Head-up displays ready for the automotive market

Head-up displays ready for the automotive market Formerly used only in the cockpits of multimillion-dollar jet fighters, head-up displays (HUD) now are finding their way into family cars, with navigation and driver-assist functions helping drive the automotive HUD market to expand by more than a factor of seven from 2012 to 2020.

Worldwide sales of cars equipped with HUDs are set to rise to 9.1 million units in 2020, up from 1.2 million in 2012, according to a new report from IHS Automotive. Sales this year are forecast to climb 7 percent to 1.3 million units, as presented below.

“Projecting an image that floats about 2.5 meters, or 7.5 feet, in front of motorists' eyes, HUDs are the optimal display technology for cars—with studies having shown that this distance delivers the fastest response time for viewers,” said Ben Scott, technology solutions analyst for IHS Automotive. “Apart from showing speed and warning signals, HUDs are perfectly suited for displaying navigation information or advanced driver assistance system (ADAS) data, allowing drivers to access critical material while keeping their eyes on the road.”

Only 2 percent of automobiles sold in 2012 had HUDs. However, by 2020, that rate will rise to 9 percent. Japan had the highest fitment rate of car HUD systems in 2010, but Europe is expected by 2020 to take the lead.

HUDs make themselves useful

By combining the HUD unit with a vehicle's GPS system, the driver can display map, turning and even speed-limit and traffic-sign information on a car’s windshield. For ADAS, blind-spot detection warnings can be presented on the HUD, for example.

HUDs are especially useful for providing warning information such as oil level or tire pressure, or for alerting the driver that the car is too close to a vehicle in front, made possible by integrating HUDs with adaptive cruise control. Other uses are possible as well, such as showing text messages from mobile phones or displaying track information from MP3 players.
