Abstract:
A method of making a field emission display, said field emission display having a baseplate, emitter sites, semiconductor junctions, and a display screen, said method comprising:depositing an opaque light blocking layer on the baseplate between at least one semiconductor junction of the semiconductor junctions and the display screen to block photon bombardment by at least one of the display screen, an environment of the field emission display and the display screen and the environment of the field emission display from the at least one semiconductor junction, the opaque light blocking layer comprising an insulative light-absorbing material, said opaque light blocking layer preventing photons from the at least one of the display screen, the environment of the field emission display, and the display screen and the environment of the field emission display from striking the at least one semiconductor junction of the semiconductor junctions to prevent the photons from effecting the at least one semiconductor junction of the semiconductor junctions.
