LED display for a corporate lobby
A corporate lobby wall is normally built from fine pitch cabinets serviced from the front, so the wall can sit flat against a finished surface with no rear access corridor behind it.
What the room asks for
Viewing distance is short and the screen runs all day, so the pitch is chosen for how close visitors walk past it, not for the far side of the atrium. Brightness has to sit below the level that washes out the surrounding stone and timber.
Layout around fixed structures
Lift cores, columns and reception desks decide the wall outline. Cabinets are cut around those edges, so the wall is drawn from the elevation rather than from a square-metre figure.
Service without closing the lobby
A module is removed from the front with the wall still in place. That keeps the lobby open during a service visit and keeps a rear corridor out of the building plan.
What decides the specification in a lobby
A lobby wall is decided by two numbers the room already has — the 2–4 m passing distance and the light on the stone beside it — and then by two edges: where the joinery stops and how a module comes out.
- Distance sets the pitch
- Visitors cross the wall at 2–4 m and stop closer at reception. Fortis P1.5–P2.6 covers that band; moving to P0.9 adds pixels that cannot be resolved at that distance and adds cost per square metre with nothing visible to show for it.
- Ambient light sets the brightness
- Lobby lighting runs around 300–500 lux. At 600–800 cd/m² the wall holds white text and brand colour without spilling light onto polished stone; pushed higher it becomes the brightest object in the room and flattens the finishes around it.
- The elevation sets the cabinet
- Lift cores, columns and reception desks cut the outline. One 250 × 250 mm module in 1000, 750 and 500 mm wide cabinets is drawn from the elevation, so the wall ends where the joinery ends rather than at the nearest square metre.
- Service sets the access
- Front access keeps the rear corridor out of the building plan, and 33 mm of cabinet depth lets the wall sit on the finished surface rather than in front of it.
| Room condition | What it rules in | What it rules out |
|---|---|---|
| Glazed lobby, 300–500 lux, visitors pass at 2–4 m | P1.5–P2.6 · 600–800 cd/m² · front access | P0.9 spend nobody can resolve, and a rear corridor |
| Wall stops at the lift core — 7.4 m of elevation | Fortis cabinets cut in 250 mm steps, 33 mm deep | A square-metre quote that ignores the elevation |
| Screen on 12 hours a day behind reception | 3,840 Hz, module swapped from the front in place | Rear-service cabinets and floor access |
Boundary. We do not build the joinery, the ceiling pocket or the wall substrate the screen sits on.
What pixel pitch for a 4 m viewing distance?
P1.5–P2.6 covers 2–4 m; below P1.5 the pixels cannot be resolved at that distance.
Do I need rear access for a lobby wall?
No. Front access keeps the rear corridor out of the building plan.
