摘要: In a method of driving an organic-electroluminescence display device, when a small white pattern is displayed at the same position of the black background for a long time, burn-in of the white-pattern displayed portion is prevented without a feeling of a sense of the contrast lack. The organic-electroluminescence display device includes an organic-electroluminescence element panel, and an input-signal processing circuit into which an image signal is to be input. The input-signal processing circuit includes a luminance detection circuit for detecting average luminance of the input image signal, and a luminance control circuit. The luminance control circuit, when, as an image on the organic-electroluminescence element panel, a high-luminance pattern continues to be displayed longer than a time-interval T1 on a low average-luminance screen, lowers the luminance of the pattern down to a predetermined value with a time-interval T2 after T1.
