Scanning beam display systems based on scanning light on a fluorescent screen. The screen can include fluorescent materials which emit visible light under excitation of the scanning light to form images with the emitted visible light. Multiple lasers can be used to simultaneously scan multiple laser...http://www.google.ca/patents/US20070206258?utm_source=gb-gplus-sharePatent US20070206258 - Optical designs for scanning beam display systems using fluorescent screens
