DISPLAY SYSTEM HAVING CIRCADIAN EFFECT ON HUMANS

摘要

A display system includes an illumination unit in which a predetermined light spectrum can be produced with the illumination unit, the average light intensity of which light spectrum can be reduced or increased over the wavelength range of 420 nm to 500 nm relative to the average light intensity above and below this wavelength range such that the predetermined light spectrum is greater relative to a light spectrum produced without this reduction or increase.
