a corresponding to each sound-emitting zone are independent of each other and are directly driven to vibrate by different exciters 400. Each lamp plate 210 can be provided with one, two, or more exciters 400, which can be arranged at intervals along the horizontal direction. Alternatively, please refer to... Figure 17The exciters 400 can be arranged at intervals along the vertical direction, but this application embodiment does not specifically limit this.

[0114] [Soundboard]

[0115] Figure 5 This is a schematic diagram illustrating the arrangement of the sound-emitting plate and exciter in the display device of some embodiments of this application. Figure 1 .

[0116] Please refer to Figures 2 to 5 In some embodiments of this application, the sound-emitting board 600 can be a honeycomb board, and the sound-emitting area corresponding to the lamp board 210 can be provided with a complete honeycomb board, or multiple honeycomb boards can be provided with intervals.

[0117] In some embodiments, the sound-emitting plate 600 extends along the splicing gap between two adjacent lamp panels 210, and the sound-emitting plate 600 covers a portion of the surface of the lamp panels 210 on both sides of the splicing gap. In this way, when the sound-emitting plate 600 drives the multiple first lamp panels 210a to vibrate, it can ensure good sealing between adjacent first lamp panels 210a, thereby ensuring good airtightness of the gas layer between the lamp panels 210 and the optical film assembly 110. Furthermore, the vibration of the first lamp panels 210a can be transmitted to the optical film assembly 110 through the viscosity of the space within the gas layer. The sound-emitting plate 600 covers the splicing gap at the first splicing position.

[0118] Figure 6 This is a schematic diagram illustrating the arrangement of the sound-emitting plate and exciter in the display device of some embodiments of this application. Figure 2 , Figure 7 This is a schematic diagram illustrating the arrangement of the sound-emitting plate and exciter in the display device of some embodiments of this application. Figure 3 .

[0119] Understandably, multiple exciters 400 can be installed on the sound-generating plate 600. Please refer to... Figure 6 Multiple exciters 400 are arranged at intervals along the width of the sound-generating plate 600. Alternatively, please refer to... Figure 7 Multiple exciters 400 are arranged at intervals along the length of the sound-generating plate 600. The specific arrangement of the exciters 400 can be set according to the specific length and width dimensions of the sound-generating plate 600, and this embodiment does not impose specific limitations on this.

[0120] Figure 8 This is a schematic diagram illustrating the arrangement of the sound-emitting plate and exciter in the display device of some embodiments of this application. Figure 4 .

[0121] For example, there may be multiple sound-emitting panels 600, which are spaced apart on the side of the lamp panel 210 opposite to the display panel 100. At least one sound-emitting panel 600 is provided with an exciter 400. For example, please refer to Figure 8 Three sound-emitting plates 600 can be set, all of which extend along the height direction of the display device and are parallel to each other. The middle sound-emitting plate 600 does not have an exciter 400, while the two side sound-emitting plates 600 are each equipped with an exciter 400. The positions of the exciters 400 on the two side sound-emitting plates 600 can be symmetrically arranged with respect to the central axis of the display device.

[0122] [Backplate]

[0123] Please continue to refer to Figures 2 to 5 In some embodiments of this application, the back plate 500 may be square, and the back plate 500 serves to support the lamp plate 210 on the side of the lamp plate 210 away from the display panel 100. The actuator 400 and the back plate 500 may be located on the same side of the lamp plate 210, and the gap between the back plate 500 and the lamp plate 210 is small. The actuator 400 may be located on the side of the back plate 500 away from the lamp plate 210 and pass through the back plate 500 to connect with the lamp plate 210.

[0124] Understandably, in order to accommodate the sound-emitting plate 600 between the back plate 500 and the lamp plate 210, a protrusion 510 is provided on the back plate 500 corresponding to the area on the lamp plate 210 where the sound-emitting plate 600 is connected. The protrusion 510 protrudes in a direction away from the lamp plate 210 relative to other areas of the back plate 500. In this way, when the exciter 400 drives the sound-emitting plate 600 to vibrate, interference between the sound-emitting plate 600 and the back plate 500 can be avoided.

[0125] The back plate 500 and the lamp plate 210 can be flat. Since the exciter 400 directly passes through the back plate 500 and connects to the lamp plate 210, there is no need to reserve a gap between the back plate 500 and the lamp plate 210 to set up the sound plate 600, thus reducing the overall thickness of the machine.

[0126] In some embodiments, the sound-emitting plate 600 is connected to a first splicing position of an adjacent light plate 210, the first splicing position being located in the middle of the display device, and the protrusion covering the first splicing position.

[0127] For example, the first splicing position can be a splicing seam extending vertically in the middle of the display device, and the first splicing position can coincide with the central axis of the display device; or it can be parallel to the central axis of the display device and near the central axis of the display device. This arrangement allows the lamp panel 210 to vibrate with a smaller area and a smaller mass, resulting in less energy attenuation during vibration, and achieving a better sound generation effect with a smaller vibration amplitude.

[0128] In some embodiments, the display device may further include a first adhesive member, with a gap between the back plate 500 and the lamp plate 210, the first adhesive member being disposed in the gap, and both sides of the first adhesive member being bonded to the back plate 500 and the lamp plate 210 respectively, thereby improving the installation stability of the lamp plate 210.

[0129] It is understandable that the first adhesive can be a double-sided adhesive strip with a certain thickness. Each light panel 210 is bonded to the back plate 500 through the first adhesive. Since the back plate 500 is a complete whole, fixing each light panel 210 to the back plate 500 through the first adhesive can ensure that the multiple light panels 210 have precise installation positions relative to each other and avoid interference between local light panels 210 and other light panels 210 when vibrating.

[0130] In some embodiments, the first adhesive is located between two adjacent lamp panels 210; the first adhesive extends along the seam between the two adjacent lamp panels 210, thereby ensuring good sealing between the adjacent lamp panels 210.

[0131] It is understood that the optical film assembly 110 is disposed between the lamp panel 210 and the display panel 100; there is a sealed gas layer M between the lamp panel 210 and the optical film assembly 110. When the exciter 400 drives the lamp panel 210 to vibrate, the lamp panel 210 drives the display panel 100 to vibrate and produce sound through the gas layer M, which can improve the vibration transmission efficiency from the lamp panel 210 to the display panel 100.

[0132] The first adhesive component is simultaneously bonded between two adjacent lamp panels 210, ensuring good sealing of the gas layer M between the lamp panel 210 and the optical film assembly 110. Vibration is transmitted to the optical film assembly 110 and the front display panel 100 through the air in the gas layer M, thereby achieving the integration of sound generation and image display.

[0133] In some embodiments, the gas layer M may not be sealed.

[0134] In some embodiments, the display device may further include a second adhesive member, the first side of which may be bonded to the lamp panel 210; the back plate 500 is provided with an opening 503, through which the exciter 400 passes and is bonded to the second side of the second adhesive member, thereby ensuring that the back plate 500 is positioned as close as possible to the lamp panel 210, reducing the overall thickness of the display device.

[0135] For example, the second adhesive could be double-sided tape.

[0136] In some embodiments of this application, the lamp panel 210 may also be connected to the back panel 500 in other ways, including but not limited to snap-fit, threaded fastener, support plate, elastic block, etc.

[0137] For example, the light panel 210 and the back panel 500 may each be provided with interlocking buckles, and when the light panel 210 and the back panel 500 are assembled, the buckles on the two are interlocked.

[0138] For example, the lamp panel 210 and the back plate 500 are respectively provided with mounting holes, and the two can be connected from one side of the back plate by using threaded fasteners passing through the mounting holes on the lamp panel 210 and the back plate 500.

[0139] For example, the lamp panel 210 and the back panel 500 can be connected by a support plate. The support plate is elastic, and its two ends are connected to the lamp panel 210 and the back panel 500 by screws or by double-sided adhesive.

[0140] For example, the lamp panel 210 and the back panel 500 can be connected by an elastic block. The elastic block can be cylindrical, frustum-shaped, or other structures. The two ends of the elastic block can abut against the lamp panel 210 and the back panel 500 respectively, and the two ends of the elastic block can be bonded to the lamp panel 210 and the back panel 500 respectively.

[0141] [Actuator]

[0142] In some embodiments, the exciter 400 can be any one or more of an electromagnetic exciter, a magnetostrictive exciter, and a piezoelectric exciter, offering high applicability. In some embodiments, the exciter 400 may further include a magnetic field generating unit (e.g., a magnet) and a vibration coil. The magnetic field generating unit generates a magnetic field, and by inputting a constantly changing current into the vibration coil, the force exerted on the vibration coil in the magnetic field generated by the magnetic field generating unit changes continuously, thereby generating vibration.

[0143] Please continue to refer to Figures 2 to 5 In some embodiments of this application, the exciter 400 includes an exciter body 410.

[0144] In some embodiments, the actuator 400 includes an actuator 420.

[0145] In some embodiments, the actuator 400 includes a spring 430 connected between the actuator body and the actuator 420.

[0146] In some embodiments, the actuator 420 is connected to the sound-emitting plate 600 as an actuator. When the exciter 400 is activated, the actuator 420 vibrates and drives the sound-emitting plate 600 to vibrate, and transmits the vibration to the lamp plate 210. The vibration of the lamp plate 210 is transmitted to the optical film assembly 110 and the display panel 100 through the gas gap between the lamp plate 210 and the optical film assembly 110, so as to drive the display panel 100 to vibrate and produce sound.

[0147] Understandably, the spinner 430 can increase the heat dissipation path of the exciter 400, reduce the local temperature of the display panel 100 that emits sound, avoid the appearance of "hot spots" on the display panel 100, avoid uneven screen brightness and color, and increase the maximum power and operational reliability of the exciter 400.

[0148] The thermal conductivity of the spring wave 430 in this embodiment is several times that of ordinary metal materials such as copper and aluminum, so that the heat of the actuator 420 can be mainly transferred to the exciter body 410 through the spring wave 430, thereby reducing the temperature of the vibration output end of the actuator 420 and reducing the impact of local temperature on the image display quality of the display device.

[0149] In some embodiments, the actuator body 410 may include a housing 411.

[0150] In some embodiments, the actuator body 410 may include a magnet 412.

[0151] One end of the spinneret 430 is bonded to the magnetic conductor 412, which is connected to the outer shell 411, thereby transferring heat to the outer shell 411 through the magnetic conductor 412 and improving heat dissipation efficiency.

[0152] Figure 9 This is a partial cross-sectional view of a spider in a display device according to some embodiments of this application. Figure 10 This is a cross-sectional view of the end of the spring in a display device according to some embodiments of this application.

[0153] In some embodiments, please refer to Figure 9 and Figure 10 and combined Figures 2 to 5 The spindle 430 may include a heat-conducting layer 431.

[0154] In some embodiments, the spring 430 may include a fabric layer 432, which is stacked with a thermally conductive layer 431; the thermally conductive layer 431 at the end of the spring 430 is at least partially exposed so that the thermally conductive layer 431 contacts the magnetic conductor 412, thereby improving the efficiency of heat conduction of the spring 430 while ensuring that the spring 430 has good elasticity.

[0155] In some embodiments, the actuator 400 may further include a pressure ring 440 connected between the housing 411 and the magnetic conductor 412; at least a portion of the structure of the pressure ring 440 abuts against the end of the spring 430. This can improve the installation reliability of the spring 430.

[0156] Among them, the pressure ring 440 can be a heat-conducting metal material, used to press the spring 430, so that the heat-conducting layer 431 of the outer ring of the spring 430 is partially exposed on one side and in close contact with the magnetic conductor 412.

[0157] For example, the contact points between the spring 430 and the actuator 420 can be bonded with adhesive. The contact points between the spring 430 and the magnetic conductor 412, as well as the contact points with the pressure ring 440, can also be bonded with adhesive.

[0158] For example, the heat-conducting layer 431 may include a heat-conducting film with multiple openings to improve the heat conduction efficiency of the heat-conducting layer 431. The fabric layer 432 may be a fiber fabric, including but not limited to mesh fabric, fiberglass mesh fabric, etc., and is subjected to resin impregnation and curing treatment. The heat-conducting film may be a graphene film, prepared by using flake graphite as raw material through processes such as oxidation to form graphene oxide slurry, coating to form a film, sintering reduction, and calendering.

[0159] One possible manufacturing process for Tamper 430 includes: on the one hand, using flake graphite as raw material, performing oxidation and slurry preparation processes to form graphene oxide slurry; then coating it into a base film, followed by sintering, reduction, and calendering processes to form a graphene film; on the other hand, using fiber mesh cloth as raw material, impregnating the fiber mesh cloth in resin to form a fiber film; finally, stacking the graphene film and the fiber film, embossing it into a wavy shape, and after curing, forming Tamper 430 with high thermal conductivity.

[0160] The spring wave 430 of this application embodiment uses a fabric layer 432 as a skeleton and is formed by combining the fabric layer 432 and the heat-conducting layer 431. It not only has elasticity but also high thermal conductivity, which is beneficial for transferring the heat generated by the actuator 420 to the outer shell 411, thereby reducing the heat generated by the actuator 420 from being transferred to the display panel.

[0161] In some embodiments, the thickness of the thermally conductive film is greater than or equal to 100 μm and less than or equal to 1000 μm. Specific thickness values ​​that can be used for the thermally conductive film include 100 μm, 101 μm, 200 μm, 500 μm, 900 μm, 999 μm, and 1000 μm; this application does not impose specific limitations on these values.

[0162] In some embodiments, the thermally conductive layer 431 contacts the outer casing 411, thereby improving heat transfer efficiency and thus improving the heat dissipation efficiency of the actuator 420. When the thermally conductive layer 431 is located on at least one surface of the spring 430, the surface directly contacts the outer casing 411; when the thermally conductive layer 431 is located in the inner layer of the spring 430, for example, when the thermally conductive layer 431 is located between two fabric layers 432, the fabric layer 432 of the spring 430 facing the outer casing 411 is provided with a notch, so that the thermally conductive layer 431 is disposed on the surface of the spring 430 and thus contacts the outer casing 411. The fabric layer 432 corresponding to the spring 430 is provided with a notch, so that the thermally conductive layer 431 is disposed on the surface of the spring 430 and the surface contacts the outer casing 411.

[0163] It is understandable that the thermal conductive layer 431 can directly contact the outer casing 411, or the thermal conductive layer 431 can indirectly contact the outer casing 411 through other components.

[0164] Figure 11 This is a schematic diagram of the compression of the spring in the display device of some embodiments of this application. Figure 1 , Figure 12 This is a schematic diagram of the compression of the spring in the display device of some embodiments of this application. Figure 2 .

[0165] Please refer to Figure 11 In some embodiments, the fabric layer 432 is two layers, with the heat-conducting layer 431 sandwiched between the two fabric layers 432. Please refer to... Figure 12 In other embodiments, the thermally conductive layer 431 consists of two layers, with a fabric layer 432 sandwiched between the two thermally conductive layers 431. This creates a sandwich structure, improving the structural reliability of the spindle 430.

[0166] In some embodiments, the portion of the magnetic conductor 412 that contacts the spring 430 is provided with ventilation holes to improve the heat dissipation efficiency of the magnetic conductor 412 and increase the heat dissipation of the actuator 420 through the spring 430. The ventilation holes can be circular holes, and the embodiments of this application do not limit the shape, number, or arrangement of the ventilation holes.

[0167] In some embodiments, a vent is provided at the portion of the housing 411 that contacts the magnetic conductor 412. The vent can be opposite to the ventilation hole to further improve heat dissipation efficiency. The vent can be a circular hole, and the shape, number, and arrangement of the vent are not limited in the embodiments of this application.

[0168] In some embodiments, the housing 411 of the actuator 400 is connected to the back plate 500 by a fixing pin, which may be perpendicular to the back plate 500. An elastic pad is provided on the housing 411, and the housing 411 is connected to the back plate 500 by the elastic pad.

[0169] The elastic pad can be made of silicone, rubber, etc. The elastic pad can be sleeved on the outside of the fixing pin. The outer shell 411 is provided with a mating hole, and the outer wall of the elastic pad is provided with a snap-fit ​​groove that snaps into the outer shell 411. In this way, there are partial elastic pads on both sides of the mating hole, that is, the cross-sectional shape of the elastic pad can be approximately I-shaped, so as to avoid interference between the outer shell 411 and the fixing pin or the back plate 500 during the vibration of the exciter 400. This embodiment does not limit the structure, material, etc. of the elastic pad.

[0170] In some embodiments of this application, a support member 300 may be provided between the lamp panel 210 and the optical film assembly 110. The first end of the support member 300 may be connected to the lamp panel 210, and the second end of the support member 300 may abut against the optical film assembly 110.

[0171] Understandably, the support 300 can be placed between the lamp panel 210 and the optical film assembly 110 to prevent collisions or friction with the optical film assembly 110 during backlight vibration, thereby avoiding noise.

[0172] It should be noted that the support component 300 can be connected to the lamp panel 210 by means of bonding, snap-fit, or bonding to the encapsulation material of the light source. To facilitate the scattering of light from the light source, the interior of the support component 300 can be filled with air bubbles, silicone, etc.

[0173] In some embodiments, the cross-sectional dimensions of the support 300 may gradually decrease from one end of the light source to one end of the optical film assembly 110, i.e., the support 300 is approximately conical. The outer wall surface of the support 300 may also be convex to allow the light emitted from the light source to undergo total internal reflection within the support 300. In addition, an optical material may be coated on the outer wall surface of the support 300, such as an elastic silicone layer, to allow the light emitted from the light source to undergo total internal reflection within the support 300 or for only a portion of the light to exit through the side wall surface of the support 300.

[0174] It is understandable that the support member 300 can be sandwiched between the optical film assembly 110 and the lamp plate 210. That is, under normal conditions, the support member 300 is in a compressed state, and when the exciter 400 drives the lamp plate 210 to vibrate back and forth, the support member 300 will extend and retract accordingly, and will not separate from the optical film assembly 110 or the lamp plate 210, so as to avoid vibration transmission failure.

[0175] For example, the height of the support member 300 in its natural state is greater than the gap between the gases in the gas layer M and less than the sum of the amplitude of the exciter 400 and the gap between the gas layer M. For instance, the height of the support member 300 in its natural state can be half the amplitude of the exciter 400 and the sum of the gap between the gas layer M.

[0176] In some embodiments, there can be multiple support members 300, and each lamp panel 210 can be provided with multiple support members 300. The exciter 400 can be located at the center of the corresponding lamp panel 210. Multiple support members 300 can be distributed in an array around the exciter 400. The support members 300 can evenly assist in the transmission of vibration of the exciter 400. That is, each area where the support members 300 are distributed can have components that assist in the transmission of vibration. The even distribution of the support members 300 makes the overall force of the display device more balanced and improves the sound effect.

[0177] It should be noted that there can be multiple support members 300, and each lamp panel 210 can be provided with multiple support members 300. The exciter 400 can be set at the center of the corresponding lamp panel 210. Multiple support members 300 can be distributed in an array around the exciter 400. The support members 300 can evenly assist in the transmission of vibration of the exciter 400. That is, there can be components that assist in the transmission of vibration in each area where the support members 300 are distributed. The even distribution of the support members 300 makes the overall force of the display device more balanced and improves the sound effect.

[0178] The display device provided in this application can have various implementation forms, such as a television, a smart television, a monitor, an electronic bulletin board, an electronic table, etc.

[0179] Users can operate the display device via smart devices or control devices. In some embodiments, the display device also communicates with a server. The display device may be allowed to communicate via a local area network (LAN), wireless local area network (WLAN), and other networks. The server can provide various content and interactive features to the display device. The server can be a cluster or multiple clusters, and may include one or more types of servers.

[0180] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
