Thanks for the OnePlus 12 review. Dear editorial staff, could you tell us how you test devices for PWM? I am very sensitive to PWM and therefore purchased an additional opple lightmaster device. I tested it on the Oneplus 12 PWM, as well as several other smartphones, laptops and TVs. The frequencies shown by them corresponded to those stated by the manufacturer. So on the Oneplus 12 with ultra anti flicker TURNED ON at brightness from 100% to about 25%, the frequency was 744hz Hz and the ripple coefficient was around 80-95%. At a brightness below 25%, high-frequency dc-dimming was turned on, it was 2200 Hz. The same indicator is stated by the manufacturer. Without the ultra anti flicker function enabled, at brightness from 100 to 25%, the frequency was 123Hz and the ripple coefficient was 50 - 70%. I also tested my Honor 20 pro with ips display. There the frequency was 19220hz and a coefficient of 9.5% at 50% brightness. Additionally, I tested the Samsung Galaxy s24. The frequency was, as indicated by the manufacturer, 480hz.
