    Abstract: Provided is a field emission display (FED) in which field emission devices are applied to a flat panel display. The FED includes: a cathode plate including a substrate, first and second thin film transistors (TFTs) that are serially connected on the substrate, a field emitter disposed on a drain electrode of the second TFT, a gate insulating layer having a gate hole surrounding the field emitter, and field emission gate electrodes disposed on the gate insulating layer; and an anode plate including a substrate, and red, green, and blue phosphors disposed on the substrate, wherein the cathode plate and the anode plate are vacuum-packaged parallel and opposite to each other. According to the present invention, uniformity of the FED panel can be significantly improved, and an inherent source-drain leakage current of the TFT can be significantly reduced, so that a contrast ratio of the FED can be significantly enhanced.

    Abstract: The invention includes field emitters, field emission displays (FEDs), monitors, computer systems and methods employing the same for providing uniform electron beams from cathodes of FED devices. The apparatuses each include electron beam uniformity circuitry. The electron beam uniformity circuit provides a grid voltage, VGrid, with a DC offset voltage sufficient to induce field emission from a cathode and a periodic signal superimposed on the DC offset voltage for varying the grid voltage at a frequency fast enough to be undetectable by the human eye. The cathodes may be of the micro-tipped or flat variety. The periodic signal may be sinusoidal with peak-to-peak voltage of between about 5 volts and about 50 volts.

    Abstract: A field emission display device (1) includes a cathode plate (20), a resistive buffer (30) in contact with the cathode plate, a plurality of electron emitters (40) formed on the buffer, and an anode plate (50) spaced from the electron emitters. Each electron emitter includes a rod-shaped first part (401) and a conical second part (402). The buffer and first parts are made from silicon nitride. The combined buffer and first parts has a gradient distribution of electrical resistivity such that highest electrical resistivity is nearest the cathode plate and lowest electrical resistivity is nearest the anode plate. The second parts are made from niobium. When emitting voltage is applied between the cathode and anode plates, electrons emitted from the electron emitters traverse an interspace region and are received by the anode plate. Because of the gradient distribution of electrical resistivity, only a very low emitting voltage is needed.
