[ GLOSSARY DEFINITION ]
Display
DC dimming
Controlling display brightness by varying current rather than rapidly switching the backlight, avoiding flicker.
Full Definition & Technical Explanation
DC dimming adjusts a display's brightness by changing the current to the backlight directly, instead of switching it on and off rapidly. This avoids the flicker that PWM dimming can produce, making it easier on sensitive eyes.
It is often listed as "flicker-free"; see anti-flicker and low blue light.
