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93% similarUnverifiedPWM调光频率＜1250Hz的OLED屏对敏感人群可能引发眼疲劳，选购护眼需认准≥1920Hz高频PWM或类DC调光，2160Hz以上为第一梯队91% similarUnverified真正无频闪需认准DC调光而非高频PWM调光，PWM调光频率≥3840Hz才能基本消除频闪对眼睛的影响，低于此值长时间使用易疲劳91% similarUnverified护眼看重防频闪时优先选高频PWM调光≥1920Hz或全程DC调光机型，低频PWM（240Hz/480Hz/720Hz）在低亮度下频闪明显，敏感人群会头晕眼胀91% similarUnverified屏幕看PWM调光频率而非峰值亮度：对屏幕敏感/易眼疲劳者选高频PWM（≥1920Hz）或类DC调光机型，OLED低频闪烁是暗光下眼干头晕的主因90% similar
