To project critical driving information onto the windshield for drivers, Denso has developed a Thin Film Transistor (TFT), liquid-crystal Head Up Display (HUD). This Human Machine Interface (HMI) is what the company claims to be the world's largest automotive head-up display with a nearly 24" projection. The product will be released in November 2017 and featured on the new 2018 Lexus LS.
DENSO's new HUD projects a virtual screen approximately three metres ahead of the driver, enabling the driver to more intuitively access key information about the vehicle and its surroundings without changing direction of gaze.
The technology displays not only basic information, such as speed limits and the vehicle's driving speed, but also the locations of pedestrians through external sensors.
It also provides lane guidance assistance by using an automotive navigation system featuring an arrow indicating the appropriate lane to follow at junctions and intersections.
Additionally, the HUD takes into consideration the relative position of information displayed, its colours and other visual effects - all without obstructing driving. Its display is brighter than conventional HUDs to ensure screen visibility in bright, daytime conditions.
HUDs do not require drivers to look far away from the road, and thus are expected to emerge as a key technology for manufacturers across the globe. DENSO has produced HUDs since 1991 and will continue to develop and provide safety products as it pursues creating a society free from traffic accidents.
