In-plane HOEs to enable every transparent surface to become an information display
Another key feature of these diffuser HOEs is Ceres ability to precision program every pixel to an arbitrary light reflecting geometry within the scope of the current master printer. This enables system geometries for on or off-axis projector package arrangements that an be accommodated efficiently in the car. The ultra-small projectors are LED diode based and offer the OEMs the design freedom to think out of the box.
This demo by CERES Holographics at CES2020 showcases a digital windscreen cluster with holographic display, illuminated by a TI DLP Auto projector. A DLP5534-Q1 chipset processes and projects the light onto the CERES holographic film. This is the ideal design for transparent window display applications.
