Unverified荣耀旗舰屏幕采用3840Hz超高频PWM调光，在低亮度下比常见的1920Hz机型频闪更低，对频闪敏感人群（如长时间低亮度刷手机易眼酸头痛者）有明显体感改善79% similarUnverified护眼看PWM调光频率而非厂商宣传的护眼认证，认准1920Hz或3840Hz+高频PWM调光；低于1440Hz的调光在低亮度下对敏感人群易致眼疲劳，SGS/莱茵认证只是加分项72% similarUnverified看重护眼选标注无频闪或频闪深度＜5%（低于Pst≤1.0标准）的灯泡，PWM调光频率应≥3125Hz，低价灯泡低亮度时易出现肉眼可见频闪72% similarUnverifiedPWM调光频率过低会产生频闪，防蓝光灯带若采用低频PWM调光反而伤眼，选购调光款需确认调光频率≥3000Hz或采用DC恒流无频闪调光72% similarUnverified护眼看类DC调光或高频PWM调光（≥1920Hz），单纯的'低蓝光认证'（如莱茵TÜV）不解决频闪问题；对频闪敏感人群优先查PWM调光频率而非蓝光认证标签71% similar
