ZEISS, tesa, Saint-Gobain Sekurit, and Hyundai Mobis Form Alliance to Advance Holographic Windshield Displays

Four major industrial companies announced a supply-chain alliance on February 3, 2026, aimed at making holographic windshield display technology commercially viable for automotive OEM production. ZEISS, tesa, Saint-Gobain Sekurit, and Hyundai Mobis formed the QuadAlliance to provide automotive manufacturers with an end-to-end solution for holographic windshield displays (HWD) at production scale.

Holographic windshield displays project instrument and navigation information directly onto the windshield in the driver's forward field of view, combining head-up display (HUD) function with the optics of the glass itself rather than relying on a separate projector and combiner. The alliance combines complementary expertise: ZEISS contributes optical system and holographic film technology; tesa provides adhesive film solutions for integrating holographic elements into laminated glass; Saint-Gobain Sekurit, a major automotive glazing manufacturer, contributes windshield production capability; and Hyundai Mobis adds systems integration and automotive electronics expertise.

The alliance aims to give OEM customers a single integrated source for a complete HWD system rather than requiring them to coordinate separately with multiple suppliers across the optical, adhesive, glass, and electronics supply chains. Its members position the offering as a production-ready solution rather than a research prototype.

For the auto glass aftermarket, the emergence of holographic windshield displays raises a new set of service challenges. Windshields that integrate holographic optical elements cannot be treated as interchangeable with conventional glass. An HWD-equipped windshield that is damaged and requires replacement will need an OEM-sourced replacement that preserves the holographic layer geometry and the calibration of the associated display system. Aftermarket suppliers would need to replicate the holographic element specification precisely—a significantly higher bar than conventional glass matching.

The QuadAlliance announcement reflects a broader industry direction in which the windshield is evolving from a passive structural and safety component into an active information display surface. This trajectory has direct implications for training, parts sourcing, calibration equipment, and pricing in the glass replacement market. Shops that stay informed about these technology developments will be better positioned to advise customers and plan their own capability investments.
