Motorola Spindt tip FEDs operating for 10,000 hours

摘要

At Motorola, full-color, Spindt tip field emission displays (FEDs) have now been running continuously for more than 10,000 hours on our life test racks. These displays demonstrate that adequate FED lifetime can be achieved using Spindt tip technology, color phosphors, and high anode voltage (4 kV). Motorola's spacer technology also remains invisible after 10,000 hours. We discuss these results and the dependence of lifetime on important variables.
