Ok, 接上楼。找到有人测了:
Mod% in iPhone 13 Pro is (almost always) 16, sometimes it’s 30, but not 100.
From IEEE 1789 (for frequencies between 90 Hz and 1250 Hz):
Mod% < 0.08x(flicker frequency) for Low-Risk Level
and
Mod% < 0.0333x(flicker frequency) for NOEL (no observable effect level)
For 480 Hz we have:
Mod% should be < 38.4 for low-risk and
Mod% should be < 15.984 for NOEL
.
