Hyundai-Zeiss head-up display projects full-scale dashboard

Hyundai Mobis, a leading parts supplier for Hyundai, is taking in-car screen technology to the next level with its latest innovation: a full-width holographic windshield display.

Developed in partnership with German optical giant Zeiss, this new technology could revolutionize how drivers and passengers interact with their vehicles by transforming the entire windshield into a transparent infotainment and driving data display.

“Imagine navigation and driving information unfolding like a panorama across the wide, transparent windshield where the driver’s gaze rests,” says Hyundai Mobis in a press release.

This is precisely what its engineers have established in cooperation with Zeiss. Building on head-up displays (HUDs), the so-called Holographic Windshield Display vastly expands the scope of information available to drivers and passengers.

Seeing different things

Traditional HUDs typically show basic information such as speed and navigation directions, while newer ones have added music playing, warning icons, and customization. But none of these match the size and functionality of Hyundai’s system, which can display menus, entertainment, and even video calls. For example, the driver’s side of the windshield might show critical driving data, while the passenger can watch movies or play games on their own side.

The key to this breakthrough is a micro-thin, transparent film developed by Zeiss applied to the windshield. A compact projector developed by Hyundai Mobis then renders holographic images on the film. The system is designed to ensure that the displays are not distracting, as the driver and passenger will see different content based on their position in the car.

Also on side windows

The display system’s images are nearly fully transparent, achieving 90% transmittance and ensuring clear visibility even in bright conditions. The system is expected to enhance the interior design of future vehicles by removing the need for multiple dashboard screens and creating a more open and minimalist cockpit.

Because of the size of the projector, the holographic system could also be adapted for use on side windows, sunroofs, and even taillights in future applications.

Split viewing technology is already in production since 2010 and was developed by Bosch for the Mercedes S-Class. But hitherto, it hasn’t been applied in the format of a head-up display. As for controls, no information is yet available.

However, it is believed that it could function by gesture control, although this manipulation is referred to as one of the most frustrating car features in J.D. Powers’ annual Tech Experience Studies. Gazing tech is often also applied to holographic interfaces.

In production models by 2027?

For Hyundai, it’s no longer science fiction. “This dream technology, previously seen only in movies, is about to become reality,” Hyundai Mobis officials said. While the invention looks like a distraction bonanza, the holographic windshield display offers significant safety and design advantages, according to its makers. It allows drivers to keep their eyes on the road while accessing vital information.

Hyundai Mobis plans to introduce this technology as early as 2027, initially targeting high-end vehicles. “At first, it will be mainly used in premium models, but the goal is to expand it across various segments,” said Jung Soo-kyung, Hyundai Mobis’ Executive Vice President for Automotive Electronics.
