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].
