Abstract:
In a field emission display having a baseplate, emitter sites, semiconductor junctions, and a display screen, a method for reducing junction leakage from the semiconductor junctions, said method comprising:forming an opaque light blocking layer on the baseplate between at least one semiconductor junction of the semiconductor junctions and the display screen to protect the at least one semiconductor junction of the semiconductor junctions from photon bombardment from the display screen and from an environment of the field emission display, the opaque light blocking layer comprising one of an insulative light absorbing material and a conductive light absorbing material; andpreventing photons from one of the display screen, the environment of the field emission display screen, and the display screen and the environment of the field emission display screen from striking the at least one semiconductor junction of the semiconductor junctions thereby preventing the photons from effecting the at least one semiconductor junction of the semiconductor junctions during use of the field emission display.
