ABSTRACT:
A field emission print head capable of converging electrons and having a structure such that odd order gate lines are connected to a first gate lead electrode, even order gate lines are connected to a second gate lead electrode. When the first gate lead electrode is selected and operated, the potential of the second gate lead electrode is made to be a low level. Since the odd order gate line is disposed between the low level even order gate lines, emitted electrons can be converged. When the second gate lead electrode is selected and operated, also emitted electrons can be converged. Each gate line has field emission cathodes disposed in a zigzag configuration. Since the first gate lead electrode is made to always be a low level as a converting electrode, the field emission print head can easily be manufactured.
