DENSO has developed the world’s largest projection-size TFT LCD Head-up Display (HUD). HUD technology projects important information such as vehicle speed, onto the windshield so drivers can obtain critical information while keeping their eyes on the road. DENSO plans to introduce the new larger-display HUD to the global market in the 2015 timeframe.
The HUD is embedded in the dashboard behind the steering wheel. The image on a LCD panel is reflected by a mirror, then reflected again by a concave mirror to magnify it, and then reflected by the windshield so that the driver can see an image. The HUD technology is expected to help reduce traffic accidents by minimizing the driver’s eye movement, and is expected to further diffuse in the market.

DENSO’s new HUD can coordinate with sensor-based technologies to inform drivers the presence of pedestrians ahead. The new HUD also can coordinate with vehicle navigation and can project virtual directions and lane guidance on the windshield to provide information to the driver more quickly and naturally.
DENSO designed the positions, colors, and other indication factors of HUD to make for a more natural driving experience. DENSO also has raised display brightness by a factor of two to provide a clearer and brighter image even in direct sunlight.
HUD is among one of the Human Machine Interface (HMI) solutions that DENSO is researching and developing to help reduce driver workload. Currently the company is researching how to quantify driver workload to create a better system solution for its customers.
Earlier this year, the company launched its 7.5-inch full-color TFT HUD and currently is working on other vehicle programs in the Asian, North American and Europeans markets.
DENSO has researched and developed HUD since the late 1980s and first manufactured the technology in 1991. DENSO will exhibit the new HUD in its booth at the 19th Intelligent Transport Systems World Congress 2012 in Vienna, Austria.
