Description

Technical Field

[0001] This utility model relates to the field of display technology, and more specifically to a display device. Background Technology

[0002] The display mainly consists of a front shell, a back shell, a shielding structure, and an LCD screen. The shielding structure is composed of two pieces of glass of equal thickness with a layer of metal mesh sandwiched between them. The metal mesh extends out of the shielding structure and makes conductive contact with the surrounding metal (front shell and back shell) to achieve electromagnetic compatibility (EMC) shielding.

[0003] Displays used in environments such as vehicles and ships are often used in harsh environments with a lot of dust, high temperature, high humidity, acid and alkali, and they are also frequently subjected to strong vibration, bumps and impacts. Under such conditions, if there is no stable and reliable electrical connection between the shielding structure and the front and rear shells, the display screen inside the monitor can easily be damaged by electromagnetic interference, affecting normal operation, and in severe cases, causing screen distortion, black screen and other malfunctions. Utility Model Content

[0004] In view of this, the present invention provides a display device to solve the problem that the poor electrical connection reliability between the shielding structure and the housing in existing display devices makes the display screen susceptible to electromagnetic interference and damage, thus affecting normal operation.

[0005] In a first aspect, this utility model provides a display device, including a housing structure, a display structure, a shielding structure, a protective layer, and an elastic element. The housing structure includes an accommodating space with an opening on one side; the display structure is disposed within the accommodating space; the shielding structure is disposed on the side of the display structure near the opening, and the shielding structure has a metal lead-out end connected to the housing structure; the protective layer is disposed at least on the side wall of the shielding structure to surround the metal lead-out end of the shielding structure; the elastic element is disposed between the protective layer and the housing structure, and the elastic element has an elastic force that presses the protective layer when it is offset toward the housing structure.

[0006] In this invention, the display structure is housed within a metal outer shell. A shielding structure is installed at the opening of the outer shell to seal the space. The shielding structure is electrically connected to the outer shell via metal leads, providing external electromagnetic protection for the display structure. A protective layer covers the metal leads of the shielding structure to prevent damage. Simultaneously, the protective layer acts as an elastic element, pressing the shielding structure or the direct contact surface between the shielding structure and the display structure. This prevents damage to the metal leads when the elastic element is used to secure the shielding and display structures. The elastic element ensures the installation stability of components such as the shielding structure and display structure within the space, forming a stable and reliable low-impedance electrical connection path. This reduces the risk of electrical connection failure and shielding performance degradation due to external impacts, ensuring the electromagnetic protection performance and normal operation of the display device.

[0007] In one alternative embodiment, the display structure and the shielding structure are fitted together, and the projection sizes of the display structure and the shielding structure on the outer shell structure are the same.

[0008] In this invention, the display structure and the shielding structure are the same size and fit together perfectly. The end of the shielding structure away from the display structure is fixed to the outer shell structure. The sidewall is stably connected to the outer shell structure through a protective layer and elastic elements, thereby improving the stability of the display structure within the outer shell structure and preventing the display structure and shielding structure from shaking under external impact, which could cause electrical connection failure and ensure electromagnetic shielding performance.

[0009] In one alternative implementation, a protective layer is provided to cover the sidewalls of the display structure and the shielding structure.

[0010] In this invention, the protective layer completely covers the sidewalls of the shielding structure and the display structure to form an integral and planar contact surface, which can promote reliable contact with the elastic element, ensure protection at the connection between the display structure and the shielding structure, and further improve the stability of the electrical connection.

[0011] In one alternative implementation, the protective layer is an embossed tin-plated copper foil.

[0012] In this invention, the embossed tin-plated copper foil has good ductility and good coverage of the metal lead-out end of the shielding structure. The tin plating of the copper foil improves the conductivity. The embossing on the surface of the tin-plated copper foil increases the contact friction between the tin-plated copper foil and the metal lead-out end, the shielding structure, the side wall of the display structure, and the elastic element, which in turn improves the connection between the above structures, thereby improving the stability of the internal structure of the display device and ensuring electromagnetic protection performance.

[0013] In one alternative embodiment, the housing structure includes a drive plate and a front housing that are fixedly connected, with an opening formed on the front housing and disposed opposite to the drive plate.

[0014] In this invention, the outer shell structure surrounds the display structure and the shielding structure, leaving only an opening for the light path. The internal components of the display device are effectively protected within the outer shell structure, ensuring the reliability of the display device.

[0015] In one alternative embodiment, the housing structure further includes a connector threadedly connected to the drive plate and the front housing to secure the drive plate and the front housing.

[0016] In this invention, the threaded drive plate and the front housing have good stability and are easy to disassemble and fix.

[0017] In one optional embodiment, it further includes: a seal, which is disposed at the connection between the shielding structure and the housing structure and is electrically connected to the metal lead-out terminal of the shielding structure and the housing structure; the protective layer, the seal, the display structure and the housing structure together enclose and seal the accommodating space.

[0018] In this invention, the sealing element seals the part where the shielding structure contacts the outer shell structure, improving electrical connection performance and protecting internal components, ultimately achieving all-round electromagnetic shielding for the display structure.

[0019] In one alternative embodiment, the seal comprises an integrally molded annular conductive foam.

[0020] In this invention, the conductive foam material is soft, which helps to protect the metal leads and ensures effective contact with the outer shell structure. It also has good temperature resistance and weather resistance, and can maintain its stable performance in long-term high temperature and harsh environment. In addition, it has flame retardant properties, which protects the safety of electronic devices.

[0021] In one alternative implementation, a shock-absorbing component is also included, disposed between the display structure and the drive plate.

[0022] In this invention, an elastic shock absorber is provided between the rigid drive board and the display structure to prevent the internal display structure from rigidly colliding with the drive board when the display device shakes or is impacted, thereby reducing the risk of collision damage. In addition, the shock absorber can also protect the electrical connection between the drive board and the display structure, improving the reliability of the electrical connection.

[0023] In one alternative implementation, at least two damping elements are symmetrically arranged on the edge of the surface of the display structure facing away from the shielding structure.

[0024] In this invention, multiple shock absorbers are provided to achieve effective buffering between the display structure and the drive board. Attached Figure Description

[0030] like Figure 1As shown, this embodiment provides a display device, including: a housing structure 1, a display structure 2, a shielding structure 3, a protective layer 4, and an elastic member 5. The housing structure 1 includes an accommodating space 11 with an opening 131 on one side; the display structure 2 is disposed within the accommodating space 11; the shielding structure 3 is disposed on the side of the display structure 2 near the opening 131, and the shielding structure 3 has a metal lead-out end connected to the housing structure 1; the protective layer 4 is disposed at least on the side wall of the shielding structure 3 to surround the metal lead-out end of the shielding structure 3; the elastic member 5 is disposed between the protective layer 4 and the housing structure 1, and the elastic member 5 has an elastic force that presses the protective layer 4 when it is offset toward the housing structure 1.

[0031] Specifically, the display structure 2 is housed within the accommodating space 11 of the metal outer shell structure 1. The metal material can be a single metal, an alloy, or other metal composite material. A shielding structure 3 is provided at the opening 131 of the outer shell structure 1 to seal the accommodating space 11. The shielding structure 3 is electrically connected to the outer shell structure 1 through a metal lead-out end, forming external electromagnetic protection for the display structure 2. The shielding structure 3 is a shielding glass, which consists of two pieces of glass of equal thickness and a layer of metal mesh sandwiched in between. The metal mesh serves as the metal lead-out end electrically connected to the outer shell structure 1. In this embodiment, a protective layer 4 is used to wrap the metal lead-out end to prevent damage to it. At the same time, the protective layer 4 acts as an elastic element 5 to press... The direct contact surface between the shielding structure 3 and the display structure 2 is tightened to avoid damage to the metal leads when the elastic element 5 is used to fasten the shielding structure 3 and the display structure 2. The elastic element 5 can be a spring, a spring sheet, or other structures with good elasticity and conductivity. When the display device shakes and causes the display structure 2 and the shielding structure 3 to shift left and right, the elastic element 5 can clamp the above structures to ensure the stability of structures such as the shielding structure 3 and the display structure 2 inside the housing structure 1 within the accommodating space 11. This forms a stable and reliable low-impedance electrical connection path, reducing the risk of electrical connection failure and shielding performance degradation caused by external impacts, and ensuring the electromagnetic protection performance and normal operation of the display device.

[0032] Furthermore, in this embodiment, the display structure 2 and the shielding structure 3 are fitted together, and the projection size of the display structure 2 and the shielding structure 3 on the outer shell structure 1 is the same.

[0033] In this embodiment, the display structure 2, i.e. the display screen, is the same size as the shielding structure 3 and is completely fitted together. The end of the shielding structure 3 away from the display structure 2 is fixed to the outer shell structure 1. The side wall is stably connected to the outer shell structure 1 through the protective layer 4 and the elastic element 5, thereby improving the stability of the display structure 2 in the outer shell structure 1, avoiding the display structure 2 and the shielding structure 3 from shaking under external collisions and causing electrical connection failure, thus ensuring electromagnetic shielding performance.

[0034] In one embodiment, the protective layer 4 covers the sidewalls of the display structure 2 and the shielding structure 3 to ensure protection at the connection between the display structure 2 and the shielding structure 3. An integral and planar contact end is formed between the sidewalls of the shielding structure 3 and the display structure 2, allowing the display structure 2 and the shielding structure 3 to form a single structure within the accommodating space 11, further improving electrical connection stability. Since the end of the elastic member 5 that contacts the outer shell structure 1 is fixedly connected, and the shielding structure 3 and the display structure 2 are embedded from the outside between the elastic member 5, the protective layer 4 completely covers the integral and planar contact surface formed by the sidewalls of the shielding structure 3 and the display structure 2, promoting reliable tightening of the elastic member 5 over the entire sidewall surface of the shielding structure 3 and the display structure 2.

[0035] Preferably, in this embodiment, the protective layer 4 is an embossed tin-plated copper foil. The copper foil has good ductility and good coverage of the metal lead-out end of the shielding structure 3. The tin plating of the copper foil improves the conductivity. The embossing on the surface of the tin-plated copper foil increases the contact friction between the tin-plated copper foil and the metal lead-out end, the shielding structure 3 and the side wall of the display structure 2, and the elastic element 5. In other words, it improves the connection between the above structures, thereby improving the stability of the internal structure of the display device and ensuring electromagnetic protection performance.

[0036] In one embodiment, the housing structure 1 includes a drive plate 12 and a front housing 13 that are fixedly connected, with an opening 131 formed on the front housing 13 and disposed opposite to the drive plate 12.

[0037] The driver board 12 is powered and electrically connected to the display screen to illuminate the display structure 2. The front housing 13 is provided with an edge-locking mechanism for the display structure 2 and the shielding structure 3 on the side opposite to the driver board 12. The opening 131 in the middle area provides a light-emitting path for the display structure 2. The outer shell structure 1 surrounds the display structure 2 and the shielding structure 3, leaving only the opening 131 for the light-emitting path. The internal components of the display device are effectively protected within the outer shell structure 1, ensuring the reliability of the display device.

[0038] Furthermore, the aforementioned outer casing structure 1 also includes a connector 14, which is threadedly connected to the drive plate 12 and the front housing 13 to fix the drive plate 12 and the front housing 13. Threading the drive plate 12 and the front housing 13 provides good stability and facilitates disassembly and assembly.

[0039] In one embodiment, the display device further includes a seal 6, which is disposed at the connection between the shielding structure 3 and the housing structure 1 and is electrically connected to the metal lead-out end of the shielding structure 3 and the housing structure 1; the protective layer 4, the seal 6, the display structure 2 and the housing structure 1 together enclose and seal the accommodating space 11.

[0040] The sealing element 6 seals the part where the shielding structure 3 contacts the outer shell structure 1, improving electrical connection performance and protection of internal components, and ultimately achieving all-round electromagnetic shielding for the display structure 2.

[0041] Preferably, the aforementioned sealing element 6 comprises an integrally molded annular conductive foam. The conductive foam is made of high-quality conductive polyurethane material, and its soft texture helps protect the metal leads and ensures effective contact with the housing structure 1. The conductive foam has good temperature and weather resistance, maintaining stable performance in long-term high-temperature and harsh environments. Furthermore, the conductive foam also has flame-retardant properties, protecting the safety of electronic equipment. In this embodiment, the conductive foam is arranged in an annular shape at the contact position between the shielding structure 3 and the front housing 13 to ensure sealing performance.

[0042] In one embodiment, the display device further includes a shock absorber 7 disposed between the display structure 2 and the drive plate 12.

[0043] An elastic shock absorber 7 is provided between the rigid drive plate 12 and the display structure 2 to prevent the internal display structure 2 from rigidly colliding with the drive plate 12 when the display device shakes or is impacted, thereby reducing the risk of collision damage. In addition, the shock absorber 7 can also protect the electrical connection between the drive plate 12 and the display structure 2, improving the reliability of the electrical connection.

[0044] Preferably, at least two of the aforementioned shock absorbers 7 are symmetrically arranged on the edge of the surface of the display structure 2 facing away from the shielding structure 3. The shock absorbers 7 can be configured as straight strip structures or curved structures, without specific limitations, as long as they can effectively buffer the display structure 2 and the drive plate 12.
