Envisics built a real holographic windshield display

What you see

Envisics, a company spun out of research at the University of Cambridge, builds head-up displays that project imagery onto a vehicle’s windshield for the driver to see while looking at the road. In January 2021 the company and Panasonic Automotive announced a joint development agreement, and the press release states that Envisics’ ‘first generation laser holographic technology is installed in more than 150,000 vehicles worldwide.’ A driver sees navigation arrows, speed readouts or hazard warnings that appear to sit at a distance in front of the car, without any headset; the display exists only within the windshield’s field of projection, not floating freely in the cabin or visible to anyone outside the vehicle.

How it works

The company’s own technology page, describing its current product as retrieved on 16 September 2026, calls it ‘Holographic Waveguide Technology’ and states the system ‘compensates the windshield distortion with an ultra-thin optical element and mitigates glare and straylight’ using a customized flat countermeasure, delivering images ‘displayed at multiple distances simultaneously.’ The 2021 press release describes the underlying approach as ‘dynamic holographic technologies’ that ‘harnesses the power of holography and laser-based light sources,’ naming Envisics a ‘dynamic holography pioneer’ rather than a maker of a simple reflected image.

Viewing conditions and limits

The 2021 release states the technology was, at that point, already installed in more than 150,000 vehicles, with a stated second generation expected in the market in 2023 — both company-stated figures, not independently audited counts. The display depends on the windshield’s own optical geometry and the driver’s seated eye position, since the system is built specifically to compensate for windshield distortion from that vantage point; the technology page as retrieved does not state a field of view or maximum viewing distance figure. As of 22 April 2026, Envisics’ own site posted a notice that the company had entered administration under the UK Insolvency Act 1986, a change in corporate status separate from the display technology itself.

What it is not

Envisics’ own material describes a real interference-based holographic optical element used to steer laser light through a windshield, a materially different mechanism from a simple reflected head-up display that bounces a projector image off angled glass. Because the system is fixed to a vehicle’s windshield and calibrated to the driver’s seat, it is also not a free-standing hologram a passenger elsewhere in the car, or a bystander outside it, would see in the same way.

• Does the vendor describe the mechanism as holographic interference, or as a simpler reflected or projected image?
• Is a claimed installed-vehicle count or launch-year figure the company’s own statement, and can it be checked against another source?
• What is the current corporate and operational status of the company behind a described automotive display technology?

Envisics’ windshield displays are one of the few entries in this guide where a company’s own ‘holographic’ label matches a cited technical description of genuine interference-based optics, even as the company’s own site now also documents its 2026 entry into administration.
