Abstract:
A method of constructing a cold cathode field emission display for preventing junction leakage therein, the field emission display having a baseplate, emitter sites, semiconductor junctions, and a display screen, the method comprising:forming an opaque light-blocking layer between at least one semiconductor junction of the semiconductor junctions and the display screen for blocking 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 for 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.
