1. Introduction
In the field of consumer electronics, with the continuous improvement of display performance requirements for devices such as smartphones and tablets, the performance of optical films has become one of the key factors affecting display quality.

2、 Principle of Nano Structure Control Technology for Huawei Mate 70 Pro AR Anti reflective Film
2.1 Nanoscale microstructure design
The AR anti reflective film of Huawei Mate 70 Pro adopts a unique nanoscale microstructure design, constructing a special microstructure on the surface of the lens. This structure is similar to a 'nanocolumn array', with precise design and optimization of its height, diameter, and arrangement density. The height of nanocolumns is usually in the order of several hundred nanometers, with a diameter of several tens of nanometers, and they are arranged in an ordered or quasi ordered manner. The design principle is based on the theory of light interference and diffraction. When light is incident on the surface of nanostructures, the reflected light between different nanocolumns will interfere. By reasonably controlling the parameters of the nanocolumns, the reflected light can cancel each other out within a specific wavelength range, thereby reducing reflectivity and improving light transmittance.
2.2 Preparation process
In terms of preparation process, the Huawei Mate 70 Pro AR anti reflective film may have adopted advanced nanoimprint lithography technology or atomic layer deposition technology. Nanoimprint lithography technology involves imprinting a template with nano patterns onto the surface of a lens coated with photoresist, and then transferring the nanostructures on the template to the surface of the lens through processes such as development and etching, achieving precise replication of the nanostructures. This process has the advantages of low cost, high efficiency, and large-area preparation. Atomic layer deposition technology involves self limiting chemical reactions of gaseous precursors on the substrate surface, depositing materials layer by layer, and precisely controlling the thickness and composition of nanostructures. This technology can be used to prepare uniform, dense, and high-performance nanostructured layers, ensuring the optical stability of AR anti reflective films.
2.3 Optical Performance Optimization Mechanism
The optical performance optimization of AR anti reflective films mainly relies on the multiple effects of nanostructures on light. On the one hand, nanostructures alter the refractive path of light on the surface of the film layer, reducing the reflection of light at the air film interface. On the other hand, the presence of nanostructures increases the propagation path of light within the film layer, causing multiple reflections and interferences of light within the film layer, further weakening the intensity of reflected light. In addition, the material properties of nanostructures also have an impact on optical performance. By selecting materials with appropriate refractive index to prepare nanostructures, gradient changes in refractive index can be achieved between the film layer, substrate, and air, thereby better matching the requirements of light propagation and optimizing optical performance.
3、 Huawei Mate 70 Pro AR Anti reflective Film Technology Breakthrough and Performance Performance
3.1 Reflectance reduction
The AR anti reflective film of Huawei Mate 70 Pro has made significant breakthroughs in reducing reflectivity. In the visible light range (400-700nm), its reflectivity can be reduced to below 1%. Compared to regular mobile phone lenses, the reflectivity has decreased by 10% -15%. This achievement effectively reduces glare and ghosting caused by light reflection, improving the imaging quality of the lens in complex lighting environments. Under strong light, the captured images are clearer and sharper, with higher color reproduction, allowing users to have a better shooting experience.
3.2 Enhancement of Light Transmittance
With the decrease of reflectivity, the transmittance of AR anti reflective film has been significantly improved. High transmittance allows more light to pass through the lens and enter the sensor, improving the camera's sensitivity. In low light environments, the noise in photos taken by mobile phones is reduced, resulting in brighter and clearer images, effectively enhancing the phone's ability to capture night scenes. At the same time, for display screens, high transmittance can make the displayed image more transparent, the colors more vivid, and enhance the user's visual experience.
3.3 Durability and Stability
In addition to the improvement of optical performance, the AR anti reflective film of Huawei Mate 70 Pro also has good durability and stability. By optimizing the preparation process and material selection of nanostructures, the hardness and wear resistance of the film layer have been enhanced, which can effectively resist scratches and wear in daily use. At the same time, the film layer has good chemical stability and can resist the erosion of pollutants such as water vapor and oil stains. Long term use is not prone to performance degradation, ensuring that the AR anti reflective film can perform well throughout the entire life cycle of the mobile phone.
4、 Enlightenment on the Innovation of Display Optical Films
4.1 Design Concept Innovation
The nanostructure control technology of Huawei Mate 70 Pro AR anti reflective film has brought a new concept to the design of display optical films. Traditional display optical films often achieve anti reflection effects by stacking multiple layers of thin films, while nanostructure control technology innovates at the microscopic level. The design of future display optical films can draw inspiration from this approach, by precisely designing nanoscale microstructures to achieve precise control over light propagation, in order to achieve better optical performance. For example, in the design of CPI optical film for foldable OLED display screens, similar nanostructures can be introduced to optimize the reflection and transmission characteristics of the film layer towards light, thereby improving the display effect of the screen.
4.2 Innovation in Preparation Process
The advanced preparation processes used in this technology, such as nanoimprint lithography and atomic layer deposition, provide a new direction for the large-scale production of display optical films.

The new preparation process has advantages such as high precision, high efficiency, and low cost, which can meet the needs of large-scale production of display optical films. In practical production, these processes can be applied to the preparation of different types of display optical films, such as optical films for automotive instrument panel displays, VR/AR equipment, etc., to improve production efficiency and product quality. Meanwhile, through process innovation, the multifunctionality of optical films can also be achieved, such as integrating hydrophobic and anti fingerprint functions during the preparation process.
