Apple supplier breaks through AR glass nano coating technology, reducing reflectivity to below 0.5% to help upgrade MR device display

Recently, Apple's major suppliers have successfully overcome the challenge of AR glass nano coating technology, reducing the glass reflectivity to below 0.5%, bringing significant breakthroughs to the improvement of display effects for Apple MR (mixed reality) devices. This achievement is not only expected to significantly improve user experience, but also to drive technological upgrades in the entire MR industry.

The nano coating technology of AR glass is achieved by coating one or more nano level optical films on the surface of the glass, using the principle of light interference to reduce reflectivity and improve transmittance. The reflectivity of ordinary glass is usually around 8%, which can cause severe interference of ambient light reflection on the display of virtual images in the use of MR devices, reducing image clarity and contrast, and affecting users' immersion in virtual scenes. Through advanced nano coating technology, it is possible to effectively reduce reflected light and enhance transmitted light intensity. The technological breakthrough achieved by Apple suppliers this time has reduced the reflectivity to below 0.5%, far exceeding the industry average, which means that MR devices can present clearer and more realistic virtual images in various lighting environments.

Conquering this technology is not an easy task. The process of nano coating requires extremely high precision, requiring precise control of the thickness, composition, and uniformity of the film. Even extremely small deviations can lead to a significant reduction in the optical performance of the film layer. For example, if the thickness deviation of the film layer exceeds the nanometer level, it is impossible to accurately achieve interference cancellation of reflected light, and the expected anti reflection effect cannot be achieved. To solve these problems, Apple suppliers have invested a lot of research and development resources, adopting advanced magnetron sputtering technology and high-precision automation equipment. Through continuous optimization of process parameters and countless experiments, they have successfully achieved a significant reduction in reflectivity and stability of the coating process.

For Apple's MR devices, this technological breakthrough is of great significance. Taking the Apple Vision Pro as an example, although its display performance has been leading, there is still a certain degree of reflection problem in strong light environments, which affects the visual effect of the integration of virtual and reality. Nowadays, with the use of AR glass with reflectivity reduced to below 0.5%, devices can more clearly overlay virtual information on real scenes. Whether it is complex 3D model display or delicate virtual scene construction, they can present unprecedented clarity and realism, greatly enhancing users' immersive experience and further consolidating Apple's leading position in the MR market.

From an industry perspective, the technological breakthroughs of Apple suppliers have a guiding significance. On the one hand, it will encourage other MR equipment manufacturers to increase their investment in AR glass technology research and development, promote continuous innovation in display technology throughout the industry, and drive the development of related industrial chains, such as optical materials, coating equipment, and other fields, which will usher in new opportunities. On the other hand, with the maturity of technology and the reduction of costs, more consumers are expected to enjoy high-performance MR devices at more reasonable prices in the future, accelerating the popularization and application of MR technology in more fields such as education, healthcare, and entertainment, and opening a new chapter in the development of mixed reality technology.
