Abstract:
A method of conditioning a field emission display, the field emission display having an anode, a gate electrode and an emitter cathode, the method comprising the steps of:driving the anode of the field emission display to a threshold voltage;controlling an emission current of the field emission display to increase from a substantially zero level to a maximum level, wherein the step of controlling is performed after the step of driving to avoid formation of electric arcs in the field emission display when the field emission display is initially turned on;decreasing the emission current of the field emission display from the maximum level to the substantially zero level;disabling the anode of the field emission display, wherein the step of decreasing is performed prior to the step of disabling to direct the electrons towards the anode and to prevent the electrons from striking the gate electrode when the field emission display is turned off; andproviding a gas-trapping device to trap the contaminants.
