看到notebookcheck这样讲
吓了一跳
真有这种技术?

PWM flickering only occurs at display brightness levels of 30% and less.
Above this level, automatic DC dimming starts
The display backlight flickers at 227.3 Hz (Likely utilizing PWM) Flickering
detected at a brightness setting of 30 % and below. There should be no
flickering or PWM above this brightness setting.
如果有乡民觉得notebookcheck不可信
可以去借S20 FE来测
一个月前板上看到一种说法:
iPhone12亮度25%以上采DC调光

照notebookcheck的测试
上述说法并不正确
iphone 12只有在最大亮度停止闪烁

Because OLEDs don't have background lighting that you could dimm, the entire
screen has to be turned on and off all the time to achieve a lower
brightness. This causes flickering, which we measured at 226.2 Hz on the
iPhone 12. It only stops at maximum brightness.
相信某些对PWM着迷的乡民会努力去验证notebookcheck的说法
据oneplus创办人的说法
什么类DC调光
那只是厂商的噱头啦
别被骗了
