Head-Up Displays The head-up display (HUD) provides drivers with virtual images of information such as vehicle speed, in front of the windshield. The HUD is expected as a next-generation display because: It can shorten the driver’s eye movement time. The driver can focus on the front of the vehicle, compared with conventional instrument clusters. It’s easier for drivers to focus on the HUD, since the distance between the driver’s eyes and the image is longer than that of conventional instrument clusters. DENSO’s HUDs can show a variety of information including vehicle speed, car navigation information and images of the night view system (see below).

DENSO Technology – Leading the World

• In December 2003, DENSO introduced the world’s first HUD that can selectively show either information such as vehicle speed or night view system images. The night view system emits near-infrared radiation in front of the vehicle and detects the reflected radiation. This creates the image displayed by the HUD; helping drivers to see the view ahead in the nighttime.

Benefits and Features

• Safely provides drivers with driving information
  • The HUD can shorten the driver’s eye movement time, compared with conventional instrument clusters.
  • With the HUD, the distance between the driver’s eyes and the image is longer than that of conventional instrument clusters, making it easier to focus.
• High-quality image
  • The concave mirror, which reflects light from the indicator toward the windshield, uses progressive focus points –DENSO-developed technology– to provide a high-quality image without distortion.
• High and uniform image brightness
  • The indicator emits light uniformly with high brightness toward the concave mirror, allowing drivers to see the virtual image, even in the daytime.
