  • Field emission display
    Patent number: 8162711
    Abstract: The present invention relates to a method for the manufacturing of a field-emission display (300), comprising the steps of arranging an electron-emission receptor (302) in an evacuated chamber, arranging a wavelength converting material (304) in the vicinity of the electron-emission receptor, and arranging an electron-emission source (100) 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 to electrically insulate the ZnO-nanostructures from each other, connecting an electrical conductive member to the second end of a selection of the ZnO-nanostructures, arranging a support structure onto of the electrical conductive member, and removing the substrate, there
