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.
