A current controlled field emission display includes a controller that provides a pair of pulsed clocking signals that allows current to flow from ground potential to an emitter in the field emission display during each clocking signal pulse. The number of electrons, and thus the intensity of the light will depend upon the number N of clocking signal pulses during an activation interval. In one embodiment, each of the pulsed signals includes a number N of pulses that corresponds to a desired intensity of pixels. The pulsed signals are formed by gating a clock signal in response to digital data applied to the display such that the transfer of electrons is controlled directly by the digital data. In another embodiment, the pulsed signals are produced by comparing a decoded image signal to counts from a high speed counter.
