A method for driving a flat-type display device which includes a cathode
panel having first electrodes and second electrodes and an anode panel,
the cathode panel and the anode panel having spacers is provided. The
method includes the steps of: in the non-display operation period of the
flat-type display device, determining a normalized first current from a
first current by non-display-driving the electron emitter areas near the
spacers, and determining a normalized second current from a second
current by non-display-driving the electron emitter areas which are not
near the spacers; and 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 and normalized
second current so that the electron emission conditions in the electron
emitter areas near the spacers and not near the spacers are substantially
the same.
