Patent ID: 8535109

Claim:
A method for making an incandescent light source display comprising steps: providing a substrate and a drawn carbon nanotube film comprising a plurality of carbon nanotubes substantially aligned along a same direction; forming a plurality of electrode pairs on a surface of the substrate, the surface of the substrate defining a plurality of pixel locations, the plurality of electrode pairs being spaced from each other and located on the plurality of pixel locations in one to one manner, each of the plurality of electrode pairs comprising a first electrode and a second electrode spaced from the first electrode; covering the plurality of electrode pairs with the drawn carbon nanotube film, the drawn carbon nanotube film suspending between the first electrode and the second electrode and having the plurality of carbon nanotubes substantially aligned an X direction from the first electrode to the second electrode in each of the plurality of electrode pairs; cutting the drawn carbon nanotube film between the first electrode and the second electrode along the X direction to form at least one carbon nanotube strip in each of the plurality of pixel locations; removing the drawn carbon nanotube film between any adjacent two of the plurality of pixel locations; and shrinking the at least one carbon nanotube strip into at least one carbon nanotube wire by using an organic solvent.
