Disclosed is an organic EL display apparatus comprising: a light emitting
section; a current control section which controls a current to be flown
to the light emitting section; a photoelectric converting section which
generates a current upon detecting light emitted from the light emitting
section; a first switching section which switches between transmission
and non-transmission of the current generated; an amplifying section
which performs current-voltage conversion of the current transmitted by
the first switching section and amplifies it; a comparison amplifying
section which performs comparison and amplification of a voltage value
obtained by the amplification and a voltage value corresponding to the
image signal; a second switching section which switches between
transmission and non-transmission of the voltage value resulting from the
comparison and amplification; and an image signal holding capacitor which
is charged or discharged according to the voltage value transmitted by
the second switching section.
