HUD Enhanced Head-up Display features for improved safety

Editor: Nicole Kareta

Faraday Future, a global shared intelligent mobility ecosystem company, announced additional details on its FF 91 ultra-luxury vehicle, including updates to its head-up display functionality. One of the features includes increased safety.

The Head-Up Display (HUD) has been around for quite some time. The most basic form of a HUD has a picture generator unit (PGU), a series of curved mirrors and optical filters that projects its image to the windshield. This reflected image off the windshield is what the driver sees. Almost all HUDs available in the market today use an liquid crystal display (LCD) as a PGU. The problem is that the light that is seen is polarized at the same angle as the common polarized sunglasses, thus making the HUD difficult, if not impossible, to see in some situations.

Faraday Future (FF) saw this as an issue and opportunity and tried to address it by working with a whole new PGU, one that is not LCD based, but instead digital light processing (DLP) based technology. Instead of using a polarizer structure to act as a shutter for light to pass through, DLP uses very tiny mirrors to direct light in the PGU. Each mirror acts as a pixel, while red, green and blue LEDs are used as a light source. These millions of tiny mirrors in the micro array are switched very slightly to produce the image that is needed. This means FF is now able to provide a unique HUD on FF 91 that works with or without polarized glasses.

Among the other changes made to FF 91 include redundant core drive information on the HUD and instrument cluster for increased safety: Users will now see speedometer and other core drive information on both the HUD and the instrument cluster. In addition, FF 91 will now also have optimized steering wheel controls and HUD menu: the steering wheel interaction with the HUD and the HUD menu itself has been simplified for easier control.

FF 91 is slated to have the largest heads-up display in the industry that projects information as if it were 2.7 m in front of the driver to help keep the driver’s eyes on the road. Below the HUD is the instrument panel, which stretches 11.6 in, wrapping around the driver’s periphery and providing a synchronized experience with the HUD.
