Outdoor Bus Advertising Display — High-Brightness, IP66-Rated, 24/7 Transit Signage for Any Climate
2500–5000 nits sunlight-readable, IP66 weather-sealed, wide-temperature operation from −40°C to +65°C, and a cloud CMS with remote health monitoring. Built for bus shelters, rolling stock interiors, and fleet exteriors — trusted by DOOH operators, transit authorities, and system integrators who answer tenders.
Four Reasons Transit Projects Fail — and How This Display Answers Each One
Every specification below exists to survive the questions your tender committee, your O&M team, and your media client will ask. No marketing gloss — just engineering decisions you can put in a spec sheet.
Sunlight Readable
Adaptive brightness from 2,500 to 5,000 nits with automatic dimming at night — readable at noon in Dubai, without light pollution after dark.
All-Weather Proof
IP66 sealed chassis, anti-glare tempered glass, optional anti-vandal film, and industrial-grade wide-temperature components rated for sand, salt, frost, and humidity.
Remote Controllable
Cloud CMS with batch scheduling, device health dashboards, and instant failure alerts — one operator runs a national fleet, not a truck roll.
True 24/7 Duty
Industrial panels, sealed power supplies, and smart thermal management keep the screen alive through continuous operation — with a 48-hour aging test before every shipment.
One Hardware Platform. Three Climate Builds. You Pick the Region, We Ship the Right Configuration.
Desert sand, tropical humidity, or Nordic frost — the same Qtenboard platform carries three factory configurations. Tell us the deployment site; the correct filters, coatings, and thermal modules go in before the unit leaves the line.
Middle East · Desert
Sandstorm & Solar Build
For open stops on Gulf highways where screens bake at +65°C and sand is a moving abrasive.
5000 nits direct-sunIP66 sand / dust tightSandstorm filterUV coatingVapor chamber cooling
Southeast Asia · Tropical
Monsoon & Coastal Build
For equatorial fleets and coastal corridors where humidity, salt air, and sudden downpours kill generic screens.
4000–5000 nitsIP66 + salt sprayAnti-corrosion chassisConformal PCB coatingDehumidifier
Nordic · Arctic / Cold
Deep-Freeze Build
For Nordic winters where condensation freezes on glass and cold starts kill under-spec power supplies.
2500–3000 nits anti-glareAuto glass heatingAnti-condensation sensorInsulated enclosure−40°C rated heaterStop Paying for Ads Nobody Can Read at Noon
A 1,500-nit display under direct desert sun is a gray rectangle with an invoice attached. The Qtenboard outdoor bus advertising display pushes 5,000 nits behind anti-glare AG glass — the combination that keeps content crisp where your revenue is earned.
Same stop, same noon light: a standard 1,500-nit screen washes out while the 5,000-nit Qtenboard unit stays vivid.
How to Pick Brightness for Your Site
- Shaded / glazed stops: 2,500 nits is sufficient — keep the night budget down.
- Open, east-west oriented stops: 3,500 nits covers low-angle sun most of the day.
- Open desert / equatorial stops: specify 5,000 nits — the default for Middle East and high-UV Southeast Asia builds.
- Night operation: the ambient-light sensor auto-dims to a preset curve, cutting power draw and avoiding light-pollution complaints from adjacent buildings.
Not sure which build matches your tender? Send the site photo and orientation in the RFQ form — the engineering desk answers with a brightness and cooling recommendation, not a sales line.

Sealed cooling duct, smart fan array, and an optional heating module — the thermal core behind the +65°C and −40°C ratings.
Every model family is validated in-house: high-pressure water jet, 480-hour salt spray, vibration, and drop testing before the batch is released.
Four Models Cover the Whole Transit Footprint
Shelter, interior, and exterior — one vendor, one CMS, one spare-parts pool. Mix models in a single project and keep the management stack identical.
The OBS series: 43″ shelter screen, 55″ double-sided totem, 21.5″ interior rail screen, and 32″ exterior LED board.
| 型號 | 尺寸 | Orientation | Brightness Level | 面板 | 系統 | Typical Use |
|---|---|---|---|---|---|---|

| OBS-E32 | 32″ | Horizontal | 5,000 (opt.) | 1080p | Linux / Android | Bus exterior (side / rear) |
Mounting: floor-standing, wall-mount, or cantilever arm. Front-serviceable design with quick-release locks — media change and service happen from the front, no enclosure dismantling. I/O: HDMI / DP / LVDS, USB 2.0 / 3.0, RJ45, optional 4G / 5G module, RS485 for sensors.
Solution Architecture — What You Actually Manage After Sign-Off
You are not buying a screen. You are buying a network with a single point of control. Here is the stack, layer by layer, and where your existing systems plug in.
Terminal Layer
Outdoor high-brightness screens (shelter / interior / exterior), mounting brackets, and protective accessories — IP-rated, vibration-tested for rolling stock.
Platform Layer
Cloud CMS with multi-tenant access, role-based permissions, audit trails, media library, dynamic scheduling, and a fleet health dashboard.
Network Layer
Wired + 4G hybrid networking with edge caching, offline playback, and log backhaul — a dead tunnel does not kill the campaign.
Data Layer
Play logs, online rates, fault alerts, energy consumption, and brightness reports — configurable, with open APIs for third-party billing and traffic systems.
Fleet view: device map, online / offline status, campaign schedule, and the automated brightness curve — all in one dashboard.
Integration That Won’t Box You In
- Use the Qtenboard cloud CMS out of the box, or point the terminals at your existing CMS via open API.
- White-label the CMS with your own domain and logo for channel and project business.
- Push real-time bus arrival data, weather, and public announcements beside ad slots on the same screen.
- Content best practice for transit: 6–15s primary spots, 15–30s informational blocks, core message inside 3 seconds, large type, high contrast.

FAQ — What Buyers Ask Before They Issue the PO
What brightness do I need for an open bus stop vs. a shaded one?
For open stops facing direct sun, specify the 5,000-nit build (Middle East / high-UV Southeast Asia) or 3,500 nits for moderate climates. Shaded or glazed shelters run comfortably at 2,500 nits. The ambient-light sensor auto-dims at night on every build, so higher daytime brightness does not mean higher night power draw. Refer to the regional variants table above — if the site photo is attached to your RFQ, the engineering desk will confirm the exact figure before you order.
What is the real difference between IP65 and IP66? Do I need IK10?
IP65 protects against low-pressure water jets; IP66 adds protection against powerful high-pressure jets and is the practical baseline for sand-blasted desert stops and monsoon downpours. Both stop dust. IK10 is impact resistance — specify it for unstaffed ground-level stops where vandalism is a real risk; use the IK rating to justify your housing specification in the tender rather than leaving it open.
How does the unit handle +65°C heat or −40°C cold? Do you provide de-rating curves?
Yes. Thermal behavior is documented, not guessed:
- Desert build: vapor-chamber or high-efficiency A/C cooling holds panel temperature within spec at +65°C ambient; sand filters protect airflow.
- Nordic build: glass heating prevents frost and condensation; insulated enclosure and −40°C-rated heater support cold start.
- De-rating curves for brightness vs. ambient temperature are supplied with the engineering file pack, so your O&M team can plan content brightness by season.
Which CMS platforms are supported? Can I integrate with my existing platform?
Terminals ship with the Qtenboard cloud CMS — multi-tenant, white-label capable — or can be pointed at your existing CMS through open APIs. For operators already running a DOOH ad-serving stack, we integrate the player with your scheduling and billing system so the hardware slots into the contract you already have, instead of replacing it.
What are the installation requirements? Is front maintenance supported?
Installation needs a pre-cast pad or steel base and a single cable conduit entry for power and network; the 4G module removes trenching for retrofit stops. Every unit is front-serviceable with quick-release locks — media, filters, and modules are swapped from the front without dismantling the shelter. Full foundation and anchoring drawings ship with the quotation.
What certifications and test reports can you provide for tenders (SASO, IMDA, and others)?
CE, FCC, RoHS, IK10, and IP66 come standard; UL, UKCA, SASO, and IMDA are arranged per target market before mass production. Each quotation includes verifiable certificate numbers and independent test reports (IEC 60529 / IEC 62262), plus the 48-hour aging and salt-spray records for the batch. If your tender lists a certification we have not named, raise it in the RFQ — compliance scope is confirmed in writing before you commit.
