Organic EL display apparatus

摘要

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.
