Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a display device. Background Art

[0002] In the field of electronic devices, moisture has long been considered a natural enemy to their performance and lifespan. Moisture intrusion into electronic devices can not only cause circuit shorts but also lead to corrosion of electronic components and other problems. This impact is particularly pronounced for delicate and critical components like displays, often directly damaging the display. Therefore, the development and application of waterproofing technology is particularly important in display manufacturing.

[0003] In related technologies, waterproof display designs primarily utilize various technologies, including sealing structures, waterproof coatings, and waterproof interfaces, to effectively block water intrusion. These designs not only protect the display's internal circuits and electronic components from moisture but also prevent moisture in humid environments, thereby preventing problems such as wire aging and connector damage caused by excessive humidity. This design enables waterproof displays to maintain excellent performance in a variety of harsh environments, significantly reducing failure rates and increasing device reliability and service life.

[0004] However, despite the remarkable waterproof performance of these displays, their design still presents some significant drawbacks. Currently, mainstream waterproof displays on the market mostly utilize a glass cover and optically clear adhesive (OCA), or simply waterproof adhesive. While the glass cover provides some protection, it also increases the weight of the display, compromising portability and potentially making installation and use more inconvenient.

[0005] Furthermore, the glass cover can affect display brightness and even cause color distortion, reducing the user's visual experience. More importantly, over long-term use, the adhesive used for bonding can age easily, rendering the waterproofing ineffective. This not only shortens the display's lifespan but can also pose a safety hazard.

[0006] Therefore, how to achieve a lighter, more efficient and longer-lasting waterproof effect for displays is an urgent problem to be solved. Summary of the Invention

[0007] The present application provides a display device that can achieve a lighter, more efficient and more durable waterproof effect.

[0009] In one possible embodiment, the first supporting portion includes a second cover plate, a first side plate, a second side plate, and two third side plates, wherein the first side plate, one of the third side plates, the second side plate, and the other of the third side plates are sequentially connected and are all connected to the second cover plate, so that the first side plate, the second cover plate, the second side plate, and the third side plates are enclosed to form the first receiving groove; The first side plate and the third side plate are respectively welded to the first shielding portion, and the second side plate and the third side plate are respectively welded to the second surface of the first cover plate.

[0010] In a possible implementation, the first support portion is an integrally formed structure.

[0011] In a possible implementation manner, the first side plate, the second side plate, and the third side plate are respectively welded to the second cover plate.

[0012] In a possible implementation, an annular protrusion is provided on the inner wall of the first accommodating groove, and the annular protrusion is sealed to the second cover plate.

[0013] In a possible implementation manner, the first support portion further includes a connecting member; and the annular protrusion is detachably connected to the second cover plate via the connecting member.

[0014] In a possible implementation, the first support portion further includes a sealing member; the sealing member is sandwiched between the annular protrusion and the second cover plate.

[0015] In a possible implementation manner, the second cover is made of any one of plastic, glass, and metal.

[0016] In a possible implementation, when the second cover plate is made of the metal material, the display device further includes a heat conduction structure, and the heat conduction structure is sandwiched between the display unit and the second cover plate.

[0017] In a possible implementation, the display unit includes a thin film crystal layer, a second shielding portion, a chip-on-film, a circuit board, a second supporting portion, a light-emitting portion, and at least one optical film layer; The second shielding portion is formed with a second accommodating groove, the light-emitting portion and the second supporting portion are respectively arranged on the bottom wall of the second accommodating groove, and the second supporting portion is used to support the optical film layer; The thin film crystal layer is connected to the second shielding portion to close the second receiving groove; The circuit board is arranged on a side of the second shielding portion away from the second accommodating groove, and the circuit board is connected to the thin film crystal layer through the chip-on-film.

[0018] According to the display device provided in the embodiment of the present application, the first cover plate serves as the glass cover plate, simplifying the overall structure of the display device and achieving a lightweight and thin design for the display device. Furthermore, the first cover plate and the base are laser welded to achieve a highly waterproof display design. This not only effectively reduces the weight increase caused by waterproof design in related technologies, but also avoids problems such as reduced display brightness and color effects. Furthermore, because the weld formed by laser welding has high strength and sealing properties, it can maintain a stable waterproof effect over a long period of time, thereby avoiding the problem of waterproof failure caused by glue aging.

[0025] First embodiment In this embodiment, if Figure 1 As shown, a display device includes a display unit 1, a first cover plate 2 and a base 3.

[0026] The first cover plate 2 has a first surface 21 and a second surface 22 disposed opposite each other along its thickness. The first cover plate 2 is, for example, a color filter (CF), an optical filter that precisely selects and transmits light of specific wavelengths. For example, the color filter layer includes a glass substrate, a black matrix, a color layer, a protective layer, and an indium tin oxide (ITO) conductive film. The color layer is composed of precisely arranged pixels of the three primary colors of red (R), green (G), and blue (B), with each pixel corresponding to a set of RGB. The color filter layer selectively transmits the three primary colors of red, green, and blue light, and works with the liquid crystal layer to form a color display. The color filter layer can directly affect key display properties of the display device, such as color saturation, contrast, and viewing angle.

[0027] The base 3 is, for example, a glass back cover. The base 3 includes a first supporting portion 31 and a first shielding portion 32. The first supporting portion 31 is formed with a first accommodating groove 311. By accommodating the display unit 1 in the first accommodating groove 311, a smooth appearance can be achieved and the display unit 1 can be effectively protected.

[0028] The first shielding portion 32 is, for example, a front bezel, made of glass. The cross-sectional dimensions of the first shielding portion 32 are smaller than those of the first cover plate 2, and a portion of the first shielding portion 32 covers the first cover plate 2. Specifically, one side of the first shielding portion 32 is laser-welded to the first support portion 31. Laser welding fuses the glass at the joints to form a single piece, ensuring a secure connection. The other side of the first shielding portion 32 is welded to the first surface 21 of the first cover plate 2, while the second surface 22 of the first cover plate 2 is welded to the first support portion 31. The first shielding portion 32 and the first cover plate 2 are joined together to seal the first accommodating groove 311.

[0029] Since laser welding can melt the glass materials together to form a whole, this connection method can effectively isolate moisture, achieve sealing and high waterproof performance. Good sealing performance can protect the display unit 1 from moisture and dust, thereby extending the service life of the display device.

[0030] The display device of this embodiment utilizes a color filter layer as the first cover plate 2 and a glass back cover as the base 3, and incorporates laser welding technology to achieve a smooth appearance, excellent display performance, and high waterproof performance. This display device is suitable for various electronic devices requiring high-quality display and waterproof performance.

[0031] In this embodiment, if Figure 1 As shown, the first support portion 31 includes a second cover plate 314, a first side plate 312, a second side plate 313, and two third side plates (not shown). The first side plate 312, one of the third side plates, the second side plate 313, and the other third side plate are sequentially connected to form a surrounding structure. At the same time, the first side plate 312, the third side plate, and the second side plate 313 are all connected to the second cover plate 314, so that the first side plate 312, the second cover plate 314, the second side plate 313, and the third side plates enclose and form a first receiving groove 311. The first receiving groove 311 is used to accommodate the display unit 1 to achieve a smooth appearance and protect the display unit 1.

[0032] The first side panel 312 and the third side panel are respectively welded to the first shielding portion 32, while the second side panel 313 and the third side panel are respectively welded to the second surface 22 of the first cover plate 2. This welding method ensures a secure connection between the components while also providing a good seal. The first side panel 312 is larger than the second side panel 313 along the thickness of the display device, for example, to form a partially outwardly flared shape, thereby providing clearance for the display unit 1.

[0033] For example, the second cover plate 314 is welded to the first side plate 312, the second side plate 313 and the two third side plates respectively, which can further improve the reliability of the connection and have high waterproof performance, effectively protecting the display unit 1 from moisture and dust. Or, The first support portion 31 is an integrally molded structure, i.e., a one-piece glass back cover is used. This simplifies the manufacturing process, improves production efficiency, simplifies production steps, and thus reduces production costs. Furthermore, the one-piece molded structure also provides excellent sealing performance and mechanical strength, meeting the requirements of display devices.

[0034] The display device of this embodiment utilizes a color filter layer as the first cover plate 2 and a glass back cover as the base 3, combined with the structure of the first support portion 31 and welding technology, to achieve the advantages of a smooth appearance, excellent display performance, and high waterproof performance. This display device is suitable for various electronic devices requiring high-quality display and waterproof performance. The first cover plate 2 and the first shielding portion 32 act as covers to enclose the first accommodating groove 311. Compared with waterproof displays in related technologies, this application further optimizes the overall structure of the display device, achieving a lightweight and thin design of the display device.

[0035] In this embodiment, if Figure 1 As shown, the display unit 1 includes a thin film crystal layer 11 , a second shielding portion 12 , a chip on film (COF) 13 , a circuit board 14 , a second supporting portion 15 , a light emitting portion 16 and at least one optical film layer 17 .

[0036] The thin film crystal layer 11 typically includes a thin film transistor (TFT) array for controlling display pixels. The thin film crystal layer 11 is connected to the second shielding portion 12 , together forming the basic structure of the display unit 1 . The thin film crystal layer 11 encloses the second receiving groove 121 .

[0037] The second shielding portion 12 is formed with a second receiving groove 121 for accommodating the light emitting portion 16, the second supporting portion 15 and possibly other components. As a main supporting and protective structure of the display unit 1, the second shielding portion 12 ensures the stability and safety of the internal components.

[0038] The light-emitting portion 16 and the second support portion 15 are respectively disposed on the bottom wall of the second accommodating groove 121, and the second support portion 15 is used to support the optical film layer 17. The light-emitting portion 16, for example, includes a plurality of lamp beads 161, which are arranged on the bottom wall of the second accommodating groove 121. The lamp beads 161 are the light source of the display unit, which is used to emit light to realize the display function. The second support portion 15, for example, includes a plurality of support columns 151, which are arranged on the bottom wall of the second accommodating groove 121 to support the optical film layer 17 and ensure an appropriate distance and stability between the optical film layer 17 and the light-emitting portion 16. The support columns 151 are designed to avoid interference with the lamp beads 161 to avoid interfering with the lighting effect.

[0039] The optical film layer 17 may be at least one layer, or may be multiple layers, stacked sequentially. The optical film layer 17 may include, but is not limited to, a diffusion film, a brightness enhancement film, etc., and is used to improve the quality of light emitted by the light-emitting portion 16. The optical film layer 17 is supported by the second support portion 15 to ensure a stable relative position between the optical film layer 17 and the light-emitting portion 16.

[0040] The circuit board 14 is disposed on the side of the second obstructing portion 12 facing away from the second receiving groove 121. The circuit board 14 is connected to the thin-film crystal layer 11 via the chip-on-film 13 to enable electrical signal transmission. The circuit board 14 is electrically connected to the light-emitting portion 16. The circuit board 14 serves as the electrical control center of the display unit 1, receiving and processing external signals and transmitting them to the thin-film crystal layer 11 via the chip-on-film 13.

[0041] The display device provided in this embodiment utilizes the first cover plate 2 as a glass cover plate, simplifying the overall structure of the display device and achieving a lightweight and thin design. Furthermore, the first cover plate 2 and the base 3 are laser welded to achieve a highly waterproof display design. This not only effectively reduces the weight increase associated with waterproofing, but also avoids issues such as reduced display brightness and color degradation. Furthermore, because the weld seam formed by laser welding has high strength and sealing properties, it can maintain a stable waterproof effect over a long period of time, thus avoiding waterproofing failure caused by glue aging.

[0042] Second embodiment The second embodiment of the present application further provides a display device, which has the same or similar structure as the display device provided in the first embodiment, except that: Figure 2As shown, the base 3 has a split structure, which enhances the reworkability of the display device's internal structure and greatly facilitates operations such as assembly, disassembly, and maintenance of internal electronic components. For example, the first side panel 312, the second side panel 313, and the third side panel are each detachably connected to the second cover panel 314, facilitating subsequent maintenance. This detachable connection not only simplifies the assembly process but also allows for faster and more convenient repairs or component replacements, thereby reducing maintenance costs and improving efficiency.

[0043] In this embodiment, the inner wall of the first receiving groove 311 is provided with an annular protrusion 3111, and the annular protrusion 3111 is sealed with the second cover plate 314. That is, the annular protrusion 3111 is arranged around the first side plate 312, the second side plate 313 and the third side plate.

[0044] A concave space is formed between the annular protrusion 3111 and the bottom of the first accommodating groove 311 , and the space can accommodate the edge portion of the second cover plate 314 , thereby achieving a tight fit between the second cover plate 314 and the base 3 .

[0045] During assembly, the second cover plate 314 is nestled between the annular protrusion 3111 and the first receiving groove 311. The annular protrusion 3111 and the second cover plate 314 are in surface-to-surface contact, while the sidewalls of the second cover plate 314 also adhere to the inner walls of the first receiving groove 311. This double-fit design not only ensures a tight seal but also enhances structural stability. To ensure the flatness of the back of the display device, the thickness of the second cover plate 314 is the same as the depth of the recess formed between the annular protrusion 3111 and the first receiving groove 311. This ensures that the back of the display device maintains a flat surface after assembly.

[0046] Furthermore, annular protrusion 3111 increases the contact area with second cover plate 314, further enhancing sealing capabilities and effectively preventing external impurities such as dust and moisture from entering the display device. Furthermore, annular protrusion 3111 provides support for second cover plate 314, enhancing the stability and durability of the entire structure.

[0047] In this embodiment, the first support portion 31 further includes a connector 316, and the annular protrusion 3111 is detachably connected to the second cover plate 314 via the connector 316. For example, the connector 316 includes a plurality of bolts, which are sequentially arranged along the circumference of the annular protrusion 3111, thereby ensuring uniform force and reliability when the annular protrusion 3111 and the second cover plate 314 are connected.

[0048] To further enhance the display device's waterproof performance, a blind hole design is used for the bolt mounting location on the annular protrusion 3111. A blind hole is a hole with only one end open and the other closed. This design effectively prevents moisture from entering the display device through the bolt mounting hole, thereby enhancing the display device's sealing and waterproof capabilities.

[0049] During assembly, one end of the bolt rotatably passes through the corresponding hole in the second cover plate 314 and then screws into the blind hole in the annular protrusion 3111. This connection not only ensures a secure connection between the annular protrusion 3111 and the second cover plate 314, but also, due to the design of the blind hole, prevents moisture from penetrating into the display device through the bolt mounting hole, thereby ensuring the safe and stable operation of the display device's internal electronic components.

[0050] In this embodiment, to further enhance the sealing performance of the display device, the first support portion 31 further includes a seal 315. The seal 315 is sandwiched between the annular protrusion 3111 and the second cover plate 314. This design allows the seal 315 to fit tightly against the contact surface between the annular protrusion 3111 and the second cover plate 314, thereby effectively preventing external impurities such as dust and moisture from entering the interior of the display device.

[0051] The seal 315 , such as a rubber ring, has good elasticity and sealing performance, and can fit tightly against the contact surface when compressed to form an effective seal. Furthermore, the rubber ring has certain wear resistance and corrosion resistance, and can maintain stable sealing performance during long-term use.

[0052] During assembly, seal 315 is first placed on annular protrusion 3111, then second cover plate 314 is installed. Connectors 316 (e.g., bolts) secure annular protrusion 3111 and second cover plate 314 together. During this process, seal 315 is tightly clamped between annular protrusion 3111 and second cover plate 314, creating a reliable seal.

[0053] To prevent seal 315 from being misaligned or offset during installation, a groove is provided at the corresponding position of annular protrusion 3111 and second cover plate 314, allowing seal 315 to fit into the groove. The depth of the groove is less than the outer diameter of seal 315, ensuring that seal 315 can protrude, fill the gap, and form an effective seal.

[0054] In this embodiment, the second cover plate 314 is made of glass, for example, which is consistent with the material of the first side plate 312, the second side plate 313, and the third side plate. This not only makes the base 3 have good transparency and hardness, effectively displaying the electronic components inside the display device, but also makes the base 3 more coordinated and beautiful in appearance due to its uniform material, improving the overall texture. In addition, the glass material is easy to clean and maintain, so that the display device can maintain a good appearance during use. Or, Considering the overall weight and waterproof performance of the display device, the second cover plate 314 is made of, for example, a plastic material. Plastic has advantages such as light weight, easy molding, low cost, and a certain degree of waterproof performance. Using a plastic second cover plate 314 can effectively reduce the overall weight of the display device, making it more convenient to carry and move. Furthermore, the waterproof performance of the plastic material can also prevent moisture from penetrating into the display device to a certain extent, thereby protecting the safety of the internal electronic components.

[0055] It should be noted that the first side panel 312 , the second side panel 313 and the third side panel are still made of glass material, so that they can be more easily integrated with the first cover panel 2 when welded, reducing the welding difficulty, improving the welding effect, and ensuring the structural strength and stability of the base 3 .

[0056] The display device provided in this embodiment utilizes a split-structure base 3, a detachable connection method, and a sealing design comprising an annular protrusion 3111, a connector 316, and a seal 315. This not only improves the ease of assembly, disassembly, and maintenance of the display device, but also enhances its sealing performance and structural stability, effectively ensuring the normal operation of the display device. Furthermore, the second cover 314 can be made of various materials, such as glass or plastic, depending on actual needs. Changing the material of parts of the base 3 further reduces costs and weight, thereby contributing to a thinner and lighter design for the display device.

[0057] Third embodiment The third embodiment of the present application further provides a display device, which has the same or similar structure as the display device provided in the second embodiment, except that: Figure 3 As shown, the second cover plate 314 is made of a metal material, such as aluminum (Al) or copper (Cu), which has excellent thermal conductivity and helps to quickly dissipate heat from within the display device. The display device also includes a heat conduction structure 4, which is sandwiched between the second shielding portion 12 of the display unit 1 and the second cover plate 314. This allows heat generated by the light-emitting portion 16 to be efficiently dissipated through the heat conduction structure 4.

[0058] The heat conduction structure 4 may include, for example, a plurality of heat pipes or heat spreaders and other efficient heat dissipation elements. These elements utilize the phase change principle to dissipate heat and can transfer a large amount of heat under a very small temperature difference, thereby ensuring the stability of the internal temperature of the display device.

[0059] When the light-emitting portion 16 utilizes high-efficiency light-emitting components such as MiniLED or MicroLED light panels, it generates a significant amount of heat. This heat is transferred to the second cover plate 314 via the heat-conducting structure 4, where it then exchanges heat with the air, effectively dissipating the internal heat. This efficient heat dissipation design reduces damage to components and diaphragms caused by excessive internal temperatures, improving the reliability and lifespan of the display device. Because the second cover plate 314 is made of metal and combined with the design of the heat-conducting structure 4, a highly waterproof design can be achieved while maintaining heat dissipation performance.

[0060] The display device provided in this embodiment utilizes a metal second cover plate 314 and a heat-conducting structure 4 to efficiently dissipate heat from the display device and enhance its waterproof performance. This design not only increases the reliability and service life of the display device but also expands its application scenarios, enabling stable operation in more complex environments.
