Abstract
An organic electroluminescence display device includes a display panel including pixels. The pixels each include a light-emitter, driver and capacitor. A storage is configured to store a correction parameter for each of the pixels for correcting, in accordance with characteristics of each of the pixels, an image signal input from an external source. A controller is configured to, for each pixel of the pixels, obtain a corrected signal voltage by reading the correction parameter corresponding to the pixel from the storage and multiplying the image signal corresponding to the pixel by the correction parameter corresponding to the pixel. The storage is configured to store a gain and not an offset as the correction parameter.
