Abstract
The present invention relates to display manufacturing technology, especially for a dielectric-free triode field emission display device based on double-gate/single-cathode type electron emission units and the device drive methods. This device comprises parallelly positioned anode and cathode/gate plates, during production, gate/cathode/gate electron emission units are set on the cathode/gate plate side by side. The spacing between cathode and gate electrodes is vacuum circumstance. For each cathode, an anode is positioned on the anode plate, facing the cathode. And the voltages applied on the cathode and gate electrodes are to scan and the anode voltage is to adjust the signal. When the electrodes on the cathode/gate plate take on fixed roles, fixed voltages are used to drive the device. When these electrodes on the cathode/gate plate can be used interchangeably as cathode or gate electrodes, respectively, pulse scanning method is used to drive the device.
