Continental introducing 3D display
Continental announced its volume-production display, featuring autostereoscopic 3D technology, is making its way to the market via the HMC Genesis GV80 high-line variant. On the screen, the technology displays 3D scales, pointers and objects, for example displaying a stop sign warning in the driver’s line of sight. No special glasses are required to see the 3D warning signal. Instead, the company uses parallax barriers—slanted slats that divide the image for the viewer—as if looking at real objects, two different, slightly offset views reach the right and left eye, resulting in the 3D image.
The company says its interior camera, which detects the driver’s line of sight and adjusts the 3D views to their precise head position, plays an essential role. To prevent drivers from focusing their attention on the 3D screen for too long, the camera also employs attention detection to identify potential moments of driver distraction or fatigue. With the 3D visualization of the instrument cluster, the company wants to prevent the driver from being overloaded with information provided by advanced driver-assistance systems, conventional displays, communication services, and infotainment applications.
“With our volume-production display featuring autostereoscopic 3D technology, we are raising human-machine interaction to a whole new level and laying the foundations for intuitive communication in the connected cockpit of tomorrow,” said Dr. Frank Rabe, Head of the Human Machine Interface Business Unit at Continental. “To ensure that this gain in safety and comfort does not come at the expense of a lean electronics architecture, we integrated various displays in the center console or dashboard into our Cross Domain Hub.”
Cross Domain Hub removes boundaries between individual screens and control units
The Cross Domain Hub is the basis for the 3D display being used in the HMC Genesis. The company says the industry is moving away from numerous individual control units to a few high-performance computers. Continental's solution integrates all displays into a single unit. The driver will be able to distribute content across multiple displays, for example by means of gesture control, dragging navigation maps from the front passenger’s display onto their own screen and arranging according to the driver preference. In automated driving mode, the displays merge across the entire width of the cockpit and offer all the services and apps that are otherwise only available on the front passenger’s side.
The company says it is currently developing a new 3D display based on the natural 3D Lightfield Technology from Silicon Valley-based Leia Inc. With this technology there is neither the need for cameras detecting head movement nor 3D glasses. As a result, the company says that the Natural 3D Display not only saves weight, space, and costs, but also opens up an entire world of digital services to all the passengers in a connected car. Instead of the parallax barriers described above, this system relies on Diffractive Lightfield Backlighting (DLB) technology. An optical waveguide with diffraction grating and nanostructures beneath the display panel creating a natural 3D effect by bending the light. Continental is adapting this technology for use in vehicles. The system is planned for production by 2022.
