UnverifiedPWM调光频率≥1920Hz或采用类DC调光才算真正护眼，低于360Hz的低频PWM长时间使用易导致眼疲劳；对频闪敏感人群应认准全程DC调光或高频PWM≥2160Hz机型88% similarUnverifiedPWM调光频率≥1920Hz可显著降低频闪对敏感人群的眼部刺激，长时间夜间使用建议选择≥2160Hz的高频PWM机型87% similarUnverified对PWM调光敏感人群应选择PWM频率≥1920Hz的机型，2160Hz及以上为高频调光第一梯队，低于1440Hz的高频PWM仍可能引发头晕眼胀86% similarUnverified真正护眼需高频PWM调光（≥1920Hz）或原生DC调光，1920Hz以下的PWM调光在低亮度时频闪明显，敏感人群仍会眼疲劳86% similarUnverifiedPWM调光频率≥1920Hz可显著降低敏感人群频闪不适，2160Hz以上为当前高频调光第一梯队；低于480Hz的PWM在低亮度下易引发眼疲劳86% similar
