Apple Awarded Patent for New Transparent Cover Glass with Multilayer Structure Enhancing Durability and Outdoor Display Performance

On March 20th, tech media outlet Patently Apple reported that Apple Inc. was recently granted a patent for a new transparent cover glass technology for iPhones and iPads. This patented technology utilizes a sophisticated multilayer composite structure design to significantly enhance the screen's scratch and abrasion resistance while effectively reducing screen glare, thereby improving the user experience in outdoor environments. This breakthrough technology is poised to revolutionize mobile device screen protection and display performance, delivering a superior visual experience for users.

The patent describes the new transparent cover glass technology as not a simple single-layer glass structure, but rather a multi-layer composite design that overcomes the limitations of traditional glass technologies. This multilayer structure enhances screen durability while maintaining excellent display quality.

The outermost layer is a crucial hard-wearing coating. This layer, made of a high-strength material such as siliconoxynitride, forms a robust protective layer effectively preventing scratches and abrasion. Compared to traditional silicon dioxide coatings, siliconoxynitride offers superior hardness and wear resistance, better withstanding the damage caused by daily use and extending the screen's lifespan. Traditional silicon dioxide coatings, due to their lower hardness, are prone to scratches and wear, affecting the visual quality and user experience. Apple's patent innovatively addresses the problem of easily worn silicon dioxide coatings, providing more reliable screen protection.

Beneath the hard-wearing coating is an embedded interference layer. This layer consists of multiple materials, including siliconoxynitride and silicon dioxide. By precisely controlling the optical constants and thickness of these materials, and utilizing the principle of light interference, screen glare is effectively reduced. Under direct sunlight, screen glare severely impacts readability and viewing, diminishing the user experience. This patented technology, through its interference layer design, effectively reduces glare, ensuring clear visibility even in bright outdoor conditions and enhancing the outdoor user experience. This is a major highlight and a significant advantage of the patent.

To further enhance structural reliability and stability, a gradient layer is included in the patent. Located between the glass substrate and the hard coating, the gradient layer acts as a buffer and transition, connecting the glass substrate and the hard coating materials, thereby strengthening the overall structural stability and reliability and preventing delamination or damage from external impacts. This design cleverly combines the properties of various materials, achieving the optimal balance between screen protection and display performance.

Furthermore, the patent's mention of a thicker intermediate hard coating is noteworthy. This design effectively resists deep scratches, preventing damage to the glass substrate and further enhancing screen durability. Deep scratches not only affect aesthetics but also degrade display performance and may even lead to screen failure. The thicker hard coating effectively blocks deep scratches, ensuring the long-term stable operation of the screen.

While this patented technology currently targets iPhones and iPads, its application isn't limited to these products. In the future, this technology could be extended to other Apple devices such as the Apple Watch, providing a superior screen experience for a wider range of Apple users. Its application will potentially improve the scratch and abrasion resistance and outdoor display performance of all Apple device screens.

In conclusion, Apple's new transparent cover glass patent, through its ingenious multilayer composite structure design, has made significant progress in enhancing screen durability and outdoor display performance. The technology employs multiple innovative measures, including high-strength abrasion-resistant materials, an anti-reflective interference layer, and a gradient layer to enhance structural stability, effectively addressing the shortcomings of traditional glass technology in scratch resistance, abrasion resistance, and outdoor display. This brings a superior user experience. The application of this technology signals a new stage in mobile device screen technology. Apple's continuous pursuit of technological innovation is evidenced by this patent, and we can expect its application in more Apple products in the future, delivering even more exceptional technological experiences. Apple's strong R&D capabilities and innovative strength continue to lead the industry and surprise users. The successful development and application of this patented technology further solidifies Apple's technological leadership in the mobile device field. This technology not only enhances user experience but also provides new ideas and references for the future development direction of mobile device screen technology. We can expect more similar technological innovations to drive continuous progress in mobile device screen technology, bringing users more convenient and comfortable experiences.
