In-vehicle head-up displays (HUDs) are now being marketed. Such a HUD is intended as an augmented reality (AR) display that provide a safe driving environment by showing information derived from vehicle sensor data. A laser HUD is optimal for an AR display because it can effectively call the information it displays to the driver’s attention and displays a seamless image with a wide color gamut and high brightness contrast. We have developed a projection unit for an automotive laser HUD and have achieved high image quality and reliability, which were previously issues with laser projection units, by developing a new screen and two-axis micro-electromechanical systems (MEMS) mirror.
