In modern commercial and residential buildings, elevator displays are more than just functional indicators — they are an essential part of the building’s aesthetic and user experience. At Nanjing Zhuye Elevator Parts Co., Ltd, we specialize in providing high-quality, custom elevator display solutions compatible with all major elevator brands worldwide. Recently, we successfully delivered a custom 4.3″ TFT Duplex Elevator Display for an Otis elevator modernization project in Thailand, demonstrating our full OEM/ODM capability for international clients.
Project Overview: Custom 4.3″ TFT Duplex Display for Otis Elevator in Thailand
The Client’s Challenge
A commercial building in Thailand was undergoing a comprehensive elevator modernization project. The existing Otis elevators required a visual upgrade to match the building’s newly renovated interior. The client needed a modern, high-definition display that could seamlessly integrate with the existing Otis duplex control system while providing clear, customizable information to passengers — including floor numbers, directional arrows, and safety icons.
Our Custom Solution
Our engineering team designed and manufactured a custom 4.3-inch TFT LCD duplex display tailored specifically for this Thailand project. The display features a sleek, high-contrast interface with a dynamic blue abstract background, large white floor numerals, and integrated brand and safety elements. Key customizations included:
- Duplex System Compatibility: Fully compatible with Otis duplex elevator controllers, ensuring synchronized operation between two elevator cars.
- Custom UI Interface: A modern blue abstract background with large, highly legible white floor numbers (e.g., “26”) for maximum passenger readability.
- Brand Integration: The “OTIS” logo is prominently displayed on the screen, maintaining brand consistency throughout the building.
- Safety Indicators: A clear “NO SMOKING” icon is integrated into the UI, addressing the building’s specific safety requirements.
- Plug-and-Play Wiring: Custom wiring harnesses were provided to ensure quick and error-free installation by local technicians in Thailand.

Why Choose Custom TFT Displays for Elevator Modernization?
1. Enhanced Passenger Experience
A full-color TFT display provides a significant upgrade over traditional LED or dot-matrix indicators. The vibrant colors and high resolution make floor information easier to read at a glance, improving the overall passenger experience and reducing confusion in busy buildings.
2. Seamless Brand and UI Customization
With our OEM/ODM customization service, building owners and elevator maintenance companies can display custom logos, specific color schemes, multilingual text, or important safety announcements directly on the elevator screen. As demonstrated in this Thailand project, we can replicate or create entirely new UI designs to match any brand identity or building requirement.
3. Cost-Effective Elevator Modernization
Upgrading the elevator display is one of the most cost-effective ways to modernize an elevator without a full overhaul. Our custom displays are designed as drop-in replacements for existing Otis, KONE, Mitsubishi, and other brand displays, meaning they can be installed without replacing the entire elevator control system. This significantly reduces modernization costs and downtime.
4. Industrial-Grade Reliability
Manufactured in our ISO-certified facility in Nanjing, China, our TFT displays use industrial-grade components designed to operate 24/7 in demanding elevator environments. Every unit undergoes rigorous quality control testing before shipment to ensure long-term reliability in any climate, including the tropical conditions of Southeast Asia.
