HUD systems are becoming increasingly available in production cars on their windscreens, and usually offer speedometer, tachometer and navigation system displays.
How does head-up display work?
HUD technology often depends on the system. Some vehicles use transparent phosphors on the windscreen that reacts when a laser shines on it. With the laser off, no information is shown, but when the light is on, this is projected on to the glass. A projector embedded in the car dashboard sends a transparent image onto the windscreen by bouncing off a series of mirrors, before being magnified so it is legible to drivers. This can be adjusted to meet their visual and height requirements.
The All-New Kona features a combiner head-up display
For the first time in a Hyundai, the All-New Kona’s new combiner HUD projects relevant driving information directly to the driver’s line of sight. This allows for the faster processing of information while keeping attention on the road ahead.
HUD in the Kona supports safe driving by displaying information such as speed, navigation commands and the car’s fuel levels, as well as safety warnings from assistance systems such as Lane Keeping Assist and Blind-Spot Collision Warning. In addition to this, HUD also projects information about the in-car radio and audio.
