Unverified选购时应区分类DC调光模式和硬件级DC调光：红米/iQOO中端机型多为高频PWM方案而非真正DC调光，购买前需确认调光方式而非仅看宣传护眼标签90% similarUnverified如果核心诉求是纯DC调光零频闪，OPPO Find/Reno系列的高频PWM方案并不等同于DC调光，选购前需区分两者原理差异79% similarUnverified哺乳灯优先选用DC调光或高频PWM调光的产品，低频PWM调光在低亮度档位频闪最明显，恰是夜哺常用档位，用手机相机检测低档而非高档才能发现问题79% similarUnverified类DC调光（DC-like）本质仍是PWM+算法降频，在中低亮度下频闪深度低于纯PWM但高于真DC，属于OLED的折中方案，宣传时需区分是否为全亮度覆盖79% similar
