Ceres unveils holographic multi-display HUD windshield

Ceres Holographics, a provider of holographic technology and solutions, in collaboration with Eastman Chemical Group, has recently unveiled its fully integrated windshield featuring multiple holographic optical elements (HOEs) inside a single laminate construct.

According to Ceres, the solution utilizes its ‘HoloFlekt’ technology to produce films with multiple HOEs that are then seamlessly laminated inside windshield glass using Eastman’s proprietary lamination techniques.

Ceres’ HoloFlekt manufacturing process replicates custom-designed holographic optical elements onto a windshield-sized proprietary photopolymer film. This method offers a more cost-effective and scalable way to produce multi-display HUD areas on any glass surface, according to the company.

Eastman’s proprietary lamination process then allows integration of Ceres’ finished HOE-imprinted film into a windshield. Once the windshield is combined in the car, content can then be projected by a compact LED projector within the vehicle’s instrument panel for each display area.

“We have been working with Ceres for several years to understand the implementation requirements for their HOE films to be integrated in automotive approved windshields in a scalable way,” said Romain Delorme, Global HUD segment market manager at Eastman. “After having produced several proofs of concepts of single HUD display for OEMs, we believe this current implementation of multi-HOE films for transparent displays expands the possibility even further and will be attractive to OEMs who want to differentiate their vehicles, enhance operational safety, and upgrade the overall user experience,”

Ceres stated that their method of implementing HoloFlekt film permits the creation of multiple display areas in a single windshield. These display areas can be customized to match the specifications of the original equipment manufacturer (OEM) in terms of size, position, and viewing angle. Each individual display area contains a programmed HOE, which allows for a larger field of view HUD with more flexibility in system geometry. Ceres claims that this particular capability can only be achieved through holography, as the technology enables precise manipulation of light that goes beyond the capabilities of traditional optics.

“Through deep technical collaboration with global supply chain expert Eastman and our ongoing engagement with top OEMs, we are now ready to bring an automotive-grade holographic transparent display HUD solution to market,” said Andy Travers, CEO of Ceres. “With increasing concerns about safety distractions caused by other types of in-car information displays, such as large pillar-to-pillar touchscreens and other ‘look down’ displays, this HUD technology presents a viable and attractive alternative.”

Ceres will be showcasing its concept demonstrator kit at Car.HMI EuropeThis week, there will be a demonstrator kit available in Berlin, Germany. It aims to allow OEM HMI and UX designers to explore the capabilities of transparent display HUDs and gain insight into the potential placement and presentation of information.
