Abstract :
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 dielectric constant, the enhanced display uniformity can be achieved.
