Abstract
Full-color fluorescent display devices are demonstrated using a near-UV (n-UV) light-emitting diode (LED) and various fluorescent films. ZnS:Ag (blue), ZnS:Cu,Al (green) and ZnCdS:Ag (red) powdered fluors and mixtures of them are dispersed in poly-vinyl-alcohol aqueous solutions, and fluorescent films are prepared by spin coating the suspensions to glass slides. The n-UV light emitted from a blue LED with a high injection current is irradiated onto the films, and the three primary colors and white color are easily obtained.Keywords
