ABSTRACT:
Disclosed is an organic EL display device which includes a light emitter; a current controller controlling a current to be fed to the light emitter; a current detector detecting a value of current flowing through the light emitter as a voltage; a first switching unit switching between transmission and non-transmission of a voltage value corresponding to the detected current; a comparison amplifier comparing and amplifying the voltage value transmitted from the first switching unit to a voltage value corresponding to the image signal; a second switching unit switching between transmission and non-transmission of the voltage value being a result of the comparison and amplification; and an image signal holding capacitor charged/discharged based on the voltage value transmitted from the second switching unit, the current controller controlling the current to be fed to the light emitter based on a charging voltage of the image signal holding capacitor.
