ABSTRACT:
The disclosed flat panel field emitter display (FPFED) comprises a first impedance that carries all of the current to all of the micropoint emitters of one or more (preferably one, typically fewer than about five, always fewer than all the pixels of a given row or column of the display) pixels. Provision of the first impedance can provide self-compensation to the involved pixel, making it possible to substantially reduce the required number of micropoint emitters/pixel and color. This in turn can lead to increased speed of the display, and/or to lower power consumption. The first impedance advantageously is a capacitor rather than a resistor, and embodiments that comprise a capacitive first impedance are disclosed. Other advantageous optional features are also disclosed. These include provision of gate impedances, of photoconductive elements, of an auxiliary gate electrode, or of gettering means.
