FLUORESCENT LIGHT EMISSION DEVICE

PURPOSE:To drive many electrodes with a small number of bits by providing a circuit which selects and drive every two adjacent linear electrodes in one group, and applying a specific potential to unselected linear electrodes and a circuit which driving the electrodes in the other group. CONSTITUTION:An anode electrode group 6 of beltlike electrodes where fluorescent bodies are adhered and a control electrode group 7 of linear electrodes which accelerate and control electrons emitted from cathode electrodes toward the fluorescent bodies are held airtightly in an enclosure 8 under a vacuum and each control electrode 7 is distributed and connected to two control electrode driving circuits 10 and 11. Then an anode electrode driving circuit 9 supplies a timing signal from a timing control circuit 12 and drives selected anode electrodes 6 and the control electrode driving circuits 10 and 11 drive two adjacent control electrodes 7 and 7 selectively while scanning them and apply the specific negative potential to control electrodes 7 which are not selected. Consequently, many electrodes can be driven by the driving circuits which handle a small number of bits.
