Decreasing the Driving Voltage of Double-Gate Field Emission Display by Adding a Metallic Gate

摘要

The field emission display device working on doublegate driving principle can integrate high-temperature grown carbon nanotubes and WOX nanowires with high emission current and is easy to achieve high brightness. However the high driving voltage of this structure is a problem that limits the practical application of double-gate driving principle FED. In order to solve this problem, additional metallic gate is added to this structure. The simulation results show that adding a suitable metallic gate with proper geometric parameters can decrease the lower-gate voltage of the device.
