Oled的閃爍問題不只要看頻率,還得看波動深度才能判斷是否傷眼
IEEE給出的護眼標準如果波動深度100%,那PWM要3125hz以上才不會傷眼
https://i.imgur.com/1DbAa9M.jpg
60hz的時候波動深度要低於3%
240hz 要低於19%
360hz 要低於28.8%
480hz 要低於 38%
而13系列全局480hz 波動深度達到90%以上,會不會傷眼自行判斷
很多人眼睛看Oled會累會酸就是低頻率又超高波動深度,你用慢速攝影機拍都是又粗又黑的
橫紋在上面,會酸的還幸運,眼睛還能反應讓人知道,有些自己看無感結果幾年後散光眼壓
年年上漲那才慘
隔壁中國面板廠商在Oled上對於護眼主要的攻克點是高頻PWM與類DC
高頻率PWM可以容忍的波動深度很高,目前京東方的面板已經到了1920hz
類DC調光頻率通常都很低,但波動深度同樣可以非常低,所以類DC不代表護眼,如果是60hz
的類DC那它的波動深度測出來也要低於3%,而這也只是低風險,要無風險還是高頻率PWM或者
無閃爍才安全
中國那邊很多對於Oled螢幕閃爍方面進行專業的測試,而台灣這邊好像蠻少關注這個問題的
,廠商對於Oled只會宣傳它的優點,缺點消費者自己得去注意,尤其涉及到健康層面
