Traditional column-to-column displays could become a thing of the past as early as 2027
- Hyundai Mobis launches Kia EV9 equipped with holographic head-up display.
- It uses a projector and special film to display images and videos on the windshield.
- Pre-development was completed last year and mass production could begin as early as 2027.
BMW used CES to unveil its new panoramic iDrive system, which features a pillar-to-pillar display at the base of the windshield. Now, Hyundai Mobis is upgrading them with a holographic head-up display that projects information onto the base of the windshield.
While the two ideas are similar, Hyundai Mobis’s idea is much more advanced and has the advantage of being transparent. Installed on the Kia EV9, it relies on high-tech projectors and a transparent film affixed to the windshield that is just 100 microns thick, making it slightly larger than a strand of hair.

The film, called a holographic optical element, “uses the principle of diffraction of light (light bends from its original path to reach its destination) to effectively transmit the images and videos projected by the projector to the position of people’s eyes. The driver’s and passenger’s seats .” It also offers a privacy mode to prevent drivers from being distracted by what their passengers are watching.
While the film has been applied to the bottom of the windshield, Hyundai Mobis notes that other configurations are possible. This involves placing holographic optics on the sides of the windshield so that the holographic head-up display will “work like a smartphone’s curved edge screen.”
The high-tech HUD is composed of multiple parts and can display the instrument cluster, side camera views, navigation information and entertainment, etc. This eliminates the need for a traditional instrument cluster as well as a front passenger display. Modern Mobis adds to the display in a bright outdoor setting and looks like a traditional glass window from the outside.
The company has been working with Zeiss to develop the display for some time, with “pre-development” completed in the first half of 2024. It is currently expected to achieve mass production as early as 2027. Hyundai Mobis has previously stated that the global holographic HUD market may reach 7 million units by 2030.
