    • 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.

    • A field-emission electron source apparatus includes a vacuum container that receives a field-emission electron source array, a target and an auxiliary electrode, and a getter pump that is disposed in the vacuum container and absorbs and removes excess gas. An electron beam emitted from the field-emission electron source array passes through a plurality of through holes formed in the auxiliary electrode and reaches the target. A space containing the field-emission electron source array and a space containing the target and the getter pump are separated substantially by the auxiliary electrode so that gas generated from the target is absorbed by the getter pump without passing through the space containing the field-emission electron source array. This makes it possible to provide a highly-reliable field-emission electron source apparatus in which the influence of gas and ions on the field-emission electron source array is eliminated or reduced.

    • The object of the present invention is to provide a driving method and a driving apparatus for a field emission device that controls emission current with stability regardless of how long the device is driven. The field emission device driving method and driving apparatus of the present invention set the actual emission current at a reference level by adjusting the amount of current which is supplied to the emitter to a reference level. The amount of current supplied to the emitter is adjusted to the reference level by increasing the driving voltage in response to driving time elapsing in a state in which the electron emission performance is sustained above the reference level. By adjusting the amount of current supplied to the emitter in a state in which the driving voltage is sustained higher than the minimum voltage, a stable amount of emission current can be sustained and electron emission without fluctuations can be realized, even when the performance of the field emission device in emitting electrons deteriorates due to driving time elapsing.
    • 本发明的目的是提供一种用于场发射装置的驱动方法和驱动装置,其无论驱动器件多长时间,都能稳定地控制发射电流。 本发明的场致发射器件驱动方法和驱动装置通过将提供给发射极的电流量调整到参考电平来将实际发射电流设定在参考电平。 通过在电子发射性能维持在基准电平以上的状态下经过的驱动时间增加驱动电压,将供给发射极的电流量调整到参考电平。 通过调节在驱动电压维持高于最小电压的状态下提供给发射极的电流量,可以维持稳定的发射电流量,并且可以实现不发生波动的电子发射。 由于驱动时间的流逝,发射电子的场致发射器件劣化。
