Patent ID: 7403196

Claim:
An organic EL display apparatus which has plural pixels arranged in a matrix form, selects a pixel from the plural pixels according to a pixel selection signal and causes the selected pixel to emit light according to an image signal, 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 according to the pixel selection signal; an amplifying section which performs current-voltage conversion of the current transmitted by the first switching section and amplifies the current transmitted; 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 according to the pixel selection signal; and an image signal holding capacitor which is charged or discharged according to the voltage value transmitted by the second switching section, wherein the current control section controls the current to be flown to the light emitting section according to the charging voltage of the image signal holding capacitor.
