介意屏幕烧屏和频闪的选高频PWM调光：OLED直屏应选PWM调光频率≥1920Hz（部分达2160/3840Hz）机型，低频调光（480Hz以下）长时间使用眼睛易疲劳

Unverified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90% 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89% 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88% 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88% similarUnverified调光方式优先选PWM频率>3000Hz或DC直流调光的产品，低频PWM（<1250Hz）在低亮度时频闪严重，长期使用引起眼疲劳88% similar
