    • A field emission device having cold cathode devices including an emitter and a lead electrode, and the field emission device is provided with the plural kinds of cold cathode device groups classified based on the emission property of the cold cathode device. This field emission device has a member for allowing the cold cathode device group to perform emission by successively changing the cold cathode device group that mainly performs emission based on the difference in the emission property. Thus, it is possible to maintain the emission current at a predetermined necessary value or more and to realize the long lifetime of the field emission device.

    • An electron emitting apparatus includes a lower electrode, an emitter section made of a dielectric material, a plurality of upper electrodes having micro through holes, and a collector electrode opposing the upper electrodes. In this electron-emitting apparatus, electrons are accumulated in the emitter section by controlling the potential difference (drive voltage) between the lower and upper electrodes with respect to the potential of the lower electrode to a negative predetermined voltage. At this time, the collector electrode of the electron-emitting apparatus is grounded. Thus, unnecessary electron-emitting is suppressed. Subsequently, the drive voltage is changed to a positive predetermined voltage. As a result, polarization reversal occurs in the emitter section, and accumulated electros are emitted through the micro through holes in the upper electrodes by Coulomb repulsion. At this time, a positive voltage Vc is applied to the collector electrode to give large energy to accelerate the electrons.
    • 电子发射装置包括下电极,由介电材料制成的发射极部分,具有微通孔的多个上电极和与上电极相对的集电极。 在该电子发射装置中,通过将下电极和上电极之间的电位差(驱动电压)相对于下电极的电位控制为负的预定电压,将电子累积在发射极部分。 此时,电子发射设备的集电极接地。 因此,抑制不必要的电子发射。 随后,驱动电压变为正的预定电压。 结果,在发射极部分发生极化反转,并且通过库仑斥力通过上电极中的微通孔发射积聚的电子。 此时,向集电极施加正电压Vc以产生大的能量来加速电子。
