摘要:
A display panel driving device and driving method for providing high quality images without irregular luminance even after long-time use. The value of the light-emission drive current flowing when causing each light-emission elements bearing each pixel to independently emit light in succession is measured, then the luminance is corrected for each input pixel data based on the above light-emission drive current values, associated with the pixels corresponding to the input pixel data. According to another aspect, the voltage value of the drive voltage is adjusted in such a manner that one value among each measured light-emission drive current value becomes equal to a predetermined reference current value. According to a further aspect, the current value is measured while an off-set current component corresponding to a leak current of the display panel is added to the current outputted from the drive voltage generator circuit and the resultant current is supplied to each of the pixel portions.
