Ceres Holographics Shows Transparent Windshield Displays and More at CES 2025

23 January 2025

Ceres Holographics used CES 2025 to showcase the capabilities of its transparent automotive display solutions. These are based on their Holographic Films coupled with a projection source to create a Heads-up Display for the driver or passengers. Their digital master approach enables the fabrication of large holographic films. Demos with multiple projector technologies and film sizes were shown along with future tech needed to reduce the HUD volume. Full video news report below.

Holographic films that contain Holographic Optical Elements (HOE) are an emerging class of optical device that can be used to bend, shape, or direct light. Simple HOE structures like gratings are used in waveguides to capture, direct and expand images for Augmented Reality (AR) devices. When integrated into the windshield of an automobile, and illuminated by an LED projector they create the images the driver sees on a transparent background without having to wear any additional head gear.

For the automotive HUD application, Ceres’s holographic film acts like a projection screen for the LED projector. While this may sound like a simple optical function (diffusion) to record, it is way more complicated. For example, the light from the LED projector arrives at the holographic film at different angles and distances from the projector. This projected light must be redirected into a fairly narrow driver eyebox with good uniformity and color fidelity. It must also maintain high resolution, be bright, but also highly transparent to external light.
