LED TV vs. LCD TV

Traditional LCDs have used some form of flourescent lighting from tubes to much more advanced flat arrays of lights. LED TVs use Light Emitting Diodes to light the LCD panel. Just as there are different styles of flourescent lights in traditional LCDs there are also different styles of LED backlighting. There are LED TVs like the Sony Bravia KDL-55XBR8 that have a panel of LED lights behind the LCD panel. In the Sony the LEDs are tri-colored and can be controlled in banks for an effect called "local dimming". This allows darker areas of the picture to have the backlighting dimmed behind them resulting in better contrast and black levels. In the Luxia line of Samsung LED TVs, the LED lights are surrounding the edge of the panel.

LED TV vs. Plasma

New LED TV are changing the nature of how we view LCD TV in such a way that we must re-assess the advantages of LCD and Plasma over one another. All LED TVs contain an LCD display element (front panel). The difference of LED TVs lies in the backlight. Rather than the standard florescent backlighting systems (CCFL) of the past, LED TVs have LED bulbs (light emitting diode) as the backlight for the LCD panel.

Advantages of LED TV Technology

The viewing angle on LCD Televisions with LED back lighting has improved dramatically to plasma-like levels of 75 degrees with no contrast level degradation on some of the best ones.
The black levels on the new LED TVs has improved to plasma like black levels while contrast levels still lag the best plasmas buy hundreds of post calibration points
Brightness on LED based LCDs is better than the traditional flourescent bulbs
LED TVs will have better consistency of color information over time than traditional LCDs
LED backlit Televisions should in theory have a better lifespan than traditional LCD TVs or plasmas
