Advanced HUD Technology: Multiple Independent Holograms for Windshields

Advancements in automotive technology continue to push boundaries, with the latest innovation being a triple configuration transparent display that is set to revolutionize the driving experience. Each separate display area, measuring up to 400mm by 300mm, contains a specifically programmed holographic optical element (HOE), resulting in the industry’s largest field of view Heads-Up Display (HUD).

One of the key features of this cutting-edge display is its ability to be configured at specific (off-axis) viewing angles within the windshield. This allows for information and content to be shown to the intended user – whether it be the driver or passenger – without obstructing the view of the road ahead. The technology is currently being showcased at a meeting in Cologne, where attendees are getting a firsthand look at its capabilities.

The transparent display is manufactured using Ceres' HoloFlekt 1400mm wide roll-to-roll machinery, which utilizes an advanced photopolymer film in a proprietary stack designed for automotive applications. Each holographic optical element is produced in a single piece of windshield-sized film, which is then laminated inside the windshield for seamless integration into the vehicle. When coupled with compact light projection units from third-party suppliers, the result is a full-color, wide field-of-view transparent display HUD.

Andy Travers, CEO of Holographics, expressed his excitement about the potential of this technology, stating, "With our HoloFlekt technology, OEMs can transform any windshield into an ultra-bright, full-color, and compact multi-display HUD. Safety, operational information, navigation prompts, and infotainment content can all be displayed clearly and non-distractingly, regardless of external lighting conditions. The off-axis viewing angles required for this level of performance can only be achieved through holography."

Ceres has made the multi-HOE solution available for implementation in proof of concept (PoC) projects with select OEMs and Tier One suppliers. The company, founded in 2009, has developed software-controlled hologram mastering and manufacturing capabilities that enable novel displays for mass-market applications.
