    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: The invention provides an electron beam device 1 comprising at least one field emission cathode 3 and at least one extracting electrode 5, whereby the field emission cathode 5 comprises a p-type semiconductor region 7 connected to an emitter tip 9 made of a semiconductor material, an n-type semiconductor region 11 forming a pn-diode junction 13 with the p-type semiconductor region 7 a first electric contact 15 on the p-type semiconductor region 7 and a second electric contact 17 on the n-type semiconductor region 11. The p-type semiconductor region 7 prevents the flux of free electrons to the emitter unless electrons are injected into the p-type semiconductor region 7 by the pn-diode junction 13. This way, the field emission cathode 3 can generate an electron beam where the electron beam current is controlled by the forward biasing second voltage V2 across the pn-diode junction. Such electron beam current has an improved current value stability. In addition the electron beam current does not have to be stabilized anymore by adjusting, the voltage between emitter tip 9 and extracting electrode 5 which would interfere with the electric field of electron beam optics. The present invention further provides the field emission cathode as described above and an array of field emission cathodes. The invention further provides a method to generate at least one electron beam.

    Abstract: Field emitter display (FED) assemblies and methods of forming field emitter display (FED) assemblies are described. In one embodiment, a substrate is provided having a column line formed and supported thereby. A plurality of field emitter tip regions are formed and disposed in operable proximity to the column line. At least some of the regions define different pixels of the display. A continuous resistor is interposed between the column line and at least two different pixels. In another embodiment, a column line is formed and supported by a substrate. A plurality of field emitter tip regions are formed and disposed in operable proximity to the column line. The regions define different pixels of the display. A single current-limiting resistor is operably coupled with the column line and at least two different pixels.

    Abstract: An active matrix current source controlled gray level tunable FED. The inventive FED uses active devices to convert a voltage-controlled signal into an output current and a capacitor to record and hold the voltage-controlled signal, thereby producing a low control voltage and active current source driving FED. As such, adjustment and maintenance of the gray level brightness of the FED is achieved because the brightness fixed by the active devices and the capacitor can obtain a high transient brightness when the FED operates in a lower voltage and brightness, thereby producing a high average brightness and avoiding an arc from high-voltage operation or poor vacuum.
