<p>An organic EL display luminance control method includes step 1 of calculating a luminance accumulation value for each screen according to a video input signal and step 2 of controlling the amplitude of the video input signal according to the luminance accumulation value calculated in step 1 and supplying the video signal after amplitude control to an organic EL display. According to another aspect of the invention, there is provided a cellular telephone having the organic EL display in which camera exposure control information is used to judge the brightness around and control the display luminance of the organic EL display. According to still another aspect of the invention, there is provided a cellular telephone having the organic EL display in which the direction of the display screen of the organic EL display is used to judge the brightness around and control the display luminance of the organic EL display.</p> |
