Abstract: The invention provides an electrophoretic deposition method of CNTs for a field emission device. It uses a triode structure having gates and a proper arrangement of applied voltages to improve the selectivity of the conventional EPD method. The electric field around the gates repels the charged or polarized nanostructure suspension in the electrophoresis bath and prevents the charged or polarized nanostructure materials from depositing in the neighborhood of the gates. Therefore, the nanostructure materials are selectively deposited on the cathode. An electrical short circuit between the gates and the cathodes can be avoided. It does not require a masked sacrificial layer, and therefore keeps the manufacturing process simple and the cost down.

It also reduces the driving voltage substantially. Therefore, the display in the dark is achieved by adjusting the voltage without changing the structure.

Abstract: 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.
