The W-HUD (Windshield Head-Up Display) is a next-generation human-machine interface (HMI) designed to enhance driver safety and comfort by projecting essential vehicle information directly onto the windshield. Unlike traditional dashboard displays, this windshield-based system uses advanced optical projection technology to create a virtual image that appears at a distance of 2–3 meters ahead of the driver, reducing eye movement and cognitive load during driving.
This W-HUD features exceptional visual performance, including:
- High brightness — ensures visibility even under direct sunlight
- High contrast ratio — delivers sharp, readable text and graphics
- Low eye strain design — minimizes glare and fatigue with optimized color temperature and anti-reflective coating
- Dual-eye parallax ≤1.5mrad — ensures consistent image alignment between both eyes, preventing visual discomfort or motion sickness
- Angular resolution ≥100 PPD (Pixels Per Degree) — provides crisp, detailed rendering of icons, arrows, and numbers
-
The system supports a wide range of content types, including:
- Driving dynamics visualization (real-time speed, RPM, gear position)
- Navigation guidance (turn-by-turn directions, lane departure warnings)
- ADAS alerts (collision warning, blind spot detection, adaptive cruise status)
- General notifications (phone calls, messages, media playback)
Its modular design offers three standard sizes:- 3.1 inch — ideal for compact vehicles and budget-conscious OEMs
- 4.1 inch — balanced performance for mid-size sedans and SUVs
- 5.1 inch — premium option for large vehicles and luxury models
-
The W-HUD is built for harsh automotive environments, withstanding vibrations, temperature extremes (-40°C to +125°C), and exposure to UV radiation. It supports CAN/FLEXRAY communication protocols and can be integrated with ADAS systems, telematics, and voice assistants.Manufactured under IATF 16949 with ISO 26262 ASIL-B functional safety compliance. All units undergo rigorous environmental testing, including thermal cycling, vibration, and salt spray resistance. Supports white-label customization with rapid NPI cycles (14 days) and regional compliance packages (EU Type Approval, China CCC, U.S. DOT).
