Why does it sound unlikely? Don't all backlit displays modify the color of the
light source when the light goes through the LCD color filters? Granted the
current multicolor arrays are well balanced to those color filters, but wouldn't it
be cheaper, in the long run, to produce a broad spectrum LED and let the
LCD filters do their own thing?
