Metro LCD Passenger
Information Displays

One line, two worlds.

One metro line runs through two worlds — tunnel-dark platforms and sun-lit entrances. We specify the LCD hardware per zone, so every passenger reads arrival, alert and route map clearly, from the carriage ceiling to the platform edge.

The metro contradiction

Two lighting worlds, one timetable.

A metro line packs passenger-facing displays into zones that share nothing but a timetable. Underground platforms fight glare and humidity at 2–3 minute headways; street-level entrances face direct sun and weather; carriages carry vibration, dust and 24/7 duty. At the platform edge, a stretch bar must tell riders exactly where the doors will land.

One display family cannot serve all of it — so we specify per zone, not per brand.

Brightness follows the light

A single line runs from a dark tunnel to a sun-lit entrance — we set brightness and sealing per zone.

dns LCD vs LED legacy

In a metro's mixed lighting, LCD shows route maps, service alerts and video from one uniform panel — legible stepping off a dark platform into daylight. Legacy LED dot-matrix stays readable only for a fixed glyph board already specified; for the day-to-day information a metro carries, LCD is the forward path.

Open interfaces,
no lock-in

No locked software, no forced middleware.

We supply the display hardware and the open interfaces — SDK/API, HDMI, LAN and serial (M12 where specified) — so our panels drop into your existing metro PIS and CMS without a forklift upgrade.

Integrators retrofit our screens into ageing networks alongside any vendor's signage controller; we never lock you to one software stack.

Frequently asked

Everything you need to know about specifying metro display hardware.

01 Can LCD stay readable from a dark tunnel onto a sunny entrance?

Yes. We specify 500–2,500 nits underground and 2,500–5,000 nits at the entrance, with optical bonding that holds contrast across the lighting change.

02 Do your stretch bars align with where doors actually stop?

They're positioned at the platform edge to mark door and next-stop status; we size and mount them to your platform's door-zone layout.

03 Will these retrofit into our older metro cars?

Slim open-frame and <25mm door-header profiles drop into existing casings; M12 and screw-lock connectors are rated for continuous in-service vibration.

04 Can we keep our current PIS software?

Yes. Open SDK/API and standard interfaces let your existing PIS/CMS drive the screens; no locked stack, and we don't supply the scheduling logic.

05 How do we pick brightness for a new station?

By zone, not by line: measure ambient light at the worst hour (platform vs entrance), then match our 500–5,000 nits bands. We'll help map your lux readings to a spec.

06 What certifications apply to onboard vs station units?

Onboard (metro car) follows a rail-grade path, compliance-ready to EN 50155 / EN 45545 / IEC 61373. Station and entrance units are CE / RoHS / FCC certified, ISO 9001 certified, with IP65/IP66.
