| Brightness and sunlight | For outdoor stadium displays exposed to daylight, a rated maximum brightness in the approximate range of 5,000–8,000 cd/m² (nits) is commonly considered. The right level depends on direct-sun exposure, screen orientation, and viewing conditions. | Request measured brightness data, confirm the measurement method and operating mode, and check that automatic brightness control can reduce output after dark. |
| Weather and water protection | For exposed outdoor cabinets, IP65-rated front protection is a common specification. Rear-side protection should match the installation location; a sheltered rear may have different requirements from an area exposed to rain or washdown. | Check the IP rating for the complete cabinet and its connectors, not just individual components. Confirm drainage, seals, cable entries, and the maintenance procedure after water exposure. |
| Wind load and structural support | Wind pressure depends on the site, screen height, geometry, exposure, and applicable building regulations. There is no single wind-load value suitable for every stadium installation. | Have a qualified structural engineer check the supporting structure, fixings, screen dead load, wind actions, vibration, and maintenance access against the project location’s applicable codes. |
| Pixel pitch and viewing distance | A finer pixel pitch can improve detail for closer viewers but generally raises cost and may increase power demand. Larger pitches can be suitable for screens viewed from farther away; the best choice depends on audience positions and content. | Assess the nearest and farthest viewing locations, screen dimensions, camera use, and typical content. Review a sample image or mock-up from representative seating positions. |
| Refresh rate and camera performance | A refresh rate of 3,840 Hz or higher is often specified for broadcast-oriented LED displays, but camera results also depend on shutter speed, scan method, processing, and brightness settings. | Test the display with the cameras and shutter settings expected at the venue. Check for flicker, scan lines, color shifts, and image artifacts at several brightness levels. |
| Temperature and ventilation | Operating temperature limits vary by product and installation. Direct sunlight, enclosed cabinets, and limited airflow can raise internal temperatures beyond the surrounding air temperature. | Confirm the specified operating range, thermal management method, ventilation clearances, and any derating requirements. Consider local summer and winter conditions. |
| Power and energy use | Power consumption changes with brightness, displayed content, refresh settings, and operating conditions. Maximum and typical consumption are different figures and should not be treated as interchangeable. | Request both maximum and typical power data, then size circuits and distribution equipment with the project’s electrical engineer. Include monitoring, grounding, and surge protection in the design. |
| Maintenance and service access | Front or rear service access should suit the screen’s mounting location. Outdoor installations also need practical access for inspection, cleaning, and replacement of modules or power components. | Review access routes, lifting points, fall protection, spare-parts availability, and the proposed maintenance plan before finalizing the cabinet layout. |
| Documentation and acceptance testing | A complete project specification should cover display performance, environmental protection, structural interfaces, electrical requirements, and commissioning criteria. | Agree on drawings, test reports, installation tolerances, image-quality checks, training, warranty terms, and handover documents before procurement. |
