[0048] In display devices, the Source board is used to process the video source signal and transmit it to the display screen for image display. During the assembly process of the various parts of the display device, in order to reduce the volume after assembly and ensure the reliability of the display device after assembly, the Source board generally needs to be fixed on the back of the display screen, and the Source board also needs to be grounded to conduct static electricity.

[0049] In the prior art, there are three common ways to fix the Source board. The first is to pre-fix the Source board with tape, and then fix the Source board and the display screen with foam. The second is to fix the Source board with a plastic structural member. The Source board does not need to be pre-fixed with tape, and can be directly inserted into the plastic structural member. The third is to fix the Source board with a silicone structural member. After the Source board is fixed, the Source board is connected to the ground wire or other conductive components through conductive cloth to achieve static electricity conduction.

[0050] However, in the first Source board fixing method, during the Source board fixing and assembling process, the Source board needs to be pre-fixed with tape to prevent damage caused by shaking of the Source board. After the display screen is flipped over, the Source board is positioned and fixed by pasting. Moreover, when the Source board needs to be repaired, the foam needs to be replaced, the residual foam needs to be cleaned, and then reattached. Therefore, the first Source board fixing method has the problem of complicated steps and complicated repair.

[0051] In the second Source board fixing method, the size of the Source board is not fixed, but varies according to the specific display device and design requirements. However, the plastic structural parts can only fit Source boards of certain sizes, and the Source boards that cannot be fit need to be re-prepared with the corresponding plastic structural parts. Therefore, the plastic structural parts used to fix the Source board have the problem of poor versatility.

[0052] In the third Source board fixing method, the Source board is easy to fall off due to the poor hardness of the fixing silicone, and the silicone structure can only fit Source boards of certain sizes, and the Source boards that cannot be fit need to be re-prepared with the corresponding silicone structure. Therefore, the silicone structure used to fix the Source board has the problem of poor versatility.

[0053] Moreover, in the above three solutions, the structural parts used to fix the Source board are all made of insulating materials. Considering that the Source board needs to be grounded with conductive cloth, the above three solutions also require additional personnel to attach conductive cloth. The larger the panel size, the more conductive cloth is required. For example, 32-43 inches require 2-4 conductive cloths, and 85 inches require 8 conductive cloths. Production needs to arrange personnel to attach.

[0054] In summary, the current fixing method of the Source board has the problems of poor versatility and low fixing efficiency.

[0055] In view of this, an embodiment of the present application provides a display device. The display device includes a back plate, a display screen, a Source plate and a conductive fixing component. The display screen is arranged on one side of the back plate. The Source plate is arranged between the back plate and the display screen. The Source plate and the display screen are electrically connected. The conductive fixing component is arranged between the back plate and the display screen. By arranging the conductive fixing component between the back plate and the display screen, the conductive fixing component not only plays a role in fixing the Source plate, but also electrically connects the Source plate and the back plate to conduct static electricity of the Source plate, which can effectively prevent static electricity from damaging the electronic components on the Source plate. In this way, the display device provided by the present application does not need to perform an additional process of pasting conductive cloth on the Source plate, which reduces the production steps of the display device and improves the production efficiency of the display device. The conductive fixing component includes a mounting plate, a fixing component and a connecting plate. The mounting plate is connected to the fixing component through the connecting plate. The mounting plate is connected to the back plate. The fixing component includes a fixing area. The Source plate is located in the fixing area. The Source plate is electrically connected to the back plate through the conductive fixing component. By arranging the Source plate in the fixing area, the fixing area limits the movement of the Source plate and improves the connection stability of the Source plate. At the same time, the fixing area of ​​the fixing component in the display device provided by the present application can adapt to Source boards of different sizes, thereby improving the versatility of the conductive fixing component.

[0056] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0057] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0058] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0059] The display device provided in the embodiments of the present application may have various implementation forms, for example, it may be a television, a smart television, a laser projection device, a monitor, an electronic bulletin board, an electronic table, etc.

[0060] Figure 1 A schematic diagram schematically shows the structure of a display device at a first viewing angle provided in an embodiment of the present application. Figure 2 A schematic diagram schematically shows the structure of a second viewing angle of a display device provided in an embodiment of the present application. Figure 3 A schematic diagram schematically shows the structure of a display device at a third viewing angle provided in an embodiment of the present application. Figure 4 The schematic diagram schematically shows the structure of the conductive fixing component 400 of the display device provided in the embodiment of the present application at a first viewing angle. Figure 5 A schematic diagram schematically shows the structure of a conductive fixing component 400 of a display device provided in an embodiment of the present application at a second viewing angle. Figure 6 A schematic diagram schematically shows the structure of a conductive fixing component 400 of a display device provided in an embodiment of the present application from a third viewing angle.

[0061] The present application provides a display device. Figures 1 to 6 As shown, the display device includes a back plate 100, a display screen 200, a Source plate 300 and a conductive fixing component 400. The display screen 200 is arranged on one side of the back plate 100. The back plate 100 is used to support and fix the display screen 200 to keep it flat and stable. The back plate 100 provides a sturdy structure to prevent the display screen 200 from bending or deforming during use. The Source plate 300 is arranged between the back plate 100 and the display screen 200. The Source plate 300 is electrically connected to the display screen 200. The Source plate 300 is mainly responsible for driving and controlling the pixels of the display screen 200. By setting the conductive fixing component 400 between the back plate 100 and the display screen 200, the conductive fixing component 400 not only fixes the Source plate 300, but also electrically connects the Source plate 300 and the back plate 100 to conduct static electricity from the Source plate 300, which can effectively prevent static electricity from causing damage to the Source plate 300. In this way, the display device provided by the present application does not need to perform an additional process of pasting conductive cloth on the Source plate 300, which reduces the production steps of the display device and improves the production efficiency of the display device. The conductive fixing component 400 is set between the back plate 100 and the display screen 200. The conductive fixing component 400 includes a mounting plate 410, a fixing component 420 and a connecting plate 430. The mounting plate 410 is connected to the fixing component 420 through the connecting plate 430.

[0062] The mounting plate 410 is connected to the back plate 100. The fixing component 420 includes a fixing area. The Source plate 300 is located in the fixing area. The Source plate 300 is electrically connected to the back plate 100 through the conductive fixing component 400. By arranging the Source plate 300 in the fixing area, the fixing area limits the movement of the Source plate 300, thereby improving the connection stability of the Source plate 300 in the display device. At the same time, the fixing area of ​​the fixing component 420 in the display device provided in the present application can adapt to Source plates 300 of different sizes, thereby improving the versatility of the conductive fixing component 400.

[0063] Figure 7 The structural diagram of the mounting plate 410 of the display device provided in the embodiment of the present application is schematically shown.

[0064] In some possible implementations, reference Figure 7 As shown, the mounting plate 410 includes a first surface 412 and a second surface 411. The first surface 412 is connected to the back plate 100. The second surface 411 is connected to the fixing component 420 via the connecting plate 430. By connecting the first surface 412 to the back plate 100, the connection strength between the mounting plate 410 and the back plate 100 is improved, so that the mounting plate 410 remains flat and stable, ensuring that the conductive fixing component 400 provides stable support for the Source plate 300. The second surface 411 is connected to the fixing component 420 via the connecting plate 430, ensuring that the Source plate 300 is stable in the fixing area.

[0065] In some achievable ways, the display device further includes an elastic connector. The elastic connector connects the mounting plate 410 and the back plate 100. The elastic connector includes a double-sided foam tape. The double-sided foam tape can provide a stable mechanical connection between the mounting plate 410 and the back plate 100 by connecting the mounting plate 410 and the back plate 100 with the double-sided foam tape. Moreover, the process of connecting the mounting plate 410 and the back plate 100 with the double-sided foam tape is simple and easy to operate, which simplifies the installation process and improves the installation efficiency of the conductive fixing component 400. At the same time, the double-sided foam tape has a certain flexibility and can adapt to the slight deformation between the mounting plate 410 and the back plate 100 to ensure the stability of the connection. In addition, the double-sided foam tape can absorb the vibration and impact generated by the display device during transportation and use, and protect the internal components. During the operation of the display device, relative displacement may occur between the components due to thermal expansion or mechanical stress. The double-sided foam tape can relieve these stresses and prevent component damage.

[0066] The mounting plate 410 extends along a first direction. The first direction is parallel to the extending direction of the back plate 100. The first direction refers to the direction indicated by X in 1. Along the first direction, a mounting protrusion 412a is provided on the first surface 412. The mounting protrusion 412a abuts against the back plate 100.

[0067] Exemplarily, during the use of the display device, the Source board 300 may accumulate static electricity due to various reasons (such as friction, electric field, etc.). If the accumulated static electricity is not discharged in time, it may cause damage to the Source board 300 or failure of the display device. In the present application, by setting a mounting protrusion 412a on the mounting plate 410, the mounting protrusion 412a connects the mounting plate 410 and the back plate 100, and the mounting plate 410 is connected to the Source board 300 through the connecting plate 430 and the fixing component 420, the static electricity generated by the Source board 300 can be sequentially transmitted through the fixing component 420, the connecting plate 430, and the mounting plate 410, and finally transmitted to the back plate 100 through the mounting protrusion 412a, so as to realize the discharge of the static electricity of the Source board 300. The discharge of static electricity can effectively prevent static electricity from damaging the electronic components on the Source board 300, extend the service life of the Source board 300 and the display device, improve the reliability and stability of the display device, and reduce the influence of electromagnetic interference caused by static electricity accumulation on the performance of the display device.

[0068] Exemplarily, there may be multiple mounting protrusions 412 a, and the present application does not limit the number of mounting protrusions 412 a.

[0069] Figure 8 A schematic diagram schematically shows the structure of a first viewing angle of a fixing component 420 of a display device provided in an embodiment of the present application. Fig. 9 A schematic diagram schematically shows the structure of the second viewing angle of the fixing component 420 of the display device provided in an embodiment of the present application. Fig.10 The structural diagram of the first fixing plate 421 of the display device provided in the embodiment of the present application is schematically shown.

[0070] In some possible implementations, reference Figures 8 to 10 As shown, the fixing member 420 includes a first fixing plate 421 , a second fixing plate 422 and a bottom fixing plate 423 . A first end of the first fixing plate 421 and a first end of the second fixing plate 422 are connected via the bottom fixing plate 423 .

[0071] The first fixing plate 421 and the second fixing plate 422 both extend along the first direction.

[0072] Along the direction from the display screen 200 to the back plate 100, the first fixing plate 421 and the second fixing plate 422 are arranged opposite to each other and surround a fixing area. The source plate 300 is located in the fixing area.

[0073] Exemplarily, by combining the first fixing plate 421, the second fixing plate 422 and the bottom fixing plate 423 to form a stable fixing area, and placing the Source plate 300 in the fixing area, the fixing area provides good mechanical support and stability for the Source plate 300, preventing the Source plate 300 from being displaced or loosened during use. At the same time, this structure simplifies the installation process of the Source plate 300 and improves the installation efficiency of the Source plate 300.

[0074] In addition, since the fixing area can adapt to Source boards 300 of different sizes, the types and quantities of the conductive fixing components 400 can be reduced, reducing the specific design requirements for Source boards 300 of different sizes. In addition, the design of fixing areas that adapt to different sizes reduces the need for different molds and tooling, thereby reducing production costs.

[0075] In some achievable embodiments, the first fixing plate 421 is located on a side of the second fixing plate 422 away from the mounting plate 410. The first fixing plate 421 includes a first fixing surface 421b. The second fixing plate 422 includes a second fixing surface 422b. The first fixing surface 421b and the second fixing surface 422b surround a fixing area.

[0076] For example, refer to Figures 1 to 10 As shown, along the direction from the display screen 200 to the back plate 100, the first fixing plate 421, the second fixing plate 422, the connecting plate 430 and the mounting plate 410 are sequentially arranged. Figure 1 The first fixing plate 421 and the second fixing plate 422 are arranged relative to each other, and the first fixing surface 421b and the second fixing surface 422b are surrounded by a fixing area for accommodating and fixing the Source board 300. This design not only provides stable mechanical support and reliable electrical connection, but also can adapt to Source boards 300 of different sizes, improve the versatility of the conductive fixing assembly 400, and reduce production costs. Through reasonable design and standardized production, the fixing component 420 can significantly improve the overall performance and reliability of the display device and extend the service life of the display device.

[0077] In some practicable embodiments, a first protrusion 421 a is disposed on a portion of the first fixing surface 421 b close to the bottom fixing plate 423 . The first protrusion 421 a abuts against the Source plate 300 .

[0078] A second protrusion 422a is disposed on a portion of the second fixing surface 422b away from the bottom fixing plate 423. The second protrusion 422a abuts against the Source plate 300.

[0079] By arranging the first protrusion 421a and the second protrusion 422a on the first fixing surface 421b and the second fixing surface 422b, the first protrusion 421a and the second protrusion 422a are both in contact with the Source board 300, thereby further enhancing the fixing effect of the Source board 300. This design not only provides stable mechanical support and reliable electrical connection, but also can adapt to Source boards 300 of different sizes, thereby improving the versatility of the conductive fixing assembly 400 and reducing production costs.

[0080] For example, refer to Figure 8 As shown, the first protrusion 421a is arranged at a position of the first fixing surface 421b close to the bottom fixing plate 423. The second protrusion 422a is arranged at a position of the second fixing surface 422b away from the bottom fixing plate 423. The Source board 300 is located in the fixing area, fixed and protected by the first fixing surface 421b and the second fixing surface 422b, and at the same time, the first protrusion 421a and the second protrusion 422a are respectively abutted against different parts of the Source board 300, further enhancing the fixing effect of the conductive fixing component 420 on the Source board 300, and preventing displacement or loosening during use.

[0081] For example, there may be a plurality of first protrusions 421 a, and the present application does not limit the number of first protrusions 421 a. There may be a plurality of second protrusions 422 a, and the present application does not limit the number of second protrusions 422 a.

[0082] In some achievable embodiments, the Source board 300 includes an electrical connection area. The second protrusion 422a is electrically connected to the electrical connection area. The electrical connection area of ​​the Source board 300 may be a copper leakage area, which may serve as an electrostatic discharge path to conduct static electricity from the Source board 300, thereby preventing static electricity accumulation from damaging the Source board 300. The second protrusion 422a contacts the copper leakage area of ​​the Source board 300, so that static electricity is introduced into the backplane 100.

[0083] In some achievable embodiments, the fixing component 420 further includes a guide plate 440. The first end of the guide plate 440 is connected to the end of the first fixing plate 421 away from the bottom fixing plate 423. The second end of the guide plate 440 extends toward the display screen 200. The guide plate 440 can provide a guiding function during the installation of the Source plate 300, guide the Source plate 300 to be placed in the fixing area, improve the installation efficiency of the Source plate 300, and reduce installation errors. In addition, the guide plate 440 can also provide additional support to ensure that the Source plate 300 does not shift or tilt during the installation process, thereby improving the installation accuracy.

[0084] In some achievable embodiments, the mounting plate 410, the connecting plate 430 and the fixing component 420 are an integrally formed part. The integrally formed part is a metal part. The integrally formed design reduces the number of connection points between the conductive fixing components 400, reduces the mechanical stress concentration and potential failure points at the connection points of each part, and improves the reliability of the overall structure of the conductive fixing component 400. At the same time, the integrally formed design simplifies the manufacturing process of the conductive fixing component 400, reduces the assembly steps and time, and improves production efficiency and consistency. By designing the mounting plate 410, the connecting plate 430 and the fixing component 420 as an integrally formed part and selecting metal materials, the mechanical strength and corrosion resistance of the components can be significantly improved, and the service life of the conductive fixing component 400 can be increased.

[0085] For example, the metal piece has high strength and rigidity, can withstand large mechanical stress and load, and ensure the stability and reliability of the conductive fixing assembly 400. The metal piece has good durability and fatigue resistance, and can maintain stable performance during long-term use.

[0086] Exemplarily, the material of the metal part includes but is not limited to aluminum, steel, and stainless steel.

[0087] In some possible implementations, reference Figure 1 As shown, the display device further includes a COF 500. The source board 300 extends along a second direction. The second direction intersects the first direction. The second direction refers to Figure 1 The direction shown in Y.

[0088] The opposite ends of the source board 300 extending along the second direction are electrically connected to the display screen 200 through the chip-on-film 500. The chip-on-film 500 transmits the signal of the source board 300 to the display screen 200, ensuring that the display screen 200 can receive and display the correct image. The chip-on-film 500 has a certain flexibility, can adapt to the shape and installation requirements of the display device, and provide a reliable mechanical connection. The chip-on-film 500 can absorb a certain amount of mechanical stress and vibration to protect the stability of the electrical connection.

[0089] The embodiment of the present application provides a display device, including a back plate 100, a display screen 200, a source plate 300 and a conductive fixing assembly 400. The display screen 200 is used to be arranged on one side of the back plate 100. The source plate 300 is used to be arranged between the back plate 100 and the display screen 200. The source plate 300 is used to be electrically connected to the display screen 200.

[0090] The conductive fixing assembly 400 is disposed between the back plate 100 and the display screen 200. The conductive fixing assembly 400 includes a mounting plate 410, a fixing component 420 and a connecting plate 430. The mounting plate 410 is used to connect with the fixing component 420 through the connecting plate 430.

[0091] The mounting plate 410 is used to connect with the back plate 100. The fixing component 420 includes a fixing area. The Source plate 300 is located in the fixing area. The Source plate 300 is used to be electrically connected to the back plate 100 through the conductive fixing component 400. By arranging the conductive fixing component 400 between the back plate 100 and the display screen 200, the conductive fixing component 400 not only plays the role of fixing the Source plate 300, but also electrically connects the Source plate 300 and the back plate 100 to conduct the static electricity of the Source plate 300, which can effectively prevent static electricity from causing damage to the Source plate 300. In this way, the display device provided by the present application does not need to perform an additional conductive cloth pasting process on the Source plate 300, which reduces the production steps of the display device and improves the production efficiency of the display device. By arranging the Source plate 300 in the fixing area, the fixing area limits the movement of the Source plate 300, and improves the connection stability of the Source plate 300 in the display device. At the same time, the fixing area of ​​the fixing component 420 in the display device provided by the present application can adapt to Source plates 300 of different sizes, which improves the versatility of the conductive fixing component 400.
