Abstract:
1. A method of manufacturing an active-matrix display comprising first to third pixels each including an emitting element and different in emitting color from one another, and first to third signal output circuits outputting video signals to the first to third pixels, respectively, comprising: a first step including writing a first adjustment video signal on the first pixel to allow the first pixel emit light and, in this state, measuring luminance and chromaticity as first monochromatic color data; a second step including writing a second adjustment video signal on the second pixel to allow the second pixel emit light and, in this state, measuring luminance and chromaticity as second monochromatic color data; a third step including writing a third adjustment video signal on the third pixel to allow the third pixel emit light and, in this state, measuring luminance and chromaticity as third monochromatic color data; a fourth step including updating the first to third adjustment video signals based on the first to third monochromatic color data such that luminance and chromaticity, of a combination of the first to third pixels when the first to third pixels emit light simultaneously, are predetermined target values when the updated first to third adjustment video signals are written on the first to third pixels, respectively to allow the first to third pixels to emit light simultaneously; a fifth step including writing the updated first to third adjustment video signal on the first to third pixels, respectively to allow the first to third pixels to emit light simultaneously, and in this state, measuring luminance and chromaticity, of a combination of the first to third pixels when the first to third pixels emit light simultaneously, as mixed color data; and a sixth step including, in a case where the mixed color data is within a predetermined range and power consumption of the display or the first to third pixels at the measurement of the mixed color data exceeds a predetermined upper limit, updating the first to third adjustment video signals such that the power consumption is equal to or lower than the upper limit, and the method including setting the first to third adjustment video signals updated finally as maximum values of the video signals to be written on the first to third pixels, respectively.
