Abstract:
1. A display method including: supplying a selection signal for selecting pixels to be luminous in a predetermined scanning cycle, each of the pixels including a luminescence element that individually becomes luminous depending on a current amount and a pixel circuit for controlling a current applied to the luminescence element according to a voltage signal; supplying to the pixels the voltage signal according to an input picture signal, the pixels, the scan lines, and the data lines arranged in a matrix pattern; multiplying primary colour signals of the picture signal respectively by adjustment values for the respective primary colour signals based on a voltage-current characteristic; calculating average luminance for a first area, based on the picture signal multiplied by the adjustment values; calculating average luminance for a second area, based on the picture signal multiplied by the adjustment values, the second area being smaller than the first area; selecting, as an average luminance, a larger value out of an average luminance calculated for the first area and an average luminance calculated for the second area; and setting an effective duty according to the average luminance.
