ABSTRACT:
A current controlled field emission display includes a pair of pulsed transistors that charge and discharge capacitance within the field emission display. The capacitance may be a separate circuit element or may be the parasitic capacitance of the integrated transistors and related circuitry. Various circuit configurations are employed to control charge transfer to and from the capacitance. The control circuit is driven by a series of pulse pairs where the first pulse in each pair controls charging of the capacitance and the second pulse controls discharging of the capacitance through the emitter set.
