ABSTRACT:
A display including plural field emission devices arranged in a pixel matrix. Each of these field emission devices includes an opening in an insulating layer of a supporting substrate, an upwardly extending cathode having a tip disposed centrally within the opening, and a gate electrode disposed circumferentially about the rim of the opening aligned substantially concentric to the cathode tip. Also, thin film transistor transmission gates are disposed proximate to each of the field emission devices and are selectively operable to control transmission of data signals to the gate electrode of the field emission devices to which they are adjacent.
