09 / Buyer FAQ
DOOH LED technical questions.
Practical questions covering brightness, pitch, weather,
power, maintenance and long-term outdoor operation.
01 Is 5,500 cd/m² enough for an outdoor LED billboard?
It can be appropriate for many outdoor installations, but there is
no universal brightness number. Check screen orientation, direct-sun
exposure, ambient light, viewing distance and local nighttime limits.
AQ Series provides 5,000–5,500 cd/m² depending on model; higher-output
RK Pro provides 7,000 cd/m² for projects that require more luminance headroom.
02 What pixel pitch should be used for a roadside LED billboard?
Start with the nearest useful viewing distance, traffic speed,
screen size and content detail. Larger pitches such as P6.67 or P10
are commonly considered for longer-distance media, while smaller
outdoor pitches can support closer viewing and higher image detail.
Confirm the final native resolution before ordering.
03 Does IP65 mean an outdoor LED display is fully weatherproof?
No. IP65 describes tested ingress protection at the rated enclosure
level, but the completed installation also depends on cable glands,
connectors, drainage, ventilation, rear exposure, mounting orientation
and installation quality. Coastal or highly corrosive sites need
additional material and coating review.
04 Is front or rear maintenance better for a DOOH LED screen?
Neither is universally better. Front service is useful for wall-mounted
displays with little rear clearance. Rear service can be efficient
where a safe technical space exists behind the display. Confirm removal
paths for modules, power supplies, receiving cards and fasteners before
the supporting structure is finalized.
05 How should power consumption be calculated for a large DOOH screen?
Use maximum W/m² to size connected electrical capacity and protection,
then estimate annual energy from screen area, realistic average power,
brightness schedule and operating hours. Do not use average power alone
for circuit sizing, and do not use maximum power alone as an annual
energy estimate.
06 What should be monitored remotely on a DOOH LED network?
Depending on the configured control platform, useful functions can
include program publishing, screen/device status, fault alerts,
brightness scheduling and configuration backup. Remote monitoring
complements — but does not replace — safe on-site maintenance and
documented recovery procedures.
