52.2: Display with Arbitrary Primary Spectra

Abstract

Individual differences in colour sensation of a single display (observer metamerism) can be reduced by synthesizing and adapting the primary spectra to the physiological spectral response of the observer. The technique can also be used to synthesize the eigenspectra in multispectral imaging, and thereby provide an alternative to multi‐primary displays.

Measuring Subjective Differences Objectively

“…In both cases, however, light emission spectra are unchanged and prone to OM. Using the CIE 2006 model, it was quantitatively shown 8 that creating sRGB chromaticities by broadening the emission peaks rather than superpositioning them resulted in a smaller OM.…”

Alternative Technologies for Mobile and Wearable Displays

“…The fact that the primary colors are only determined by the backlight makes it possible to tune the primary and white point chromaticities without losing any gray shades (clipping). Using an array of LEDs with different emission spectra also enables a display with arbitrary primary spectra (Bergquist 2008) which can be used for reproducing images captured with multispectral imaging.…”
