Abstract:
A display device comprising:a screen defined by a matrix of pixels on which an image represented by an image input signal is to be displayed; first light-emitting elements, one for each of the pixels, each of said first light-emitting elements being actuated to produce light of a first color in a corresponding one of the pixels; second light-emitting elements, one for each of the pixels, each of said second light-emitting elements being actuated to produce light of a second color different from the first color in a corresponding one of the pixels; and a light-emitting element controlling circuit responsive to the image input signal to control actuation of each of said first and second light-emitting elements to form the image on said screen, said light-emitting element controlling circuit actuating said second light-emitting element in each of the pixels to visually mix the light of the second color with the light of the first color produced by a corresponding one of said first light-emitting elements in a given proportion to minimize a difference in chromaticity of the lights of the first color between the pixels.
