Abstract
The present invention provides an organic light emitting display device in which light emitted by an OLED whose luminance is adjusted for detection of deterioration does not stand out as compared to light emitted by other OLEDs, thereby not producing an unpleasant sensation for users. A calculation unit in a display control unitsets, for a target pixel, a driving signal Out(C)=V. For a peripheral pixelhorizontally located immediately before the target pixel, the calculation unit calculates a driving signal Out(C−1)=In(C−1)−V(In(C))/2. For a peripheral pixelhorizontally located immediately after the target pixel, the calculation unit calculates a driving signal Out(C+1)=In(C+1)−V(In(C))/2.
