    摘要: There are provided a liquid crystal drive method, a liquid crystal display system and a liquid crystal drive control device, which can realize low power consumption at an alternating current drive of a liquid crystal panel. A common voltage given to a common electrode of a liquid crystal is switched between a positive phase and a negative phase. Display data is converted in such a manner that first display data and second display data selecting two of a plurality of gradation voltages in which magnitudes of potential differences in the pixel electrodes in the positive phase and the negative phase with reference to the common voltage corresponding to display data in a display memory are the same are in the same bit pattern except for one specified bit. For example, bit allocation of positive and negative gradation display data is made in such a manner that low-order bits other than the highest order bit are symmetric up and down in binary with respect to the middle.

    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.
