Denso says it has developed a thin-film transistor (TFT), liquid-crystal head-up display (HUD) that is the world's largest automotive head-up display with a near 24-inch projection. The product is available to the market now and will be featured on the 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, Denso says 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, it is claimed.

Denso says it has produced HUDs since 1991.
