Abstract
An integrally formed field emission device and electron emission control circuit wherein electron emission is controlled by a current source semiconductor circuit and a semiconductor switch coupled such that upon application of switching information to the switch the field emission device is enabled to an ON mode for the time duration of the information and during which time the current source provides a determined electron current to be subsequently emitted by the emitter of the field emission device. A field emission device array and electron emission control circuits is provided to effectively control electron emission for each field emission device in the array.
