Built for networks,
not for showrooms.

A metro line runs 80 to 200 displays across environments that share nothing but a timetable. We engineer the hardware that keeps all of them readable, online, and serviceable — for the life of the project.

01

Matched to the zone

Brightness, sealing, and panel technology are specified per location — an underground platform board and a street-level entrance totem are not the same product.

02

Form factor that fits

Standard 16:9 won't fit a platform-screen-door header or a carriage ceiling. We cut and re-drive stretch-bar panels from full Tier-1 glass — not cropped 16:9 units.

03

Specified to survive

Screw-lock connectors, thread-locked fasteners, EPDM gaskets, and in-house optical bonding — because the failure mode that returns a display is rarely brightness. It's vibration, fogging, and seal breakdown.

Eight deployment points

PID applications across the station and the carriage

Every point on the passenger journey needs a different display. Below is the hardware configuration we specify for each — sized, brightened, and sealed for the actual location.

In-Station

Six points from the street entrance to the platform edge.

Platform departure board

1 · Platform Departure Board High-visibility

Mounted on the platform edge or under the canopy. A passenger has three seconds to scan, find the train, and pick a platform — readability is non-negotiable.

Form:
43"–55" standard, or 28"–37" stretch bar underground
Brightness:
2,500–5,000 nits open-air · 1,000–1,500 nits underground
Critical:
Optical bonding + anti-reflective glass; passive chassis cooling
Ticket vending machine display

2 · Ticket Vending Machine Touch · 24/7

A busy TVM handles 4,000+ transactions a day, often with wet hands or gloved fingers. Touch must register accurately in both, and the panel must survive the punishment.

Form:
19"–27" PCAP touch, open frame for custom kiosk housing
Brightness:
2,000–3,000 nits outdoor · 500–1,000 nits concourse
Critical:
Glove-mode & wet-hand firmware; screw-lock USB touch
Wayfinding kiosk display

3 · Wayfinding Terminal Interactive

For passengers who are lost, not commuting: longer sessions, map pinch-to-zoom, multi-language. The display must handle smooth gestures and meet accessibility contrast at arm's length.

Form:
32"–43" PCAP touch, slim open frame (25–35 mm depth)
Brightness:
1,500 nits skylit concourse · 2,500 nits sun-facing entrance
Critical:
Low-profile depth supports wheelchair-height mounting
Concourse information wall

4 · Concourse Information Wall Large format

High on a departure-hall wall or ceiling-suspended, running departure times, service alerts, advertising, and emergency notices in a multi-zone layout. A brightness dip is immediately visible.

Form:
65"–86", non-touch, 4K UHD
Brightness:
2,500–3,000 nits with uniform luminance
Critical:
Metal chassis as heat sink; 3–5 yr model availability
Platform edge stretch bar

5 · Platform Edge Strip Stretch bar

The narrowest display in the station — a slot along the platform edge or under the canopy, 150–200 mm tall max. A 16:9 panel simply does not fit. Stretch-bar is the only honest answer.

Form:
28"–49" stretch bar, 3840×360 to 3840×540, only ~90 mm tall
Brightness:
1,000–1,500 nits covered · 2,500–4,000 nits open-air
Critical:
Stiffening ribs + mounting points every 200–300 mm
Station entrance totem

6 · Station Entrance Totem Full outdoor

The street-facing identifier — first and last screen a passenger sees. It faces 100,000+ lux of midday sun, monsoon rain, and vandalism. This is the harshest zone in the network.

Form:
43"–65" + stretch bar header, IK10 tempered glass
Brightness:
2,500–5,000 nits, solar-resilient panels
Critical:
IP65/66, ambient light sensor, breather vents

Onboard / In-Carriage

Curved interiors and narrow mounting leave no room for standard panels.

Onboard ceiling route line display

7 · Ceiling Dynamic Route Line Stretch bar

Mounted centre-ceiling, showing the next three stops as a left-to-right line the passenger reads while standing. Curved carriage roofs mean a rectangular monitor won't fit the cutout.

Form:
Stretch bar, contour-cut to carriage curvature
Brightness:
700–1,500 nits for controlled interior lighting
Critical:
Rolling-stock vibration; locking connectors throughout
Door-side carriage display

8 · Door-Side / Side Panel Stretch bar

Above the door or along the sidewall — a narrow curved surface that shows next-stop, transfer, and emergency messaging. The footprint is too thin for anything but a stretch panel.

Form:
Narrow stretch bar, slim bezel, low-depth chassis
Brightness:
700–1,500 nits, anti-glare for interior reflection
Critical:
Door-cycling shock; continuous 24/7 backlight life

Specify by environment, not by catalog

Three environmental zones — one rule: never mix them up

A display engineered for an indoor mezzanine will blacken, fog, or shake loose within a single summer at a street-level entrance. Mixing zones is the most common — and most expensive — error in a PID project.

Zone Location Ambient Light Brightness Spec Panel Technology Primary Threat
A · Fully Indoor Underground platforms, mezzanines, ticket halls 200–500 lux fluorescent 1,000–1,500 nits Standard IPS / ADS Dust, humidity, vibration, 24/7 uptime
B · Semi-Outdoor Covered entrances, vented concourses, skybridges Variable, sun-exposed part of day 1,500–2,500 nits IPS + anti-glare coating Glare, temperature swing, condensation
C · Fully Outdoor Entrance totems, open-air platform ends 100,000+ lux direct sun 2,500–5,000 nits Solar-resilient (≥110°C clearing point) Solar blackening, rain, vandalism

Why a panel blackens

Standard liquid crystal clears at ~70–80°C. Solar loading pushes a sun-exposed totem past that point, causing irreversible blackening — exactly when brightness is needed most. Solar-resilient panels raise the clearing point to ≥110°C.

Why a panel fogs

An unbonded display on a Zone B or C location condenses moisture between the LCD and cover glass within weeks — a haze layer no external wipe can reach. Optical bonding removes the air gap entirely and cuts reflection by ~80%.

Why connectors fail

A friction-only HDMI or USB backs out half a millimetre within ~20,000 train cycles — enough to lose signal intermittently. Screw-lock connectors, through-hole PCBs, and thread-locked fasteners are the minimum, not an upgrade.

Engineering that keeps the network online

The capabilities below are what differentiate a PID-grade display from a consumer monitor placed in a station. Each one maps to a specific field-failure mode we have engineered out.

High Brightness, Auto-Dimming

500–5,000 nits with ambient light sensors — readable in direct sun, dimmed overnight to extend backlight life and cut energy cost across a 200-display network.

Solar-Resilient Panels

Formulated with a higher liquid-crystal clearing point (≥110°C) to prevent blackening defects under sustained solar loading — the difference between surviving a desert summer and an August RMA.

IP65 / IP66 Sealing

Fully sealed enclosures against heavy rain, dust, and salt spray — with EPDM gaskets and industrial breather vents to equalize pressure and prevent internal condensation.

In-House Optical Bonding

OCA sheet or OCR liquid resin, performed inside our ISO 9001 facility — eliminates the air gap that causes fogging and cuts reflection by ~80% without adding a single nit of backlight power.

-20°C to 70°C Operation

Industrial-grade stability across all global climates, from Arctic cold to desert heat — with optional PTC heating for reliable cold-start below 0°C.

PCAP Touch, Hardened

Glove mode, wet-hand rejection, palm and water-drop rejection — the only touch technology that survives public-transit duty cycles on ticket machines and wayfinding kiosks.

Vibration-Secured Assembly

Screw-lock HDMI/USB/DC, through-hole PCB connectors, thread-locked chassis fasteners, and EPDM dampening gaskets — standard on every transit-qualified unit.

50,000

Up to 50,000-h Backlight

Industrial-grade WLED backlighting rated for 24/7 continuous operation — minimal brightness drift over lifespan, with auto-dimming to push toward rated life.

Network Integration

LVDS, eDP, HDMI, DP, dual RJ45 with loop-through, RS-232, and external ambient-sensor ports — standard interfaces that integrate with existing PIS from Siemens, Alstom, or Thales without adapters.

Pre-Installed Operating Systems

A PID display is a node on a station-wide network, not a standalone device. Standard LVDS, eDP, HDMI, and Ethernet interfaces support plug-and-play integration with major PIS platforms — including those from Siemens, Alstom, and Thales — without custom adapters. Dual RJ45 with HDMI loop-through allows daisy-chain across a platform; RS-232 supports centralized remote management.

We can pre-install your preferred OS at the factory — Windows 7/10/11 IoT, Linux (Ubuntu / Debian), or Android 11 through 14 — with full BSP and driver support, so the unit runs the moment it arrives.

Frequently Asked Questions

The questions integrators and engineering teams ask before signing off on a transit deployment.

It depends entirely on location. Underground platforms and concourses need 1,000–1,500 nits. Semi-outdoor covered entrances need 1,500–2,500 nits. Fully exposed street-level entrances need 2,500–5,000 nits with solar-resilient panels.

  • • Underground (Zone A): 1,000–1,500 nits, standard IPS/ADS panels, 200–500 lux ambient.
  • • Semi-Outdoor (Zone B): 1,500–2,500 nits, IPS + anti-glare coating, variable sun exposure.
  • • Fully Outdoor (Zone C): 2,500–5,000 nits, solar-resilient panels (≥110°C clearing point), 100,000+ lux direct sun.
  • • All high-brightness units must include ambient light sensors for 24/7 dimming to prevent light pollution and protect driver sightlines.

Standard 16:9 panels do not fit the physical constraints of a transit environment — platform-screen-door headers, ceiling route lines, and carriage interiors are narrow horizontal slots.

  • • Stretch-bar panels with custom ratios (1920×360, 3840×360, 1920×720, 2880×480) are cut and re-driven from full Tier-1 glass.
  • • They inherit the same brightness, lifespan, and color uniformity as the standard panel they were cut from.
  • • They are not cropped 16:9 units — they are purpose-built for the transit form factor.

Standard liquid crystal clears at roughly 70–80°C. Direct solar loading pushes a sun-exposed entrance totem past that surface temperature, causing irreversible blackening defects.

  • • Solar-resilient panels raise the liquid-crystal clearing point to ≥110°C.
  • • Paired with passive chassis cooling or heat-pipe dissipation.
  • • This is mandatory for any PID display exposed to direct solar radiation.
  • • IP65/IP66 is the minimum for front-side protection against high-pressure cleaning and monsoon rain.
  • • IK10 (20-joule impact) is mandatory for any ground-level or within-reach installation to withstand vandalism.
  • • All sealed IP-rated enclosures must include industrial-grade breather vents to equalize pressure and prevent internal condensation.

Every passing train sends a low-frequency shockwave through the station structure. Over months, friction-only connectors walk loose, solder joints crack, and chassis fasteners back out.

  • • Screw-lock HDMI/USB/DC connectors — never friction-only.
  • • Through-hole board mounting for all external connectors.
  • • Thread-locking compound on every chassis fastener.
  • • EPDM vibration-dampening gaskets at the panel-to-enclosure interface.

Yes. Standard LVDS, eDP, HDMI, and Ethernet interfaces support plug-and-play integration with major PIS platforms without custom adapters.

  • • Dual RJ45 with HDMI loop-through enables daisy-chain across a platform.
  • • RS-232 supports centralized remote management across dozens of units.
  • • Custom firmware available for proprietary protocols where required.
  • • MOQ: One unit for samples.
  • • Custom samples: Built, tested, and shipped within 10 working days.
  • • Technical response: Within 8 hours of enquiry.
  • • Volume production: 15–25 working day lead time with batch-to-batch traceability.
