LED display
glossary.

Every acronym you'll see on a spec sheet, defined once. Plain English where possible, units and sources where it matters.

Pixel pitch
Distance from one LED's center to the next, in millimeters. Smaller = sharper image, denser pixels per square meter, higher cost. Full guide →
Pixel density
LEDs per square meter. Inversely related to pitch — a 1.5 mm panel has ~444 444 LEDs/m², a 6 mm panel has ~27 778. Drives panel weight, power draw, and cost.
Refresh rate
How many times per second a panel re-paints its image, in Hz. For broadcast and XR, you want ≥3 840 Hz; for cinema-grade XR with high-frame-rate cameras, 7 680 Hz. Distinct from frame rate (your content's fps).
Scan rate
A multiplexing ratio — how many LEDs share one driver pin. 1/8 scan, 1/16 scan, etc. Lower numerator = higher static brightness; higher numerator = lower power but slightly worse off-axis.
Brightness (nit)
Luminance per square meter (cd/m²). Indoor: 600–1 500 nit. Bright lobby: ~2 000. Outdoor: 4 000+. Direct-sun stadium: 5 000+.
HDR-10
High Dynamic Range standard with 10-bit color depth and SMPTE ST 2084 (PQ) tone curve. Requires high peak brightness and a wide color gamut. The de-facto standard for premium video and XR pipelines.
Greyscale (bit depth)
How many distinct levels of brightness per primary color the panel can display. 8-bit = 256 levels, 10-bit = 1 024, 20-bit = 1 048 576. More bits = smoother gradients (no banding) and better headroom for color processing.
Color gamut
The range of colors a panel can produce. sRGB (basic web), Rec.709 (HDTV), DCI-P3 (cinema), Rec.2020 (UHDTV). Pisces Orion XR covers >90% of DCI-P3.
ΔE (Delta E)
Perceptual color difference. ΔE < 1 is invisible to most observers; ΔE < 2 is barely perceptible. Pisces panels ship at ΔE < 0.5 uniformity at white point.
Genlock
Hardware sync between the LED panel and the camera, so the panel's refresh aligns with the camera's shutter. Without it, you get scan lines, banding, or rolling-shutter wobble in shot.
IP rating
Ingress Protection. First digit = solids (dust), second = liquids (water). IP65 = dust-tight + water jets from any direction. IP67 = dust-tight + brief immersion. Outdoor LED needs at least IP65 on the front face.
ACES
Academy Color Encoding System — a master color framework used in cinema and XR pipelines. IDT (input transform) → ACES working space → RRT (reference rendering) → ODT (output transform) for your display.
Modular cabinet
A cabinet (frame + LED modules + processor) that pin-locks to its neighbors with no tools. The base unit of touring rentals — you order, ship, and replace at the cabinet level, not the LED level.
Front- vs rear-serviceable
Where you remove modules from when servicing. Front-serviceable is critical for installs flush against a structural wall; rear-serviceable is fine when you have access behind the wall.
Receive card
The processor inside each cabinet that decodes the video signal, applies calibration data, and drives the LEDs. Critical service item — ours auto-discover replacements without manual addressing.
