ABSTRACT:
The field emission device includes, in addition to the main, conventional array of field emission devices and its associated driving circuits, an additional, separate, pixel-sized group of field emission devices close to, but separated from, said main array. Electrons emitted by the additional pixel are collected on a separate, non-fluorescent, anode, and additional circuitry is provided, including a feedback loop from a detector of the additional pixel's cathode current to the gate voltage supply of the main array. Consequently, the voltage of the gate lines varies in inverse proportion to the cathode current of the additional pixel. This results in a display whose brightness is constant even when turned on for the first time or after a period of idleness. A method for manufacturing the device is also available.
