Quote / sample build
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.
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.
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.
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.
PID applications across the station and the carriage
Every point on the passenger journey needs a different display.
In-Station
1 · Platform Departure Board
Mounted on the platform edge or under the canopy. A passenger has three seconds to scan, find the train, and pick a platform.
43"–55" standard · 28"–37" stretch bar · 1,000–5,000 nits
2 · Ticket Vending Machine
Handles 4,000+ transactions a day with wet hands or gloved fingers. Touch must register accurately in both.
19"–27" PCAP touch · 500–3,000 nits · Glove-mode firmware
3 · Wayfinding Terminal
Longer sessions, map pinch-to-zoom, multi-language. The display must handle smooth gestures and meet accessibility contrast.
32"–43" PCAP touch · 1,500–2,500 nits · Slim 25–35mm depth
4 · Concourse Information Wall
High on a departure-hall wall, running departure times, service alerts, and emergency notices in a multi-zone layout.
65"–86" 4K UHD · 2,500–3,000 nits · Metal chassis heat sink
5 · Platform Edge Strip
The narrowest display in the station — a slot along the platform edge, 150–200 mm tall max. Stretch-bar is the only answer.
28"–49" stretch bar · 3840×360 to 3840×540 · ~90mm tall
6 · Station Entrance Totem
The street-facing identifier — faces 100,000+ lux of midday sun, monsoon rain, and vandalism. The harshest zone.
43"–65" · 2,500–5,000 nits · IP65/66 · IK10 · Solar-resilient
Onboard / In-Carriage
7 · Ceiling Dynamic Route Line
Mounted centre-ceiling, showing the next three stops as a left-to-right line. Curved carriage roofs mean a rectangular monitor won't fit.
Stretch bar · contour-cut · 700–1,500 nits · Rolling-stock vibration rated
8 · Door-Side / Side Panel
Above the door or along the sidewall — a narrow curved surface showing next-stop, transfer, and emergency messaging.
Narrow stretch bar · slim bezel · 700–1,500 nits · Anti-glare

Talk to an ExpertThree environmental zones
A display engineered for an indoor mezzanine will blacken, fog, or shake loose at a street-level entrance. Never mix zones.
Zone A · Fully Indoor
Underground platforms, mezzanines, ticket halls
200–500 lux · 1,000–1,500 nits · Standard IPS/ADS
Threat: Dust, humidity, vibration, 24/7 uptime
Zone B · Semi-Outdoor
Covered entrances, vented concourses, skybridges
Variable sun · 1,500–2,500 nits · IPS + anti-glare
Threat: Glare, temperature swing, condensation
Zone C · Fully Outdoor
Entrance totems, open-air platform ends
100,000+ lux · 2,500–5,000 nits · Solar-resilient ≥110°C
Threat: 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. Solar-resilient panels raise the clearing point to ≥110°C.
Why a panel fogs
An unbonded display condenses moisture between the LCD and cover glass within weeks. Optical bonding removes the air gap entirely and cuts reflection by ~80%.
Why connectors fail
A friction-only HDMI backs out half a millimetre within ~20,000 train cycles. Screw-lock connectors, through-hole PCBs, and thread-locked fasteners are the minimum.
Engineering that keeps the network online
The capabilities that differentiate a PID-grade display from a consumer monitor placed in a station.
High Brightness, Auto-Dimming
500–5,000 nits with ambient light sensors — readable in direct sun, dimmed overnight to extend backlight life.
Solar-Resilient Panels
Higher liquid-crystal clearing point (≥110°C) to prevent blackening defects under sustained solar loading.
IP65 / IP66 Sealing
Fully sealed enclosures with EPDM gaskets and industrial breather vents to prevent internal condensation.
In-House Optical Bonding
OCA sheet or OCR liquid resin — eliminates the air gap that causes fogging and cuts reflection by ~80%.
-20°C to 70°C Operation
Industrial-grade stability across all global climates, with optional PTC heating for cold-start below 0°C.
PCAP Touch, Hardened
Glove mode, wet-hand rejection, palm and water-drop rejection — survives public-transit duty cycles.
Vibration-Secured Assembly
Screw-lock connectors, through-hole PCBs, thread-locked fasteners, and EPDM gaskets — standard on every unit.
Up to 50,000-h Backlight
Industrial-grade WLED backlighting rated for 24/7 continuous operation with auto-dimming.
Network Integration
LVDS, eDP, HDMI, DP, dual RJ45, RS-232 — standard interfaces that integrate with Siemens, Alstom, and Thales PIS.
Display Solutions for Every Deployment

Open Frame Monitor
7"–65" PCAP touch modules for TVMs, wayfinding kiosks, and custom enclosures
Outdoor Waterproof Display
IP65/IP66 sealed signage for entrance totems and street-level installations

Frequently Asked Questions
It depends on location:
- • Underground (Zone A): 1,000–1,500 nits
- • Semi-Outdoor (Zone B): 1,500–2,500 nits
- • Fully Outdoor (Zone C): 2,500–5,000 nits
- • All high-brightness units must include ambient light sensors.
Standard 16:9 panels do not fit platform-screen-door headers, ceiling route lines, or carriage interiors. Stretch-bar panels are cut and re-driven from full Tier-1 glass — not cropped 16:9 units.
Standard liquid crystal clears at ~70–80°C. Solar loading pushes sun-exposed displays past that point. Solar-resilient panels raise the clearing point to ≥110°C.
