**Abstract**
Zhejiang Shangcheng Technology Co., Ltd. has recently announced the successful development of its next-generation mobile phone protection screen, crafted entirely from sapphire crystal. As the world’s only sapphire-based phone screen protector, this innovation is set to revolutionize the market by breaking away from the traditional "protective film" era and ushering in a new age of durable, stylish, and health-conscious mobile device protection.
Industry experts believe that sapphire, known for its exceptional hardness, scratch resistance, and chemical stability, is poised to become a key material in high-end smartphone manufacturing. With its superior mechanical strength, thermal conductivity, and optical clarity, sapphire has already found applications in aerospace, military, and medical industries. In recent years, it has also gained popularity in consumer electronics, including high-end smartphones, smartwatches, and camera lenses.
Currently, most phone screen protectors on the market are made from polymer materials like PC, PVC, or PET. While they come in various types, they all have their limitations—some lack sensitivity, others cause fingerprint smudges or rainbow effects, and some even damage the screen over time due to chemical corrosion or heavy metal content. Most importantly, these films only protect the screen surface and do little to enhance the phone's overall durability.
In short, no existing screen protector fully meets the demands of modern users. The introduction of the sapphire-based screen protector from Zhejiang Shangcheng aims to address these shortcomings by offering comprehensive protection, enhanced touch performance, and improved health benefits.
First and foremost, sapphire offers unmatched protection. With a hardness rating of 9 on the Mohs scale—second only to diamond—it provides excellent impact resistance and scratch resistance, significantly reducing the risk of cracked screens. Its high thermal conductivity allows faster heat dissipation, while its chemical stability ensures long-term durability even under harsh conditions.
Secondly, the sapphire screen protector boasts ultra-high optical transmittance and minimal light scattering, delivering vibrant colors and a clear, mirror-like display. It also enhances touch sensitivity, providing a smoother and more responsive user experience.
What stands out most is the product’s focus on health and safety. With twice the radiation resistance of regular glass, it helps reduce electromagnetic radiation exposure, especially to the brain. This makes it not just a protective layer, but a healthier choice for daily use.
Additionally, the sapphire screen protector breaks the mold of traditional screen protectors by adding a unique, personalized touch. Its luxurious appearance, similar to diamond, has already been adopted by top luxury brands such as Ferrari, Lamborghini, and Vertu. Known as the "never-wear-out" glass, it has become a symbol of prestige and value retention.
Shangcheng Technology began researching sapphire-based screen protectors back in October 2011, and after 13 months of development, the product is now ready for mass production. Currently, orders from mobile phone accessory manufacturers are pouring in, and the product is expected to launch in the first quarter of next year.
