Head-up display illuminates safety, navigation and handling features

TROY, Mich. [PRNewswire] -- A head-up display (HUD) technology from Asahi Glass, Nippon Seiki and DuPont Automotive is available as an option on several GM vehicles including the Pontiac Grand Prix, Cadillac STS and Chevrolet Corvette. It comes standard on the Cadillac XLR and the new 2006 Chevrolet Corvette Z06, launching in the fourth quarter of 2005.
The distortion-free, head-up display (HUD) communicates driver-selected information, such as navigation, performance features as well as vehicle speed to the driver. This year, the HUD incorporates a new Track Mode setting that presents real-time information on lateral acceleration -- better known as G-Force. In Street Mode, driver-selectable settings include vehicle and engine speed, direction, turn signals, gear position, audio settings and even turn-by-turn directions on vehicles equipped with a navigation system.
At the center of the HUD technology is an "interlayer" of DuPont™ Butacite® PVB that acts as the screen onto which the HUD information is projected. This interlayer is called the DuPont™ Wedge™ because of its angular cross-section.
Laminated between two layers of glass, the Wedge is transparent to allow distortion-free forward vision, but also is able to reflect the HUD projection for viewing by the driver. The virtual image appears to float in the driver's line of sight near the front of the car, minimizing refocus time.
Virtual image location and brightness can be adjusted to the driver's preference. Together, these features help to reduce driver distraction, enhancing safety.
The Wedge was developed through close cooperation with the GM engineering team, windshield supplier Asahi Glass Co. and Nippon Seiki, which supplies the HUD projector and served as package integrator.
"This is a great example of suppliers working together to add value to the OEM," said Jeff Dickson, general manager, sales, for Nippon Seiki International Ltd. "As we were adding great new features, such as a wide array of user-selectable displays, it was important that the image be as crisp and clear as possible. The laminate is a critical factor in achieving that goal.”
GM was the first automaker to make HUD commercially available on vehicles.
"More and more, automakers are incorporating HUD technology in new vehicles," said David Lee, marketing manager for DuPont Automotive Glass Laminating Solutions (GLS) Americas. "Automakers tell us consumers appreciate the benefit of seeing critical information without having to look away from the road, primarily because the information can help reduce distraction and reaction times."
