Spacers are very important in field emission displays (FEDs), which can separate the cathode and the anode panel. We have investigated the impact of spacers on the field emission properties of a large-area FED. Simulation results showed that spacers would change the electric potential distribution inside FEDs, and would further affect the display uniformity. In FEDs with spacers of a low relative...
Field emission properties of a planar triode structure with double cathodes have been investigated. ZnO nanotetrapod emitters mixed with carbon nanotubes(CNTs) were fabricated by the screen-printing method. The potential distribution, electron trajectoryies distribution and current density distribution were simulated in detail with CST PARTICLE STUDIO code. A higher field emission density current...
