Quick answer: PWM dimming controls OLED brightness by pulsing pixels rapidly. Some people notice flicker/eye strain at low brightness. Higher PWM frequency or DC-like dimming modes can help sensitive users.
OLED phone threads obsess over PWM graphs.
This explainer is based on how pwm dimming (phones) is marketed on product pages and buyer guides. Gadget Clash does not lab-test every SKU. Confirm the exact model specs before you buy.
