The connection between the first diaphragm and the second diaphragm and the connection between the second diaphragm and the third diaphragm are both provided with a coating, and the coating includes a super-hydrophobic primer, a super-hydrophobic middle paint and a super-hydrophobic top paint. The super-hydrophobic primer is coated on the upper surface of the third diaphragm, and the super-hydrophobic middle paint is coated on the upper surface of the super-hydrophobic primer." When in use, the liquid crystal display is hydrophobically protected by multiple layers of super-hydrophobic coatings, but in the superposition of multiple layers of super-hydrophobic coatings, the inner layer of the super-hydrophobic coating is difficult to play a role, which not only wastes materials, but also when encountering scratches, the multiple layers of super-hydrophobic coatings are easily scraped off together, making it difficult to provide good protection for the liquid crystal display.

[0004] Therefore, we provide a super-hydrophobic bionic nano-coating liquid crystal display to solve the above problems. Utility Model Content

At the same time, the thermal insulation coating is less affected by the physical changes caused by external environment such as heat and humidity, and can effectively block infrared radiation and ultraviolet radiation, stabilize the use of the LCD screen, and contain Si nanocrystalline composite coatings. While effectively improving the high temperature resistance, it also increases the wear resistance of the LCD screen surface. Combined with micron- and nano-scale structures, these coatings can provide more stable super-hydrophobic properties. The scaly bionic structure can make the super-hydrophobic coating have better self-cleaning properties and avoid the residue of water vapor and dust.

[0024] Furthermore, the buffer spring 2 is fixedly connected to the shell 1, and the buffer spring 2 is evenly distributed at equal distances on the inner side of the shell 1. The inner slot of the buffer spring 2 is connected to the damping component 3. The damping component 3 and the buffer spring 2 are in one-to-one correspondence. When the display screen is accidentally hit, the buffer spring 2 will immediately be compressed and contracted, so that there is a buffer space for the LCD screen 5 in the shell 1, thereby reducing the factors of damage to the LCD screen 5 by impact.

[0025] Furthermore, the protective outer frame 6 is welded to the shell 1, and the inner surface of the protective outer frame 6 is made of soft rubber material. The thickness of the protective outer frame 6 is greater than the thickness of the LCD screen 5. The edge of the LCD screen 5 is protected by the soft rubber material. At the same time, the thickness of the protective outer frame 6 is higher than that of the LCD screen 5, thereby reducing the damage of the LCD screen 5 by scratches from the outside.

[0026] Furthermore, both the inner adhesive coating 7 and the outer adhesive coating 9 are optically applied nano-composite coatings, the thickness of the inner adhesive coating 7 is 15 to 20 nm, and the thickness of the outer adhesive coating 9 is 12 to 15 nm.

The thickness of the thermal insulation coating 8 is 0.01 to 0.05 mm. The nano-tungsten oxide has stable chemical properties and is less susceptible to physical changes caused by external environments such as heat and humidity. It can effectively block infrared radiation and ultraviolet radiation, thereby improving the stability of the liquid crystal display 5.

[0028] Furthermore, the wear-resistant coating 10 is a nanocrystalline composite coating, and the thickness of the wear-resistant coating 10 is 10-12 nm.

[0030] Working principle: When in use, the first step is to spray the surface of the liquid crystal display screen 5 with an optically applied nano-composite coating to make its surface smoother. Then, the thermal insulation coating 8 has little physical change caused by external environment such as heat and humidity, and can effectively prevent infrared radiation and ultraviolet radiation, and stabilize the use of the liquid crystal display screen 5. The second step is to use a nanocrystalline composite coating containing Si to effectively improve the high temperature resistance while increasing the wear resistance of the surface of the liquid crystal display screen 5. At the same time, combined with micron- and nano-scale structures, these coatings can provide more stable super-hydrophobic properties. At the same time, the scaly bionic structure can make the super-hydrophobic coating 11 have better self-cleaning properties, avoiding the residue of water vapor and dust. The third step is that during use, if the display screen is accidentally hit, the buffer spring 2 will be compressed and contracted immediately, so that there is a buffer space for the liquid crystal display screen 5 in the shell 1, reducing the factors of damage to the liquid crystal display screen 5 by impact, thus completing the use process of a super-hydrophobic bionic nano-coated liquid crystal display screen.
