Abstract
A display having a variably controlled backlight and/or driver is disclosed. The backlight includes a first light source that emits light within a first spectral power distribution and has a first radiant power output. A second light source emits light within a second spectral power distribution matched to an optical filter for producing a perceived chromaticity and luminosity matching the perceived display appearance without the optical filter.
