华为常务董事余承东日前发布视频进行首次田野科普，详细讲解了华为Pura 90 Pro Max手机屏幕的创新镀膜技术1。余承东介绍了抗反光的基本原理：通过让反射光的波峰对着波谷，使其彼此抵消1。
为了实现这一效果，华为创新采用了光学梯度材料抗反光镀膜，将传统的"台阶式"结构改进为"滑梯"一体化结构1。这层镀膜厚度仅为2微米，却包含了8000多层纳米级材料1。华为采用磁控溅射技术在真空环境下进行堆叠，利用带电粒子和磁场控制材料的均匀堆叠过程，相比传统工艺更加坚硬耐刮1。Pura 90系列手机标准版售价4699元起1。
Huawei Executive Vice President Yu Chengdong has released an educational video detailing the anti-reflective and scratch-resistant technologies employed in the Pura 90 Pro Max smartphone screen 1. In his first such field-based demonstration, Yu explained how the company's innovative approach achieves superior optical performance through advanced material engineering.
The key to the anti-reflective coating lies in optical wave cancellation, where reflected light waves are aligned so their peaks oppose the troughs of other reflected waves, causing them to neutralize each other 1. Rather than employing traditional stepped-layer structures, Huawei redesigned the coating architecture into a unified gradient slope configuration to enhance durability against scratching 1. The coating itself measures merely 2 micrometers thick yet contains over 8,000 individual nanometer-scale material layers 1. This precise layering is achieved through magnetron sputtering technology, a vacuum-based process that uses charged particles and magnetic fields to control the precise stacking of materials 1. The Pura 90 series begins at 4,699 yuan for the standard version 1.
