Abstract:
A method of conditioning a field emission display, the method comprising he steps of:a) providing the field emission display with electron-emissive elements for emitting electrons, a gate electrode for controlling electron emission from the electron-emissive elements, and a display screen for collecting the electrons;b) enabling the display screen to establish a voltage differential between the display screen and the electron-emissive elements;c) following enabling of the display screen, enabling the gate electrode by delaying substantial electron emission from the electron-emissive elements until the voltage differential has been established to direct the electrons towards the display screen and to substantially prevent the electrons from striking the gate electrode; andd) following enabling the gate electrode, lowering a voltage of the display screen to a predetermined level;e) following lowering the voltage of the display screen, increasing a voltage of the gate electrode to increase an emission current; andf) repeating the steps (d) and (e) until a threshold voltage at the display screen is reached.
