IPC: H01J1/30
Filed: 1999-06-12
Abstract: PURPOSE: A RF(Radio Frequency) driving FED(Field Emission Display) is provided to reduce the damage of electrodes and the pollution of an electron emission space. CONSTITUTION: A RF signal is fed between RF/cathode electrodes(42,52). A positive voltage is fed to a gate electrode(58). An electric field is hung between the gate/cathode electrodes(58,52). An electron(50) is generated from the cathode electrode(52) when the voltage difference between the gate/cathode electrodes is over a threshold voltage. The electron(50) is generated by the RF signal. The electron ionizes electrons of discharging gas and emits secondary electrons by clashing. The secondary electrons ionize electrons of other discharging gas continuously by clashing. An avalanche event to increase electrons and gas ions is generated by repeated clashes between the secondary electrons and the electrons of discharging gas. The increased electrons(50) generate a red, a green or a blue visual ray by exciting a fluorescent member(45). Thereby, the brightness is increased.
