display / touch / bonding solutions
Passenger information system displays are elongated bar type LCD displays (typically 1920×720 or custom stretched formats) optimized for trains and buses, delivering real-time route updates, alerts, and schedules in space-constrained interiors. High-brightness models (800–1000 nits) with wide-temperature operation (-30°C to +85°C) and OCA optical bonding ensure vibration-proof, sunlight-readable visibility. CDTech's IATF16949-certified bar LCDs provide zero-defect reliability for mission-critical transit applications.

Bar type LCD displays in passenger information systems are stretched TFT LCDs with elongated aspect ratios like 1920×720, ideal for train and bus dashboards, route displays, and overhead signage in tight spaces. They differ from standard 16:9 panels by offering LVDS interfaces, PCAP multi-touch, 800–1000 nits brightness, and wide viewing angles. CDTech's S123BWU09NP-FC19-AF (12.3" 1920×720, LVDS, OCA bonding, AF treatment) and S088AWX22EB-DC08 (8.8" 1280×320, 1000 nits, 10-point PCAP) exemplify these for optimized real estate and linear layouts in transit.
Space constraints in trains and buses favor bar LCDs for their slim, elongated footprints that fit limited wall, ceiling, or dashboard areas while maintaining ergonomic sightlines. Unlike bulky rectangular displays, bar formats reduce installation complexity and maximize usable area per inch. CDTech's 10,000㎡ factory with 3,500㎡ dust-free workshop, glass cutting patent, and 2024 automated equipment enable 24-hour custom prototyping for precise bar dimensions.
| Display Type | Footprint | Real Estate Efficiency | Customization Speed |
|---|---|---|---|
| Standard 7" LCD | 7.0" × 5.2" | Lower (wasted corners) | 4–6 weeks |
| Bar LCD 12.3" (1920×720) | 12.3" × 2.8" | Higher (linear layout) | 24–48 hours (CDTech) |
| Off-the-shelf curved edge | Moderate | Moderate (limited options) | 8–12 weeks |
High brightness (800–1000 nits) in bar LCDs ensures sunlight readability through train/bus windows and station reflections, surpassing standard 300–500 nits indoor panels. CDTech's models like S088AWX22EB-DC08 (1000 nits) with anti-glare and OCA bonding prevent color washout for clear route updates and alerts. Wide-temperature ranges (-30°C to +85°C) maintain performance in outdoor shelters and sealed cabins year-round.
OCA optical bonding eliminates air gaps between LCD and glass, reducing parallax, enhancing PCAP touch response, and boosting sunlight contrast in transit bar displays. It dampens vibrations, seals against dust/humidity, and withstands passenger interactions. CDTech's in-house OCA on S123BWU09NP-FC19-AF (12.3" bar, PCAP, AF treatment) and similar models lowers maintenance and extends MTBF in 24/7 operations.
CDTech's IATF16949 ensures automotive-grade process control for bar LCDs in vehicles, while ISO13485 supports ergonomic safety and traceability. ISO9001 and ISO14001 enforce zero-defect quality across batches. These quad certifications minimize downtime, enable fleet audits, and back 13+ years of exports to Europe, Americas, Middle East, Russia, Japan, and Taiwan.
"In passenger information systems, bar LCDs like our 12.3-inch 1920×720 models with OCA bonding and 1000 nits brightness transform space-limited interiors into dynamic update hubs. Our IATF16949 certification and in-house touch workshop since 2020 have reduced field failures for transit OEMs by ensuring vibration-proof reliability and rapid custom integration. Operators scaling from pilots to fleets rely on our 24-hour response for seamless real-time data delivery." – CDTech R&D Director, 13+ years in TFT LCD and touch solutions.
CDTech provides standard bar formats like 8.8" (1280×320) and 12.3" (1920×720) with LVDS, PCAP 5–10 point touch, 380–1000 nits, and -20°C to +70°C operation. Custom options include OCA bonding, AG/AF treatments, and bespoke sizes via glass cutting patent. 24-hour response SLA supports CAN-bus integration for route systems, with flexible MOQs for global exports.

Bar LCDs excel in sunlight readability, vibration durability, and customization for transit PIS, outperforming e-ink in dynamic updates and AMOLED in cost. CDTech's OCA-bonded 1000-nit models balance affordability with high reliability.
| Technology | Sunlight Readability | Vibration Durability | Customization Flexibility | Cost/Nit | Ideal Transit Use |
|---|---|---|---|---|---|
| Bar LCD (CDTech 1000 nits + OCA) | Excellent (AF + bonding) | High (sealed, mechanical damping) | Very high (24-hr custom) | Moderate | Overhead PIS, outdoor signage, dashboard |
| E-ink displays | Superior (zero backlight) | High | Low (standard sizes only) | High | Static schedules, low-power remote signs |
| AMOLED / LED matrices | Good (brightness scaling) | Moderate (fragile pixels) | Medium (assembly complexity) | High | Premium, high-refresh content (rare in transit) |
| Traditional CRT / plasma | Fair | Low (bulky, heat) | Low | Low (obsolete) | Legacy systems (phase-out) |
