56.4: A Head-Up Display Illuminator Design and Virtual-Image Estimation Method

We proposed a novel lighting system with optical lens of the car head‐up display (HUD) and the camera CCD estimation method of the projection virtual image. This novel optical lens lighting system shows up to 0.8 million nits BLU brightness with 3M DBEF4, 15° full viewing angle and better uniformity...

Description
Summary:We proposed a novel lighting system with optical lens of the car head‐up display (HUD) and the camera CCD estimation method of the projection virtual image. This novel optical lens lighting system shows up to 0.8 million nits BLU brightness with 3M DBEF4, 15° full viewing angle and better uniformity. Besides, we set up a new measurement method to estimate projection virtual image performance and the tolerance with human factor test is within 4%. Finally, we have demonstrated AUO HUD combined with the optical lens lighting system and displayed average 4.5 X projection image during 1418 mm distance from the driver. And the virtual image brightness within 50 * 130 mm2 eye‐box is average 8900 nits.
