A method of transferring imprint carbon nano-tube (CNT) field emitting
source is disclosed. Firstly, cathode lines are screen printed on a
substrate. Then a dielectric layer formation on the cathode lines and
substrate is followed. Afterward, gate lines formed on the dielectric
layer by screen printing are performed. Next a patterning process is
carried out to form openings. Subsequently, an imprint negative mold is
dipped with CNT paste and imprinted the CNT paste on the cathode lines
through the openings. After drawing of pattern from the imprint mold, the
CNT paste is cured by annealing. Since the emitting sources are formed
through the imprint negative mold, as a result, the size and shape can be
predetermined. Moreover, the intervals between gate line and the emitting
source are readily control, which resolve the circuit short problem
between gate and cathode. Consequently, the current density, brightness,
and uniformity of the emitter sources are significantly improved.
