Description

Technical Field

[0001] The present invention belongs to the technical field of display screens, and more specifically, it is a display screen based on graphene heat dissipation and a manufacturing method thereof. Background Art

[0002] With the continuous development of display technology, LED display screens have been widely used in many fields such as advertising, monitoring, and entertainment due to their advantages of high brightness, high contrast, and long lifespan. However, with the continuous improvement of the resolution and brightness of LED display screens, the heat generated during their operation is also increasing continuously, which poses higher requirements for the heat dissipation performance of the display screens.

[0003] Traditional heat dissipation methods, such as solely relying on fans for heat dissipation, although can alleviate the problem of heat accumulation within a certain range, their inherent limitations are becoming increasingly obvious. Specifically, fan heat dissipation has the problem of low heat dissipation efficiency and is difficult to effectively cope with the heat output under high-load operating conditions. At the same time, the noise generated by the rotation of the fan not only affects the user experience but may also cause interference to the surrounding environment. In addition, the continuous power consumption also leads to high energy consumption, which is not conducive to energy conservation, emission reduction, and sustainable development.

[0004] Therefore, those skilled in the art have proposed a display screen based on graphene heat dissipation and a manufacturing method thereof to solve the problems raised in the background art. Summary of the Invention

[0019] A manufacturing method of a display screen based on graphene heat dissipation includes the following steps:

[0020] S1. Preparation of the LED display screen substrate: First, select an LED display screen substrate with a flat surface, no scratches, no dust and other impurities. Then, use a dust-free cloth and a solvent to clean the surface of the substrate to remove pollutants such as grease and dust.

Through the excellent thermal conductivity of the graphene heat dissipation plate, the heat generated inside the LED display screen can be quickly exported and dissipated into the surrounding environment, and this process does not consume additional electricity or other forms of energy. Therefore, the LED display screen using the graphene heat dissipation plate can manage its energy consumption more effectively during operation, thereby reducing the electricity bill and lowering the overall operating cost.

[0027] 2. The present invention monitors the temperature inside the LED display screen in real time through a temperature sensor.

[0036] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0037] As shown in the attached Figure 1 to the attached Figure 6 as shown:

[0038] Embodiment 1: The present invention provides a display screen based on graphene heat dissipation, including:

[0039] A housing 1, with a screen 2 provided at the front end of the housing 1 and a substrate 3 provided at the rear end of the housing 1;

[0040] A graphene heat dissipation plate 4, which is installed at the rear end of the substrate 3. A heat dissipation fin 5 is provided at the rear end of the graphene heat dissipation plate 4, and a heat pipe 6 is provided inside the heat dissipation fin 5; The graphene heat dissipation plate 4 is made of a graphene film or a graphene composite material and has extremely high thermal conductivity.

[0041] A temperature sensor 7, which is installed on one side of the housing 1, and the sensing end of the temperature sensor 7 extends into the interior of the housing 1;

[0042] A wind power component 8, which is installed at the rear end of the housing 1 and is used to provide wind power.

[0043] The wind power component 8 includes a housing 81 provided at the rear end of the housing 1, and a plurality of heat dissipation holes 82 are provided on the outer surface of the housing 81.

[0044] An installation shell 83 penetrates through the rear end of the housing 81. A fixing frame 84 is provided inside the installation shell 83. A rotating shaft 86 is rotatably installed inside the fixing frame 84, and a plurality of blades 87 are evenly installed on the outer surface of the rotating shaft 86.

[0045] A driving component 85 is installed on one side of the installation shell 83, and the output end of the driving component 85 is connected to the rotating shaft 86. The driving component 85 includes, but is not limited to, a variable speed motor.

[0046] As can be seen from the above, a graphene heat dissipation plate 4 is installed on the substrate 3 of the LED display screen. When the LED display screen operates and generates heat, this graphene heat dissipation plate 4 will quickly absorb and disperse the heat generated by the chips inside the display screen. Then, the heat is effectively discharged through the heat dissipation holes 82 on the housing 81, and the heat dissipation fins 5 and the heat pipes 6 provided can further improve the heat dissipation effect.

[0047] To monitor the internal temperature of the LED display in real time, a temperature sensor 7 is equipped inside the LED display. Once the temperature reaches the preset threshold, the PLC controller will activate the driving member 85 to drive the rotation of the rotating shaft 86, thereby driving the blades 87 to rotate rapidly. This process forms a negative pressure inside the housing 81, attracting external air to enter and accelerating the heat dissipation efficiency of the graphene heat dissipation plate 4, the heat dissipation fins 5, and the heat pipe 6.

[0048] When the temperature sensor 7 detects that the internal temperature of the LED display has dropped below the threshold, the PLC controller will instruct the driving member 85 to stop working, thus ending this enhanced heat dissipation process.

[0049] The graphene heat dissipation plate 4 has high thermal conductivity and a high heat radiation coefficient due to its unique structure. It can quickly conduct the heat generated by the internal chips of the LED display and discharge it through the heat dissipation holes 82, effectively reducing the operating temperature of the display. The heat dissipation fins 5 and the heat pipe 6 enable the heat to be transferred to the external environment more quickly, thereby improving the heat dissipation efficiency of the entire system. Through the excellent thermal conductivity of the graphene heat dissipation plate 4, the graphene heat dissipation plate 4 can quickly conduct and dissipate the heat generated inside the LED display into the surrounding environment. This process does not require additional power consumption or other forms of energy. Therefore, the LED display using the graphene heat dissipation plate 4 can manage its energy consumption more effectively during operation, thereby reducing electricity bills and lowering the overall operating cost.

[0050] Secondly, the temperature inside the LED display is monitored in real time through the temperature sensor 7. When the temperature reaches the preset threshold, the PLC controller will automatically activate the driving member 85 to drive the blades 87 to rotate, accelerating the heat dissipation speed. When the temperature drops below the threshold, the PLC controller will stop the driving member 85 from working, thus achieving precise temperature control. This not only ensures the stable operation of the display but also effectively avoids unnecessary energy consumption through an intelligent temperature control mechanism, realizing the efficient utilization of energy.

[0051] Embodiment 2: This is the second embodiment of the present invention, including a protection member 9 and a wind power member 8. The protection member 9 is installed inside the wind power member 8 and is used to protect the display screen.

[0052] The wind power member 8 includes a housing 81 provided at the rear end of the casing 1, and a plurality of heat dissipation holes 82 are provided on the outer surface of the housing 81.

[0053] The protection member 9 includes a dust-proof net 91 provided inside the housing 81.

[0054] A threaded rod 92 is rotatably installed inside the housing 81, a lifting plate 94 is slidably installed inside the housing 81, a threaded ring is provided inside the lifting plate 94, and the threaded rod 92 meshes with the threaded ring.

[0055] A control member 93 is provided at the upper end of the outer shell 81. The output end of the control member 93 is connected to a threaded rod 92. A cleaning brush 95 is provided on one side of the lifting plate 94. The cleaning brush 95 contacts the dust-proof net 91. The control member 93 includes, but is not limited to, an electric motor.

[0056] A bottom box 96 is inserted into the lower end of the outer shell 81. Both ends of the bottom box 96 are installed on both sides of the outer shell 81 through fixing bolts 97.

[0057] As can be seen from the above, in order to ensure the internal cleanliness and operation safety of the LED display screen, a dust-proof net 91 is added at the front end of the heat dissipation fins 5. The dust-proof net 91 can not only effectively block the dust entering the interior of the outer shell 81 through the heat dissipation holes 82, but also prevent the dust carried by the wind member 8 when inhaling the outside air from entering the interior of the display screen, thereby avoiding the possible damage to the LED display screen caused by dust.

[0058] When it is necessary to clean the dust-proof net 91, the PLC controller will start the control member 93 to rotate it forward or backward, thereby driving the rotation of the threaded rod 92. At this time, the threaded ring inside the lifting plate 94 meshes tightly with the threaded rod 92, driving the lifting plate 94 to move up and down reciprocally. This movement drives the cleaning brush 95 to move on one side of the dust-proof net 91, effectively removing the dust attached to the dust-proof net 91.

[0059] The dust cleaned off will fall into the bottom box 96 below for collection. In order to facilitate the cleaning of the dust in the bottom box 96, the fixing bolts 97 are detachable. By removing the fixing bolts 97, the bottom box 96 can be pulled out for thorough cleaning. This design not only improves the cleaning efficiency but also ensures the continuous and stable operation of the LED display screen.

[0060] By adding a dust-proof net 91 at the front end of the heat dissipation fins 5, the dust entering the interior of the outer shell 81 through the heat dissipation holes 82 and the dust carried by the wind member 8 when inhaling the outside air are effectively blocked, significantly reducing the risk of dust damaging the internal components of the LED display screen. Secondly, through the tight meshing of the threaded rod 92 with the threaded ring inside the lifting plate 94, the reciprocating up and down movement of the lifting plate 94 is realized, and then the cleaning brush 95 is driven to move on one side of the dust-proof net 91, effectively removing the dust attached to the dust-proof net 91. The dust cleaned off will fall into the bottom box 96 below for collection, avoiding secondary pollution caused by dust scattering and also facilitating subsequent cleaning work. Through the effective dust-proof and cleaning mechanism of the protection member 9, the erosion of dust on the internal components of the LED display screen can be reduced, thereby extending the service life of the display screen, helping to maintain the performance stability of the LED display screen, and reducing failures and performance degradation caused by dust.

[0063] S2. Pretreatment of the graphene heat dissipation plate 4: Then, use a cleaning agent to clean the graphene heat dissipation plate 4 to remove impurities such as grease and dust on the surface. After that, place the cleaned graphene heat dissipation plate 4 in a drying device for drying treatment.

[0064] S3. Mounting: Then, use a gluing device to evenly coat an adhesive on the back of the LED display screen substrate 3 or the surface of the graphene heat dissipation plate 4. Then, adopt a process method to closely attach the graphene heat dissipation plate 4 to the back of the LED display screen substrate 3.

[0065] S4. Installation of auxiliary components: Then, use an adhesive to install the auxiliary heat dissipation elements, namely heat dissipation fins 5 and heat pipes 6, on the graphene heat dissipation plate 4.
