LED Screen Technical Glossary
Understand pixel pitch, refresh rate, nit, video processor, receiving card, cabinet and other core LED terms.
Pixel pitch
The distance between pixel centres. A smaller pitch generally means higher pixel density for closer viewing.
Refresh rate
How frequently the display refreshes the image; suitable refresh rate matters for camera capture.
Nit / brightness
A unit used for display luminance. Ambient light and environment affect the required level.
Video processor
A system that scales and maps incoming video to the LED wall’s actual resolution and layout.
