Description

Technical Field

[0001] This utility model relates to the field of LCD display technology, and in particular to a metal mesh shielding cover for LCD displays that prevents electrostatic interference. Background Technology

[0002] LCD displays, or liquid crystal displays, are screens that use liquid crystal technology to display images or text. They are widely used in various electronic devices such as televisions, computer monitors, mobile phones, and dashboards. In order to prevent external electromagnetic interference or protect the internal circuitry and liquid crystal layer of an LCD display from damage, a metal mesh or metal material is usually used to make a shield.

[0003] However, most existing LCD display shielding covers only employ an anti-static coating for electrostatic discharge (ESD) protection, resulting in poor ESD performance and potential damage to the display screen under high static electricity conditions. Therefore, those skilled in the art have developed an ESD-resistant metal mesh shielding cover for LCD displays to address the problems mentioned in the background section. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a metal mesh shielding cover for an LCD display screen that prevents electrostatic interference, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a metal mesh shielding cover for an LCD display screen to prevent electrostatic interference, comprising: a metal cover and a metal mesh disposed inside the metal cover, a shielding cover disposed on the rear surface of the metal cover, and an electromagnetic shielding film disposed on the rear surface of the metal cover in front of the shielding cover, a grounding plate also being installed on the outer side of the metal cover, and both the front surface of the metal cover and the rear surface of the shielding cover being coated with an antistatic coating.

[0006] As a further technical solution of this utility model, the grounding plate is installed on the outside of the metal cover by a second bolt.

[0007] As a further technical solution of this utility model, the front surface of the metal cover is also provided with a first bolt, and the shielding cover is connected to the metal cover by the first bolt.

[0008] As a further technical solution of this utility model, the materials of both the metal cover and the shielding cover are copper.

[0009] As a further technical solution of this utility model, the metal mesh has a square mesh structure.

[0010] As a further technical solution of this utility model, the material of the antistatic coating is a graphite coating.

[0011] As a further technical solution of this utility model, the material of the electromagnetic shielding film is aluminum.

[0012] This invention provides a metal mesh shielding cover for an LCD display screen that prevents electrostatic interference, and has the following advantages compared with the prior art:

[0013] 1. This design provides an anti-static interference metal mesh shielding cover for an LCD display screen. By installing a shielding cover on the rear surface of the metal cover to increase its thickness, the shielding capability against electromagnetic interference can be effectively improved. Furthermore, the grounding plate can transmit static electricity to the ground through a conductor, preventing static electricity from affecting the operation of the LCD display screen. The design is simple in structure and highly practical.

[0014] 2. This design provides an anti-static interference LCD display screen metal mesh shielding cover. By placing an electromagnetic shielding film between the metal cover and the shielding cover, electromagnetic interference and electrostatic interference are effectively suppressed, thereby improving the display effect and the stability of the equipment. At the same time, an anti-static coating is applied to the outside of the metal cover and the shielding cover, which enhances the anti-static capability of the metal mesh shielding cover and avoids the influence of static electricity on the display screen.

[0024] Please see Figure 1-3 This utility model provides a technical solution for an anti-static interference LCD display screen metal mesh shield: including: a metal cover 1 and a metal mesh 4 disposed inside the metal cover 1, a shield 2 disposed on the rear surface of the metal cover 1, and an electromagnetic shielding film 6 disposed on the rear surface of the metal cover 1 in front of the shield 2, a grounding plate 3 also being installed on the outer side of the metal cover 1, and an antistatic coating 5 being coated on the front surface of the metal cover 1 and the rear surface of the shield 2.

[0025] like Figure 1 As shown, the grounding plate 3 is installed on the outside of the metal cover 1 by the second bolt. This arrangement allows static electricity to be transferred to the ground through the metal cover 1 using the grounding plate 3, thus preventing static electricity from affecting the operation of the LCD display.

When installing the electromagnetic shielding film 6, the metal cover 1 and the shielding cover 2 can be connected by the first bolt 11. After connection, an antistatic coating 5 is applied to the outside of the metal cover 1 and the shielding cover 2. In this way, the antistatic coating 5 can enhance the antistatic ability of the metal mesh shielding cover 2 and avoid the influence of static electricity on the display screen. At the same time, the grounding plate 3 is installed on the outside of the metal cover 1 by the second bolt. In this way, the static electricity can be transmitted to the ground through the metal cover 1 using the grounding plate 3, so as to avoid the static electricity affecting the operation of the LCD display screen and ensure the normal use of the LCD display screen.
