Denso displays largest head-up display images to be used in a vehicle environment

4306 Denso Corporation is showing what it says are the largest head-up display (HUD) images to be used in a vehicle environment. Its system – although in a slightly smaller format – has already been installed in 5229 Kia’s new K9 luxury car and Denso says it is in talks with US and European manufacturers over adopting the system.

The image area produced by the HUD on Denso’s stand measures 230 x 90mm, with road information such as speed limits and directions being projected into the driver’s line of sight.

The system has a very high intensity of backlit illumination in order to make the information visible in bright sunlight or snow, with high contrast levels also helping in snowy conditions. Despite this high level of illumination, power consumption is low, with the system requiring only seven watts, said Andreas Prey, Denso’s senior manager, information safety engineering.

The next generation of the HUD will have even higher levels of resolution and intensity, said Prey.

One of the biggest problems preventing the system’s wider implementation is the relatively large amount of space required behind the dashboard for the current system – 4,900 cubic centimetres.
