Samsung believes that by 2010, 30% of all LCD televisions will include LED backlights
instead of the conventional flourescent used in most sets now. What's different from the LED units we've seen before is that Samsung wants to use white LEDs, with single diodes custom-coated to produce the same backlight previously requiring combinations of red, green, and blue bulbs. Samsung recently invested
in Intematix, which produces custom phosphor coatings for LED bulbs to create uniform color -- required in a television to faithfully reproduce colors. Until recently costs have been higher for LED backlight units, keeping them relegated to higher-end models. Samsung claims the single bulb process reduces costs by 40%, but time will tell whether white-only LEDs are truly better or cheaper than tri-color LEDs, or if they are just the next "Reveal lightbulb" marketing gimmick.
