    • An improved FED driving method, which uses a voltage control different from the prior FED, to turn an electron beam on/off and increase the resolution. The improved FED driving method is characterized in increasing a positive voltage applied to the FED's anode, grounding the FED's emitter and applying a negative voltage to the FED's gate. When driving the FED, the anode can pull electron beam out of the cathode with high accelerate voltage and the applied negative voltage on the gate can turn the electron beam on/off. As such, this allows a higher resolution because the electron beam is not influenced by the gate's lateral attraction and high lighting efficiency with high anode accelerate voltage.
    • 使用与先前的FED不同的电压控制的改进的FED驱动方法来打开/关闭电子束并提高分辨率。 改进的FED驱动方法的特征在于增加施加到FED阳极的正电压,将FED的发射极接地并向FED的门施加负电压。 当驱动FED时,阳极可以以高加速电压将电子束拉出阴极,并且栅极上施加的负电压可以打开/关闭电子束。 因此,这允许更高的分辨率,因为电子束不受栅极的横向吸引和高阳极加速电压的高照明效率的影响。
