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.
Claims15
A variably controlled display, comprising:
- an optical filter for protecting crewmember vision;
- a first light source emitting light within a first spectral power distribution and having a first radiant power output;
- a second light source emitting light within a second spectral power distribution and having a second radiant power output producing a perceived color space substantially similar to the color space perceived by a crewmember without said filter;
- a processor, for driving chromaticity and luminance values of the emitted light based on the first and second radiant power outputs;
- and
- a controller, operationally connected to the processor, that is configured to adjust one or more of the first radiant power output and the second radiant power output in response to a difference between the calculated chromaticity and luminance values and the desired chromaticity and luminance values.
