  • Publication number: 20080158115
    Abstract: A method of displaying an input signal (IV) on a full color LED display is discussed wherein the display has pixels (11) comprising at least four LED's (PLi) which respectively emit light with four primary colors. The method comprises converting (SC) the input signal (IV) into drive signals for the at least four LED's (PLi). The converting (SC) comprises: (i) determining (RD) valid ranges (VRi) of at least two of the drive signals (DSi) to obtain a color of the combined light emitted which fits the input signal (IV), (ii) determining (LD) a gradation or lifetime indication (LTi) of the at least two LED's (PLi) for associated ones of the drive signals (DSi) within the valid ranges (VRi), and (iii) determining (CD) a combination (DCi) of values of drive signals (DSi) providing substantially the minimum degradation, or the maximum lifetime, of a combination of the at least two LED's (PLi) based on the degradation or lifetime indications (LTi).
