Turning the Windshield into a Display
A projection system with fluorescent conversion technology allows the size and angle of an automotive display to be almost limitless.
by Ted Sun and Jianqiang Liu, SuperImaging
A major problem with ever-more-sophisticated automobiles is the growing amount of information provided to drivers. Increased information in dashboard displays diverts eyes from the road, creating a distraction that can lead to accidents. Head-up displays augment dashboard information but are limited in size and viewing angle.
A full-windshield projection system using a fluorescent conversion technology could help alleviate this problem. SuperImaging Inc. of Fremont, Calif., recently developed a system in which the entire windshield (or any substrate) is covered with a special fluorescent coating that is fully transparent. The area of coverage becomes an emissive screen for the transparent display, called a TransPlay. The film converts a UVA dark image projected from either a digital light processor (DLP) or 2-D laser scanner into a fluorescence visible image on the windshield substrate...
