CIRCUIT DE CONTROLE D'UN PIXEL A COORDONNEES CHROMATIQUES VARIABLES |
摘要 |
<p>A pixel with variable chromatic coordinates comprises a plurality of color sub-pixels consisting of a light emitter and a color filter. The light emitters are identical and have an emission spectrum that is able to be modulated according to their supply voltage and/or current. The pixel control circuit supplies each color sub-pixel with a supply voltage and/or current dependent on the color of the sub-pixel for its emission spectrum to approximate the transmission spectrum of the associated color filter. Control means enable the application time of the supply voltage and/or current to be modified according to the color of the sub-pixel to obtain a predetermined mean luminance during a predetermined period.</p> |
