Abstract:
1. A method for driving a flat-type display device which includes: (A) a cathode panel having M strip-form first electrodes extending in a first direction and N strip-form second electrodes extending in a second direction different from the first direction, and having N×M electron emitter areas composed of overlap regions between the first electrodes and the second electrodes; and (B) an anode panel having a fluorescent region and an anode electrode, the cathode panel and the anode panel being joined together at their edges through a joint member, the cathode panel and the anode panel having therebetween spacers extending in the first direction arranged in P rows, the method comprising the steps of: in the non-display operation period of the flat-type display device, determining a normalized second current I in the actual display operation period of the flat-type display device, setting the driving conditions for the electron emitter areas on the basis of the normalized first current I
