OLED 頻閃

看了一些OLED關於眼睛舒適的文章

提到OLED藍光是比LCD還低，越低越無害是沒什麼異議的

但查了一下PWM的文，除了2019年前的文章會比較常提到亮度低時螢幕會閃爍(手機、電視)

2019年後的幾乎沒有提到了，去rting查LG C9 PWM也顯示0hz，意思大概是無背光所以也沒有頻閃?

LG之前爬文也顯示面板不是用的PWM技術，但也沒特別說用的什麼還是不用使用

根據文章

Most LCD TVs use LEDs, too, but usually the brightness levels are regulated by PWM (pulse width modulation) – aka, flicker. As reported by TV, gaming and media publication FlatpanelsHD, TÜV Rheinland found that LG Display's OLED panels passed its tests for flicker, while further tests have found the panels to be almost flicker-free.

The testers found that LG Display's OLED TV panels consist of 34 per cent blue light, lower than the 50 per cent threshold. LG Display said, "while the highest spec 65-inch LCD panels produce 64 per cent blue light, LG Display’s OLED panels emit only half that amount".

這還說萊茵認證無頻閃(但也沒說是不是在特定亮度或條件下)


不知道有技術高手知道目前OLED頻閃的狀況大概是什麼情形嗎?
