原文:
Here's the relevant part, emphasis mine:

The display backlight flickers at 290.7 Hz (Likely utilizing PWM) Flickering
detected at a brightness setting of 99 % and below. There should be no
flickering or PWM above this brightness setting.
顯示背光以290.7 Hz的頻率閃爍，在99％或更低的亮度會檢測到
閃爍。在此亮度設置以上，不會出現閃爍或PWM。

The frequency of 290.7 Hz is relatively high, so most users sensitive to PWM
should not notice any flickering. However, there are reports that some users
are still sensitive to PWM at 500 Hz and above, so be aware.
290.7 Hz的頻率相對較高，因此大多數對PWM敏感的用戶都不會注意到任何閃爍。但是，
有報告稱某些用戶仍然對500 Hz及以上的PWM敏感，因此請注意。

I believe all their reviews are translated, so ignore any quirky language.

Here's a comparison:

iPhone 11 Pro: 290.7 Hz @ < 100% brightness

iPhone Xs: 240.4 Hz @ < 100% brightness

iPhone X: 240.4 Hz @ < 100% brightness

notebookcheck測試出來今年iphone 11 PRO PWM 提升至290.7Hz
相比去年240.4Hz增加了不少
這邊放一下近期旗艦OLED數據做一下對比:
(來源:https://dev1.notebook-check.com/index.php?id=163979 )


Model Screen Resolution Screen Type PWM Frequency
Apple iPhone 11 Pro 2436x1125 OLED 290.7
Apple iPhone 11 1792x828 IPS 0
Apple iPhone XS 2436x1125 OLED 240.4
--------------------------------------------------------------------
安卓旗艦陣營對比
Samsung Galaxy Note10+ 3040X1440 Dynamic AMOLED 250
HTC U12 Plus 2880X1440 Super LCD 9709
SONY X1 3840x1644 OLED 245.1
OnePlus 7 Pro 3120X1440 AMOLED 122


對比一下陣營除了IPS螢幕外
OLED PWM最高的應該就是290.7的iphone 11 pro了,蘋果這次的提升應該
可以減緩對OLED所造成的疲勞
