Display having scrubbed cathodoluminescent layer

摘要

Field emission displays having novel cathodoluminescent layers are disclosed. The cathodoluminescent layers are irradiated with electrons having a density of greater than one hundred microamperes/cm2. Significantly, this results in improved emitter life in a field emission display. The display including the scrubbed faceplate has significantly enhanced performance and increased useful life compared to displays including faceplates that have not been scrubbed.
