Marna Liddie: It is an LCD TV, but uses LEDs as a backlight.
Bob Pucella: TVs currently sold as "LED" are LCD TVs which use LEDs for the backlight, rather than CCFL.LCD panels work by applying a current through a nematic liquid, which affects its optical properties (the degree of current twists its polarity). With polaroid filters on either surface of the LCD glass, the end effect of the principle basically controls light passage through the assembly. Display class LCDs have backlights, and usually an RGB filter array, to make them color. Indicator class LCDs (as on a watch or calculator) will be monochrome so have no color filter or a single color filter to achieve the desired effect. For them, they likely use Electro-Luminescent backlight, LED, an incandescent bulb, or no backlight at all, but have a reflector, which reflects the ambient light in front of it....Show more
