[ GLOSSARY DEFINITION ]
Display
local dimming
A technique that dims sections of an LCD backlight independently to deepen blacks and raise contrast, common in HDR displays.
Full Definition & Technical Explanation
Local dimming adjusts the brightness of separate regions of a display's backlight so dark parts of the image can be dimmed while bright areas stay lit. On LCD panels this dramatically improves contrast and HDR impact compared with a single always-on backlight.
It comes in edge-lit and full-array forms; FALD uses many dimming zones behind the panel. Poorly tuned dimming can cause blooming.
