230 mesh irregular shielding film is a thin film material used for liquid crystal display (LCD) screens

    230 mesh irregular shielding filmIt refers to a method of preparing thin films with micrometer level structures. Among them, 230 mesh refers to the aperture size on the shielding plate being 230 mesh, which is approximately 60 microns.

In the process of preparing 230 mesh irregular shielding film, it is necessary to first coat a layer of photoresist on the substrate surface. Then, place a 230 mesh irregular shielding plate on the photoresist and expose it to ultraviolet light to form a hole pattern. Next, the hole pattern is transferred to the substrate surface using chemical etching or ion beam etching to form micrometer level structures. Finally, the required thin film material is deposited on the substrate surface through physical vapor deposition, sputtering, and other methods to form a 230 mesh irregular shielding thin film.

230 mesh irregular shielding film is a thin film material used for liquid crystal display (LCD) screens. Its main function is to shield the electromagnetic radiation and external light source interference on the LCD screen, improving the clarity and stability of the display screen.

such Shielding filmThe characteristic of it is that its shielding structure is an extremely small irregular metal structure, which can effectively eliminate interference by passing noise signals in different frequency ranges.

230 mesh irregular shielding film is generally manufactured from glass or plastic substrates through processes such as vacuum evaporation, photolithography, and etching. The material has extremely high transparency and will not affect the normal display of the screen. At the same time, it can effectively prevent the intrusion of ultraviolet and other harmful light, which also plays a good role in protecting the visual safety of users.

At present, 230 mesh irregular shielding film has been widely used in various electronic devices that require shielding and protection, especially in high-end consumer electronics fields such as smartphones, tablets, and e-books, becoming an essential advanced screen protection material.
