Method for sequentially electrophoresis depositing carbon nanotube of field emission display

摘要

A method sequentially performs electrophoresis depositing carbon nanotube of field emission display. Only one cathode strip is subjected to electrical field at one time during electrophoresis deposition. Therefore, the electrophoresis deposition is confined to local area. A cathode plate includes a plurality of cathode strips and the cathode strips sequentially have potential difference with respect to the anode strips, whereby only one electrical field is present for one pixel at one time and carbon nanotube is formed at that pixel. The cathode strips are sequentially applied with voltage for global electrophoresis deposition.
