Understanding Commercial LED Displays: Technology and Construction

At the core of commercial LED display technology are Light Emitting Diodes (LEDs), semiconductor devices that emit light when an electrical current passes through them. Today’s commercial LED displays utilize surface-mounted (SMD) or through-hole LEDs arranged in modular panels to create seamless visual surfaces capable of displaying vibrant images and videos.

Pixel Pitch and Resolution

Pixel pitch — the distance between the center of two adjacent LEDs — is a fundamental parameter shaping image resolution and viewing distance. Commercial LED displays range from fine pitches (~0.9 mm for indoor close-viewing applications) to coarse pitches (10 mm and above, typical for large outdoor billboards). Lower pixel pitches yield higher resolution, necessary for closer viewing environments, whereas coarser pitches suffice where viewing distances are greater.
