High-transmittance holographic display and interactive technology–integrated multifunctional windshield system

Technical Features

——————————————

The front windshield is evolving into an intelligent interface that integrates high-transmittance holographic display, interaction, and sensing, enabling multifunctional capabilities such as information projection, passenger‑specific privacy partitioning, and embedded cameras. Conventional automotive HUDs suffer from low transparency (typically below 70%), bulky form factors, and narrow fields of view, making it difficult to meet the future smart cockpit’s demands for safety, user interaction, and spatial aesthetics. In contrast, the next‑generation high‑transmittance holographic display technology—based on holographic optical elements (HOE)—integrates an ultra‑thin holographic film into the windshield, achieving a light transmittance of up to 95% and fundamentally redefining human–vehicle interaction. This truly realizes the vision of “glass as screen, glass as sensor.”

Core Advantages

Interaction Upgrade: Combining AI-powered voice and gesture recognition enables contactless operation.
Security Enhancement: The windshield itself can serve as an “invisible camera,” capturing the driver’s state (DMS) and in-cabin occupant conditions (OMS) in real time, and integrating with ADAS.
Entertainment Section: Front-seat passengers can view independent content through the same glass panel without obstructing the driver’s line of sight.
Future Potential: The “Horizon Panoramic Display” concept envisions transforming the windshield into a dynamic information canvas, enhancing immersion.
