| Cost per sqm | Higher (finer pitch) | Lower (coarser pitch) |
| Maintenance access | Rear access typical | Front or rear, weather-sealed |
Brightness Is the Critical Factor
Outdoor screens need to compete with direct sunlight, which can reach 100,000 lux on a clear day. To remain legible and visually impactful in those conditions, outdoor LED panels are rated at 5,000 nits minimum — with premium outdoor panels reaching 10,000 nits or more.
An indoor screen running at 1,000 nits would be completely washed out in direct sunlight — essentially invisible. Conversely, using an outdoor-rated screen indoors creates a different problem: the extreme brightness causes eye fatigue and is wasteful from an energy standpoint. A well-designed indoor environment typically calls for 800–1,500 nits.
Modern outdoor displays include automatic brightness sensors that adjust output based on ambient light conditions — maximising visibility in peak sunlight and reducing power consumption at night.
Weatherproofing for the Australian Climate
Outdoor LED panels are sealed to IP65 or IP68 ratings — protected against dust ingress and water jets from any direction. But Australia adds several layers of complexity beyond simply keeping rain out.
UV exposure
Australia has some of the highest UV radiation levels in the world. Outdoor panels must use UV-stabilised materials to prevent degradation of housings, cables, and optical elements.
Coastal salt air
Screens within a few kilometres of the coast are exposed to salt-laden air that accelerates corrosion. Marine-grade sealing and corrosion-resistant hardware are essential.
Temperature extremes
From −10°C in inland winters to +50°C on exposed metal surfaces in summer, Australian outdoor displays need active thermal management and a wide operating temperature range.
Storm and hail
Queensland and other storm-prone regions expose displays to high-velocity debris. Robust front glass and structural engineering matter.
Why Outdoor Screens Use Coarser Pixel Pitch
Outdoor billboards and large-format signage are typically viewed from distances of 10–100+ metres. At those distances, a P8mm or P10mm pixel pitch looks perfectly sharp to the human eye — there's simply no need for the fine resolution of a P1.5mm indoor display.
Using a fine-pitch panel outdoors would dramatically increase cost (more LEDs per square metre) while providing no perceptible benefit. Coarser pitches also allow more space between LEDs for thermal management and structural integrity — both important for outdoor environments.
Semi-Outdoor
Under awnings, behind glass, or in open-air shopping centres?
Semi-outdoor environments — covered but not fully enclosed spaces like undercover car parks, open-air malls, transit stations, or screens visible through glass facades — require a hybrid approach. Typically this means high-brightness indoor panels (2,000–3,500 nits) with appropriate moisture protection, or weather-rated panels with moderate brightness. We assess the specific conditions and recommend the right specification.
Maintenance Access
Indoor installations often allow rear service access — a maintenance corridor or accessible void behind the screen. This makes servicing straightforward.
Outdoor displays are almost always front-serviceable by design — removing individual tiles from the front face without scaffolding or major disruption. Premium outdoor panels like the Leyard LA Series support tool-free front access, which dramatically reduces the cost and downtime of any maintenance event.
