Sorry everybody. The point I was trying to make that LCD/LED monitors
have "individual LED backlights for each pixel". Because the LED is
already a coloured primary light source of greater purity than a fluoro
backlight + colour filter can produce, you get a greater gamut. And,
because the LED can be turned off altogether, you can get better blacks.
