Patent ID: 8162711

Claim:
A method for the manufacturing of a field-emission display, comprising the steps of: arranging an electron-emission receptor in an evacuated chamber; arranging a wavelength converting material in the vicinity of the electron-emission receptor; and arranging an electron-emission source in the evacuated chamber, the electron-emission source adapted to emit electrons towards the electron-emission receptor, wherein the electron-emission source is formed by: providing a substrate; forming a plurality of ZnO-nanostructures on the substrate, wherein the ZnO-nanostructures each have a first end and a second end, and the first end is connected to the substrate; arranging an electrical insulation between and around the ZnO-nanostructures to electrically insulate the ZnO-nanostructures from each other, partially exposing the second end of the ZnO-nanostructures such that a small portion of the nanostructures is above the electrical insulation; connecting an electrical conductive member to the second end of a selection of the ZnO-nanostructures; arranging a support structure onto the electrical conductive member; and removing the substrate, thereby exposing the first end of the ZnO-nanostructures.
