Description

Technical Field

[0001] This invention belongs to the field of home appliance technology, specifically, it relates to a display device and a home appliance. Background Technology

[0002] With the rapid development of technology and the increasing intelligence of home appliances, users have placed higher demands on the display effects and user experience of these devices. In the field of home appliance display technology, LCD screens and color filter backlighting solutions are currently the two mainstream choices in the market, but each has significant limitations and cannot meet the market's pursuit of high-quality display effects.

[0003] LCD screens are widely used in home appliances due to their advantages such as high resolution, rich colors, and wide viewing angles. However, a significant drawback of this solution is its high cost. The production of LCD screens involves complex manufacturing processes and sophisticated circuit designs, which not only drives up manufacturing costs but also increases circuit complexity, posing a potential threat to product reliability. LCD display solutions face enormous challenges in both cost control and reliability improvement.

[0004] Compared to LCD screens, color filter backlighting offers a cost advantage, making it suitable for cost-sensitive markets. However, this solution has significant shortcomings in display quality. Due to tiny gaps in the assembly process between the light source and the color filter, and between the color filter and the user's viewing screen, these gaps cause scattering and reflection during light propagation, resulting in a "foggy" effect on the displayed image—the so-called "fog screen" phenomenon. This display effect not only reduces image clarity and contrast but also severely impacts the user's visual experience.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a display device and home appliance that prevents light from leaking from the gap between the decorative components and the light source components, thereby improving the overall visual effect and user experience.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] A display device, comprising:

[0009] Display panel bracket;

[0010] Decorative components are mounted on one side of the display panel bracket;

[0011] A light source assembly with a light-emitting area is located on the other side of the display panel bracket, with a gap between it and the decorative assembly;

[0012] A filling component is disposed within the gap, at least surrounding the periphery of the light-emitting area.

[0013] Furthermore, the two sides of the filling component are respectively attached to the decorative component and the light source component.

[0014] Furthermore, the light-emitting area has multiple spaced light source chambers, and the filling component is disposed on the periphery of the light-emitting area and at the interval between two adjacent light source chambers.

[0015] Furthermore, the filling component covers the light-emitting area and has openings that correspond one-to-one with the light source chambers, through which light from the light source chambers is projected onto the decorative component.

[0016] Furthermore, the light source assembly has a lamp holder and a light-emitting element;

[0017] The light source cavity is disposed on the lamp holder and is a recessed structure formed by the side of the lamp holder facing the display panel support; the light-emitting element is installed in the light source cavity;

[0018] Preferably, the light-emitting element is disposed on the light source circuit board, the light source chamber has a channel passing through both sides of the lamp holder, the light source circuit board is installed on the side of the lamp holder facing away from the display panel bracket, and the light emitted by the light-emitting element passes through the channel and is projected onto the decorative component.

[0019] Furthermore, the filling component extends along the length direction and / or width direction of the decorative component or the light source component.

[0020] Furthermore, the filling component is made of a flexible material, and the decorative component and the light source component deform the filling component by pressing it from both sides;

[0021] Preferably, the flexible material is foam.

[0022] Furthermore, the filling component is bonded to the light source component, the decorative component is mounted on the display panel bracket, and the filling component is squeezed to deform in all directions.

[0023] Furthermore, a display film with display content is attached to the side of the decorative component facing the light source component;

[0024] Preferably, the display film is an integrated color film with touch display function.

[0025] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0026] In this invention, by setting a filling component within the gap formed by the installation of the decorative component and the light source component, the problem of light source management is effectively solved, ensuring the orderly propagation and distribution of light, avoiding the negative impact of light leakage on user experience, thereby improving the overall visual effect and user experience. Simultaneously, by reducing light overflow, the display brightness of the display device is improved, ensuring clear visibility of screen content and further enhancing the user's visual experience.

[0027] In this invention, by using foam as a filling component, the display device effectively solves the problem of light leakage and improves light utilization efficiency. Simultaneously, the application of an integrated color film as the display film not only enhances the touch functionality of the display device but also improves its visual effects and user experience. The combination of the light-emitting element and the lamp holder ensures the stability and reliability of the light source. The entire device has a compact structure and complete functions, providing users with a clear and comfortable visual experience and convenient touch operation.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0037] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] Currently, in commonly used color filter backlight display solutions, there are tiny gaps caused by the assembly process between the light source and the color filter, and between the color filter and the display screen seen by the user. These gaps cause scattering and reflection during light propagation, resulting in a "foggy" effect on the image observed by the user, also known as the "fog screen" phenomenon. This display effect not only reduces the clarity and contrast of the image, but also seriously affects the user's visual experience.

[0039] Example 1

[0040] To solve the above problems, such as Figures 1 to 3 As shown, this embodiment provides a display device, including:

[0041] Display panel bracket 1;

[0042] Decorative component 2 is installed on one side of display panel bracket 1;

[0043] A light source assembly 3 with a light-emitting area is disposed on the other side of the display panel bracket 1, and has a gap 4 between it and the decorative assembly 2;

[0044] The filling component 5 is disposed within the gap 4, at least surrounding the periphery of the light-emitting area.

[0045] In this embodiment, the decorative component 2 is attached to one side of the display panel bracket 1. The decorative component 2 is used to enhance the overall aesthetics and visual appeal of the device. The decorative component 2 may include various design elements, such as textures, colors, patterns, or brand logos, to enhance the uniqueness of the device. The decorative component 2 can be made of transparent material or other materials that can display content.

[0046] In this embodiment, the light source assembly 3 is disposed on the other side of the display panel bracket 1, and after installation with the decorative assembly 2, there is a certain gap 4 between them. The light source assembly 3 is a key component for providing light output and has a light-emitting area that may include LEDs or other types of lighting elements. These light sources are used to illuminate the display content on the display panel bracket 1 and enhance the visual effect.

[0047] In this embodiment, the filling component 5 is disposed within the gap 4 between the light source component 3 and the decorative component 2, and at least surrounds the periphery of the light-emitting area. Its main function is to block the light emitted by the light source component 3 from overflowing to the outer periphery of the light-emitting area. Since the light source component 3 may produce light overflow or scattering when emitting light, if not controlled, it may affect the visual effect or cause light pollution and discomfort to the user.

[0048] Furthermore, the filling component 5, through its specific materials and structure, such as light-absorbing materials and reflective materials, effectively limits the diffusion range of light to optimize the propagation and distribution of light, ensuring no light leakage, thereby improving the overall visual effect and user experience.

[0049] Furthermore, the two sides of the filling component 5 are respectively attached to the decorative component 2 and the light source component 3, ensuring that the filling component 5 can tightly seal the gap 4 and prevent light from leaking out of the gap 4.

[0050] In the above solution, a perfect combination of aesthetics and functionality is achieved through the rational layout and component selection of the display device. By setting a filling component 5 within the gap 4 formed by the installation of the decorative component 2 and the light source component 3, the problem of light source management is effectively solved, ensuring the orderly propagation and distribution of light, avoiding the negative impact of light leakage on the user experience, thereby improving the overall visual effect and user experience. At the same time, by reducing light leakage, the display brightness of the display device is improved, ensuring that the screen content is clearly visible, further enhancing the user's visual experience.

[0051] Example 2

[0052] This embodiment is a further description of Embodiment 1 described above.

[0053] like Figures 1 to 3As shown, in this embodiment, the decorative component 2 is disposed on the front of the display panel bracket 1, that is, the side directly facing the user or the side where the user operates. The light source component 3 is disposed opposite to the decorative component 2 and is installed on the back of the display panel bracket 1.

[0054] The gap 4 is the space formed between the light source component 3 and the decorative component 2 after they are assembled with the display panel bracket 1. Some light will leak out from the gap 4, causing light scattering or light pollution. The filling component 5 mainly functions to block the light leaking out of the light source component 3, ensuring that the light can propagate to the front of the display panel bracket 1 along a predetermined path, thus avoiding light pollution or visual interference caused by light leakage.

[0055] In this embodiment, the display panel bracket 1 serves as a supporting structure, and its core component is a frame structure. The display panel bracket 1 has a large-area through-structure corresponding to the light-emitting area of ​​the light source component 1. The decorative component 2 is installed on one side of the through-structure, and the light source component 1 is installed on the other side of the through-structure. The light emitted from the light-emitting area passes through the through-structure of the display panel bracket 1 and is projected onto the decorative component 2.

[0056] The aforementioned structural design not only ensures a balanced distribution of support forces but also fully considers ease of installation and stability. The frame is typically made of high-strength materials to ensure good stability and durability during long-term use.

[0057] Furthermore, decorative component 2 is tightly connected to the frame structure using screws, clips, etc., and is installed on the front of the frame structure to ensure it is stable and will not fall off. Light source component 3 is connected to the back of the frame structure using screws, etc., to ensure the stability of the display device.

[0058] Furthermore, the material of the filling component 5 should have good light-blocking and durability, while also possibly having a certain degree of flexibility and elasticity to adapt to changes in the size and shape of the gap 4. Its structure should fit tightly into the gap 4, leaving no gaps for light leakage.

[0059] In a further embodiment, the light-emitting area of ​​the light source assembly 3 has a plurality of spaced light source chambers 33, and the filling assembly 5 is disposed on the periphery of the light-emitting area and at the interval between two adjacent light source chambers 33.

[0060] Specifically, the space within the light-emitting area is divided into multiple independent light source chambers 33. These chambers can be regular or irregular in shape, depending on the design of the light source assembly 3.

[0061] The periphery of the light-emitting area composed of all the light-emitting chambers 33 and the decorative component 2 have gaps after installation, and there are also gaps 4 between the intervals between adjacent light-emitting chambers 33 and the decorative component 2. These gaps 4 are channels for light to scatter or overflow from the light-emitting chambers 33, and also serve as the installation positions for the filling components 5. The filling components 5 are disposed within the gaps 4, tightly fitted to the periphery of the light-emitting chambers 33 or between the intervals and the decorative component 2, to block light overflowing from the light-emitting chambers 33.

[0062] Furthermore, the size and shape of the gap 4 may vary depending on the design of the light source chamber 33.

[0063] In the above solution, a filling component 5 is set in the gap 4 to reduce interference and scattering between light rays, avoid the negative impact of light leakage on user experience, and provide users with a clearer and more comfortable visual experience.

[0064] In this embodiment, the filling component 5 covers the light-emitting area and has openings that correspond one-to-one with the light source chamber 33. The light from the light source chamber 33 passes through the openings and is projected onto the decorative component 2.

[0065] Specifically, the filling component 5 has openings that match the light source chamber 33. This design ensures that light emitted from the light source chamber 33 can pass through these openings without obstruction and continue to propagate along a predetermined path. In this way, the light can be effectively directed to other parts of the display device, such as the decorative component 2, thereby presenting a clear and bright image.

[0066] In this embodiment, the extension direction of the gap 4 is consistent with the extension direction of the decorative component 2 or the light source component 3, which helps to ensure that light can propagate along a predetermined path and reduce the possibility of light leakage. At the same time, it makes the installation and positioning of the filling component 5 simpler and more precise.

[0067] like Figures 1 to 3 As shown, in this embodiment, the light source assembly 3 has a lamp holder 31 and a light-emitting element 32.

[0068] Specifically, the lamp holder 31 is a component of the light source assembly 3, responsible for fixing the light source assembly 3 to one side of the display panel bracket 1. The lamp holder 31 typically has a certain thickness and structural strength to ensure that the light source assembly 3 can be securely mounted on the display panel bracket 1. A gap 4 is formed between the lamp holder 31 and the decorative component 2, which provides space for the subsequent installation of the filler component 5.

[0069] The light-emitting element 32 refers to a component capable of emitting light, such as an LED. The light-emitting element 32 is disposed inside the lamp holder 31 and is protected and supported by the lamp holder 31. The light emitted by the light-emitting element 32 shines out through the opening of the filling component 5 to provide backlighting or illumination effects.

[0070] Furthermore, the light source chamber 33 is disposed on the lamp holder 31 and is a groove structure formed by the inward recess of the lamp holder 31 on the side facing the display panel support 1; the light-emitting element 32 is installed in the light source chamber 33.

[0071] Specifically, the lamp holder 31, as a supporting structure, not only supports the light-emitting element 32, but also has a recessed light source chamber 33 designed on its side facing the display panel bracket 1. This recessed design can effectively accommodate and protect the light source element, while also facilitating the directional propagation of light.

[0072] In this embodiment, the light-emitting element 32 is disposed on the light source circuit board 321, the light source chamber 33 has a channel passing through both sides of the lamp holder 31, the light source circuit board 321 is installed on the side of the lamp holder 31 facing away from the display panel bracket 1, and the light emitted by the light-emitting element 32 passes through the channel and is projected onto the decorative component 2.

[0073] Specifically, the light source circuit board 321 typically integrates LEDs or other types of light-emitting components, which can emit light of different colors through circuit control. The light source circuit board 321 is responsible for generating light to provide a light source for subsequent projection or illumination.

[0074] The light source chamber 33 has a channel running through both sides of the lamp holder 31. This channel allows light emitted from the light source circuit board 321 to pass through unobstructed and be projected onto the external target. The light source chamber 33 not only provides a mounting position for the light-emitting element 32, but also optimizes the light propagation path through its structural design, so that the light can be projected onto the decorative component 2 more concentratedly and evenly.

[0075] In the specific implementation process, when the light source circuit board 321 is activated and emits light, this light first propagates along the surface of the light source circuit board 321 and then enters the channel of the light source chamber 33. Inside the channel, the light may undergo optical processing such as reflection and refraction to enhance its directionality and brightness. Finally, the light passes through the channel and is projected onto the decorative component 2.

[0076] In this embodiment, the projection effect of light on the decorative component 2 depends on a variety of factors, including the light-emitting characteristics of the light source circuit board 321, such as color, brightness, and color temperature; the structural design of the light source chamber, such as channel shape and reflective surface material; and the material and surface treatment of the decorative component 2. By rationally designing these factors, rich visual effects and lighting functions can be achieved.

[0077] In this embodiment, the filling component 5 extends along the length direction and / or width direction of the decorative component 2 or the light source component 3.

[0078] Specifically, the filling component 5 extends along the length and / or width of the decorative component 2 or the light source component 3, so that the filling component 5 can cover the entire length or width of the gap 4 as needed, or cover both simultaneously. In this embodiment, the size and shape of the filling component 5 can be selected according to the actual size and shape of the light source component 3 and the decorative component 2, as well as the size of the gap 4. Furthermore, the number or density of the filling components 5 can be increased as needed to further improve the light management effect.

[0079] In the above design, the display device achieves a good balance between aesthetics and functionality. The extension direction of the gap 4 is consistent with that of the decorative component 2 or the light source component 3, making the light propagation more orderly; the two ends of the filling component 5 are connected to the decorative component 2 and the light source component 3 respectively, ensuring the tight sealing of the gap 4; and the extension of the filling component 5 along the length and / or width directions provides greater flexibility and adaptability. The entire device has a compact structure and complete functions, providing users with a comfortable, convenient, and visually excellent operating experience.

[0080] Example 3

[0081] This embodiment is a further description of the above embodiments one and two.

[0082] like Figures 1 to 3 As shown, in this embodiment, the filling component 5 is made of a flexible material, and the decorative component 2 and the light source component 3 deform the filling component 5 by squeezing it from both sides.

[0083] Preferably, the flexible material is foam 51.

[0084] Specifically, the filling component 5 uses flexible foam 51. Foam 51 has good elasticity and compressibility, allowing it to deform in all directions after compression and then quickly return to its original shape. It also has a certain light absorption and light-blocking capacity. The foam 51 is installed within the gap 4 between the light source component 3 and the decorative component 2. During installation, the foam 51 is compressed and deformed to tightly fill the gap 4, preventing light from escaping from it.

[0085] Furthermore, the filling component 5 is bonded to the light source component 3, and the decorative component 2 and the light source component 3 are installed on the display panel bracket 1, and the filling component 5 is squeezed to deform in all directions.

[0086] In the specific implementation process, when the decorative component 2 is installed on the display panel bracket 1, the filling component 5 in the gap 4 between the squeeze light source component 3 and the decorative component 2 will deform in all directions to fill the gap 4 and block the overflowing light.

[0087] Furthermore, a display film 6 with display content is attached to the side of the decorative component 2 facing the light source component 3.

[0088] Specifically, the display film 6 is adhered to the decorative component 2 on the side facing the light source component 3, ensuring there are no gaps between them, thus preventing light leakage or unwanted shadows. This tightness helps improve the uniformity and clarity of the overall visual effect.

[0089] Preferably, the display film 6 is an integrated color film 61 with touch display function.

[0090] Specifically, the display film 6 adopts an integrated color film 61 with touch display function. This color film not only has touch function, but can also display color images and text, improving the visual effect and user experience of the display device.

[0091] In this embodiment, the decorative component 2 is a decorative panel, and the integrated color film 61 is made of a transparent material. This material not only has excellent light transmission performance, allowing light to pass through freely, but also incorporates rich pattern designs without sacrificing visual clarity. This light transmission adds a sense of layering and visual depth to the decorative panel.

[0092] Furthermore, the display pattern is not limited to printing or engraving directly on the integrated color film 61 itself. More complex and varied visual effects can also be achieved by attaching other translucent patterns to the back of the integrated color film 61. This design allows the decorative panel to be customized and varied according to different application scenarios and needs.

[0093] Furthermore, the ingenious combination of touch circuitry and translucent patterns achieves a seamless integration of touch and display. Users can not only execute various commands by touching the patterns on the decorative panel, but also obtain feedback information by observing the changes in the patterns during the touch process. This intuitive interaction method not only enhances the interactivity between users and the product, but also transforms the decorative panel into a multifunctional platform integrating decoration, interaction, and information display.

[0094] In the above solution, by using foam 51 as the filling component 5, the display device effectively solves the problem of light leakage and improves light utilization efficiency. Meanwhile, the application of the integrated color filter 61 as the display film 6 not only enhances the touch functionality of the display device but also improves its visual effects and user experience. The combination of the light-emitting element 32 and the lamp holder 31 ensures the stability and reliability of the light source. The entire device has a compact structure and complete functions, providing users with a clear and comfortable visual experience and convenient touch operation.
