Design of nMOS driving circuits integrated with field emitter arrays

Describes the active device controlled FEA, like MCFEA (MOSFET controlled FEA). When integrating the driving circuit with FEA, the processing sequence is compatible with MOSFET and the active device in the pixel for driving FEA can be attained simply. Ideally, it requires only as high as the threshold voltage to drive an MCFEA, which gives extra benefits including stable and uniform emission current. It also reduces driving load from the capacitance of FEA gate to that of MOSFET gate. The one-transistor and one-FEA configuration is the simplest and most suitable for one-chip FED. The MOSFET acts as a line selection switch by driving the gates of MOSFET and the common sources are controlled in current or voltage driving mode.
