摘要
A new current pulse-width control for long-lived ZnSe-white LEDs is presented. Using the defect controlling technique together with high quality ZnSe white LED, it is proved that bright ZnSe white LEDs have exhibited long device life-time exceeding 20000 hrs for its in practical use. It is also evidenced that the present current pulse-width control is not limited in the ZnSe system, but very effective for other widegap semiconductor bright and long-live light emitting devices of GaN and ZnO.
