Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a display screen with electrostatic shielding function. Background Technology

[0002] With the rapid development of electronic technology, displays are increasingly widely used in various fields, from consumer electronics to industrial control, medical equipment, and aerospace. However, the presence of static electricity seriously affects the normal operation and lifespan of displays. Static electricity can interfere with the display effect, causing problems such as image flickering, discoloration, and blurring. It can even damage the electronic components inside the display, causing permanent damage and bringing economic losses and inconvenience to users. Therefore, displays with electrostatic shielding function have become an urgent technological direction for the industry.

[0003] In the prior art, some displays use complex electrostatic discharge (ESD) protection chips in their internal circuitry to neutralize accumulated ESD charges through the chip's ESD discharge channels. Others optimize the display's wiring layout to reduce the exposure of ESD-sensitive areas and enhance the insulation performance of the circuit board to reduce ESD generation and accumulation. In addition, some displays use special insulating coating materials to cover the surface of key components of the display, preventing direct contact between ESD and components through physical isolation.

[0004] However, most of these existing technologies focus on protection at the internal circuit and material level. When facing a strong external electrostatic field environment, they are difficult to provide effective shielding protection for the display screen as a whole. The external electrostatic field can still penetrate the display screen shell and interfere with the internal circuit, causing display abnormalities. They cannot meet the requirements for stable operation of the display screen in strong electromagnetic interference and high electrostatic environment. Therefore, a display screen with electrostatic shielding function is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a display screen with electrostatic shielding function, which aims to improve the problem in the prior art where the display screen lacks overall effective shielding protection in the external strong electrostatic field environment, causing the external electrostatic field to penetrate the shell and interfere with the internal circuit, resulting in display abnormalities.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A display screen with electrostatic shielding function includes a display screen, wherein the display screen has an interface inside, and a shielding component is provided on one side of the display screen;

[0008] The shielding assembly includes a shielding cover, which is slidably connected to one side of the display screen. A graphite thermal conductive patch is fixedly connected to one side of the shielding cover. Both the shielding cover and the graphite thermal conductive patch have heat dissipation grooves inside. A plurality of rubber sheets are fixedly connected to one side of the graphite thermal conductive patch, and one side of the rubber sheets is in contact with one side of the display screen. An antistatic coating is provided on one side of the graphite thermal conductive patch. An installation assembly is provided inside the shielding cover.

[0009] As a further description of the above technical solution:

[0010] The mounting assembly includes a fixing block and a connecting shaft. One side of the fixing block is fixedly connected to one side of the display screen, and the outer wall of the connecting shaft is fixedly connected to the inside of the shielding cover.

[0011] As a further description of the above technical solution:

[0012] The fixing block has a slot inside, and a spring is installed inside the slot.

[0013] As a further description of the above technical solution:

[0014] One end of the spring is fixedly connected to the inner wall of the fixed block, and the other end is fixedly connected to a limit ring.

[0015] As a further description of the above technical solution:

[0016] A transmission column is slidably connected inside the connecting shaft, and a rotating shaft is fixedly connected to one end of the transmission column.

[0017] As a further description of the above technical solution:

[0018] A knob is fixedly connected to one end of the rotating shaft, and a locking pin is fixedly connected inside the transmission column.

[0019] As a further description of the above technical solution:

[0020] The engaging post engages with the slot, and a spring is provided on the outer wall of the transmission post.

[0021] As a further description of the above technical solution:

[0022] One end of the spring is fixedly connected to one side of the rotating shaft, and the other end is fixedly connected to the inner wall of the connecting shaft.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, a closed electrostatic shielding space can be formed by the shielding cover, which isolates the inside of the display screen from the external electrostatic field. The graphite thermal conductive patch can quickly conduct the heat generated inside the display screen, and at the same time play a further shielding role, thereby achieving the effect of quickly shielding and blocking static electricity. This solves the problem of image flickering, discoloration or even component damage caused by external electrostatic field interference, and improves the efficiency of the display screen to work stably in a high electrostatic environment.

[0025] 2. In this utility model, pressing the knob causes the locking post to engage inside the slot, compressing the spring to undergo elastic deformation. Then, rotating the knob causes the locking post to rotate synchronously inside the slot. The elastic restoring force of the spring pushes the limiting ring to contact the outer wall of the locking post, thereby achieving the effect of quickly installing and fixing the shielding cover. This solves the problems of time-consuming installation, cumbersome operation, and easy impact on shielding effect due to improper installation, thus improving installation efficiency.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-4 The present invention provides an embodiment of a display screen with electrostatic shielding function, including a display screen 1, an interface 2 inside the display screen 1, and a shielding component on one side of the display screen 1, the function of which is to shield static electricity;

[0035] The shielding assembly includes a shielding cover 3, which is slidably connected to one side of the display screen 1. The function of the shielding cover 3 is to isolate the interior of the display screen 1 from the external electrostatic field by forming a closed electrostatic shielding space, and to conduct induced static electricity to the ground to prevent electrostatic interference and accumulation. A graphite thermal conductive patch 5 is fixedly connected to one side of the shielding cover 3. The function of the graphite thermal conductive patch 5 is to quickly conduct the heat generated inside the display screen 1 to the outer shell or heat dissipation components, and dissipate heat through air convection and other means to maintain a suitable operating temperature for the display screen 1. Both the shielding cover 3 and the graphite thermal conductive patch 5 have heat dissipation grooves 4 inside. Multiple rubber sheets 6 are fixedly connected to one side of the graphite thermal conductive patch 5. One side of the rubber sheets 6 is in contact with one side of the display screen 1. An antistatic coating 7 is provided on one side of the graphite thermal conductive patch 5. The function of the antistatic coating 7 is to enable the static electricity on the surface of the display screen 1 to be conducted and dissipated in a timely manner, to avoid the accumulation of static electricity on the surface, to reduce the impact on the display screen 1, and to prevent dust adsorption. An installation assembly is provided inside the shielding cover 3, which is used to facilitate quick installation and removal of the shielding cover 3 by the user.

[0036] Specifically, when electronic devices are in environments where static electricity is easily generated and can interfere with and damage internal circuits, components, and display effects, the shielding cover 3 can effectively form a closed electrostatic shielding space, thereby isolating the electrostatic environment inside the display screen 1 from the external environment and preventing external electrostatic fields from interfering with the display screen 1. At the same time, the shielding cover 3 can quickly conduct the static electricity induced inside the display screen 1 to the ground, avoiding the accumulation of static electricity inside the display screen 1, thereby improving the stability and reliability of the device. In order to ensure that the display screen 1 has a suitable temperature during operation, the graphite thermal pad 5 can quickly conduct the heat generated inside the display screen 1 into the surrounding air, and dissipate heat by means of air convection. The static electricity on the surface of the display screen 1 is effectively treated by the antistatic coating 7. The antistatic coating 7 can promptly conduct and dissipate the static electricity accumulated on the surface of the display screen 1, thereby avoiding the adverse effects of static electricity accumulation, such as the impact on the performance of the display screen 1 and the adsorption of dust, thus helping to improve the service life and performance of the display screen 1.

[0037] Reference Figure 5 The mounting assembly includes a fixing block 8 and a connecting shaft 9. One side of the fixing block 8 is fixedly connected to one side of the display screen 1, and the outer wall of the connecting shaft 9 is fixedly connected to the inside of the shielding cover 3. The fixing block 8 and the connecting shaft 9 provide a stable connection and support for the mounting assembly. A slot 10 is provided inside the fixing block 8. The slot 10 cooperates with the locking post 16 to achieve quick locking and unlocking of the mounting assembly. A spring 11 is provided inside the slot 10. The spring 11 uses its elastic restoring force to push the limiting ring 12 tightly against the outer wall of the locking post 16. One end of the connecting shaft 9 is fixedly connected to the inner wall of the fixing block 8, and the other end is fixedly connected to the limiting ring 12, which is made of rubber. A transmission column 13 is slidably connected inside the connecting shaft 9. A rotating shaft 14 is fixedly connected to one end of the transmission column 13, and a knob 15 is fixedly connected to one end of the rotating shaft 14. The knob 15 is used to facilitate the user to quickly drive the movement of the installation component. A locking column 16 is fixedly connected inside the transmission column 13. The locking column 16 engages with the locking groove 10. A second spring 17 is provided on the outer wall of the transmission column 13. One end of the second spring 17 is fixedly connected to one side of the rotating shaft 14, and the other end is fixedly connected to the inner wall of the connecting shaft 9.

[0038] Specifically, when installing the shielding cover 3, firstly, the shielding cover 3 needs to be attached to the fixing block 8 to ensure that the shielding cover 3 can be firmly fixed in the appropriate position. Then, the operator presses the knob 15 to drive the locking post 16 into the slot 10. The locking post 16 rotates synchronously inside the slot 10 by rotating the knob 15. Under the action of pressing, the locking post 16 will further drive the second spring 17 to elastically deform. The elastic deformation of the second spring 17 provides a reverse pulling force to ensure that the locking post 16 can slide smoothly into the slot 10. At the same time, this action will also further compress the first spring 11, forcing the first spring 11 to elastically deform. The restoring force of the first spring 11 makes the limiting ring 12 tightly fit against the outer wall of the locking post 16, thereby restricting the movement of the locking post 16 inside the slot 10, ensuring that the shielding cover 3 is firmly installed in the predetermined position and will not easily loosen. The whole installation process is quick and efficient, making it convenient for users to install and remove the shielding cover 3, reducing the consumption of time and manpower, and improving the ease of use.

[0039] Working Principle: When using the display screen 1, the shielding cover 3 first forms a closed electrostatic shielding space, isolating the inside of the display screen 1 from the external electrostatic field and conducting the induced static electricity to the ground, preventing electrostatic interference and accumulation. The graphite thermal conductive pad 5 quickly conducts the heat generated inside the display screen 1 to the air, dissipating heat through air convection to maintain a suitable operating temperature for the display screen 1. The antistatic coating 7 allows static electricity on the surface of the display screen 1 to be conducted and dissipated in a timely manner, preventing static electricity accumulation on the surface, reducing its impact on the display screen 1, and preventing dust adsorption, thus achieving the effect of electrostatic shielding. When installing the shielding cover 3, personnel first attach the shielding cover 3 to the fixing block 8. Press the knob 15 to engage the locking pin 16 into the slot 10. Then, rotate the knob 15 to make the locking pin 16 rotate synchronously inside the slot 10. Under the pressure, the second spring 17 will elastically deform, and the elastic deformation of the second spring 17 will provide a reverse pulling force to the locking pin 16. As the locking pin 16 slides into the slot 10, it will further compress the first spring 11, causing the first spring 11 to elastically deform. The elastic restoring force of the first spring 11 will push the limiting ring 12 to fit tightly against the outer wall of the locking pin 16, thereby restricting the movement of the locking pin 16 inside the slot 10. This achieves the effect of quickly installing and removing the shielding cover 3, providing convenience for the user.
