Holographic windshield display turns car glass into a screen

ZEISS has announced a collaboration with LG Chem to bring a transparent holographic windshield display (Holographic Windshield Display, HWD) to market—an innovation designed to turn the car’s glass into a full-fledged screen. According to the developers, the technology rethinks what windshield glass can do and points toward a future where information is cast directly onto the road.

The HWD system can show key driving data right on the windshield without the bulky optical modules typical of conventional HUDs. That not only helps keep the driver’s attention on the road, but also tidies up cabin ergonomics. For passengers, the glass can become an interactive media surface that displays content visible only from their side—such as video or navigation prompts—without distracting the driver. The idea is simple and convincing: less visible hardware, more information where it matters.

As part of the partnership, ZEISS and LG Chem will develop industrial production of photosensitive polymer films used in HWD. These materials deliver high transparency, accurate rendering, and resistance to external influences. ZEISS brings its optical know-how, while LG Chem contributes its expertise in advanced polymers and industrial solutions.

The companies note that their joint work will be part of the ZEISS Micro-Optics Empowerment ecosystem, aimed at bringing microstructural technologies to transportation, digital displays, and wearable electronics. Over time, the technology could become a benchmark for premium vehicles and lay the groundwork for smarter, safer interfaces between driver and machine.
