faytech’s outdoor displays have proven their reliability in one of the toughest real-world tests. A set of 32-inch IP65 outdoor displays installed in 2014 along Hong Kong’s East Rail line mass transit system are still in operation today, more than 12 years later, with each screen exceeding 80,000 hours of usage.
This long-term success reflects what faytech stands for: reliability, endurance, quality, and performance.


faytech’s Remarkable 12+ Year Outdoor Success Story in Hong Kong
In 2014, faytech partnered to install 32″ IP65 outdoor displays as passenger information display systems (PIDS) across key stations on Hong Kong’s East Rail line. This included Fanling, Tai Po Market, Fo Tan, Sha Tin, Tai Wai, and Kowloon Tong.
These displays have operated for over a decade in Hong Kong’s humid, hot, and variable climate, in a demanding, high-traffic transit environment. Each unit has logged more than 80,000 hours of continuous operation while maintaining stable performance and clear visuals.
To meet strict transit certification requirements, faytech developed a custom solution that:

- Integrated a unique EMI film between the cover glass and display
- Used a customized all-in-one (AIO) cable design to minimize radiation and interference
- Ensured vibration-resistant construction for long-term stability
The result is a durable, low-maintenance display system that continues to deliver reliable passenger information where downtime would be costly and disruptive.

“Seeing these IP65 outdoor displays still running after more than 12 years and over 80,000 hours, while still looking almost like new, makes me incredibly proud of faytech’s quality,” says Arne Weber, Managing Founder of faytech. “Back in 2013, we were under real pressure to master every detail of transit requirements, EMI shielding, and vibration-proof design to ensure we built a truly reliable product. The Hong Kong East Rail installation proves that all of that effort was worth it.”
How Optical Bonding Powers faytech’s Long-Lifetime Outdoor Displays
Back during the installation of this project, we didn’t implement optical bonding yet, however in later installations, Optical Bonding has been used and plays a central role in achieving the perfect use in outdoor and semi-outdoor installations. The process fills the air gap between the LCD panel and the protective cover glass or touch panel with faytech’s patented Clear-Bond silicone adhesive. This creates one solid, unified unit rather than separate layers.
By eliminating the air gap, optical bonding dramatically improves optical performance and structural integrity. faytech handles the entire process in-house within controlled cleanrooms, which ensures precision and consistent quality even for demanding outdoor applications.
Key Benefits That Support 12+ Years of Reliable Operation
faytech’s Optical bonding delivers advantages that directly enable long-term success in harsh environments:
- Strong Sunlight Readability and Clarity: Reduces internal reflections significantly while boosting perceived brightness. This keeps screens visible and sharp even in bright or variable outdoor lighting conditions.
- Enhanced Durability and Impact Resistance: The bonded assembly acts as a shock absorber, providing better resistance to vibration, impacts, and daily wear common in transit and public settings.
- Superior Environmental Protection: No air gap means excellent resistance to humidity, dust, fog, and moisture ingress; critical for Hong Kong’s climate and similar outdoor locations.
- Improved Touch Performance: Smoother, more reliable multi-touch interaction that holds up over years of use.
- Extended Lifetime and Lower Total Costs: Reduced maintenance needs and proven multi-year (and decade-plus) performance translate into strong ROI for operators.
faytech’s custom engineering like the EMI film solution, rugged design, explain why the Hong Kong monitors continue running strongly after more than 80,000 hours.
Engineering for Transit: EMI, Vibration, and IP Protection
faytech’s outdoor displays incorporate a range of engineering features tailored to transit and other demanding environments:
- EMI Shielding: Custom EMI film between cover glass and display, plus a tailored cable concept, keeps emissions within transit standards. This prevents interference with nearby systems.
- Vibration-Proof Design: Mechanically stable construction and mounting protect against continuous vibration in rail environments.
- IP65 Protection: Robust enclosures shield the system from dust and water jets, ensuring reliability in exposed or semi-outdoor installations.

This integrated approach is what enables the Hong Kong monitors to remain in daily service for more than a decade.


Why Long-Lifetime Outdoor Displays Matter
As smart cities, transportation hubs, EV infrastructure, and outdoor retail expand their digital signage and HMI networks, standard consumer-grade displays often fail quickly due to:
- Constant exposure to weather and humidity
- Mechanical vibration and impacts
- Continuous, 24/7 operation
The ruggedized design directly address these challenges by improving visibility, strengthening the assembly, and protecting internal components. The Hong Kong East Rail deployment demonstrates what this can mean in practice: more than 12 years of service and over 80,000 hours per screen in a demanding, real-world environment.
Why faytech Leads in Optical Bonding and Long-Lifetime Displays
Nowadays, faytech’s strong focus and strength are focused on the Optical Bonding, which is heavily built on top of the rugged installations & designs like the one in the Hong Kong Metro:
- In-House Control. From the proprietary Clear-Bond adhesive to specialized bonding lines and cleanroom production, faytech maintains full control over critical processes.
- Proven Long-Term Installations. The Hong Kong East Rail project is a real-world reference for multi-year, high-usage outdoor operation. This is not just a laboratory benchmark.
- Custom Engineering Expertise. Tailored EMI shielding, cable designs, mechanical layouts, and certification support enable compliance and reliability in regulated sectors like transit.
- Complete Outdoor Solutions. High-brightness panels, IP-rated enclosures, anti-UV treatments, and system integration support are combined into turnkey solutions for global customers.


Applications That Benefit from faytech’s Optical Bonding
faytech’s optically bonded displays are well-suited for:
- Mass Transit and Transportation. Platform and concourse information systems that must remain legible, robust, and low-maintenance in high-traffic areas.
- Outdoor Kiosks and Signage. Public terminals and digital advertising exposed to sunlight, dust, and moisture.
- EV Charging Stations. Always-on user interfaces that need clear readability and resilience in outdoor parking and roadside locations.
- Industrial and Harsh Environments. Rugged HMIs deployed in dusty, humid, or vibration-prone facilities, indoors or outdoors.
The Hong Kong East Rail installation shows how these technologies perform long-term when failure is not an option.
