Abstract
On the basis of new triode-type field emission arrays (FEAs) and the so-called swap-gate driving method for a 3-in.-diagonal flat lamp using carbon nanofiber (CNF) emitters in our previous research, the characteristics of our flat lamp were investigated according to the swap-gate driving conditions. It was found that the longer the gate-pulse width (duration time), the higher the anode current. Additionally, in the case of a fixed gate-pulse width, the anode current increased as the gate frequency increased. One particularly interesting experimental result was that the emission current (Ia) increased with the shortening of the pulse width of the gate when the sum of the gate-pulse widths per second was equal.
