Volume Production of Holographic Optical Elements for Windscreens, Enabling the Next Generation of Automobile Head-up Displays
Head-up Displays (HUDs) represent the next generation of information display in cars. Every major automotive manufacturer (OEM) is seeking low-cost, compact HUDs that can display information across a wide field of view (FOV).
However, existing solutions based on conventional optics cannot meet these market needs. Using current technology, a HUD projector system covering the driver’s required FOV would be far too bulky for all but the largest vehicles and the cost becomes inviable.
"Our HOEs dramatically reduce the size of HUD projection systems"
Ceres holographic mastering technology breaks the link between size and performance by replacing part of the HUD systems optics with a photopolymer Holographic Optical Element (HOE), which can be laminated inside the vehicle windshield. The optical power delivered in the windshield dramatically reduces the size of the required projection system, allowing windshield based driver and passenger display systems to be fitted to any vehicle. Our customers have a stated aim to start installing HOE based displays in cars by 2022/23.
However, to produce our HOEs in the volumes and format required by the market we must adapt our replication machinery to work on a continuous roll-to-roll basis and then industrialise the HOE integration process in partnership with our customers’ preferred windshield interlayer and lamination partners.
The VIEW AHEAD project will accelerate the development of the manufacturing technology and industrialisation of the film integration processes. With help from Horizon 2020, Ceres are delivering a game-changing technology to a hungry market.
