摘要： The present invention relates to a display system comprising an illumination unit, wherein a predetermined light spectrum can be generated with the illumination unit. The mean luminous intensity can thus be decreased or increased over the wave length range of 420 nm to 500 nm relative to the mean luminous intensity above and below said wave length range such that the predetermined light spectrum is more than a light spectrum generated without said decrease or increase.
