Display with non-homogenous spectral transmission curve

摘要

A display having a substrate is provided. The substrate is at least partially made of a partially transparent material having a non-homogenous spectral transmission curve. The substrate has a display face and a rear face with at least one luminous element disposed in the region of the rear face. The luminous element includes at least two base color lamps, where the base color brightness of at least one of the base color lamps is different, in order to compensate for the spectrally non-homogenous transmission curve of the substrate.

1. A display comprising:
a substrate at least partially composed of a colored partially transparent material, the substrate having a spectrally non-homogeneous transmission curve, whereby the substrate has a display face and a rear face; at least one luminous element disposed in a region of the rear face, the at least one luminous element having at least two base-color lamps; and a control unit controlling a base-color brightness of at least one of the at least two base-color lamps to correct a shift of color coordinates due to the non-homogeneous transmission curve of the substrate, wherein the substrate has a relative transmission difference dT>50% in the wavelength region between 470 nm and 630 nm and an average transmission that is greater than 0.2% for each of the spectral regions of 420-500 nm, 500-620 nm and 550-640 nm.
