[0030] Reference Figures 1 to 6 The embodiments of this application provide a display device 100 suitable for television.
[0031] The display device 100 includes a housing 10, a display panel 20, a back plate 13, and a conductive element 30.
[0032] The housing 10 protects the internal components of the display device 100 and provides an aesthetic appearance. The housing 10 has an opening through which the display panel 20 is exposed. The shape of the opening is adapted to the shape of the display panel 20. For example, as... Figure 1 and Figure 2 As shown, the opening and display panel 20 are constructed in a rectangular shape.
[0033] The material of the outer shell 10 may include, but is not limited to, ABS plastic (acrylonitrile-butadiene-styrene copolymer), PC plastic (polycarbonate), PS plastic (polystyrene), etc.
[0034] The display panel 20 is disposed within the housing 10 and protrudes from the opening. The display panel 20 and the housing 10 can be connected by means of snap-fit, adhesive, or other methods. The display panel 20 can be a liquid crystal display panel, an organic light-emitting diode display panel, a plasma display panel, etc.
[0035] The back plate 13 is disposed within the housing 10. In some embodiments, the back plate 13 is detachably connected to the housing 10, for example, by snap-fit.
[0036] The backplate 13 provides a mounting base for internal components. For example, internal components such as speakers, power supply boards, signal input ports, and signal output ports can be directly fixed to the backplate 13. Internal components can be fixed to the backplate 13 with screws or clips, which facilitates the installation and positioning of internal components and improves production efficiency.
[0037] The back plate 13 is located inside the display panel 20, where the inside of the display panel 20 refers to the side of the display panel 20 facing the inside of the housing 10. The back plate 13 can be made of steel, aluminum, magnesium alloy, etc.
[0038] The conductive element 30 is a component used to electrically connect the housing 10 and the back plate 13. The conductive element 30 includes a first conductive cloth 32 and a buffer layer 31 stacked together. The first conductive cloth 32 is disposed on the inner side of the housing 10 and is electrically coupled to the back plate 13.
[0039] In some embodiments, using a fiber fabric as a substrate, the fiber fabric is immersed in a chemical plating solution containing metal salts (such as copper sulfate, nickel sulfate, etc.) and a reducing agent. The metal ions are reduced to metal atoms under the action of the reducing agent and deposited on the surface of the fiber fabric, forming a continuous metal plating layer, thereby preparing the first conductive cloth 32. For example, in the manufacturing process of copper-plated conductive cloth, copper ions in the copper sulfate solution form a uniform copper plating layer on the fabric surface under the action of a reducing agent.
[0040] In other embodiments, a first conductive cloth 32 is prepared by placing a fiber fabric as a substrate in a vacuum chamber and depositing metal atoms on the fabric surface through evaporation or sputtering. For example, in the fabrication of copper-plated conductive cloth, copper atoms are evaporated and deposited on the fabric in a vacuum environment to form a conductive copper plating layer.
[0041] The buffer layer 31 is disposed between the first conductive cloth 32 and the display panel 20 and abuts against the display panel 20, which helps to reduce the risk of scratches on the display panel 20 caused by friction between the outer casing 10 and the display panel 20. In addition, the buffer layer 31 insulates the first conductive cloth 32 from the display panel 20.
[0042] In some embodiments, the buffer layer 31 is a buffer foam.
[0043] In the display device 100, the outer casing 10 and the buffer layer 31 are typically insulating components, while the back panel 13 is a metal component. The outer casing 10 is non-conductive, and the charge on the outer casing 10 cannot flow freely, leading to the accumulation of static electricity. In the event of air breakdown, the static electricity in the outer casing 10 can be conducted to the display panel 20 through the air, easily causing malfunctions in the display panel 20.
[0044] In this embodiment, utilizing the conductor property of the back plate 13, the first conductive cloth 32 is disposed on the inner side of the outer shell 10 and electrically coupled to the back plate 13, so that the first conductive cloth 32 provides a charge transfer channel. The charge on the outer shell 10 can be conducted to the back plate 13 through the first conductive cloth 32, and then the charge is electrically neutralized through the back plate 13 and released into the surrounding environment. Thus, static electricity is transmitted to the back plate 13 through the first conductive cloth 32 and then released through the back plate 13, which helps to improve the abnormal problems of the display panel 20 caused by static electricity conduction to the display panel 20.
[0045] Furthermore, the conductive fabric possesses excellent flexibility, allowing it to be bent and folded to adapt to complex shapes and structures. In this embodiment, by using the first conductive fabric 32 as the conductive layer in the conductive component 30, the first conductive fabric 32 can closely adhere to the outer shell 10, resulting in good contact stability between the outer shell 10 and the first conductive fabric 32. Moreover, the first conductive fabric 32 is thin and occupies less space, helping to reduce the volume of the conductive component 30 and minimize space usage.
[0046] In addition, in this embodiment of the application, by stacking the first conductive cloth 32 and the buffer layer 31, the conductive component 30 can be used as a prefabricated component and directly assembled onto the display device 100. That is, the installation of the buffer layer 31 and the first conductive cloth 32 onto the display device 100 can be completed in one go, without having to install the first conductive cloth 32 and the buffer layer 31 onto the display device 100 one by one. The assembly of the prefabricated component and the installation of the prefabricated component onto the display device 100 can be carried out simultaneously, which can improve assembly efficiency.
[0047] Reference Figure 1 , Figure 2 and Figure 5 In some embodiments, the housing 10 includes a middle frame 12 and a front frame 11, the front frame 11 being sleeved on the middle frame 12, the back plate 13 and the display panel 20 being disposed on the middle frame 12, the front frame 11 having an opening, the front frame 11 being disposed on the front side of the display panel 20, and the first conductive cloth 32 being disposed on the inner side of the front frame 11.
[0048] Since the front frame 11 is close to the display panel 20, in this embodiment, the first conductive cloth 32 is disposed on the inner side of the front frame 11 so that the buffer layer 31, which is stacked with the first conductive cloth 32, can abut against the display panel 20.
[0049] In some embodiments, the housing 10 further includes a rear cover 14 located on the side of the back panel 13 away from the display panel 20, and the middle frame 12 is also sleeved on the rear cover 14.
[0050] Reference Figure 5 In some embodiments, a limiting groove 111 is provided on the inner side of the front frame 11, and a portion of the conductive component 30 is embedded in the limiting groove 111. By embedding the conductive component 30 in the limiting groove 111, the movement of the conductive component 30 is restricted by the limiting groove 111, making it less likely for the conductive component 30 to loosen during the use of the display device 100. This helps to improve the problem of electrostatic discharge failure caused by the loosening of the conductive component 30.
[0051] Reference Figure 5 and Figure 6 In some embodiments, the conductive element 30 further includes a second conductive cloth 33. The second conductive cloth 33 may be constructed in a rectangular shape.
[0052] One end of the second conductive cloth 33 is connected to the first conductive cloth 32, and the other end is connected to the back plate 13. The area of the second conductive cloth 33 is smaller than the area of the first conductive cloth 32, and the first conductive cloth 32 is electrically coupled to the back plate 13 through the second conductive cloth 33.
[0053] Compared to the first conductive cloth 32, the second conductive cloth 33 has a smaller area and occupies less space. In this embodiment, by setting the second conductive cloth 33 as the connection structure between the first conductive cloth 32 and the back plate 13, the second conductive cloth 33 can be bent and connected to the back plate 13 in a smaller space, which helps to reduce the difficulty of connecting the conductive component 30 to the back plate 13.
[0054] One or more second conductive fabrics 33 can be provided. (Refer to...) Figure 6 In some embodiments, two second conductive cloths 33 are provided, and the two second conductive cloths 33 are spaced apart along the length direction of the conductive member 30.
[0055] By setting multiple second conductive cloths 33, if one of the multiple second conductive cloths 33 fails, the other conductive cloths can still electrically couple the first conductive cloth 32 to the back plate 13, which helps to reduce the risk of failure of the first conductive cloth 32 to the back plate 13.
[0056] In some embodiments, the material of the second conductive cloth 33 is the same as that of the first conductive cloth 32, so as to facilitate the fabrication of the conductive element 30.
[0057] In some embodiments, the first conductive cloth 32 and the second conductive cloth 33 are integrally formed, which eliminates the connection step between the first conductive cloth and the second conductive cloth 33 and helps to improve the production efficiency of the conductive component 30.
[0058] To facilitate the connection between the second conductive cloth 33 and the back plate 13, in some embodiments, the second conductive cloth 33 is bonded to the back plate 13.
[0059] In some embodiments, the area of the second conductive cloth 33 is 350 mm². 2 Up to 450mm 2 between.
[0060] The area of the second conductive cloth 33 is greater than 350 mm². 2 The area of the second conductive cloth 33 is not too small, so as to provide a sufficient conduction path for static electricity; the area of the second conductive cloth 33 is less than 450 mm². 2 The area of the second conductive cloth 33 is not too large, which helps to control material costs. Therefore, the area of the second conductive cloth 33 is 350 mm². 2 Up to 450mm 2 It can balance the effect of static electricity release and the cost of materials.
[0061] For example, the area of the second conductive cloth 33 can be 350 mm². 2 360mm 2 370mm 2 380mm 2 390mm 2 400mm 2 410mm 2 420mm 2 430mm 2 450mm 2 And any values in between.
[0062] In some embodiments, the thickness of the conductive element 30 is between 1.4 mm and 1.5 mm. Controlling the thickness of the conductive element 30 within this range helps to balance the volume and structural stability of the conductive element 30.
[0063] For example, the thickness of the conductive element 30 can be 1.4mm, 1.41mm, 1.42mm, 1.43mm, 1.44mm, 1.45mm, 1.46mm, 1.47mm, 1.48mm, 1.49mm, 1.5mm, or any value between these values.
[0064] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
