Patent ID: 8646939

Claim:
A display system for optical display of analog or digital information, comprising: a display unit and an illumination unit that illuminates the display unit on the basis of an additive or subtractive color synthesis with a predetermined light spectrum; or an illumination unit that is configured as a self-illuminating display unit which produces the display of the information on the basis of an additive or subtractive color synthesis with a predetermined light spectrum; wherein a predetermined light spectrum can be produced with the illumination unit, the light intensity of which light spectrum is reduced or increased over the wavelength range of 420 nm to 500 nm relative to the light intensity/intensities above and/or below this wavelength range and/or the light intensity/intensities of which is/are increased above and/or below this wavelength range relative to the light intensity in this wavelength range such that the predetermined light spectrum is metameric to a light spectrum produced without this reduction and/or increase.
