In a method of driving a display apparatus, a first combination of a first
anode voltage and a first element voltage is selected to apply the first
anode voltage to the anode electrode and apply the first element voltages
to electron emitting elements selectively, during a first period. The
first combination is changed to a second combination of a second anode
voltage and a second element voltage after the first period to apply the
second anode voltage to the anode electrode and apply the second element
voltages to the electron emitting elements selectively, during a second
period. After the second period, the second combination is also change to
the first combination.
