In daily use, Curved touch screens are inevitably subject to accidental scratches from sharp objects such as keys and coins. How to ensure that curved touch screens have good scratch resistance while maintaining their appearance has become a common concern for manufacturers and users.

1.Progress in Materials Science of Curved touch panel

• New Glass Materials

Traditional glass has high hardness but is fragile, making it unsuitable for direct use in curved surface design. Therefore, the development of new glass materials that have both high hardness and good bending ability has become crucial.

• Nanocomposite materials

The application of nanotechnology has brought revolutionary changes to curved touch screen materials. By embedding nanoparticles into screen materials, their wear resistance and scratch resistance can be significantly improved. These nanoparticles form a protective film at the microscopic level, effectively resisting scratches from sharp external objects.

• Elastic polymer layer

In the design of some curved touch panel, a highly elastic polymer layer is added as a buffer. This layer of material can not only absorb impact force, but also self repair minor scratches to a certain extent, thereby extending the service life of the screen.

2.Innovation in surface treatment technology of Curved touch panel

• Chemical reinforcement

By chemical treatment of the glass surface, such as ion exchange process, a compressive stress layer can be formed on the glass surface. This stress layer can effectively resist external impacts and scratches, improving the durability of the screen.

• Coating technology

Applying a scratch resistant coating on the surface of the screen is a direct method to improve its scratch resistance performance. High quality scratch resistant coatings not only have high hardness, but also have good transparency and wear resistance, which can effectively protect the screen from scratch damage without affecting the display effect.

• Texture processing

By applying fine texture treatment to the screen surface, it is possible to increase the frictional resistance of the screen surface and reduce the occurrence of scratches without sacrificing touch sensitivity. This processing method enhances the actual durability of the screen while maintaining its aesthetic appeal.

3.Optimization of structural design of Curved touch panel

• Edge buffer design

The edge of a curved touch screen is the most susceptible area to scratching. By designing clever edge cushioning structures, such as using curved edges or increasing the thickness of edge materials, the wear of edge areas can be effectively reduced and the overall scratch resistance can be improved.

• Multi layer structure design

By adopting a multi-layer composite structure, different functional material layers are stacked together, which not only utilizes the advantages of each layer of material, but also enhances the overall scratch resistance through the interaction between layers. For example, combining a high hardness glass layer with an elastic polymer layer not only ensures the rigidity of the screen, but also increases its flexibility.

• Design of replaceable protective film

In the design of some curved touch screens, consideration is given to users' personalized needs for scratch resistance, and replaceable protective films are provided. These protective films are usually made of highly wear-resistant materials, and users can replace them regularly according to their usage to maintain the cleanliness and scratch resistance of the screen.
