What are Back-lit LED TVs?
LED TVs described as backlit, or full array, are illuminated by rows of LED’s arranged
directly behind the screen, rather than just around the edges. Back-lit LED TVs
include an array of LED’s arranged directly behind the LCD screen. The LED’s can
be dimmed but not independently. Brighter pictures and more energy efficient than
CCFL but not as thin as Edge-lit. (Sharp LE700 series are Back-lit LED’s.) An important
thing to note is that just because an LED is backlit does not mean there is an LED
for each pixel. Actually, no such TV exists. In the case of the Sharp LE700, there
are only a couple dozen LED’s behind the whole LCD screen. Usually, one LED is responsibly
for lighting several thousands of pixels. This means there is still room for improvement
as LEDs get smaller and less expensive. The biggest thing to remember about LED
TVs is that they offer a better picture than CCFL, they are more energy efficient
(by up to 40%) and are usually thinner. LED backlit televisions are the latest generation
in LCD TV technology. Overall, LED backlit televisions offer great improvements
over standard CCFL backlit LCD’s. The standard backlit LED television places white
LED’s directly behind the LCD panel. With televisions, differences come down to
the size, the length, width, height and picture
