About Led tv

1 A LED-backlit LCD is a liquid-crystal display that uses LEDs for backlighting instead of traditional cold cathode fluorescent backlighting. LED-backlit displays use the same TFT LCD technologies as CCFL-backlit LCDs, but offer a variety of advantages over them.

2 Features of LED backlit LCD TVs

They deliver better viewing angles than other LCD TVs; LEDs are long-lasting; LEDs are more energy efficient than their CCFL counterparts, and better than plasma Tvs and much better than CRTs; LEDs don't use mercury like some other backlighting methods.

3 How does an LED TV work? The way an LED TV works is, again, via a backlight, which is partially composed of two layers of polarizing material with a liquid crystal solution between them. When an electric current passes through the liquid solution, it causes the crystals to align so that light is transmitted.
