亮度越高瞬时功耗越大，LTPO无法降低高亮度下的功耗；经常户外强光使用者应更看重屏幕能效等级(同亮度下功耗)而非单纯低刷能力

Unverified低亮度环境下的调光方式比LTPO更影响护眼与省电体验：高频PWM(≥1920Hz)或类DC调光对敏感人群更重要，选LTPO机型时应同时确认低亮度调光频率83% similarUnverified亮度越高越费电，长续航与高亮度不可兼得；实际使用建议选带多档调光的型号，高亮找路、低亮长时间氛围照明分场景切换79% similarUnverified深防眩设计牺牲出光效率：灯珠越深藏、蜂窝网越密，眩光越低但实际照度衰减越多，需相应提高瓦数补偿；不能既要极致防眩又要小功率省电79% similarUnverified亮度越亮往往色温精度和显色越难兼顾，直播/固定场景选大直径高亮款，外出Vlog应牺牲亮度选可USB/电池供电的便携小灯78% similarUnverified低频PWM调光(如某些机型高亮下降频)与LTPO低刷叠加时，敏感人群在低亮度低刷场景更易感到频闪不适，护眼敏感者应确认全亮度全刷新率下的调光策略而非仅看峰值PWM频率78% similar
