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.

摘要： A liquid crystal display device includes a liquid crystal display panel and a lighting device. The lighting device is supplied with alternately a first current during a period t1 and a second current during a second period t2 such that electric power E1 is lower than electric power E2. E1 is defined as (t1×ip-p(1)×Vp-p(1))/2+(t2×ip-p(2)×Vp-p(2))/2, where ip-p(1)=a peak-to-peak value of the first current, Vp-p(1)=a peak-to-peak value of a voltage across the light source during the period t1, ip-p(2)=a peak-to-peak value of the second current, and Vp-p(2)=a peak-to-peak value of a voltage across the light source during the period t2. E2 is defined as (t1+t2)×Ieff×Veff, where Ieff and Veff are effective values of the current and voltage of the light source, respectively.
