[ GLOSSARY DEFINITION ]
Display
PWM Dimming
Pulse-width modulation used to dim OLEDs; low frequency can cause eye strain for sensitive users.
Also known as:
PWM
Flicker
Full Definition & Technical Explanation
PWM dimming flickers an OLED's brightness at a frequency (e.g., 240 Hz, 1920 Hz). High PWM is comfortable; low PWM may cause headaches and eye fatigue, especially at low brightness. DC-like or high-frequency PWM is preferred.
See PWM: 240 Hz vs 1920 Hz / Not detected in display specs. Panels that report "Not detected" typically use DC dimming, which is easiest on the eyes.
