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 (302), and arranging an electron-emission source (100) in the evacuated chamber, the electron-emission source (100) adapted to emit electrons towards the electron-emission receptor (302), wherein the electron-emission source (100) 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, thereby exposing the first end of the ZnO-nanostructures. Advantages with the invention include for example increased lifetime of the field-emission display as there will be a smaller sections of the nanostructures that will be non-height-aligned. Furthermore, by not having to height align the nanostructures using an expensive etching, grinding, or similar method step, it is possible to achieve a less expensive end product. The present invention also relates to a corresponding field-emission display.
