Ultra-Hard AR Coating Solutions for Smartphones, Automotive, and Industrial Displays
Introduction
The most striking technological iteration in the consumer electronics sector in 2025 is undoubtedly the “Ultra-Hard AR Coating.” Industry sources indicate that the iPhone 17 and Huawei Mate 80 are highly likely to feature ultra-hard AR coatings across all models. With the rapid development of smartphones, automotive displays, and industrial windows, high-transmittance, low-reflection, and high-durability display windows have become key requirements for enhancing user experience. Thanks to its exceptional optical performance and durability, ultra-hard AR coating technology is emerging as a core solution for mobile phone cover glass, automotive displays, and industrial windows.
1. Overview of Ultra-Hard AR Coating Technology
Ultra-Hard Anti-Reflective (AR) Coating is an advanced optical thin-film technology. It deposits multiple layers with precisely controlled thicknesses and different refractive indices onto glass or transparent plastic substrates. By inducing destructive interference of light waves, it significantly reduces reflection, enhances transmittance, and improves surface hardness and wear resistance.
Technical Principles:
-
Layer thickness is typically designed as one-quarter of the target wavelength (λ/4)
-
Two reflected waves form a 180° phase difference → mutual cancellation
-
Reduces screen reflectivity from traditional 8% to below 1%, improving visibility under bright light by approximately 3 times
-
Coating hardness reaches Mohs 7 (approaching sapphire), increasing scratch resistance by roughly 50%
Application Scenarios:
-
Mobile phone cover glass: Enhances sunlight readability and touch experience
-
Automotive displays: Durable screens for central control panels, HUDs, etc.
-
Industrial/commercial windows: High-end industrial displays and information terminals
